Systems and methods for gear shifting management in cooperative adaptive cruise control

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 a 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 a transmission shift event based on the received torque demand and the updated transmission shift map;
• and
• implement the determined transmission shift event.
