ABSTRACT:
The present invention is directed to a method and apparatus for estimating incline and bank angles of a road surface upon which a front wheel drive vehicle is travelling. Each nondriven rear wheel is equipped with a rotational speed sensor. The vehicle is further equipped with longitudinal and lateral accelerometers mounted to the vehicle chassis above the centerline of the rear axle. Outputs from the speed sensors and accelerometers are fed into a vehicle on-board controller and utilized in computing the incline and bank angles of the road surface. Updated incline and bank angles are maintained in the controller's memory for access by various control systems to alter vehicle attributes for improved handling and operation.
