The operation will be described.
[Engine OFF control]
FIG. 5 is a flowchart showing a flow of processing of engine OFF control executed by the AT shifter controller and the idling stop controller of the first embodiment, and each step will be described below.
First, in step S11 of FIG. 5, it is determined whether or not the vehicle speed obtained from the input of the vehicle speed pulse 51 is zero and the information from the brake information 52 is in a brake-on state. If the condition is satisfied, the process proceeds to step S12. . If the condition is not satisfied, the process is terminated (in this case, it may be re-executed at a predetermined timing).

  In step S12, it is determined whether or not a predetermined time has elapsed since the condition is satisfied in step S11. If it has elapsed, the process proceeds to step S13, and if not, the process returns to step S12.

  In step S13, an engine OFF instruction signal is output from the idling stop controller 50b to the ECU 11, and the process proceeds to step S14.

  In step 14, it is determined whether or not the engine is OFF and the brake is ON. If the condition is satisfied, the process proceeds to step S15. If the condition is not satisfied, the process is terminated.

  In step S15, a signal for driving the motor 7 is output from the AT shifter controller 50a, and the shift is switched from the D range to the N range (stop state transition means).

[Engine ON control]
FIG. 6 is a flowchart showing a flow of processing of engine OFF control executed by the AT shifter controller and the idling stop controller of the first embodiment, and each step will be described below.
Next, in step S16 in FIG. 6, after the motor 7 is driven in step S15 in FIG. 5 and the shift is switched from the D range to the N range, the brake operation is released from the input of the brake information 53 in the idling stop controller 50b. It is determined whether or not it has been released. If not released, the process is terminated (in that case, it may be re-executed at a predetermined timing or the like).

  In step S17, a signal for driving the ABS 13 is output from the idling stop controller 50b to start brake support, and a signal for driving the cell motor 12 is output to restart the engine (engine start command means).

  In subsequent step S18, the AT shifter controller 50a outputs a signal for driving the motor 7 to forcibly switch the select lever 3 from the N range position to the D range position (state returning means).

  In a succeeding step S19, it is determined whether or not the accelerator is turned on. If the accelerator is turned on, the process proceeds to a step S20 to release the brake support by the ABS. Thus, the vehicle can be started by depressing the accelerator. If the accelerator is not turned on, the process returns to step S19.

[Assist action]
In the vehicular automatic transmission operating device according to the first embodiment, the motor 7 is assisted and driven according to the operation position from the position sensor 231. When the assist force is transmitted from the worm 71 to the worm wheel 23, the assist force is applied to the operating force transmission system of the select lever 3 and the output lever 8 that are coaxial with the shaft 21. Therefore, the shifting operation is performed with a light operation.

[Idle stop by simple operation]
In the first embodiment, the engine is stopped at an idle stop by the vehicle speed being zero and the brake being turned on. At this time, by driving a motor 7 provided in the middle of an operation transmission system from the select lever side to the automatic transmission 9, the select lever 3 when not operated is forcibly switched by an assist force.
In the first embodiment, since the range to be switched is the D range and the N range, the position gate 22 and the position pin 6 described in the above configuration do not interfere. Specifically, the D range and the N range are adjacent range positions, and the groove depth of the position gate 22 is the same groove depth.

Therefore, in the first embodiment, an automatic transmission operating device that does not provide a special configuration on the automatic transmission 9 side, provides an assist force, and enables manual range switching in the event of an abnormality is provided by a clutch or the like. A device that achieves both idle stop without disconnecting.
In addition, the range positions of the automatic transmission 9 and the select lever 3 are always consistent with each other, so that the driver does not feel uncomfortable and does not require special understanding.
Furthermore, with regard to this idle stop and vehicle re-start, only the brake operation and the accelerator operation are performed, which is a very simple operation, and the driver can travel in consideration of the environment by the idle stop without feeling the operation load. It becomes.

Explain the effect. The vehicle automatic transmission operating device according to the first embodiment has the effects listed below.
(1) The select lever 3 and the control lever 91 of the automatic transmission 9 are connected by a select operation force transmission system, and the select operation force transmission system is provided with a motor 7 for assisting the select operation force by the driver. The speed change operation device includes a position sensor 231 that detects the operation position of the select lever 3 and an AT shifter controller 50a that controls the motor 7 based on the operation position of the select lever 3. The AT shifter controller 50a is configured to stop and brake the engine. Since the processing of steps S11 to S15 by the AT shifter controller 50a that forcibly moves the select lever 3 from the D range position to the N range position in the operating state, operations related to engine stop and restart can be simplified. From stop to re-start at idling stop It is possible to shorten the.

