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.

A control apparatus for a drive-force transmitting apparatus that defines a first drive-force transmitting path that is to be established by engagements of a first frictional engagement device and a dog clutch and a second drive-force transmitting path in which a lower gear ratio is provided than in the first drive-force transmitting path. In a second running mode with the second drive-force transmitting path being established, the control apparatus places the dog clutch in a released state when a vehicle running speed is higher than a first speed value, and places the dog clutch in an engaged state when the running speed is not higher than the first speed value. Further, in the second running mode, the control apparatus inhibits the dog clutch from being switched to the released state when an accumulated heat quantity in a synchromesh mechanism of the dog clutch is larger than a first quantity value.

A control method for an electric vehicle controls braking force when the accelerator operation amount is less than a prescribed value and controls drive force when the accelerator operation amount is at least a prescribed value. The electric vehicle control method estimates disturbance torque that acts on the motor as a resistance component relating to gradient; and executes correction whereby the braking force or the drive force is increased/decreased on the basis of the disturbance torque estimated value, such that the resistance component is negated. A determination is made regarding whether or not the accelerator operation amount is a partial equivalent amount and, if at least either the accelerator operation amount on a downhill road is greater than the partial equivalent amount or the accelerator operation amount on an uphill road is less than the partial equivalent amount, the correction amount is reduced.

In one aspect, a controller for driving a motor of the present invention includes a driving control unit that controls driving of a motor, and a regenerative control unit that instructs the driving control unit to start regeneration when a signal from a pedal rotation sensor that detects a rotation direction of the pedal indicates that the rotation direction of the pedal is backwards, the regenerative control unit controlling an amount of the regeneration in accordance with a backward rotation amount of the pedal while the rotation direction of the pedal is backwards, the backward rotation amount being obtained by the pedal rotation sensor.
