METHOD OF DETECTING NORMALITY OF PWM SIGNAL OF AIRBAG CONTROLLER
A method of detecting normality of a PWM signal, wherein an error in a pulse-width modulation (PWM) signal is detected using four different self-test logics, and information obtained by categorizing results of detection into failure modes is transmitted to a vehicle component controller, so that the consistency of the PWM signal is determined, a signal safety means is secured, and further, safety standard requirements of the automobile field are satisfied.
Enhanced discrimination method and apparatus for controlling an actuatable restraining device
A method for controlling an actuatable restraining device includes sensing a plurality of crash event indications in response to a crash event. The method also includes classifying the crash event in response to comparing the sensed crash event indications against one another to identify an oblique moving deformable barrier crash event. The method further includes controlling deployment timing of the actuatable restraining device in response to the classification of the crash event.

VEHICLE SYSTEM
A safety standard of a predetermined level is set for a function to be implemented in each of devices. A central ECU includes ASIL ECUs to, in which each of the ASIL ECUS to is allocated for each level of the safety standard and is able to execute, on the device, confirmation processing according to the allocated level. A network branch unit distributes and transmits each of input signals from the devices, the input signals being respectively transmitted from zone ECUs, to a corresponding one of the ASIL ECUS each having the level allocated thereto and corresponding to the function of the device, and distributes and transmits each of output signals from the ASIL ECUs, the output signals being respectively transmitted from the ASIL ECUs, to a corresponding one of the zone ECUs each having transmitted the input signal from the device subjected to the confirmation processing.
Method for Transmitting and Receiving a Measured Value of a Sensor
A method for transmitting a measured value of a sensor using a first data word and at least one second data word includes reproducing a first part of the measured value in the first data word and reproducing a remaining part of the measured value in the at least one second data word, such that the reproduced parts of the measured value transition into one another.
