Problems solved by technology

This leads to very complex applications, most importantly the complexity of the mutual protection of the individual subsystems with respect to each other, and to functional restrictions on the individual subsystems (i.e., since each subsystem cannot restrict or hinder other subsystems, each subsystem the system cannot ideally achieve its control objectives)

Embodiment Construction

[0019] FIG. 2 shows a driving dynamics control 10 according to the invention including a signal distributor 11 . The signal distributor receives input data from the vehicle 12 (sensed variables such as lateral acceleration, sideslip speed / yaw speed), input data from the driver 13 (indicated via steering angle and / or accelerator pedal position, brake pedal position driver request) and input data from the environment 14 (if detectable, such as the inclination of the road surface, the coefficient of friction of the road surface, etc.). The signal distributor 11 is connected to a decision unit 15 (driving state detection, driver request recognition) and to the manipulated variable distributor or decision unit of the central driving state controller 16 and the subsystems 17 to 20 . System input data (from) the driver, the vehicle and the environment are provided to the decision unit 15, and from these signals the decision unit 15 determines the driver's desired vehicle nominal perf...

Abstract

The invention relates to a driving dynamics control system for vehicles, involving at least one signal distribution, to which vehicle data, environmental data and data regarding the driver's intention are fed in the form of input data, and a number of controllable or regulatable subsystems, which modify the dynamics of the vehicle such as a driver-independent adjustable steering system, a driver-independent adjustable chassis, a driver-independent adjustable brake, and a driver-independent adjustable drive train. The invention is characterized in that: the data of the signal distribution are fed to a central determining unit (driving condition recognition, driver's intention recognition); the central determining unit determines a central control target from the data of the signal distribution, and these items of data regarding the central control target are fed to a central regulating variable distribution or to a central driving condition controller that, while interactively communicating with the subsystems, controls these subsystems in such a manner that the control target is converted by the subsystems on the vehicle.

Description

technical field [0001] The invention relates to a driving dynamics / dynamics (Fahrdynamik) control system for a vehicle comprising at least one signal distributor to which vehicle data, environmental data and data concerning driver requests are fed as input data In at least one signal distributor; also includes a plurality of controllable or adjustable subsystems that adjust vehicle dynamics, such as a steering system that can be adjusted independently of the driver, a chassis that can be adjusted independently of the driver, brakes and a drive train that can be adjusted independently of the driver. Background technique [0002] Both comfort and safety engineering are increasingly important in vehicles. As a result, vehicles are increasingly equipped with electronic and electromechanical components or subsystems. For plausibility of the sensor signals, processing of the signals, calculation of adjustment signals and regulation of the actuators of the subsystems, each subsys...
