Beschreibung
Zusammenfassung:	A vehicle speed control system includes an engine control system 36 with an engine idle speed controller 37 which maintains the engine idle speed set point I for varying engine torque outputs, and a vehicle braking system 13,14,20, for braking the vehicle and which is operated by a deceleration demand means 22,32. The idle speed controller 37 is arranged to receive signals from the deceleration demand means 22,32 and any increase in engine torque output demanded by the idle speed controller 37 to maintain idle speed is limited in response to signals received from the deceleration demand means 22,32.
