The present invention relates to an automatic shift control apparatus for parking a ramp of a vehicle, and more particularly, to an automatic shift control apparatus for parking a ramp of a vehicle in which a gear is automatically shifted to one step or backward when the vehicle is parked on an inclined place.

In general, when parking a vehicle, the parking brake is used to maintain the parking state of the vehicle. Sometimes, the parking brake is released and the vehicle is moved.In the winter, when the parking brake is filled, the parking brake shoe and drum are frozen. Since the brake shoe is worn after driving the vehicle in such a state, a problem that the vehicle is pushed when using the parking brake occurs, and when the vehicle is parked on the inclined road, the parked vehicle is moved.

This problem can be solved somewhat by parking after the transmission gear is shifted to the first gear or the reverse gear after pulling the parking brake.

This is because the wheels cannot be rolled easily because the differential gears, gearbox, engine crankshaft and pistons must be driven in order for the wheels to be rolled with the starter off and the transmission gear shifted to the 1st or reverse direction. In some cases, the jungle of vehicles on the hills could be eliminated to some extent.

However, when the transmission was not shifted to the lower or reverse state due to the driver's carelessness, the vehicle was pushed as described above, resulting in a safety accident.

The present invention has been made to solve such a conventional problem, the gear is automatically shifted to the first stage when the vehicle parking on the uphill, the gear is automatically shifted to the reverse when the vehicle parking on the downhill An object of the present invention is to provide an automatic shift control device when parking on a slope.

In order to achieve the above object, the present invention provides a timer switch that is cut off after supplying a predetermined time current when the key holder is switched off and the parking brake switch is turned on after the vehicle parking, the inclination angle, the engine speed, A sensor unit for detecting an acceleration state and a position of a shift lever, a controller which receives each data inputted from the sensor unit, and compares the preset data with a preset data and outputs a corresponding control signal; and a left / right rotation by a control signal of the controller And a first motor to be shifted, a second motor to be moved forward and backward by the control signal of the controller, and shifting means for shifting by driving the first and second motors.

Hereinafter, with reference to the accompanying drawings an embodiment of the automatic shift control device when parking the slope of the present invention will be described in detail as follows.

1 is a configuration diagram of the present invention, a timer switch 10 which is cut off after supplying a predetermined time current when the key holder is switched off and the parking brake switch is turned on after the vehicle parking, and an inclination angle when the timer switch 10 is operated. The controller 20 detects the engine speed, the acceleration state, and the position of the shift lever, and receives each data input from the sensor unit 20 and compares the preset data with the preset data to output a corresponding control signal. 30, the first motor 40 for rotating the first pitch rail gear 64 left and right by the control signal of the controller 30, and the second pitch by the control signal of the controller 30. A second motor 50 for forwarding and reversing the rail gear 65 and a general shifting means 60 for shifting by driving the first and second motors 40 and 50 are provided.

Here, the shift means 60 is a shift lever 61 for shifting as shown in FIG. 2 and a shift lever shaft 62 for transmitting power to the fork shaft according to the adjustment of the shift lever 61. ) And a transmission 63 configured to shift by the shift lever 61, and the like.

At this time, the second pitch rail gear 65 that is forward and backward by the second motor 50 is coupled to the end of the shift lever shaft 62 having one end coupled to the fork shaft in the transmission 63, The first pitch rail gear 64 which is moved to the left and right by the first motor 40 is coupled to the bottom of the second pitch rail gear 65 so as to move the shift lever shaft 62 to the left and right. do.

The arrow direction shown in FIG. 2 above or below is represented by a dashed arrow on the forward side and the right side, and is represented by a solid arrow on the reverse side and the left side. That is, the right shift of the shift lever 61 and the first pitch rail gear 64 is represented by a broken arrow, and the left shift is represented by a solid arrow, and the shift lever 61 and the second pitch rail gear 65 are advanced. Movement is represented by dashed arrows and backward movement is represented by solid arrows.

According to the present invention configured as described above, when the driver turns off the key switch of the key holder and lifts the parking brake upward to turn on the parking brake switch, the current is generated by the timer switch 10 for a predetermined time (for example, 15 seconds). It is cut off after being supplied to the sensor unit 20.

Therefore, the sensor unit 20 detects the state of the current vehicle by each sensor for a predetermined time while the current is supplied.

That is, the inclination angle sensor S1 detects the degree of inclination in the parking state of the vehicle, and the engine speed sensor S2 detects the engine speed. The engine speed becomes zero when the vehicle is parked. . And the acceleration degree is detected by the acceleration sensor S3. Similarly, the acceleration detected by the acceleration sensor S3 becomes zero.

In addition, the shift lever position detection sensor (S4) is to detect the position of the shift lever 61, the position of the shift lever 61 at the time of parking is neutral so that the data sensed by each sensor is controller 30 The controller 30 compares the input data with the preset data.

Here, the shift lever position sensor (S4) is a light emitting sensor (L1) (L2) is provided in the front and rear of the lower end of the shift lever 61, as shown in Figure 3, the light receiving sensor (R1-) in each shift. R6) is installed, and when the shift lever 61 is shifted to each shifting position, the light of the light emitting sensors L1 and L2 is received by the corresponding sensor among the light receiving sensors R1-R6 to detect the light. When the shift lever 61 is positioned in the neutral position, the light of the light emitting sensors L1 and L2 is not received by any of the light receiving sensors R1 to R6, so that the light is not detected. Received the detection state of the shift lever position sensor (S4) at 30 to recognize the current shift position of the vehicle.

