Description

Vehicle power-on control method and device, electric commercial vehicle and storage medium TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle power-on control, in particular to a vehicle power-on control method and device, an electric commercial vehicle and a storage medium. BACKGROUND

[0002] The existing power-on control method of a pure electric commercial vehicle mainly detects whether the vehicle meets the high-voltage power-on condition through a hybrid control unit (HCU), and allows the vehicle to be powered on only when the condition is met. One of the conditions for high-voltage power-on is that the gearshift of the transmission is in neutral.

[0003] In actual use, the driver of the pure electric commercial vehicle may sometimes forget to return the gearshift to neutral, but the transmission controller itself has an automatic neutral return function, that is, it will actively return the transmission gearshift to neutral after detecting that the vehicle is powered on. Generally, the transmission gearshift return process is as follows: the transmission control unit (TCU) uses the time of the last low-voltage power-off and the time of the next low-voltage power-on to control the return of the transmission gearshift to neutral. However, in some cases, the transmission gears are tightly meshed, and the torque provided by the shift actuator itself cannot complete the shift operation independently, and a small torque is needed to complete the transmission gearshift and neutral return operation. If the TCU fails to automatically return the gearshift to neutral after power-off, the driver will try to power on again, but since the TCU gearshift is not in neutral, the vehicle will determine that the high-voltage power-on condition is not met and will not allow high-voltage power-on. In a low-voltage environment, the motor cannot respond to the command to provide a shaking torque to assist the TCU in completing the shift, resulting in the technical problem of the vehicle being unable to power on.

[0004] Therefore, it is necessary to provide a vehicle power-on control method, device, electric commercial vehicle and storage medium to achieve the purpose of high-voltage power-on of the vehicle when the transmission gearshift is not in neutral. SUMMARY

[0005] Therefore, it is necessary to provide a vehicle power-on control method, device, electric commercial vehicle and storage medium to achieve the purpose of high-voltage power-on of the vehicle when the transmission gearshift is not in neutral.

[0019] In a possible implementation, when the mode of the vehicle is the intelligent neutral return mode, the gearbox controller is controlled not to respond to the control instruction of the vehicle controller.

[0038] Reference to "an embodiment" in this document means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative embodiments to other embodiments. It is explicitly and implicitly understood by a person skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] The present application provides a vehicle power-on control method and device, an electric commercial vehicle and a storage medium, which are described below respectively.

[0040] Before the specific embodiments are displayed, the vehicle is introduced. The vehicle in the embodiments of the present application includes a transmission control unit (TCU) and a hybrid control unit (HCU). The transmission control unit is a transmission device capable of automatic gear shifting control according to the vehicle speed and engine speed. The hybrid control unit and the transmission control unit communicate through CAN. The hybrid control unit is used to send control instructions to the transmission control unit and receive feedback signals from the transmission control unit.

[0041] The vehicle further includes a motor control unit (MCU) and a battery management system (BMS) and other devices, which are not described here.

[0042] FIG. 1 is a flowchart of an embodiment of the vehicle power-on control method provided by the present application. As shown in FIG. 1, the vehicle power-on control method includes:

[0043] S101, when detecting a vehicle power-on request, determining whether the transmission gear position is in neutral;

[0044] S102, when the transmission gear position is not in neutral, controlling the transmission control unit to send a virtual neutral signal to the hybrid control unit, so that the hybrid control unit completes the vehicle high-voltage power-on based on the virtual neutral signal.

[0045] In step S101, the vehicle power-on request initiation mode can be: switching the key from the Off position to the On position.

[0046] It should be noted that the transmission gear position in neutral is only one condition for vehicle high-voltage power-on. In order to achieve the success rate and safety of vehicle high-voltage power-on, in some embodiments of the present application, after the hybrid control unit receives the virtual neutral signal, it also needs to judge other high-voltage power-on conditions. When all high-voltage power-on conditions are met, the vehicle high-voltage power-on is performed.

[0047] The high-voltage power-on conditions include but are not limited to: the motor control unit initialization is completed, the battery management system initialization is completed, the key is in the On position, the system has no high-voltage power-on prohibition fault, the direct current charging is not connected, the alternating current charging is not connected, the accelerator pedal is not stepped on, and the brake pedal is stepped on.

