えて成る車両間隔保持装置。 A transmitting circuit that emits an electrical signal at a constant transmission frequency, a wave transmitter that converts the electrical signal into a wave and sends it to the preceding vehicle, and a wave transmitter that receives the reflected wave from the preceding vehicle and converts it into an electrical signal. A receiver for converting, a receiving circuit that emits an output signal according to the difference between the receiving frequency of the receiver and the transmitting frequency, and a receiving circuit that receives the output signal and transmits the received frequency to the speed control device of the vehicle. A vehicle distance maintaining device comprising an acceleration/deceleration control circuit that outputs a deceleration command when the receiving frequency is higher than the transmitting frequency, and outputs a speed increasing command when the receiving frequency is lower than the transmitting frequency.
