Abstract
A controller includes a control unit configured to perform stepwise shift that upshifts a CVT in a stepped manner to accelerate a vehicle. The control unit performs a downshift control configured to downshift the continuously variable transmission in a case in which an accelerator pedal is continuously stepped on from before prohibition of the stepwise shift to after prohibition of the stepwise shift.
Claims7
A vehicle control device configured to control a vehicle having a continuously variable transmission, the control device comprising:
- a control unit configured to perform stepwise shift that upshifts the continuously variable transmission in a stepped manner to accelerate the vehicle, wherein
- the control unit includes, as prohibition conditions of the stepwise shift, a first prohibition condition on the basis of an insufficient driving force judgment, and
- the control unit performs a downshift control configured to downshift the continuously variable transmission in a case in which an accelerator pedal is continuously stepped on from before prohibition of the stepwise shift to after the prohibition by the first prohibition condition of the stepwise shift.
A vehicle control device configured to control a vehicle having a continuously variable transmission, the control device comprising:
- a control unit configured to perform stepwise shift that upshifts the continuously variable transmission in a stepped manner to accelerate the vehicle, wherein
- the control unit performs a downshift control configured to downshift the continuously variable transmission in a case in which an accelerator pedal is continuously stepped on from before prohibition of the stepwise shift to after the prohibition of the stepwise shift, and
- the control unit does not perform the downshift control in a case in which an accelerator pedal amount becomes less than a predetermined value while the accelerator pedal is continuously stepped on from before the prohibition of the stepwise shift to after the prohibition of the stepwise shift.
A vehicle control device configured to control a vehicle having a continuously variable transmission, the control device comprising:
- a control unit configured to perform stepwise shift that upshifts the continuously variable transmission in a stepped manner to accelerate the vehicle, wherein
- the control unit performs a downshift control configured to downshift the continuously variable transmission in a case in which an accelerator pedal is continuously stepped on from before prohibition of the stepwise shift to after the prohibition of the stepwise shift,
- the control unit includes, as prohibition conditions of the stepwise shift, a first prohibition condition on the basis of an insufficient driving force judgment, and a second prohibition condition different from the first prohibition condition,
- the downshift control is performed in a case in which the stepwise shift is prohibited by the first prohibition condition, and
- the downshift control is not performed in a case in which the stepwise shift is prohibited by the second prohibition condition.
