This report will cover Bosch, Denso, Aisin, and Mitsubishi Electric's exhibitions, which prominently featured exhibits related to these three fields. Major displays included EV drive systems such as the eAxle, motors and inverters relating to electrification, positioning systems and vehicle control systems for autonomous driving, services utilizing over-the-air (OTA) updates and V2X, as well as numerous products and technology like next-generation human machine interface (HMI) for connectivity. Major exhibitions are listed in the following chart.

There is a global trend towards adopting EVs that is being lead primarily by Europe and China. As can be seen from their exhibitions, Japanese OEMs, which lead the market with hybrid vehicles (HVs), are rapidly preparing to support EVs in anticipation of various future changes in the market.

Because of the difficulty in realizing autonomous driving and connectivity through developing products and services alone, various companies are now collaborating with domestic and overseas companies, including those from different industries, and have been conducting demonstration experiments in collaboration with specialist institutions while also introducing multifaceted initiatives.