[0048] It should be noted that: before step S102, the vehicle needs to be powered on at low voltage, specifically: the low voltage power-on process is: the vehicle controller controls the vehicle main relay to close, and the power battery (for example, a 12V storage battery) supplies power to each controller (such as a battery management system and a motor controller) and low-voltage electrical devices. After low-voltage power-on, each controller begins initialization and completes self-checking. Taking the self-checking of the motor controller as an example: after the vehicle controller initialization is completed, the vehicle controller sends a request (i.e. sends an instruction to enter a low-voltage state to the motor controller) to the motor controller to enter a low-voltage state, if the motor controller is fault-free, it will respond to the mode request of the vehicle controller to enter a low-voltage state, and feedback low-voltage state information to the vehicle controller, if the motor controller has a fault, it will send the corresponding fault information to the vehicle controller, and light up the corresponding fault indicator on the instrument.

[0049] It should be noted that during the low-voltage power-on process, the vehicle cannot be driven, and the high-voltage electrical devices cannot work. In addition, after the low-voltage power-on is completed, the instrument should display the current power battery SOC, the gear state of the vehicle, the cruising range, the average energy consumption and other information.

[0050] Compared with the prior art, the vehicle power-on control method provided by the embodiment of the application controls the transmission controller to send a virtual neutral signal to the vehicle controller when the transmission gear is not in neutral, so that the vehicle controller can complete the vehicle high-voltage power-on based on the virtual neutral signal. That is: when the transmission controller is not in neutral, the vehicle high-voltage power-on can also be performed, achieving the purpose of vehicle power-on foolproofing.

[0051] Since the vehicle high-voltage power-on requires the vehicle to be powered on in a stationary / parked state, if the vehicle is in a running state when the vehicle high-voltage power-on is performed, a safety risk will occur. In a specific application scenario, when the handle gear is not in neutral, the vehicle will idle after the vehicle is powered on, causing safety problems. In order to avoid this technical problem, in some embodiments of the application, as shown in FIG. 2, the vehicle power-on control method further comprises:

[0052] S201, acquiring the handle gear and determining whether the handle gear is in the handle neutral position;

[0053] S202, when the handle gear is in the handle neutral position and the transmission controller detects a vehicle power-on request but the transmission gear is not in the neutral position, controlling the transmission controller to send a virtual neutral signal to the vehicle controller.

[0054] The embodiment of the present application ensures that the handle gear position is located at the handle neutral position, and then controls the transmission controller to send the virtual neutral signal to the vehicle controller, avoids that the handle gear position is located at the non-neutral position when the vehicle high voltage is powered on, the vehicle idles and moves, and causes a safety accident, and improves the safety of the vehicle power-on process.

[0055] In step S201, the handle gear position is obtained by obtaining the position signal of the handle based on the position sensor and determining the handle gear position based on the position signal of the handle.

[0056] It should be noted that when the handle gear position is not located at the handle neutral position in step S201, the vehicle controller is controlled to send a prompt information to the instrument to prompt the driver to switch the handle gear position to the handle neutral position, and then step S202 is executed.

[0057] Further, in the actual running scene of the vehicle, there is a specific scene of neutral coasting, that is, the handle gear position is neutral, but the vehicle is not in a stationary state, in order to avoid the technical problem of unsafe driving in this scene, in some embodiments of the present application, as shown in FIG. 3, the vehicle power-on control method further comprises:

[0058] S301, obtaining the motor speed of the motor and determining whether the motor speed is less than a threshold speed;

[0059] S302, when the motor speed is less than the threshold speed and the transmission controller detects the vehicle power-on request but the transmission gear position is not located at the neutral position, controlling the transmission controller to send the virtual neutral signal to the vehicle controller.

[0060] The embodiment of the present application ensures that the handle gear position is located at the handle neutral position, and then controls the transmission controller to send the virtual neutral signal to the vehicle controller, avoids that the handle gear position is located at the non-neutral position when the vehicle high voltage is powered on, the vehicle idles and moves, and causes a safety accident, and improves the safety of the vehicle power-on process.

[0061] In step S301, the motor speed is obtained based on the speed sensor.

[0062] The threshold speed can be set according to actual needs, and in the specific embodiment of the present application, the threshold speed is 100 rpm.

