Abstract
A vehicle includes a traction battery and a controller. The controller, responsive to a command to enter a highway, confirmation the traction battery can output power to accelerate the vehicle to enter the highway via an entrance at a same speed as traffic on the highway in a vicinity of the entrance, and an increase in temperature beyond a threshold of the traction battery predicted to occur on the highway due to expected commands to maintain the same speed on the highway with power from the traction battery, increases cooling of the traction battery prior to entering the highway.
Claims19
A vehicle comprising:
- a traction battery;
- and
- a controller programmed to, responsive to (i) a command to enter a highway, (ii) confirmation the traction battery can output power to accelerate the vehicle to enter the highway via an entrance at a same speed as traffic on the highway in a vicinity of the entrance, and (iii) an increase in temperature beyond a threshold of the traction battery predicted to occur on the highway due to expected commands to maintain the same speed on the highway with power from the traction battery, increase cooling of the traction battery prior to entering the highway.
A method for controlling a vehicle , comprising:
- responsive to (i) receiving a command to enter a highway via a first of a plurality of entrances and (ii) confirming a traction battery cannot output power to accelerate the vehicle to enter the highway via the first of the plurality of entrances at a same speed as traffic on the highway in a vicinity of the first of the plurality of entrances, operating by a controller the vehicle to bypass the first of the plurality of entrances and approach another of the plurality of entrances.
A vehicle comprising:
- a traction battery configured to output power for propulsion of the vehicle;
- and
- one or more controllers programmed to, responsive to indication that power of the traction battery output for propulsion of the vehicle will not maintain a same speed as traffic on a highway due to a predicted increase in temperature of the traction battery, operate the vehicle to exit the highway via a next available exit.
