A vehicle control apparatus and a method for controlling the same are disclosed. The vehicle control apparatus includes an inputter, a determiner, and a controller. The inputter receives an automatic vehicle hold (AVH) switch operation signal from an AVH device, and receives a current vehicle movement value sensed by a sensing device and a current vehicle brake force value of a brake device that generates brake force in response to activation of the AVH device. The determiner determines whether the received AVH switch operation signal transitions from an ON state to an AVH entry state, determines whether vehicle movement occurs on the basis of the received current vehicle movement value during an AVH retention time in the AVH entry state, and determines that the current vehicle brake force value is in an abnormal state when vehicle movement occurs. The controller receives the current vehicle movement value and the current vehicle brake force value, and transmits a command for judgment to the determiner.

A method for operating an electropneumatic parking brake system of a vehicle combination, which includes a tractor vehicle and a trailer vehicle, includes activating, after a parking operation and braking of the vehicle combination, a trailer check function in a standstill state. The trailer check function enables a check as to whether, in the case of a decrease in the braking action of the trailer vehicle, the vehicle combination can be held in a stationary manner solely by way of the braking action of a parking brake of the tractor vehicle. The trailer check function is carried out automatically when a vehicle combination has been braked in a stationary manner independently by way of an automatic parking function.

A motor vehicle has an electronically controllable parking lock and an electronically controllable parking brake, which can be controlled individually or in combination. A device having an electronic control unit and a central operating element associated with the parking lock and the parking brake is provided. When the motor vehicle is at a standstill and the central operating element is actuated, the parking lock and the parking brake can be controlled in a specific type of parking-lock and/or parking-brake activation. In a first specific type, during a first actuation of the central operating element, at least the parking brake is automatically activated first. If the central operating element is then re-actuated within a predefined time window, or if the central operating element remains actuated for a predefined minimum time period, the driver is offered at least one possibility of manually selecting a specific type of parking-lock and/or parking-brake activation.

A braking force control apparatus for a vehicle has a control unit that executes a braking force reduction control that controls a braking device such that a braking force is gradually reduced when it is determined that a drive request for driving the vehicle is generated during execution of the braking force holding control for controlling the braking device to hold a braking force applied to the vehicle when the vehicle stops in the uphill direction on a slope. The control unit controls the braking device such that the braking force during execution of the braking force reduction control is larger when the drive request is generated by the driving support control than when the drive request is generated by the driver's driving operation.

In a method of controlling an electronic parking brake system to overcome an existing problem occurring in drive away release (DAR) mode, a control unit monitors whether or not a gear change signal is input in a vehicle stopped state, a P position state, or a parking brake applied state. When the gear change signal is input, an accelerator pedal input value of a driver is compared with a predetermined pedal input set value while a gear position of a transmission is maintained in the P position. When the accelerator pedal input value does not exceed the predetermined pedal input set value, a control operation is performed for automatic releasing of a parking brake. When a set time has passed after start of the control operation for the automatic releasing, a control operation of changing the gear position to the D position or the R position is performed.
