“…It is difficult to see a direct link between stand-alone failures and system failures The main objective of this work is to create a model which take into account all parameters measured. This full behavioral model will be based on the ESD protection strategy and on failure blocks (FB) that include probability levels of failures as previously studied in [8].…”

Electrical igniters of vehicle occupant restraint systems can be activated by electrical pulses or high frequency currents caused by electromagnetic fields. In order not to perturb unintentional ignition of the propellant charge and a releasing of the Airbags or the seat belt tightener in the vehicle, the igniters are always qualified with special ESD and RF immunity tests in the development process. Protection concepts against ESD may not affect the safe function of the restraint systems in case of a vehicle crash. Simulations make a fast examination of several test concepts possible and allow checking of parametrical influences in detail. A thermal electrical model of an igniter was developed and verified on the basis of laboratory measurements. The calculation results show a good agreement with measurements. Different configurations were examined and fundamental relations were represented.I.

“…This block determining the failure type (Hard or Soft) is activated via the signal "Flag" when the protection is triggered. In the block, the current which passes through the protection (Signal "i(t)") is computed using the formula (1). …”

“…In operating conditions, cars are exposed to external perturbations. As the systems are not directly connected to ground, fast discharge events due to electrostatic accumulations or disconnections of cables can generate Electrical Fast Transient (EFT) perturbations [1]. These perturbations can induce critical faults in the automotive applications, which has impact on the passengers' safety.…”

Microelectronics Reliability, Elsevier, 2017, 76-77, pp.685 -691 AbstractDuring its life, an automotive application can encounter several perturbations such as fast transient of ESD discharges. In this paper, we propose a LIN transceiver behavior model to predict both hard and soft failures within a communication link. The proposed model, extracted from measurements, is implemented into simulation as a failure block. We will show that depending on the output state of the LIN, the data reading behavior could be different. Using such model, corrections at system level can be implemented to avoid failures.
