A method of controlling travel behavior of a vehicle provides assistance to the driver of the vehicle before the occurrence of travel conditions which are difficult to control. A vehicle taking a curve tends not to follow the travel curve indicated by steering, often resulting in understeering as the travel speed increases. At very high speeds in a curve, such behavior can lead to conditions that are difficult for the driver to control. Rather than intervening when an unstable travel state is already present and control of the vehicle rendered difficult, as practiced in conventional systems and processes for the regulation of travel dynamics, the wheel brake of a rear wheel of the vehicle on the inside of the curve is already subjected to a weak braking force when a relatively minor tendency to understeer occurs, so that the understeering tendency is reduced or eliminated.

Method of controlling the travel behavior of a vehicle

Implementation of a travel dynamics control system in a vehicle is facilitated by integration of same with other operational components of an electrically controlled vehicle braking system. In an embodiment of the invention, travel dynamics electronics are integrated with the braking system electronics. In another embodiment, a yawing speed sensor and a transverse acceleration sensor are integrated with the travel dynamics electronics.

Vehicle braking system

A method for the processing of sensor signals in a digital electronic system including a microprocessor, in which computed magnitudes are derived from the signals emitted by the sensors, and wherein the magnitudes are compared with one another to recognize certain travel situations. In order to carry out these comparisons simply and reliably using an economical microprocessor and cost-efficient sensors while applying simple computing steps, the comparison of two magnitudes derived from the sensor signals is carried out first on a level of the representation of one magnitude, for example, an angular yawing speed, and a second time on a level of the representation of the other magnitude, such as, for example, a steering angle. By this method, one comparison result supports the other. The method is advantageously used in a vehicle with a device for the control of travel stability, and preferably for the recognition of reverse travel.
