Hino Motors Ltd disclosed the safety technologies employed for the 2014 models of its Selega large-size bus and Profia large-size truck at a test-ride event that it organized for the media June 14, 2014.

The biggest change that Hino made for the new models is the automatic braking system-based collision avoidance function added to them. In Japan, it will become obligatory to equip large-size buses and trucks with such a function in November 2014.

For its previous models, Hino realized a "damage reduction braking system" that sounds an alarm when the risk of a collision increases. It reduces vehicle speed if the driver does not try to avoid a collision despite the alarm. However, the company did not define it as a collision avoidance function.

The automatic braking system of the 2014 models, which were released in April 2014, automatically applies the brakes to avoid a collision even when they are traveling at a speed of 80km/h (approx 49.7mph) and there is a vehicle traveling at a speed of 30km/h (approx 18.6mph) ahead of them.

In Europe, it became obligatory to equip large-size buses and trucks with an automatic braking system in November 2013. And the system is required to avoid a collision when the relative speed is 50km/h. Hino employed the collision avoidance function because this norm will be introduced in Japan in November 2014.
