Abstract

The invention relates to controlling system of machine anti-lock brake system including signal collection unit and electron controlling unit comprising date incepting unit, date processing unit and date controlling unit. The mentioned date receiving unit is designed for gathering date of signal gathering unit and the mentioned date processing unit is designed for calculating the listing angle and the gliding ratio, the date controlling unit enacts the threshold value by the corresponding gliding ratio of the peak value of brake power coefficient u when it has the varying side leaning angle, then we can carry ABS controlling via the controlling dictates by comparing the calculated sliding ratio and the enacted the threshold value of sliding ratio. If we adopt the system and means provided by the invention, when machine wheels, every wheel has side leaning angle, if driver applies the brake, so it is assured that the car avoids the deflection and has the shortest braking distance. So it improves the security of the machine. The system is applied for machine running in a beeline.

Description

technical field [0001] The invention relates to a control system and a control method of an anti-lock brake (ABS) of a motor vehicle, and belongs to the field of ABS control of a motor vehicle. Background technique [0002] In the existing motor vehicle control system, it is possible to control the motor vehicle more effectively by obtaining some parameters at the moment of driving of the motor vehicle, such as parameters such as the side slip angle and the slip rate of the motor vehicle. The measurement of the driving parameters of the early motor vehicles was based on various on-board sensors. With the widespread use of GPS, the technology of using GPS technology to calibrate the sensors to obtain the driving parameters of the motor vehicle has been widely proposed. [0003] USP 6681180 provides a method for judging whether the wheels of a motor vehicle are slipping or slipping through GPS based on a two-wheeled motor vehicle model. By using this method, the side slip angl...
