 This report summarizes lectures and exhibits regarding Advanced Driver Assistance System (ADAS) technologies that were presented by Bosch, Denso and Renesas Electronics at the 2015 International Automotive Electronics Technology Expo held on January 14 to 16, 2015.

 The three companies plan to improve their safety and driver assistance technologies and commercialize new technologies in phases while looking ahead to achieving autonomous driving in the future.

 Bosch suggested two approaches with the understanding that automated driving starts with highway driving and parking assist functions. According to Bosch, autonomous driving would require "surround sensing technology," "safety and security technology" and "legislation." The company introduced map data and system architecture including electrification that supports the automation technologies.

 Denso gave lectures on its recognition (surround sensing) technology. The company plans to rely on a signal processing technology called Multiple Signal Classification (MUSIC) and scanning type Light Detection and Ranging (LIDAR) that help increase the accuracy of recognition. Denso also introduced plans to use quasi-zenith satellites to increase the accuracy of positioning a vehicle to the level of 10cm.

 Renesas Electronics Corporation, a semiconductor manufacturer, outlined the latest trends in the development of autonomous driving technology. Driving safety and other driver assistance technologies have become highly advanced, more objects can be detected and recognized, and the recognition speed has increased as has the power consumption of associated devices. As a result, the automobile industry is facing a stricter demand for functional safety than before. Renesas Electronics has developed the "R-Car" which is an ADAS-compliant system-on-a chip (SoC: a system LSI), and RH850 Series of 32-bit microcontrollers that provide all-in-one solution for driver assistance systems. These devices have been developed to reduce power consumption of such systems. Renesas Electronics has also developed Wireless Access in-Vehicle Environment (WAVE), a new communication solution under the "Connected Car" approach.
