Technical Field

The present invention relates to a vehicle shift device.

Background

The vehicle shift device is provided on a center console or an instrument panel to receive an input from a driver regarding switching of a shift range. As a vehicle shift device, there are a mechanical vehicle shift device mechanically coupled to an automatic transmission by a cable or the like, and a shift-by-wire (shift by wire) type vehicle shift device that detects a position of a shift lever selected by a driver by an electric signal and transmits information on the detected position to a control unit by an electric signal to execute a shift change.

The shift-by-wire type vehicular shift device can make the support structure of the shift lever compact and also make the device compact as a whole.

Patent document 1 discloses a vehicle shift device in which a reverse (R) position and a forward (D) position are selected by operating a shift lever, and a parking (P) position and an idle (N) position are selected and released by a push switch.

Patent document 1: japanese laid-open patent publication No. 2007-253912

However, in the vehicle shift device disclosed in patent document 1, the R position and the D position are selected by the operation of the shift lever, whereas the P position and the N position need to be selected by the operation of the button provided at a position separated from the shift lever, and a complicated operation is required for the driver. Therefore, in the vehicle shift device disclosed in patent document 1, there is a possibility that an erroneous operation by the driver is caused. Such an erroneous operation in switching the shift range poses a serious problem in driving a vehicle requiring high safety.

Disclosure of Invention

The present invention has been made to solve the above-described problems, and an object thereof is to provide a vehicle shift device capable of suppressing an erroneous operation by a driver and ensuring high safety.

A vehicle shift device according to an aspect of the present invention is a vehicle shift device that switches between a plurality of shift ranges including a parking range, a reverse range, a neutral range, and a forward range, and includes: a shift lever operated by a driver and moved between positions corresponding to the plurality of shift positions; and a lever position holding unit that holds a position of the shift lever, wherein a path along which an upper portion of the shift lever moves between the reverse position, the neutral position, and the forward position, and a path along which the upper portion of the shift lever moves between the parking position and the reverse position are coupled to intersect at their ends, and the driver's operation on the shift lever includes a 1 st operation and a2 nd operation, the 1 st operation being performed when the shift lever is moved between the neutral position and the reverse position, and the 2 nd operation being performed when the shift lever is moved between the parking position and the reverse position.

In the vehicle shift device of the above aspect, since the movement path of the upper end portion (the portion where the driver grips the shift lever) is defined to have different directions when switching between the reverse (R), neutral (N), and forward (D) gears and when switching between the parking (P) and R gears, the driver is prevented from unintentionally switching from the R gear to the P gear, or from undesirably switching from the P gear to the D gear, or the like, due to the difference in the operation direction of the shift lever.

In the vehicle shift device of the above aspect, the 1 st operation is requested to the driver who wants to switch between the R range and the N range, and the 2 nd operation is requested to the driver who wants to switch between the P range and the R range. Further, since the 2 nd operation is different in operation degree or operation degree from the 1 st operation, the driver can be prevented from erroneously operating the P range and the R range.

Therefore, in the vehicle shift device of the above aspect, it is possible to prevent the driver from performing an erroneous operation and ensure high safety.

In the vehicular shift device according to the above aspect, it is preferable that the shift lever includes a button provided at an upper portion thereof for the driver to operate, the 1 st operation is an operation in which the driver presses the button to a 1 st depth, and the 2 nd operation is an operation in which the driver presses the button to a2 nd depth deeper than the 1 st depth.

In the vehicle shift device configured as described above, since the 2 nd operation is an operation in which the push button is pushed deeper than the 1 st operation, the driver needs to push the push button deeper intentionally when switching between the P range and the R range, and thus erroneous operation can be prevented more reliably.

In the vehicular shift device according to the above aspect, it is preferable that the shift lever further includes: the lock lever includes a lever main body that is a cylindrical body, a shift lever head that is attached to an upper portion of the lever main body, and a lock lever that protrudes from a lower portion of the shift lever head toward an outer side in a radial direction of the lever main body with respect to the lever main body, wherein the push button is provided at an upper end portion of the lever main body, and the lock lever moves up and down in a cylinder axis direction of the lever main body in response to a pressing operation of the push button by the driver, and is unlocked from the lock/lock of the lever position holding portion by the up and down movement.

In the vehicle shift device having the above configuration, the lock lever moves up and down in response to the push operation of the button by the operation of the driver, and the lock/lock release with the lever position holding portion is performed by the up and down movement, so that the position holding of the shift lever at each position can be reliably performed with a simple configuration.

