Toyota Research Institute’s Platform 4 (P4) automated driving test vehicle will be available for public demonstration rides next summer in Tokyo.

Offered from July to September, 2020, the P4 will demonstrate Toyota’s ‘Chauffeur’ SAE Level-4 capabilities in a specific ‘mobility as a service’ (MaaS) driving environment.

The P4 experience will take place in Tokyo’s Odaiba district, a busy and often congested waterfront sub-centre. Odaiba’s complex environment of pedestrians, vehicle traffic, diverse road infrastructure and tall glass buildings provide a challenging setting in which to demonstrate the capabilities of Toyota’s automated driving technology.

The public will be invited to register for the experience and individuals will be selected to participate. In accordance with Japanese law, a safety driver will be present during the experience.

“By challenging ourselves to successfully operate autonomously in Odaiba, we have set a high bar that requires us to rapidly expand the capabilities of our technology in a short amount of time,” said TRI CEO, Gill Pratt.  

“To accomplish that, we are working closely with the Advanced R&D Division of Toyota Motor Corporation and Toyota Research Institute-Advanced Development (TRI-AD) based in Tokyo, who is responsible for bringing the P4’s automated driving software to the public.”

TRI has been testing the P4 in the US at its Ottawa Lake, Michigan, closed-course test facility. TRI replicated Odaiba’s most challenging infrastructure characteristics and driving scenarios for which the P4 will have to navigate autonomously.

Further testing of P4 software is being conducted on public roads in Odaiba and around TRI’s Ann Arbor and Los Altos, California research offices.

Introduced at CES 2019, the P4 test vehicle is based on the fifth-generation Lexus LS sedan.

It is being used in TRI’s research and development of both Toyota Guardian active safety and Chauffeur automated driving applications.
