For example, when the brake pedal is stepped on the ramp, the magnetic valve 410 can be operated immediately. For example, when the brake pedal is released and a certain amount of torque is generated, the drive of the magnetic valve 410 may be released.

The information collecting unit 110 provides the collected information to the anti-skid control unit 120.

The anti-skid control unit 120 controls the magnetic valve 410 according to the information provided by the information collecting unit 110.

The first switch 130 determines whether the ramp-preventing module 100 is operated.

The lining wear sensor 510 is disposed adjacent to the wheel of the commercial vehicle to sense wear of the lining pad of the wheel of the commercial vehicle.

The abrasion state of the commercial vehicle may be provided as a voltage value measured by the lining wear sensor 510. [ For example, the lining wear sensor 510 may measure the lining (wear) state of the wheel to provide a voltage value between 0 and 5 volts. However, if a voltage value of less than 0.5 V or more than 4.5 V is provided, the controller of the brake module 200 may turn on the warning lamp through the display unit 600. This means that the remaining amount of the lining pad is 0%.

The operation part 400 interlocked with the brake module 200 includes a suspension electronic control unit 430 and an air suspension 440.

The second switch 220 is for controlling the suspension electronic control unit.

The second switch 220 includes a plurality of switches, and each of the switches may correspond to each function.

The controller of the brake module 200 receives the signal of the second switch 220 and transmits the signal to the suspension electronic control unit.

For example, if one of the second switches is operated when five pairs of wheels of a commercial vehicle are desired to be dropped from the ground without using two pairs of them, the control module of the brake module 200 controls the suspension electronic control unit 430, And the suspension electronic control unit 430 can control the air suspension 440 to lift the two wheels from the ground.

The control module of the brake module 200 may provide a function of allowing a part of the vehicle body of the commercial vehicle to move up and down in accordance with the application.

The connection unit 230 serves to connect the lining wear sensor 510 and the control unit of the brake module 200.

The connection unit 230 may be composed of eight channels, of which only six channels may be used, or all eight channels may be used. Which may depend on the number of lining wear sensors 510 disposed on the wheels.

The rotor and the stator can be constructed by combining two mechanisms with different wing shapes, and they support the braking of the commercial vehicle under the resistance by the oil.

7 is a flowchart illustrating a method of controlling an integrated module relating to a brake of a commercial vehicle according to an embodiment of the present invention.

Each step in FIG. 7 can be performed through the brake module 200 control unit according to an embodiment of the present invention.

Referring to FIG. 7, in step S701, the controller of the brake module 200 receives the sensor value.

The sensor value may be provided as a value measured by the lining wear sensor 510 of the sensor unit 500 described above. The sensor value can be received periodically. For example, one sensor value per 10ms can be received.

In step S703, the controller of the brake module 200 samples the sensor value. Sampling values may fluctuate at normal values due to internal or external variables, so it may be desirable to average a certain number of values.

In step S705, the control module of the brake module 200 determines whether or not there is a display request. If there is a display request, the process proceeds to step S709; otherwise, the process proceeds to step S707.

The display request may be input through a display request button through a user interface or the like, or may be input upon start-up of a commercial vehicle or upon detection of operation of the brake module 200.

The indication request is a request entered to indicate the remaining amount of the lining pad immediately, even if the sampling number of sensor values is insufficient.

In step S707, the controller of the brake module 200 determines whether the sampling number is equal to the preset value.

In one embodiment of the present invention, the controller of the brake module 200 determines whether the number of samplings is 128. If the number of sampled sensor values is 128, the process proceeds to step S709. If the number of sampled sensor values is less than 128, the process returns to step S703, and steps S703 to S707 are repeated.

In step S709, the controller of the brake module 200 extracts an average value.

The average value can be an arithmetic average of the 128 sensor values sampled or the sensor values of less than 128 samples. In this case, it is also possible to remove the sampling value which deviates by more than a predetermined value from the average value, and then take the average value again.

In step S711, the controller of the brake module 200 displays the remaining amount of the lining pad through the display unit 600. [

Displaying the remaining amount of the lining pad informs the replacement point of the lining pad and can provide convenience to the operation of the commercial vehicle.
