Abstract
A system for preventing a vehicle from running away downhill and for ensuring a smooth take-up from rest, in which signals proportional to engine speed (Ve) and vehicle speed (Vdp) are used. The engine speed signal is compared with a reference signal (Vs) to produce an engagement signal (E) which controls a clutch actuation means for engagement of the clutch. The vehicle speed signal (Vdp) and the engine speed signal (Ve) are fed into a filter (71) which produces a clutch actuation signal if either (Vdp or E) exceeds a predetermined value.
Claims10
A friction clutch control system for a vehicle having a clutch, a gearbox and an engine, the system comprising a vehicle speed sensor for generating a vehicle speed signal variable with the speed of the vehicle, a clutch engagement signal generator that produces an engagement signal utilised for controlling a clutch actuation means that operates the clutch engagement, a filter means that receives the engagement signal and the vehicle speed signal to generate a clutch actuation signal for operation of the clutch actuation means for engagement of the clutch in the event that either the vehicle speed signal and/or the engagement signal exceeds a predetermined minimum value.