[0063] It should be noted that in order to maximize the safety of the vehicle power-on process, when the handle gear position is located at the handle neutral position, the motor speed is less than the threshold speed, and the transmission controller detects the vehicle power-on request but the transmission gear position is not located at the neutral position, the transmission controller is controlled to send the virtual neutral signal to the vehicle controller.

[0064] Through the above setting, the vehicle is ensured to be in a stop state when the whole vehicle is powered on, so as to realize safe whole vehicle power-on.

[0065] After the whole vehicle is powered on, the transmission controller not in the neutral position needs to be controlled to return to the neutral position, therefore, in some embodiments of the present application, the vehicle further comprises a motor and a transmission, and as shown in FIG. 4, after step S102, the vehicle further comprises:

[0066] S401, controlling the whole vehicle controller to send a motor enable instruction to the motor;

[0067] S402, based on the motor enable instruction, controlling the transmission controller to send a motor jitter torque instruction to the motor, so that the transmission returns to the neutral position based on the jitter torque.

[0068] In the embodiments of the present application, the whole vehicle controller sends a motor enable instruction to the motor, so as to wake up the motor, and the motor can provide a jitter torque based on the motor jitter torque instruction sent by the transmission controller, the jitter torque can make the transmission gear more easily disengage, so that the return to the neutral position operation is completed, and the efficiency and success rate of the return to the neutral position are improved.

[0069] The jitter torque is a sawtooth wave, and the torque oscillates in a short time. In the process of the jitter torque from positive zero to negative or from negative zero to positive, once the torque passes the “zero point”, the transmission controller can quickly complete the return to the neutral position, that is, the transmission controller can return to the neutral position more quickly and more smoothly. In this way, the safety of the transmission clutch in the return to the neutral position is ensured, and the execution time of the return to the neutral position is shortened, and the efficiency of the return to the neutral position is improved.

[0070] In order to make the vehicle controllers know the whole vehicle high-voltage power-on performed under the condition of the current virtual neutral signal being sent, avoid confusion with the normal whole vehicle high-voltage power-on, and cause unclear decision-making technical problems, in some embodiments of the present application, in the process of the transmission controller sending the virtual neutral signal to the whole vehicle controller to the whole vehicle controller completing the high-voltage power-on, the vehicle is controlled to enter an intelligent return to neutral position mode, and when the transmission controller returns to the neutral position based on the jitter torque, the vehicle is controlled to exit the intelligent return to neutral position mode.

[0071] In the embodiments of the present application, the vehicle is endowed with the intelligent return to neutral position mode, it is identified that the current whole vehicle high-voltage power-on is performed based on the virtual neutral signal, a basis is provided for the decision-making of the whole vehicle controller or the transmission controller, and the safety of the whole vehicle power-on process is further improved.

[0072] Since the virtual neutral signal is virtual, the actual gear of the gearbox controller is not located at the neutral gear, so as to avoid that the actual gear of the gearbox controller is not located at the neutral gear, the control instruction of the vehicle controller is responded, and a safety accident occurs, in some embodiments of the present application, when the mode of the vehicle is the intelligent return neutral mode, the gearbox controller is controlled not to respond to the control instruction of the vehicle controller.

[0073] In the embodiments of the present application, when the mode of the vehicle is the intelligent return neutral mode, the gearbox controller is controlled not to respond to the control instruction of the vehicle controller, so as to avoid that the gearbox controller responds under the influence of the control instruction, that is, the high-voltage power-on action is performed under the condition that the high-voltage power-on is not met, and a safety accident occurs, thereby further improving the safety during the vehicle power-on process.

[0074] The control instruction includes but is not limited to a torque instruction and a speed instruction.

[0075] Since the virtual neutral signal is a simulated actual neutral signal issued when the gearbox gear is located at the neutral gear, in order to ensure the reliability of the high-voltage power-on of the vehicle, the virtual neutral signal is completely consistent with the actual neutral signal.

[0076] That is, for the vehicle controller, the virtual neutral signal is completely consistent with the actual neutral signal, so that the vehicle controller can complete the high-voltage power-on of the vehicle after receiving the virtual neutral signal.

[0077] Specifically, the signal type, signal value and signal format of the virtual neutral signal and the actual neutral signal are completely same.

[0078] In order to better implement the vehicle power-on control method in the embodiments of the present application, on the basis of the vehicle power-on control method, correspondingly, the embodiments of the present application also provide a vehicle power-on control device, the vehicle includes a gearbox controller and a vehicle controller, as shown in FIG. 5, the vehicle power-on control device 500 includes:

[0079] The gear judgment unit 501 is used for judging whether the gearbox gear is located at the neutral gear when detecting the vehicle power-on request.

