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 connection.

[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 seco...

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-slip control method which is applied to an anti-slip control system. The system comprises a vehicle body electronic stabilization system and an active anti-slip controlsystem, and the method comprises the following steps: acquiring state information of the vehicle body electronic stabilization system; comparing the state information of the vehicle body electronic stabilization system with first preset condition and second preset condition information; when the first preset condition is met, using an active anti-slip control system for carrying out anti-slip control; and when the second preset condition is met, using the vehicle body electronic stabilization system for anti-slip control. The anti-slip control method of the active anti-slip control system comprises the steps of: obtaining the slip vehicle speed difference; comparing the slip vehicle speed difference with a preset value; and when the preset value is not met, adjusting the actual torque according to the slip vehicle speed difference. The ESP is not affected, the active anti-slip control system is added, and driving is safer. The active anti-slip control system directly calculates the torque and distributes the torque, and the response is faster. Mode compensation is added, so that slipping speed calculation is more accurate. The invention discloses an anti-slip 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...
