When the determination unit 104 determines that the vehicle can be started, the control unit 106 determines whether the vehicle is stopped or not to perform the operation of controlling the brake in accordance with the target brake pressure value so that the vehicle is stopped, The rollback state control mode for not performing the operation of controlling the wheel speed according to the value can be released.

The input unit 102 of the vehicle control apparatus 100 according to the first embodiment of the present invention is configured such that when the brake is controlled in accordance with the target brake pressure value in the control unit 106 or the wheel speed is controlled in accordance with the target vehicle speed value, It is possible to further input the parking performance information for determining whether the driver is in the driver's getting off state or the driver's start key off state outputted from the sensing device 10. [

At this time, the determination unit 104 can further determine whether there is an operator parking intention using the parking performance information input to the input unit 102, under the control of the control unit 106. [

For example, when determining whether there is an intention to perform driver parking, at least one of a door closing signal, which is a driver getting off state of the parking performance information, and a starter key off signal, 102 in accordance with the control of the control unit 106. [

The controller 106 controls the EPB apparatus 50 to operate the EPB (Electronic Parking Brake) apparatus 50 when the determination unit 104 determines that there is a driver parking permit.

When the control unit 106 receives the operation signal from the EPB apparatus 50 after the EPB apparatus 50 is operated, the control unit 106 does not perform the operation of controlling the brake in accordance with the target brake pressure value so that the vehicle is stopped, The rollback state control mode for not performing the operation of controlling the wheel speed in accordance with the target vehicle speed value is released to maintain the constant speed.
