Distance regulation system for vehicles following close behind each other on road has computer emitting reference signal for comparison with actual distance signal

摘要

The distance regulating circuit (10) has a selection switch (12) passing acceleration or retardation signals (plus or minus a) to a computer (13). This computer receives a speed signal (Ve) an produces a reference or desired distance signal (Ssoll). A regulating circuit (14) compares this signal with an actual distance value (Sist). The output is a desired acceleration signal (awu), which is fed to a calculator (15), producing motor and brake control signals (Imot,Ibrems).
