Method and device for improving the handling characteristics of a vehicle while braking during cornering
First Claim
1. Method of improving the driving performance of a vehicle when braking during cornering, comprising the following steps:
- detecting cornering and the direction of cornering, determining the rolling characteristics of individual wheels, and if necessary, influencing the braking pressure of the brake on one wheel or on several wheels according to the rolling characteristics of these wheels, checking the driving condition of the vehicle with respect to whether instability prevails, modifying the braking pressure of at least one brake of a wheel when an instability is detected during cornering which persists beyond a predetermined time period, and identifying a critical lane change if, within a defined or definable duration after cornering in the unstable condition in one direction, there is detected cornering in the unstable condition to the other direction, and further measures are initiated upon the detection.

Abstract
A system including a method for improving the driving performance of a vehicle when braking during cornering comprises the following steps: detecting cornering and the direction of cornering, determining the rolling characteristics of individual wheels, if necessary, influencing the braking pressure of the brake on one wheel or on several wheels according to the rolling characteristics of these wheels, checking the driving condition of the vehicle with respect to whether instability prevails, and modifying the braking pressure of at least one brake of a wheel when an instability is detected during a cornering maneuver extending for a time period that reaches a threshold time period. A device for improving the driving performance of a vehicle while braking during cornering comprises a detection device for detecting a cornering maneuver and the direction of cornering, a determining device for determining the rolling characteristics of individual wheels, an influencing device which optionally influences the braking pressure of the brake on one wheel, a checking device for checking the driving condition of the vehicle as to whether instability prevails, and a modifying device for modifying the braking pressure of at least one brake of a wheel when an instability is detected during cornering extending for a time period which reaches a threshold time period.