[0080] The high-voltage power-on unit 502 is used for controlling the gearbox controller to send a virtual neutral signal to the vehicle controller when the gearbox gear is not located at the neutral gear, so that the vehicle controller completes the high-voltage power-on of the vehicle based on the virtual neutral signal.

[0081] The vehicle power-on control device provided by the embodiment of the present application controls the transmission controller to send a virtual neutral signal to the vehicle controller when the transmission gear is not in the neutral position, so that the vehicle controller can complete the vehicle high-voltage power-on based on the virtual neutral signal. That is, when the transmission controller is not in the neutral position, the vehicle high-voltage power-on can also be performed, thereby achieving the purpose of preventing the vehicle power-on from being mistaken.

[0082] To improve the safety during the vehicle high-voltage power-on process, in some embodiments of the present application, the high-voltage power-on unit 502 is specifically configured to acquire the handle gear position and determine whether the handle gear position is in the handle neutral position; when the handle gear position is in the handle neutral position and the transmission controller detects a vehicle power-on request but the transmission gear is not in the neutral position, the high-voltage power-on unit 502 controls the transmission controller to send a virtual neutral signal to the vehicle controller.

[0083] The embodiment of the present application determines the handle gear position before the vehicle controller sends the virtual neutral signal, so that the virtual neutral signal is sent to the vehicle controller only when the handle gear position is in the handle neutral position, thereby avoiding the situation that the handle gear position is in a non-neutral position when the vehicle high-voltage power-on is performed, the vehicle moves at idle speed, and a safety accident occurs, and improving the safety during the vehicle power-on process.

[0084] Further, in some embodiments of the present application, the high-voltage power-on unit 502 is also specifically configured to acquire the motor speed of the motor and determine whether the motor speed is less than a threshold speed; when the motor speed is less than the threshold speed and the transmission controller detects a vehicle power-on request but the transmission gear is not in the neutral position, the high-voltage power-on unit 502 controls the transmission controller to send a virtual neutral signal to the vehicle controller.

[0085] The embodiment of the present application determines the motor speed before the vehicle controller sends the virtual neutral signal, so that the virtual neutral signal is sent to the vehicle controller only when the motor speed is less than the threshold speed, thereby avoiding the situation that the motor speed is greater than the threshold speed when the vehicle high-voltage power-on is performed, the vehicle moves uncontrollably, and a safety accident occurs, and further improving the safety during the vehicle power-on process.

[0086] Since the transmission controller that is not in the neutral position needs to be returned to the neutral position after the vehicle is powered on, in some embodiments of the present application, as shown in FIG. 5, the vehicle power-on control device 500 further includes a gear return-to-neutral unit 503, which is specifically configured to:

[0087] control the vehicle controller to send a motor enable instruction to the motor; and based on the motor enable instruction, control the transmission controller to send a motor dither torque instruction to the motor, so that the transmission returns to the neutral position based on the dither torque.

[0088] The embodiment of the present application controls the whole vehicle controller to send a motor enable instruction to the motor by setting the gear return empty unit 503, wakes up the motor, and the motor can provide a jitter torque based on the motor jitter torque instruction sent by the gearbox controller, the jitter torque can make the gearbox gear more easily disengage, complete the return empty operation, and improve the efficiency and success rate of the return empty.

[0089] Further, in the process of the gearbox controller sending a virtual empty signal to the whole vehicle controller to complete the high voltage power-on of the whole vehicle controller, the vehicle enters the intelligent return empty mode, and after the gearbox controller returns the empty gear based on the jitter torque, the vehicle exits the intelligent return empty mode.

[0090] When the mode of the vehicle is the intelligent return empty mode, the gearbox controller is controlled not to respond to the control instruction of the whole vehicle controller.

[0091] The embodiment of the present application controls the gearbox controller not to respond to the control instruction of the whole vehicle controller when the mode of the vehicle is the intelligent return empty mode, which can avoid the gearbox controller responding under the influence of the control instruction, i.e., performing the high voltage power-on action under the condition that the high voltage power-on is not met, resulting in a safety accident, and further improving the safety during the whole vehicle power-on process.
