    • A constant-speed running device for automobiles maintaining high safety in which an OFF signal of a very short period of time that does not affect the operation of an actuator (2) is periodically provided by control signal OFF means (6) for a signal that is produced by a microcomputer (7) to control the actuator (2), and the presence or absence of the OFF signal is monitored by control signal monitoring means (10). When no OFF signal is detected for more than a predetermined period of time, it is so determined that the microcomputer malfunctions and the actuator (2) is driven toward a direction to close the throttle valve (1) via throttle closure control signal output means (11). In case the microcomputer malfunctions, therefore, the throttle valve (1) is closed and the running is reliably resumed based on the acceleration pedal operation by the driver.

    • A device for driving a brushless motor comprising drive coils (1) to (3), drive transistors (10) to (15), a voltage controlled oscillator (40), a current switching circuit (44), a phase error detector (20) having a comparator (27), and an error amplifier (30). The output of the error amplifier (30) is input to the voltage controlled oscillator (40), whereby no filter is required that was so far used, and the number of capacitors of large capacities can be greatly reduced. It is further made possible to prevent spike noises included in the current waveforms supplied to the drive coils, voltage drop due to the current that flows and the impedance of drive coils, variance in the power source voltage and the load, and the drop of efficiency due to the armature reaction.
