Abstract:
A pump operation control apparatus for a hydraulic brake boosting system wherein hydraulic pressure in an accumulator accumulated by a pump is allowed to boost the operation of a brake operating member to generate braking force, said apparatus comprising:a timer for measuring time elapsed from operation of a brake in accordance with an operation signal generated by a brake operating member to transmit an output signal when measured time has reached predetermined time; anda pump-operation-signal generating means for transmitting an operation signal of the pump in response to the operation signal generated by the brake operating member and transmitting an interruption signal of the pump in response to the output signal from said timer;wherein the operation of the pump is controlled such that the operation of the pump is started in response to the operation signal generated by the brake operating member and that the operation of the pump is interrupted after the predetermined time has elapsed from the operation of the brake operating member.
