Locking / releasing device for brakes and control method of ABS equipped vehicle {A method and apparatus for controlling a brake for vehicles installing an ABS system}

The present invention relates to a device for locking / releasing a brake of a vehicle equipped with an ABS system and a method of controlling the same. Particularly, the present invention relates to an ABS system in which a vehicle is equipped with an ABS system until the rotational speed of the engine reaches a predetermined value when the hill is started. Brake lock / unlock for ABS-equipped vehicles that sends a brake lock request signal to the control unit and requests that the brake be released when the engine throttle valve opens and the engine speed is above the set value, thereby preventing the vehicle from being pushed back when the vehicle is on a hill. An apparatus and a method thereof are provided.

The brake system of a vehicle is usually composed of a foot brake and a hand brake. The dual hand brake is a brake used for stopping or parking. In some cases, the brake system is used as an auxiliary brake to prevent the vehicle from being pushed when the hill is kicked off. Is also used.

In most cases, however, the vehicle is pushed back when the vehicle is stopped from a hill, and a lot of effort is put into preventing the fall by using the auxiliary brake as described above, and in some cases, the starting is turned off due to inexperienced operation. There was a problem.

The present invention is to solve the above-mentioned drawbacks, and to provide a brake control system that prevents a vehicle equipped with an ABS system from being pushed back when the vehicle is on a hill.

The present invention sends a brake lock request signal to the ABS control unit until the engine speed set value is reached when the vehicle is equipped with the ABS system, and the engine throttle valve is opened and the engine speed becomes higher than the set value. This is achieved by requiring release of the brake.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a brake lock / release device of an ABS-equipped vehicle of the present invention. The present invention provides a speed sensor 1, a brake switch 2, a clutch switch 3, and a throttle position of an automobile. In a vehicle equipped with an ABS system including a sensor 4, an engine speed sensor 5, a brake system 6, and an ABS control unit 7, a vehicle inclination for detecting an inclination of the vehicle A sensor 10; An engine control unit 20 for signal processing and control of the sensors and switches; A communication system (30) for signal linkage between the engine control unit (20) and the ABS control unit (7); The technical feature is that it consists of an actuating switch 40 for activating / deactivating the component.

FIG. 2 is a flowchart illustrating an operation step of a control method of a brake lock / release device of an ABS equipped vehicle according to the present invention, the first step S1 of operating an engine of a vehicle; A second step S2 of determining whether the operation switch 40 of the brake lock / release device of the ABS equipped vehicle is turned on; A third step S3 of determining whether the inclination of the vehicle is greater than or equal to a specific inclination; A fourth step S4 of determining whether the throttle position sensor is closed and the vehicle speed is in a stopped state, and whether the brake is pressed, that is, whether the brake switch 2 is turned on; A fifth step (S5) of performing brake lock by transmitting a lock signal to the ABS control unit (7) from the engine control unit (20) when the condition of the fourth step is satisfied; A sixth step S6 of determining whether the operation switch 40 is turned on; When the operation switch 40 is turned on in the sixth step S6, whether a specific delay time has passed since the clutch switch 3 is operated, and whether the detected value of the throttle position sensor 4 is greater than zero. Determining a seventh step (S7); An eighth step (S8) of determining whether the engine revolutions per minute is greater than a specific value when the condition of the seventh step (S7) is satisfied; When the condition of the eighth step (S8) is satisfied, it consists of a ninth step (S9) of transmitting a brake release signal to the ABS control unit 7 to release the brake and returning to the first step (S1). If the operation switch 40 is not turned on in the sixth step S6, the process proceeds to the ninth step S9, and if the conditions of the seventh step S7 and the eighth step S8 are not satisfied. The method returns to the fifth step S5.

In addition, when the conditions of the second step S2, the third step S3, and the fourth step S5 are not satisfied, the ABS control unit 7 controls the brake system 6 to be controlled. It is further configured as a step P1.

Hereinafter, the operation and effects of the present invention will be described with reference to FIGS. 1 and 2.

First, it is determined whether the operation switch 40 is turned on while the engine is operating (S2), and the third step (S3) of determining whether the inclination of the ground on which the vehicle is placed is above a certain angle through the vehicle inclination sensor 10. Perform

The fourth step S4 of determining whether the brake switch 2 is turned on while the throttle position is closed and the vehicle is in a stopped state while satisfying the above determination condition is performed. If the condition is satisfied, the above state is determined as a situation in which the vehicle can be pushed back, and the brake control signal is sent to the ABS control unit 7 to perform the fifth step S5 of locking the brake.

This prevents the vehicle from being pushed back because the brakes are locked when the car is on a hill or when you are about to start.

Thereafter, after determining whether the operation switch 40 is turned on (S6), the driver determines whether the throttle is opened while the delay time from operating the clutch switch 3 is longer than a specific time (S7). At this moment, the driver detects that the driver is about to start from the hill and the engine revolutions per minute (RPM) exceeds a specific value (S8). ) To release the brake, and the driver can start the vehicle.

The present invention as described above is an invention having the effect of preventing the vehicle equipped with the ABS system from being pushed back at the time of departure from the hill.
