Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to an intelligent upper and lower high-voltage control system and method combined with user behavior recognition. Background Art

[0002] The existing intelligent high-voltage up and down technical solutions, combined with different scenario descriptions, can be roughly divided into the following two categories. For the high-voltage up scenario, users can directly control the high-voltage up of the entire vehicle on the mobile phone APP. After the user arrives at the vehicle with a legal key, he can directly open the door and get in the vehicle, shift gears and drive directly; the user can also use the remote control key or the door handle button unlocking device to unlock the vehicle. In some technical solutions, the user can complete the vehicle high-voltage up after the vehicle is high-voltage up, and in some technical solutions, the user must open the door to start the high-voltage up after unlocking, and the user can also shift gears and drive after completing the high-voltage up; when the user is in the vehicle and the vehicle is in the off-power state, the user can also step on the brakes or issue a high-voltage up voice command to control the high-voltage up of the entire vehicle.

[0003] For the high-voltage reduction scenario, users can operate the vehicle's soft switch or issue a high-voltage reduction voice command in the car to control the vehicle to reduce the high voltage. Users can also control the vehicle to reduce the high voltage after using the car. Some technical solutions control the vehicle to reduce the power after recognizing that there is no one in the driver's seat, the seat belt is unfastened, and the driver's door is opened and closed. Some technical solutions control the vehicle to reduce the power after recognizing that the vehicle is locked.

[0004] Existing new energy vehicles have the following defects when performing intelligent up and down high voltage functions. First, when the whole vehicle is high voltage, the user needs to unlock, open the door with a key, or use a mobile phone APP for remote control to turn on the high voltage. Second, when the whole vehicle needs to be lowered after the user finishes using the vehicle, the user needs to leave the vehicle and lock the vehicle before the vehicle can lower the high voltage. Third, for users who need to turn on and off the high voltage when using the vehicle, the current solution cannot execute the high voltage up and down actions required by the user in advance. In terms of user experience, the intelligent operation of the vehicle is not timely enough, which affects the experience. Summary of the invention

[0005] In view of the above problems, the present invention provides an intelligent upper and lower high voltage control system and method combined with user behavior recognition. The specific technical solution is as follows: An intelligent up and down high voltage control system combined with user behavior recognition, comprising: a main control ECU, a power system control, a driving gear control, a door lock system control, a brake system control, a key position recognition system, an external vehicle imaging system, a remote control system and a vehicle computer; the system control logic is: the power system control sends the vehicle high voltage state to the main control ECU, and receives the up and down high voltage control request sent by the main control ECU to control the vehicle up and down high voltage; the driving gear control sends the vehicle driving gear state to the main control ECU; the door lock system control sends the vehicle door state to the main control ECU, and receives the door lock control request sent by the main control ECU to control the vehicle unlocking; the brake system control sends the brake pedal state to the main control ECU; the key position recognition system sends the key position information to the main control ECU; the external vehicle imaging system sends the vehicle position information to the main control ECU; The remote control system sends the remote control up and down high voltage instructions to the main control ECU; the cockpit vehicle host sends the voice control up and down high voltage instructions and the soft switch control up and down high voltage instructions to the main control ECU; the main control ECU performs logical arbitration and processing based on all the information received and its own software strategy, and sends the following control signals: (1) Sends up and down high voltage control requests to the power system control to control the up and down high voltage of the entire vehicle; (2) Sends a door lock control request to the door lock system control to control the unlocking of the entire vehicle.

