  • Publication number: 20250058646
    Abstract: The present disclosure provides a battery electric vehicle enables the driver to recognize whether the vehicle is driven in a motor driving mode or in a variable speed driving mode. The controller is programmed to control the display apparatus to display simulated rotation speed as rotation speed of the engine in the engine vehicle with simulated torque behavior when the variable speed driving mode is selected by the mode selector, and not to display the simulated rotation speed when the motor driving mode is selected by the mode selector. This enables the driver to recognize whether the vehicle is driven in the motor driving mode or in the variable speed driving mode.

  • Publication number: 20240317073
    Abstract: A battery electric vehicle includes: a mode selection device in which one travel mode is selected from a plurality of travel modes by an operation of a driver, the travel modes including a motor travel mode in which a motor is controlled such that required torque required for traveling is output to a drive shaft, and a shift travel mode in which the motor is controlled such that torque output to the drive shaft based on a shift operation by the driver is simulation torque that simulates torque behavior in an engine vehicle equipped with an engine and a stepped transmission; and a control device that controls the motor such that the battery electric vehicle travels in the travel mode selected by the mode selection device. The control device prohibits a change in the simulation torque while the battery electric vehicle is traveling, when the shift travel mode is selected.

  • Publication number: 20240253476
    Abstract: A battery electric vehicle includes: an accelerator pedal; a shifter; a mode selection device that selects a control mode for an electric motor from a manual mode and an automatic mode in accordance with a mode selection operation by a driver; and a motor control device. The motor control device varies an output characteristic of the electric motor for an operation of the accelerator pedal in accordance with an operation position of the shifter in the manual mode. The motor control device varies an output of the electric motor in accordance with the operation of the accelerator pedal, irrespective of the operation position of the shifter, in the automatic mode. When ACC is requested during control in the manual mode, the motor control device switches control for the electric motor from the manual mode to the automatic mode.

  • Publication number: 20240208359
    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.

  • Publication number: 20220395939
    Abstract: The diaphragm boss is fixed such that the shaft part and the enlarged-diameter part are exposed upwardly. The diaphragm member is held with an air suction force by a robot arm apparatus having an air suction part such that the small-diameter concave part and the large-diameter concave part are exposed downwardly. By controlling the robot arm apparatus, the diaphragm member is brought into contact with the diaphragm boss while tilting an axis of the diaphragm member with respect to an axis of the diaphragm boss. By controlling the robot arm apparatus, the small-diameter concave part and/or the large-diameter concave part of the diaphragm member are pressed against the diaphragm boss while rotating the diaphragm member around the axis of he diaphragm boss, so that the enlarged-diameter part is fitted into the large-diameter concave part and the shaft part is fitted into the small-diameter concave part.
