Detailed Description

With the continuous development of information technology, the degree of intelligence of automobiles is higher and higher, and more automobile factories use the vehicle-mounted T-BOX as the standard configuration of the automobiles. The vehicle-mounted T-BOX can be used for realizing the functions of remotely starting a vehicle, opening an air conditioner in the vehicle, adjusting a seat in the vehicle to a proper position, communicating with other communication equipment and the like.

The vehicle-mounted T-BOX can realize various functions without switching on power supply to supply power for the vehicle-mounted T-BOX. FIG. 1 is a schematic diagram of a vehicle-mounted T-BOX and a vehicle provided by the embodiment of the application. As shown in fig. 1, in a normal case, a vehicle-mounted T-BOX is powered by an in-vehicle power supply system 101 of a vehicle, and power is supplied to a power management unit 104 of the vehicle-mounted T-BOX through a T-BOX and an in-vehicle connector 103 of the vehicle-mounted T-BOX, so that the power management unit 104 supplies power to a wireless communication and processing unit 105 of the vehicle-mounted T-BOX and a T-BOX power utilization unit 106 of the vehicle-mounted T-BOX, thereby enabling the vehicle-mounted T-BOX to realize its function. For example, the onboard T-BOX communicates with other communication devices through the wireless communication and processing unit 105.

When the power supply system 101 in the vehicle is abnormal and cannot supply power, the vehicle-mounted T-BOX can operate independently using its built-in battery 107. Specifically, when the power supply system 101 is abnormal and cannot supply power to the vehicle-mounted T-BOX, the built-in battery 107 of the vehicle-mounted T-BOX replaces the vehicle-mounted power supply system 101 and supplies power to the power management unit 104 of the vehicle-mounted T-BOX, so that the vehicle-mounted T-BOX can realize the function thereof. In addition, the partial type of built-in battery 107 also supports charging, and when the power of the built-in battery 107 is used up, it can also be charged by the in-vehicle power supply system 101 of the vehicle.

However, in the case of a vehicle, the in-vehicle power unit 102 is mainly supplied with power from the in-vehicle power supply system 101. When the power supply system 101 is abnormal and cannot supply power to the in-vehicle electric unit 102, there is no technology that can supply power to the in-vehicle electric unit 102.

The embodiment of the application provides a power supply method, when a power supply system in a vehicle is abnormal and cannot supply power, a built-in battery of a vehicle-mounted T-BOX is used for supplying power to a power utilization unit in the vehicle so as to meet the emergency demand of a user.

Fig. 2 is a schematic flow chart of a power supply method according to an embodiment of the present application. The power supply method is applied to the vehicle-mounted T-BOX, and the vehicle-mounted T-BOX comprises a power supply unit which is used for providing power supply. As shown in fig. 2, the power supply method may include:

s201, the vehicle-mounted T-BOX receives a first indication signal, and the first indication signal is used for indicating a power supply unit to supply power for an in-vehicle power utilization unit of a vehicle.

Wherein the vehicle-mounted T-BOX is configured in the vehicle. The power supply unit may be a battery. In general, an in-vehicle power unit of a vehicle is supplied with power from an in-vehicle power system, but when an abnormality occurs in the in-vehicle power supply system of the vehicle, the in-vehicle power supply system cannot supply power to the in-vehicle power unit. In the embodiment of the application, in order to supply power to the in-vehicle power utilization unit when the in-vehicle power supply system of the vehicle is abnormal and the power cannot be supplied to the in-vehicle power utilization unit, the in-vehicle T-BOX can supply power to the in-vehicle power utilization unit.

In this embodiment of the application, the occurrence of the abnormality of the in-vehicle power supply system of the vehicle may be that the self-checking system of the vehicle detects that the in-vehicle power supply system has a fault, for example, the self-checking system of the vehicle detects that the electric quantity of the storage battery of the vehicle is lower than a certain threshold, or the electric quantity of the storage battery is higher than a certain threshold, and the like. The specific implementation of the fault of the in-vehicle power supply system may be determined according to an actual application scenario, and the embodiment of the present application is not specifically limited herein.

