Abstract
This paper proposes the use of an ultrasonic sensor module which is used to calculate the ground clearance of a heavy motor vehicle (HMV). The sensor calculates distance based on the estimation of the travelling time of an ultrasonic pulse, transmitted by an ultrasonic sensor, which gets reflected back from the ground. These low-cost sensors seem ideal to be housed underneath HMVs running in hilly areas with narrow roads, which have the risk of falling off the cliffs in sharp turns. The sensors will be placed such that whenever the vehicle’s rear wheel senses a height more than that of the wheel by a considerable amount, the vehicle will move away from the cliff and the automatic braking system will be activated. The system may be used similarly in dumper HMVs that need to fill large shallow holes with mud, sand, etc.; the sensor will be placed differently in such condition.
