METHOD OF AND APPARATUS FOR MONITORING THE PERFORMANCE OF A VEHICLE BRAKING SYSTEM

摘要

A method of providing an indication of the performance of the braking system of a vehicle comprising a tractor and a trailer in which, during a braking event, a braking control pressure signal is generated in response to driver demand for braking, the braking control pressure signal indicating a braking control pressure which is representative of the degree of braking required by the driver, and is transmitted to braking systems provided on the tractor and trailer, the method including the steps of determining an average value of the braking control pressure during the braking event, determining an average value of the vehicle deceleration during the braking event, and using both the average braking control pressure and average vehicle deceleration to assign the braking event to one of a plurality of categories.