In some embodiments, when the power supply system in the vehicle is abnormal and cannot provide power supply, the vehicle can send a first indication signal to the vehicle-mounted T-BOX to indicate the power supply unit of the vehicle-mounted T-BOX to provide power supply for the power utilization unit in the vehicle. Illustratively, the vehicle may send the first indication signal to the vehicle-mounted T-BOX by using a wireless communication technology, and may also send the first indication signal to the vehicle-mounted T-BOX through a physical path.

In still other embodiments, in the case that the power supply system in the vehicle cannot provide power supply due to an abnormality, a first indication signal for indicating the power supply unit of the vehicle-mounted T-BOX to provide power supply for the power utilization unit in the vehicle may be sent to the vehicle-mounted T-BOX by the auxiliary device. The auxiliary device may be any device capable of communicating with the vehicle-mounted T-BOX except a vehicle, for example, a mobile terminal such as a mobile phone and a tablet computer. Illustratively, the auxiliary device may send the first indication signal to the vehicle-mounted T-BOX by using a wireless communication technology, and may also send the first indication signal to the vehicle-mounted T-BOX by using a physical path.

The Wireless communication technology may be Bluetooth (BT) technology, Wireless Fidelity (WiFi) technology, 2 nd Generation mobile communication technology (2G), 3 rd Generation mobile communication technology (3G), 4 th Generation mobile communication technology (4G), 5 th Generation mobile communication technology (5G), or next Generation communication technology. Of course, other wireless communication technologies are also possible, and are not specifically limited herein.

In addition, because the power supply unit of the vehicle-mounted T-BOX can provide limited power, when the power supply system in the vehicle is abnormal and cannot provide power supply, when a user has an emergency demand, the vehicle or auxiliary equipment can send a first indicating signal to the vehicle-mounted T-BOX so as to indicate the power supply unit of the vehicle-mounted T-BOX to provide power supply for the power utilization unit in the vehicle, so that the emergency demand of the user is met.

For example, in the case that the power supply system in the vehicle is abnormal, when a user needs to ignite a power supply for the engine of the vehicle, the user can trigger a corresponding button in the vehicle to enable the vehicle to send a first indication signal to the vehicle-mounted T-BOX so as to instruct the power supply unit of the vehicle-mounted T-BOX to provide power supply for the ignition system of the engine of the vehicle.

For another example, in the case that the power supply system in the vehicle is abnormal, when the user needs to open the door, the user may trigger the auxiliary device to send the first indication signal to the vehicle-mounted T-BOX by triggering the corresponding button in the auxiliary device, so as to instruct the power supply unit of the vehicle-mounted T-BOX to provide power to the electronic door opening system of the vehicle.

S202, the vehicle-mounted T-BOX controls the power supply unit to supply power to the vehicle-mounted electric unit through the external power supply circuit according to the first indication signal.

After the vehicle-mounted T-BOX receives the first indication signal, the vehicle-mounted T-BOX can control the power supply unit thereof to supply power to the vehicle interior power utilization unit of the vehicle through the external power supply circuit. In the embodiment of the present application, the external power supply circuit is a power supply path between the power supply unit and the in-vehicle power consumption unit. Which is different from a power supply path between an in-vehicle power supply system and an in-vehicle electric unit of an in-vehicle T-BOX.

For example, it is assumed that the vehicle and the vehicle-mounted T-BOX communicate with each other by using a wireless communication technology, and the wireless communication technology used is a bluetooth technology. As shown in fig. 3 and 4, in the case that the power supply system 301 in the vehicle is abnormal and cannot supply power to the power consuming unit in the vehicle, the bluetooth module 308 of the vehicle may send a first indication signal to the bluetooth module 305 of the vehicle-mounted T-BOX by using the bluetooth protocol through the trigger of the user, so as to instruct the power supply unit 307 of the vehicle-mounted T-BOX to supply power to the power consuming unit 302 in the vehicle. After the bluetooth module 305 of the vehicle-mounted T-BOX receives the first indication signal, the bluetooth module 305 of the vehicle-mounted T-BOX may transmit the first indication signal to the power management unit 304 of the vehicle-mounted T-BOX through a signal line. The power management unit 304 may control the power supply unit 307 to supply power to the in-vehicle electric usage unit 302 through an external power supply circuit. For example, the power management unit 304 supplies the power of the power supply unit 307 to the in-vehicle electric unit 302 through an external power supply circuit via the T-BOX and the in-vehicle connector 303 and the in-vehicle power supply system 301 as shown in fig. 3. Alternatively, the power management unit 304 supplies the power of the power supply unit 307 to the in-vehicle electric unit 302 through an external power supply circuit via the T-BOX and the in-vehicle connector 303 as shown in fig. 4.

