Abstract
An antilock control device for the brake assembly of a motor vehicle having the function of detecting ON and OFF signals supplied from a brake lamp switch and representative of the operative and inoperative positions of the brake pedal. When the signal changes from OFF to ON, which means that the brake pedal has been trodden, the antilock control function is disabled so that the pressure generated in the master cylinder will be directly applied to the wheel cylinders. This state continues until the antilock device detects a locking tendency of any wheel. In addition to the brake lamp switch signals, signals representative of the ON and OFF positions of the accelerator pedal may be supplied to the antilock control device so that the antilock control function will be disabled when either the accelerator pedal position signal changes from OFF to ON or the brake pedal position signal changes from ON to OFF.
