Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising a computer programmed to: determine an occupancy status of a vehicle based on received sensor data; adjust a cylinder deactivation of a powertrain of the vehicle in response to data indicating a critical condition of the powertrain based on the occupancy status; and in response to the data indicating the critical condition of the powertrain, increase cylinder deactivation more for an unoccupied status than for an occupied status, wherein a positive number of cylinders are active for the unoccupied status and for the occupied status. 2. The system of claim 1 , wherein the critical condition is a temperature of the powertrain exceeding a temperature threshold. 3. The system of claim 2 , wherein the computer is further programmed to determine the temperature threshold based on an ambient temperature. 4. A method comprising: determining an occupancy status of a vehicle based on received sensor data; and adjusting a cylinder deactivation of a powertrain of the vehicle in response to data indicating a critical condition of the powertrain based on the occupancy status; and in response to the data indicating the critical condition of the powertrain, increasing cylinder deactivation more for an unoccupied status than for an occupied status, wherein a positive number of cylinders are active for the unoccupied status and for the occupied status. 5. The method of claim 4 , wherein the critical condition is a temperature of the powertrain exceeding a temperature threshold. 6. The method of claim 5 , further comprising determining the temperature threshold based on an ambient temperature.
