摘要:
A vehicle obstruction detection system (15) for discriminating between hazardous and non-hazardous obstructions (13) within a predetermined zone uses a pair of frequency modulated continuous wave radar cycles (FM-CW) and a single continuous wave radar cycle (CW) in the generation of radar quantities for measuring obstruction range and apparent obstruction velocity. Measured quantities from the FM-CW and CW cycles are compared with predetermined quantities for discriminating between hazardous and non-hazardous obstructions (13).

摘要:
A variable effort power steering unit (10) under control of a microcomputer (16) is able to change steering effort in response to control current. The control current is developed as a function of average vehicle speed. In the case of vehicle deceleration, a long averaging time is used to inhibit rapid steering effort changes during braking. In the case of vehicle acceleration, a short averaging time is used for rapid response of steering effort to speed increases.
