[0026] When the vehicle is parked, the oil in the transmission may backflow or evaporate, making it easy for air to enter the uncovered oil passages, resulting in the vehicle being unable to respond to driver inputs in a timely manner. Therefore, when the clutch is actuated, the clutch needs to be primed. However, if the priming operation is performed after the vehicle is powered on or started, the time it takes may result in the vehicle being unable to respond to driver inputs in a timely manner, thus affecting the driving experience.

[0027] In addition, even if the driver opens the driver's door, sits in the driver's seat, steps on the brake pedal, or shifts the gear lever, he or she may not drive the car immediately. Therefore, if the clutch is filled with oil immediately after the driver's relevant operations are detected, the number of unnecessary fillings may increase, resulting in energy waste.

[0028] To solve the above problems, an embodiment of the present application provides a vehicle control method, which can respond to a first detection signal to perform a first oil filling operation, and respond to a second detection signal to perform a second oil filling operation, thereby pre-filling the oil before the vehicle is powered on or started. The air in the transmission oil circuit is discharged by oil filling, ensuring that the vehicle can respond to user operations in a timely manner, effectively improving the user's driving experience.

[0029] See Figure 1 FIG. 1 is a flow chart of a vehicle control method according to an embodiment of the present application. The vehicle control method is applied to a vehicle and includes: S101 , in response to a first detection signal, controlling an oil pump of a clutch of a vehicle to operate based on a preset speed to perform a first oil filling operation.

[0030] In one embodiment of the present application, the first detection signal is a signal generated in response to a first user operation. For example, the first detection signal is a driver's door opening signal, and the corresponding first user operation is opening the driver's door. The preset speed is lower than the speed of the oil pump during normal oil filling. For example, the speed of the oil pump during normal oil filling is 700 rpm, and the preset speed is 400 rpm, 500 rpm, 600 rpm, or another speed value. The specific value of the preset speed is not limited in this embodiment of the present application.

[0031] In one embodiment of the present application, a door sensor is provided on the driver's door for detecting whether the driver's door is opened. If so, a driver's door open signal is generated. The vehicle detects whether the door sensor generates a driver's door open signal in real time, that is, at predetermined intervals. If the driver's door open signal is detected, it is determined that the user intends to start the vehicle, and the oil pump is controlled to operate at a predetermined speed, that is, at a lower speed, to perform a first oil filling operation to fill the vehicle's clutch with oil, thereby preventing air from entering the clutch oil circuit and preventing the clutch from responding to user operations in a timely manner.

[0032] In another embodiment of the present application, a camera device is provided in the vehicle, which can capture images of the interior environment of the vehicle in real time. The camera device detects whether the driver's door is opened based on the captured image. If it is detected that the driver's door is opened, a driver's door opening signal is generated.

[0033] In another embodiment of the present application, it is also possible to analyze the image captured by the camera device to determine whether the user has a driving intention. For example, the image is input into a driving intention analysis model, and the image is analyzed by the driving intention analysis model to determine whether the user operation in the image has a driving intention. For example, if it is determined that the user opens the driver's door and enters the driver's seat, it is determined that the user has a driving intention, and then the corresponding refueling operation is performed. If it is determined that the user opens the driver's door to take an item, it is determined that the user has no driving intention, and the refueling operation is not performed. The driving intention analysis model is established by training multiple user operation images with driving intention and user operation images without driving intention as training data.

[0034] S102 , in response to the second detection signal, performing a second oil filling operation based on a first preset control method corresponding to the second detection signal.

[0035] In one embodiment of the present application, the second detection signal is a driver's seat belt sensing signal. For example, the second user operation corresponding to the driver's seat belt sensing signal is buckling the driver's seat belt.

[0036] See Figure 2 Figure 2 shows a schematic diagram of the structure of a vehicle transmission according to an embodiment of the present application. In one embodiment of the present application, the vehicle's clutch is controlled by a solenoid valve. For a clutch controlled by a solenoid valve, an oil pump provides system oil pressure, and the solenoid valve controls clutch pressure. When air is trapped in the control oil circuit, opening the solenoid valve expel the air, thereby improving the clutch's response speed.

[0037] In one embodiment of the present application, the first preset control method corresponding to the driver's seat belt sensing signal is to input a first preset number of pulse currents to the solenoid valve.

