Vehicle speed regulation system - uses limitation of actual speed signal and adjustment of regulator characteristics, dependent on engine operating parameters

The speed regulation system compares signals (VS,VIM) representing the actual and desired speeds. The obtained difference is supplied to a proportional regulator (195) for controlling a throttle setting device. The actual velocity signal (V,I) is limited and/or the regulation transfer characteristic...

Zusammenfassung:The speed regulation system compares signals (VS,VIM) representing the actual and desired speeds. The obtained difference is supplied to a proportional regulator (195) for controlling a throttle setting device. The actual velocity signal (V,I) is limited and/or the regulation transfer characteristics are controlled in dependence on the engine operating parameters. Pref. the variation in the actual velocity signal is limited to a max. range the latter set to zero when the sign of the measured velocity and the sign of the variation in the rev signal do not agree. ADVANTAGE - Accurate regulation of vehicle velocity with regulation dynamics dependant on selected gear and engine revs.
