[0021] As briefly mentioned earlier, the development of next-generation digital technologies such as artificial intelligence, the Internet of Things, and 5G communication in recent years has provided strong support for autonomous driving technology. Autonomous driving technology utilizes sensors, computer vision, machine learning, and other technologies to achieve autonomous navigation, obstacle avoidance, acceleration, and deceleration of vehicles without human driver intervention. However, traditional autonomous vehicles have limited interaction between controllers, making it impossible to manage power according to the characteristics of the autonomous driving system, thus affecting the efficiency and accuracy of vehicle power management.

[0022] Therefore, embodiments of this disclosure propose a scheme for power system management of a vehicle. According to various embodiments of this disclosure, the vehicle interface module first activates the vehicle's autonomous driving control module, and then receives first reference information from the autonomous driving control module, the first reference information indicating, for example, the state of at least one component of the vehicle associated with the autonomous driving control module. The vehicle interface module then determines activation information regarding the at least one component of the vehicle based on the reference information.

[0023] In this way, the embodiments of this disclosure can manage the vehicle's power system more efficiently and accurately.

[0024] Example embodiments of this disclosure are described below with reference to the accompanying drawings.

[0025] Example Environment

[0026] Figure 1 shows a schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented. As shown in Figure 1, environment 100 includes a vehicle interface module (VIM) 110, an autonomous driving system 120, and a vehicle infrastructure system 130.

[0027] In some implementations, the vehicle interface module 110 is communicatively connected to both the autonomous driving system and the vehicle infrastructure system 130. For example, the vehicle interface module 110 can receive an ignition signal from the vehicle infrastructure system 130 and, based on the ignition signal, start multiple modules associated with the autonomous driving system 120 in a preset startup sequence.

[0028] The autonomous driving system 120 may include multiple sensors and an autonomous driving control module (ACU). The vehicle infrastructure system 130 may include a body domain control module, a cockpit domain control module, a braking module, a steering module, and a drive module.

[0029] In some implementations, the vehicle interface module 110 can be implemented as a gateway for communication between the autonomous driving computer and various vehicle control systems. The vehicle interface module 110 can perform trajectory management and trajectory tracking.

[0030] It should be understood that the structure and function of the various elements in environment 100 are described for illustrative purposes only and do not imply any limitation on the scope of this disclosure.

[0031] The following description will continue with reference to the accompanying drawings, which will provide some exemplary embodiments of this disclosure.

[0032] Example process

[0033] Figure 2 shows a flowchart of a process 200 for managing the power system of a vehicle according to some embodiments of the present disclosure. Process 200 can be implemented at the vehicle interface module 110. Process 200 will now be described with reference to Figure 1.

[0034] As shown in Figure 2, in block 210, the vehicle interface module 110 activates the vehicle's autonomous driving control module 330. In some embodiments, after receiving a voltage indication signal 373 from the vehicle's base vehicle controller, the vehicle interface module 110 can send a start signal to the autonomous driving module 330. The voltage indication signal 373 indicates that the output voltage of the vehicle's power conversion module meets a threshold voltage.

[0035] As an example, Figure 3 illustrates a power supply timing 300 for power management according to an embodiment of this disclosure. After receiving a voltage indication signal 373 from the base vehicle controller, the vehicle interface module 110 can send a first power-on signal 374 to the power supply module 310 based on the voltage indication signal 373, instructing the power supply module 310 to perform power distribution 375 to the autonomous driving control module 330. Once the autonomous driving control module 330 is powered on, it wakes itself up to complete the startup process.

[0036] In some embodiments, during the process of activating at least one component of the vehicle by the vehicle interface module 110, power supply (i.e., power distribution), wake-up, and / or other appropriate operations may be performed on at least one component associated with the vehicle. The vehicle component may, for example, include the vehicle's control module, at least one device associated with the control module, and so on.

[0037] The vehicle interface module 110 can also send a first power-on signal 374 to the power supply module 310. In some embodiments, as shown in FIG3, after receiving the first power-on signal 374, the power supply module 310 can perform power distribution 375 to the temperature control module 320. This wakes up the temperature control module 320, thus completing its startup. In some embodiments, after the temperature control module 320 starts working, it can adjust the temperature of the autonomous driving control module based on the vehicle's current temperature.

