Abstract
The invention relates to relates a steering system and to a steering method which counteract a mistake that inexperienced drivers frequently make. The invention relates to a system (12, 14, 6) for determining the transversal slip that occurs at the steerable wheels (2). A electronic control system (6) is used to determine an upper threshold value for said transversal slip. If the transversal slip exceeds said threshold value, an augmentation of the angle of lock is counteracted by either limiting said angle of lock and/or outputting a warning signal that can be perceived by the driver.
Claims20
A steering system for an undermodulatedly designed motor vehicle with two steerable wheels (2), a steering wheel (4) actuatable by a driver of the vehicle against one of a steering force action and a steering torque, at least one actuator (8) for an angle of lock of the two steerable wheels, and the at least one actuator (8) acting upon the two steerable wheels (2) and being modulatable by an electronic control device (6);
- wherein a device (12, 14, 6) determines a transversal slip occurring on the steerable wheels (2), the electronic control device (6) determines an upper threshold value for the transversal slip, and at least one means (16, 8) is provided which serves to counteract further enlargement of the angle of lock when the determined transversal slip is greater that the upper threshold value.
