Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the control method, device and vehicle for automatic parking provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The application scenario includes a Vehicle provided with a VCU (Vehicle Control Unit, chinese) for controlling the gears of the Vehicle to switch. The vehicle may be an automobile, which is not limited to a conventional automobile, a pure electric automobile or a hybrid automobile, but may also be applicable to other types of motor vehicles or non-motor vehicles.
Fig. 1 is a flowchart illustrating a control method of automatic parking according to an exemplary embodiment. As shown in fig. 1, the method comprises the steps of:
And 102, if the vehicle is determined to meet the parking condition, determining the state of a parking device of the vehicle.
For example, when the vehicle is in a stationary state, if the driver does not shift the gear of the vehicle to the parking gear, the vehicle is likely to roll. In order to avoid the vehicle from slipping, the VCU may determine whether the vehicle satisfies a preset parking condition when the gear of the vehicle is any one of a reverse gear (i.e., R gear), a neutral gear (i.e., N gear), and a forward gear (i.e., D gear) and the vehicle is in a stationary state. The parking condition is a condition which is required to be met by the vehicle when the vehicle needs to be automatically parked according to the actual scene that the vehicle possibly slides. If the vehicle is determined to meet the parking condition, and the state of the parking device of the vehicle is determined through the VCU, the parking device can lock the motor of the vehicle (the parking device can lock the motor of the vehicle, for example, the parking device can mechanically lock an output shaft of a transmission of the vehicle), and therefore the vehicle can be parked.
For example, the actual scene of vehicle slipping can be divided into the following cases:
1) when the driver unlocks the vehicle (at the moment, the power mode of the vehicle is switched from the ON mode to the OFF mode), the preset condition can be set to be that if the power mode of the vehicle is switched from the ON mode to the OFF mode, the vehicle is determined to meet the parking condition. The ON mode is a low-voltage power-ON mode, when the power mode is the ON mode, the power supply of a low-voltage electric appliance in the vehicle is in an ON state, the OFF mode is a power-OFF mode, and when the power mode is the OFF mode, the power supply of the vehicle is in an OFF state.
2) After the driver starts the engine (at this time, the power mode of the vehicle is Ready mode), the door on the driving position side is opened, and the preset condition may be set to be that if the power mode of the vehicle is Ready mode and the target door of the vehicle is in an open state, it is determined that the vehicle meets the parking condition, where the Ready mode is a high-voltage power-on mode, and when the power mode is Ready mode, the high-voltage circuit of the vehicle is turned on, and the target door may be the door on the driving position side or another door on the vehicle.
3) When the driver stops the vehicle and charges the vehicle through the charging device by using an alternating current or direct current charging wire (at this time, the power mode of the vehicle is an ON mode), the preset condition may be set to be that if the power mode of the vehicle is the ON mode, and the vehicle is connected with the charging device, it is determined that the vehicle meets the parking condition, and the charging device may be an alternating current charging pile, for example.
4) When the power mode of the vehicle is switched from the OFF mode to the ON mode during the running of the vehicle (the switching of the power mode from the OFF mode to the ON mode may occur only when an abnormality occurs in the vehicle), the preset condition may be set to determine that the vehicle satisfies the parking condition if the vehicle is in a running state and the power mode of the vehicle is switched from the OFF mode to the ON mode.
And 103, unloading the torque of the motor of the vehicle if the state of the parking device is a normal state.
And 104, switching the gear to the parking gear after the torque unloading of the motor is finished so as to park the parking device.
Specifically, if the state of the parking device is a normal state, the parking device can operate normally at this time. When the torque output from the motor of the vehicle is large, the vehicle may move again, and if the shift position of the vehicle is directly switched to the parking position at this time, the parking device may be damaged. In order to avoid damage to the parking device, after determining that the state of the parking device is a normal state, torque unloading (i.e., reducing the torque output by the motor below a certain threshold) is performed by controlling the motor through the VCU. After the torque unloading of the motor is finished, the gear of the vehicle is controlled to be switched to a parking gear through the VCU, and the motor of the vehicle is locked by the parking device, so that the vehicle is parked.
In summary, according to the present disclosure, when the shift position of the vehicle is not the parking position and the vehicle is in the stationary state, it is determined whether the vehicle meets a preset parking condition, when it is determined that the vehicle meets the parking condition, a state of a parking device of the vehicle is determined, if the state of the parking device is a normal state, a torque of a motor of the vehicle is unloaded, and after the torque unloading of the motor is completed, the shift position is switched to the parking position, so that the parking device parks the vehicle. This openly can be when the driver forgets to switch the fender position of vehicle to the parking fender, automatic with the fender position of vehicle switch to the parking fender, ensure that the vehicle is in the parking state, prevent that the vehicle from taking place the swift current car, realize simply, improved the degree of safety of vehicle.
Fig. 2 is a flowchart illustrating another control method of automatic parking according to an exemplary embodiment. As shown in fig. 2, after step 103, the method further comprises:
and 105, after the first preset time, acquiring the torque of the motor, and if the torque is smaller than or equal to a preset torque threshold, determining that the torque unloading of the motor is finished.
