Fundamentals of Unibody Construction - Honda/Acura Collision Safety Technology Compatible (ACE™) Body Features
1. Features of Collision Safety Technology Compatible Body
1.
Increase contact with impact absorption structure of the other vehicle.
The vehicle body is a multi-skeletal structure and is designed with the wheelhouse member positioned outside of front side frame, but joined with large gussets. This mitigates impact with other vehicles in a crash by increasing the area of contact with the other vehicle’s impact absorption structure.
2.
Dissipation of impact load.
By receiving an impact on a wider surface area including the:
Bulkhead upper frame
Wheelhouse member
Front side frame
The impact forces received are more efficiently dissipated through the structure.




3.
Highly efficient absorption of energy.
The optimization of impact absorption parts significantly reduces the load applied to the passenger compartment by improving energy absorption efficiently of the engine compartment.

2. Effectiveness of Crash-Compatibility Body
Effectiveness of Crash-Compatibility Body

In case of a collision between a large-and-small-vehicle, the impact absorption structure allows energy to dissipate in a similar way between those two vehicles. Safety is improved for both of the vehicles.
Crash of Crash-Compatibility Bodies:

Degree of Damage with a Large Vehicle

The frame member will be crushed by the impact through the wheelhouse member and gusset in an offset impact. This mechanism helps decrease the impact against a smaller vehicle.
