Example Embodiment
[0035] Example one
[0036] This embodiment provides an anti-slipping control method for a hybrid electric vehicle. When the sliding speed is low, the driving motor is separately controlled to stabilize the vehicle. When the sliding speed is high, the engine and the driving motor are used to maintain the stability of the vehicle together, which can be fast Effectively maintain the stability of the vehicle, with strong reliability, and in the process of controlling the slope, the torque of the drive motor is intermittently reduced to prevent the drive motor from becoming severely heated due to a long blocking time, and to ensure the life of the drive motor and the entire vehicle.
[0037] Such as figure 1 As shown, the anti-slipping control method of the hybrid electric vehicle includes the following steps:
[0038] S1. Obtain the vehicle signal;
[0039] After the vehicle is powered on, the vehicle signal is obtained in real time. Optionally, the vehicle signal includes a gear signal...

[0059] Example two
[0060] figure 2 This is a schematic diagram of the structure of the hybrid vehicle in this embodiment. figure 2 A block diagram of an exemplary hybrid vehicle 412 suitable for implementing embodiments of the present invention is shown. figure 2 The hybrid vehicle 412 shown is only an example, and should not bring any limitation to the function and scope of use of the embodiment of the present invention.
[0061] Such as figure 2 As shown, the hybrid vehicle 412 is represented in the form of a universal terminal. The components of the hybrid vehicle 412 may include, but are not limited to: a hybrid vehicle body (not shown in the figure), one or more processors 416, a storage device 428, connecting different system components (including the storage device 428 and the processor 416) 的BUS 418.
[0062] The bus 418 represents one or more of several types of bus structures, including a storage device bus or a storage device controller, a peripheral bus, a graph...

[0079] Example three
[0080] This embodiment provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, the method for anti-slipping control of a hybrid electric vehicle as provided in the embodiment of the present invention is implemented, and the method includes:
[0081] S1. Obtain the vehicle signal;
[0082] S2, based on the vehicle signal, determine whether the current vehicle state meets the conditions of anti-slipping, if yes, skip to S3, if not, end;
[0083] S3. If the driving motor speed is greater than the first threshold, start the engine and jump to S4, where the first threshold can be calibrated; if the driving motor speed is not greater than the first threshold, the engine maintains the stopped state and jumps to S4;
[0084] S4. Enable the PI calculator and adopt the closed-loop proportional integral PI control method. From the drive motor speed, the proportional term and integral term coefficients ar...
