ABSTRACT:
A new automotive (speed control system) safety feature is disclosed. A vehicle with an engaged speed control could be dangerous to drive on a road surface that changes from dry, offering little rolling resistance, to a surface that offers increased resistance to tire rotation. Resistance to tire rotation by water or snow on a road surface will cause an engaged speed control system to try and maintain the set vehicle speed by accelerating the vehicle into the rolling resistance. A driver may lose control of the vehicle in this circumstance if the speed control cannot be disabled immediately. The new safety feature disclosed would automatically disable the vehicle speed control system when the vehicle decelerates due to significant water or snow accumulation on the road surface.
