The pushing member 84 and the locking member 86 are installed through the pressing member, and the pushing member 92 and the locking member 94 are installed at both sides of the other electromagnet member 46 through the elastic members 88 and 90. .

The pushing member and the locking member facing away from the electromagnet members are manufactured to be pushed outward by the magnetic force while having the same polarity as the polarity when the electromagnet member releases the magnetic force.

The pushing members have the same length and are spaced apart from each other at the free end side and are installed so that the member 96 can swing left and right about the center hinge portion. In the case of change, the elastic members 98 and 100 are installed on the left and right about the hinge point of the central portion so that the original position can be returned to the original position.

And below both side ends of the seesaw member 96, a switch 102 for rotating the drive motor described later and a switch 104 for rotating in the forward direction are located within the swing range of the seesaw member.

In a position corresponding to the locking members 54, 62, 70, 78, 86, and 94, the rack member 106 is installed to linearly move along the guide rail 108 installed in the vehicle body.

A plurality of teeth are formed on one side of the rack member 106, and the teeth are driven by a drive pinion 112 that rotates in the forward and reverse directions by the drive motor 110, and a control cable of the transmission. The control gear 116 to which one end of the 114 is connected is installed to receive a rotational force through the idle gear 118.

The locking member 70 positioned above the electromagnet member 40 corresponding to the neutral range is capable of lifting up and down along the guide member 120, and the contact member 120 is installed on the guide member 120. It is configured to enable the energization in the position in contact with the locking member (70).

The contact point 122 is configured to be connected to an input terminal of a normal electronic control unit (ECU) so that a signal can be input while the contact is turned on, and another input terminal of the electronic control unit (ECU) is connected to an input terminal of the selector lever 2. An inhibitor switch 124 for detecting a position and a garage sensor 126 for detecting whether the vehicle is in an inclined position are connected.

The braking electromagnet member 128 is connected to the output end of the electronic control unit ECU to receive a current, and the pusher 130 is positioned in a posture corresponding to the electromagnet member.

The head of the pusher may be a permanent magnet 132 having the same polarity as the polarity when the electromagnet member 128 forms a magnetic force.

And the electromagnet member 128 and the permanent magnet 132 is provided in the direction having a pulling force with each other by the elastic member 134.

A rack gear 136 is formed in the pusher 130, which is gear-coupled with the pinion 140 integrally formed at the hinge portion of the brake pedal 138.

In the shift stage control apparatus of the present invention, the selector lever 2 is first moved to the D range, and the current switch is applied to the electromagnet member 42 while the first switch 24 for selecting the traveling range is turned on. Make the member magnetic.

By the magnetic force, the pushing member 76 having the same polarity as the electromagnet member 42 is moved downward in the view, and the locking member 78 is moved upward in the view.

In this series of operations, the seesaw member 96 is inclined to the right about the center hinge point to turn on the switch 104 by the pushing member 76.

The switch 104 has a function of performing a switch connection for rotating the driving motor 110 in the forward direction. The switch 104 has a state in which the driving motor can be rotated in the forward direction. When power is applied to the driving motor 110 while the switch 26 is turned on, the driving motor starts to rotate in the forward direction.

Therefore, since the pinion 112 installed on the drive shaft of the drive motor 110 starts to rotate, the rack member 106 coupled to the gear starts moving to the left side in the drawing.

At this time, the control gear 116 is rotated through the idle gear 118, so that the control cable 114 is pulled, so that the gear shift stage is selected as the driving range.

In this way, the driver rotates the control gear 116 while the rack member 106 moves by moving the selector lever 2, so that the control cable 114 can be pulled to select the shift stage.

This action is the same as the selector lever 2 moves to any shift stage, so the description of the other shift stage selection operation is omitted.

When the selector lever 2 is shifted to the neutral (N) range when such a shift stage action is made, the rack member 106 moves to the right as seen in the drawing, and the locking member 70 is operated as described above. ) Is inserted into the locking groove H formed in the rack member while being raised, the position of the selector lever is input to the electronic control unit by the inhibitor switch 124, and the vehicle attitude is inclined by the garage sensor 126. Is detected and input into the electronic control unit.

When such an action is performed, the locking member 70 is raised to turn on the contact 122 provided in the guide member 120, and at the same time, a signal is transmitted to the electronic control unit.

When such signals are input, the electronic control unit applies a current to the braking electromagnet member 128 to cause the member to exert a magnetic force.

When the electromagnet member 128 exhibits a magnetic force, the pusher 130 having the permanent magnet of the same polarity is pushed to the right as shown in the drawing, and this rack pusher is formed so that the rack gear 136 is formed. The pinion 140 rotates as the gear moves.

At this time, since the brake pedal 138 integrally formed with the pinion 140 and having the same hinge point rotates in the direction of the arrow shown in the drawing, the brake is performed while the driver is stepping on the brake pedal.

As described above, the shift stage control apparatus according to the present invention changes the range selection from the linear movement structure to the shifting direction in the selecting direction and the shifting direction so that the shift stage can be determined by the switch on / off operation. The shift stage selection can be prevented from being wrong, and the shift control unit can automatically perform braking in the neutral state, thereby reducing the physical fatigue of the driver, and in the neutral state on the ramp. The vehicle can be prevented from reversing.
