The sensor provides a filtered and normalized differential pressure signal ΔP/P0 to the airbag ECU using the wellestablished PSI5 standard current interface. The pressure range of the sensor ...
· The sensors have proven themselves for many years in another safetyrelated automotive application: as a side airbag sensor. KP200: Central component for improved pedestrian protection Infineon offers its KP200 pressure sensor as a central component for automobile safety systems. For the pedestrian protection system that Continental developed together with the vehicle manufacturer, …
· Common pressure sensor measurements in modern vehicles include engine oil pressure, tire pressure, side airbag pressure in crash detection systems, manifold absolute pressure, barometric pressure, seat occupancy pressure and more. What do you think/Comments? Do you have a pressure sensing question? Let me know and we’ll address it in an upcoming blog. – info …
A pressure sensing apparatus for an airbag may include: a sensor element configured to measure a change of air pressure by a vehicle collision; a housing having the sensor element seated therein, including a terminal part electrically connected to the sensor element, and fixed to a vehicle body; a cover detachably installed on the housing; and an elastic pressing part having one side connected ...
Sensors designed for this emerging application are typically compliant with the PSI5 (Peripheral Sensor Interface 5) protocol, which was originally developed as a reliable interface between airbag sensors and ECUs, and uses a twistedpair that carries both power and data. Pressure sensors designed for this safetycritical application operate over a range of around 50 to 110 kPa.
· Airbag sensors are actually small electronic pieces that sense when an accident has taken place. They are designed to respond to circumstances such as increased pressure resulting from a collision and sudden stopping. Airbag sensors can be used to detect how many people are in the vehicle and measure wheel speed, impact and brake pressure.
For the airbag control units, the software functions can be put together in a flexible manner, including, for example, the integration of an occupantclassification system or an electronic pedestrian protection system that uses the data from acceleration sensors or a pressure tube sensor in the bumper. In addition, the airbag control units can be used as an event data recorder, if required.
· Traditional airbag systems have adopted mechanical airbag sensors, such as the mass and roller type sensors. Since the introduction of this technology, there have been applications of more sophisticated sensing systems such as the electronic crash sensors and sensor microsystems. Radar, infrared and image processing are currently implemented to work with a vehicle control unit to …
