- FIG. 11 is an explanatory view of the turning state in which the states of FIGS. 5 to 9 are superimposed.
- the angle 01 from the origin position A to the elastic repulsion position B is different for each vehicle.
- An easy-to-operate range is selected. However, if it is too small, the normal operation area becomes narrow and the elastic repulsion means is hit immediately, so the minimum value was set to 10 degrees in the present invention. If the angle is smaller than this, the stepping angle becomes strict and the operability becomes extremely poor.
- the maximum value is set to 30 degrees.
- a more desirable range is between 15 and 25 degrees.
- the angle ⁇ 2 from the elastic repulsion position B to the warning signal position C is a role of notifying too much depression by a warning signal.
- setting the elastic rebound position B to 0 to 5 degrees above the elastic repulsion position B It has the effect of immediately informing the driver that the driver has depressed the turning angle by sound, light, vibration, etc.However, if the warning signal is issued too soon, the normal operation area is unnecessarily narrowed, so it was set to 0 to 5 degrees. . Also, if the value of 02 is too large, the transmission of the warning signal is delayed, so the maximum value is set to +5 degrees. Desirably, the range is ⁇ 1 to 2 degrees.
- the warning signal position C is set on the minus side of the elastic rebound position B, the operation of the recognition means will not be a problem, only the order of the recognition means will be changed. Therefore, in claim 7, the warning signal position C is set at any one of ⁇ 5 degrees before and after the elastic repulsion position B.
- the angle ⁇ 3 from the elastic repulsion position B to the engine stop position D is the angle from the elastic repulsion position B to the forced engine stop. Therefore, if the angle is set to 0 degrees or less, the actuator operates below the elastic repulsion position B. Also, 0 3 is too large u
- the maximum value was set to 15 degrees because the stoppage of the runaway was delayed if the vehicle stopped. More preferably, it is in the range of 1 to 7 degrees.
- the angle 04 from the engine stop position D to the mechanical limit position E should be within the range of 1 to 5 degrees because if it is too small, the engine will stop at the mechanical limit without an engine stop signal. Since this is a structural play angle, its numerical significance is not strict.
- FIG. 12 is an explanatory diagram illustrating the relationship between the turning angle ⁇ of the accelerator device 5 and the turning bending moment ⁇ .
- the turning bending moment M caused by the elastic repulsion means 20 when exceeding the elastic repulsion position B is added to the repulsion force by the moment panel constant K2 of the elastic repulsion means 20, so that the stepping force increases rapidly, It is possible to sense that the abnormal state has been sensed.
- Such a large change in the moment spring constant exerts the effect of causing the driver to sense an erroneous operation, and by focusing on this, it is extremely simple, reliable, and inexpensive structure and easy to modify.
- the inventor was able to find the optimal moment panel constant by repeating many experiments and actual driving tests, by allowing the driver to sense abnormal driving conditions and prevent erroneous operation. .
