ABSTRACT:
The present invention relates to a motor vehicle having a brake mechanism capable of braking the vehicle to a stop, detection means adapted to detect the presence of a foreign object in the direct path only of slow movement of said vehicle on a supporting surface, and control means to apply the brakes and stop movement of said vehicle instantly upon the detection of such an object. The detection means, which preferably is yieldable a sufficient distance upon contact with a foreign object to prevent damage thereto while said vehicle is braked to a stop, may comprise a straight front part as wide as the vehicle with end panels extending at right angles to and away from the straight part, a like rear part, and/or an L-shaped flap on one or both sides of the vehicle having two integral panels with one of them at the front of the rear tires on one or both sides of said vehicle and the other extending along and spaced from the tire. A school bus is a vehicle to which the invention may very advantageously be applied at the front, the rear, and near the right rear tire or near both rear tires. The flap preferably has a rigid upper portion and a flexible lower portion which enables the lower flexible portion to yield if it comes into contact with the supporting surface for the vehicle when it is sufficiently rough and irregular to bring the lower edge into contact with it. The invention includes means for inactivating the control means when the speed of movement of the vehicle exceeds about seven miles per hour or when a predetermined short time interval, e.g., 12 to 15 seconds, has expired.
