Abstract
A dynamometer, which includes a frictional drive assembly for engaging a pair of vehicle tires, and a lift assembly including two air bags for respectively lifting the vehicle tires and the associated portion of the vehicle to a raised position out of engagement with the drive assembly, has a controller operating under stored program control and pressure sensors connected to the controller and in fluid communication with the air bags. The pressures in the air bags when the vehicle is lifted are used to calculate the weight lifted in accordance with a straight-line functional relationship between air bag pressure and vehicle weight lifted for a particular type of air bag. A routine for calibrating the weighing system is also included.
