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.

Control system for hybrid vehicles

A control system for a hybrid vehicle that shift an operating mode to an appropriate mode from a low mode or high mode. The hybrid vehicle comprises a power split mechanism connected to an engine and a first motor. When a required brake torque of a prime mover cannot be achieved during propulsion in an operating mode established by engaging one of clutches while stopping the engine, the control system excites a motoring of the engine by the first motor while maintaining engagement of the clutch engaged to establish the current operating mode.
