Control method and device for the propulsion motor unit of a motor vehicle driven by an internal combustion engine

摘要

A control for a vehicle including a controller for a propulsion motor unit, which generates a signal representative of the depression of an accelerator pedal operated by the vehicle driver and detects a degradation of the signal. On detection of such a degradation the speed of the vehicle is regulated if above a threshold value and the operating speed of the engine is regulated if the vehicle speed is below the threshold value.