For example, it is assumed that a wireless communication technology is adopted for communication between the vehicle and the vehicle-mounted T-BOX, and the adopted wireless communication technology is a 5G technology. As shown in fig. 5, when the power supply system 501 in the vehicle is abnormal and cannot supply power to the electric unit in the vehicle, the wireless communication unit 508 of the vehicle can adopt 5G technology through the trigger of the user, and the wireless communication and processing unit 505 of the vehicle-mounted T-BOX sends a first indication signal to instruct the power supply unit 507 of the vehicle-mounted T-BOX to supply power to the electric unit 502 in the vehicle through the base station and the T-BOX antenna of the vehicle-mounted T-BOX. After the wireless communication and processing unit 505 of the vehicle-mounted T-BOX receives the first indication signal, the wireless communication and processing unit 505 of the vehicle-mounted T-BOX can send the first indication signal to the power management unit 504 of the vehicle-mounted T-BOX through a signal line. The power management unit 504 may control the power supply unit 507 to supply power to the in-vehicle electric usage unit 502 through an external power supply circuit. For example, the power management unit 504 supplies the power of the power supply unit 507 to the in-vehicle electric unit 502 through an external power supply circuit via the T-BOX and the in-vehicle connector 503 and the in-vehicle power supply system 501 as shown in fig. 5. Alternatively, the power management unit 504 may directly supply the power of the power supply unit 507 to the in-vehicle power unit 502 through an external power supply circuit via the T-BOX and the in-vehicle connector 503.

For example, it is assumed that the vehicle and the vehicle-mounted T-BOX communicate with each other through a physical path, and a button is provided in the vehicle for triggering the vehicle to send a first indication signal to the vehicle-mounted T-BOX. As shown in fig. 6, when the power supply system 601 of the vehicle is abnormal and cannot supply power to the in-vehicle power consumption unit, the user may trigger the corresponding button, and at this time, the vehicle may send a first indication signal (the first indication signal is a hardware communication signal) to the in-vehicle T-BOX through a physical path between the T-BOX of the in-vehicle T-BOX and the in-vehicle connector 603, so as to instruct the power supply unit 607 of the in-vehicle T-BOX to supply power to the in-vehicle power consumption unit 602 of the vehicle. For example, the vehicle transmits the first indication signal to the power management unit 604 of the vehicle-mounted T-BOX through a physical path between the T-BOX of the vehicle-mounted T-BOX and the in-vehicle connector 603 via the T-BOX and the in-vehicle connector 603 and a signal line, so that the power management unit 604 controls the power supply unit 607 to supply power to the in-vehicle electric usage unit 602 through the external power supply circuit. For example, the power management unit 604 directly supplies the power of the power supply unit 607 to the in-vehicle electric unit 602 through an external power supply circuit via the T-BOX and the in-vehicle connector 603 as shown in fig. 6. Alternatively, the power management unit 604 may supply the power of the power supply unit 607 to the in-vehicle power unit 602 by an external power supply circuit via the T-BOX and the in-vehicle connector 603 and the in-vehicle power supply system 601.

For example, in the case that the power supply system in the vehicle cannot provide power supply due to an abnormality, it is assumed that the auxiliary device transmits the first indication signal to the vehicle-mounted T-BOX by using a wireless communication technology, and the wireless communication technology used is a 4G technology, and the auxiliary device is a mobile phone as an example. As shown in fig. 7, in the case that the power supply system 701 in the vehicle is abnormal and cannot supply power to the electric unit in the vehicle, the mobile phone may use 4G technology to send a first indication signal to the wireless communication and processing unit 705 of the vehicle-mounted T-BOX through the base station and the T-BOX antenna of the vehicle-mounted T-BOX to instruct the power supply unit 707 of the vehicle-mounted T-BOX to supply power to the electric unit 702 in the vehicle. After the wireless communication and processing unit 705 of the vehicle-mounted T-BOX receives the first indication signal, the first indication signal may be transmitted to the power management unit 704 of the vehicle-mounted T-BOX through a signal line. The power management unit 704 may control the power supply unit 707 to supply power to the in-vehicle electric usage unit 702 through an external power supply circuit. For example, the power management unit 704 supplies the power of the power supply unit 707 to the in-vehicle electric unit 702 through an external power supply circuit via the T-BOX and the in-vehicle connector 703 and the in-vehicle power supply system 701 as shown in fig. 7. Alternatively, the power management unit 704 may directly supply the power of the power supply unit 707 to the in-vehicle power unit 702 through an external power supply circuit via the T-BOX and the in-vehicle connector 703.

