Abstract:
1. A control system for a motor vehicle having an engine comprising: an engine control unit for controlling the engine; a driver accelerator control; a driver braking control; said driver accelerator control and said driver braking control providing to the engine control unit, respectively, a driver demand signal and a braking demand signal that indicate, respectively, a level of driver engine demand and a level of driver braking demand, the engine control unit being arranged to: a) calculate a first delay following the time at which the driver demand signal indicates a level of driver engine demand above a first predetermined level of driver engine demand; b) calculate a second delay following the time at which the braking demand signal indicates a level of driver braking demand above a first predetermined level of driver braking demand; c) determine a predetermined delay, the predetermined delay being the later of the first delay and the second delay; and d) over-ride the driver demand signal to reduce engine power when, after the predetermined delay, both the driver demand signal and the braking demand signal are above the predetermined levels of driver engine demand and driver braking demand.
