Abstract
A device and a method control units arranged in the power train of a motor vehicle. The vehicle has electrically actuated, wheel brakes, preferably designed with one or two motors. A control arrangement is provided that controls the functions of at least one of the units arranged in the power train and/or the function of the wheel brakes in an open or closed loop and which influence the potential of at least one of these units in response to a signal received. At least one electric storage arrangement is effectively connected to the electrically actuated brakes to supply them with power. The device and method utilize a diagnostic arrangement through which the potential of at least one of the energy storage arrangement is detected.
Claims22
A device for controlling units situated in a power train of a vehicle, the vehicle including energy storage arrangements supplying power to electrically actuated wheel brakes, the device comprising:
- a diagnostic arrangement detecting a first potential of at least one of the energy storage arrangements and generating a signal as a function of the detected first potential;
- and
- a control arrangement performing, in one of an open-loop manner and a closed-loop manner, at least one of:
- in response to the signal, adjusting a second potential of at least one of the units to substantially correspond to the detected first potential for enhancing driving safety conditions, and
- in response to the signal, applying a predetermined braking effect by controlling the electrically actuated wheel brakes.
A method for controlling units arranged in a power train of a motor vehicle including electrically actuated wheel brakes and at least one energy storage arrangement supplying power to the electrically actuated wheel brakes, the electrically actuated wheel brakes including at least one motor, the method comprising the steps of:
- detecting a first potential of at least one of the at least one energy storage arrangement;
- generating a signal as a function of the detected first potential;
- and
- in response to the signal, adjusting a second potential of at least one of the units to substantially correspond to the detected first potential for enhancing driving safety conditions.
