Abstract
An ECU executes a program including the steps of changing a target shift stage when a current shift change mode is set to an automatic shift change mode and when a driver has intention to change a shift stage, changing a shift range to an N range when he/she has intention for neutral, maintaining the automatic shift change mode when it is determined that he/she does not have intention for neutral but he/she has intention to switch the shift change mode and when such determination is made for the first time after return from the N range, and switching the shift change mode to a manual shift change mode when such determination is not made for the first time.
Claims12
A vehicle control device for controlling a vehicle incorporating an automatic transmission that selects as a shift change mode, any of an automatic shift change mode for automatically changing a speed ratio in accordance with a state of the vehicle and a manual shift change mode for changing stepwise a speed ratio in response to a driver's request, said automatic transmission switching a shift range between a power cut-off range for cutting off transfer of power from a power source and a power transfer range for transferring power from said power source, and for said automatic transmission, a plurality of shift stages that are changed in response to a request operation by said driver while said manual shift change mode is selected are set, comprising:
- a range switching unit for switching said shift range in response to said driver's request;
- and
- a mode selection unit for causing return from said power cut-off range to said power transfer range and holding said automatic shift change mode in response to a first request operation by said driver for changing a stage of said shift stage after said shift range is switched to said power cut-off range from a state of selection of said automatic shift change mode, and selecting said manual shift change mode in response to a second request operation for changing a stage of said shift stage.
A vehicle control method for controlling a vehicle incorporating an automatic transmission that selects as a shift change mode, any of an automatic shift change mode for automatically changing a speed ratio in accordance with a state of the vehicle and a manual shift change mode for changing stepwise a speed ratio in response to a driver's request, said automatic transmission switching a shift range between a power cut-off range for cutting off transfer of power from a power source and a power transfer range for transferring power from said power source, and for said automatic transmission, a plurality of shift stages that are changed in response to a request operation by said driver while said manual shift change mode is selected are set, comprising the steps of:
- switching said shift range in response to said driver's request;
- and
- returning from said power cut-off range to said power transfer range and holding said automatic shift change mode in response to a first request operation by said driver for changing a stage of said shift stage after said shift range is switched to said power cut-off range from a state of selection of said automatic shift change mode, and selecting said manual shift change mode in response to a second request operation for changing a stage of said shift stage.
