62-4 SUPPLEMENTAL RESTRAINT SYSTEM - SUPPLEMENTAL RESTRAINT SYSTEM

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
62 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 ≥ 60° to the route.
• 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 ≥ 50° 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.
