Abstract
Techniques are described for managing temperature in an autonomous vehicle. An exemplary method comprises performing autonomous driving operations that operate the autonomous vehicle in an autonomous mode, receiving one or more messages from a temperature sensor associated with an electrical device located on or in the autonomous vehicle while the autonomous vehicle is operated in the autonomous mode, determining a cooling technique to reduce the temperature of electrical device, and performing the cooling technique.
Claims20
A system for managing temperature in an autonomous vehicle, comprising:
- one or more computers located in the autonomous vehicle and including one or more processors configured to:
- perform autonomous driving operations that operate the autonomous vehicle in an autonomous mode;
- receive one or more messages from a temperature sensor associated with an electrical device located on or in the autonomous vehicle while the autonomous vehicle is operated in the autonomous mode, wherein each message includes a temperature value that indicates a temperature at which the electrical device is operating;
- determine a cooling technique to reduce the temperature of electrical device, wherein the cooling technique is determined based on a comparison between the temperature of the electrical device and a pre-determined threshold value from a set of two or more pre-determined threshold values;
- and
- perform the cooling technique.
A method of managing temperature in an autonomous vehicle, comprising:
- performing autonomous driving operations that operate the autonomous vehicle in an autonomous mode;
- receiving a first message that includes a first temperature value from a temperature sensor associated with an electrical device located on or in the autonomous vehicle while the autonomous vehicle is operated in the autonomous mode;
- performing a first determination that the first temperature value is greater than a first pre-determined threshold value;
- sending, in response to the first determination, a first command that instructs a temperature management device associated with the electrical device to cool the electrical device;
- receiving, after sending the first command, a second message that includes a second temperature value from the temperature sensor associated with the electrical device;
- performing a second determination that the second temperature value is greater than a second pre-determined threshold value, wherein the second pre-determined threshold value is higher than the first pre-determined threshold value;
- and
- performing, in response to the second determination, an autonomous driving emergency operation.
A non-transitory computer readable storage medium having code stored thereon, the code, when executed by a processor, causing the processor to implement a method of managing temperature in an autonomous vehicle, comprising:
- performing autonomous driving operations that operate the autonomous vehicle in an autonomous mode;
- receiving a first message that includes a first temperature value from a temperature sensor associated with an electrical device located on or in the autonomous vehicle while the autonomous vehicle is operated in the autonomous mode;
- performing a first determination that the first temperature value is greater than a first pre-determined threshold value;
- sending, in response to the first determination, a first command that instructs a temperature management device associated with the electrical device to cool the electrical device;
- receiving, after sending the first command, a second message that includes a second temperature value from the temperature sensor associated with the electrical device;
- performing a second determination that the second temperature value is greater than a second pre-determined threshold value, wherein the second pre-determined threshold value is higher than the first pre-determined threshold value;
- and
- performing, in response to the second determination, an autonomous driving emergency operation.
