A tractor trailer roof heater apparatus for preventing snow and ice accumulation includes a reservoir configured to hold heater oil within an inner cavity and configured to be coupled to a tractor trailer. A heater is coupled to a bottom side of the reservoir within the inner cavity and is configured to heat the heater oil. A pump is coupled to a top side of the reservoir and has a draw tube extending through a pump aperture into the inner cavity to draw the heater oil from the reservoir and push it through an outlet aperture through an oil tube. The oil tube is configured to be coupled within a roof of the tractor trailer to carry hot heater oil from the pump and then return the heater oil to the reservoir. A power supply is coupled to the pump and a thermostat is coupled to the reservoir.

A system and method are provided for automated cleaning of a loading container of a transport vehicle (e.g., dump truck, ejector, scraper), wherein the loading container includes controllable elements (e.g., hydraulic lift cylinders for a truck bin, an ejector blade) for transitioning between loaded and unloaded states. Characteristics of carryback material remaining in the loading container are estimated during a detected unloaded state of the transport vehicle, wherein whether to initiate an automated cleaning stage is determined based on at least one of the estimated characteristics. Upon determining to initiate the automated cleaning stage, performance of a cleaning routine is automatically directed during or in association with an unloading stage for the loading container via the controllable elements. The elements are controlled during the cleaning routine in accordance with a severity level selected from among various progressively increasing severity levels based on at least one of the estimated characteristics.

An anti-icing structure is for a charging door for a vehicle where the charging door is rotatably installed to an inlet housing with a charging inlet module to selectively open the charging inlet module. The anti-icing structure includes: a door inner cover hingedly connected to the inlet housing through a hinge member at a position corresponding to an opening portion formed in the inlet housing to open the charging inlet module; a door outer cover connected to the outer surface of the door inner cover; and a heating assembly installed between an edge portion of the outer surface of the door inner cover and an edge portion of the inner side of the door outer cover.

An apparatus and method for melting snow and/or ice on a vehicle comprises a precipitation sensor, a surface temperature sensor, an ambient temperature sensor, a heater, and a programmable controller. The programmable controller comprises a memory unit and a processor to store and execute a cut-off surface temperature Tc, and program modules, respectively. A heater control module is configured to deactivate the heater based on the surface temperature being greater than the cut-off surface temperature. The heater could be an electric heater and a hydronic heater. The electric heater is electrically coupled to at least any one of, an alternator, an onboard power system, and a remote power source, via a relay. Further, the heater control module is configured to activate the heater based on an ambient temperature being lower than freezing point of water and precipitation being present outside the vehicle, thereby melting snow and/or ice on the vehicle.
