Abstract:
An integrated stability control system using the signals from an integrated sensing system for an automotive vehicle includes a plurality of sensors sensing the dynamic conditions of the vehicle. The sensors include an IMU sensor cluster, a steering angle sensor, wheel speed sensors, any other sensors required by subsystem controls. The signals used in the integrated stability controls include the sensor signals; the roll and pitch attitudes of the vehicle body with respect to the average road surface; the road surface mu estimation; the desired sideslip angle and desired yaw rate from a four-wheel reference vehicle model; the actual vehicle body sideslip angle projected on the moving road plane; and the global attitudes. The demand yaw moment used to counteract the undesired vehicle lateral motions (under-steer or over-steer or excessive side sliding motion) are computed from the above-mentioned variables. The braking control is a slip control whose target slip ratios at selective wheels or wheel are directly generated from the request brake pressures computed from the demand yaw moment.
