BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an anti-jam device for a commercial vehicle and a method thereof.
As electronic devices applied to vehicles are developed, various vehicle assistant technologies are being developed.
The Hill Start Assist system is a device that electronically controls the brakes temporarily so that the vehicle does not stop downhill when the vehicle stops at the hill.
Such a hill anti-skid device is mainly applied to a passenger car, but a commercial vehicle is more necessary. Large-sized vehicles such as commercial vehicles are more massive than passenger cars, so cars are likely to be pushed backward on the hill and are likely to lead to major accidents.
On the other hand, a commercial vehicle must be ready to be pushed off the hill to get off the hill. In addition, the driver needs to check whether the hill anti-skid device operates. This is because the hill anti-skid device must start in a more careful manner than when the hill anti-skid device does not operate due to a failure or the like.
Korean Patent Laid-Open No. 10-2011-0027885 is a prior art related to a hill anti-skid device. The present invention relates to a technique for comparing a pressure of a brake master cylinder with a current tilt prevention pressure against a vehicle stopped on a ramp to prevent hill climbing according to a comparison result.
It is an object of the present invention to provide an anti-jamming device for a commercial vehicle that prevents the jamming of a commercial vehicle and provides relevant information to a driver in the event that a commercial vehicle such as a hill can be pushed.

It is possible to provide an anti-skid device.
Preferably, the information collecting unit further collects information about whether or not to wait for an excel pedal, and when the waiting state of the excel pedal continues for a predetermined time or longer after the operation of the brake pedal is released, And the operation of releasing the operation is canceled.
Preferably, the operation of the magnetic valve is started when the torque value is less than a predetermined value.
Preferably, the control unit further includes a display unit for displaying information provided from the control unit, wherein the control unit provides the display unit with the number-of-revolutions per minute capable of generating a torque equal to or higher than the predetermined value in the operating state of the magnetic valve And a stopper for stopping the operation of the commercial vehicle.
A method for preventing the anti-jamming device of a commercial vehicle including an information collecting unit, a magnetic valve, a control unit, and a display unit from preventing the jamming of a commercial vehicle, comprising the steps of: collecting information about whether the brake pedal of the commercial vehicle operates; Collecting information on whether the gear of the commercial vehicle is neutral or not; The information collecting unit collecting speed information of the commercial vehicle; The information collecting unit collecting information on the torque value of the commercial vehicle; Operating the magnetic valve when the brake pedal is operated and the gear is not neutral and the speed is lower than a predetermined speed; Providing the display unit with the number-of-rotations per minute information that the control unit can generate a torque equal to or greater than a predetermined value; The display unit visually displaying that the magnetic valve is operating and displaying the rotation speed information per minute adjacent to the display; Releasing the operation of the brake pedal when the magnetic valve is in operation and releasing the operation of the magnetic valve when the torque value is equal to or greater than a predetermined value; And the display unit releases the visual display of the operation of the magnetic valve and the display of the revolutions per minute information

Referring to FIG. 2, in step S200, the
The operating condition is a condition for the
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
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
