Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, specifically to a pre-start control method, device, and equipment for an intelligent driving controller. Background Technology

[0002] The success or failure of intelligent vehicles hinges on autonomous driving, and the level of autonomous driving depends on the computing platform that acts as the brain of the intelligent vehicle. Therefore, the MDC (Intelligent Driving Controller) plays a crucial role in intelligent driving scenarios. Typically, an MDC has a dense computing power of 400+ TOPS, 16 cameras, and interacts with 12 CAN (Controller Area Network) connections and 8 in-vehicle Ethernet connections. Consequently, the MDC's CPU generates significant heat during high-power data analysis and processing. Furthermore, the MDC requires the entire vehicle to be under high pressure to start operating.

[0003] Traditional methods for applying high-voltage power to a vehicle involve the user unlocking the door with a smart key. Once the door is unlocked, the BCM (Body Control Controller) activates the IGN relay (IGN is a low-voltage relay controlled by the BCM), triggering the VCU (Vehicle Control Unit) to apply high-voltage power. After this activation, the MDC (Motorcycle Control Unit) then starts up and is cooled. However, the inventors of this application discovered through applied research that, when a user requests high-voltage power, this existing method cannot quickly bring the MDC into working mode and is time-consuming, increasing the user's waiting time and reducing the driving experience. Summary of the Invention

[0004] To address the technical problem that existing intelligent vehicle high-voltage power-on methods cannot quickly put the MDC into working mode and take a long time, increasing user waiting time and reducing user driving experience, this invention provides a liquid-cooled pre-start control method, device, equipment, and storage medium for intelligent driving controllers.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] On one hand, the present invention provides a liquid-cooled pre-start control method for an intelligent driving controller, comprising:

[0007] The system determines whether the user intends to use the vehicle. If so, the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller.

[0008] After the vehicle controller performs high-voltage power-on of the vehicle, the vehicle controller starts the thermal management system to control the water pump and uses the first heating method to liquid cool the intelligent driving controller.

[0009] After receiving the high-voltage request sent by the intelligent driving controller, the vehicle controller detects whether there is a high-voltage power-on trigger source. If not, the vehicle controller executes the vehicle high-voltage power-off.

[0010] The temperature of the intelligent driving controller is obtained, and the temperature of the intelligent driving controller is compared with a preset temperature threshold to obtain the comparison result;

[0011] Based on the comparison results, the vehicle controller activates the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller.

[0012] Furthermore, based on the comparison results, the vehicle controller activating the thermal management system to control the water pump and employing a second heating method to liquid cool the intelligent driving controller includes:

[0013] If the temperature of the intelligent driving controller is greater than or equal to the preset temperature threshold, the intelligent driving controller sends a liquid-cooled low-pressure operation request to the vehicle controller. After receiving the liquid-cooled low-pressure operation request, the vehicle controller starts the thermal management system to control the water pump and uses a second heating method to liquid-cool the intelligent driving controller.

[0014] The temperature of the intelligent driving controller after liquid cooling is obtained within a preset time, and the temperature after liquid cooling is compared with the preset temperature threshold.

[0015] If the temperature after liquid cooling is lower than the preset temperature threshold, the thermal management system stops controlling the water pump to liquid cool the intelligent driving controller and controls the vehicle controller to go into sleep mode.

[0016] Furthermore, the step of determining whether the user intends to use the vehicle, and if so, the intelligent driving controller sending a high-voltage power-on request signal to the vehicle controller includes:

[0017] If no key unlocking request is received, and the intelligent driving controller receives a Bluetooth key signal carrying the target location, then the first triggering condition is met, wherein the target location includes the welcoming area and the unlocking area;

[0018] When a key unlocking request is received, if the intelligent driving controller receives an unlocking request signal from the Bluetooth key, then the second triggering condition is met.

[0019] If the intelligent driving controller receives a CANFD signal and the driver's door lock status changes from closed to open, then the third triggering condition is met;

[0020] If at least one of the first triggering condition, the second triggering condition, and the third triggering condition is met, it is determined that the user intends to use the vehicle, and the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller.

