Weathernews and Toyota Motor are using the operating status of windshield wipers, as well as weather data to ascertain conditions of roads and their surroundings. The companies are carrying out tests in Tokyo, Osaka, and Aichi in Japan.
This is part of a joint research effort to increase the accuracy of weather observation and forecasts, and improve driver safety using Weathernews’ weather data and the vehicle data obtained from Toyota’s connected vehicles.
In this verification test, the wiper operating status of Toyota’s connected vehicles being driven in the designated regions is visualized as a map and compared with actual weather data. Because wiper operating status typically corresponds to the presence or absence of precipitation, using wiper data has the potential to allow detection of precipitation that cannot be detected by standard raincloud radar. In the verification test, the relationship between the wiper data and weather data will be analyzed in detail, with the aim of detecting phenomena that could affect wiper operation in addition to detecting precipitation.
With the launch of the Crown and Corolla Sport in June of last year, Toyota has begun a full-scale rollout of connected vehicles, and going forward, nearly all passenger cars that are launched domestically will have an on-board DCM (Data Communication Module). In addition to its own observation network at approximately 13,000 locations nationwide, Weathernews makes use of 180,000 weather reports a day from users to provide highly accurate weather forecasts.
Through this joint research project, both companies will provide weather data and the vehicle data obtained from connected vehicles as information “that is useful during emergencies” on a broad basis, with the goal of contributing to improved driver safety.
