A system for determining the height of the center of gravity of a vehicle includes an arrangement configured to determine a difference between wheel contact forces, an arrangement configured to determine a transverse acceleration, an arrangement configured to determine comparison values which compares the change in the difference between wheel contact forces with the change in the transverse acceleration, and an arrangement configured to evaluate a roll model which determines the height of the center of gravity from the comparison values. Furthermore, a corresponding method is for determining the height of the center of gravity of a vehicle.

A solenoid valve control is described, having a switching output stage for controlling a solenoid valve, an arrangement for preselecting a valve opening time, and an arrangement for preselecting a pressure over the valve. Also provided is an arrangement for determining a valve control time from the preselected valve opening time and the preselected pressure over the valve. A method is also described for controlling a solenoid valve which can be carried out to advantage with this solenoid valve control.

Solenoid valve control and method of controlling a solenoid valve

A method and a system for limiting an engine torque of vehicles to a maximum value. In the method, signals representing wheel torques from wheel sensors at the drive train are acquired, the wheel torques, differentiated according to driving situations which can have a harmful influence on the transmission, differential or torque converter, then being checked for a wheel-torque value which is too high. If too high a value is found, the engine torque is limited or reduced.

A method and a system for operating a brake system of a motor vehicle having traction control are described. The brake system contains sensors which are assigned to the individual vehicle wheels and with which a quantity representing at least the driving and/or braking forces acting between the road surface and the vehicle wheel is detected for the respective vehicle wheel. For operation of the brake system having traction control, pressure quantities which describe the brake pressure established for the respective vehicle wheel are analyzed. The pressure quantities are determined as a function of the quantities detected by the sensors.

The system serves to control the brakes of at least two wheels of a vehicle, preferably mounted on the same axle. Means are provided for controlling the brake pressure at the so-called low wheel to prevent it from locking after it has been recognized that this wheel is showing a tendency to lock. In addition, detection means are provided for determining a variable which modifies and/or represents the driving dynamics of the vehicle. A corresponding threshold value is also derived for this variable. A comparison means is provided to compare the determined variable with the determined threshold value, and a comparison result is generated. Control means for controlling the brake system of the high wheel are provided, which, after it has been recognized that the low wheel is showing a tendency to lock, change the course of the brake pressure at the high wheel as a function of the determined comparison result.

System for controlling brake systems

The yawing motion, the float angle, the longitudinal velocity of the vehicle, the front wheel steering angle, and optionally the rear wheel steering angle are determined. When certain driving conditions are present, at least the variable representing the front skew stiffness is determined as a function of the determined variables. In an alternative embodiment of the invention, the detection of the float angle is omitted. The variable representing the front skew stiffness is then calculated as a function of the detected yawing motion and the detected longitudinal velocity of the vehicle and as a function of a fixed, predefined value representing the rear skew stiffness. This calculation, too, occurs only when certain driving conditions are present.

System for determining skew stiffness

The movement of a vehicle is controlled by actuating actuators which apply a braking force to the wheels. For this purpose, the rotational speeds of the wheels, the steering angle and at least one of the lateral acceleration and the yawing movement of the vehicle are detected. A first module is configured so that the actuators are actuated by means of the actuation signals with the effect of controlling a first variable. The second module is configured so that signals for influencing the actuation signals are formed with the effect of controlling a second control variable. In order to obtain this second control variable, at least the variable which represents the steering angle is processed. The second controller component brings about a control of a variable which is determined at least as a function of the lateral movement or the yawing movement of the vehicle.

Modular vehicle dynamics control system

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.
