METHOD OF MONITORING A VEHICLE AND APPARATUS THEREFOR

摘要

A method of monitoring a vehicle 10 using a sensor to measure a parameter which depends on the forces acting on the vehicle 10 generally normal to the surface over which the vehicle is travelling, transmitting a force signal from the sensor to a processing apparatus 16 (the main braking electronic control unit), the processing apparatus 16 processing a plurality of said force signals to determine a value indicative of the forces acting on the vehicle generally normal to the surface over which the vehicle is travelling over a specific period of time. The processor 16 is provided with a pressure transducer to provide an electrical signal indicative of the air pressure in line 23, and hence the pressure in air springs 22. Alternatively, each of the air springs 22 is provided with a pressure sensor to sense the air pressure in the spring 22, and the processor is provided with an input to receive an electrical pressure signal from the pressure sensor.
