Research on Anti-Lock Braking Control Based on Vehicle Operation Parameters Adaptive Soft-Sensing Algorithm
A soft-sensing algorithm which combines Sage-Husa noise estimator and unscented kalman filter(ukf)is established.Vehicle operating parameters such as vehicle speed are effectively measured by adaptive soft sensing algorithm.Actual slip rate of vehicle anti-lock braking system is calculated in real time by combining with easily measured wheel speed signal obtained by wheel speed sensor,so as to realize effective control of wheel cylinder pressure and avoid wheel lock.Through CarSim/Simulink co-simulation experiment,it is shown that adaptive soft sensing algorithm can realize accurate measurement of vehicle speed,and can effectively inhibit wheel locking in the braking process on the split road,so as to ensure vehicle braking stability.
