When a vehicle is suddenly stopped by turning off an ignition key switch on a way of a slope road, a braking force maintaining control is not preformed, and it often occurs that the vehicle moves down along the slope road. To prevent such occurrence, an electro-mechanical braking device for maintaining the braking force is provided so that the vehicle is parked securely. The electro-mechanical braking device includes a parking brake mechanism for maintaining the brake force even when an ignition key switch (power supply switch) of the vehicle is turned off. When the power supply switch (ignition key switch) of the vehicle is turned off with a braking pedal being stroked or a braking operation signal being present, the parking-brake mechanism is activated (the brake force is maintained).
An electro-mechanical braking control device comprising:
An electro-mechanical braking device for electrically generating a braking force in response to a control signal from a control device performing a control processing based on at least one of a stroking force and a stroking speed of a braking pedal, and a braking operation signal,
A control method for controlling an electro-mechanical braking device including an electro-mechanical brake for electrically generating a braking force in response to a stroking force or a stroking speed of a braking pedal, or a braking operation signal, and a parking brake mechanism for maintaining the braking force when power is not supplied to said electro-mechanical brake or a control signal is not applied thereto,