[0021] Furthermore, after the Bluetooth Low Energy controller is woken up by detecting the key signal, it wakes up the gateway controller through a network management message; after the gateway controller is woken up, it simultaneously wakes up the body controller, intelligent driving controller and vehicle controller through a network management message, so that the controller is in an initialization standby state.

[0022] Furthermore, if the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller for more than a first preset time, and the vehicle controller detects that the power mode of the body controller is IGN OFF, the vehicle controller will control the vehicle to shut down the high voltage.

[0023] Furthermore, the vehicle controller activates the thermal management system to control the water pump and uses a first heating method to liquid cool the intelligent driving controller, including:

[0024] The vehicle controller sends an enable signal and a voltage setting signal to the DC-DC converter, enabling the DC-DC converter to operate and allowing the high-voltage electricity from the battery management system to be converted into low-voltage electricity by the DC-DC converter, providing working power to the water pump and the vehicle controller.

[0025] Furthermore, after the vehicle controller activates the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller, it also includes:

[0026] When the vehicle controller detects that the liquid cooling low pressure operation request sent by the intelligent driving controller is not received, or when the liquid cooling duration of the intelligent driving controller exceeds the second preset duration, the vehicle controller will start hibernation after the hibernation conditions are met.

[0027] On the other hand, the present invention provides a liquid-cooled pre-start control device for an intelligent driving controller, comprising:

[0028] The pre-start entry control module is used to determine whether the user intends to use the vehicle. If so, the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller. After the vehicle controller performs the high-voltage power-on, the vehicle controller starts the thermal management system to control the water pump and uses the first heating method to liquid cool the intelligent driving controller.

[0029] The pre-start-up exit control module is used to detect whether there is a high-voltage power-on trigger source after the vehicle controller receives a high-voltage request sent by the intelligent driving controller. If not, the vehicle controller will execute the vehicle high-voltage power-off.

[0030] The pre-start operation control module is used to obtain the temperature of the intelligent driving controller and compare the temperature of the intelligent driving controller with a preset temperature threshold to obtain a comparison result; based on the comparison result, the vehicle controller starts the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller.

[0031] In another aspect, the present invention provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps in the liquid-cooled pre-start control method of the intelligent driving controller described above.

[0032] In another aspect, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps in the liquid-cooled pre-start control method of the intelligent driving controller described above.

[0033] Compared with the prior art, the liquid-cooled pre-start control method, device, equipment and storage medium of the intelligent driving controller provided by the present invention determines whether the user intends to use the vehicle. If so, the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller. After the vehicle controller performs high-voltage power-on, it starts the thermal management system to control the water pump and uses a first heating method to liquid cool the intelligent driving controller. After receiving the high-voltage request from the intelligent driving controller, the vehicle controller detects whether there is a high-voltage power-on trigger source. If not, the vehicle controller performs high-voltage power-off. It obtains the temperature of the intelligent driving controller and compares it with a preset temperature threshold to obtain a comparison result. Based on the comparison result, the vehicle controller starts the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller. This application is mainly used in the rapid start-up and remote parking scenarios of the cold start AVM (panoramic monitoring image system) of the intelligent driving controller. By judging whether the user intends to use the vehicle, if so, the pre-start completes the high voltage power supply of the whole vehicle in advance, so that the intelligent driving controller can quickly enter the standby working state, which greatly shortens the user's waiting time or even eliminates the waiting time, allowing the user to use the car's intelligent driving system at will. For example, the user can enjoy the intelligent driving function as soon as they get in the car, thereby improving the user's driving experience. Attached Figure Description

[0035] Figure 2 This is a detailed flowchart of the liquid-cooled pre-start control method for an intelligent driving controller provided in an embodiment of the present invention.

[0036] Figure 3 This is a structural block diagram of the liquid-cooled pre-start control device for the intelligent driving controller provided in an embodiment of the present invention. Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0038] As one specific embodiment, please refer to Figure 1 and Figure 2 As shown, the present invention provides a liquid-cooled pre-start control method for an intelligent driving controller, comprising:

[0039] The system determines whether the user intends to use the vehicle. If so, the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller.

