Abstract

A refuse vehicle includes a chassis, a body assembly coupled to the chassis, and a thermal stress mitigation system. The body assembly defines a refuse compartment. The thermal stress mitigation system is configured to mitigate against a thermal stress on the refuse vehicle. The thermal stress mitigation system includes a thermal stress mitigation substance, at least one of a container and a tank, one or more nozzles, a controller, one or more thermal sensors. The controller is structured to receive thermal stress data from the sensors, determine whether the thermal stress is greater than a threshold thermal stress based on the thermal stress data from the sensors, and operate the nozzles to deploy the thermal stress mitigation substance on the refuse vehicle responsive to determining that the thermal stress is greater than the threshold thermal stress.

First claim

1 . A vehicle comprising:
a chassis; a body assembly coupled to the chassis; and a thermal stress mitigation system comprising at least one nozzle coupled to the body assembly and operable to deploy a thermal stress mitigation substance, the thermal stress mitigation system configured to deploy the thermal stress mitigation substance into at least a portion of the body assembly.

2 . The vehicle of claim 1 , wherein the thermal stress mitigation system further comprises:
a controller communicatively coupled to and configured to operate the at least one nozzle; and one or more thermal sensors communicatively coupled to the controller and configured to detect a thermal stress on the vehicle.

3 . The vehicle of claim 2 , wherein the controller is configured to:
receive thermal stress data from the one or more thermal sensors; determine whether the thermal stress on the vehicle is greater than a threshold thermal stress based on the thermal stress data; and operate the at least one nozzle to deploy the thermal stress mitigation substance on the vehicle responsive to determining that the thermal stress is greater than the threshold thermal stress.

4 . The vehicle of claim 3 , wherein the controller is configured to provide a signal to a remote server based on determining that the thermal stress is greater than the threshold thermal stress.

5 . The vehicle of claim 1 , further comprising at least one of an engine or a motor;
wherein the thermal stress mitigation system is further configured to deploy the thermal stress mitigation substance onto the engine or the motor.

6 . The vehicle of claim 1 , further comprising an energy device, wherein the thermal stress mitigation system is positioned proximate the energy device.

7 . The vehicle of claim 6 , wherein the energy device is coupled to a rearward top portion of the body assembly.

8 . The vehicle of claim 6 , wherein the energy device is coupled to a rearward bottom portion of the body assembly.

9 . The vehicle of claim 1 , wherein the body assembly comprises a plurality of panels, a tailgate, and a cover.

10 . The vehicle of claim 9 , wherein the thermal stress mitigation system is configured to deploy the thermal stress mitigation substance onto at least one of the plurality of panels, the tailgate, or the cover.

11 . The vehicle of claim 9 , wherein:
the plurality of panels, the tailgate, and the cover cooperate to define a collection chamber; and the thermal stress mitigation system is configured to deploy the thermal stress mitigation substance into the collection chamber.

12 . A thermal stress mitigation system for a refuse vehicle, the thermal stress mitigation system comprising:
a thermal stress mitigation substance; a storage tank configured to store the thermal stress mitigation substance; one or more nozzles fluidly coupled to the storage tank and operable to deploy the thermal stress mitigation substance into a body of the refuse vehicle; a controller coupled to and configured to operate the one or more nozzles; and one or more thermal sensors coupled to the controller and configured to detect a thermal stress on the refuse vehicle.

13 . The thermal stress mitigation system of claim 12 , wherein the controller is configured to:
receive thermal stress data from the one or more thermal sensors; determine whether the thermal stress on the refuse vehicle is greater than a threshold thermal stress; and operate the one or more nozzles to deploy the thermal stress mitigation substance into the body responsive to determining that the thermal stress is greater than the threshold thermal stress.

14 . The thermal stress mitigation system of claim 13 , wherein at least a portion of the thermal stress mitigation system is configured to be coupled to the body of the refuse vehicle such that the one or more thermal sensors receive thermal stress data associated with the body assembly.

15 . The thermal stress mitigation system of claim 12 , wherein at least a portion of the thermal stress mitigation system is configured to be coupled to the refuse vehicle and proximal a refuse compartment of the refuse vehicle such that the one or more thermal sensors receive thermal stress data associated with the refuse compartment.

16 . The thermal stress mitigation system of claim 12 , wherein at least a portion of the thermal stress mitigation system is configured to be coupled to the refuse vehicle and proximal an energy device of the refuse vehicle such that the one or more thermal sensors receive thermal stress data associated with the energy device.

17 . The thermal stress mitigation system of claim 12 , wherein at least a portion of the thermal stress mitigation system is configured to be coupled to the refuse vehicle and proximal a lift assembly of the refuse vehicle such that the one or more thermal sensors receive thermal stress data associated with the lift assembly.

18 . A method of operating a thermal stress mitigation system, the method comprising:
receiving, by a controller, thermal data from one or more sensors regarding a thermal stress on a vehicle; determining, by the controller, whether the thermal stress on the vehicle is greater than a threshold thermal stress; and operating, by the controller, one or more nozzles to deploy a thermal stress mitigation substance into a body assembly of the vehicle responsive to determining that the thermal stress is greater than the threshold thermal stress.

19 . The method of claim 18 , wherein:
the one or more nozzles are coupled to the body assembly of the vehicle; and operating the one or more nozzles to deploy the thermal stress mitigation substance comprises causing the one or more nozzles to deploy the thermal stress mitigation substance into at least a portion of the body assembly.

20 . The method of claim 18 , further comprising providing a signal to a remote server based on determining that the thermal stress is greater than the threshold thermal stress.
