September 12, 2023 Tokyo, Mitsubishi Heavy Industries Machinery Systems Co., Ltd. (MHI-MS), a member of the Mitsubishi Heavy Industries (MHI) Group, has received an order for millimeter wave suppression equipment from the Japan Automobile Research Institute (JARI). ) will be installed in a specific environmental area in Tsukuba City, Ibaraki Prefecture, within the JARI Autonomous Driving Test Center (J Town) (Note 1). This project was awarded through open bidding conducted by JARI to procure equipment. By the end of the year, MHI-MS will design, manufacture, deliver, install, and test a device that suppresses the detection of vehicle-mounted millimeter-wave radars that interfere with test evaluations of structures inside buildings in specific environmental areas. December 2023.
This millimeter wave suppression device will be used for research and development related to “electric vehicle simulation infrastructure,” which is one of the themes of the “Green Innovation Fund Project/Development of in-vehicle computing and simulation technology for energy saving of electric vehicles.” Masu. A project launched by the New Energy and Industrial Technology Development Organization (NEDO). It will be located within the designated environmental zone of J-Town, which was established by JARI in 2016.
Specified environmental areas are indoor facilities. Therefore, in testing and evaluating millimeter wave radars mounted on test vehicles, a problem arises in that radar waves are frequently detected due to reflection of radar waves from structures such as columns and beams. These detections interfere with test evaluation. The Mitsubishi Heavy Industries Group is working on technology to analyze and control the radio wave environment inside buildings in order to evaluate the environmental impact of advanced driver assistance systems (ADAS). By applying these technologies as a millimeter-wave suppression device, it is possible to suppress the occurrence of radar detection that affects test evaluation due to the reflection and scattering of millimeter-waves from structures in specific environmental areas, and achieve more accurate vehicle safety. Performance evaluation becomes possible.
MHI-MS has a rich track record of delivering low-noise aerodynamic wind tunnels (aerodynamic, temperature, ground effect simulation, natural wind simulation), collision test equipment, and vibration test equipment necessary for the development of test pieces for automobiles and aircraft. , driving simulators necessary for the development of automobile occupant safety technology (Note 2), etc. In addition, MHI-MS and other Mitsubishi Heavy Industries Group companies are building indoor comprehensive environmental test facilities that enable high-precision testing of automated driving systems (ADS) in free natural environments and driving conditions.・We are currently developing a verification system. (Note 3) The Mitsubishi Heavy Industries Group will apply the integration technology cultivated through these developments to millimeter wave suppression devices.
The Mitsubishi Heavy Industries Group is working on business development in the “smart infrastructure” field as part of its growth strategy. The Mitsubishi Heavy Industries Group will contribute to the realization of a safe and secure next-generation mobility society by providing products that support the development of automobile OEMs and sensor manufacturers.
