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 controller of the electric vehicle is configured to control the torque of the electric motor using the MT vehicle model based on the operation amount of the accelerator pedal, the operation amount of the pseudo-clutch pedal, and the shift position of the pseudo-shifter. Further, the controller is configured to execute the stall production process for changing the engine output torque used for calculation of the driving wheel torque to zero when the calculated virtual engine speed using the MT vehicle model becomes lower than the prescribed stall engine speed.

Abstract: A control device for a power transmission mechanism includes a controller. The power transmission mechanism includes an engagement mechanism and an operation mechanism including a movable member and a guide member. The guide member includes a plurality of guide areas being configured to move relative to the movable member to guide the movable member to an engaging position or to a disengaging position. The controller is configured to switch, when determining that a predetermined condition related to traveling of the vehicle is satisfied, a contact guide area that is in contact with the movable member to guide the movable member to the engaging position or to the disengaging position, from a first guide area to a second guide area that are included in the plurality of guide areas.

Abstract: A control system for a power transmission unit configured to shift an operating mode smoothly by manipulating engagement devices, and to simplify a structure of the power transmission unit. The control system is configured to reduce a speed difference between an axially stationary engagement element and a reciprocatable engagement element of a second engagement device when shifting from a first continuously variable mode to a second continuously variable mode by engaging the second engagement device. After the second engagement device has been engaged completely, a first engagement device is disengaged.

Abstract: A shifting device in which a selected shift position can be confirmed easily, and which can be fitted easily in vehicles. The shifting device comprises: a restriction member that restricts a movement of a shift lever into a predetermined shift slot in a first shifting mode, and that cancels the restriction of the movement of the shift lever in a second shifting mode; and an indicator that indicates a first pattern when the first shifting mode is selected, and that indicates a second pattern when the second shifting mode is selected.

Abstract: A shifting mechanism in which an inclination of a sleeve with respect to a shift fork is reduced while maintaining a clearance between the shift fork and the sleeve. In the shifting mechanism, an engagement groove is formed entirely around a shift sleeve, and a cutout is formed on the engagement groove. A first diameter of the shift sleeve between predetermined sites of the bottom of the engagement groove within the cutouts is shorter than a second diameter of the shift sleeve between predetermined sites of the bottom of the engagement groove. A straight-line distance between the engagement ridges formed on both ends of the shift fork is longer than the first diameter but shorter than the second diameter.

Abstract: A power transmission unit that can prevent unintentional disengagement of a clutch. A first set of teeth formed on an outer circumferential surface of a first rotary member is engaged with a third set of teeth formed on an inner circumferential surface of a second rotary member. A second set of teeth formed on an inner circumferential surface of the first rotary member is meshed with a fourth set of teeth formed on an outer circumferential surface of a third rotary member. A center of engagement between the first set of teeth and the third set of teeth is situated at a point withdrawn from a center of engagement between the second set of teeth and the fourth set of teeth in the direction to disengage the first set of teeth from the third set of teeth.

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 battery electric vehicle includes an accelerator pedal, a shifter, a mode selector, and a control device. The mode selector selects either an EV mode or an MT mode as a control mode for an electric motor according to a mode selection operation by a driver. When the SOC of a battery is within a predetermined range, the control device controls the electric motor in the control mode selected by the mode selector. When the SOC is out of the predetermined range, the control device controls the electric motor in the EV mode regardless of the control mode selected by the mode selector.
