A charge-discharge control system includes an electronic control unit. The electronic control unit is configured to: calculate an excess or shortage of a state of charge of the battery to a target state of charge as a state-of-charge difference; increase an output voltage of an electric power supply device when the shortage of the state of charge is larger than a first prescribed value; decrease the output voltage of the electric power supply device when the excess of the state of charge is larger than a second prescribed value; calculate an amount of change in the output voltage of the electric power supply device per unit time such that the amount of change in the output voltage of the electric power supply device per unit time is smaller when the calculated full charge capacity is low than when the calculated full charge capacity is high.

Charge-discharge control system for vehicle

Hill hold control for a vehicle that is executed in response to idling stop of an engine is cancelled on the condition that a command to restart the engine for recovery from the idling stop is issued and an engine rotation speed is higher than or equal to a predetermined determination value; whereas, cancellation of the hill hold control is prohibited when the engine is in process of being stopped through the idling stop.

Control device and control method for vehicle

A negative pressure sensor abnormality detection apparatus includes a negative pressure sensor that outputs a signal corresponding to a negative pressure that a negative pressure pump generates, the negative pressure assisting a vehicle driver's brake operation; a negative pressure detection part that detects the negative pressure based on the signal that is output by the negative pressure sensor; a number-of-rotations counting part that counts the number of rotations of the negative pressure pump; and an abnormality determination part that determines that the negative pressure sensor is in an abnormal condition if, under a condition where a change in the driver's brake operation falls within a predetermined range, a change in the negative pressure detected by the negative pressure detection part along with an increase in the number of rotations counted by the number-of-rotations counting part is out of a predetermined range.

Negative pressure sensor abnormality detection apparatus, control apparatus for internal combustion engine and control system

A vehicle includes a starter used for starting an engine and including an actuator performing an engagement operation with a pinion gear and a motor rotating the pinion gear that are separately controllable. When starting the engine by the user's key operation, a start request signal caused by the key operation is delayed in a delay circuit to output a control signal for driving the motor. When restarting an engine after the engine is automatically stopped, a malfunction detection unit detects a malfunction in the delay circuit based on a control signal for driving the actuator and the control signal for driving the motor.

Control device for engine, method of controlling engine, engine starting device, and vehicle

A starter includes a pinion gear, an actuator for moving the pinion gear to a position where the pinion gear is engaged with a ring gear in a driven state, and a motor for rotating the pinion gear. An ECU includes a rotation mode in which the motor is driven before the actuator is driven and an engagement mode in which the actuator is driven before the motor is driven. In the engagement mode, the actuator is driven after lapse of a predetermined first time period since a decision to start an engine was made, and the motor is driven after lapse of a second time period longer than the first time period since the decision to start the engine was made. In the rotation mode, the motor is driven after lapse of the second time period since a decision to start the engine was made.

Starter control device, starter control method, and engine starting device

A vehicle control apparatus includes: detecting means () for detecting an open state or closed state of a hood of an engine room of a vehicle; control means () for controlling a power supply to an onboard device each time an input operation is performed on a switch (); and drive control means () for starting or stopping an engine of the vehicle in accordance with whether or not a state of the vehicle satisfies a predetermined condition. The control means stops the power supply to the onboard device if the input operation is performed on the switch when the detecting means detects that the hood is open in a state where the engine has been stopped by the drive control means.

Vehicle control apparatus

A device for starting an engine includes a starter for starting the engine and an ECU. The starter includes a pinion gear for engagement with a ring gear for cranking the engine, an actuator structured to engage the pinion gear with a ring gear, and a motor for rotating the pinion gear. The actuator and the motor can individually be controlled. The ECU has a rotation mode for driving the motor prior to drive of the actuator and an engagement mode for causing the actuator to engage the pinion gear and the ring gear with each other prior to drive of the motor. When a request to start the engine is made, the ECU switches selection between the rotation mode and the engagement mode based on a rotation speed of the engine and a reduction rate in rotation speed of the engine.

Engine starting device and vehicle incorporating the same

An engine is driven by a starter including a pinion gear that can be engaged with a ring gear coupled to a crankshaft; an actuator causing, in a driven state, the pinion gear to be moved to a position where the pinion gear is engaged with the ring gear; and a motor causing the pinion gear to be rotated. The engine is provided with a rotation angle sensor for detecting rotation of the crankshaft. ECU detects the crank angle of the crankshaft based on a signal from the rotation angle sensor after the actuator is driven and the motor is driven.

Control device and control method for engine, engine starting device, and vehicle

When a predetermined stop condition is satisfied, an engine is stopped. When a predetermined start condition is satisfied, a motor in a starter is driven and the engine is started. When a voltage of a battery for supplying electric power to the motor becomes lower than a threshold value while the motor is driven, stoppage of the engine is thereafter restricted. The threshold value increases as an engine rotation speed at the time when the motor is driven increases.

Control device and control method for engine, and vehicle

A starter can independently drive an actuator for moving a pinion gear to a position where the pinion gear is engaged with a ring gear and a motor for rotating the pinion gear. When synchronization between the ring gear and the pinion gear is restricted, a rotation mode in which the pinion gear is rotated before the actuator is driven is restricted.

Control device and control method for starter, and vehicle

A starter includes a pinion gear that can be engaged with a ring gear provided around an outer circumference of a flywheel or a drive plate of an engine, an actuator for moving the pinion gear to a position of engagement with the ring gear in a driven state, a helical spline for rotating the pinion gear in a reverse direction while the pinion gear moves toward the ring gear, and a motor for rotating the pinion gear. The actuator and the motor are individually controlled. After the actuator was driven and before the motor is driven, drive of the actuator is stopped.

Control device and control method of a starter, and engine starting device

An ECU executes a program including the steps of carrying out fluctuation suppression control in a case where a request to start an engine has been made, a rotation mode has been selected, and a motor is being driven and canceling fluctuation suppression control in a case where a full drive mode has been selected and engagement between a pinion gear and a ring gear has been completed.

A starter includes a pinion gear that can be engaged with a ring gear coupled to a crankshaft of an engine, an actuator to move the pinion gear to a position where the pinion gear is engaged with the ring gear in a driven state, and a motor to rotate the pinion gear. When the engine is started in response to a driver's start intention, any mode of an engagement mode in which the actuator causes the pinion gear to engage with the ring gear before the motor is driven and a rotation mode in which the motor is driven before the actuator is driven is selected. When the engine is started not in response to a driver's start intention, the engagement mode is selected.
