Description

Technical Field

[0001] This invention relates to the field of autonomous driving assistance systems, and in particular to an autonomous driving system control method, apparatus, device, and storage medium. Background Technology

[0002] As the electronic and electrical architecture of vehicles evolves, controllers are becoming increasingly integrated. Distributed architectures are costly and have limited system functionality, making them unable to meet current demands. Advanced autonomous driving requires numerous sensor inputs and high computing power, which traditional distributed systems cannot satisfy. The current mainstream solution is based on autonomous driving domain controllers and associated autonomous driving sensors. However, the drawback of high-computing-power domain controllers and multiple sensors is their high power consumption, which remains significant even when the autonomous driving function is not in operation.

[0003] Advanced autonomous driving systems often employ redundant designs, with controllers composed of multiple chips. When the autonomous driving function is not activated, the power consumption of these multiple chips is relatively high. Similarly, not all sensors need to be constantly operational; they do not need to be in an active state when the function is not activated. Therefore, under these circumstances, it is necessary to manage the power supply of the controller and sensors to reduce vehicle power consumption. Summary of the Invention

[0051] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0052] Please see Figure 1 As shown, Figure 1 This embodiment of the present application illustrates a block diagram of a high-level autonomous driving system architecture. The architecture includes an autonomous driving domain controller 11 and sensors 12. The autonomous driving domain controller 11 controls the operation of the sensors 12. The autonomous driving domain controller 11 internally includes a main control module 111 and a redundant control module 112, which intervenes when the main control module 111 fails. The main control module 111 includes a system-on-a-chip (SoC) 1 and a microcontroller chip (MCU) 1, and the redundant control module 112 includes a redundant SoC 2 and a redundant MCU 2.

[0053] The aforementioned advanced autonomous driving system employs a redundant design to ensure the safe operation of the autonomous vehicle even if the main control module 111 fails. However, when the autonomous driving function is not activated, the power consumption will be significant if numerous chips within the autonomous driving domain controller are active. Furthermore, maintaining the operation of all sensors while the autonomous driving function is inactive will also result in substantial power consumption. Therefore, power management for the autonomous driving domain controller and sensors is necessary to reduce vehicle power consumption under these conditions.

[0054] To address these issues, embodiments of this application propose an autonomous driving system control method, device, and storage medium, which will be described in detail below.

[0055] First, it's important to note that if the autonomous driving system isn't set to enter low-power mode, it operates at full power. In this mode, the autonomous vehicle operates with all functions enabled (including autonomous driving comfort functions, automatic emergency braking, lane departure warning, and a dashcam). This means that within the autonomous driving system's domain controller, only the main system-on-a-chip (SOC1), main microcontroller (MCU1), redundant main system-on-a-chip (SOC2), and redundant microcontroller (MCU2) are active. The side-view cameras, rear-view cameras, and LiDAR among the safety assistance sensors are in sleep mode, while the front-view camera, surround-view cameras, forward-facing millimeter-wave radar, and side-facing millimeter-wave radar are active. Power consumption in this mode is extremely high.

[0056] Please see Figure 2 As shown, Figure 2 This is a flowchart illustrating a control method for an autonomous driving system, as shown in an exemplary embodiment of this application. (In conjunction with...) Figure 2 As shown, an embodiment of the present disclosure provides a control method for an autonomous driving system, comprising:

[0057] Step S210: Perform fault checks on the vehicle human-machine interaction module, autonomous driving domain controller, and safety assistance sensors;

[0058] Step S220: When the vehicle human-machine interaction module, the autonomous driving domain controller and the safety assistance sensors are all fault-free, the low-power mode of the autonomous driving system is activated.

[0059] Step S230: Receive a low-power input command from the user through the vehicle's human-machine interaction module;

[0060] Step S240: Parse the low-power input command to obtain the low-power power level;

[0061] Step S250: Based on the low power consumption level, control some chips of the autonomous driving domain controller to be in a sleep state according to preset rules, and control some or all of the safety auxiliary sensors to be in a sleep state.

