Electronic circuit used to check vehicle safety for research purposes uses acceleration sensors mounted at various locations in vehicle and connected to evaluation circuit

摘要

The sensors are connected to a series data bus (18) with two connections to a sensor bridge (26) and three connections (42,44,46) to an analog-digital converter (40) via a circuit with a programmable read only memory (48). The analog-digital converter is connected to a low-pass filter (38) and a first-stage amplifier (36).