[0006] According to the control method of the above-mentioned control system, it includes an upper high-voltage control step and a lower high-voltage control step; in the upper high-voltage control, the user approaches the vehicle with a remote control key or a mobile phone key, and the vehicle recognizes that the straight-line distance between the user and the vehicle jumps from greater than X meters to less than or equal to X meters based on the key position, and the vehicle recognizes that the user has the intention to use the vehicle and automatically completes the upper high-voltage action; in the lower high-voltage control, after recognizing that the user has parked the car in the parking space and completed the action of switching the driving gear to P gear through the function of the external vehicle imaging system, the vehicle recognizes that the user has parked the car and has the intention to leave the car, and automatically completes the lower high-voltage action; if it is not recognized that the vehicle has not entered the parking space, but the vehicle driving gear is in P gear and all the doors are closed, and the user carries a legal key away from the vehicle, the vehicle recognizes that the straight-line distance between the user and the vehicle jumps from less than or equal to Y meters to greater than Y meters (Y>X) based on the key position, then the user also has the intention to leave the vehicle, and the vehicle automatically executes the lower high-voltage and vehicle locking actions.

[0007] Furthermore, the steps of high voltage control are as follows: Step 11: The process starts; Step 12: The precondition is that the vehicle is currently in a low-pressure state; Step 13.1: The user controls the high voltage of the vehicle through the mobile phone APP, and the process jumps to Step 16; Step 13.2: The user approaches the vehicle with a valid key. The vehicle can detect the key within Z meters of the key, and Z>Y. Step 13.3: The user presses high pressure on the in-car voice command control, and the process jumps to Step 16; Step 13.4: The user steps on the brake pedal and the process jumps to Step 16; Step 14: Determine the straight-line distance between the key and the vehicle; Step 15: Is the distance ≤ X meters? If so, the process proceeds to the next step, otherwise the process returns to Step 14; Step 16: The vehicle automatically performs the high-voltage action on the whole vehicle; Step 17: The process ends; Further, the steps of lower high pressure control are as follows: Step 21: The process starts; Step 22: The precondition is that the vehicle is currently in the upper high-voltage state; Step 23.1: The user controls the vehicle to lower the voltage through the mobile phone APP, and the process jumps to Step 29; Step 23.2: The user parks the vehicle in the parking space and shifts the vehicle into P gear, and the process jumps to Step 29; Step 23.3: The user presses high pressure under the voice command control in the car, and the process jumps to Step 29; Step 23.3: The vehicle is not in the parking space; Step 24: The user puts the vehicle into P gear and closes all the doors; Step 25: The user takes the legal key away from the vehicle; Step 26: Determine the straight-line distance between the key and the vehicle; Step 27: Is the distance greater than Y meters? If so, the process proceeds to the next step. If not, the process returns to Step 26. Step 28: The vehicle automatically performs locking action; Step 29: The vehicle automatically performs the high-voltage action of the whole vehicle; Step 210: The process ends.

[0008] The present invention is a new intelligent high-voltage control scheme that combines user driving behavior recognition, and has the following two innovative improvements. First, for the high-voltage scenario, the user only needs to carry the remote control key or mobile phone key to approach the vehicle. After the vehicle recognizes that the straight-line distance between the user and the vehicle jumps from greater than X meters to less than or equal to X meters based on the key position, the vehicle recognizes that the user has the intention to use the car, and can automatically complete the high-voltage action. Second, for the low-voltage scenario, with the help of the external imaging system function, the vehicle recognizes through the external camera that the user has parked the car in the parking space and completed the action of switching the driving gear to P gear. The vehicle recognizes that the user has parked the car and has the intention to leave the car, and can automatically complete the low-voltage action; if it is not recognized that the vehicle has not entered the parking space, but the vehicle driving gear is in P gear and all the doors are closed, the user carries a legal key away from the vehicle, and the vehicle recognizes that the straight-line distance between the user and the vehicle jumps from less than or equal to Y meters to greater than Y meters (Y>X) based on the key position, it is also considered that the user has the intention to leave the car, and the vehicle automatically performs the low-voltage and locks the vehicle action.

[0009] At the same time, some redundant upper and lower high-voltage solutions are retained to cover some special scenarios when users use the car. The technical solution of the present invention is aimed at normal user car use scenarios. The vehicle can recognize the user's intention to complete the upper and lower high-voltage actions in advance, greatly improving the user's intelligent car experience.
