The invention applies a single-chip microcomputer technology to transmit a relative distance between a vehicle and a front vehicle and the speed of the vehicle relative to the front vehicle, collected by a radar distance and speed measuring sensor, to a single-chip microcomputer. Through a program in the single-chip microcomputer, each relative vehicle speed has the corresponding alarm vehicle distance and braking vehicle distance; and the alarm vehicle distance and the braking vehicle distance are corrected by using the vehicle speed. When the relative vehicle distance is shorter than the alarm vehicle distance, the single-chip microcomputer controls an in-vehicle buzzer to give an alarm to drivers, and prompts the drivers to decelerate or to stop the acceleration; and when the relative vehicle distance is shorter than the braking vehicle distance, the single-chip microcomputer controls a stepper motor to brake a braking pedal. Radar monitors the relative vehicle distance and the relative vehicle speed all the time, and continuously provides the input information to the single-chip microcomputer. When the vehicle distance is returned to a safety range, the single-chip microcomputer stops the braking operation and the alarm. The set of intelligent electronic measuring and control device guarantees that front and back vehicles always keep in the safe vehicle distance range, so that the road rear-end collision is effectively prevented, and the vehicle safety is further improved.
