Abstract
A skid-control traction-control system is provided for a motor vehicle including at least two driven wheels connected by a differential mechanism, characterized by the provision of a skid-control solenoid valve operable--when the vehicle is decelerating and either driven wheel has a rotational deceleration which differs from an estimated predetermined amount--for automatically deactivating the brakes associated with both driven wheels, in combination with a system operable--when the vehicle is accelerating and one driven wheel has a rotational velocity which differs from the other by a predetermined amount--for automatically braking only the faster driven wheel, thereby causing torque to be transferred to the slower wheel via the differential mechanism.
