Abstract
A computer is programmed to determine an occupancy status of a vehicle based on received sensor data; and adjust a parameter of a powertrain of the vehicle in response to data indicating a critical condition of the powertrain based on the occupancy status. The parameter may be one of engine speed, cylinder deactivation, transmission-shift time, and shift schedule.
Claims7
A system comprising a computer programmed to:
- determine an occupancy status of a vehicle based on received sensor data, wherein the occupancy status is one of an occupied status and an unoccupied status;
- adjust an engine speed of a powertrain of the vehicle in response to data indicating a critical condition of the powertrain based on the occupancy status, wherein the powertrain is active for the unoccupied status and for the occupied status;
- and
- in response to the data indicating the critical condition of the powertrain, increase the engine speed more for the unoccupied status than for the occupied status.

A system comprising a computer programmed to:
- determine an occupancy status of a vehicle based on received sensor data;
- determine a temperature threshold based on an ambient temperature;
- and
- adjust a parameter of a powertrain of the vehicle based on the occupancy status in response to data indicating a temperature of the powertrain exceeding the temperature threshold;
- wherein the parameter is one of an engine speed, cylinder deactivation, transmission-shift time, or threshold to shift of a shift schedule.