[0038] In some scenarios, after the temperature control module 320 is activated, the vehicle interface module 110 can receive a self-test signal from the temperature control module 320. This self-test signal indicates the device status of the controllers and actuators associated with the temperature control module 320. Furthermore, the vehicle interface module 110 can determine the operating status of at least one of the controllers and actuators indicated by the self-test signal based on the signal. When at least one of the controllers and actuators is in an abnormal state, the vehicle interface module 110 can disconnect the power supply to the controllers and actuators associated with the temperature control module 320. In this way, when there is equipment in an abnormal state in the vehicle, the power supply to the equipment can be disconnected in a timely manner, thereby effectively improving the safety of the vehicle startup process.

[0039] In addition, the power supply module 310 can sequentially distribute power to the autonomous driving control module 330 and the cockpit domain control module 340 via power distribution modules 376 and 377.

[0040] When starting the autonomous driving control module 330, its temperature typically needs to meet a threshold temperature for successful startup. In some scenarios, to improve vehicle startup efficiency, the vehicle interface module 110 can prioritize starting the temperature control module 320 after receiving a voltage indication signal. Once the temperature control module 320 is operational, it can adjust the temperature of the autonomous driving control module 330. When the temperature of the autonomous driving control module 330 is within a preset range, the vehicle interface module 110 then instructs the power supply module 310 to distribute power to the autonomous driving control module 330 (376) to wake it up. This method reduces the number of times the autonomous driving module 330 needs to be started, thereby improving vehicle startup efficiency.

[0041] Optionally, in some embodiments, as shown in FIG3, the power supply module 310 may also be started before the vehicle's autonomous driving control module 330 is started. The vehicle interface module 110 may receive an ignition signal 371 sent by the base vehicle controller 360, thereby enabling its start. The vehicle interface module 110 may send an ignition signal 372 to the power supply module 310 to start the power supply module 310.

[0042] Referring again to Figure 2, in block 220, the vehicle interface module 110 receives first reference information 378 from the autonomous driving control module 330. The first reference information 378 includes status information fed back from the autonomous driving control module 330 to the vehicle interface module 110, which may, for example, indicate the status of at least one component (e.g., one or more first devices 335) associated with the autonomous driving control module 330 in the vehicle. The first reference information 378 may, for example, indicate that the control unit in the autonomous driving control module 330 has been activated and that the graphics processing unit in the autonomous driving module 330 is in an enableable state. The first device 335 may be a component, module, or device controlled or communicatively connected to the autonomous driving control module 330, such as, but not limited to, LiDAR, microwave radar (e.g., millimeter-wave radar), ultrasonic radar, and sensors.

[0043] Referring again to Figure 2, in box 230, the vehicle interface module 110 activates at least one component based on the first reference information 378. As an example, as shown in Figure 3, after receiving the first reference information 378, the vehicle interface module 110 can send a wake-up signal 379 to the power supply module 310 to wake up the power supply controller in the power supply module 310. During the power-on process, the various modules of the vehicle can fully interact with the vehicle interface module 110, enabling the vehicle interface module 110 to control the power supply based on the state of at least one controller. In this way, the safety and efficiency of vehicle startup can be effectively improved.

[0044] In some embodiments, as shown in FIG3, after receiving the first reference information 378, the vehicle interface module 110 can send a wake-up signal 380 to the autonomous driving control module 330 to wake up the graphics processing unit in the autonomous driving control module 330. In some scenarios, after the autonomous driving control module 330 receives the wake-up signal 380, the autonomous driving control module 330 can detect its internal temperature. When the internal temperature of the autonomous driving control module 330 meets a preset temperature, the autonomous driving control module 330 can wake up its internal graphics processing unit.

[0045] In some embodiments, the vehicle interface module 110 can activate the cockpit domain control module 340 based on the received first reference information 378. Specifically, if the first reference information 378 indicates, or if it can be determined based on the first reference information 378, that the control unit in the autonomous driving control module 330 has been activated, the vehicle interface module 110 can activate the cockpit domain control module 340. As an example, as shown in FIG3, the vehicle interface module 110 can receive the first reference information 378. After receiving the first reference information 378, the vehicle interface module 110 can send a wake-up signal 381 to the cockpit domain control module 340. After receiving the wake-up signal 381, the cockpit domain control module 340 is activated by the vehicle interface module 110, thereby completing the activation of the cockpit domain control module 340.

