  • Speed averaging for variable effort power steering
    Patent number: 5381336
    Abstract: A variable effort power steering unit under control of a microcomputer is able to change steering effort in response to control current. The 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.

  • Multimode radar for road vehicle blind-zone target discrimination
    Patent number: 5325097
    Abstract: A road vehicle radar system for discriminating between hazard and non-hazard targets within a predetermined zone uses a pair of frequency modulated continuous wave radar cycles (FM-CW) and a single continuous wave cycle (CW) in the generation of radar quantities for measuring target range and apparent target velocity. Measured quantities from the FM-CW and CW cycles are compared with predetermined quantities for discriminating between hazard and non-hazard targets.
