BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In order to facilitate a thorough understanding of the present invention, the same reference numerals are used for the same means regardless of the number of the drawings.

1 is a view showing an anti-jamming device 100 for a commercial vehicle according to an embodiment of the present invention.

1, an anti-jamming device 100 for a commercial vehicle according to an embodiment of the present invention includes an information collecting unit 110, a magnetic valve 120, a controller 130, a switch 140, and a display unit 150. [ .

The information collecting unit 110 collects information on whether or not the brake pedal of the commercial vehicle is operated, information on whether or not the excavator is waiting, information on the neutral or singular gear, and information on the vehicle speed and torque. The torque value can be calculated from the engine speed (RPM). It is possible to directly calculate the torque amount and obtain the result determined in the transmission of the electronic vehicle.

The information collecting unit 110 may collect information by being connected to each component of the commercial vehicle as in the embodiment of the present invention. However, if there is an electronic control unit connected to the components, So that the above information can be collected. At this time, it is preferable to use a CAN (Controller Area Network) method as the communication method.

The information collection unit 110 provides the collected information to the control unit 130.

The magnetic valve 120 is connected to the brake and can operate the brake in response to a command from the control unit 130. [

When the magnetic valve 120 operates the brake, the commercial vehicle may be braked, and when the magnetic valve 120 releases the brake, the braking of the commercial vehicle may also be released.

The magnetic valve 120 for controlling the brake is illustrative and the present invention is not limited thereto. Other means other than the magnetic valve 120 may be used as long as the means for controlling the brake can be used.

The controller 130 controls the magnetic valve 120 according to the information provided by the information collecting unit 110.

The switch 140 determines whether or not the anti-jamming device 100 of the commercial vehicle operates.

The switch 140 may be formed at a position where the driver can easily press the inside of the driver's seat.

When the switch 140 is pressed, the anti-jamming device 100 of the commercial vehicle operates and the operation of the anti-jamming device 100 of the commercial vehicle can be displayed on the meter cluster or the display unit 150 .

When the depression of the switch 140 is released, the anti-jamming device 100 of the commercial vehicle does not operate.

The display unit 150 displays information provided from the control unit 130. The display unit 150 may be configured as a TFT-LCD screen separately from the instrument panel, but is not limited thereto and may be integrally formed with the instrument panel.

Next, a method for preventing the anti-jamming device 100 of a commercial vehicle including the above-described components from preventing the jamming of a commercial vehicle will be described in detail with reference to Fig.

2 is a view illustrating a method of preventing a commercial vehicle from being skidded according to an embodiment of the present invention.

Referring to FIG. 2, in step S200, the controller 130 determines whether an operation condition is satisfied. If the operating condition is satisfied, the process proceeds to step S210, and if the operating condition is not satisfied, the process proceeds to step S205.

The operating condition is a condition for the anti-jamming device 100 of the commercial vehicle to operate in the hill mode. The hill mode includes a first hill mode and a second hill mode to be described later.

The operating condition should be that the switch is pressed, the engine revolutions per minute (RPM) is at least 250, the brake pedal is in operation, the accelerator pedal is in standby state, the commercial vehicle speed is less than 0.5 km / h, Are all gear states except neutral and that the torque of the commercial vehicle is less than a predetermined level.

The RPM of the engine is not necessarily limited to 250 or more. The reason for setting the RPM to 250 is that the RPM is generally 250 or more when the commercial vehicle is started.

The speed is not necessarily limited to less than 0.5 km / h, and may be set arbitrarily to a speed close to zero.

All gears except neutral are intended to ensure that the conditions of use of the anti-skid device operate not only on the hill but also on a flat surface with slight bending or speed bumps and also when backing up against a hill.

The predetermined value, which is a reference relating to the above-mentioned torque value, can be set based on a value having a driving force such that the commercial vehicle is not pushed off the hill. This can be set on the basis of the highest slope of the hill, on the basis of the intermediate slope, or on the slope of the hill, respectively. When the values corresponding to the slopes of the hills are respectively set, the information collecting unit 110 further collects information on the slopes.

The reason for the torque of the commercial vehicle to be less than the preset level is that even if the speed is sufficiently reduced, there is no need to operate the anti-jamming device 100 of the commercial vehicle if the brake is released and there is sufficient torque before re-acceleration.

In step S205, the controller 130 determines whether the magnetic valve 120 is operating, and releases the operation if the magnetic valve 120 is in operation. Thereafter, the process returns to step S200.

In step S210, the controller 130 performs the first hill mode. The first hill mode means that steps S211 to S215 are performed.

In step S211, the controller 130 determines whether the switch is pushed. If the switch is in the pressed state, the process proceeds to step S212, and if the switch is not pressed, the process proceeds to step S205.

In steps S211 and S221, the driver releases the pushing state of the switch at any time even if the anti-jamming device 100 of the commercial vehicle operates, thereby releasing the operation of the anti-jamming device 100 of the commercial vehicle.

In step S212, the controller 130 determines whether the brake pedal operation is released. If the brake pedal operation is released, the process proceeds to step S213, and if the brake pedal operation is not released, the process returns to step S211.

