Abstract
The present disclosure provides a method of controlling an automatic engine stop of an automotive system, during a coasting phase. A dynamic speed threshold is calculated as a minimum value of a plurality of dynamic speed values. Each dynamic speed value is calculated as a function of an automotive system parameter such as a steering wheel angle, a steering wheel angle rate, a wheel speed difference, an antilock braking system status, or an electronic stability control status (p) and/or a road condition such as road grade. The automatic engine stop is enabled when a vehicle speed is lower than the dynamic speed threshold.
