Abstract
Systems and methods for transmission gear shift management of a vehicle having cooperative adaptive cruise control (CACC) are provided. A method includes: enabling a cooperative adaptive cruise control (CACC) mode of a vehicle; updating a transmission shift map to adjust at least one threshold associated with a transmission shift event in response to enabling the CACC mode of the vehicle; receiving a torque demand from the vehicle in response to enabling the CACC mode of the vehicle; determining a transmission shift event based on the received torque demand and the updated transmission shift map; and implementing the determined transmission shift event.
Claims20
A method comprising:
- enabling a cooperative adaptive cruise control (CACC) mode of a vehicle;
- in response to enabling the CACC mode of the vehicle, updating a transmission shift map to adjust at least one threshold associated with a transmission shift event;
- in response to enabling the CACC mode of the vehicle, receiving a torque demand from the vehicle;
- determining the transmission shift event based on the received torque demand and the updated transmission shift map;
- and
- implementing the determined transmission shift event.
A method comprising:
- enabling a cooperative adaptive cruise control (CACC) mode of a vehicle;
- determining one or more CACC vehicle states;
- in response to enabling the CACC mode of the vehicle, predicting a vehicle gear down shift event based on look ahead information;
- determining that the vehicle can avoid the predicted vehicle gear down shift event based on the one or more CACC vehicle states;
- determining a transmission shift event based on the determination that the vehicle can avoid the predicted vehicle gear down shift event;
- and
- implementing the determined transmission shift event.
A system, comprising:
- a controller coupled to a powertrain of a vehicle, the controller configured to:
- enable a cooperative adaptive cruise control (CACC) mode of the vehicle;
- in response to enabling the CACC mode of the vehicle, update a transmission shift map to adjust at least one threshold associated with a transmission shift event;
- in response to enabling the CACC mode of the vehicle, receive a torque demand from the vehicle;
- determine the transmission shift event based on the received torque demand and the updated transmission shift map;
- and
- implement the determined transmission shift event.