For example, when the power supply system in the vehicle is abnormal and cannot provide power supply, it is assumed that the auxiliary device sends the first indication signal to the vehicle-mounted T-BOX through a physical path, and the auxiliary device is a mobile phone as an example. As shown in fig. 8, in a case where the power supply system 801 in the vehicle is abnormal and cannot supply power to the electric unit in the vehicle, the mobile phone may send a first indication signal (the first indication signal is a hardware communication signal) to the T-BOX in the vehicle through a physical path between the T-BOX of the T-BOX in the vehicle and the mobile phone connector 808 (for example, the T-BOX and the mobile phone connector 808 may be a Universal Serial Bus (USB) interface), so as to indicate the power supply unit 807 of the T-BOX in the vehicle to supply power to the electric unit 802 in the vehicle. For example, the mobile phone sends the first indication signal to the power management unit 804 of the vehicle-mounted T-BOX through a physical path between the T-BOX of the vehicle-mounted T-BOX and the mobile phone connector 808 and a signal line via the T-BOX, the mobile phone connector 808 and the signal line, so that the power management unit 804 controls the power supply unit 807 to supply power to the vehicle-mounted electric unit 802 through an external power supply circuit. For example, the power management unit 804 supplies the power of the power supply unit 807 to the in-vehicle electric unit 802 through an external power supply circuit via the T-BOX and the in-vehicle connector 803 and the in-vehicle power supply system 801 as shown in fig. 8. Alternatively, the power management unit 804 may directly supply the power of the power supply unit 807 to the in-vehicle power unit 802 through an external power supply circuit via the T-BOX and the in-vehicle connector 803.

In the above scenario where the auxiliary device sends the first indication signal to the vehicle-mounted T-BOX, sending the first indication signal by the auxiliary device may be triggered by a user. For example, assuming that the auxiliary device is a mobile phone, a display interface of an application program of a vehicle-mounted T-BOX installed in the mobile phone is as shown in fig. 9, and when the power supply system in the vehicle cannot provide power supply, as shown in fig. 9, in the functional interface of the application program of the vehicle-mounted T-BOX, a user may click an "external power supply" button icon 901. After detecting the clicking operation of the user on the 'external power supply' button icon 901, the mobile phone responds to the clicking operation to send a first indication signal to the vehicle-mounted T-BOX so as to indicate a power supply unit of the vehicle-mounted T-BOX to supply power to an in-vehicle power utilization unit of the vehicle.

It should be noted that, in the case that the power supply system in the vehicle is abnormal and cannot provide power supply, the vehicle-mounted T-BOX may also control the power supply unit to provide power supply to the vehicle-mounted power utilization unit (e.g., the wireless communication and processing unit of the vehicle-mounted T-BOX and/or the T-BOX power utilization unit of the vehicle-mounted T-BOX), that is, the vehicle-mounted T-BOX will use the built-in power supply unit to provide power supply for operation. For example, as shown in fig. 3, when the power supply system 301 in the vehicle interior is abnormal and cannot supply power to the power consuming unit in the vehicle, the power supply unit 307 of the vehicle T-BOX can supply power to the bluetooth module 305 and the power consuming unit 306 of the vehicle T-BOX in addition to the power consuming unit 302 in the vehicle interior. For example, the power management unit 304 may convert the power provided by the power supply unit 307 into three power sources, where the first power source is output to the bluetooth module 305 of the vehicle-mounted T-BOX, the second power source is output to the T-BOX power utilization unit 306, and the third power source is output to the in-vehicle power utilization unit 302 through the external power supply circuit.

