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.

There is provided a hybrid vehicle to suppress hunting (inversion) of a drive mode in a short time. The hybrid vehicle has an engine, a motor, a battery, an air conditioning system configured to condition air in a passenger compartment, and map information, and sets a drive route from the present location to the destination, and creates a drive support plan in which one of the drive modes including CD mode and CS mode is assigned to each drive section of the drive route to perform the drive support control. The drive support plan is created based on the battery remaining capacity taking into account the power consumption of the air conditioning system. When the predetermined condition that is based on the battery remaining capacity without taking into account the power consumption of the air conditioning system is satisfied while performing the drive support control, the driving state is continued.

An engine control apparatus is applied to a system including rotating electrical machine, a battery connected to the rotating electrical machine via a power conversion circuit, and an electric load. The engine control apparatus determines that engine speed is within a predetermined rotation speed range including at least a resonance range of an engine during a rotation drop period while engine speed drops to zero after engine combustion is stopped, and, in the case where it is determined that engine speed is within predetermined rotation speed range, selectively performs one of first rotation drop processing of increasing reduction rate of engine speed by regenerative power generation of the rotating electrical machine and second rotation drop processing of increasing reduction rate of engine speed by causing rotating electrical machine to perform power driving on an inverse rotation side. At a rotation drop control unit the first rotation drop processing is performed.

A control apparatus is used in an onboard system provided to a vehicle. The onboard system includes an internal combustion engine and a power generator. The power generator generates power and supplies the generated power to an electrical load provided to the vehicle. An output torque of the internal combustion engine causes the vehicle to travel and causes the power generator to generate power. Based on a power supply request by the electrical load, the control apparatus controls the output torque of the internal combustion engine. In response to the output torque being increased based on the power supply request, the control apparatus causes the power generator to generate the power by the output torque, while restricting generated power during an initial period when the output torque is being increased.

A hybrid vehicle includes an electric generator, a drive motor, a power storage device, a power consuming device, and a controller. The controller is configured to control driving of the power consuming device. The controller is configured to execute power consumption increasing control when a vehicle power balance value is larger than a first threshold while the drive motor operates in a braking-period power generation mode.

A system and method of this disclosure control an on/off state of a power take-off by monitoring the power demand of a fluid power circuit that includes the power take-off and a piece of equipment connected to the power take-off. The power demand may be indicated by a pressure or temperature of a fluid power circuit, by a motion of the equipment or its hand-held controller, or by an engine torque of an engine driving the power take-off. When the equipment transitions between an off state and an on state, the controller automatically engages the power take-off. When the equipment is in the on-state for a predetermined amount of time and the power demand is at or below a predetermined threshold during the predetermined amount of timethereby indicating idle time or an inactive state of the equipmentthe controller automatically disengages the power take-off.

Systems and methods for operating a vehicle that includes an engine and an integrated starter/generator are described. In one example, torque generated via the engine is based on a requested driveline torque and a torque of an electric machine when degradation of an engine sensor is present. The torque generated via the engine may be adjusted responsive to a requested engine torque and a feedback engine torque that is based on output of an engine airflow sensor.

A control device of a vehicle including an engine, an auxiliary machine driven by rotation of the engine, and an engagement device selectively connecting and disconnecting a power transmission path between the engine and drive wheels comprises: a coasting control portion for selectively providing a first coasting control for allowing the vehicle to coast with the engine brought into a drive state while the power transmission path is disconnected by release of the engagement device, and a second coasting control for allowing the vehicle to coast with the engine brought into a stop state while the power transmission path is connected. If a load of the auxiliary machine is equal to or greater than a predetermined load and a vehicle speed is equal to or greater than a predetermined vehicle speed when a predetermined coasting start condition is satisfied, the coasting control portion provides the first coasting control.

Disclosed is a vehicle acceleration compensation system, including an accelerator pedal, throttle, and a transmission configured to shift between two or more fixed gears, wherein each gear relates the motor power to a vehicle torque. The system also includes a control unit configured to receive data from one or more sensors. The control unit includes a real-time throttle map relating the accelerator pedal position to the throttle position, such that a given accelerator pedal position directs a corresponding target throttle position, and a real-time shift map relating a desired transmission gear to a current transmission gear, current vehicle speed, and current throttle position, such that a given vehicle speed, given throttle position, and given transmission gear directs a corresponding target transmission gear. In response to sensor data, the control unit updates the throttle map and shift map such that the vehicle torque is altered to produce a desired acceleration value.

A drive force control system for hybrid vehicles to prevent a reduction in drive force during reverse propulsion while operating an engine. An operating mode of a transmission mechanism can be selected from a first mode in which the output torque of the engine is delivered to the output member at a first predetermined ratio and a second mode in which the output torque of the engine is delivered to the output member at a second predetermined ratio that is smaller than the first predetermined ratio. A controller is configured to restrict selection of the first mode when the engine generates a power greater than a predetermined power during propulsion of the hybrid vehicle in the reverse direction.