[0040] After the vehicle controller performs high-voltage power-on of the vehicle, the vehicle controller starts the thermal management system to control the water pump and uses the first heating method to liquid cool the intelligent driving controller (because the CPU of the intelligent driving controller is in a high computing power state when it is working, resulting in a large amount of heat generation, so liquid cooling of the MDC hardware controller is required).

[0041] After receiving the high-voltage request sent by the intelligent driving controller, the vehicle controller detects whether there is a high-voltage power-on trigger source. If not, the vehicle controller executes the vehicle high-voltage power-off.

[0042] The temperature of the intelligent driving controller is obtained, and the temperature of the intelligent driving controller is compared with a preset temperature threshold to obtain the comparison result;

[0043] Based on the comparison results, the vehicle controller activates the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller, thereby reducing the temperature of the intelligent driving controller hardware.

[0044] In one embodiment, based on the comparison result, the vehicle controller activates the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller, including:

[0045] If the temperature of the intelligent driving controller is greater than or equal to the preset temperature threshold, the intelligent driving controller sends a liquid-cooled low-pressure operation request to the vehicle controller. After receiving the liquid-cooled low-pressure operation request, the vehicle controller starts the thermal management system to control the water pump and uses a second heating method to liquid-cool the intelligent driving controller.

[0046] The process of obtaining the temperature of the intelligent driving controller after liquid cooling within a preset time and comparing the temperature after liquid cooling with the preset temperature threshold specifically includes: after receiving the high voltage power-down state of the vehicle, the intelligent driving controller detects its own hardware temperature through its own sensors and determines whether its own hardware temperature is suitable, that is, comparing its own hardware temperature after liquid cooling with the preset temperature threshold.

[0047] If the temperature after liquid cooling is lower than the preset temperature threshold, the thermal management system stops controlling the water pump to liquid cool the intelligent driving controller and controls the vehicle controller to go into sleep mode. Specifically, when the temperature of the liquid-cooled hardware is lower than the preset temperature threshold, i.e., when the temperature is suitable, the intelligent driving controller sends a "No Request" request for liquid cooling after low pressure operation. When the temperature of the liquid-cooled hardware is greater than or equal to the preset temperature threshold, i.e., when the temperature is overheated, the intelligent driving controller sends a "Request" request for liquid cooling after low pressure operation to notify the vehicle controller to start the thermal management system to control the water pump to liquid cool the intelligent driving controller hardware. Under normal circumstances, the liquid cooling requirement of the intelligent driving controller hardware is 1-2 minutes. After the SOC (System-on-a-Chip) in the intelligent driving controller completes its power-down sleep mode, it comprehensively judges that it meets the sleep conditions and then controls the vehicle controller to perform the sleep action.

[0048] Specifically, in this embodiment, the second heating method involves using a low-voltage battery to provide operating power to the water pump and the vehicle controller, and controlling the water pump through the thermal management system to perform liquid cooling on the intelligent driving controller. The reason for using the second heating method to liquid cool the intelligent driving controller in this embodiment is that after the high-voltage power is cut off, the battery pack of the battery management system no longer outputs high voltage; therefore, only a low-voltage battery can be used to provide operating power to the water pump and the vehicle controller for liquid cooling.

[0049] In one implementation, determining whether the user intends to use the vehicle, and if so, the intelligent driving controller sending a high-voltage power-on request signal to the vehicle controller includes:

[0050] If no key unlocking request is received, and the intelligent driving controller receives a Bluetooth key signal carrying the target location, then the first triggering condition is met. The target location includes the welcome area and the unlocking area. For example, the intelligent driving controller receives a Bluetooth key signal sent by the Bluetooth Low Energy (BLE) controller forwarded by the body controller, which carries the location information of the Bluetooth key. At this time, the driver's door is closed.

[0051] When a key unlocking request is received, if the intelligent driving controller receives an unlocking request signal from a Bluetooth key, then the second triggering condition is met; for example, the intelligent driving controller receives a Bluetooth key unlocking request signal sent by a Bluetooth Low Energy controller forwarded by the body controller.

[0052] If the intelligent driving controller receives a CANFD (CAN with Flexible Data rate) signal and the driver's door lock status changes from closed to open, then the third triggering condition is met; for example, the intelligent driving controller receives a CANFD signal sent by the body controller and the driver's door lock status changes from closed to open.

