Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing the structure of a steering wheel for a disabled vehicle according to the present invention.

As shown in FIG. 1, the lever 200 is mounted to a predetermined position of the handle 100, and the first to fourth switches are switched to the left and right rotation and the forward and backward rotation of the lever 200 based on the front of the driver. The handle contacts 110-140 and the first to fourth lever contacts 210-240 are installed.

The first to fourth handle contacts 110 to 140 are connected to the control unit 300, and the control unit 300 is a signal and a brake signal applied from the first to fourth handle contacts 110 to 140. Analyzes the delay time and selects the gear shift (range) and controls the blinking of the turn signal.

In the first to fourth handle contacts 110-140, the first and second handle contacts 110-120 are left and rear selection contacts of the turn signal lamp, and the third and fourth handle contacts 130-140 are gears. Selective contact for upshift and downshift for shifting.

The first to fourth lever contacts 210 to 240 are in contact with the first to fourth handle contacts 110 to 140 by a lever operation of a driver, and the first and second lever contacts 210 to 220 are respectively By contacting the first and second handle contacts 110-120 according to the left and right manipulation of the lever 200, a signal for selecting a turn signal is output, and the third and fourth lever contacts 230-240 are In response to the front and rear operation of the lever 200, the third and fourth handle contacts 130 to 140 are contacted to output signals for selecting an upshift and a downshift for the gear shift.

The controller 300 analyzes the contact between the first to second handle contacts 110-120 and the first to second burr contacts 210-220 to control the blinking of the left indicator light or the right indicator light.

In addition, the controller 300 analyzes the contact time between the third to fourth handle contacts 130 to 140 and the third to fourth lever contacts 230 to 240, and the delay time of the signal and the contact contact of the brake pedal. Controls the selection of another gear shift in the current gear shift.

Referring to the operation of controlling the selection of the gear shift stage (range) and the flashing of the direction indicator in the present invention including the function as described above is as follows.

Referring to FIG. 3, an operation of selecting a gear shift stage will be described with reference to FIG. 3. In the following description, the symbol “-” denotes a contact between the third handle contact 130 and the third lever contact 230. The sign "+" means contact between the fourth handle contact 140 and the fourth lever contact 240.

In the state in which the engine starts to be kept on (S101), the controller 300 checks the current gear shift stage (range) selected by the shift lever (S102), and selects the "P" range which is the current parking gear shift stage. It is determined whether there is a state (S103).

When the current gear shift stage is in the state of selecting the "P" range which is the parking shift stage, detection of contact between the third to fourth handle contacts 130-140 and the third to fourth lever contacts 230-240 is performed. An input value such as a signal, a delay time, a signal of whether the brake pedal is operated or not is analyzed (S104), and it is determined whether the input value is a condition of "-, 2, 0" (S105).

The meaning of "-, 2, 0" means that the third handle contact point 130 and the third lever contact point 230 are in contact with each other, and a delay time for contacting the contact point is set to 2 seconds or more. It means the state of stepping on (0).

If the delay time for the contact of the contact is within 2 seconds of the set time, the detection signal is determined to be a malfunction of the driver with a disability, and the detection signal is ignored.

If the condition of "-, 2, 0" is satisfied in the judgment of S105, since the current gear shift stage is no longer able to move to the lower stage from the "P" range state, a voice warning message thereof is output. And, for example, if you want to start, pull the lever toward the body outputs a guide message (S107).

If it is determined in step S105 that the condition of "-, 2, 0" is not satisfied, it is determined whether the condition of "+, 2, 0" is satisfied (S106).

If it is determined in S106 that the condition of "+, 2, 0" is not satisfied, the above-described routine of S107 is performed. If the condition of "+, 2, 0" is satisfied, the controller 300 drives the actuator (not shown). To control the shift of the "R" range (S108).

The meaning of "+, 2, 0" means that the fourth handle contact 140 and the fourth lever contact 240 are in contact with each other, and a delay time for contacting the contact is over 2 seconds, which is a set time. It means the step (0) being stepped on.

If the brake pedal is not pressed, "X" is used.

 As described above, the input values are continuously analyzed in the state of controlling the shift of the “R” range to control the contact of the third to fourth handle contacts 130 to 140 and the third to fourth lever contacts 230 to 240. An input value such as a detection signal, a delay time, and a signal of whether the brake pedal is operated is analyzed (S109), and it is determined whether the input value is a condition of "+, 2, 0" (S110).

If the condition of "+, 2, 0" is satisfied in the determination of S110, the control unit 300 controls the driving of an actuator (not shown) to allow shifting of the "N" range (S111).

In addition, as described above, the input values are continuously analyzed while the shift of the “N” range is controlled to contact the third to fourth handle contacts 130 to 140 and the third to fourth lever contacts 230 to 240. An input value such as a detection signal, a delay time, and a signal of whether the brake pedal is operated is analyzed (S112), and it is determined whether the input value is a condition of "+, 2, 0" (S113).