[0038] In one embodiment of the present application, the driver's seat is provided with a seatbelt buckle sensor for sensing whether the driver's seat belt is buckled. If the driver's seat belt buckle is sensed, that is, if someone is sitting in the driver's seat, a driver's seat belt sensing signal is generated. The vehicle detects the driver's seat belt sensing signal at preset intervals to determine whether the driver's seat belt sensing signal is detected. If the driver's seat belt sensing signal is detected, a second oil filling operation is performed by inputting a first preset number n1 of pulse current into the solenoid valve. The pulse speed corresponds to a preset speed value and a preset time interval, the current value of the pulse current is a preset current value I, and the pulse time interval of the pulse current is a preset time interval. For example, the first preset number n1 is 5, the preset current value I is 1200 milliamperes (mA), and the preset time interval is 20 milliseconds (ms). If the driver's seat belt sensing signal is not detected, no operation is performed.

[0039] In another embodiment of the present application, the camera device detects whether someone has buckled the driver's seat belt based on the captured image, and generates a driver's seat belt perception signal if it is detected that someone has buckled the driver's seat belt.

[0040] In another embodiment of the present application, an analysis of images captured by a camera device can be performed to determine whether the user has a driving intention. For example, the image is input into a driving intention analysis model, which analyzes the image to determine whether the user's actions in the image indicate a driving intention. For example, if it is determined that the user has not unbuckled the driver's seat belt within a certain period of time after buckling it, it is determined that the user has a driving intention, and the corresponding oil filling operation is performed. If it is determined that the user has unbuckled the driver's seat belt within a certain period of time after buckling it, it is determined that the user has no driving intention, and the oil filling operation is not performed.

[0041] The above-mentioned embodiment of the present application can perform one oil filling operation in response to the first detection signal and perform another oil filling operation in response to the second detection signal. The above two oil filling operations are performed before the vehicle is powered on or started, thereby pre-filling the vehicle with oil and expelling air from the transmission oil circuit, ensuring that the vehicle can respond to user operations in a timely manner, and effectively improving the user's driving experience.

[0042] See Figure 3 FIG. 1 is a flow chart of a vehicle control method according to another embodiment of the present invention. The vehicle control method is applied to a vehicle and includes: S201 , in response to a first detection signal, controlling an oil pump of a clutch of a vehicle to operate based on a preset speed to perform a first oil filling operation.

[0043] S202 , in response to the second detection signal, performing a second oil filling operation based on a first preset control method corresponding to the second detection signal.

[0044] The specific implementation of S201-S202 is the same as that of S101-S102, and will not be repeated here.

[0045] S203: If a third detection signal is generated after a first preset time period after the second oil filling operation is completed, a third oil filling operation is performed based on a second preset control method corresponding to the third detection signal.

[0046] In one embodiment of the present application, the third detection signal is a brake pedal signal, the third user operation corresponding to the brake pedal signal is stepping on the brake pedal, and the second preset control method corresponding to the brake pedal signal is inputting a second preset number of pulse currents to the solenoid valve.

[0047] In one embodiment of the present application, a brake pedal is provided with a pedal sensor for sensing whether the brake pedal is being pressed by sensing whether the brake pedal is under pressure, and for sensing whether the brake pedal is being released by sensing whether the brake pedal is no longer under pressure. If the brake pedal is under pressure, that is, it is sensed that the brake pedal is being pressed, a brake pedal pressed signal is generated. If the brake pedal is no longer under pressure, that is, it is sensed that the brake pedal is released, a brake pedal released signal is generated.

[0048] After detecting the driver's seat belt sensor signal, the system detects the brake pedal signal at predetermined intervals. It determines whether the brake pedal signal is detected after a first predetermined time period T1, after a first predetermined number of pulse currents are input to the solenoid valve. If the brake pedal signal is detected after the first predetermined time period T1, a second predetermined number n2 of pulse currents are input to the solenoid valve to initiate the second oil charging operation. For example, the first predetermined time period T1 is 2 minutes, and the second predetermined number n2 is 3. If the brake pedal signal is not detected after the first predetermined time period T1, no operation is performed.

[0049] In another embodiment of the present application, the camera device detects whether the brake pedal is stepped on based on the captured image, and generates a brake pedal stepping signal if it is detected that the brake pedal is stepped on.

[0050] In another embodiment of the present application, an analysis of images captured by a camera device can be performed to determine whether the user has a driving intent. For example, the image is input into a driving intent analysis model, which analyzes the image to determine whether the user's actions in the image indicate a driving intent. For example, if it is determined that the user has pressed the brake pedal to a certain height, it is determined that the user has a driving intent, and the corresponding oil filling operation is performed. If it is determined that the user has pressed the brake pedal but has not reached a certain height, it is determined that there is no driving intent, and it may be an accidental touch, and the oil filling operation is not performed.

