Abstract:
A method for providing a traction control in a motor vehicle equipped with an anti-lock system, comprising the steps of:detecting a wheel speed of at least each driving wheel of the motor vehicle;providing a valve arrangement for each driving wheel, each valve arrangement being capable of performing a pressure building operation, a pressure maintaining operation, and a pressure reducing operation; andwhen an unallowable slip occurs on at least one driving wheel, modulating a brake pressure built up by a driver of the motor vehicle in a wheel brake associated with the at least one driving wheel exhibiting the unallowable slip by setting the valve arrangement associated with the at least one driving wheel exhibiting the unallowable slip to a traction control position, wherein the brake pressure modulation occurs only if a brake pedal of the motor vehicle is being depressed by the driver and at least one of the following criteria is satisfied:a) the driver has actuated an additional switching element,b) a speed of the motor vehicle is less than a predefined threshold value,c) a predefined time period has not elapsed since a beginning of the traction control, andd) the driver has actuated a gas pedal of the motor vehicle.
