There is provided a hybrid vehicle that enables user to be more appropriately notified of a control effect by performing a drive support control. A hybrid vehicle includes an engine; a motor; a battery; map information; and a control device programmed to set a drive route from a current location to a destination, to create a drive support plan that assigns one of drive modes including a CD mode and a CS mode to each of drive sections of the drive route, and to perform drive support control that causes the hybrid vehicle to be driven along the drive support plan. The control device accumulates control effect obtained by performing the drive support control and notifies the control effect when the hybrid vehicle reaches the destination. The control device deletes the control effect when the predetermined deletion condition is satisfied.

An ECU performs a process including: when a vehicle establishes a Ready-On state, selecting a CD mode; when discharging power is uncompleted and a scheduled time to return the vehicle is a time within a discharging period, setting a second target SOC as a mode switching value; and when the vehicle's power storage device has an SOC reaching the mode switching value and a surcharge imposed on a rental fee is unaccepted, switching the current control mode from the CD mode to a CS mode.

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 truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, 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.