[0046] As an example, as shown in FIG3, after the vehicle interface module 110 starts the autonomous driving control module 330, it can receive multiple reference messages from different modules. In some embodiments, in addition to the first reference message 378 from the autonomous driving control module 330, the vehicle interface module 110 can also receive a second reference message 382 from the cockpit domain control module 340. The second reference message 382 may, for example, indicate that the cockpit domain control module 340 has been started and that at least one second device 345 is in a startable state. Further, the vehicle interface module 110 can send a start signal to the cockpit domain control module 340 based on the second reference message 382 to start at least one second device 345.

[0047] After receiving the second reference information 382, ​​the vehicle interface module 11O can send a second power-on signal 384 to the power supply module 310. The power supply module 310 can then perform power distribution 385 to the second device 345 (e.g., but not limited to display devices and / or power amplifier devices).

[0048] Optionally, in some embodiments, as shown in FIG3, when the graphics processing unit in the autonomous driving control module 330 is activated, the autonomous driving control module 330 can send graphics processing unit activation information 386-1 to the vehicle interface module 110, for example as part of the first reference information 387. Thus, the vehicle interface module 110 can obtain the status of the device associated with the autonomous driving control module 330.

[0049] Furthermore, the autonomous driving control module 330 can also send a graphics processing unit wake-up message 386-2 to the cockpit domain control module 340. Upon receiving the graphics processing unit wake-up message 386-2, the cockpit domain control module 340 can perform a hard-wired wake-up 388 on the second device 345 to complete its startup. Pre-starting the display and amplifier devices before the vehicle is fully started allows the user to perceive the vehicle's startup in advance, thereby improving the user's driving experience.

[0050] In some scenarios, after the cockpit domain control module 340 is activated, it can detect the identifier of a second device 345 that can be activated. After the cockpit domain control module 340 receives the graphics processing unit activation information 386-2 from the autopilot control module 330, it can activate the corresponding second device 345 based on the detected identifier of the second device 345 that can be activated, such as activating a display device or a power amplifier device.

[0051] In some embodiments, the vehicle interface module 110 may activate one or more first devices 335 associated with the autonomous driving control module 330 based on the first reference information 378. Specifically, if the first reference information 378 indicates that the image processing unit in the autonomous driving control module 330 has been activated and one or more first devices 335 are in an activatable state, the vehicle interface module 110 may activate one or more first devices 335, such as, but not limited to, LiDAR, microwave radar (e.g., radar operating in the millimeter-wave band), ultrasonic radar (which emits ultrasonic waves through an ultrasonic transmitter and receives the reflected ultrasonic waves using a receiver), sensors, etc. Sensors may include, for example, but are not limited to, cameras, pressure sensors, temperature sensors, wheel speed sensors, etc.

[0052] As an example, as shown in Figure 3, the vehicle interface module 110 can receive first reference information 387 sent by the autonomous driving module 330. The first reference information 387 indicates that the image processing unit in the autonomous driving module has been awakened, and one or more first devices 335 are in a startable state. After receiving the first reference information 387, the vehicle interface module 110 can send a third power-on signal 389 to the power supply module 310. Further, after receiving the third power-on signal 389, the power supply module 310 can perform power distribution 390 to the first devices 335, thereby waking up the first devices 335. In this way, the startup of the first devices 335 can be completed.

[0053] In some scenarios, after the autonomous driving control module 330 is activated, it can detect the identifier of the first device 335 that can be activated. Further, the autonomous driving control module 330 can generate first reference information 387 based on the detected identifier of the first device 335 that can be activated. Finally, when the vehicle interface module 110 receives the first reference information 387, it can activate the corresponding first device 335 based on the first reference information 387.

[0054] Optionally, in some embodiments, after receiving the vehicle status signal 391, the vehicle interface module 110 may send a fourth power-on signal 392 to the power supply module 310. Upon receiving the fourth power-on signal 392, the power supply module 310 may perform power distribution 393 from one or more other devices besides the first device 335 and the second device 345 (also referred to as a third device 350 associated with the vehicle) to activate the third device 350. The third device 350 may, for example, be another control module in the autonomous driving domain.

