摘要： To improve accuracy in misfire determination, a control apparatus for an internal combustion engine that controls an internal combustion engine having a variable compression ratio mechanism capable of changing the compression ratio of the internal combustion engine includes a controller configured to: determine that a misfire occurs if the magnitude of rotational fluctuation of the internal combustion engine is equal to or larger than a misfire criterion value and to make the misfire criterion value larger during the time in which changing of the compression ratio of the internal combustion engine is in progress than during the time in which the compression ratio is not being changed.

摘要： A control system is applied to an internal combustion engine having a plurality of cylinders, a variable compression ratio changer configured to change the compression ratio of each of the cylinders of the internal combustion engine individually, in-cylinder injection valves that inject fuel into the respective cylinders, and in-passage injection valves each of which injects fuel into an intake passage corresponding to each of the cylinders. To reduce differences in the air-fuel ratio among the cylinders during changing the compression ratio, the control system makes the proportion of the quantity of fuel injected through the in-passage injection valves to the total quantity of fuel injected through the in-cylinder injection valves and the in-passage injection valves larger during the time in which the compression ratios of all the cylinders are being changed than during the time in which the compression ratios of all the cylinders are fixed.

摘要： A drive force control system configured to reduce a total energy consumption of a hybrid vehicle. The drive force control system calculates: an output power of the engine which can optimize a thermal efficiency given that the engine is operated at a best fuel point; and a required electric power to be supplied from a battery or to be generated by a control motor, which can adjust the drive power established by the output power of the engine to the required power. A power exchange between the control motor and the battery is interrupted if the required electric power to be supplied from the electric storage device or to be generated by the control motor is less than a first predetermined electric power.

摘要： A vehicle control system, in which that maintains a reaction force against the backward movement of a vehicle while preventing an overheating of a motor due to phase lock of the motor. When a thermal load on a specific phase of the motor exceeds a threshold value, a controller execute a phase shift control to reduce a thermal load on a specific phase of the motor by changing a rotational angle of the motor, while interrupting torque transmission between the motor and wheels and generating the torque to stop the vehicle by the actuator.
