Abstract
A shift control ECU includes the steps of storing a position of a shift lever; starting a count-up timer when the shift lever comes to a neutral position; and recognizing a driver's request for the neutral position when a count-up timer value attains TN(1) if the stored shift lever position is a home position and when a count-up timer value attains TN(2) if the stored shift lever position is not the home position. Here, TN(1) is set to be smaller than TN(2).
Claims8
A shift device of a transmission, comprising:
- a path for reaching a plurality of shift positions;
- and
- a momentary-type movable portion manipulated so as to move along said path by a driver;
- wherein
- said movable portion is held at a predetermined home position when it is not manipulated by the driver,
- said shift device further comprises
- recognition means for recognizing a shift position requested by the driver from holding of said movable portion at said shift position for a predetermined recognition time, and
- output means for outputting a control signal to said transmission so as to attain a power transmission state corresponding to said recognized shift position,
- said path includes said home position, a first shift position representing one of the plurality of shift positions, and a second shift position representing one of the plurality of shift positions and provided between said home position and said first shift position,
- when it is recognized that said movable portion is located at said first shift position, the power transmission state by said transmission is set to a first state, and when it is recognized that said movable portion is located at said second shift position, the power transmission state by said transmission is set to a second state different from said first state, and
- said shift device further comprises setting means for setting said recognition time in accordance with a moving direction of said movable portion along said path.