When the condition of "+, 2, 0" is satisfied in the determination of S113, the control unit 300 controls the driving of an actuator (not shown) to allow shifting of the "D" range (S114).

As described above, it is determined whether the input signal detected while driving by selecting the "D" range is a condition of "+, 0.5, X" (S115), and if the condition of "+, 0.5, X" is satisfied, "D". The upshift shifting of the " 1 &quot; stage is controlled in the current shift stage of the range (S116).

However, if the condition of "+, 0.5, X" is not satisfied in the determination of S115, it is determined whether the condition of "-, 0.5, X" is satisfied (S121), and if the condition of "-, 0.5, X" is satisfied, The downshift shifting of the " 1 " stage is controlled in the current shift stage of the " D " range (S122).

If the condition "-, 0.5, X" is not satisfied in the determination of S121, the current shift stage selected in the "D" range is maintained (S123).

The meaning of "+, 0.5, X" means that the fourth handle contact 140 and the fourth lever contact 240 are in contact with each other, a delay time for contacting is 0.5 seconds, and a driving state in which the brake pedal is not stepped on. And, "-, 0.5, X" means that the third handle contact 130 and the third lever contact 230 is in contact, the delay time for the contact is 0.5 seconds, the driving state is not stepped on the brake pedal it means.

Further, in the determination of S110, if it is not a condition of "+, 2, 0", it is determined whether it is a condition of "-, 2, 0" (S117), and if it is not a condition of "-, 2, 0", the current "R" If the selection of the range is maintained (S123) and the condition of "-, 2, 0" is satisfied, an actuator (not shown) is controlled to shift the range from the "R" range to the "P" range (S118).

In addition, if the condition of "+, 2, 0" is not satisfied in the determination of S113, it is determined whether the condition of "-, 2, 0" is satisfied (S119). Maintain the selection of the "N" range of (S123), and if the condition of "-, 2, 0" is satisfied, an actuator (not shown) is controlled to shift from the "N" range to the "R" range (S120). ).

As described above, if the current gear shift selects the "P" range while the engine is being started on, pull the lever 200 toward the driver's body while pressing the brake pedal (0). When the four-handle contact 140 is in contact with the fourth lever contact 240 and the delay time for the contact is maintained for 2 seconds, the shift from the "P" range to the "R" range proceeds. Selection to the D "range is made.

Further, when the current gear shift stage selects the "D" range, the user presses the brake pedal (0) and pushes the lever 200 outward to move the third handle contact 130 and the third lever contact 230. When the contact is made and the delay time for the contact is maintained for 2 seconds, the shift of the "N" range is performed from the "D" range, and the selection of the "R" range or the "P" range is performed through this operation.

In addition, the third handle contact 130 and the third lever contact 230 are brought into contact with each other by pushing the lever 200 outward without pressing the brake pedal in the state where the “D” range is selected and traveling (X). If the delay time is maintained for 0.5 seconds, the "1" stage downshift shift is performed at the current drive shift stage selected in the "D" range.

In addition, the fourth handle contact 140 and the fourth lever contact 240 are brought into contact with each other by pulling the lever 200 toward the body without pressing the brake pedal in the state of driving by selecting the “D” range (X). If the delay time is maintained for 0.5 seconds, the "1" stage upshift shift is performed at the current drive shift stage selected in the "D" range.

As a second embodiment, an operation of controlling the blinking of the direction indicator will be described with reference to FIG. 4 as follows.

In a state in which a predetermined shift stage is engaged and traveling by the operation of the above-described first embodiment (S201), the controller 300 controls the first to second handle contacts 110-120 and the first to second lever contacts 210-. By analyzing the input value according to the contact of the 220 (S203), it is determined whether the input signal value is detected by the condition of "-", preferably the contact of the second handle contact 120 and the second lever contact 220. (S203).

When it is detected in S203 that the contact of the second handle contact point 120 and the second lever contact point 220 is performed, the controller 300 controls the blinking of the left direction indicator light (S204).

However, in the determination of the 203, if the second handle contact 120 and the second lever contact 220 are not in contact, the input signal value is "+", preferably, the first handle contact 110 and the first It is determined whether the contact of the lever contact 210 is detected (S205).

When it is determined in S105 that the first handle contact point 110 and the first lever contact point 210 are in contact with each other, the control unit 300 controls the blinking of the right turn indicator (S206) and the first handle contact point 110. If the first lever contact 210 is not in contact with the turn signal maintains an off state (S207).

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

As described above, the present invention is equipped with a lever capable of operating a gear shift and a direction indicator on a steering wheel (steering wheel) of a disabled vehicle, thereby providing stability and reliability in driving a vehicle of a disabled driver who is inconvenient to use both hands.
