A method for determining the float angle of a motor vehicle is described, a yaw sensor determining the yaw rate of the motor vehicle. According to this method, the direction of the velocity in the center of gravity of the vehicle in particular is determined by a frequency analysis of the signals received by a GPS receiver located in the motor vehicle, and the float angle is determined as a function of at least the yaw rate and the direction of the velocity of the motor vehicle.

A method for controlling the handling characteristics of a vehicle, including the steps of ascertaining setpoint values that are associated with specific controlled variables, and measuring forces at wheels of the vehicle, the controlled variables being forces or torques, actual values associated with the setpoint values being calculated from the forces measured at the wheels of the vehicle, and the ascertained setpoint values and the calculated actual values being used as input values of a control system. Also described is a system for controlling the handling characteristics of a vehicle.

A method of controlling the braking force in a vehicle has the following steps: determining actual values of controlled variables; determining setpoint values of controlled variables; comparing the actual values with the setpoint values, thereby obtaining comparison results; and influencing wheel forces on the basis of the comparison results, wheel forces being used as controlled variables, the actual values of the wheel forces being determined by a sensor system which measures the wheel force, torques having a modulation frequency being generated at the wheels, whereby the slip of the wheels and the wheel force of the wheels are modifiable, the slip of the wheels and the wheel forces of the wheels are analyzed, and the setpoint values of the wheel forces are determined from the analysis of the slip of the wheels and the wheel forces of the wheels. A system for controlling the braking force in a vehicle is also described.

In a monitoring device for a vehicle including a drive engine, the monitoring device monitors the power train of the vehicle. The monitoring device includes an arrangement configured to generate a first signal which indicates a setpoint drive torque, a sensor system which measures an actual drive torque and generates a second signal which indicates the actual drive torque, and an analyzer which receives the first signal and the second signal in order to identify possible fault conditions in the power train of the vehicle. Furthermore, a method is for monitoring the power train of a vehicle, and a device is for performing the method.

A force sensor having a substrate for measuring forces is provided, on which substrate a first path and a second path for travel of acoustic surface waves are arranged. The two paths are arranged essentially parallel to one another and their lengths are different. An effect of a force on the substrate is detectable by measuring a time needed for an acoustic surface wave to travel at least one of the first and second paths.

A braking torque regulator for a vehicle includes a braking energy recovery arrangement that is able to generate a first braking torque which may not exceed a maximum first braking torque, and a mechanical brake system that is able to generate a second braking torque. The braking torque regulator is supplied with a setpoint braking torque, and the first braking torque and/or the second braking torque is regulated by the braking torque regulator so that the setpoint braking torque is used to correct an actual braking torque detected by a sensor system. A method is for regulating a braking torque in a vehicle and circuitry for a braking torque regulator for a vehicle.
