Abstract

Provided is a control apparatus for vehicle that enables a driver to activate and deactivate a freewheeling mode at his/her discretion. A control apparatus 1 for vehicle switches the vehicle to a freewheeling mode in which power generated by an engine 2 of the vehicle is not transmitted to drive shafts 7 of the vehicle. The control apparatus 1 for vehicle includes: a decelerator having a plurality of deceleration gear stages for changing deceleration of the vehicle; and a manipulator 10 provided on steering 11 of the vehicle and configured to allow selection of the freewheeling mode in accordance with an operation performed by a driver. The vehicle transitions to the freewheeling mode upon the freewheeling mode being selected through an operation of the manipulator 10.

First claim

What is claimed is:

1. A control apparatus for vehicle for switching a vehicle to a freewheeling mode in which power generated by a power source of the vehicle is not transmitted to a drive shaft of the vehicle, the control apparatus comprising:
a decelerator having a plurality of deceleration gear stages for changing deceleration of the vehicle; and
a manipulator provided on steering of the vehicle and configured to allow selection of the freewheeling mode in accordance with an operation performed by a driver, wherein
the vehicle transitions to the freewheeling mode upon the freewheeling mode being selected through an operation of the manipulator, wherein
the manipulator is a shifter configured to allow shifts between the deceleration gear stages, and
the shifter includes
a first manipulator enabled to cause a shift to a deceleration gear stage corresponding to a lower deceleration than a deceleration corresponding to a currently selected deceleration gear stage and
a second manipulator enabled to cause a shift to a deceleration gear stage corresponding to a higher deceleration than the deceleration corresponding to the currently selected deceleration gear stage, and
the vehicle transitions to the freewheeling mode through an operation of either the first manipulator or the second manipulator, and
a fixed shift mode that allows shift between the plurality of deceleration gear stages based on an operation performed by the driver, and
an automatic shift mode that allows shift between the plurality of deceleration gear stages based on a running condition of the vehicle, wherein
the shifter is a paddle shifter,
keeping the first manipulator in an operated state for a first predetermined period of time causes a transition to the automatic shift mode and the freewheeling mode, and
keeping the first manipulator in the operated state for a second predetermined period of time causes a transition to the fixed shift mode and the freewheeling mode the second predetermined period of time being longer than the first predetermined period of time.

2. The control apparatus for vehicle according to claim 1 , wherein
the freewheeling mode is deactivated through an operation of the second manipulator.

3. The control apparatus for vehicle according to claim 1 , further comprising
an accelerator operation detector configured to detect an operation of an accelerator operator performed by the driver when the control apparatus is in the automatic shift mode and the vehicle is in the freewheeling mode, wherein
the freewheeling mode is deactivated upon the accelerator operation detector detecting the operation of the accelerator operator performed by the driver.

4. The control apparatus for vehicle according to claim 2 , wherein
the plurality of deceleration gear stages include a first deceleration gear stage corresponding to a higher deceleration than a deceleration corresponding to a deceleration gear stage to be selected when the vehicle is in the freewheeling mode, and
keeping the second manipulator in an operated state for the first predetermined period of time when the vehicle is in the freewheeling mode causes a shift to the first deceleration gear stage.

5. The control apparatus for vehicle according to claim 4 , wherein
keeping either the first manipulator or the second manipulator in the operated state for the second predetermined period of time when the vehicle is running in the first deceleration gear stage causes switching between the fixed shift mode and the automatic shift mode.
