Outside air temperature correction for a vehicle
View Patent ↗Methods, control systems, and vehicle are provided for controlling a vehicle that has a rechargeable energy storage system (RESS). A method includes storing with a control module a chosen outside air temperature (OAT) that is based on data from an OAT sensor and a cooling cycle of the RESS, and controlling the vehicle with the chosen OAT when a cooling cycle of the RESS is indicated. The control system and vehicle include control modules configured to perform the method.
1. A method for controlling a vehicle that has a rechargeable energy storage system (RESS), the method comprising:
storing with a control module a chosen outside air temperature (OAT) that is based on data from an OAT sensor and a cooling cycle of the RESS; and
controlling the vehicle with the chosen OAT when a cooling cycle of the RESS is indicated.
2. The method of claim 1 wherein controlling the vehicle further includes controlling the vehicle with the chosen OAT when the vehicle is in one of a charging mode and an off-power mode.
3. The method of claim 2 wherein storing the chosen OAT further includes storing data from the outside air temperature (OAT) sensor as the chosen OAT when the cooling cycle of the RESS is not indicated.
4. The method of claim 3 wherein storing a chosen OAT further includes storing data from the outside air temperature (OAT) sensor as the chosen OAT when the active cooling cycle of the RESS is requested.
5. The method of claim 3 wherein storing a chosen OAT further includes storing data from the outside air temperature (OAT) sensor when an electrical signal indicating an active cooling request is detected.
6. The method of claim 1 further comprising starting a cooldown timer when the cooling cycle of the RESS ends, and wherein controlling a cooling cycle of the RESS is indicated includes controlling the vehicle based on the chosen OAT when one of the cooling cycle and the cooldown timer is active.
7. The method of claim 6 wherein controlling the vehicle further includes controlling the vehicle when the vehicle is in one of a charging mode and an off-power mode, the cooling cycle is inactive, and the cooldown timer is inactive.
8. A control system for controlling a vehicle that has a rechargeable energy storage system (RESS), the control system comprising:
an outside air temperature (OAT) sensor; and
a control module that:
stores a chosen outside air temperature (OAT) that is based on data from an OAT sensor and a cooling cycle of the RESS; and
controls the vehicle with the chosen OAT when a cooling cycle of the RESS is indicated.
9. The control system of claim 8 wherein the control logic controls the vehicle based on the chosen OAT when the vehicle is in one of a charging mode and an off-power mode.
10. The control system of claim 9 wherein the control logic stores data from the OAT sensor as the chosen OAT when the cooling cycle of the RESS is not indicated.
11. The control system of claim 10 wherein the control logic stores data from the outside air temperature (OAT) sensor as the chosen OAT when the active cooling cycle of the RESS is requested.
12. The control system of claim 8 wherein the control logic starts a cooldown timer when the cooling cycle of the RESS ends, and wherein the cooling cycle of the RESS is indicated when one of the cooling cycle and the cooldown timer is active.
13. The control system of claim 12 wherein the control logic stores data from the OAT sensor as the chosen OAT when the vehicle is in one of a charging mode and an off-power mode, the cooling cycle is inactive, and the cooldown timer is inactive.
14. The control system of claim 8 further including a heat exchanger disposed in proximity to the OAT sensor, wherein the heat exchanger is coupled for thermal communication with the RESS system.
15. A vehicle, comprising:
an outside air temperature (OAT) sensor;
a rechargeable energy storage system (RESS); and
a control module having control logic that:
stores a chosen outside air temperature (OAT) that is based on data from an OAT sensor and a cooling cycle of the RESS; and
controls the vehicle with the chosen OAT when a cooling cycle of the RESS is indicated.
16. The vehicle of claim 15 wherein the control logic controls the vehicle based on the chosen OAT when the vehicle is in one of a charging mode and an off-power mode.
17. The vehicle of claim 16 wherein the control logic stores data from the outside air temperature (OAT) sensor as the chosen OAT when the cooling cycle of the RESS is requested.
18. The vehicle of claim 15 wherein the control logic starts a cooldown timer when the cooling cycle of the RESS ends, and wherein the control logic controls the vehicle based on the chosen OAT when one of the cooling cycle and the cooldown timer is active.
19. The vehicle of claim 15 further comprising a heat exchanger disposed in proximity to the OAT sensor and coupled for thermal communication with the RESS system.
20. The vehicle of claim 19 further comprising a front fascia, and wherein the heat exchanger is a condenser disposed in the front fascia, and wherein the OAT sensor is disposed in the front fascia.
