@Toyota: Commencement of Demonstration Tests for the Social Implementation of Level 4 Autonomous Driving Trucks- Implementing Comprehensive Demonstration Driving Tests in the Final Fiscal Year of Theme 3 Projects on Shin-Tomei Expressway –

Toyota Tsusho Corporation (“Toyota Tsusho”), Advanced Smart Mobility Co., Ltd. (“Advanced Smart Mobility”), Nippon Koei Co., Ltd. (“Nippon Koei”), and Mizuho Research & Technologies, Ltd. (“Mizuho Research & Technologies”) were contracted by the Ministry of Economy, Trade and Industry (METI) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) in fiscal 2021 to perform the “initiative for the realization of high-performance trucks on expressways (Theme 3)”^*1 of the “Project on Research, Development, Demonstration and Deployment (RDD&D) of Automated Driving toward the Level 4^*2 and its Enhanced Mobility Services (RoAD to the L4).” The four contractors are advancing technological development and environmental preparation for the social implementation of Level 4 autonomous driving trucks.

Starting today, the four contractors, along with four commercial vehicle manufacturers–Isuzu Motors Limited (“Isuzu”), Hino Motors, Ltd. (“Hino”), Mitsubishi Fuso Truck and Bus Corporation (“MFTBC”), and UD Trucks Corporation (“UD Trucks”)–have commenced comprehensive driving tests on the Shin-Tomei Expressway as the culmination of their verification and demonstration efforts. This initiative represents the final year of Theme 3 projects.

To solve social issues such as driver shortages, the four contractors, together with the four commercial vehicle manufacturers, logistics companies, and other related parties, are aiming for the social implementation of autonomous driving trucks on highway(s) from fiscal 2026 onward through a joint public-private effort.

To date, we aims to achieve single-vehicle driverless driving between relay areas, such as logistics facilities around expressways and service areas, and verifies support from external infrastructure equipment, operations such as monitoring and management, and vehicle functions necessary for such operations to develop the environment for the practical implementation of Level 4 autonomous driving trucks.

The previous year’s demonstration tests were conducted between the Surugawan-Numazu service area and Hamamatsu service area on the Shin-Tomei Expressway. We individually confirmed and verified functions such as the automated departure/arrival system (a function that automatically starts and parks the vehicle), the emergency stopping capability (a braking function to stop the vehicle in case of abnormalities), the predictive information support function (a feature that uses information such as broken-down vehicles and fallen objects transmitted from roadside equipment like ITS spots^*3 to assist with lane changes), and remote monitoring functions.

The final fiscal year demonstration test for Theme 3 projects will involve conducting comprehensive driving demonstration tests on the following functions, which have been previously verified individually, on the Shin-Tomei Expressway (Shin-Gotemba IC to Okazaki service area), including the Automated Driving Service Support Road^*4.

・Automated driving (Level 4 driving assumed) on the Automated Driving Service Support Road and Level 2 driving^*5 on other sections
・Automatic merging via automatic departure/arrival and merge assistance at the Surugawan-Numazu service area and the Hamamatsu service area
・Automatic lane changes and speed adjustments supported by roadside equipment providing predictive information
・Evaluation of operational monitoring functions, including emergency responses

*2 A state in which the autonomous driving device replaces all driving operations in a limited area that meets specific driving environment conditions.

*3 Intelligent Transport Systems (ITS) Spot is infrastructure for road-vehicle communication that enables two-way exchange of road traffic information with vehicles. It is an information and communication device installed on roads. Drivers can receive real-time traffic information and safety information.

*4 Road sections equipped to support the driving of automated driving vehicles. Road sensors and communication equipment are utilized on highways and general roads to assist the operation of automated driving vehicles.

*5 Level 2 driving refers to driving based on adaptive cruise control and lane-keeping assistance, where the driver operates the steering wheel and other controls while maintaining full control.

Automated driving (Level 4 driving assumed)” builds upon Level 2 driving by incorporating merging assistance and predictive information support for obstacles ahead, allowing the driver to operate the vehicle in a hands-off state.
