50 when being moved to four positions, such as engages when 3rd sensor 73 detects that soldered tooth 54 is moved to the second limiting section 53
When, the control of shifting system 1 is switched to P grades from D grades.
To be switched to D grades from R grades, when second component 40 is in the second position, driver makes third member 50 from the 4th
Position rotates to the third place.In rotary course, such as shown in Figure 13 and Figure 14, the soldered tooth that is connect with third member 50
54 from the position engaged with the second limiting section 53, is moved to the position engaged with the first limiting section 52.When 3rd sensor 73 is examined
When measuring third member 50 and being moved to the third place, such as when 3rd sensor 73 detects that soldered tooth 54 is moved to and the first limit
When position portion 52 engages, the control of shifting system 1 is switched to D grades from P grades.
To be switched to P grades from D grades, when third member 50 is in the third place, driver makes second component 40 from second
Position is moved to first position.In the exemplary embodiment, driver rotates second component 40 relative to the first component 30.It is revolving
During turning, such as is illustrated by figs. 11 and 12, it is recessed that the first protrusion 31 is moved to first via groove 43 from the second recess portion 42
In portion 41.When second sensor 72 detects that second component 40 is moved to the second position, such as when second sensor 72 detects
When being moved in the first recess portion 41 to the first protrusion 31, the control of shifting system 1 is switched to P grades from D grades.
To open EPB, when second component 40 is in first position, driver moves removable hood 20 relative to opening 12
It moves to close accommodating chamber 11.When first sensor 71 detects that removable hood 20 is moved to the position for closing accommodating chamber 11, change
EPB is opened in the control of gear system 1.
While the invention has been described with reference to exemplary embodiments thereof, however, it is understood that the present invention is not limited to above-mentioned realities
Apply the construction and method of example.On the contrary, it is intended to cover various modifications example and equivalent arrangements.In addition, although in various examples
Property combination and construction in show the various elements and method and step of disclosed invention, but including more, less element
Or other combinations of method are also fallen within the scope of the present invention.
