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. The electric vehicle also includes a pedal reaction force generator that generates a pedal reaction force in response to the operation of the pseudo-clutch pedal using by the operating of the reaction force actuator. The controller is configured to store the pedal reaction force characteristic simulating the characteristic of the pedal reaction force according to the operation of the clutch pedal. Then, the controller is configured to control the pedal reaction force output by the pedal reaction force generator in response to the operation of the pseudo-clutch pedal using the stored pedal reaction force characteristic.

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: 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: A controller is configured to obtain a speed ratio equivalent value that is determined by a speed ratio set in a transmission unit, and is configured to control an engine by setting an operating point of the engine such that the operating point in the case where a lockup clutch is engaged and the speed ratio equivalent value is large is lower in an output rotation speed for a predetermined output torque than the operating point in the case where the lockup clutch is engaged and the speed ratio equivalent value is smaller than the large speed ratio equivalent value.

Abstract: A vibration damper that effectively damps vibrations moving a drive unit and a support body closer to and away from each other by a rolling mass. The vibration damper comprises: an elastic member interposed between the drive unit and the support body; an arm extending from the drive unit toward the support body; a rolling mass rolled on the arm by a reciprocation of the arm; a support member fixed to the support body while rotatably supporting the rolling mass; and a position changer that changes a contact point between the rolling mass and the arm by reciprocating the arm.

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 torsional vibration damper having improved durability, whose vibration damping performance is ensured irrespective of machining error. The torsional vibration damper comprises: a rotary member rotated by torque; a retainer formed on the rotary member to protrude radially outwardly; a rolling member held in the retainer while being allowed to reciprocate in the retainer; and an inertia body arranged around the rotary member while being allowed to rotate relatively to the rotary member. An elastic member is arranged on any one of inner surfaces of the retainer to push a shaft of the rolling member toward the other one of the inner surfaces of the retainer.

Abstract: A pendulum vibration damper in which a retainer is prevented from being moved or tilted in an axial direction. In the pendulum vibration damper, a restriction member formed on any one of the retainer and an inner face of the casing to be brought into contact to the other one of the retainer and the inner face of the casing when the retainer is moved or tilted in an axial direction of the rotary disc. A clearance between the casing and the rolling mass in the axial direction is shorter than a thickness of the retainer in the axial direction.

Abstract: A control system for an electric vehicle configured to simulate an engine stall which might occur in conventional vehicles while preventing the simulation of the engine stall in an unfavorable situation. A controller of the control system is configured to: execute an engine stall control to simulate a behavior of the conventional vehicle in a situation where an engine stall occurs by stopping a motor, when a virtual engine speed calculated by a virtual engine speed calculator falls below a predetermined speed; and execute a hold assist control to apply a brake torque to the wheel by the brake device upon execution of the engine stall control.
