Abstract
A braking apparatus for a vehicle and control method thereof is disclosed herein. According to an embodiment of the present disclosure, a control apparatus for a vehicle is provided, the apparatus comprising: an electronic control unit which calculates a target demand value based on a pedal signal, determines whether the target demand value and an actual demand value are the same as a preset value, and controls to increase or decrease the actual demand value; a front wheel control unit which receives the actual demand value from the electronic control unit and controls braking of a front wheel electro-mechanical brake; and a rear wheel control unit which receives the actual demand value from the electronic control unit and controls braking of a rear wheel electro-mechanical brake.
Claims13
A method of controlling braking of a vehicle comprising (1) a front wheel control unit configured control braking of a front wheel electro-mechanical brake of the vehicle and (2) a rear wheel control unit configured to control braking of a rear wheel electro-mechanical brake of the vehicle, the method comprising:
- initializing an actual demand value for performing target braking by following a target demand value;
- initializing a timer that measures and outputs an elapsed time of a process;
- calculating the target demand value based on a pedal signal indicative of a brake pedal depression amount;
- determining whether the target demand value or the actual demand value does not correspond to a preset value;
- and
- in response to determining that the target demand value or the actual demand value does not correspond to the preset value, performing:
- increasing or decreasing the actual demand value by the preset value;
- and
- transmitting the increased or decreased actual demand value to the front and rear wheel control units to control the braking of front and rear wheel electro-mechanical brakes of the vehicle based on the increased or decreased actual demand value,
- wherein controlling braking of the front and rear wheel electro-mechanical brakes comprises (1) increasing an operation response of the front wheel electro-mechanical brake and (2) decreasing an operation response of the rear wheel electro-mechanical brake, the operation response of the rear wheel electro-mechanical brake being controlled to be smaller than that of the front wheel electro-mechanical brake.
A apparatus for controlling braking of a vehicle, the apparatus comprising:
- an electronic control unit configured to calculate a target demand value based on a pedal signal indicative of a brake pedal depression amount, determine whether the target demand value and an actual demand value correspond to a preset value, and control to increase or decrease the actual demand value;
- a front wheel control unit configured to receive the actual demand value from the electronic control unit and control braking of a front wheel electro-mechanical brake;
- and
- a rear wheel control unit configured to receive the actual demand value from the electronic control unit and control braking of a rear wheel electro-mechanical brake,
- wherein the electronic control unit is configured to increase an operation response of the front wheel electro-mechanical brake and decrease an operation response of the rear wheel electro-mechanical brake, the operation response of the rear wheel electro-mechanical brake being controlled to be smaller than that of the front wheel electro-mechanical brake, and
- wherein the electronic control unit is further configured to, in response to the target demand value or the actual demand value not corresponding to the preset value, increase or decrease the actual demand value by the preset value and transmits the actual demand value to the front wheel control unit and the rear wheel control unit.
