The invention discloses a four-wheel distance measurement device. The four-wheel distance measurement device comprises six ultrasonic distance measurement modules, an operational amplifier, an A/D converter and a controller. The ultrasonic distance measurement modules are arranged at the two ends and the middle of a vehicle front side protection bar and the two ends and the middle of a vehicle back side protection bar respectively and are used for outputting distance measurement signals. The operational amplifier is used for performing power amplification on the distance measurement signals. The A/D converter converts the distance measurement signals into digital signals from analogue signals. The input end of the controller receives the distance measurement signals in a digital format, simulates obstacles around a vehicle according to the distance measurement signals, displays the distance between simulated obstacles and the distance between the vehicle and obstacles on a liquid crystal display, and gives out an alarm sound when the measured distance is smaller than an alarm value.
