SUPPLEMENTAL RESTRAINT SYSTEM - SUPPLEMENTAL RESTRAINT SYSTEM 42-3
SYSTEM PERFORMANCE

1. Airbag
(a). Fuzzy control (critical state).
• If the impact of a head-on collision is less than the case that it drives forward at
the speed of 13 ± 1 km/h and hits a fixed and rigid wall vertical to the route, the
airbag will not be deployed.
• If the impact of a head-on collision is greater than the case that it drives forward
at the speed of 23 ± 1 km/h and hits a fixed and rigid wall vertical to the route,
the airbag must be deployed instantly and reliably.
• If the impact of a head-on collision is between the two cases that it drives forward
at the speed of 13 ± 1 km/h and 23 ± 1 km/h and hits a fixed and rigid wall
vertical to the route respectively, the system is under fuzzy control and it is normal
either it is deployed or not.
(b). In case of a collision described below, the airbag must be deployed instantly
and reliably in order to effectively protect the driver and comply with related laws
and regulations:
• The collision is equivalent to the case that it drives forward at the speed of 50 ± 2
Km/h and hits a fixed and rigid wall vertical to the route.
• The collision is equivalent to the case that it drives forward at the speed of 50 ± 2
Km/h and hits a fixed and rigid column (φ = 250 mm) vertical to the route.
• The collision is equivalent to the case that it drives forward at the speed of 50 ± 2
Km/h and hits a fixed and rigid wall at an angle ≤ 30° to the route. 42
• The collision is equivalent to the case that it drives forward at the speed of 56 ± 2
Km/h and hits a fixed and rigid wall at an angle ≤ 40° to the route.
(c). If the vehicle suffers a collision from the side or rear, it rolls over or there is no head-
on collision, the airbag is designed not to deploy.
(d). If the vehicle suffers a serious collision from beneath, the airbag may probably be
deployed.