In addition, in the scenarios shown in fig. 4 to 8 in the embodiment of the present application, when the power supply system in the vehicle is abnormal and cannot provide power supply, the vehicle-mounted T-BOX may also use the built-in power supply unit to simultaneously provide power supply for the power consumption unit in the vehicle and the power consumption unit of the vehicle-mounted T-BOX itself, and the specific description thereof is similar to the corresponding description in the scenario shown in fig. 3 and is not repeated here. Under the condition that the in-vehicle power supply system of the vehicle can normally provide power supply, the in-vehicle power unit of the vehicle provides power supply for the in-vehicle T-BOX power supply circuit through the in-vehicle power supply system, and the specific description is similar to that of the scenario shown in fig. 1, and is not repeated here.

Furthermore, in order to save the electric quantity of the vehicle-mounted T-BOX power supply unit, the external power supply circuit is in a disconnection state by default, and when the power supply unit of the vehicle-mounted T-BOX needs to supply power to the vehicle internal power utilization unit of the vehicle, the external power supply circuit is conducted. That is, as shown in fig. 10, before S202, the power supply method may further include:

s203, the vehicle-mounted T-BOX controls the conduction of an external power supply circuit.

Wherein, after the vehicle-mounted T-BOX receives the first indication signal, the power supply unit of the vehicle-mounted T-BOX needs to supply power to the vehicle interior electric unit of the vehicle. The vehicle-mounted T-BOX may control the external power supply circuit to be turned on, and specifically, the vehicle-mounted T-BOX may convert a switching signal of a power supply switch of the external power supply circuit from a first level to a second level, for example, convert a switching signal of a power supply switch of the external power supply circuit from a low level to a high level to control the external power supply circuit to be turned on. Thus, the vehicle-mounted T-BOX can control the power supply unit to supply power to the vehicle-mounted electric unit through the external power supply circuit.

For example, referring to fig. 3, the external power supply circuit is a power supply path from a power management unit 304 of the vehicle-mounted T-BOX to an in-vehicle power supply system 301 of the vehicle via the T-BOX of the vehicle-mounted T-BOX and an in-vehicle connector 303. Alternatively, as shown in fig. 4, the external power supply circuit may be a power supply path from the power management unit 304 of the vehicle-mounted T-BOX to the in-vehicle power unit 302 of the vehicle via the T-BOX of the vehicle-mounted T-BOX and the in-vehicle connector 303. For another example, referring to fig. 5, the external power supply circuit is a power supply path from a power management unit 504 of the vehicle-mounted T-BOX to an in-vehicle power supply system 501 of the vehicle via the T-BOX of the vehicle-mounted T-BOX and an in-vehicle connector 503. Alternatively, as shown in fig. 6, the external power supply circuit may be a power supply path from the power management unit 604 of the vehicle-mounted T-BOX to the in-vehicle electric unit 602 of the vehicle via the T-BOX of the vehicle-mounted T-BOX and the in-vehicle connector 603. The external power supply circuit in fig. 7 and 8 is similar to the external power supply circuit in fig. 5.

Further, after the end of supplying power to the in-vehicle electrical unit through the external power supply circuit by the vehicle-mounted T-BOX, as shown in fig. 11, the power supply method may further include:

and S204, the vehicle-mounted T-BOX receives a second indication signal, and the second indication signal is used for indicating the power supply unit to stop supplying power to the in-vehicle electric unit.

For example, when the in-vehicle power supply system of the vehicle returns to normal, or the emergency handling of the user is completed (e.g., the engine of the vehicle is successfully ignited, the door of the vehicle is successfully opened, etc.), the vehicle or the auxiliary device may transmit a second indication signal for indicating the power supply unit to stop supplying power to the in-vehicle power consumption unit to the vehicle-mounted T-BOX.

It should be noted that, in the embodiment of the present application, an implementation process of sending the second indication signal to the vehicle-mounted T-BOX by the vehicle or the auxiliary device is similar to an implementation process of sending the first indication signal to the vehicle-mounted T-BOX by the vehicle or the auxiliary device in the embodiment of the present application, and for a specific description that the vehicle or the auxiliary device sends the second indication signal to the vehicle-mounted T-BOX, reference may be made to a specific description that the vehicle or the auxiliary device sends the first indication signal to the vehicle-mounted T-BOX in the embodiment of the present application, and details of the embodiment of the present application are not repeated here.

