Process and device for front/rear braking distribution for a decelerating vehicle
First Claim
1. A process for braking a vehicle, the vehicle being fitted with a braking system including brake calipers which can be activated as a function of a target braking force and in which at least the activation of the calipers fitted to the rear wheels is decoupled from depression of a brake pedal, which depression corresponds to a braking force required by the driver, said process including:
- detecting a logical entry condition including at least a straight line test and a braking test, the straight line test being verified when the instantaneous lateral acceleration of the vehicle is less than a threshold acceleration and the braking test being verified when the brake pedal is operated by the driver; and
while the logical condition is detected, determining a base braking force from the required braking force;
calculating a corrected base braking force, by correcting the base braking force so that the corrected base braking force is greater than the base braking force; and
applying the corrected base braking force as target braking force for the rear wheels, so that the pitching motion of the vehicle is reduced on braking in a straight line.

Abstract
A process for braking a vehicle provided with brake calipers which can be activated as a function of a target braking force, at least the activation of the brake calipers of the rear wheels being decoupled from depression of a brake pedal, including: detecting a logical entry condition including at least a deceleration test verified when an instantaneous value of the deceleration of the vehicle is greater than a threshold deceleration; calculating of a rear base braking force by correcting the braking force required by the driver so that the rear base braking force is greater than the front base braking force; and applying the rear base braking force as target braking force for the rear wheels, so that the pitching motion of the vehicle is reduced on deceleration.
