Abstract
A system and method for generating a signal which indicates whether a motor vehicle containing such a system is operating on a rough road surface. The generated signal is based on the signals output by a sensor that measures the air-mass flow rate through the air-intake manifold of an internal-combustion engine. The system and method use the differences in the signals output by the sensor when on a smooth road surface and a rough road surface to generate the signal indicative of a rough road surface. The rough road indication signal can be applied, inter alia, to engine misfire detection, anti-lock braking control, and vehicle chassis regulation.