And S205, controlling the power supply unit to stop supplying power to the in-vehicle electric unit by the vehicle-mounted T-BOX according to the second indication signal.

Wherein, after the vehicle-mounted T-BOX receives the second indication signal, the power supply unit of the vehicle-mounted T-BOX is required to stop the power supply to the vehicle interior electricity utilization unit of the vehicle. The vehicle-mounted T-BOX can control the power supply unit to stop supplying power to the power utilization unit in the vehicle according to the second indication signal. That is to say, the vehicle-mounted T-BOX may control the external power supply circuit to be disconnected according to the second indication signal, specifically, the switching signal of the power supply switch of the external power supply circuit may be converted from the second level to the first level, for example, the switching signal of the power supply switch of the external power supply circuit is converted from the high level to the low level to control the external power supply circuit to be disconnected, so as to save the electric quantity of the vehicle-mounted T-BOX power supply unit.

In the scenario that the auxiliary device sends the second indication signal to the vehicle-mounted T-BOX, sending the second indication signal by the auxiliary device may also be triggered by the user. For example, assuming that the auxiliary device is a mobile phone, when the in-vehicle power supply system of the vehicle returns to normal, or the emergency handling of the user is completed, as shown in fig. 12, in the functional interface of the application program of the in-vehicle T-BOX, the user may click an "external power supply" button icon 1201. After detecting the clicking operation of the user on the 'external power supply' button icon 1201, the mobile phone responds to the clicking operation and sends a second indication signal to the vehicle-mounted T-BOX so as to indicate a power supply unit of the vehicle-mounted T-BOX to supply power to an in-vehicle power utilization unit of the vehicle.

To facilitate understanding by those skilled in the art, the power supply method provided by the embodiments of the present application is exemplified herein. For example, the vehicle establishes a Bluetooth connection with the onboard T-BOX. Referring to fig. 3, when an abnormality occurs in an in-vehicle power supply system 301 of a vehicle and power cannot be supplied to an ignition system of an engine of the vehicle, a user may trigger a corresponding button in the vehicle so that a bluetooth module 308 of the vehicle sends a first indication signal to a bluetooth module 305 of an in-vehicle T-BOX using a bluetooth protocol to indicate a power supply unit 307 of the in-vehicle T-BOX to supply power to the ignition system of the engine of the vehicle. After receiving the first indication signal, the bluetooth module 305 of the vehicle-mounted T-BOX sends the first indication signal to the power management unit 304 of the vehicle-mounted T-BOX through a signal line. The power management unit 304 controls conduction to the external power supply circuit, and controls the power supply unit 307 to supply power to the ignition system of the vehicle engine through the external power supply circuit with the in-vehicle connector 303 and the in-vehicle power supply system 301 via the T-BOX. Further, after the engine of the vehicle is successfully ignited, the bluetooth module 308 of the vehicle sends a second indication signal to the bluetooth module 305 of the vehicle-mounted T-BOX by using the bluetooth protocol to instruct the power supply unit 307 of the vehicle-mounted T-BOX to stop supplying power to the ignition system of the engine of the vehicle. The bluetooth module 305 of the vehicle-mounted T-BOX receives the second indication signal and transmits the second indication signal to the power management unit 304 of the vehicle-mounted T-BOX through a signal line. The power management unit 304 controls the disconnection of the external power supply circuit. Under the condition that the power supply system in the vehicle is abnormal, a user can also carry out power supply ignition on the engine of the vehicle, so that the emergency requirement is met.

According to the power supply method provided by the embodiment of the application, when the power supply system in the vehicle is abnormal and cannot provide power supply, the vehicle-mounted T-BOX receives an indication signal for indicating the power supply unit of the vehicle-mounted T-BOX to provide power supply for the power utilization unit in the vehicle, and the vehicle-mounted T-BOX controls the power supply unit to provide power supply for the power utilization unit in the vehicle through the external power supply circuit according to the received indication signal. The problem of can't realize providing the power supply for the interior power consumption unit of car when power supply system appears unusually in the car is solved to satisfy user's urgent demand. And the state of the external power supply circuit is defaulted to be an off state, and the power supply circuit is switched on when power supply needs to be provided for the vehicle-mounted power utilization unit, so that the electric quantity of the vehicle-mounted T-BOX power supply unit is saved.
