Embodiment 1

[0079] Such as Figure 1-3 Shown is an anti-skid control method based on two systems of the electronic stability system (ESP) and the active anti-skid control system.

[0080] The anti-skid control method is applied to an anti-skid control system. The anti-skid control system includes a vehicle body electronic stability system, an active anti-skid control system, and a vehicle controller. System electrical connections.

[0081] Skid control methods include:

[0082] S110: The vehicle controller obtains the state information of the electronic stability system of the vehicle body;

[0083] S120: Comparing the state information of the vehicle body electronic stability system with the information of the first preset condition and the second preset condition.

[0084] When the vehicle body electronic stability system satisfies the first preset condition, execute step S200 to perform anti-skid control by using the active anti-skid control system. If the vehicle satisfies the sec...

Embodiment 2

[0142] An anti-skid control system includes a vehicle body electronic stability system, an active anti-skid control system and a vehicle controller, and the vehicle controller is electrically connected to the vehicle body electronic stability system and the active anti-skid control system respectively.

[0143] The vehicle controller includes:

[0144] A status information acquisition module, configured to acquire status information of the vehicle body electronic stability system;

[0145] State information comparison module: used to compare the state information of the vehicle body electronic stability system with the information of the first preset condition and the second preset condition.

[0146] The first control module: used for performing anti-skid control by using the active anti-skid control system when the body electronic stability system meets the first preset condition.

[0147] The second control module: used for performing anti-skid control on the vehicle body ...

Abstract

The invention discloses an anti-skid control method, which is applied to an anti-skid control system. The system includes an electronic stability system of a vehicle body and an active anti-skid control system. The method includes: acquiring state information of the electronic stability system of a vehicle body; Information comparison between the first preset condition and the second preset condition; when the first preset condition is met, the active anti-skid control system is used for anti-skid control; when the second preset condition is met, the body electronic stability system is used for anti-skid control; active anti-skid The anti-slip control of the control system includes: acquiring the slipping vehicle speed difference; comparing the slipping vehicle speed difference with a preset value; and adjusting the actual torque according to the slipping vehicle speed difference when the preset value is not satisfied. The invention does not affect ESP, adds an active anti-skid control system, and drives safer. The active anti-skid control system directly calculates and distributes torque for faster response. By adding mode compensation, the skidding speed calculation is more accurate. The invention discloses an antiskid control system.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an anti-skid control method and system. Background technique [0002] Hybrid vehicles, that is, the power of the vehicle comes from multiple systems, and the common one is gasoline-electric hybrid, which means that the power of the vehicle is a gasoline internal combustion engine and an electric motor, which consume gasoline and electricity respectively. Traditional four-wheel drive hybrid vehicles, on the one hand, due to the structure of the central differential, will lead to problems such as complex structure and high cost; on the other hand, they cannot intelligently distribute the torque of the front and rear axles, which will affect the driving stability of the vehicle. [0003] Electronic Stability System (ESP) is a general term for a system or program that aims to improve the handling performance of the vehicle and effectively prevent the vehicle from losing co...
