[0028] This invention determines the power-on strategy for each functional unit in the autonomous driving control module by powering on each acquisition module and control module of the autonomous driving vehicle, and then executes the power-on operation, thereby realizing the control of each functional unit in the autonomous driving control module to be in different power states at different times based on the needs of the autonomous driving vehicle.

[0029] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the power-on control method for an autonomous driving system in this invention includes:

[0031] 101. Detect whether the autonomous vehicle has an ignition signal;

[0032] The ignition signal can be of the type ANBus ignition signal message, ignition signal level, or power supply voltage, and different types of ignition signals correspond to different ignition signal acquisition methods. After receiving the network data packet according to the preset ignition signal acquisition method, the autonomous vehicle parses the network data packet according to the preset acquisition method, identifies the ignition signal based on the autonomous vehicle's own parameter information and the result of parsing the network data packet, and determines whether the ignition signal meets preset conditions. If it does, it is determined that the autonomous vehicle has an ignition signal.

[0033] 102. If so, generate the first power-on command to power on the data acquisition module and the autonomous driving control module in the autonomous driving system;

[0034] After detecting the ignition signal, a preset first power-on strategy for the autonomous driving system is obtained. This first power-on strategy includes the specific operating parameters of each acquisition module in the autonomous driving system, the specific operating parameters of the autonomous driving module, and the preset power-on timing and power-on completion conditions for each acquisition module and the autonomous driving module. Based on the specific operating parameters and power-on timing, a first power-on command is generated. The first power-on command is used to power on each acquisition module and control module until each acquisition module and control module can work stably. Then, it is determined whether the corresponding power-on completion conditions are met.

[0035] The power-on sequence of each data acquisition module and the autonomous driving module can be determined by random numbers, or it can be customized, etc. The specific method for determining the power-on sequence can be set according to the requirements and is not limited to what is described above.

[0036] 103. Acquire the environmental data around the vehicle currently collected by the acquisition module, as well as the power-on status of the autonomous driving control module;

[0037] The system uses a data acquisition module to obtain the current location, orientation, and obstacle information of the autonomous vehicle. It also acquires the current signal of the autonomous driving control module over a certain period of time. By checking whether the current signal is stable and comparing it with the preset target current signal, the system determines the power-on status of the autonomous driving control module based on the analysis results.

[0038] 104. Determine the operating state of the autonomous driving control module at the next moment based on environmental data and power-on status;

[0039] Based on the current location, orientation, and obstacle information of the autonomous vehicle, determine whether the autonomous vehicle is in an obstacle area and whether the power-on state is complete. If it is in an obstacle area and in a complete state, obtain the current driving speed of the autonomous vehicle and the minimum distance between the autonomous vehicle and the obstacle area. Calculate the predicted driving trajectory of the autonomous vehicle based on the driving speed and the minimum distance, and determine the working state of the autonomous driving control module at the next moment based on the predicted driving trajectory. If it is not in an obstacle area and in a complete state, determine that the autonomous driving control module is in the vehicle start-up state at the next moment.

[0040] Furthermore, if the current signal is stable and its parameters are consistent with the target current signal, then the power-on status of the autonomous driving control module is determined to be complete. The predicted driving trajectory of the autonomous vehicle may be one of the following: going straight, stopping, or turning.

[0041] Furthermore, if the autonomous driving control module is in an incomplete state, the various parameter information of the autonomous driving control module is checked, abnormal parameter information is extracted, abnormal units in the autonomous driving control module are identified based on the abnormal parameter information, and alarm information is generated and output by the abnormal unit and abnormal parameter information.

[0042] 105. Determine the power-on strategy for each functional unit in the automatic driving control module according to the working status, and generate the corresponding power-on command sequence based on the power-on strategy;

[0043] Based on the working state of the autonomous driving control module at the next moment, determine the functional units that match the working state, obtain the position information, power-on time interval and working parameter information of each functional unit, and obtain the position information, power-on time interval and working parameter information of each functional unit contained in each functional unit, generate the power-on strategy of each functional unit in the autonomous driving control module, and generate the corresponding power-on command sequence based on the power-on strategy.

[0044] 106. Power on each functional unit in the autonomous driving control module sequentially based on the power-on command sequence;

[0045] The power-on command sequence is parsed to obtain a random duration corresponding to each of the multiple functional units. When the power-on completion condition of each functional unit is determined to be completed, the multiple functional units are controlled to wait for their respective random durations before powering on.

[0046] 107. After all functional units are powered on, power on the image processing module of the autonomous driving system to process the environmental data.

[0047] The system polls the current power-on status of each functional unit in the control module, checks whether the current signal of the functional unit is stable and whether the current signal reaches the preset current signal threshold. If the current signal is stable and reaches the preset current signal threshold, the system powers on the image processing module in the autonomous driving system and processes the environmental data collected by the acquisition module through the image processing module after power-on.

[0048] Furthermore, the actual control timing of the functional units to be powered on is monitored in real time according to the power-on sequence, and the control timing is compared and analyzed with the power-on sequence; if the comparison is consistent, the power-on result is recorded; if the comparison is inconsistent, the inconsistent functional units are extracted, their error information is recorded and feedback is provided.

