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.

A control unit of a vehicle, which is configure to travel in a first traveling mode in which power outputted from an electric motor according to electric power supplied from a generator and an electric storage device is used and in a second traveling mode in which power outputted from an internal combustion engine and the electric motor according to the electric power supplied from the electric storage device is used, includes: a vehicle speed acquisition unit; a driving force acquisition unit configured to acquire a driving force in the first traveling mode according to a vehicle speed and a driving force in the second traveling mode according to the vehicle speed; and a traveling mode control unit configured to drive the vehicle in the traveling mode capable of obtaining a large driving force at the vehicle speed based on a comparison result of the driving forces.

Since a maximum rotation speed is set to a lower value when a supercharging pressure from a supercharger is high than when the supercharging pressure is low, an engine torque is decreased at a relatively low engine rotation speed and the engine rotation speed is less likely to fall into a high-rotation state. Since the maximum rotation speed is set to a relatively high value when the supercharging pressure is relatively low and the engine rotation speed is less likely to fall into a high-rotation state, the engine torque is not decreased at a relatively high engine rotation speed and power performance can be easily secured. Accordingly, it is possible to curb a decrease in power performance due to a decrease in the engine torque and to prevent the engine rotation speed from falling into a high-rotation state.

An apparatus for controlling an environment-friendly vehicle, a system having the same, and a method thereof are provided. The apparatus includes a processor to perform a control operation to expand an operable area based on a motor efficiency gain and a state of charge (SOC) of a battery in an Homogeneous Charge Compression Ignition (HCCI) operation or a lean burn operation, and a storage to store the motor efficiency gain and the SOC of the battery, which are acquired by the processor.

There is provided a hybrid vehicle to suppress switching between a motor drive and a hybrid drive in a short time. The hybrid vehicle includes an engine, motor, 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. The hybrid vehicle does not perform the drive support control until elapse of a predetermined time period since the system activation or since the termination of the drive support control. This suppresses switching between the motor drive and the hybrid drive in a short time immediately after the system activation or immediately after the termination of the drive support control.

A method for controlling a hybrid vehicle includes an engine, a battery charged with electric power generated by the engine, and a motor as a drive source and having multiple running modes that can be selected through a mode operation. As the running mode, the method for controlling a hybrid vehicle includes a normal mode configured to perform charging of the battery according to a running state; and a charge mode configured to electric power generation by the engine according to a mode operation, the method comprising setting an upper limit of charging electric power based on the generated electric power in the charge mode to be lower than an upper limit of charging electric power based on the generated electric power in the normal 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.

A hybrid vehicle starts execution of temporary increase control that temporarily increases an allowable discharge power that is a maximum power dischargeable from a power storage device, on satisfaction of a predetermined start condition, and terminates execution of the temporary increase control on satisfaction of a predetermined termination condition. When a predetermined stop condition that is different from the predetermined termination condition is satisfied during execution of the temporary increase control, the hybrid vehicle terminates execution of the temporary increase control and prohibits subsequent execution of the temporary increase control until elapse of a first predetermined time. This configuration suppresses frequent repetition of a temporary increase of the allowable discharge power (output limit) of the power storage device such as a battery and its cancellation.

A method for starting a hybrid vehicle 100 comprising an internal combustion engine 301, an electric motor 320 coupled to a driveline of the hybrid vehicle, a traction battery 302 configured to supply energy to the electric motor, and an open clutch 310 decoupling the internal combustion engine from the driveline, the method comprising: determining s503, s505 whether a temperature-dependent parameter associated with the traction battery satisfies a first condition; starting s535 the electric motor; monitoring s541 satisfaction of a second condition while internal combustion engine speed is greater than zero; and attempting s545 to close the clutch to couple the internal combustion engine to the driveline if the second condition is satisfied.

During the execution of the combustion stopping process for continuing the combustion of the remaining cylinders while the combustion of some of the plurality of cylinders provided in the engine is stopped, the first vibration damping process for generating the vibration damping torque in the first rotary electric machine M1 and the second vibration damping process for generating the vibration damping torque in the second rotary electric machine M2 are executed.
