When the device is not in use, supply of power to a computer CPU for controlling the device is automatically interrupted, thus prolonging the service life of the CPU and eliminating useless power consumption. The need of manual operation of a power-on switch can be dispensed with. When at least one of a set switch and a resume switch is actuated, supply of power to the CPU is automatically turned ON using a flip-flop circuit. If the vehicle speed is memorized during an ON state, the CPU is still held in an ON state. But if the vehicle speed is cleared, the CPU controls the flip-flop to set OFF supply of power. In case the vehicle speed is less than a given value, the memorized vehicle speed is cleared irrespective of the state of the set switch and the resume switch.

A parking assisting apparatus is provided in which even a beginner can relaxedly park a vehicle and parking operation is pertinently assisted. The apparatus provides a cameras 1 for taking an image rearwardly of a vehicle during parking the vehicle. The image from the camera is displayed on a display 13 provided inside the vehicle as a rear image and a running prediction locus 20 is displayed which varies in accordance with the state of a steering wheel angle to overlap the rear image. A longitudinal line parking switch 4b instructs the vehicle to park along a longitudinal line and when the longitudinal line parking is instructed there is displayed a running prediction locus 20a having a point of inflection in accordance with the steering wheel angle.
摘要:

It is suitable for use in minute processing.
摘要:
A vehicle speed control system comprising an automatic speed control system for controlling the vehicle velocity to a set velocity selected by an operator, and automatic transmission control system for controlling the speed stage of the automatic transmission of the vehicle in response to the deviation between the actual vehicle velocity and the set vehicle velocity of the automatic speed control means. The automatic transmission control system comprises two operating modes including a first mode when the automatic speed control system is controlling the vehicle velocity, and a second mode when the automatic speed control system is not controlling the vehicle velocity, and the automatic transmission control system prohibits the shift of the speed stage to a fixed speed stage when the automatic speed control system is controlling the vehicle velocity. The automatic speed control system does not detect a shift of the speed stage when the automatic speed control system is controlling the throttle valve during shifting of the speed stage. The automatic speed control system controls a throttle valve in response to an abnormal state of the transmission.

An automobile speed control system has a comparator circuit for issuing a speed difference signal when there is a difference between an automobile speed signal indicative of an automobile speed and an automobile speed setting signal indicative of a desired speed setting, an actuator responsive to the speed difference signal for adjusting the opening of a throttle valve to change the speed of an automobile in order to eliminate the speed difference signal, a cancel switch for cancelling a constant-speed travel mode of the automobile, a resume switch for resuming the constant-speed travel mode which has been cancelled, a timer circuit energizable for a prescribed interval of time in response to operation of the resume switch while the automobile is running in the constant-speed travel mode, and an acceleration signal generator circuit for generating an acceleration signal in response to operation of the resume switch while the timer circuit is in operation, whereby the acceleration signal can be produced to increase the speed of the automobile when the resume switch is actuated.
