Abstract
The utility model relates to an automobile anti-lock control device which comprises a control device body, a braking device and four sets of speed sensing devices. The four sets of speed sensing devices are arranged on four tires of an automobile respectively. Each speed sensing device comprises a pressure control valve and a speed sensor. Each speed sensor is installed at the position of each tire of the automobile and connected with each pressure control valve through a transmission rod. The pressure control valves are connected with the control device body through transmission rods and transmit speed signals of the tires to the control device body. A delayer is arranged between the control device body and the braking device. The control device body receives the speed signals of the tires and sends a braking command to the delayer after the speed signals are analyzed. The delayer sends the braking command to the braking device after the braking command is delayed. The braking device conducts braking on the tires according to the braking command. The automobile anti-lock control device reduces the additional yawing moment generated by the automobile, enables the automobile to be easily controlled and enables the automobile to be free of side slipping so as to reduce potential safety hazards.
