| Abstract: | According to the disadvantages of the braking force of man-machine is intercoupling and the pipeline arrangement of the brake hydraulic pressure adjustment unit is complicated in the traditional braking system.It presents an integrated novel wire-by-wire hydraulic braking system,and designs and matches a hydraulic adjustment unit that complies with the braking system.Based on this,two kinds of braking anti-lock control strategies are proposed:dual power source time-sharing constant frequency control and type II four-channel time-sharing control.By establishing the braking system and the vehicle dynamics model,simulation analysis is performed for two typical working conditions.The results show that the two proposed anti-lock control strategies can meet the functional requirements of anti-lock braking. |
