Abstract

Embodiments include identifying improperly installed equipment in a heating and cooling system of a vehicle. Aspects include obtaining an initial reading from each of a plurality of sensors disposed in the vehicle, activating one or more of a heating system and a cooling system disposed in the vehicle, and obtaining a series of readings from each of the plurality of sensors. Aspects also include identifying, for each of the plurality of sensors, a delta value from the series of readings, comparing, for each of the plurality of sensors, the delta value to an expected delta value, identifying two or more sensors from the plurality of sensors that have been mismatched based on differences between the delta values and the expected delta values, and updating a mapping of the two or more sensors in a software of the vehicle.

Claims (42)

1 . A method for identifying mismatched sensors in a vehicle, the method comprising:

obtaining an initial reading from each of a plurality of sensors disposed in the vehicle;

activating one or more of a heating system and a cooling system disposed in the vehicle;

obtaining a series of readings from each of the plurality of sensors;

identifying, for each of the plurality of sensors, a delta value from the series of readings;

comparing, for each of the plurality of sensors, the delta value to an expected delta value;

identifying two or more sensors from the plurality of sensors that have been mismatched based on differences between the delta values and the expected delta values; and

updating a mapping of the two or more sensors in a software of the vehicle,

wherein the plurality of sensors are temperature sensors.

2 . The method of claim 1 , wherein identifying two or more sensors from the plurality of sensors that have been mismatched based on the differences between the delta values and the expected delta values comprises:

identifying a first sensor of the plurality of sensors that has a first delta value that is not within a first threshold range of a first expected delta value;

identifying a second sensor of the plurality of sensors that has a second delta value that is not within a second threshold range of a second expected delta value; and

determining that the first delta value is within the second threshold range of the second expected delta value and that the second delta value is within the first threshold range of the first expected delta value.

3 . The method of claim 2 , wherein the first threshold range and the second threshold range are different.

4 . The method of claim 1 , wherein the series of readings from each of the plurality of sensors are obtained during a predetermined time period after activation of the one or more of the heating system and the cooling system.

5 . The method of claim 1 , wherein the mapping in the software of the vehicle is a logical mapping between each of the plurality of sensors and a variable in the software.

6 . The method of claim 1 , wherein the one or more of the heating system and the cooling system are configured to control a temperature of a battery pack of the vehicle.

7 . The method of claim 1 , further comprising generating a notification to a user interface of the vehicle indicating the identification of the mismatched sensors.

8 . A method for identifying mismatched sensors in a vehicle, the method comprising:

activating one or more of a heating system and a cooling system disposed in the vehicle;

obtaining a series of readings from each of a plurality of sensors disposed in the vehicle;

inputting the series of readings from each of the plurality of sensors and an operational status of the one or more of the heating system and the cooling system into a trained machine learning model;

receiving an indication from the trained machine learning model an identification that two or more sensors from the plurality of sensors that are mismatched; and

updating a mapping of the two or more sensors in a software of the vehicle.

9 . The method of claim 8 , wherein the plurality of sensors are temperature sensors.

10 . The method of claim 8 , wherein the trained machine learning model is trained using historical readings from sensors disposed in a test vehicle and an operational status of heating system and cooling systems corresponding to the historical readings.

11 . The method of claim 8 , wherein the series of readings from each of the plurality of sensors are obtained during a predetermined time period after activation of the one or more of the heating system and the cooling system.

12 . The method of claim 8 , wherein the mapping in the software of the vehicle is a logical mapping between each of the plurality of sensors and a variable in the software.

13 . The method of claim 8 , wherein the one or more of the heating system and the cooling system are configured to control a temperature of a battery pack of the vehicle.

14 . The method of claim 8 , further comprising receiving from the trained machine learning model an identification of a check valve that has been improperly installed, wherein the check valve is disposed in a fluid pathway of the one or more of the heating system and the cooling system.

15 . A method for identifying an improperly installed check valve in a vehicle, the method comprising:

activating one or more of a heating system and a cooling system disposed in the vehicle;

obtaining a series of readings from one or more sensors disposed in the vehicle;

identifying, for each of the one or more of sensors, a delta value from the series of readings;

comparing, for each of the one or more of sensors, the delta value to an expected delta value;

identifying a check valve disposed in the vehicle that has been improperly installed based on differences between the delta values and the expected delta values; and

generating an alert that identifies the check valve.

16 . The method of claim 15 , wherein the one or more sensors include one or more of a pressure sensor, a temperature sensor, and a flow rate sensor.

17 . The method of claim 15 , wherein the one or more sensors are disposed in a fluid pathway of the one or more of the heating system and the cooling system.

18 . The method of claim 17 , wherein the check valve is configured to control a direction of flow in the fluid pathway.

19 . The method of claim 15 , wherein the series of readings from each of the one or more sensors are obtained during a predetermined time period after activation of the one or more of the heating system and the cooling system.

20 . The method of claim 15 , wherein the one or more of the heating system and the cooling system are configured to control a temperature of a battery pack of the vehicle.
