Abstract
A method for operating a motor vehicle having two wheels, each of which is associated with a parking brake. The parking brakes are controlled as a function of a friction between the respective wheel and the ground.
Claims18
A method comprising:
- determining, in a motor vehicle comprising two wheels, a first friction value associated with a first wheel;
- determining, in the motor vehicle comprising the two wheels, a second friction value associated with a second wheel, wherein each wheel is associated with a parking brake and determining the first friction value and determining the second friction value is performed alternately;
- comparing the first friction value and the second friction value to determine a difference between the first friction value and the second friction value;
- and
- actuating each parking brake based upon the comparison of the first friction value and the second friction value, wherein the actuation includes at least control as a function of the difference between the first friction value and the second friction value and control as a function of a weight of the motor vehicle.
