Title: Vehicle wheel slip controller
Inventor: LEPPEK KEVIN GERARD
IPC: B60T8/62
Filed: 1988-10-03
Abstract: Vehicle traction wheel spin is controlled by an add-on brake pressure modulator (12, 16) that functions in addition to limit the brake pressure applied to the vehicle wheels during anti-lock braking. A piston (42) in the pressure modulator is moved in a cylinder (44) to regulate the braking pressure. During non-operating conditions of the pressure modulator the piston is moved to provide minimum cylinder volume to be in condition to be moved to withdraw fluid from the brake apparatus to limit brake pressure. (See Fig 3A). When a potential for excessive spin of a driven wheel is detected, the piston is moved to increase the volume of the cylinder (44) to draw in braking fluid from a brake fluid reservoir. (see Fig 3B). The pressure modulator is then in condition to apply regulated brake pressure to limit excessive slip. When the potential for excessive slip no longer exists, the piston is controlled to provide minimum volume while returning the brake fluid to the brake fluid reservoir. The pressure modulator is then again in condition for limiting brake pressure. The modulator piston (42) is preferably movable through screw gearing (40, 44) by an electric motor. <IMAGE>
