Shift operating means for operating the shift lever, shift lever operating state detecting means for detecting the operating state of the shift lever during shift operation, and evaluation data quantitatively indicating shift operability based on the output of the detecting means. And a memory means for storing an evaluation standard relating to the shift operability, the evaluation data obtained by the arithmetic means and the evaluation standard stored in the memory means are compared to judge whether the shift operability is good or bad. It is known to have a determination means so that the shift feeling can be evaluated in a unified and quantitative manner.

[0003]

However, when implementing such a shift feeling evaluation apparatus, there are the following problems. That is, since the shift lever of the transmission is normally operated in two orthogonal directions, that is, the shift direction and the select direction, even in the shift operation means of the shift feeling evaluation device,
It is necessary to be able to operate the shift lever in two directions. However, when the shift operation means is configured by using a fluid type actuator, for example, a hydraulic cylinder, it is difficult to accurately switch the operation and stop of the shift lever and the operation direction. On the other hand, when the shift operating means is configured by using an electric actuator, for example, an electric motor, it is not easy to obtain a sufficient operating force for operating the shift lever.

The present invention has been made in view of the above points, and an object of the present invention is to operate a shift lever in two directions by incorporating a cam mechanism when the shift operating means is constituted by a fluid cylinder. (EN) Provided is a shift feeling evaluation device capable of accurately and quickly performing a large operation force.

[0005]

In order to achieve the above object, the invention according to claim 1 is a shift feeling evaluating device for evaluating shift operability of a manual transmission, in which a shift lever of the transmission is stroked in a shift direction. The shift cylinder to be operated, the select cylinder to stroke the shift lever of the transmission in the select direction, and the shift lever of the transmission are engaged with each other, and receive the operating force from both cylinders to move together with the shift lever. A lever engaging member, a cam member fixed to the lever engaging member, and a cam member that is disengageable from the cam member.
First guide means having a linear guide groove for guiding the shift lever only in the shift direction, and disengageably arranged in the cam member, guide the shift lever in the shift direction, and in the middle thereof in the select direction. Also provided is second guide means having a bent guide groove for also guiding, and engagement / disengagement switching means for selectively engaging the guide groove of one of the guide means with the cam member. The configuration.

The invention according to claim 2 is dependent on the invention according to claim 1, and, in addition to the constituent features thereof, further delays the operating force when the shift lever of the transmission is stroked to each of the cylinders. A waiting mechanism for transmitting to the shift lever side is provided.

[0007]

With the above construction, in the invention according to claim 1,
When operating the shift lever to evaluate the shift operability of a manual transmission, first,
The engagement / disengagement switching means engages one guide groove of the first guide means and the second guide means with the cam member.
Then, when the guide groove of the first guide means and the cam member are engaged with each other, the shift cylinder is operated to stroke the shift lever together with the lever engaging member in the shift direction. At this time, the shift lever is reliably operated linearly in the shift direction and for a predetermined stroke below the guide of the guide groove.

Further, when the guide groove of the second guide means and the cam member are engaged with each other, both the shift cylinder and the select cylinder are operated to operate the shift lever. At this time, the shift lever first moves a predetermined stroke in the shift direction under the guide of the guide groove, then moves a predetermined stroke in the select direction, and then again moves a predetermined stroke in the shift direction. The shift lever is moved smoothly and surely. In particular, claim 2
In the case where each cylinder is provided with the waiting mechanism as in the invention described above, the shift lever is moved in a state similar to the case where a human shift operation is performed.

As described above, according to the shift feeling evaluating device of the present invention, when the shift lever is operated linearly in the shift direction, and when the shift lever is operated in the shift direction, the shift feeling is changed in the select direction. In any case, the shift lever is operated accurately and with a large operating force as prescribed by the operation of the fluid cylinder under the guide by the engagement between the guide groove of the guide means and the cam member. This is very advantageous in realizing the device.

In particular, according to the second aspect of the present invention, the operating force of the fluid cylinder is delayed by the waiting mechanism and transmitted to the shift lever side, so that the shift lever can be operated in a state close to a human shift operation. Therefore, shift evaluation can be appropriately performed.
