    • A transparent display comprising a transmittance control block and a display block is provided. The transparent display transmits an optical image from a front surface to a back surface. The optical image is projected onto the front surface. A first image is displayed on the transparent display and superimposed onto the optical image. The transmittance control block is mounted to the front surface side. The transmittance control block comprises a guest-host liquid crystal layer and transparent electrodes. The transmittance of the light incident to the guest-host liquid crystal layer is able to be adjusted. The guest-host liquid crystal is mounted between the transparent electrodes. The display block is mounted to the back surface side. The display block comprises an organo-electroluminescence device. The first image is displayed on the display block.

    • Regenerated power fed from a rotary electric machine is immediately reduced where connection between an electric machine and a DC power source is blocked. An inverter control section controls the inverter by controlling an armature current in a two-axis orthogonal coordinate system that rotates in synchronization with the rotary electric machine, the armature current being a vector obtained by synthesizing a field current and a drive current extending along respective axes of the orthogonal coordinate system. If it is determined that connection between the DC power source section and the inverter is in a blocked state, the inverter control section executes zero-torque control in which the inverter is controlled such that torque regenerated by the rotary electric machine becomes zero, and executes high-loss control in which the field current is varied so as to increase the armature current while maintaining a torque command provided in the zero-torque control.
    • 在电机和直流电源之间的连接被阻塞的情况下,从旋转电机馈送的再生电力立即减少。 逆变器控制部通过控制与旋转电机同步旋转的两轴正交坐标系中的电枢电流来控制逆变器,电枢电流是通过合成场电流和沿各轴延伸的驱动电流而获得的矢量 的正交坐标系。 如果确定直流电源部分和逆变器之间的连接处于阻塞状态,则逆变器控制部分执行零转矩控制,其中控制逆变器使得由旋转电机再生的转矩变为零,并执行 励磁电流变化的高损耗控制,以便在维持在零转矩控制中提供的转矩指令的同时增加电枢电流。