[0053] If at least one of the first triggering condition, the second triggering condition, and the third triggering condition is met, it is determined that the user intends to use the vehicle, and the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller.

[0054] Specifically, in this embodiment, the triggering conditions are mainly based on user scenarios, and the key signal and door status detection cover all possibilities when the user intends to use the vehicle.

[0055] In one implementation, the Bluetooth Low Energy controller sends the signal indicating the location of the Bluetooth key (welcome area or unlock area) and the Bluetooth key unlock request signal, which are specifically detected by the radio frequency antenna of the Bluetooth Low Energy controller and then sent to the vehicle body controller. At this time, the Bluetooth Low Energy controller is woken up.

[0056] In one implementation, after the Bluetooth Low Energy controller is woken up by detecting the key signal, it wakes up the gateway controller (GW) via a network management (NM) message; after the gateway controller is woken up, it synchronously wakes up the body controller, intelligent driving controller and vehicle controller via a network management message, so that each controller is in an initialization standby state.

[0057] In one implementation, the vehicle body controller (BCM) forwards key signals sent by the BLE, including signals indicating the key's location and key unlocking request signals. Upon receiving the key unlocking request signal from the BLE, it performs unlocking actions on all four vehicle doors and reports the door lock status to the MDC via CANFD messages. It also detects the driver's door status via hardwired communication, processes the logic, and reports the door status signal to the MDC. Under normal circumstances, after the vehicle wakes up from sleep mode, the BCM detects a change in the driver's door status (from closed to open), initiates low-voltage power-on for the entire vehicle, controls the KL15 relay to close, and reports the BCM power status signal to the vehicle. The vehicle controller can trigger high-voltage power-on conditions by detecting the KL15 relay or the BCM power mode being IGN ON.

[0058] In one implementation, the intelligent driving controller is used to start timing and wake up the SOC and Lidar (Light Detection and Ranging) / INS (Inertial Navigation System) sensors after comprehensively detecting that the above-mentioned triggering conditions are met, and continuously send a high-voltage power-on request signal (ADS_HVCtrlReq = Request) to the vehicle controller.

[0059] In one embodiment, when the vehicle controller receives a high-voltage power-on request signal (ADS_HVCtrlReq = Request) sent by the intelligent driving controller, it performs a high-voltage power-on action based on the vehicle status, and reports the high-voltage power status to the intelligent driving controller after the power-on is completed.

[0060] In one embodiment, if the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller for more than a first preset time, and the vehicle controller detects that the body controller power mode is low-voltage relay off (IGNOFF), the vehicle controller will control the vehicle to shut down the high-voltage power supply if there are no other high-voltage power-on requirements based on the vehicle status. These high-voltage power-on / off requirements include, but are not limited to: IGN ON high-voltage power-on request / fast / slow charging high-voltage power-on request / V2V (Vehicle to Vehicle) and V2L (Vehicle to Load) discharge high-voltage power-on request / remote battery heating high-voltage power-on request, etc. In this embodiment, the first preset time can be set to 5 minutes based on experience. The 5-minute time setting is mainly to allow the user time to consider. If the user does not operate or perform any vehicle-getting actions within 5 minutes, the system assumes that the user has no vehicle-getting needs, and to avoid energy consumption of the battery management system (BMS), it will perform a high-voltage power-off action.

[0061] In one embodiment, the vehicle controller activates the thermal management system to control the water pump and uses a first heating method to liquid cool the intelligent driving controller, including:

[0062] The vehicle controller sends an enable signal and a voltage setting signal to the DC-DC converter to enable the DC-DC converter to work. The high voltage of the battery management system is converted into low voltage by the DC-DC converter to provide working power to the water pump and the vehicle controller. The DC-DC converter continuously reports its own working status, and at the same time, the vehicle controller also continuously reports the liquid cooling status to the intelligent driving controller.

[0063] Specifically, in this embodiment, the first heating method involves converting the high-voltage electricity from the battery management system into low-voltage electricity via a DC-DC converter to provide operating power to the water pump and vehicle controller. The water pump is then controlled by the thermal management system to perform liquid cooling on the intelligent driving controller. The reason for using the first heating method for liquid cooling of the intelligent driving controller in this embodiment is that the battery pack of the battery management system can output high voltage after high-voltage power is applied. Therefore, the high voltage output by the battery management system can be converted into low-voltage electricity via a DC-DC converter to provide operating power to the water pump and vehicle controller for liquid cooling.

