Vehicle dynamics control system with varying sensor configurations
First Claim
1. A vehicle dynamics control system for controlling movement of a vehicle having wheels and brakes at said wheels, said system comprising:
- selectable sensor means for producing sensor signals including a steering angle signal, and at least one signal selected from the group consisting of a first lateral acceleration signal, a second lateral acceleration signal, and a yaw velocity signal,controller means comprising a first controller area connected with the sensor means, said first controller area forming a plurality of controller internal variables as a function of said sensor signals dependent on which of said group of signals are produced by said sensor means, and a second controller area forming control signals as a function of said plurality of controller internal variables, said function being independent of which of said group of signals are produced by the sensor means, andmeans for applying a brake force at the wheels as a function of at least the control signals.

Abstract
A movement variable which represents the movement of a vehicle is controlled by actuating at least one actuator for applying a braking force to the wheels. Controller means use controller internal variables to form signals for influencing the actuators with the effect of adjusting a control variable. The controller means has a first area adapted to the respective selected sensor configuration in such a way that the controller-internal variables are formed on the basis of the sensor signals, and a second area for processing the controller-internal variables independently of the selection of the sensor configuration. As a result, simple adaptation with low development and application outlay to a wide variety of sensor configurations is possible.
