System and method for monitoring the traction of a motor vehicle
First Claim
1. A system for monitoring the traction of a motor vehicle having at least two wheels (12), comprising:
- at least one wheel-force sensor (10) assigned to a wheel (12) that detects at least one wheel-force component of the respective wheel (12) acting essentially between the road surface and tire contact surface, and that emits a signal (Si, Sa) representing the wheel-force component; and
an evaluation device (14) that processes the signal (Si, Sa) representing the wheel-force component of the wheel (12), wherein the evaluation device (14) evaluates when the wheel (12) in question is lifting off according to the processing results.

Abstract
The present invention relates to a system for monitoring the traction of a motor vehicle having at least two wheels (12) that includes at least one wheel-force sensor (10) which is assigned to a wheel (12), detects at least one wheel-force component of the respective wheel (12) acting essentially between the road surface and tire contact surface, emits a signal (Si, Sa) representing the wheel-force component, and includes an evaluation device (14) that processes the signal (Si, Sa) representing the wheel-force component of the wheel (12). According to the invention, the evaluation device (14) evaluates when the relevant wheel (12) is lifting off according to the processing results. The invention furthermore relates to a method for monitoring traction.

- 13. A system for controlling and/or regulating the handling of a motor vehicle having at least one tire (32) and/or one wheel (12), a force sensor (20, 22) located in the tire (32) and/or on the wheel (12), especially on the wheel bearing, and a wheel variable that represents the tendency of the wheel (12) to lift off from the roadway and that is determined in dependence upon of the output signals of the force sensor, and this wheel variable is used for the control and/or regulation of the handling.

14. A method for monitoring the traction of a motor vehicle having at least two wheels, comprising the following steps:
-
detection (S01) of at least one wheel-force component acting essentially between the road surface and tire contact surface on at least one wheel; and
processing (S02, S03, S04, S05, S06, S07) of the detected wheel-force component, wherein the processing step (S02, S03, S04, S05, S06, S07) includes an evaluation (S03, S04, S05, S06, S07) of the tendency of the relevant wheel to lift off in accordance with the detected wheel-force component. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