[0064] In one implementation, the intelligent driving controller will send a high-voltage power-down request signal to the vehicle controller, and the vehicle controller will execute a vehicle high-voltage power-down, provided that any of the following conditions are met:

[0065] When the intelligent driving controller reaches the first duration, the intelligent driving controller receives the BCM power mode ≠ IGN ON, the MCU in the intelligent driving controller requests SOC sleep mode, and the intelligent driving controller sends a high voltage power-down request signal (ADS_HVCtrlReq = No Request) to the vehicle controller; wherein, the first duration can be set according to actual experience, for example, it can be set to 2.5min, 3min, etc.;

[0066] When the intelligent driving controller starts timing for the second duration, it receives a liquid cooling status (OFF / Failure) signal from the vehicle controller or a DC-DC converter abnormal status signal (≠ operating status) from the DC-DC converter. The MCU in the intelligent driving controller then requests SOC sleep mode, and the intelligent driving controller sends a high-voltage power-down request signal (ADS_HVCtrlReq = No Request) to the vehicle controller. The second duration can be set based on practical experience, for example, 30 seconds, 35 seconds, etc.

[0067] If the signal is lost and the BCM power status signal or the liquid cooling signal or high voltage power status signal of the vehicle controller is not received for several consecutive cycles (which can be set according to actual experience, such as 10 cycles, 11 cycles, etc.), the MCU in the intelligent driving controller requests the SOC to go to sleep, and the intelligent driving controller sends a high voltage power-down request signal (ADS_HVCtrlReq = No Request) to the vehicle controller.

[0068] After the SOC in the intelligent driving controller goes into sleep mode and is powered down, the intelligent driving controller sends a high-voltage power-down request signal (ADS_HVCtrlReq = No Request) to the vehicle controller.

[0069] The intelligent driving controller detects a transition in the BCM power mode from IGN OFF to IGN ON, and sends a high-voltage power-down request signal (ADS_HVCtrlReq = No Request) to the vehicle controller.

[0070] To prevent the ping-pong effect (where a user repeatedly fails to get into the vehicle even when within the vehicle's key detection range), which would cause the vehicle to repeatedly perform high-voltage power-on and power-off cycles, the intelligent driving controller will stop performing the pre-start function if it triggers pre-start multiple times (which can be set based on actual experience, such as 3 or 4 times) without detecting the vehicle being IGNON. The count will be cleared only after IGNON is detected.

[0071] In one embodiment, the vehicle controller performing the vehicle high-voltage power-off includes: controlling the main positive and main negative relays of the battery management system to disconnect, performing vehicle high-voltage discharge, stopping the DC-DC converter from being enabled, and reporting the vehicle high-voltage status to the intelligent driving controller.

[0072] In one embodiment, after the vehicle controller activates the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller, it further includes:

[0073] When the vehicle controller detects that the liquid-cooled low-pressure operation request sent by the intelligent driving controller is not received, or when the liquid cooling duration of the intelligent driving controller exceeds a second preset duration, the vehicle controller initiates hibernation after meeting the hibernation conditions. The second preset duration can be set based on practical experience, for example, it can be set to 1 minute, 1.5 minutes, 2 minutes, etc. The reason for setting the second preset duration for timeout judgment is that the power supply for the water pump and the power supply for the vehicle controller after liquid cooling low pressure operation are both provided by the low-voltage battery, thus ensuring that the low-voltage battery is not excessively depleted.

[0074] Therefore, those skilled in the art should understand that although the steps in the flowchart are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows, unless explicitly stated herein, i.e., there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least some steps in the flowchart may include multiple sub-steps or multiple stages. These sub-steps or stages do not necessarily need to be completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages does not necessarily have to be sequential, but can be executed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.