In the vehicle shift device according to the above aspect, it is preferable that the lock lever includes: a 1 st locking bar protruded toward one direction of the radial direction of the bar body; and a2 nd locking lever projecting toward a side opposite to the 1 st locking lever in a radial direction of the lever main body, the 1 st locking lever being integrally formed by a base end portion and a tip end portion, the base end portion extending linearly from the lever main body side toward the one direction, the tip end portion being bent from a tip end portion of the base end portion in a direction intersecting the tip end portion, the 2 nd locking lever extending linearly toward the opposite side, the lever position holding portion being a lock plate provided with a plurality of concave portions which are recessed upward corresponding to a plurality of shift positions of the shift lever, respectively, the lock plate being integrally formed by a 1 st extending portion and a2 nd extending portion, the 1 st extending portion being along a moving path of the shift lever when the driver switches between the parking position and the reverse position, the 2 nd extending portion has an L-shape as a whole as viewed from above along a movement path of the shift lever when the driver switches among the reverse gear, the neutral gear, and the forward gear, and the recess for locking the 1 st locking lever when the parking gear and the reverse gear are selected is formed in the 1 st extending portion, and the recess for locking the 2 nd locking lever when the reverse gear, the neutral gear, and the forward gear are selected is formed in the 2 nd extending portion.

In the vehicle shift device configured as described above, the 1 st engagement lever and the 2 nd engagement lever protrude from the lever main body, and the protruding directions of the 1 st engagement lever and the 2 nd engagement lever from the lever main body are opposite. In the vehicle shift device configured as described above, the lock plate has an L-shape in plan view (may have an inverted L-shape depending on the direction of view).

Therefore, in the vehicle shift device configured as described above, the position of the shift lever is reliably held by engaging at least one of the 1 st engagement lever and the 2 nd engagement lever with the lock plate serving as the lever position holding portion.

In the vehicular shift device according to the above aspect, it is preferable that the lock lever is elastically urged upward in the axial direction of the lever main body, the lock lever is located at an upper end of a movable range of the lock lever when the driver does not push the button, and the lock plate locks at least one of the 1 st lock lever and the 2 nd lock lever in correspondence with each of the plurality of shift positions of the shift lever.

In the vehicle shift device configured as described above, the lock lever is elastically biased upward, and when the driver does not push the button, the lock lever is biased toward the bottom of the recess of the lock plate. Thus, in the vehicle shift device configured as described above, the position of the shift lever is reliably held at a certain position in a state where the driver does not push the button.

In the vehicular shift device according to the above aspect, it is preferable that the plurality of recesses provided in the 1 st extending portion of the lock plate include: a 1 st recess that latches the 1 st latch lever when the parking range is selected by the driver; and a2 nd recess that locks the 1 st detent lever when the reverse gear is selected by the driver, wherein the plurality of recesses provided in the 2 nd extending portion of the detent plate include: a 3 rd recess for locking the 2 nd locking lever when the reverse gear is selected by the driver; and a 4 th recessed portion configured to engage the 2 nd locking lever when the neutral position is selected by the driver, wherein a 1 st protruding portion protruding downward is provided between the 1 st recessed portion and the 2 nd recessed portion in the 1 st extending portion of the lock plate, a2 nd protruding portion protruding downward is provided between the 3 rd recessed portion and the 4 th recessed portion in the 2 nd extending portion of the lock plate, and a relative height of the 1 st protruding portion with respect to bottoms of the 1 st recessed portion and the 2 nd recessed portion is higher than a relative height of the 2 nd protruding portion with respect to bottoms of the 3 rd recessed portion and the 4 th recessed portion.

In the vehicle shift device configured as described above, since the relative height of the 1 st convex portion with respect to the bottoms of the 1 st concave portion and the 2 nd concave portion is higher than the relative height of the 2 nd convex portion with respect to the bottoms of the 3 rd concave portion and the 4 th concave portion, when the driver wants to switch between the P range and the R range, the push-down depth of the push button needs to be increased, and the driver is required to operate the push button consciously. This can prevent the driver from performing an erroneous operation.

In the vehicular shift device according to the above aspect, it is preferable that the 1 st lock lever is locked to the 2 nd recessed portion and the 2 nd lock lever is locked to the 3 rd recessed portion when the reverse gear is selected by the driver.

In the vehicle shift device configured as described above, when the R range is selected, the 1 st engagement lever engages with the 2 nd recessed portion, and the 2 nd engagement lever engages with the 3 rd recessed portion. Accordingly, when the R range is switched to the P range or the R range is switched to the N range, the driver is required to push the button, and therefore, it is possible to prevent an erroneous operation.

In this specification, the vertical direction refers to the vertical direction of the vehicle.

The invention has the following effects:

in each of the vehicle shift devices described above, it is possible to suppress an erroneous operation by the driver and ensure high safety.
