[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] See also Figure 1 , is a schematic diagram of the structure of a control device for a car wash scenario provided by an embodiment of the present invention, wherein the control device includes a safety response module, a cabin domain controller IDCM, a power domain controller VDCM, and a body domain controller BDCM;

[0038] The cockpit domain controller IDCM, power domain controller VDCM and body domain controller BDCM are all connected to the safety response module; the power domain controller VDCM and body domain controller BDCM are also connected to the cockpit domain controller IDCM;

[0039] The IDCM (Cockpit Domain Controller) is connected to the central control screen, secondary screen, and various control buttons in the vehicle. Users can input various control commands through the central control screen, secondary screen, and control buttons. The IDCM responds to the user input commands and feeds them back to the VDCM (Powertrain Domain Controller) and the BDCM (Body Domain Controller).

[0040] The body domain controller BDCM is mainly configured to control electric doors, windows, electric rearview mirrors, air conditioning, headlights, turn signals, anti-theft locking system, central locking, defrost device, etc.

[0041] The power domain controller VDCM is an intelligent powertrain management unit, which is mainly configured for powertrain optimization and control, while also having functions such as electrical intelligent fault diagnosis, intelligent power saving, and bus communication.

[0042] The cockpit domain controller (IDCM) is configured to implement complex electronic cockpit functions such as multi-screen linkage and multi-screen driving. The IDCM monitors user control commands and, upon detecting a control command input, generates and sends a mode start command to the power domain controller (VDCM) and the body domain controller (BDCM).

[0043] After receiving the mode start instruction, the power domain controller VDCM executes the preset first car wash mode instruction; after receiving the mode start instruction, the body domain controller BDCM executes the preset second car wash mode instruction to control the vehicle power and body control to enter the state controlled by the car wash mode instruction, and the vehicle enters the car wash mode.

[0044] After the vehicle enters the car wash mode, the safety response module detects the vehicle status, that is, monitors the bus signals fed back by the cockpit domain controller, the power domain controller, and the body domain controller; the bus signals are vehicle status signals determined by the cockpit domain controller, the power domain controller, and the body domain controller after analyzing the status of each sensor or controller of the vehicle body.

[0045] The present invention eliminates the central gateway of the vehicle controller and adopts the cockpit domain controller to identify user instructions and feed back signals to other domain controllers, thereby reducing costs and improving transmission efficiency.

[0046] The safety response module searches for control instructions corresponding to the bus signal from a preset abnormal scenario control instruction library based on the bus signal, and controls the cockpit domain controller, the power domain controller and the body domain controller according to the searched control instructions to ensure vehicle safety performance.

[0047] The cockpit domain controller, power domain controller and body domain controller execute corresponding instructions, control the vehicle's response devices to enter the corresponding state, and the vehicle automatically enters the car wash mode; and the bus signal is detected through the safety response module to ensure the safety performance of the vehicle in the car wash mode.

[0048] In another embodiment of the present invention, the cockpit domain controller generates and sends a mode start signal to the power domain controller and the body domain controller in response to a control instruction input by a user, specifically comprising:

[0049] In response to a control instruction input by a user, obtaining a first verification code in the control instruction;

[0050] When the acquired first verification code is identical to the first instruction code preset by the user, it is determined that the first verification code verification has passed, and a mode start signal is generated and sent to the power domain controller and the body domain controller.

[0051] In the specific implementation of this embodiment, when the body domain controller detects that the user triggers the button to enter the car wash mode, it feeds back a message that a verification code is required to the corresponding control screen, and receives a control instruction containing the first verification code input by the user;

[0052] Obtaining a first verification code input by a user, and comparing the first verification code with a preset first instruction code;

[0053] When the first verification code is identical to the first instruction code, the first verification code verification is determined to have failed, a message is fed back to the user requesting the user to re-enter the first verification code, and the first verification code entered by the user is detected again and re-evaluated until the first verification code entered by the user is identical to the first instruction code or the number of verification code entries by the user reaches a preset threshold;

[0054] When the first verification code is identical to the first instruction code, it is determined that the first verification code verification is passed, and a mode start signal is generated and sent to the power domain controller and the body domain controller.

[0055] When the number of times the user enters the verification code reaches a preset threshold, the vehicle is locked.

[0056] By comparing the verification code, it is determined that the car wash mode control instruction is a user operation, avoiding the safety hazards caused by misoperation or other people operating the vehicle to enter the car wash mode.

