Wheel load-based type intelligent sensing wheel brake performance monitoring methods

Abstract

The invention discloses a wheel braking performance monitoring method based on wheel-load type intelligent sensing. Intelligent sensing modules are arranged on hub equatorial planes of wheels of a motor vehicle, and an intelligent sensing unit is arranged on a vehicle body; and after conditioning and the calculation of digitization, gesture algorithm and braking algorithm are carried out for a sensing signal, main braking performance parameters of the wheels can be obtained. The main braking performance parameters of the wheels monitored by the system comprise wheel slip rate, road surface attachment coefficient of the wheels, wheel braking force, wheel braking deceleration, and the like. By means of carrying out multi-sensing-data fusion and analysis on the parameters, the method can monitor and initiatively evaluate the movement safety condition of the motor vehicle, thereby being beneficial to avoiding and reducing traffic accidents.

Problems solved by technology

[0004] At present, the monitoring of wheel braking performance is mainly through the monitoring of a single index of wheel braking deceleration, and it has not yet been able to effectively monitor parameters such as wheel slip rate, wheel road adhesion coefficient, and wheel braking force, so that it cannot be fully evaluated. and predict the braking performance of motor vehicles (including the braking performance of anti-lock brake ABS of motor vehicles); the detection and evaluation of the braking performance of motor vehicles mainly relies on regular safety inspections, and the real-time monitoring of the braking performance of motor vehicles has not been carried out; at the same time , the monitoring of the deceleration parameters of the wheel brakes only uses the wheel speed sensor to measure the wheel speed directly, and has not yet evaluated the parameters measured by the wheel speed sensor
