Honda Pre-Crash Safety Technology continues to advance based on the concept of assessing collision risk and reducing harm in the event of a crash. Our very first achievements in this field are the CMS (Collision Mitigation brake System) and
E-pretensioner (driver's seat). The system uses millimeter wave radar (employed by HiDS*) to gauge the distance to the vehicle ahead when moving, and estimates relative vehicle speed and other parameters. When the system computer determines a high risk of collision, the system alerts the driver with warnings, and provides brake assistance and seatbelt control to support the driver's hazard avoidance actions and reduce injury should a collision occur.

Alleviating driver fatigue also helps to prevent accidents from occurring. Based on this approach, we developed Honda Intelligent Driver Support (HIDS) aimed at relieving driver stress to reduce fatigue during highway driving. HIDS provides highway driving assistance through a combination of Intelligent Highway Cruise Control (IHCC) - which controls vehicle speed to maintain a safe distance from the vehicle in front - and the Lane-Keeping Assist System (LKAS), which helps to prevent lane departure.

Millimeter radar detects a vehicle ahead when in motion. If the system determines a collision risk as the vehicle ahead is approached, it gives audio and visual warnings.

The system automatically applies light braking and slightly increases seatbelt tension to deliver tactile warning to the driver.

The system automatically applies the brakes and securely tightens the seatbelt to reduce injury caused by impact.

Honda continues to advance its unique G-force Control technology to reduce injuries by controlling the impact-energy of a collision (G). One area of research is crash compatibility, which investigates collisions between vehicles of different size, structure and hardness. This technology both increases self-protection and reduces impact severity on other vehicles in a collision. To successfully achieve these mutually conflicting goals, Honda designed an energy-absorbing car body that efficiently absorbs and disperses crash energy throughout the engine compartment. This crash compatibility body is employed for the first time in the New Life.

Honda developed its side curtain airbag system to more effectively reduce the risk of head injury in a side impact. In the event of a side collision, the system assures protection over a wide area of the head, neck and thorax for passengers of all sizes, from children to adults. Side curtain airbag deployment is of particular benefit in preventing the head impacting with the car's center pillar.