According to the above steps, the magnetic valve 120 operates after the driver depresses the brake pedal on the slope, and remains in that state until the driver releases his / her foot from the brake pedal.

In step S213, the control unit 130 determines whether or not the vehicle is in the waiting state of the accelerator pedal. If the accelerator pedal is in the standby state, the process proceeds to step S214. If the accelerator pedal is not in the waiting state, the process proceeds to step S215.

According to steps S212 and S213, the driver releases his / her foot from the brake pedal and moves the foot to the excel pedal. When the driver steps on the Excel, the wait for the Excel pedal is canceled and the flow advances to step S215.

In step S214, the controller 130 records the elapsed time from the time when the operation of the brake pedal is released. If the recorded time is one second, the process proceeds to step S220. If the recorded time does not exceed one second, the process returns to step S211. In the embodiment of the present invention, one second is exemplary and may be set at a different time.

According to the step S214, the driver releases his / her foot from the brake pedal and waits in a state in which the accelerator pedal is not depressed. When the predetermined time has elapsed, the driver proceeds to the step S220.

In step S215, the controller 130 determines whether the torque value is equal to or greater than a predetermined value. If the torque value is equal to or greater than the predetermined value, the flow proceeds to step S230. If the torque value is not equal to or greater than the predetermined value, the flow returns to step S211.

According to step S215, the driver is in a state of stepping on the excel pedal, and step S215 will be repeated until sufficient torque is generated so that the commercial vehicle is not pushed off the hill unless the driver performs another action.

In step S215, the control unit 130 may calculate and provide the rotation speed information per minute, which can generate a torque equal to or greater than a preset value, on the display unit 150. [ The driver can see the number of revolutions per minute displayed on the display unit 150 and judge to what extent the accelerator pedal must be depressed to enable sufficient acceleration at the hill. As a result, it is possible to provide sufficient acceleration information in a short period of time and to induce the acceleration to be unnecessarily higher than necessary.

In step S230, the control unit 130 cancels the hill mode. To release the hill mode means to release the operation of the magnetic valve 120. After step S230 is performed, the process returns to step S205.

In step S220, the controller 130 performs the second hill mode. The second hill mode means that steps S221 to S223 are performed.

In step S221, the controller 130 determines whether the switch is pushed. If the switch is in the pressed state, the process proceeds to step S222. If the switch is not pressed, the process proceeds to step S205.

In step S222, the controller 130 determines whether the operation of the brake pedal is released and all of the conditions that the accelerator pedal is in the standby state are satisfied. If the condition is satisfied, the process proceeds to step S223, and if the condition is not satisfied, the process returns to step S210.

According to the step S222, the process returns to the first hill mode unless the driver stands by without pressing on the brake pedal or the accelerator pedal. If the driver does not press the brake pedal or the accelerator pedal, the process proceeds to step S223.

In step S223, the controller 130 determines whether the elapsed time is equal to or longer than three seconds. 3 seconds is an example, and the predetermined time lapse reference is not limited to 3 seconds. If the elapsed time is longer than 3 seconds, the process proceeds to step S230. If the elapsed time is shorter than 3 seconds, the process returns to step S221.

According to the second hill mode, the operation of the magnetic valve 120 is released after 3 seconds from the release of the brake pedal. As a result, the commercial vehicle is kept in a hill-free state before the driver releases the brake pedal and then advances or takes other actions. It is a matter of course that the time interval of 3 seconds is waiting for the judgment of the driver, and the time interval may be changed according to the setting.

3 is a view showing a result of using the anti-jam device 100 for a commercial vehicle according to an embodiment of the present invention.

3 (a) shows a state in which the commercial vehicle has stopped at the hill (upper end) and an indication (lower end) of the display unit 150. [ When the commercial vehicle stops at the hill and satisfies the above-described operating conditions, the magnetic valve 120 operates to operate the brake. The display unit 150 can visually indicate that the brake is being operated by the anti-jamming device 100 of the commercial vehicle (lower left), and displays the number of revolutions per minute that can generate a torque that the commercial vehicle is not pushed by the hill Can be displayed (bottom right). As shown in FIG. 3A, the display unit 150 can simultaneously display a visual indication that the brake is being operated and a display of the number of revolutions per minute adjacent to each other.

3 (b) shows that the commercial vehicle is about to start from the hill. The driver is accelerating by taking his foot off the brake pedal and stepping on the accelerator pedal. In the commercial vehicle, the magnetic valve 120 is operated by the brake, so that the commercial vehicle is kept in a stopped state without being pushed by the hill. 3 (a), the display unit 150 can visually indicate that the brake is being operated by the anti-jamming device 100 of the commercial vehicle (lower left), and generates a torque that the commercial vehicle is not pushed off the hill The number of revolutions per minute that can be displayed (bottom right).

Fig. 3C shows a state in which the commercial vehicle advances with sufficient torque to the extent that it is not pushed off the hill. The operation of the anti-jamming device 100 of the commercial vehicle is released, and the operation display portion on the lower left side of the display portion 150 is turned off. The display unit 150 can also release the visual display of the operation of the magnetic valve and can also display the number of revolutions per minute information display.