[0075] As another specific embodiment, please refer to Figure 3 As shown, the present invention provides a liquid-cooled pre-start control device for an intelligent driving controller, comprising:

[0076] The pre-start entry control module is used to determine whether the user intends to use the vehicle. If so, the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller. After the vehicle controller performs the high-voltage power-on, the vehicle controller starts the thermal management system to control the water pump and uses the first heating method to liquid cool the intelligent driving controller.

[0077] The pre-start-up exit control module is used to detect whether there is a high-voltage power-on trigger source after the vehicle controller receives a high-voltage request sent by the intelligent driving controller. If not, the vehicle controller will execute the vehicle high-voltage power-off.

[0078] The pre-start operation control module is used to obtain the temperature of the intelligent driving controller and compare the temperature of the intelligent driving controller with a preset temperature threshold to obtain a comparison result; based on the comparison result, the vehicle controller starts the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller.

[0080] Therefore, those skilled in the art should understand that each functional module in the control device of the above-mentioned intelligent driving controller for new energy vehicles can be implemented in whole or in part through software, hardware, or a combination thereof. Moreover, each of the above-mentioned functional modules can be embedded in the processor of the computer device in hardware form or independent of the processor, or stored in the memory of the computer device in software form, so that the processor can call and execute the corresponding operations of each of the above modules.

[0081] In one embodiment, a computer device is provided, which may be a terminal, the internal structure of which is known to those skilled in the art. The computer device includes a processor, memory, network interface, display, and input device connected via a system bus. The processor provides computing and control capabilities.

The network interface is used to communicate with an external terminal via a network connection. When the computer program is executed by the processor, it implements a liquid-cooled pre-start control method for a new energy vehicle intelligent driving controller. The display of the computer device may be a liquid crystal display or an electronic ink display. The input device may be a touch layer covering the display, buttons or a touchpad on the computer device casing, or an external keyboard, touchpad, or mouse.

[0083] The system determines whether the user intends to use the vehicle. If so, the intelligent driving controller sends a high-voltage power-on request signal to the vehicle controller.

[0084] After the vehicle controller performs high-voltage power-on of the vehicle, the vehicle controller starts the thermal management system to control the water pump and uses the first heating method to liquid cool the intelligent driving controller.

[0085] After receiving the high-voltage request sent by the intelligent driving controller, the vehicle controller detects whether there is a high-voltage power-on trigger source. If not, the vehicle controller executes the vehicle high-voltage power-off.

[0086] The temperature of the intelligent driving controller is obtained, and the temperature of the intelligent driving controller is compared with a preset temperature threshold to obtain the comparison result;

[0087] Based on the comparison results, the vehicle controller activates the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller.

[0092] After receiving the high-voltage request sent by the intelligent driving controller, the vehicle controller detects whether there is a high-voltage power-on trigger source. If not, the vehicle controller executes the vehicle high-voltage power-off.

[0093] The temperature of the intelligent driving controller is obtained, and the temperature of the intelligent driving controller is compared with a preset temperature threshold to obtain the comparison result;

[0094] Based on the comparison results, the vehicle controller activates the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller.

[0095] For other specific limitations regarding computer-readable storage media, please refer to the description of the liquid-cooled pre-start control method for intelligent driving controllers of new energy vehicles above, which will not be repeated here.

[0096] Those skilled in the art will understand that any references to memory, storage medium, or database in the above embodiments of this application may include non-volatile and / or volatile memory. Non-volatile memory may include read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), or flash memory.

After receiving the high-voltage request from the intelligent driving controller, the vehicle controller detects whether there is a high-voltage power-on trigger source. If not, the vehicle controller performs high-voltage power-off. It obtains the temperature of the intelligent driving controller and compares it with a preset temperature threshold to obtain a comparison result. Based on the comparison result, the vehicle controller starts the thermal management system to control the water pump and uses a second heating method to liquid cool the intelligent driving controller. This application is mainly used in the rapid start-up and remote parking scenarios of the cold start AVM (panoramic monitoring image system) of the intelligent driving controller. By judging whether the user intends to use the vehicle, if so, the pre-start completes the high voltage power supply of the whole vehicle in advance, so that the intelligent driving controller can quickly enter the standby working state, which greatly shortens the user's waiting time or even eliminates the waiting time, allowing the user to use the car's intelligent driving system at will.
