Event data recorders to be mandatory for new cars
The transport ministry is planning to require new vehicles to be equipped with an event data recorder, or EDR, a device that records in detail the driver’s use of the gas and brake pedals, The Yomiuri Shimbun has learned.
The relevant provisions of the Road Transport Vehicle Law will be revised as early as this fall.
Mandating the installation of an EDR will make it easier to verify whether driver error or vehicle malfunction was the cause of an accident.
The requirement would go into effect from July 2022.
An EDR records how hard and long a driver steps on the gas and the brake. The device can detect less than a second of pressure on a pedal and also notes whether a seatbelt was worn.
Drive recorders, in contrast, keep records through video footage and audio recordings. It is difficult to verify with a drive recorder whether a driver stepped on the gas or brake.
A passenger car went out of control in the Ikebukuro district of Tokyo in April 2019, killing a woman and her child.
At the ensuing trial, a major point of contention was whether the driver of the car — a former head of the now-defunct Industrial Science and Technology Agency, under what is now the Economy, Trade and
Industry Ministry — was at fault.
EDR records were submitted as evidence.
Although EDRs have been installed in many new cars sold in the last few years, only about half of the cars in Japan are currently equipped with one, according to Bosch, a major German auto parts manufacturer.
Following a spate of incidents that appear to have been caused by drivers mistakenly stepping on the gas, the Land, Infrastructure, Transport and Tourism Ministry has decided that increasing the installation of EDRs by making it compulsory is essential to verify the cause of accidents.
The device itself is about the size of a lunch box and is installed near the gear stick.
It can cost tens of thousands of yen to retrieve the records for verification.
The transport ministry will also require systems to detect other vehicles and pedestrians, in tandem with the spread of EDRs.
From November, new models will be equipped with automatic emergency braking systems with vehicle and pedestrian detection that is able to detect people at least 115 centimeters tall, the equivalent of a 6-year-old, during the day.
The ministry is planning to require that the system be able to detect cars and pedestrians at night as well.
From July 2024, the ministry is also expected to require that such systems be able to detect bicycles during the day. (July 4)
