The transport ministry will introduce a system from April to certify the effectiveness of automatic brake systems that are included in the majority of new cars.

Customers will be empowered to judge a car’s safety easily with an official endorsement for vehicles that have passed certain conditions.

Automatic brake systems were installed in two-thirds or 66.2 percent of standard vehicles produced in 2016, demonstrating the swift pace at which the technology has spread. However, no official system to guarantee their effectiveness has been introduced to date.

Currently, each car maker “self-designates” the effectiveness of their own automatic braking systems, making it hard for customers to scrutinize the differences between the products.

For official certification to be given, the ministry will require cars to meet three conditions. The first is that speed at collisions is reduced to 20 kilometers per hour or less when a moving car approaches a stationary vehicle at 50 kph.

The second condition is when a car driving at 50 kph approaches another vehicle running at 20 kph, a collision is prevented. The third is that drivers are warned by a noise or other means 0.8 seconds before the automatic brake is operated.

Vehicles that pass the three conditions will be publicized on the ministry’s website, and car makers can use the certification in their advertisements.
