Abstract

A method for reducing the braking distance for a vehicle having an anti-lock braking mechanism (ABS) and a hydraulic braking system detects a brake pressure requested by the vehicle's driver (Prequested), and calculates the brakes pressure values at which the wheels of the vehicle lock. A maximum brake pressure value of these different brake pressure values is then compared with the driver's requested brake pressure value (Prequested). If the requested brake pressure value is much higher than the maximum brake pressure value, then the actual brake pressure applied at different wheels (Pactual) is set to a level below the requested brake pressure (Prequested), but still higher than the maximum brake pressure value. This reduces the amount of work required to be done by the ABS in pumping the excessive brake fluid out of the braking system of the vehicle, and allows for precise control of ABS mechanism during wheel slip conditions.
