Abstract
A method for the controlled power activation of an electromechanical braking system in a motor vehicle where the maximum power available is less than the nominal capacity includes the step of activating brake force-generating units of the braking system individually or in subgroups in succession to one another. The brake force-generating units are in each case activated with a power level corresponding to a portion of the maximum power available. The portion of the maximum power available is sufficient for the individual unit to function at least partially.
Claims7
A method for a controlled power activation of an electromechanical braking system in a motor vehicle, the method which comprises:
- providing, in a motor vehicle, an electromechanical braking system having brake force-generating brake units activateable in subgroups, the subgroups respectively including at least one of the brake force-generating brake units;
- sequentially activating the subgroups of the brake force-generating brake units if an available maximum power is below a nominal power capacity, and activating the brake force-generating brake units of the subgroups in each case with a given portion of the available maximum power such that the given portion of the available maximum power is sufficient for the brake force-generating brake units of the subgroups to function at least partially;
- adjusting each of the brake force-generating brake units of the subgroups to a first power level for an activation of the brake force-generating brake units of the subgroups;
- and
- subsequently supplying each of the brake force-generating brake units of the subgroups with a second power level smaller than the first power level for maintaining a brake force.
