Abstract: A control system for a vehicle includes an electronic control unit. The electronic control unit is configured to i) calculate a target supercharging pressure of an intake air such that, when an internal combustion engine is operated through the homogeneous charge compression ignition, the internal combustion engine achieves a required output while satisfying a predetermined requirement, ii) control an output of the internal combustion engine such that the output approaches the required output in accordance with an actual supercharging pressure in process of changing the actual supercharging pressure to the target supercharging pressure that is achieved by a supercharger, and iii) control a rotary machine such that an output of the rotary machine compensates for part or all of a differential output between the required output and the output in process of changing the actual supercharging pressure to the target supercharging pressure.

Abstract: A control apparatus for a hybrid vehicle is provided with: an air-fuel ratio determinator configured to determine an air-fuel ratio of an internal combustion engine in a predetermined period until speed change by a transmission is actually performed; and a controller configured to control at least one of the internal combustion engine and an electric motor in such a manner that a possible amount of torque down of the internal combustion engine is increased if the air-fuel ratio of the internal combustion engine is lean in the predetermined period. By this, it is possible to avoid a detrimental effect, such as a torque shock, deterioration of durability of a friction material, and the like, which can occur in the speed change.

Abstract: A vehicle control system for reducing shocks resulting from restarting an engine under EV running mode. The vehicle control system is applied to a vehicle including an engagement device that selectively connect the engine with the powertrain, and a motor adapted to generate a drive force and connected with the powertrain. In the vehicle, a first mode is selected to propel the vehicle by the motor while interrupting the torque transmission between the engine and the powertrain and stopping the engine, and a second mode is selected to propel the vehicle by the motor while allowing the torque transmission between the engine and the powertrain and stopping the engine. The vehicle control system selects the second mode if a control response of at least any of the engagement device and the motor is estimated to be out of a predetermine range when the vehicle is running while stopping the engine.

Abstract: A control system for a hybrid drive unit for avoiding an overcharging and an over discharging of a battery when starting or stopping an engine. The control system selects a speed ratio where an amount of an electric power to be stored into the battery is large or to be discharged from the electric storage device is small if a state of charge of the battery is lower than a first threshold value (at step S4). The control system selects a speed ratio where an amount of an electric power to be discharged from the battery is large or to be stored into the battery is small if a state of charge of the electric storage device is higher than a second threshold value (at step S7).

Abstract: The electric vehicle according to the present disclosure calculates motor torque using an MT vehicle model simulating an MT vehicle having a manual transmission and an internal combustion engine. In the first operation mode, an operation amount of a pseudo-clutch pedal and a shift position of a pseudo-gearshift are input to the MT vehicle model to reflect operation of the pseudo-clutch pedal and operation of the pseudo-gearshift in electric motor control. In the second operation mode where the operation of the pseudo-clutch pedal is not needed, an operation amount of a clutch pedal calculated by a driver model is input to the MT vehicle model instead of the operation amount of the pseudo-clutch pedal.

Abstract: An electric vehicle includes a shift lever and a clutch pedal for simulating manual gear changes of a traditional vehicle equipped with an internal combustion engine and manual transmission, and includes a controller for controlling the operation of the electric vehicle. The driver operates the shift lever in a similar fashion to that of a traditional manual transmission shift lever, however the associated gear positions do not correspond to physical gears in a transmission but rather virtual gear stage modes that correspond to mapped torque characteristics with respect to the rotational speed of the electric motor. The clutch pedal is operated by the driver when the shift lever is operated. The controller calculates the virtual engine speed of the virtual engine based on the virtual gear stage mode selected by the shift lever and the operation amount of the clutch pedal, and displays the virtual engine speed on a display.
