A method and system of limiting speed of a light-weight utility vehicle such as electric golf cars or maintenance vehicles of golf courses and parks. The method includes receiving a terrain roughness signal generated from a motion sensor. The signal indicates a roughness of a terrain over which the utility vehicle is traversing. The method additionally includes determining a peak-to-peak amplitude of the terrain roughness signal and limiting the speed of the utility vehicle if the peak-to-peak amplitude is greater than a maximum threshold. Preferably the sensor is mounted to a suspension member. The vehicle speed may be controlled based on an accelerator position or by controlling the brake pressure. |