[0049] In this embodiment of the invention, after powering on each acquisition module and control module of the autonomous vehicle, the working state of the control module at the next moment is determined, thereby determining the power-on strategy of each functional unit in the control module and executing the power-on operation. This realizes the control of each functional unit in the autonomous driving control module to be in different power states at different times based on the needs of the autonomous vehicle.

[0050] Please see Figure 2 and Figure 3 The second embodiment of the power-on control method for an autonomous driving system in this invention is applied to... Figure 3 The power-on control methods for the autonomous driving system, as shown in the provided overall flowchart, include:

[0051] 201. Detect whether the autonomous vehicle has an ignition signal;

[0052] The system determines whether to detect IGN (ignition signal) based on DC-IN (direct current input line). If IGN is detected to be high, all functional modules of the autonomous vehicle's MCU (microcontroller unit), PMIC (power management chip), and CPLD (complex programmable logic device) are activated.

[0053] 202. If so, generate the first power-on command to power on the data acquisition module and the autonomous driving control module in the autonomous driving system;

[0054] The first power-on command is generated and parsed to obtain the functional units that are powered on based on the first power-on command. These functional units include: vehicle CAN module, network switch module, camera module and autonomous driving control module.

[0055] 203. Obtain the environmental data around the vehicle currently collected by the acquisition module, as well as the power-on status of the autonomous driving control module;

[0056] The vehicle uses an onboard CAN module, network switch module, and camera module to collect environmental data about the vehicle's current surroundings, determine the current location of the autonomous vehicle and information about surrounding obstacles, and detect whether the power-on status of the autonomous driving control module is "CPLD power ok" (control module has been powered on).

[0057] 204. Determine the operating state of the autonomous driving control module at the next moment based on environmental data and power-on status;

[0058] If the CPLD is in the "power ok" state, based on the current location information of the autonomous vehicle and the information of surrounding obstacles, the possible operating direction of the autonomous vehicle in the next moment is predicted. The operating direction may be at least one of the following: parking in the behavior area, driving along the road, or turning at the intersection.

[0059] 205. Determine the power-on strategy for each functional unit in the automatic driving control module according to the working status, and generate the corresponding power-on command sequence based on the power-on strategy;

[0060] Based on the working status, the system matches the functional unit to be powered on from the preset correspondence table between working status and functional unit; generates the corresponding power-on strategy based on the working parameters and timing of the functional unit to be powered on; and generates the corresponding power-on instruction sequence based on the power-on strategy.

[0061] Furthermore, the position information of each circuit unit in the functional unit to be powered on and the preset power-on time interval are obtained; the corresponding power-on strategy is generated using the position information and the power-on time interval.

[0062] 206. Analyze the time points of valid signals in the power-on command sequence, and adjust the power supply timing of the autonomous driving system based on each time point to obtain the power-on timing of the functional units to be powered on.

[0063] The power-on command sequence is parsed to obtain the effective signal time points of each functional unit in the control module. Based on these effective signal time points, the rationality of the generated power-on strategy is checked. If it is not rational, the power supply timing in the autonomous driving system is adjusted based on each time point to obtain the power-on timing of the functional unit to be powered on. If it is rational, the power-on timing in the power-on strategy is output as the power-on timing of the functional unit to be powered on.

[0064] 207. Based on the power-on sequence, the functional units to be powered on are powered on sequentially;

[0065] The power-on sequence is converted into the effective level value of the corresponding functional unit by several transformer components, resulting in a binary string; the power supply pin of the functional unit to be powered on is controlled based on the binary string to realize the power-on operation.

[0066] For example, an autonomous driving control module contains three functional units. The power-on sequence is determined to be functional unit 1, functional unit 2, and functional unit 3. The power-on sequence of the three functional units is as follows: control functional unit 1 is powered on at the time point of the valid signal. When the power-on completion condition of functional unit 1 is met, control functional unit 2 is powered on at the time point of the valid signal. When the power-on completion condition of functional unit 2 is met, control functional unit 3 is powered on at the time point of the valid signal. When the power-on completion condition of functional unit 3 is met, the power-on process of the autonomous driving control module ends.

[0067] 208. After all functional units are powered on, power on the image processing module of the autonomous driving system to process the environmental data.

[0068] The CPLD detect PWR-EN (CPLD detector pin) polls the current power-on status information of each functional unit. After issuing the power-on completion command, the control module of the autonomous vehicle sends a POWER ON (power-on complete) signal to the autonomous vehicle, turns on the GPU (graphics processing module) power based on the MCU, and boots to the OS (preparing the boot files for the autonomous vehicle system).

[0069] In this embodiment of the invention, after powering on each acquisition module and control module of the autonomous vehicle, the working state of the control module at the next moment is determined, thereby identifying the functional units in the control module that need to be powered on. A power-on command sequence is generated for each functional unit to be powered on. After parsing the power-on command sequence to obtain the time point of the valid signal, the power-on timing sequence of the functional units to be powered on is generated. The power-on operation is performed according to the power-on timing sequence, thereby realizing the sequential power-on of each functional unit in the autonomous driving control module and enhancing the reliability of power supply to the autonomous driving system.
