Abstract
A switching device includes an operation lever capable of being turned in a first direction and in a second direction with respect to a neutral position, a first switch to detect a condition when the operation lever is moved to a first operation position, a second switch to detect a condition when the operation lever is moved to a second operation position symmetric to the first operation position, and a control unit to control a multistage function in a stepwise manner to switch operating states in a stepwise manner such that the condition of control of the multistage function is switched up in a stepwise manner based on a condition detected by the first switch and such that the condition of control of the multistage function is switched down in a stepwise manner based on a condition detected by the second switch.
Claims12
A switching device comprising:
- an operation lever capable of being turned in a first direction and in a second direction opposite to the first direction with respect to a neutral position;
- a first switch to detect that the operation lever is moved to a first operation position disposed in the first direction with respect to the neutral position;
- a second switch to detect that the operation lever is moved to a second operation position symmetric to the first operation position with respect to the neutral position;
- a control unit to control a multistage function having a plurality of operating states and provided in a vehicle such that the operating states are switched in a stepwise manner,
- a switch unit in which the first switch and the second switch are mounted;
- and
- a connection unit connecting the switch unit and the operation lever in a detachable manner,
- wherein the control unit switches up an operating state of the multistage function in a stepwise manner based on a condition detected by the first switch and switches down the operating state of the multistage function in a stepwise manner based on a condition detected by the second switch.
A switching device for a multistage function of a vehicle, the multistage function having a plurality of operating states, the switching device comprising:
- an operation lever movable in a first direction from a neutral position to a first position, and the operation lever is movable in a second direction from the neutral position to a second position, where the second direction is opposite to the first direction, and the second position is symmetric to the first position with respect to the neutral position;
- a first switch configured to detect the operation lever in the first position;
- a second switch configured to detect the operation lever in the second position;
- a switch unit in which the first switch and the second switch are mounted;
- a connection unit detachably connecting the switch unit to the operation lever;
- and
- a control unit configured to control the plurality of operating states of the multistage function based on a selected one of a plurality of predetermined state values, where the each of the state values corresponds to a respective one of the operating states, the control unit being configured to select one of the predetermined state values by,
- incrementing a control value if the first switch detects the operation lever in the first position,
- decrementing the control value if the second switch detects the operation lever in the second position, and
- subsequently selecting one of the state values that corresponds to the control value, and
- the control unit being further configured to output a control signal to the multistage function to engage one of the plurality of operating states that corresponds to the selected one of the state values.