[0062] The control method for an autonomous driving system provided in this disclosure first performs fault checks on the vehicle's human-machine interface module, autonomous driving domain controller, and safety assistance sensors after the vehicle is powered on. When the autonomous driving domain controller and sensors are all fault-free, the low-power mode of the autonomous driving system is activated. It receives low-power input commands from the user through the vehicle's human-machine interface module, parses these commands to obtain the low-power power level, and finally, based on the low-power power level, controls some chips in the autonomous driving domain controller to enter a sleep state according to preset rules, and controls some or all of the safety assistance sensors to enter a sleep state. The control method for an autonomous driving system provided in this disclosure allows the system to enter a low-power mode through user settings when the autonomous driving system is not activated. After the user settings are completed, the software manages the power supply of the autonomous driving assistance sensors and the autonomous driving domain controller, greatly reducing the system power consumption when the autonomous driving system is not activated.

[0063] Now combined with the appendix Figure 2 and attached Figure 3 Let's take a detailed look at the implementation process of each step:

[0064] First, step S210 is executed to perform fault checks on the vehicle human-machine interaction module, the autonomous driving domain controller, and the safety assistance sensors.

[0065] First, it should be noted that the autonomous driving control system described in this invention includes a human-machine interface (HMI) module, an autonomous driving domain controller, and safety assistance sensors. The safety assistance sensors include forward-facing millimeter-wave radar, side-facing millimeter-wave radar, lidar, a forward-looking camera, a side-facing camera, a surround-view camera, and a surround-view camera. The system includes a forward-facing camera for sensing lane lines and targets, controlled by a domain controller for power supply and exposure; a forward-facing millimeter-wave radar for sensing targets, controlled by energy consumption levels for sleep / wake-up; a side-facing millimeter-wave radar for sensing targets, controlled by energy consumption levels for sleep / wake-up; a side-facing camera for detecting vehicles and lane lines on the sides by recognizing objects in the forward and rearward directions, controlled by the autonomous driving domain controller for power supply; a surround-view camera primarily used for parking, but can also function as a dashcam, controlled by the autonomous driving domain controller for power supply and shutdown; a rear-view camera primarily used for capturing images behind the vehicle during reversing, enabling parking assistance, controlled by the autonomous driving domain controller for power supply and shutdown; and a lidar system for sensing static objects, pedestrians, vehicles, and obstacles in the forward and lateral directions, controlled by the autonomous driving domain controller for power supply and shutdown.

[0066] Please see Figure 3As shown, in one embodiment, fault checks are performed on the vehicle human-machine interaction module, the autonomous driving domain controller, and the safety assistance sensors, specifically including:

[0067] Step S310: The vehicle human-machine interaction module is initialized and a fault is detected.

[0068] Step S320: The autonomous driving domain controller performs a self-test and feeds back the results to the vehicle human-machine interaction module.

[0069] In step S330, the safety auxiliary sensor performs a self-test and feeds back the result to the vehicle's human-machine interaction module.

[0070] First, after the vehicle is powered on, the vehicle's human-machine interface (HMI) module initializes and checks for faults. If no faults are detected, the HMI module defaults to full-function mode. Next, the autonomous driving domain controller performs a self-test after power-on. If a fault is detected, the result is fed back to the HMI module. At this time, the low-power mode of the autonomous driving system on the HMI module interface is disabled, meaning users are not allowed to manually enter low-power mode. Even if no faults are detected, feedback still needs to be sent to the HMI module. Finally, the safety assistance sensors perform a self-test after power-on. If a fault is detected, the result is fed back to the HMI module. At this time, the low-power mode of the autonomous driving system on the HMI module interface is disabled, meaning users are not allowed to manually enter low-power mode. Even if no faults are detected, feedback still needs to be sent to the HMI module.

[0071] Next, step S220 is executed. When the autonomous driving control system, autonomous driving domain controller and sensors are all fault-free, the low power mode of the autonomous driving system is activated.

