Abstract
A monitoring system to control lift axles on a vehicle having a means for sensing vehicle speed and direction, a means for measuring the weight on the lift axles and fixed axles on the vehicle, and a control module for controlling one or more lift axles on the vehicle is provided. The control module comprises a receiver for receiving information from the sensing means and the measuring means, a processor, and output means for causing the lift axles to be lifted when the vehicle is moving in reverse. The processor causes or permits the lift axle to 1) lower when the vehicle moves forward for a programmable distance, 2) assume or maintain a lifted position when the vehicle is below a predetermined weight, 3) assume or maintain a lowered position when the vehicle carries over a predetermined weight, and 4) equalize weight between the lift axles and the fixed axles.
