Abstract
A controller for a vehicle is configured to determine an amount of torque to be generated by a propulsion source of the vehicle during a shift from an initial gear of a transmission of the vehicle to a target gear of the transmission. The controller is configured to determine the amount of torque based on a position of an acceleration pedal of the vehicle, a first pedal map for the initial gear, and a second pedal map for the target gear. The controller is further configured to output, during the shift from the initial gear to the target gear, one or more commands to control one or more operating parameters of the propulsion source to generate the amount of torque.
Claims20
A controller for a vehicle, the controller configured to:
- determine an amount of torque to be generated by a propulsion source of the vehicle during a shift from an initial gear of a transmission of the vehicle to a target gear of the transmission, based on a position of an acceleration pedal of the vehicle, a first pedal map for the initial gear, and a second pedal map for the target gear, wherein the second pedal map is different than the first pedal map;
- and
- output, during the shift from the initial gear to the target gear, one or more commands to control one or more operating parameters of the propulsion source to generate the amount of torque.
A system comprising:
- means for determining an amount of torque to be generated by a propulsion source of a vehicle during a shift from an initial gear of a transmission of the vehicle to a target gear of the transmission, based on a position of an acceleration pedal of the vehicle, a first pedal map for the initial gear, and a second pedal map for the target gear, wherein the second pedal map is different than the first pedal map;
- and
- means for outputting, during the shift from the initial gear to the target gear, one or more commands to control one or more operating parameters of the propulsion source of the vehicle to generate the amount of torque.
A method comprising:
- determining an amount of torque to be generated by a propulsion source of a vehicle during a shift from an initial gear of a transmission of the vehicle to a target gear of the transmission based on a position of an acceleration pedal, a first pedal map for the initial gear, and a second pedal map for the target gear, wherein the second pedal map is different than the first pedal map;
- and
- outputting, during the shift from the initial gear to the target gear, one or more commands to control one or more operating parameters of the propulsion source to generate the amount of torque.
A computer-readable storage medium comprising instructions that, when executed by at least one processor of a computing device of a vehicle, cause the at least one processor to:
- determine an amount of torque to be generated by a propulsion source of the vehicle during a shift from an initial gear of a transmission of the vehicle to a target gear of the transmission, based on a position of an acceleration pedal of the vehicle, a first pedal map for the initial gear, and a second pedal map for the target gear, wherein the second pedal map is different than the first pedal map;
- and
- output, during the shift from the initial gear to the target gear, one or more commands to control one or more operating parameters of the propulsion source of the vehicle to generate the amount of torque.