Therefore, when it is determined by the comparison judgment of the controller 30 that the current vehicle is parked in the inclined position and the shift lever 61 is in a neutral state, the controller 30 controls the shift means 60 to automatically shift the speed. To be done.

That is, when it is detected that the vehicle is parked on an uphill road by the inclination angle sensor S1, the controller 30 first controls the first motor 40 so that the first motor 40 is driven to drive the first pitch rail. Adjustment is made so that the gear 64 coincides with the first gear, and then the controller 30 controls the second motor 50 so that the second motor 50 is driven so that the second pitch rail gear 65 is forward. By shifting to the shift lever shaft 62 is shifted to the first gear.

That is, in order to shift to the first stage in the state in which the shift lever 61 is neutral, as shown in FIG. 2, the shift lever 61 is shifted to the left and then moved forward to select the gear. Since the controller 30 operates the first motor 40 to move the first pitch rail gear 64 in the direction of the arrow shown in the drawing (left), the shift lever shaft 62 The shifting lever 61 is shifted to the left to be shifted, and in this state, the controller 30 operates the second motor 50 to move the second pitch rail gear 65 to the arrow shown in the drawing. In the forward direction, the shift lever shaft 62 moved to the left by the first motor 40 moves forward, and the shift fork inside the transmission 63 shifts the gear to the first stage. In this way, the low speed shift of the transmission 63 is achieved automatically. Which will be.

In this way, the shift lever 61 and the shift lever shaft 62 are moved left and right by the first and second pitch rail gears 64 and 65 operated by the first and second motors 40 and 50. Then, one end of the shift lever shaft 62 moves the shift fork shaft inside the transmission 63, and the sliding gear is bitten at low speed with the gear of the sub-shaft or at idle or retracted by the movement of the shift fork shaft. The gear of the transmission 63 may be shifted.

Since the gear shift relation inside the transmission 63 is a well-known technique, a detailed description thereof will be omitted.

In this way, the gear of the transmission 63 can be shifted to the first stage because the shift can be performed without the clutch operation in the engine stop state (starting off).

Here, when the first motor 40 is driven left and right, the second motor 50 is not driven but moves together. When the second motor 50 is driven forward and backward, the first motor 40 is not driven. But go together.

On the other hand, when it is detected that the vehicle is parked on the downhill by the inclination angle sensor (S1), the controller 30 controls the first motor 40 for adjusting the dust, left and right, so that the first motor 40 is Adjustment is made so that the first pitch rail gear 64 is aligned with the reverse gear side, and then the second motor 50 is driven by controlling the second motor 50 in the controller 30 so that the second pitch rail gear is driven. As the 65 moves backward, the shift lever shaft 62 is moved to shift to the reverse gear.

That is, in order to shift backward in the state in which the shift lever 61 is neutral, as shown in FIG. 2, the shift lever 61 is moved rearward (arrow direction) and then moved to the right (arrow direction), Since the gear 30 is shifted back to shift backward, the controller 30 operates the first motor 40 in a neutral state to move the first pitch rail gear 54 in the direction of the arrow shown in the drawing (right side). When shifted to), the shift lever 61 coupled to the shift lever shaft 62 is shifted to the right to be shifted. In this state, the controller 30 operates the second motor 50. When the second pitch rail gear 65 is reversed in the arrow direction (rear) shown in the drawing, the shift lever shaft 62 already moved to the right by the first motor 40 is moved backward. Shift forks inside the gearbox 63 are geared And the shift to the reverse, so that the backward shift of the transmission 63 that will be automatic.

Thereafter, when the driver opens the door to drive the vehicle, the door switch SW1 is turned off, so that the controller 30 detects this and outputs a control signal opposite to the case where the gear is shifted to the first gear or the reverse gear. The first motor 40 is driven, and then the second motor 50 is driven to move the shift lever shaft 62 so that the gear is shifted to a neutral position. Accordingly, the driver can drive the vehicle in a state where the gear is neutral. It will be possible.

For example, when the door switch SW1 is turned off while the gear is shifted to the first stage, the controller 30 operates the second motor 50 to cause the second pitch rail gear 65 to reverse. The first motor 40 is operated to move the first pitch rail gear 64 to the right so that the shift lever 61 is moved to the neutral position.

In this way, when the vehicle parks on an uphill or downhill road, the transmission 63 is automatically shifted to the first gear or the reverse gear by the controller 30, so that the parking brake is pushed down by giving resistance to the rolling clouds. The vehicle is prevented from rolling.

That is, in order to rotate the wheel while the transmission 63 is automatically shifted to the first gear or the reverse gear, the flywheel connected by the differential gear, the gearbox and the gear and the clutch inside the propulsion shaft and the transmission 63 are driven. Since the crankshafts connected to the pistons had to be driven, the clouds on the wheels of the cars parked on the hills were not easy.

As described above, the present invention detects the degree of inclination by the inclination angle sensor (S1) when the vehicle is parked at an inclined place, and automatically shifts to a single gear when parking on an uphill road, and automatically reverses when parking on a downhill road. As a result, the driver does not need to manually shift the gear to the first or the reverse as in the prior art, and the vehicle is not pushed because the gear is shifted to the first or the reverse even when the parking brake is released. do.