[0055] In addition to the power-on process discussed above, embodiments of this disclosure also provide a power-off process, namely, a power-off process controlled by the vehicle interface module 110. As an example, FIG4 illustrates a power-off timing 400 of power management according to an embodiment of this disclosure.

[0056] In some embodiments, the vehicle interface module 110 may stop supplying power to various modules and components associated with the vehicle based on a sleep signal 401 from the vehicle's base vehicle controller. On one hand, the vehicle interface module 110 may stop supplying power to one or more first devices 335 associated with the autonomous driving module 330 based on a sleep signal 401 from the vehicle's base vehicle controller 360. On the other hand, the vehicle interface module 110 may stop supplying power to one or more second devices 345 associated with the cockpit domain control module 340 based on a sleep signal 401 from the vehicle's base vehicle controller.

[0057] As an example, as shown in Figure 4, after receiving a sleep signal 401 from the basic vehicle controller 360, the vehicle interface module 110 can send a first power-off signal 402 to the power supply module 310. The power supply module 310 can then stop supplying power to the first device 335, the second device 345, and the third device 350 respectively (403, 404, and 405) to shut down these devices. In this way, by prioritizing the shutdown of the display device and the power amplifier device, the user can promptly perceive that the vehicle is in sleep mode, thereby improving the user's driving experience.

[0058] Optionally, in some embodiments, as shown in FIG4, after receiving the first power-down signal 402, the power supply module 310 can send lower-level unit power-off signals 406 and 407 to the autonomous driving control module 330 and the cockpit domain control module 340 respectively, so as to shut down the lower-level units of the autonomous driving control module 330 and the cockpit domain control module 340 accordingly.

[0059] In some embodiments, if the vehicle interface module 110 does not receive a first working message from the autonomous driving control module within a predetermined time, it may stop supplying power to the autonomous driving module 330 and / or the cockpit domain control module 340.

[0060] As an example, as shown in Figure 4, after receiving the power status signal 408 sent by the vehicle's power conversion module, the vehicle interface module 110 can send sleep signals 409_1, 409-2, and 409-3 to the power supply module 310, the autonomous driving control module 330, and the cockpit domain control module 340. The sleep signals 409_1, 409-2, and 409-3 can, for example, instruct the vehicle interface module 110 to stop sending ignition signals. The power status signal 406 instructs the power conversion module to stop outputting power.

[0061] When the autonomous driving control module 330 and the cockpit domain control module 340 receive sleep signals 409-2 and 409-3 respectively, they enter sleep mode. At this time, the autonomous driving control module 330 and the cockpit domain control module 340 will stop sending working messages 410 and 411 to the vehicle interface module 110.

[0062] After the autonomous driving control module 330 and the cockpit domain control module 340 enter a dormant state, the temperature control module 320 can execute a cooling process 412 to reduce the water temperature of the thermal management system associated with the temperature control module 320.

[0063] Furthermore, when the vehicle interface module 110 does not receive the first working message from the autonomous driving control module for a period of time, the vehicle interface module 110 can send a second power-off signal 413 to the power supply module 310. The power supply module 310 can then execute power-off stops 414 and 415 on the autonomous driving control module 330 and the cockpit domain control module 340, thereby shutting down the autonomous driving control module 330 and the cockpit domain control module 340.

[0064] In some embodiments, the vehicle interface module 110 may stop supplying power to the temperature control module 330 if it does not receive a second working message from the vehicle's temperature control module 330 within a predetermined time period. For example, as shown in FIG4, when the water temperature of the thermal management system drops to a preset temperature, the temperature control module 320 enters a sleep state. At this time, the temperature control module 320 stops sending working messages 416 to the vehicle interface module 110.

[0065] If the vehicle interface module 11O does not receive the second working message within a predetermined time period, it can send a third power-down signal 417 to the power supply module 310. The power supply module 310 can then stop supplying power to the temperature control module 320, thereby shutting down the temperature control module 320. In this way, various vehicle components can be protected during the power-down process, thereby extending the vehicle's service life.

[0066] Optionally, in some embodiments, as shown in FIG4, when the temperature control module 320 is powered off, the vehicle interface module 110 can enter a sleep state. At this time, the vehicle interface module 110 stops sending working messages 419-1 and 419-2 to put other systems and power supply modules of the vehicle into sleep mode.

[0067] In this way, embodiments of the present disclosure enable more efficient and accurate management of the power system.