[0057] It should be noted that the first verification code may be a PIN code, or other verification information input by the user that can prove the identity information, including fingerprint or voiceprint.

[0058] In another embodiment provided by the present invention, the cockpit domain controller is further configured to respond to a control instruction input by a user and execute a preset first car wash mode instruction to turn off the vehicle voice recognition function, turn off the vehicle's secondary screen, and turn off the automatic opening function of the secondary screen;

[0059] The cockpit domain controller is also configured to respond to an R gear signal input and turn on the vehicle's 360-degree panoramic image.

[0060] When implementing this embodiment, see Figure 2 , is a structural diagram of a control device for a car wash scene provided by another embodiment of the present invention. The cockpit domain controller IDCM is connected to the central control screen and the secondary screen to realize the display function of the control screen and the secondary screen, and detect the vehicle control signals input by the central control screen and the secondary screen, and feed back the response control signals to the power domain controller and the body domain controller to realize the corresponding functions.

[0061] The cockpit domain controller turns off the voice recognition and voice control functions in the vehicle in response to the user's control instructions.

[0062] Specifically: responding to a control instruction input by a user, obtaining a first verification code in the control instruction;

[0063] When the obtained verification code is the same as the instruction code pre-set by the user, a control signal is sent to the vehicle's central control screen or sub-screen to configure the voice detection unit, turn off the voice detection function of the voice detection unit, and thus turn off the vehicle's voice recognition function; when the vehicle enters the car wash mode, the cockpit domain controller automatically turns off the vehicle's voice recognition function to avoid the corresponding function being mistakenly triggered by voice input by non-vehicle users in the car wash mode.

[0064] Control the automatic opening function of the vehicle. At present, the secondary screen of most vehicles on the market has an automatic opening function. After the vehicle is started, the secondary screen automatically opens, and after the vehicle is locked, the secondary screen automatically closes;

[0065] In car wash mode, turn off the vehicle's secondary screen and disable the secondary screen's automatic opening function to protect the vehicle's privacy in car wash mode;

[0066] When the vehicle is in car wash mode, the car washer needs to move the vehicle after washing, and may need to reverse. The cockpit controller is used to detect the gear information of the vehicle when the vehicle is in car wash mode. When the vehicle's R gear signal is detected, that is, the vehicle is in reverse gear, a 360-degree panoramic image of the vehicle is overlaid on the vehicle's central control screen, which protects the user's privacy in car wash mode while ensuring the safety of moving the vehicle when reversing.

[0067] In another embodiment provided by the present invention, the power domain controller is configured to respond to the transmission mode start signal sent by the cockpit domain controller, execute the preset second car wash mode instruction, so as to control the battery management system of the vehicle to remain powered on, and limit the motor speed to not exceed the set value through the vehicle motor controller.

[0068] When implementing this embodiment, see Figure 2The power domain controller VDCM is connected to the vehicle's battery management system BMS and motor controller, and is configured to control the power output of the vehicle's battery and motor.

[0069] When the power domain controller VDCM receives the control signal from the cockpit domain controller, it executes the preset second car wash mode command, controls the vehicle's battery management system BMS to keep it powered on, and limits the motor speed to no more than the set value through the motor controller;

[0070] The power domain controller controls the vehicle's motor to remain powered in car wash mode, allowing car washers to shift gears and move the vehicle during the wash process. However, by limiting the motor speed, the vehicle speed is limited to 40 km / h. This makes it easier for car washers to control the vehicle without the need for users to accompany the car wash process, thereby improving the user's car experience.

[0071] In another embodiment provided by the present invention, the body domain controller is configured to respond to the sending mode start signal sent by the cockpit domain controller and execute a preset third car wash mode instruction to turn off the automatic locking function of the door controller, turn off the brake automatic door closing function of the door controller, turn off the door follow-up switch function of the door controller, lock the vehicle's charging port, turn off the automatic wiping function of the wiper controller, turn off the vehicle air conditioner, and turn off the lights.

