JP 2007-253912 A

  However, in the vehicle shifter device disclosed in Patent Document 1, the R position and the D position are selected by operating a shift lever, and the P position and the N position are selected by a push button provided at a position separated from the shift lever. It is necessary to perform this operation, and a complicated operation is required for the driver. For this reason, in the vehicle shifter device disclosed in Patent Literature 1, there is a concern that a driver's erroneous operation may be caused. Such an erroneous operation in switching the shift range becomes a serious problem in driving a vehicle that requires high safety.

  The present invention has been made to solve the above problems, and does not require a complicated operation for a driver, and can ensure high safety by suppressing an erroneous operation. It is an object of the present invention to provide a shifter device for a vehicle that can be used.

  A vehicle shifter device according to one embodiment of the present invention is a vehicle shifter device that switches a shift range of a vehicle among a plurality of ranges including a parking range, a reverse range, a neutral range, and a drive range based on a driver's operation. A shift lever that receives an input of the driver and defines a plurality of positions corresponding to each of the plurality of shift ranges, and the driver moves an upper end portion of the shift lever, and An operation load adding unit that applies an operation load in a direction opposite to the moving direction of the upper end when performing a shift operation between the positions of the shift lever. When the driver switches between the neutral range and the drive range, it is in the front-rear direction of the vehicle. When the driver switches between the parking range and the reverse range, it is in the width direction of the vehicle, and the operation load applying unit is more than when the driver switches between the neutral range and the drive range. Also, the configuration is such that the operation load applied when the driver switches between the parking range and the reverse range is smaller.

  In the vehicle shifter device according to the above aspect, the movement path of the upper end portion (the portion gripped and operated by the driver) of the shift lever is set to the reverse (R) range, the neutral (N) range, and the drive (D) range. When switching between the respective ranges, the direction is the vehicle front-rear direction. When switching between the R range and the parking (P) range, the direction is the vehicle width direction. Performing a shift operation between desired ranges is suppressed.

  In the vehicle shifter device according to the above aspect, the driver can perform a shift operation among the P range, the R range, the N range, and the D range by moving the shift lever. In contrast to the configuration disclosed in Document 1, it is difficult for the driver to memorize the trouble when operating.

  Furthermore, in the vehicle shifter device according to the above aspect, switching between the P range and the R range is more easily performed via the shift lever than switching between the N range and the D range. The operation load, which is a reaction force to the driver, is reduced. This focuses on the fact that when a person moves his / her arm, force is less likely to be applied when moving in the lateral direction than when moving in the front-back direction. As a result, the shift lever is moved in the lateral direction (vehicle width direction) where the force is less likely to be applied than when the upper end of the shift lever is moved in the front-rear direction where the force is easily applied (when switching between the N range and the D range). When the upper end of the gear is moved (when switching between the P range and the R range), the operation load on the driver is reduced, so that the driver is less likely to be troublesome at the time of the shift operation. it can. As a result, the vehicle shifter device according to the above aspect does not require a complicated operation for the driver at the time of the shift operation, and leads to suppression of an erroneous operation.

The bottom of the groove in the detent plate is elastically biased toward the bottom of the groove in the plate, and the bottom of the groove in the detent plate has a plurality of peaks so that the amount of protrusion of the detent plunger changes with movement of the shift lever. And a plurality of valleys are provided, the magnitude of the operation load is defined based on the shape of the ridge, It is also possible to.

  In the vehicle shifter device employing the above configuration, the detent in which the leading end slides along the groove bottom (groove bottom) of the detent plate on which the plurality of peaks and the plurality of valleys are formed. The operation load is configured to change depending on the amount of protrusion of the plunger. Thereby, when the driver moves the shift lever, an operation load due to the elastic force urged by the detent plunger is added. Therefore, in the vehicle shifter device employing the above configuration, the magnitude of the operation load can be reliably applied with a simple configuration.

  In the vehicle shifter device according to the above aspect, in the detent plate, when the plurality of valleys are placed in each of the plurality of positions, the plurality of valleys are positioned at positions corresponding to the plurality of positions. The plunger may be recessed so as to protrude, and the plurality of peaks may be projected in a region between the adjacent valleys so that the detent plunger retracts. it can.

  Further, in the vehicle shifter device adopting the above configuration, when the shift lever is to be moved between the respective positions, the detent plunger is retracted in order to go over the mountain portion, whereby the driver feels the operation load. Can be obtained. Therefore, in the vehicle shifter device employing the above-described configuration, it is possible to more reliably suppress an erroneous operation during the speed change operation.

  In the vehicle shifter device according to the aspect, the valley between the valley corresponding to the parking range and the valley corresponding to the reverse range includes the valley corresponding to the neutral range and the drive. The protruding height may be lower than the peak between the valley corresponding to the range.

  In the vehicle shifter device employing the above configuration, the height of the peak formed at the bottom of the groove of the detent plate is set between the valley corresponding to the N range and the valley corresponding to the D range, By changing between the valley corresponding to the P range and the valley between the valley corresponding to the R range, the magnitude of the operation load is realized. Therefore, in the vehicle shifter device employing the above configuration, the magnitude of the operation load can be reliably applied with a simple configuration.

  In the vehicle shifter device according to the aspect, the valley between the valley corresponding to the parking range and the valley corresponding to the reverse range includes the valley corresponding to the neutral range and the drive. The slope of the slope reaching the top of the peak may be smaller than that of the peak between the trough corresponding to the range.

  In the vehicle shifter device employing the above configuration, the inclination of the slope reaching the top of the peak formed at the bottom of the groove of the detent plate is determined between the valley corresponding to the N range and the valley corresponding to the D range. The magnitude of the operation load is realized by making the peak and the valley corresponding to the P range and the valley between the valley corresponding to the R range gentle and steep. Therefore, in the vehicle shifter device employing the above configuration, the magnitude of the operation load can be reliably applied with a simple configuration.

  In the vehicle shifter device according to the above aspect, the bottom of the groove in the detent plate may be configured to have a smooth curved surface in a direction in which the detent plunger moves.

  In the vehicle shifter device adopting the above configuration, since the groove bottom of the detent plate is configured to have a smooth curved surface, it is possible to prevent the driver from having to worry about moving the shift lever.

  In each of the above-described vehicle shifter devices, high safety can be ensured by not requiring the driver to perform complicated operations and suppressing erroneous operations.