[0051] S204 , if a fourth detection signal is generated after the second preset time period after the third oil filling operation is completed, perform a fourth oil filling operation based on a third preset control method corresponding to the fourth detection signal.

[0052] In one embodiment of the present application, the fourth detection signal is a shift lever signal, the fourth user operation corresponding to the shift lever signal is shifting the shift lever, and the third preset control method corresponding to the shift lever signal is inputting a third preset number of pulse currents to the solenoid valve.

[0053] In one embodiment of the present application, the shift lever is provided with a shift lever sensor for sensing whether the shift lever is moved. If the shift lever is sensed to be moved, a shift lever signal is generated.

[0054] After detecting the brake pedal signal, the shift lever signal is detected at a preset interval. A determination is made as to whether the shift lever signal is detected after a second preset time period T2, after a second preset number of pulse currents are input to the solenoid valve. If the shift lever signal is detected after the second preset time period T2, a third preset number n3 of pulse currents is input to the solenoid valve to perform the fourth oil charging operation. For example, the second preset time period T2 is 1.5 minutes, and the third preset number n3 is 2. If the shift lever signal is not detected after the second preset time period T2, no operation is performed.

[0055] In another embodiment of the present application, the camera device detects whether the shift lever is moved based on the captured image, and generates a shift lever moving signal if it is detected that the shift lever is moved.

[0056] In another embodiment of the present application, an analysis of images captured by a camera device can be performed to determine whether the user has a driving intent. For example, the image is input into a driving intent analysis model, which analyzes the image to determine whether the user's actions in the image indicate a driving intent. For example, if it is determined that the user has moved the shift lever by a certain amount, it is determined that the user has a driving intent, and the corresponding fuel filling operation is performed. If it is determined that the user has moved the shift lever but not by a certain amount, it is determined that there is no driving intent, which may be an accidental touch, and the fuel filling operation is not performed.

[0057] S205 , if a fifth detection signal is generated after the third preset time period after the fourth oil filling operation is completed, perform a fifth oil filling operation based on a fourth preset control method corresponding to the fifth detection signal.

[0058] In one embodiment of the present application, the fifth detection signal is a brake pedal release signal, the fifth user operation corresponding to the brake pedal release signal is releasing the brake pedal, and the fourth preset control method corresponding to the brake pedal release signal is inputting a fourth preset number of pulse currents to the solenoid valve.

[0059] After detecting the shift lever signal, the brake pedal release signal is detected at predetermined intervals. A determination is made as to whether the brake pedal release signal is detected after a third predetermined time period T3, after a third predetermined number of pulse currents are input to the solenoid valve. If the brake pedal release signal is detected after the third predetermined time period T3, a fourth predetermined number of pulse currents are input to the solenoid valve to perform the fifth oil charging operation. For example, the third predetermined time period T3 is 1 minute, and the fourth predetermined number n3 is 1. If the brake pedal release signal is not detected after the third predetermined time period T3, no operation is performed.

[0060] In another embodiment of the present application, the camera device detects whether the brake pedal is released based on the captured image, and generates a brake pedal release signal if it is detected that the brake pedal is released.

[0061] In another embodiment of the present application, an analysis of images captured by a camera device can be performed to determine whether the user has a driving intention. For example, the image is input into a driving intention analysis model, which analyzes the image to determine whether the user's actions in the image indicate a driving intention. For example, if it is determined that the user has fully released the brake pedal, it is determined that the user has a driving intention, and the corresponding oil filling operation is performed. If it is determined that the user has not fully released the brake pedal, it is determined that there is no driving intention, and the trigger may be an accidental release, and the oil filling operation is not performed.

[0062] In one embodiment of the present application, the operation of starting the vehicle includes a first user operation, a second user operation, a third user operation, a fourth user operation, and a fifth user operation. That is, when the user opens the driver's door, buckles the driver's seat belt, steps on the brake pedal, shifts the gear lever, and releases the brake pedal, the vehicle can be started.

[0063] In one embodiment of the present application, the vehicle's gearbox includes a control oil circuit for controlling the clutch. The control oil circuit can be filled with oil by performing an oil filling operation, thereby discharging air in the control oil circuit and improving the response speed of the clutch.