[0072] It should be noted that the low-power mode of the autonomous driving system described in this embodiment is in an active state, which means that the low-power mode control switch of the autonomous driving system on the vehicle human-machine interaction module interface is in a normal working state. That is, the user can make the chip in the autonomous driving domain controller perform corresponding operations by clicking the low-power mode control switch.

[0073] It should also be noted that during vehicle operation, when the vehicle's human-machine interaction module detects that the autonomous driving function is activated, the low-power mode of the autonomous driving system exits the activation state.

[0074] Next, step S230 is executed to receive a low-power input command from the user through the vehicle human-machine interaction module;

[0075] The autonomous driving domain controller receives low-power commands sent by the user through the vehicle's human-machine interface (HMI) module, and performs corresponding operations according to the requirements of the commands.

[0076] Next, step S240 is executed to parse the low-power input command in order to obtain the low-power power level;

[0077] Because the low-power input commands sent by users contain a lot of information, such as the address information of the sender and receiver, and the low-power power level information, the autonomous driving domain controller needs to parse the low-power input commands to obtain the low-power power level information.

[0078] Finally, step S250 is executed, in which, according to the low power level, some chips of the autonomous driving domain controller are controlled to be in a sleep state according to preset rules, and some or all of the safety auxiliary sensors are controlled to be in a sleep state.

[0079] First, it should be noted that the microcontroller chip in the autonomous driving domain controller can control the sleep and closure of safety assistance sensors.

[0080] It should also be noted that in this embodiment, the low power supply level includes a normal power saving mode and a super power saving mode. When the low power supply level is in the normal power saving mode, the autonomous driving system only retains the safety assistance functions (specifically including automatic emergency braking, refrigerator assistance, and driving recorder). That is, only the main system-on-a-chip SOC1 and the main microcontroller MCU1 are active in the autonomous driving system domain controller. The side-view camera, rear-view camera, and lidar in the safety assistance sensors are in a dormant state, while the front-view camera, surround-view camera, forward millimeter radar wave, and side millimeter radar wave in the safety assistance sensors are active. When the low-power power level is in ultra-low power saving mode, the comfort function and safety assistance function of the autonomous driving system are both turned off. That is, only the main microcontroller MCU1 in the autonomous driving system domain controller is active to support normal message transmission and reception. The main system-on-a-chip SOC1, the redundant system-on-a-chip SOC2, and the redundant microcontroller in the autonomous driving system domain controller are in sleep mode. The side-view camera, rear-view camera, and LiDAR in the safety assistance sensors are in sleep mode, while the front-view camera, surround-view camera, forward millimeter radar, and side millimeter radar in the safety assistance sensors are active.

[0081] In one embodiment of the present invention, in order to ensure safety during autonomous driving, the method further includes:

[0082] During vehicle operation, the vehicle human-machine interaction module monitors the status of the autonomous driving function;

[0083] If the autonomous driving function is detected to be active, then the low-power mode of the autonomous driving system is disabled.

[0084] Figure 4 This diagram illustrates a block diagram of an autonomous driving system control device 400 according to an exemplary embodiment of this application. The autonomous driving system control device 400 includes a fault detection module 401, a mode activation module 402, a signal acquisition module 403, a parsing module 404, and an execution module 405. The fault detection module 401 is used to perform fault checks on the vehicle human-machine interface module, the autonomous driving domain controller, and the safety assistance sensors after the vehicle is powered on. The low-power activation module 402 is used to activate the low-power mode of the autonomous driving system when the autonomous driving control system, the autonomous driving domain controller, and the sensors are all fault-free.

[0085] The signal acquisition module 403 is used to receive low-power input commands input by the user through the vehicle human-machine interaction module; the parsing module 404 is used to parse the low-power input commands to obtain the low-power power level; the execution module 405 is used to control some chips of the autonomous driving domain controller to be in a sleep state according to the low-power power level and according to preset rules, and to control some or all of the safety assistance sensors to be in a sleep state.
