Abstract

A method of operating an auto-braking system of a vehicle in coordination with operation of a speed limiting system (SLS) of the vehicle to prevent undesired loss of auto-braking functionality. If: a) a driver input of an engine power control parameter (such as throttle setting) exceeds an activation threshold of the SLS so that the SLS is therefore limiting vehicle speed to a set-speed corresponding to the activation threshold; and b) the driver input of the power control parameter is below a SLS override threshold; and c) the SLS override threshold exceeds an auto-braking override threshold for the power control parameter; then the auto-braking override threshold is increased to at least equal the SLS override threshold. The speed limiter activation threshold may be determined from speed limit information supplied by a vehicle navigation system of by an image evaluating unit from images obtained by a camera of the vehicle.
