Abstract

The invention relates to a racing car stability control device and control method. According to the racing car stability control device and control method, due to the fact that the structure that a mass center sensor, a wheel speed sensor, an angle sensor, a pressure sensor and an angular velocity sensor send collected signals to a vehicle control unit ECU, the vehicle control unit ECU transmits signals to an ABS and a balance control device according to a specific control method, the ABS carries out brake on a single wheel or multiple wheels, and the balance control device carries out corresponding balance control is adopted, a racing car can detect the running gesture of the racing car when the racing car is driven at a curve in real time, the stability of the racing car under extreme steering, braking, driving and complex working conditions is guaranteed, and the stability problem of the racing car when large lateral acceleration and large side slip angles exist can be solved. In addition, according to the racing car stability control device and control method, an existing anti-lock braking system and an existing traction control system can be utilized for generating needed longitudinal force, the original structure of the racing car is not changed greatly, and the racing car stability control device and control method are good in stability control effect and easy to popularize and apply.

Description

technical field [0001] The invention relates to a racing car stability control device and a control method, which belong to the transformation technology of the racing car stability control device and the control method. Background technique [0002] For passenger cars, driving safety has become a common concern of the whole society, while racing cars have stricter requirements for driving safety. When a danger is about to occur, the driver can manipulate the steering wheel to evade, or perform emergency braking to avoid traffic accidents. The side slip angle of the center of mass is usually large, and the effect of the driver controlling the wheels through the steering wheel is not obvious, and ordinary drivers will also be unable to take the correct operation method or even make a wrong operation because of panic, and the racing car will skid, turn sharply or fail due to Dangerous driving situations due to loss of stability such as sluggish steering response.