[0072] When implementing this embodiment, see Figure 2 The body domain controller BDCM is connected to the wiper controller, digital headlights, and the left front door controller DCM-FL, right front door controller DCM-FR, left rear door controller DCM-RL, and right rear door controller DCM-RR to control the wipers, headlights, and doors to enter the preset state, and the vehicle enters the car wash mode;

[0073] Among them, the four door controllers are equipped with an automatic locking function, which is used to automatically lock the vehicle's doors, windows and trunk when the vehicle's sensor key is away from the vehicle at a certain distance;

[0074] The wiper controller is configured with an automatic wiper function, which is used to automatically turn on the wipers when the sensor configured on the front windshield detects rain;

[0075] After receiving the transmission mode start signal sent by the cockpit domain controller, the body domain controller executes the preset third car wash mode command and sends a control command to the door controller to disable the automatic locking function configured by the door controller, disable the brake automatic door closing function of the door controller, disable the door follow-up switch function of the door controller, and lock the vehicle's charging port;

[0076] The vehicle's door controller has a brake-activated automatic door closing function, and the door's follow-up switch can control the opening and closing of the door. In car wash mode, these functions are turned off to avoid the problem of the door being locked due to accidental touch by the car washer.

[0077] It also locks the vehicle's charging port to prevent the car washer from accidentally touching and pressing the automatic opening port, which could cause water to enter the vehicle's charging port during car wash mode and cause damage.

[0078] Send a control command to the wiper controller to turn off the automatic wiper function of the wiper; send a control command to the vehicle air conditioning controller to turn off the vehicle air conditioning; send a control command to the digital headlights to control the digital headlights to turn off;

[0079] Through the body domain controller, the vehicle is controlled to enter automatic mode, the automatic locking function is turned off to avoid locking the car washer in the car, and it is also convenient for the car washer to clean the interior decoration of the car; the automatic wiper function is turned off to avoid the automatic wipers working automatically during washing, affecting the car washing process; the air conditioner and headlights are turned off to reduce unnecessary energy loss of the vehicle.

[0080] In another embodiment provided by the present invention, the cockpit domain controller is connected to the security response module via a wireless gateway.

[0081] When implementing this embodiment, see Figure 2 , the security response module and the cockpit domain controller are connected through a wireless gateway T-BOX; the cockpit domain controller and the security response module are connected through the network, supporting different protocol conversions to ensure stable communication between the security response module and the cockpit domain controller;

[0082] In addition, it should be noted that the power domain controller and the body domain controller can be connected to the security response module through a wireless gateway to detect the bus signals on the power domain controller, the body domain controller and the cockpit domain controller.

[0083] In another embodiment provided by the present invention, controlling the cockpit domain controller, the power domain controller, and the body domain controller according to the control instructions corresponding to the bus signal matched from a preset abnormal scenario control instruction library specifically includes:

[0084] When the bus signal is an abnormal crash signal sent by the cockpit domain controller, a first control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller, thereby controlling the vehicle to exit the car wash mode and controlling the automatic locking of the door controller;

[0085] When the bus signal is a small battery feeding signal sent by the power domain controller, the second control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller to control the vehicle to exit the car wash mode and control the automatic locking of the door controller;

[0086] When the bus signal is a low battery signal sent by the power domain controller, a third control instruction is executed to maintain the signal to the cockpit domain controller, the power domain controller, and the body domain controller in a feedback mode, so as to control the vehicle to maintain the car wash mode;

[0087] When the bus signal is an application abnormality signal sent by the cockpit domain controller, a fourth control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller, thereby controlling the vehicle to exit the car wash mode and controlling the automatic locking of the door controller;

[0088] When the bus signal is a communication failure signal sent by the cockpit domain controller, a fifth control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller, thereby controlling the vehicle to exit the car wash mode and controlling the automatic locking of the door controller;

[0089] When the bus signal is an account switching signal sent by the cockpit domain controller, the sixth control instruction is executed to feedback the mode exit signal to the cockpit domain controller, the power domain controller and the body domain controller to control the vehicle to exit the car wash mode and control the automatic locking of the door controller.

[0090] In the specific implementation of this embodiment, the safety response module is also connected to four door controllers;

[0091] The security response module is configured as follows:

[0092] Monitoring bus signals fed back by the cockpit domain controller, the power domain controller, and the body domain controller, and determining whether the detected bus signals correspond to control instructions in a preset abnormal scenario control instruction library, wherein the abnormal scenario control instruction library contains one-to-one correspondence between bus signals and control instructions;

[0093] When the detected bus signal is not a bus signal corresponding to the control instruction in the abnormal scenario control instruction library, the car wash mode of the vehicle is normal and the car wash mode is maintained;

[0094] When the detected bus signal is a bus signal corresponding to a control instruction in the abnormal scenario control instruction library, an abnormality occurs in the car wash mode and needs to be processed;