  (2) In the above (1), after the brake is not operated, the controller 50 forces the processing of step S17 executed by the idling stop controller 50b that outputs a command to start the engine and the select lever 3 after the engine is started. Since the process of step S18 executed by the AT shifter controller 50a that moves from the N range position to the D range position is provided, the transition to the idle stop state without any special operation and the subsequent restart is performed only by the brake operation. Can do.

  (3) In the above (2), the idling stop controller 50b forcibly moves the select lever 3 from the N range position to the D range position by the process of step S18 executed by the AT shifter controller 50a after the brake is not operated. Since the command to perform the braking operation is output until the vehicle is moved, it is possible to prevent the driver from making an unplanned movement that causes the vehicle to move when the vehicle restarts due to the inclination of the road surface.

Further, in the vehicle automatic transmission operating device according to the first embodiment, after the idling stop operation, the vehicle can be started by simply releasing the brake without requiring a select lever operation or an engine restart operation. .
Therefore, it is possible to shorten the time until the vehicle restarts after the idling stop operation.

  Also, since the shift is moved instead of moving the mission, it is easy for the driver to recognize that the mission position has changed automatically.

The automatic transmission device for a vehicle according to the second embodiment is an example in which the engine is started in accordance with the switching operation to the D range when the driver leaves the idle stop and restarts.
Since the configuration is the same as that of the first embodiment, the description thereof is omitted.
The operation will be described.
The engine OFF control is the same as in the first embodiment.

[Engine ON control]
FIG. 7 is a flowchart showing a flow of processing of engine ON control executed by the AT shifter controller and the idling stop controller. Each step will be described below.

  In step S31, after the motor 7 is driven in step S15 in FIG. 5 and the shift is switched from the D range to the N range, the AT shifter controller 50a receives the signal from the position sensor 231 and moves the select lever 3 from the N range to the D range. It is determined whether or not the operation for switching to the range has been started. If the operation has started, the process proceeds to step S32. If the operation is not started, the process is terminated (in that case, it may be re-executed at a predetermined timing or the like).

  In step S32, a signal for driving the motor 7 is output, and assist for switching the select lever 3 from the N range to the D range is started (assist control means).

  In step S33, when the assist is started, it is determined whether or not the mission is in the N range based on the information from the mission position 53 and the brake is on based on the brake information 53. If the condition is not satisfied, the process is terminated.

  In step S34, the idling stop controller 50b drives the cell motor 12 to restart the engine (engine start command means).

  In step S35, the assist control in step S32 is controlled in advance so that the switching to the D range position is completed at the timing when the restart of the engine is completed. Therefore, in this step, it is assumed that switching to the D range position is completed.

[Restarting from idle stop by simple operation]
In the second embodiment, when the vehicle restarts from the idle stop state, in addition to the brake release operation, an operation of switching the select lever 3 from the N range position to the D range position is performed.
Then, an appropriate assist control is performed for the operation of switching the select lever 3 to the D range position. In this control, the switching to the D range position is completed within a predetermined time, and the restart of the engine is completed within the predetermined time (step S34).
As a result, it is possible to start the vehicle by switching the range position to the D range, releasing the brake and stepping on the accelerator.
In addition, the time until the vehicle restarts after the idling stop operation is shortened.

Explain the effect. In addition to the above (1), the vehicle automatic shift operating device of the second embodiment has the following effects.
(4) In the above (1), the controller 50 starts the assist control when there is an operation input to the D range position after the shift to the N range position in step S15 executed by the AT shift controller 50a. The idling stop controller 50b that outputs a command to start the engine when the mission is in the N range position and the brake is on after the processing of steps S31 and S32 executed in step 50a and the start of assisting in step S32. Since the process of step S34 to be executed and the process of step S32 of the AT shifter controller 50a for controlling the output of the assist force so as to complete the movement of the select lever 3 to the D range position after the engine is started, the N range position is provided. Immediately after starting assistance to the D range position from It is possible to reduce the time to re-start by the engine is restarted, there is an advantage that it is possible to reliably prevent the switch to the D range before the engine since the start of the assist restarted.
