Patent number: 5502365Abstract: A driving control apparatus consists of a battery for storing electric energy supplied to a motor-driven compressor and a drive motor, a direct current detector for detecting a direct current supplied from the battery to the compressor, a direct current voltage detector for detecting a d.c. voltage applied by the battery, a controller for calculating an electric power consumed by the motor-driven compressor, determining an upper limit of the electric power in dependence on the d.c. voltage, judging whether or not the electric power is larger than the upper limit, and controlling the compressor to reduce the electric power in cases where the electric power is larger than the upper limit. Because the upper limit of the electric power is determined in dependence on the d.c. voltage and because the electric power becomes necessarily lower than the upper limit, an electric tar is not stalled by the exhaustion of the electric power in the battery before a driver arrives at his destination.Type: GrantFiled: August 30, 1993Date of Patent: March 26, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yasuo Nanbu, Makoto Yoshida
