摘要： A hybrid vehicle includes an engine, a motor generator, a main battery, a DC-DC converter, a sub-battery, a starter, and an electronic control unit. The DC-DC converter is a bidirectional converter configured to convert a voltage of electric power from the sub-battery and output the electric power to the motor generator. The electronic control unit is configured to control the DC-DC converter such that the sub-battery outputs electric power to the motor generator when a first available electrical energy of the main battery is smaller than a required electrical energy at the time when the engine is started with the use of the motor generator.

摘要： When an engine is stopped, a rotational position at a time when a crankshaft starts rotating in a reverse direction is predicted based on a rotational position detected by a crank angle sensor. A target rotational position is set within a range of the crankshaft rotational position between a time when the exhaust valve of one of four cylinders in the expansion stroke when the crankshaft starts rotating in the reverse direction is opened and a time when the expansion stroke of the cylinder ends. When the predicted rotational position is behind the target rotational position, a torque applying device applies a positive rotational torque to the crankshaft. At the time when the exhaust valve of the cylinder in the expansion stroke when the crankshaft starts rotating in the reverse direction is opened, application of the positive rotational torque from the torque applying device to the crankshaft is stopped.

摘要： A drive control section automatically stops an engine by stopping fuel injection and by closing a throttle valve that adjusts the amount of intake air when a predetermined specified condition is satisfied. A stopping-angle detection section detects a crank angle when the engine is automatically stopped as a stopping angle. The drive control section cranks the engine before an in-cylinder negative pressure period, in which pressure in a cylinder of the engine is negative pressure, elapses after starting to automatically stop the engine if the stopping angle is outside an allowable crank-angle range in which it is possible to restart the engine by cranking the engine by the motor generator.

摘要： A control apparatus includes a diesel engine having a throttle valve and a fuel injection valve, an electric driving machine that assists in drive of the engine, and a controller configured to stop the engine automatically when a first condition for automatically stopping the engine is established during an operation of the engine. At this time, the controller is configured to operate the throttle valve to a closing side in response to establishment of a second condition that is established prior to establishment of the first condition, and stop supply of fuel by the fuel injection valve in response to subsequent establishment of the first condition.

摘要： A motor control system includes an MG, a battery, an SMR, and an MG-ECU. The MG-ECU is configured to control the MG in accordance with an instruction provided through communication. The MG-ECU is configured to execute autonomous power generation control of the MG in an event of a fault in the communication. The autonomous power generation control is control in which the MG-ECU causes the MG to generate a predetermined voltage not in accordance with the instruction. The MG-ECU is configured to, when a fault is detected in the communication, start the autonomous power generation control after the SMR has finished switching from an off state to an on state.

摘要： When a start condition is satisfied after the internal combustion engine has been stopped according to an automatic stop control, a control apparatus reversely rotates the engine to compress an air in an expansion stroke cylinder at that time point, and thereafter generates a first time combustion. The apparatus determines whether the start condition becomes satisfied based on a first start request owing to a driving operation by a driver of a vehicle on which the engine is mounted. When the start condition becomes satisfied based on the first start request, the control apparatus makes a maximum value of an engine generating torque by the first time combustion and/or a maximum torque of the engine generating torque by a second time combustion larger as compared to when the start condition becomes satisfied based on a second start request other than the first start request.

摘要： A control device is applied to a hybrid vehicle (1A) in which an internal combustion engine (2) and an MG (3) are connected through a second clutch (21), the MG (3) and a transmission (10) are connected through a first clutch (20) whose state is switchable by a depression operation of a clutch pedal (CP), and an output shaft (12) of the transmission (10) is connected to a driving wheel (5) so as to transmit power. The control device starts the internal combustion engine (2) when an accelerator opening is equal to or greater than a start determination value. When the vehicle (1A) is stopped and the internal combustion engine (2) is stopped, and when the amount of return of the clutch pedal (CP) is small, the control device makes the start determination value greater than when the amount of return of the clutch pedal (CP) is great.
