EKP regulation and fuel cut-out in the event of a crash, are ISIS
(Intelligent Safety Integration System) features.
The fuel requirement is transmitted by the DME via the PT CAN
bus and the
byteflight bus to the right-hand side satellite B-pillar
(SBSR).
The EKP regulation is integrated in the SBSR (right-hand side
satellite B-pillar). (The SBSR controls the front right belt force
limiter and the fuel pump.)
The SBSR controls the EKP via a PWM signal in accordance
with the fuel quantity required by the engine.
The current pump speed is recorded in the SBSR from the EKP
current consumption and the fuel quantity required is deduced
from that.
The fuel quantity required is then set from the coded mapping in
the SBSR, after correction according to the pump speed (PWM
control current).
