Method for controlling vehicle behavior during cornering and a braking system for implementation thereof
First Claim
1. A method for controlling the behaviour of an automotive vehicle during cornering comprising the steps:
- measuring rotational wheel speeds of an inner front wheel and an outer rear wheel of the vehicle, relative to the direction of cornering, establishing a wheel speed difference between the measured wheel speeds;
calculating the absolute value of the wheel speed difference between the measured wheel speeds, and responsive to the calculated absolute value of the wheel speed difference between the measured wheel speeds, applying a braking pressure to rear wheel brakes of the vehicle to obtain a desired vehicle behaviour.

Abstract
This method for controlling the behaviour of an automotive vehicle during cornering consisting in measuring the rotational wheel speed of the front and rear wheels of the vehicle, establishing the wheel speed difference between the front and rear wheels and modifying the brake pressure applied to the rear wheel brakes of the vehicle according to a vehicle behaviour to be obtained, comprises the steps of elaborating a function of the absolute value of the wheel speed difference between the inner front wheel and the outer rear wheel, considering the cornering direction and using said function to determine the brake pressure variations to be applied to the rear wheel brakes.

11. A braking system for a vehicle having front and rear wheels with brakes, the braking system comprising:
-
measuring means for measuring an inner front wheel speed and an outer rear wheel speed, considering the cornering direction, means for establishing the absolute value of the difference between the inner front wheel speed and the outer rear wheel speed, control means for controlling a brake pressure applied to the vehicle rear wheel brakes, and computing means for calculating a function from the absolute value of the difference between the inner front wheel speed and the outer rear wheel speed, said computing means being connected to said measuring means and said control means in order to modify the brake pressure applied to the rear wheel brakes using said variable, according to vehicle behaviour to be obtained.
