Method and device for electronically controlling a vehicle deceleration in dependence on a differential slip between two vehicle axles
First Claim
1. A method for controlling deceleration of a vehicle comprising an anti-lock braking system (“
- ABS”
), a first axle, and a second axle, the method comprising;
detecting at least one of a target vehicle deceleration specified by the driver and an actual vehicle deceleration; and
actuating the ABS such that a detected actual differential slip corresponds to a target differential slip,wherein the actual differential slip indicates a difference in a rotational behavior of the first axle relative to the second axle, andwherein for at least a portion of a domain of the actual vehicle deceleration or the target vehicle deceleration, the target differential slip is inversely dependent on a magnitude of at least one of the detected actual vehicle deceleration and the detected target vehicle deceleration, such that as the magnitude of the detected actual vehicle deceleration and/or the magnitude of the detected target vehicle deceleration increases, the target differential slip decreases.

Abstract
A method for controlling a vehicle deceleration depending on a differential slip between two vehicle axles in a vehicle with an ABS brake system includes detecting at least one of a target vehicle deceleration specified by the driver and an actual vehicle deceleration; and controlling a braking pressure on wheel brakes of a vehicle axle to be controlled by actuation of ABS brake valves in such a way that the braking pressure on the wheel brakes of the vehicle axle to be controlled is controlled depending on a detected actual differential slip, so that the actual differential slip corresponds to a target differential slip. The actual differential slip indicates a difference in a rotational behavior of the vehicle axle to be controlled relative to a further vehicle axle. The target differential slip is dependent on at least one of the detected actual vehicle deceleration and the detected target vehicle deceleration.
