Fig. 2 shows a power supply distribution apparatus 2000 for an in-vehicle control device according to an embodiment of the present invention.
The power distribution apparatus 2000 comprises a first conditioning device 210, a second conditioning device 220, a first control device 230 and a power interface 241 and a power interface 242. Wherein the first conditioning device 210 conditions the received power and outputs the conditioned power to the first control device 230 upon receiving the power from the power source 250. The second conditioning device 220 receives electric power from the power source 250, conditions the received electric power, and outputs the conditioned electric power to the second control device a 261 and the second control device B262 outside the in-vehicle power distribution apparatus via the two electric power interfaces 241, 242, respectively.
In one embodiment, the power distribution apparatus 2000 may be disposed on a motherboard, the first control device 230 may be a main control chip on the motherboard, and the second control device a 261 and the second control device B262 may be two on-board domain controllers connected to the motherboard, respectively.
Thus, the main control chip (i.e., the first control device 230) on the main board can be decoupled from the domain controllers (i.e., the second control device a 261 and the second control device B262) connected to the main board through the power distribution device 2000, and the mode of independent power supply of the main board and the domain controllers is adopted, so that the chip and the domain controllers on the main board can acquire electric energy from the power supply through different conditioning circuits respectively. When the domain controller fails (e.g., shorts), power to the chip on the motherboard is not affected. In addition, the power distribution apparatus 2000 directly processes the power from the power source on the main board and then provides the power to the domain controller, so that the repeated development devices of the domain controller can be effectively reduced. Moreover, since the conditioning devices are often large in size, the unified arrangement of the conditioning devices on the power distribution apparatus 2000 can also effectively reduce the size of the domain controller.
In one embodiment according to the present invention, the power distribution apparatus 2000 may further include a first power management device 260, a communication interface a, and a communication interface B (not shown in fig. 2). The first power management device 260 is configured to receive power information about the first control device 230 from the first control device 230, power information about the second control device a 261 via the communication interface a, and power information about the second control device B262 via the communication interface B. The first power management device 260 is further configured to monitor the power state of the first control device 230, the power state of the second control device a 261, and the power state of the second control device B262 based on the received power information about the first control device 230, the power information about the second control device a 261, and the power information about the second control device B262.
By providing the power distribution apparatus 2000 with the first power management device 260, it can be ensured that the first control device 230 on the motherboard can still send and receive commands normally when the second control device a 261 and the second control device B262 fail. In addition, by providing the power supply distribution apparatus 2000 with a communication interface, the state information of the second control device a 261 and the second control device B262 can be fed back to the power supply distribution apparatus 2000 in real time, so that real-time monitoring and unified management of each control device can be realized.
Although not shown in fig. 2, in one embodiment according to the present invention, the power distribution apparatus 2000 may receive power from two or more power sources. This is because, according to the failure rate statistics, the failure rate of the chip or the control device is lower than the failure rate of the battery or the power supply, so that two or more power supplies are used to supply power to the power distribution device 2000, which can compensate the problem of power failure to some extent, and provide a standby power supply for the system.
Since the output voltages of two or more power sources are difficult to be identical, there may be a problem of current reverse flow in the power distribution apparatus 2000. To this end, the power distribution apparatus 2000 may further comprise a first anti-reflection device 271 and a second anti-reflection device 272. The first anti-reflection device 271 is disposed between the power supply 250 and the first control device 230, and the second anti-reflection device 272 is disposed between the power supply 250 and the power interfaces 241, 242 for preventing reverse current transmission.
In one embodiment according to the present invention, the power distribution apparatus 2000 may further comprise a first adjustable protection device 281 and a second adjustable protection device 282 to provide protection, e.g. over-current protection, over-voltage protection, over-power protection, etc., for the second control device a 261 and the second control device B262, respectively. Since the parameters of the second control means a 261 and the second control means B262 may not be identical (e.g. have different powers, respectively), they are respectively provided with adjustable protection means, so that the power distribution device 2000 can flexibly provide protection for the second control means (i.e. the domain controller) of different parameters.
Although not shown in fig. 2, in one embodiment according to the present invention, the power distribution apparatus 2000 may further include a third control device. The third control device may receive the electric energy conditioned by the first conditioning device 210 via the first anti-reflection device 271. The third control means may be, for example, a peripheral chip on the motherboard. The power state of the third control device may be monitored by the first power management device 260 or by another power management device.
Alternatively, the output power of the power interfaces 241, 242 is calculated according to the rated power of the domain controller (i.e. the second control means) to be connected to the power distribution device 2000, e.g. 30W of output power is reserved for the power interfaces 241, 242, respectively.
Optionally, the power distribution apparatus 2000 further includes an AD sampling path to monitor the power status of the second control devices 261, 262 while feeding back the power information of the second control devices 261, 262 to the power distribution apparatus 2000 through the above-mentioned communication interfaces a and B.
The power distribution apparatus 2000 and the second control device (e.g., the second control devices 261, 262) described above may be included in a power distribution system according to an embodiment of the present invention. It is noted that the number of power interfaces and communication interfaces in the power distribution apparatus 2000 may be higher than the number of second controls, thereby reserving some interfaces for the power distribution system as spares so that the power distribution system may be extended access to more second control devices (e.g., domain controllers) when needed.
The second control device of the power supply distribution system can comprise an independent power management device for providing independent power management for the second control device, so that the electric energy health state of the whole power supply distribution system is further improved.
A power supply may also be included in the power distribution system for providing electrical power to the various control devices in the power distribution system. Optionally, the power distribution system includes two or more power sources, so that when a single power source fails, the control devices in the power distribution system can obtain electric energy from other power sources without affecting the normal operation of the control devices.
Those skilled in the art will readily appreciate that the power distribution system according to embodiments of the present invention can be incorporated into a vehicle, wherein the first control means can be any suitable master controller in the vehicle, e.g. a respective electronic control unit ECU, a system on chip SOC, etc., and the second control means can be any suitable controller in the vehicle, e.g. various domain controllers.
In summary, the power distribution apparatus for an in-vehicle control device according to an aspect of the present invention provides a main controller and a domain controller connected to the power supply apparatus with mutually decoupled power supply paths, so that the main controller and the domain controller respectively obtain electric energy from a power supply through different conditioning circuits. When the domain controller fails, the power supply of the main controller is not affected. In addition, the power supply distribution equipment directly processes the electric energy from the power supply on the main board and then provides the electric energy for the domain controller, so that repeated development devices of the domain controller can be effectively reduced, and the volume of the domain controller is effectively reduced.
The power distribution apparatus for an in-vehicle control device according to an aspect of the present invention sets a communication interface for each domain controller so that each domain controller can directly communicate with the power distribution apparatus, thereby enabling real-time feedback of power status information of each domain controller into the power distribution apparatus.
According to the power supply distribution equipment for the vehicle-mounted control device, provided by the invention, a power supply distribution scheme with higher universality, better expansibility and better robustness performance can be provided for the vehicle-mounted control device.
Although only a few embodiments of the present invention have been described above, those skilled in the art will appreciate that the present invention can be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and the invention is intended to cover various modifications and substitutions without departing from the spirit and scope of the invention as defined by the appended claims.
