Abstract
A vehicle includes a transmission and a controller. The transmission is configured to transition between automatic and manual modes. The controller is programmed to, in response to the transmission operating in the manual mode and an absence of receiving a manual command to shift the transmission for a predetermined period of time, transition the operation of the transmission from the manual mode to the automatic mode. The controller is further programmed to, in response to the transmission operating in the manual mode, an absence of receiving the manual command to shift the transmission for the predetermined period of time, and a condition flagged to suppress an upshift in the transmission, remain in the manual mode.
Claims20
A vehicle comprising:
- a transmission configured to shift between a plurality of gears and transition between automatic and manual modes;
- a shifter configured to shift the transmission between the plurality of gears;
- and
- a controller programmed to,
- in response to the transmission operating in the automatic mode, automatically shift the transmission between the plurality of gears based on a shift schedule,
- in response to the transmission operating in the manual mode, shift the transmission between the plurality of gears based on receiving inputs from the shifter,
- in response to the transmission operating in the manual mode and an absence of receiving inputs from the shifter for a predetermined period of time, transition the operation of the transmission from the manual mode to the automatic mode, and
- in response to the transmission operating in the manual mode, an absence of receiving inputs from the shifter for a predetermined period of time, an operating condition corresponding to a condition for upshifting the transmission according to the shift schedule, and a secondary condition flagged to suppress an upshift in the transmission while in the manual mode, override transitioning to the automatic mode and remain in the manual mode such that transmission does not upshift.
A vehicle controller comprising:
- input channels configured to receive user input signals indicative of commands to shift a transmission of a vehicle in a manual mode;
- output channels configured deliver an output signal to transition operation of the transmission from the manual mode to an automatic mode;
- and
- control logic programmed to,
- in response to the transmission operating in the manual mode and an absence of receiving the user input signals to shift the transmission in the manual mode for a predetermined period of time, generate the output signal to transition the operation of the transmission to the automatic mode, and
- in response to the transmission operating in the manual mode, an absence of receiving the user input signals to shift the transmission in the manual mode for a predetermined period of time, and a condition flagged to suppress an upshift in the transmission, override generating the output signal to remain in the manual mode.
A vehicle comprising:
- a transmission configured to transition between automatic and manual modes;
- and
- a controller programmed to,
- in response to the transmission operating in the manual mode and an absence of receiving a manual command to shift the transmission for a predetermined period of time, transition the operation of the transmission from the manual mode to the automatic mode, and
- in response to the transmission operating in the manual mode, an absence of receiving the manual command to shift the transmission for the predetermined period of time, and a condition flagged to suppress an upshift in the transmission, remain in the manual mode.
