    摘要: In a small electric motor vehicle equipped with an electric motor for driving wheels through a reduction gear mechanism, a first predetermined voltage is immediately applied to the electric motor when a drive-off instruction is generated from vehicle standstill and then the voltage is increased at a predetermined rate until the voltage exceeds a second predetermined voltage, and is then controlled such that the driving speed converges to a desired speed. With this, since the application of the first predetermined voltage slightly rotates the electric motor to take up reduction gear mechanism backlash, shock at drive-off caused by reduction gear mechanism backlash can be reduced or eliminated even when a high-capacity electric motor is used to enhance hill-climbing performance, and smooth drive-off is possible. Furthermore, since the rate of increase/decrease of the driving speed is varied in proportion to the difference between a set speed and a calculated command speed, the driving feel is therefore improved.

    摘要: A wireless AV system includes a central wireless unit, serving as a base device, and a TV main unit. The TV main unit includes an SS transmitter/receiver (T/R) unit, a TV section, a TV microcomputer, and a second SS-CPU. The SS T/R unit receives an MPEG-2 stream and command transmission data both of which are transmitted from an SS T/R unit of the central wireless unit, and decodes the MPEG-2 stream and the command transmission data so received. The TV section displays a video signal and outputs an audio signal. The TV microcomputer controls the TV main unit entirely. The second SS-CPU detects a communication condition between the central wireless unit and the TV main unit according to a received radio wave field intensity and a retransmission request made based on an error rate. The TV microcomputer causes the TV section to OSD-display such reception sensitivity information messages that video and/or audio data has been interrupted, that transmission channels are being switched, that connection are being made, and that the TV main unit is out of communication range, according to the. communication condition so detected. Thus, a user is free from a feeling of discomfort even when a display image is interrupted due to transmission channel switching etc. Thus, user-friendliness can be improved.
