The present invention relates to a non-slip device and a method for preventing a shift of a semi-automatic transmission vehicle to prevent the vehicle having a semi-automatic transmission from slipping when shifting on a slope.

Vehicles equipped with semi-automatic transmissions are provided with shift detection sensors on the shift lever instead of the shift pedal, and are shifted while engaging and disengaging the clutch under the control of the microcomputer according to the detection signals of the shift detection sensors. .

In the case of shifting on the ramp, for example, when the vehicle shifts at a slow speed on the ramp or starts from a stopped state, the vehicle slides along the ramp, so the vehicle shifts at a high speed on the ramp. It should not slip along.

However, a vehicle having a conventional semi-automatic transmission has a shift operation at a constant speed regardless of a slope.

Therefore, when the vehicle is shifted on the slope, there is a problem such that a safety accident occurs when the vehicle slips and collides with another vehicle positioned at the bottom of the slope, as well as anxiety to the driver.

Accordingly, an object of the present invention is to provide an anti-slip device and a prevention method for shifting a semi-automatic shifting vehicle to prevent the vehicle from sliding along the ramp by performing the shifting operation at a high speed when shifting on the ramp.

The present invention for achieving this object is provided with a horizontal sensor to detect whether the slope, and when there is a shift request in the state in which the horizontal sensor detects the slope to determine the current speed of the vehicle, the determined speed of the vehicle in advance When the speed is less than the set speed is characterized in that the speed is set quickly to change the speed.

Therefore, according to the present invention, when the vehicle shifts on the slope, the vehicle does not slide backwards on the slope, thereby preventing the occurrence of a safety accident.

Hereinafter, with reference to the accompanying drawings will be described in detail a non-slip device and a method of preventing the shift of the semi-automatic vehicle according to the present invention.

1 is a circuit diagram showing a non-slip device of the present invention. As shown therein, a GPS (Gear Position Sensor) 1 installed in a storage box to detect a current shift position and a Throttle Position Sensor (TPS) 2 installed at a throttle valve to detect the engine speed are shown. And a force sensing switch (FSS) 3 mounted on the gear lever to determine the driver's shifting intention, a horizontal sensor 4 detecting whether the road surface is a slope, the GPS 1, the TPS 2, A microcomputer 5 for controlling shifting and running of the vehicle according to the output signals of the FSS 3 and the horizontal sensor 4, and a clutch drive control unit for controlling the driving of the clutch according to the output signal of the microcomputer 5; (6) and a clutch drive unit 7 for shifting by driving the clutch under the control of the clutch drive control unit 6.

FIG. 2 is an enlarged cross-sectional view showing the configuration of the horizontal sensor 4 of FIG. 1, in which the balls 44 are placed in the cylindrical guide tube 41 with springs 42 and 43 on both sides. And the ball 44 is connected to the variable resistor 46 through the connecting lever 45 so that the variable resistor 46 is variable as the ball 44 is moved left and right according to the inclination of the guide tube 41. .

In the anti-skid device of the present invention configured as described above, the GPS 1 detects whether the gear of the gearbox is currently connected to the microcomputer 45 while driving the vehicle, and the TPS 2 detects the engine speed. To the microcomputer 5, and the FSS 3 detects whether the driver shifts and inputs it to the microcomputer 5, and the horizontal sensor 4 changes the variable resistor 46 according to the movement of the ball 44 during driving. While being variable, the slope is determined and input to the microcomputer 5.

Then, the microprocessor 5 determines the gear state of the gearbox by the output signal of the GPS 1 and controls the running of the vehicle while determining the engine speed by the output signal of the TPS 2.

Then, the horizontal sensor 4 determines the slope as the variable resistor 46 is variable as the ball 44 moves while the vehicle is traveling, and the microcomputer 5 uses the output signal of the horizontal sensor 4 to determine the current slope. It determines whether you are driving.

When driving on the slope, the microcomputer 5 detects whether the driver shifts with the signal of the FSS 3, and judges the traveling speed of the vehicle by the detection signals of the GPS 1 and the TPS 2 when the shift is requested, and is less than or equal to the preset speed. In this case, set the shift time quickly, and if it is over the set speed, set the shift time to normal.

When the shift time is set as described above, the microcomputer 5 outputs a control signal corresponding to the shift time set by the clutch drive control unit 6, and the clutch drive control unit 6 transmits the clutch drive unit 7 according to the output control signal. To control the shifting operation.

On the other hand, Figure 3 is a signal flow diagram showing a slip prevention method of the present invention. As shown in FIG. 4, the microcomputer 5 determines whether the vehicle is traveling uphill or downhill using the output signal of the horizontal sensor 4, and the driver uses the signal of the FSS 3 when driving uphill or downhill. Determines if the shift is required.

At this time, when the driver requests the shift, the driving speed of the vehicle is determined by signals of the GPS (1) and the TPS (2), and the shift time is quickly set when the speed is less than or equal to the preset speed. Set to to perform the shifting operation.

Here, the set speeds according to the uphill and downhill are set differently, for example, the speed of the vehicle is set close to 0Km on the uphill road, and set to the optimum value after the test on the downhill road, about 0 ~ 5Km Set it.

As described in detail above, the present invention prevents the vehicle from slipping on the slope by changing the shift time according to the traveling speed of the vehicle when the vehicle shifts while driving on the slope, thereby preventing the occurrence of a safety accident. The driver can drive the vehicle more comfortably.