And 106, if the torque is larger than a preset torque threshold value, switching the gear to the neutral gear, and sending a prompt message, wherein the prompt message is used for prompting that the gear is not switched to the parking gear.
For example, in order to ensure that the torque of the motor can be successfully unloaded, the VCU may obtain the torque of the motor after a first preset time, and determine a magnitude relationship between the torque of the motor and a preset torque threshold, where if the torque of the motor is less than or equal to the preset torque threshold, it is indicated that the unloading of the torque of the motor is completed within the first preset time. If the torque is larger than the preset torque threshold, it is indicated that the torque of the motor is not successfully unloaded within the first preset time, the gear of the vehicle can be controlled to be switched to the neutral gear through the VCU, and a prompt message for prompting a driver that the gear of the vehicle is not switched to the parking gear is sent. The manner of sending the prompt information may be to control a speaker of the vehicle to send an audio prompt, or to control a lamp of the vehicle to flash in a preset manner (for example, to control the lamp to flash in a preset frequency), or to display the audio prompt on a central control display screen of the vehicle in an image manner. Further, when the VCU determines that the torque of the motor is greater than the preset torque threshold, the VCU may repeatedly execute the steps 102 to 106 in a first preset period, and if the torque of the motor is unloaded in the first preset period, the VCU may control the shift position of the vehicle to be switched to the parking position, and the parking device locks the motor of the vehicle, so that the vehicle is parked. If the torque of the motor is still not successfully unloaded in the first preset period, the gear of the vehicle can be controlled to be switched to the neutral gear through the VCU, and prompt information is sent.
Fig. 3 is a flow chart illustrating another control method of automatic parking according to an exemplary embodiment. As shown in fig. 3, after step 104, the method further comprises the steps of:
and step 107, after a second preset time, if the gear is not the parking gear, switching the gear to the neutral gear, and sending a prompt message, wherein the prompt message is used for prompting that the gear is not switched to the parking gear.
In one scenario, during the process that the VCU controls the gear of the vehicle to be switched to the parking gear, a situation that the gear is not successfully switched may occur, and in order to avoid that the driver mistakenly believes that the vehicle has been successfully parked, whether the gear of the vehicle is switched to the parking gear may be detected by the VCU after a second preset time. If the gear of the vehicle is the parking gear, the VCU does not perform any operation, and if the gear of the vehicle is not the parking gear, the VCU can control the gear of the vehicle to be switched to the neutral gear and send a prompt message for prompting a driver that the gear of the vehicle is not switched to the parking gear. The manner of sending the prompt information may be to control a speaker of the vehicle to send an audio prompt, or to control a lamp of the vehicle to flash in a preset manner (for example, to control the lamp to flash in a preset frequency), or to display the audio prompt on a central control display screen of the vehicle in an image manner.
Fig. 4 is a flowchart illustrating still another control method of automatic parking according to an exemplary embodiment. As shown in fig. 4, the method further comprises the steps of:
and step 108, if the state of the parking device is an abnormal state, switching the gear to the neutral gear, and sending a prompt message, wherein the prompt message is used for prompting that the gear is not switched to the parking gear.
In another scenario, if the state of the parking device is an abnormal state, it is indicated that the parking device cannot work normally, that is, the parking device cannot park the vehicle, the VCU may control the gear of the vehicle to switch to the neutral gear, and send a prompt message for prompting the driver that the gear of the vehicle is not switched to the parking gear. The manner of sending the prompt information may be to control a speaker of the vehicle to send an audio prompt, or to control a lamp of the vehicle to flash in a preset manner (for example, to control the lamp to flash in a preset frequency), or to display the audio prompt on a central control display screen of the vehicle in an image manner. Further, when the VCU determines that the state of the parking device is an abnormal state, the step 102 may be repeatedly executed by the VCU in a second preset period, and if the VCU detects that the state of the parking device is a normal state in the second preset period, the VCU may control the motor to unload the torque, and after the torque unloading of the motor is completed, the VCU may control the gear of the vehicle to be switched to the parking gear. If the VCU detects that the state of the parking device is always an abnormal state in a second preset period, the VCU can control the gear of the vehicle to be switched to the neutral gear and send prompt information.
It should be noted that the prompt information may be displayed in a form of sound, light, or image all the time, or may be stopped being displayed after a preset condition is met. For example, the VCU may further detect whether the driver manually switches the shift range of the vehicle to the parking range, and stop displaying the prompt message if it is detected that the driver manually switches the shift range of the vehicle to the parking range.
In summary, according to the present disclosure, when the shift position of the vehicle is not the parking position and the vehicle is in the stationary state, it is determined whether the vehicle meets a preset parking condition, when it is determined that the vehicle meets the parking condition, a state of a parking device of the vehicle is determined, if the state of the parking device is a normal state, a torque of a motor of the vehicle is unloaded, and after the torque unloading of the motor is completed, the shift position is switched to the parking position, so that the parking device parks the vehicle. This openly can be when the driver forgets to switch the fender position of vehicle to the parking fender, automatic with the fender position of vehicle switch to the parking fender, ensure that the vehicle is in the parking state, prevent that the vehicle from taking place the swift current car, realize simply, improved the degree of safety of vehicle.
