A method and system for controlling a hybrid vehicle equipped with an air control valve are provided. The method includes collecting road information and determining a number of conversions between an engine operation mode and a motor driving mode based on the collected road information. Further, a degree of flap closing of the air control valve is restricted from being corrected when the predicted number of conversion is less than a predetermined threshold. The air control valve is adjusted for flap displacement upon closing of the flap when the predicted number of conversion is greater than the predetermined threshold and in which the degree of flap closing of the air control valve is corrected based on the detected flap displacement.

A vehicle control apparatus is provided with: a first controlling device that controls an internal combustion engine to switch an air fuel ratio after an air intake quantity of the internal combustion engine increases to a first predetermined quantity in switching the internal combustion engine from a first combustion mode to a second combustion mode, the air fuel ratio in the second combustion mode being larger than that in the first combustion mode; and a second controlling device that controls the internal combustion engine to perform a suppression operation for suppressing a decrease of a rotation number of the internal combustion engine during at least one portion of a predetermined period at which the air intake quantity increases due to the switching from the first combustion mode to the second combustion mode.

An ECU is applied to a hybrid vehicle that is equipped with an internal combustion engine and a second motor-generator, which are configured to output a driving force for running. The hybrid vehicle is configured to run with the internal combustion engine in intermittent operation. Also, the ECU is configured to calculate an amount of dilution water that is mixed into oil in the internal combustion engine to dilute the oil. The ECU is configured to operate the internal combustion engine when the amount of the dilution water becomes larger than a first threshold.

A dual-motor mixed-hybrid powertrain system, by performing pulse modulation control, i.e., series-hybrid intelligent start-stop control or parallel-hybrid intelligent power switching control, on the instantaneous power time-varying functions of an engine and a battery pack, can convert the surface working condition of an analog electric control engine into a simpler line working condition of a digital pulse control (DPC) engine, either a pre-determined high-state line working condition in the high-efficiency combustion area or a pre-determined non-combustion low-state line working condition with zero fuel consumption and zero pollutant emissions multiplexed in time. The traditional fixed one-to-one bidirectional mapping between an engine working condition and a vehicle working condition is converted into a dynamically adjustable many-to-many bidirectional mapping to achieve the full coverage of any overall vehicle working condition, achieving decoupling between a DPC engine working condition and the overall vehicle working condition and decoupling between software and hardware of a hybrid powertrain.

An electronic control unit includes processing circuitry. A hybrid electric vehicle has an electric traveling mode, in which the hybrid electric vehicle travels with a system clutch disengaged and an engine in a stopped state, and a hybrid traveling mode, in which the hybrid electric vehicle travels with the system clutch engaged and engine operating. The processing circuitry is configured to control, when the traveling mode is switched from the electric traveling mode to the hybrid traveling mode, a throttle opening degree of the engine at the time of completion of engagement of the system clutch in accordance with the atmospheric pressure such that a constant intake air amount is obtained regardless of the level of the atmospheric pressure.

A driving force control device for a vehicle is provided, which includes a motor, an engine, and a controller. The controller sets a target torque of the vehicle corresponding to accelerator operation, and distributes a target engine torque according to a distribution rule defined beforehand, based on the target torque of the vehicle, and outputs a control signal corresponding to the target engine torque to the engine. The controller estimates a future amount of intake air to a cylinder based on the target engine torque, and estimates a torque of the engine in the future based on the estimated future amount of intake air. The controller sets a target motor torque based on the estimated torque of the engine so that the target torque of the vehicle is achieved in the future, and outputs a control signal corresponding to the target motor torque to the motor.
