Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
157 words
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, and means for applying a brake force at the wheels as a function of at least the control signals.
Claim 2
Dependent Claim
157 words
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, and means for applying a brake force at the wheels as a function of at least the control signals.
Claim 3
Dependent Claim
24 words
A vehicle dynamics control system as in claim 1 wherein said selectable sensor means comprises a steering angle sensor and a yaw speed sensor.
Claim 4
Dependent Claim
19 words
A vehicle dynamics control system as in claim 1 wherein said selectable sensor means comprises a steering angle sensor.
Claim 5
Dependent Claim
28 words
A vehicle dynamics control system as in claim 1 wherein said selectable sensor means comprises a steering angle sensor, a yaw speed sensor, and a lateral acceleration sensor.
Claim 6
Dependent Claim
32 words
A vehicle dynamics control system as in claim 1 wherein said selectable sensor means comprises a steering angle sensor and a pair of lateral acceleration sensors at different points on the vehicle.
Claim 7
Dependent Claim
49 words
A vehicle dynamics control system as in claim 1 wherein said first controller area forms one of said controller internal variables so as to represent one of lateral movement and yawing movement of the vehicle, independently of which of the group of signals are produced by the sensor means.
Claim 8
Dependent Claim
91 words
A vehicle dynamics control system as in claim 1 wherein said controller means comprises: a first submodule which forms a desired range of one of the control variables, said range being defined by a minimum control variable and a maximum control variable each formed as a function of at least one of said first lateral acceleration and said yaw velocity and a second submodule which forms said one of the controller internal variables, compares it with the desired range of control variables, and forms said control signals based on said comparison.
Claim 9
Dependent Claim
89 words
A vehicle dynamics control system as in claim 7 further comprising means for detecting rotational movement of the wheels, said controller means further comprising: a third submodule which forms one of the controller internal variables such that said controller variable represents a current travel situation of the vehicle, as a function of the rotational movements of the wheels and at least one of said lateral acceleration and said yaw velocity, and feeds said one of said controller internal variables to at least one of said first and second submodules.
Claim 10
Dependent Claim
28 words
A vehicle dynamics control system as in claim 8 wherein each submodule has a portion in said first controller area and a portion in said second controller area.
Claim 11
Dependent Claim
28 words
A vehicle dynamics control system as in claim 1 wherein said means for applying a brake force at the individual wheels comprises brake actuators at the individual wheels.
Claim 12
Dependent Claim
32 words
A vehicle dynamics control system as in claim 1 wherein said means for applying a brake force at the individual wheels comprises means for reducing wheel drive torque produced by the engine.
Claim 13
Dependent Claim
34 words
A vehicle dynamics control system as in claim 1 wherein said means for applying a brake force at the individual wheels comprises means for adjusting the transmission ratio between the engine and the wheels.
