Abstract: A control device performs a control process such that when there is a request in a series/parallel mode to switch the current mode to a parallel mode, and the current speed ratio also has a value faster than a Lo rotation synchronization speed ratio, the control device performs the step of switching the running mode to the parallel mode via a series mode with asynchronous switching, whereas when the current speed ratio has a value slower than the Lo rotation synchronization speed ratio, the control device performs the step of switching the running mode to the parallel mode via the series mode with synchronous switching.

Abstract: A drive force control system for a vehicle configured to accurately imitate a change in a drive force in a model vehicle. A drive torque simulator computes a virtual drive torque supposed to be delivered to drive wheels of the model vehicle in response to a manual operation to manipulate the vehicle, based on torque changing factors of a powertrain of the model vehicle. An actual torque calculator computes a target torque of a motor that is practically delivered to the drive wheels in the vehicle based on the virtual drive torque computed by the drive torque simulator, taking account of torque changing factors of the powertrain of the vehicle.

Abstract: A vehicle driving apparatus includes: an engine; first and second rotary electric machines; a fluid transmission device including an input-side rotary element to which the engine and the first rotary electric machine are connected; and a control device configured to control an operation point of the engine by adjusting an electrical path amount in an electrical path between the first and second rotary electric machines. When a certain running mode is established, the control device is configured to correct the electrical path amount to an increased electrical path amount while maintaining an power of the engine requested by an operation of a vehicle driver, and to drive the second rotary electric machine, while controlling an output torque of the first rotary electric machine such that the electrical path amount transferred from the first rotary electric machine to the second rotary electric machine becomes the increased electrical path amount.

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.

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: The electric vehicle according to the present disclosure is configured to be able to select a traveling mode between an MT mode in which an electric motor is controlled with torque characteristics like an MT vehicle having a manual transmission and an internal combustion engine, and an EV mode in which the electric motor is controlled with normal torque characteristics. The controller of the electric vehicle controls the electric motor in the MT mode such that responsiveness of the motor torque with respect to a change in the operation amount of the accelerator pedal is lower than in the EV mode.

Abstract: A driving force control system for a hybrid vehicle is provided to reduce a shock resulting from switching a travelling direction between the forward direction and the backward direction. The control system is applied to a hybrid vehicle in which an operating mode can be selected at least from a series mode and a series parallel mode. A travelling direction of the vehicle is switched by a shifting device between forward direction and backward direction. A controller is configured to maintain the previous operating mode after switching the travelling direction of the vehicle by the shifting device.
