A method controls a power train of a vehicle immobilized in a parking position, the vehicle being provided with a parking brake device for immobilizing the vehicle and at least one electric motor. The method includes detecting the slope direction and/or slope data when the parking brake device is in an actuated position, detecting that the parking brake device has switched from the actuated position to a released position, and applying a motor torque setpoint to the electric motor in accordance with the detected slope direction and/or slope data.

An apparatus for brake control may include a first valve group comprising valves included in a hydraulic circuit configured to supply hydraulic pressure for braking of a vehicle; a first valve drive circuit configured to drive the valves comprised in the first valve group; a first backward voltage prevention element connected between a power source and the first valve drive circuit to block backward voltage generated at a power source side of the first valve drive circuit; a second valve group included in the hydraulic circuit and comprising valves included in the hydraulic circuit; a second valve driving circuit configured to drive the valves comprised in the second valve group; and a second backward voltage prevention element connected between a power source and the second valve drive circuit to block backward voltage generated at a power source side of the second valve drive circuit.

A vehicle includes a powertrain and an electric parking brake. A controller activates the electric parking brake in response to the powertrain transitioning to an off state that inhibits production of propulsive torque during an ignition cycle when a vehicle speed is less than a predetermined speed and in a presence of conditions that inhibit the powertrain from transitioning to an on state that permits production of propulsive torque.
