A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

The invention provides a new design of an intelligent pooling vehicle and trailer system equipped with an intelligent pooling vehicle and an intelligent electric powered trailer capable to improve the efficiency of the system, avoid off-tracking and make the system more user friendly. The rear powered tires train is capable to turn around a pivot, taking different positions with respect to the trailer. The independent electric motors on each tire of the trailer rear tires train provide additional power to the vehicle and steering capability of the trailer rear tires train. This allows better control of the rear of the trailer and instead to be only pull by the truck, the trailer may be driven by it self, by using different speeds on each of the two tires, avoiding accidents and helping back parking and driving. The system may work in automatic or manual mode.

An oscillation-type vehicle includes a front vehicle body that suspends a front wheel in a steerable manner, a rear vehicle body that suspends left and right drive wheels, and an oscillation mechanism that causes the front vehicle body and the rear vehicle body to oscillate relative to each other. The oscillation-type vehicle being capable of carrying out drive control of the left and right drive wheels such that the drive wheels behave differently from each other in response to oscillation of the oscillation-type vehicle, wherein the drive control of the left and right drive wheels is carried out using information on the oscillation and information on a speed of vehicle.

A vehicle includes a chassis, tractive elements coupled to the chassis, an electric motor coupled to the chassis and coupled to the tractive elements such that the electric motor drives the tractive elements to propel the vehicle, an accessory module coupled to the chassis and coupled to an output of the electric motor. The accessory module is configured to receive mechanical energy provided by the electric motor and provide at least one of electrical energy or fluid energy.

An electric self-traveling trailer capable of performing automatic following traveling to a towing vehicle without mechanical connection, includes a detection unit configured to detect a peripheral situation, a recognition unit configured to recognize a parking space based on a detection result of the detection unit, a moving control unit configured to move the trailer to the parking space, and an instruction unit configured to transmit, to the towing vehicle, a following instruction for making the towing vehicle follow the trailer moving to the parking space.

An exemplary vehicle assembly includes, among other things, inner and outer panels of a cargo bed, and a heat exchange module that manages thermal energy levels of a traction battery. The heat exchange module is disposed within a chamber between the inner and outer panels. An exemplary thermal management method includes, among other things, managing thermal energy within a traction battery by exchanging thermal energy between a first fluid and a second fluid at a heat exchange module. The heat exchange module is disposed within a chamber between inner and outer panels of a cargo bed.

A tractor trailer battery system having a battery compartment containing one or more battery units which house one or more battery cells, electrical leads from the battery units to a trailer mounted controller in electrical communication with a cab mounted controller which is in electrical communication an electric motor or hybrid engine system. The battery system allows for either the trailer mounted controller or the cab mounted controller to provide principal communication to the electric motor or hybrid engine system.