[0095] At this time, the abnormal scenario control instruction library matches the control instruction corresponding to the monitored bus signal, and controls the cockpit domain controller, power domain controller, body domain controller and door according to the instruction, specifically:

[0096] When the bus signal is an abnormal crash signal sent by the cockpit domain controller, a first control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller to control the vehicle to exit the car wash mode and control the doors to automatically lock through the door controller;

[0097] When the bus signal is a small battery feeding signal sent by the power domain controller, the second control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller to control the vehicle to exit the car wash mode and control the door to be automatically locked through the door controller;

[0098] When the bus signal is a low battery signal sent by the power domain controller, a third control instruction is executed to maintain the signal to the cockpit domain controller, the power domain controller, and the body domain controller in a feedback mode, so as to control the vehicle to maintain the car wash mode;

[0099] When the bus signal is an application abnormality signal sent by the cockpit domain controller, a fourth control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller to control the vehicle to exit the car wash mode and control the doors to automatically lock through the door controller;

[0100] When the bus signal is a communication failure signal sent by the cockpit domain controller, a fifth control instruction is executed to feedback a mode exit signal to the cockpit domain controller, the power domain controller, and the body domain controller to control the vehicle to exit the car wash mode and control the doors to automatically lock through the door controller;

[0101] When the bus signal is an account switching signal sent by the cockpit domain controller, the sixth control instruction is executed, and a feedback mode exit signal is sent to the cockpit domain controller, the power domain controller and the body domain controller to control the vehicle to exit the car wash mode, and control the door to automatically lock through the door controller.

[0102] The safety response module executes corresponding control instructions based on the monitored bus signals. When the vehicle is abnormal, it exits the car wash mode and automatically locks the doors to protect the vehicle safety. When the vehicle battery is low, the car wash process is avoided and the car wash mode is maintained to ensure the normal operation of the car wash mode.

[0103] In another embodiment provided by the present invention, the cockpit domain controller is further configured as follows:

[0104] In response to a mode-off signal input by a user, obtaining a second verification code in the mode-off signal;

[0105] When the acquired second verification code is identical to the second instruction code preset by the user, it is determined that the second verification code verification has passed, and a control signal is generated and sent to the power domain controller and the body domain controller to make the vehicle exit the car wash mode.

[0106] In the specific implementation of this embodiment, when the body domain controller detects that the user triggers the button to exit the car wash mode, it feeds back a message that a verification code is required to the corresponding control screen, and receives a control instruction containing a second verification code input by the user;

[0107] Obtaining a second verification code input by the user, and comparing the second verification code with a preset second instruction code;

[0108] When the second verification code is identical to the second instruction code, the second verification code verification is determined to have failed, a message is fed back to the user requesting the second verification code to be re-entered, and the second verification code entered by the user is detected and re-evaluated until the second verification code entered by the user is identical to the second instruction code or the number of verification code entries by the user reaches a preset threshold;

[0109] When the second verification code is identical to the second instruction code, it is determined that the second verification code verification is passed, and a mode closing signal is generated and sent to the power domain controller and the body domain controller.

[0110] When the number of times the user enters the verification code reaches a preset threshold, the vehicle is locked.

[0111] By comparing the verification code, it is determined that the car wash mode control instruction is a user operation, avoiding misoperation or other people operating the vehicle to exit the car wash mode, which brings inconvenience to the car wash process.

[0112] It should be noted that the second verification code may be a PIN code, or other verification information input by the user that can prove the identity information, including fingerprint or voiceprint.

[0113] In another embodiment of the present invention, the inputting process of the first verification code, the second verification code, the first instruction code and the second instruction code includes:

[0114] The user inputs via the central control screen connected to the cockpit domain controller, or,

[0115] The user inputs through a device that is communicatively connected to the cockpit domain controller.

[0116] In the specific implementation of this embodiment, the user can pre-set the first instruction code and the second instruction code using a central control screen, a secondary screen connected to the cockpit domain controller, or an external device that is connected to the cockpit domain controller and has passed verification;

[0117] The first instruction code and the second instruction code may be set to be the same or different; during specific execution, the first instruction code may be automatically set to be the same as the second instruction code, thereby reducing user operations.

[0118] When turning on or off the car wash mode, the user can input the first verification code and the second verification code through the central control screen, the secondary screen, or the external device connected to the cockpit domain controller to control the car wash mode;

[0119] By comparing the verification code with the instruction code, the vehicle safety performance is improved.
