Description

Side brake auto release device and method

The present invention relates to a device and a method for automatically releasing the side brake, in particular, when the parking is pulled out two or three times when the double parking or the distance between the front and rear car is too narrow to escape from the parking place. The side brake is released for a predetermined time, the vehicle can be moved, and especially in a region with high inclination, the side brake automatic release device and method for determining the release of the side brake according to the location so that the side brake is not released due to the characteristics of the region .

In the case of general cars, the side brake is applied to prevent the vehicle from moving after parking. When the driver puts a side brake on the car, the car can't move unless it is forced to use physical force from the outside. Due to this fact, the vehicle parked between the vehicle and the vehicle has to be pushed out slightly in front of and behind the vehicle, which damages the exterior of the vehicle. On the other hand, if the side brake is applied during double parking, other vehicles cannot move. There was a problem to wait until the owner came.

An object of the present invention is to solve the above conventional problems, in particular, by mounting the switch on the door handle of the vehicle to pull the door handle a predetermined number of times (for example three times) to operate the door handle switch signal Is applied to the electronic control unit (hereinafter referred to as ECU), and the ECU, which receives the signal from the door handle switch, checks various situations of the vehicle, and specifically checks the slope of the terrain to release the side brake. The side brake automatic release device which makes it possible to judge whether it is okay to release the side brakes and release the side brakes for a predetermined time (for example, 3 minutes) so that the vehicle can be moved without removing the side brakes inside the vehicle; To provide a way.

In order to achieve the above object, the automatic side brake release device of the present invention includes: a door handle switch unit mounted on the door handle and transferring a side brake release signal input from the outside to the ECU by an operator; A signal input unit for transmitting a signal input by a mechanical switch, such as an input of a ignition key, a door lock signal, or a parking position signal of a side brake, to the ECU; A vehicle speed sensor for inputting, as a numerical value, the movement state of the vehicle to the ECU when the vehicle is running or the vehicle is moved by a force other than manpower; A hardness check sensor which checks the slope of the terrain that is currently parked and inputs it to the ECU; A side brake control ECU which determines whether to release the side brake by integrating data applied from the components; A motor driving relay unit which drives the motor according to a signal applied from the side brake control ECU to release the side brake or fills the side brake; The technical configuration is characterized by including a timer for checking the time to release only for a predetermined time when the side brake is released.

Hereinafter, an embodiment according to the technical idea of the apparatus and method for automatically releasing the side brake of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

<Example>

As shown in FIG. 1, the door handle switch unit 10 is mounted to the door handle to apply a side brake release signal input from the outside to the ECU 50 by the operator, and the signal input unit 20 is connected to the start key. Signals input by a mechanical switch, such as an input, a door lock signal, a parking position signal of a side brake, etc. are applied to the ECU 50, and the vehicle speed sensor 30 is used when the vehicle is in operation or when the vehicle is moved by a force other than manpower. The state of movement is input to the ECU 50 as a numerical value, the hardness check sensor 40 checks the inclination of the terrain that is currently parked and applies it to the ECU 50, the side brake control ECU 50 is the door handle Comprehensive data from components such as switch 10, signal input unit 20, vehicle speed sensor 30, hardness check sensor 40, etc. are determined to release the side brake, and the signal for the motor drive relay is determined. Part (60) The motor driving relay unit 60 drives the motor according to the signal applied from the side brake control ECU 50 to release the lock of the side brake or lock the side brake, and the timer 70 controls the side brake. The present embodiment constitutes the present invention by returning the side brake, which has been canceled after a predetermined time, to the original locked state after the predetermined time has elapsed so as to be released only for a predetermined time when canceling.

Hereinafter, the operation of the present embodiment configured as described above will be described in detail with reference to the accompanying drawings.

First, as shown in FIG. 1, when a driver of a vehicle A moves a vehicle B by a predetermined distance in a parking space, and then moves the vehicle A by pulling a door handle of the vehicle B a predetermined number of times, the door handle switch ( In 10), a signal is applied to the side brake control ECU 50 to release the side brake for a while.

The side brake control ECU 50, which receives the signal from the door handle switch 10, checks the signal applied from the signal input unit 20. In this case, in the signal input unit 20, the start key is first applied to the key box. It checks whether it is inserted, whether the door is currently locked, and whether the side brake is in the parking position.

When only one signal is turned on as a result of checking the signal in the signal input unit 20, the signal input unit 20 applies the signal to the brake control ECU 50 via the data bus line, while the vehicle speed sensor 30 is currently operating the vehicle. Data is applied to the side brake control ECU 50 as a numerical value when the vehicle is moved by a force other than the manpower or manpower.

At this time, the signal of whether the vehicle is moving or not is compared with the data obtained from the vehicle speed sensor 30 is compared with the reference value in the comparator 88 shown in FIG. The central processing unit 99 determines that the vehicle is moving.

Meanwhile, the hardness check sensor 40 checks the slope of the terrain where the vehicle is currently parked and applies it to the side brake control ECU 50. The side brake control ECU 50, which receives signals and data from the door handle switch 10, the signal input unit 20, the vehicle speed sensor 30, and the hardness check sensor 40, analyzes all data and signals and analyzes the side brake. If the condition may be terminated, a signal is applied to the motor driving relay unit 60 to drive the motor M for releasing the side brake.

The motor (M) is to rotate the motor (M) in the forward or reverse direction in accordance with the signal applied from the motor drive relay unit 60, as shown in Figure 3, the forward direction in accordance with the signal output from the two-pole relay The motor rotates in the reverse direction. This is shown in the table below.

At this time, the timer 70 checks the time from the time from which the signal is applied to the motor drive relay 60 to the predetermined time by the side brake control ECU 50, and when the predetermined time passes, the timer 70 determines the side brake control ECU 50. The side brake control ECU 50, which has received a signal from the timer, applies a signal for locking the side brake to the motor driving relay 60 to return the side brake to the locked state. Will be returned.
