No. 846: Technologies to support automated driving are advancing (July 29, 2014)

Developing technologies to support automated driving is critical to spread automated driving. Hitachi developed a technology to keep the visibility of the mounted camera excellent. The technology gives a warning when camera’s accuracy to recognize the traffic lane deteriorates when dirt blurs the lens or waterdrops mist the lens. It collects enormous amount of pictures to judge the stains of the lens. In the experiment, it successfully gives a warning when the recognition accuracy of the lens goes down to less than 90% of the image given by the rear view camera regardless of weather and regardless of day or night.

Technova, one of the subsidiaries of Aisin, developed a technology that allows quick charging without cable. The technology is helpful to the contactless charging that transmits electricity from coils buried in the road to a travelling EV. It is possible to charge an EV when it stops at a red light and charge an EV by bits while it is traveling. A circuit to increase electric current by reducing voltage is built in the rectifier mounted on the vehicle. With this technology, it is possible to transmit electricity at two times higher voltage. Accordingly, a parked EV in a parking lot can be charged in three to four hours, about half the time required by the charging that uses cables. The demonstrative experiments are under way to make the technology ready in time for the Tokyo Olympics in 2020.