[0064] Based on the above embodiments of the present application, an oil filling operation is performed in response to the first detection signal, and another oil filling operation is performed in response to the second detection signal. The above two oil filling operations are performed before the vehicle is powered on or started, thereby pre-filling the vehicle with oil. When the interval between subsequent detection signals exceeds the preset time, the oil filling operation continues to be performed. When the interval between subsequent detection signals does not exceed the preset time, there is no need to perform the oil filling operation, thereby reducing the number of unnecessary oil fillings and avoiding energy waste. By filling the oil and expelling the air in the transmission oil circuit, the vehicle can be guaranteed to respond to user operations in a timely manner, effectively improving the user's driving experience.

[0066] Among them, if the driver's door opening signal generated by the door sensor is detected, it is determined that the driver's door is opened; if the driver's door opening signal generated by the door sensor is not detected, it is determined that the driver's door is not opened.

[0082] See Figure 5 Figure 2 is a schematic diagram of the structure of a vehicle transmission according to another embodiment of the present application. In another embodiment of the present application, the clutch is controlled by an oil pump. For a clutch controlled by an oil pump, the oil pump provides system oil pressure and directly controls clutch pressure, which can expel air from the control oil circuit, thereby improving the clutch's response speed.

[0083] In another embodiment of the present application, the second detection signal is a driver's seat belt sensing signal, and the first preset control method corresponding to the driver's seat belt sensing signal is to control the oil pump to operate at a first preset number of pulse speeds.

[0084] The vehicle detects a driver's seat belt sensor signal at predetermined intervals and determines whether the driver's seat belt sensor signal is detected. If the driver's seat belt sensor signal is detected, the oil pump is controlled to operate at a first predetermined number of pulse speeds to perform a second oil filling operation. The pulse speed is a predetermined speed value N, and the pulse intervals are predetermined intervals. For example, the first predetermined number n1 is 5, the predetermined speed value N is 700 rpm, and the predetermined interval is 20 milliseconds (ms). If the driver's seat belt sensor signal is not detected, no operation is performed.

[0085] In another embodiment of the present application, the third detection signal is a brake pedal signal, and the second preset control mode corresponding to the brake pedal signal is to control the oil pump to operate at a second preset number of pulse speeds.

[0086] After detecting the driver's seat belt sensor signal, the system detects the brake pedal signal at predetermined intervals. It determines whether the brake pedal signal is detected after the oil pump is controlled to operate at a first predetermined number of pulse speeds for a first predetermined duration T1. If the brake pedal signal is detected within the first predetermined duration T1, the oil pump is controlled to operate at a second predetermined number of pulse speeds to perform a third oil filling operation. For example, the first predetermined duration T1 is 2 minutes, and the second predetermined number n2 is 3. If the brake pedal signal is not detected within the first predetermined duration T1, no operation is performed.

[0087] In another embodiment of the present application, the fourth detection signal is a shift lever signal, and the third preset control mode corresponding to the shift lever signal is to control the oil pump to operate at a third preset number of pulse speeds.

[0088] After detecting the brake pedal signal, the shift lever signal is detected at a preset interval. A determination is made as to whether the shift lever signal is detected after a second preset time duration T2, during which the oil pump is controlled to operate at a second preset number of pulse speeds. If the shift lever signal is detected after the second preset time duration T2, the oil pump is controlled to operate at a third preset number of pulse speeds, and the fourth oil charging operation is performed. For example, the second preset time duration T2 is 1.5 minutes, and the third preset number n3 is 2. If the shift lever signal is not detected after the second preset time duration T2, no operation is performed.

[0089] In another embodiment of the present application, the fifth detection signal is a brake pedal release signal, and the fourth preset control mode corresponding to the brake pedal release signal is to control the oil pump to operate at a fourth preset number of pulse speeds.

[0090] After detecting the shift lever signal, the brake pedal release signal is detected at predetermined intervals. A determination is made as to whether the brake pedal release signal is detected after a third predetermined time duration T3, during which the oil pump is controlled to operate at a third predetermined number of pulse speeds. If the brake pedal release signal is detected after the third predetermined time duration T3, the oil pump is controlled to operate at a fourth predetermined number of pulse speeds, executing the fifth oil charging operation. For example, the third predetermined time duration T3 is 1 minute, and the fourth predetermined number n3 is 1. If the brake pedal release signal is not detected after the third predetermined time duration T3, no operation is performed.
