Vehicle, control method for transmission and control device for transmission

A vehicle comprising:

• a transmission;
• and
• a control device that controls said transmission, wherein
• said control device
• selects one control mode from a plurality of control modes each setting a target value of a revolution speed of said transmission and prioritized in a predetermined order,
• when said control mode is changed, sets said target value so as to vary from the target value set in the control mode before change to the target value set in the control mode after change in accordance with the control mode that is higher in priority among the control mode before change and the control mode after change, and
• controls said transmission such that the revolution speed of said transmission reaches said target value, wherein
• a constant is predetermined for each control mode,
• when said control mode is changed, said control device sets at least one of a time constant, an upper limit value and a lower limit value in accordance with the constant determined for the control mode that is higher in priority among the control mode before change and the control mode after change, and
• said control device sets said target value so as to vary in accordance with at least one of said time constant, said upper limit value and said lower limit value.

• controls said transmission such that the revolution speed of said transmission reaches said target value, wherein
• a constant is predetermined for each control mode and each said constant includes at least one of a first constant and a second constant, and
• said control device
• sets said target value so as to vary in accordance with said first constant when the control mode before change is higher in priority than the control mode after change, and the constant determined for the control mode before change includes said first constant, and
• sets said target value so as to vary in accordance with said second constant when the control mode after change is higher in priority than the control mode before change, and the constant determined for the control mode after change includes said second constant.

A control method for a transmission, comprising the steps of:

• selecting one control mode from a plurality of control modes each setting a target value of a revolution speed of said transmission and prioritized in a predetermined order, wherein a constant is predetermined for each control mode;
• when said control mode is changed, setting at least one of a time constant, an upper limit value and a lower limit value in accordance with the constant determined for the control mode that is higher in priority among the control mode before change and the control mode after change, and setting said target value so as to vary in accordance with at least one of said time constant, said upper limit value and said lower limit value;
• and
• controlling said transmission such that the revolution speed of said transmission reaches said target value.
