Abstract
The invention relates to a drive slip control system in which the driven wheels are braked when spinning. Desired braking torques for the driven wheels are calculated using the actual speeds of the driven wheels and the desired speeds of the driven wheels. A first controller generates a first braking torque value MB1 using the difference .omega..sub.D in the actual speeds and the difference .omega.*.sub.D in the desired speeds. A second controller generates a second braking torque value MB2 using the sum .omega..sub.s of the actual speeds and the sum .omega.*.sub.s of the desired speeds. Both controllers have an integral component and a proportional component. The desired left braking torque MB.sub.L is calculated using the sum MB1+MB2. The desired right braking torque MB.sub.R is calculated using the difference MB2-MB1. The desired torques are then converted to control times for the brake pressure control valves.
