    摘要: A method of operating a transport refrigeration system comprises: controlling, using a controller (30), a plurality of components of the refrigeration system and monitoring, using the controller, a plurality of operating parameters of the refrigeration system. The controlling comprises operating at least one of a prime mover (26), heater (48), and electric generation device (24). The operating parameters comprise at least one of a speed of the prime mover and a voltage of the electric generation device. The method comprises detecting, using the controller, when at least one of a heating mode and a defrost mode is required; activating, using the controller, the heater when at least one of the heating mode and the defrost mode is required; comparing, using the controller, the voltage of the electric generation device to a selected voltage; and controlling, using the controller, the speed of the prime mover in response to the voltage of the electric generation device.

    摘要: A frame for a vehicle includes a first housing and a second housing. The first housing and the second housing each define an interior space. The first housing and the second housing each comprises a first side portion and an opposing second side portion. The first housing and the second housing each include a first pair of triangular members coupled to the first side portion and a second pair of triangular members coupled to the second side portion. The first and second pairs of triangular members each support a wheel. A support assembly couples the first housing and the second housing. The support assembly includes an external lattice structure and an internal lattice structure. The external lattice structure is coupled to the first housing and the second housing. The internal lattice structure is coupled to the external lattice structure, the first housing, and the second housing.

    摘要: A transport refrigeration unit (TRU) system is provided and includes a TRU and an energy storage device (ESD). The TRU includes a TRU controller that is receptive of control data reflective of temperature profiles of one or more container compartments and which is configured to operate the TRU in accordance with the control data. The energy storage device (ESD) includes an ESD controller. The TRU and the ESD controllers are communicatively coupled. The ESD controller is configured to determine an energy need of the TRU to comply with the control data and the ESD, under control of the ESD controller, is configured to provide energy to the TRU in accordance with the energy need.

    摘要: An embodiment article delivery system, and corresponding method, includes a ground-based parent delivery vehicle and a plurality of child delivery vehicles configured to hold one or more articles for an article delivery to or from a customer location. The parent is configured to carry the child vehicles simultaneously, to transport them to at least one discharge location, and to discharge at least one of the child vehicles at discharge location. The child vehicle is configured to execute a hold instruction including waiting at a hold location following the discharge from the parent delivery vehicle. The child is further configured to navigate from the hold location to the customer location for the article delivery, the customer location differing from the hold location. Embodiment systems and methods can enable significant increases in product delivery efficiency or other article distribution efficiency.

    摘要: The delivery system includes a vehicle and a server. The vehicle includes a power storage device and a refrigerator. The server performs a delivery planning process for determining an expected delivery time. In the delivery planning process, the server is configured to transmit, to the vehicle, an inquiry as to reception of the delivery matter. When the vehicle receives the inquiry from the server, the vehicle is configured to set a receivable time period and transmit it to the server. When the vehicle sets the receivable time period, if the vehicle is in a state that the vehicle is able to receive power from the power supply facility, the vehicle is configured to set the receivable time period to be longer than the receivable time period set if the vehicle is not in the state that the vehicle is able to receive power from the power supply facility.
