Infineon Launches Two New XENSIV™ Air Pressure Sensors for Engine Management and Pneumatic Seating Systems

【Lansheng Technology Information】Infineon Technologies has launched two new XENSIV™ barometric pressure (BAP) sensors for automotive applications: KP464 and KP466. KP464 is mainly designed for engine control management, and KP466 BAP sensor is mainly used for seat comfort functions.

KP464 helps improve fuel efficiency and reduce power consumption

The KP464 BAP sensor is capable of measuring barometric pressure, which depends on altitude and weather conditions. The engine management system can use the measurement data of this sensor to calculate the air density and ensure an optimal air-fuel ratio. This is a key feature for improved fuel efficiency and reduced power consumption. Along with reduced energy losses, emissions of carbon dioxide and other pollutants are also minimized. Infineon's KP464 BAP sensor combines diagnostic functions such as density measurement and manifold air pressure monitoring. Lower power consumption and miniaturization of the package can improve the production efficiency of the device.

KP466 helps improve comfort and bring more technical advantages

Infineon's new generation KP466 BAP sensor enables seat manufacturers to realize innovative pneumatic seating systems with numerous additional functions. These features not only increase comfort, but also provide significant technical advantages. For example, the multi-contour seat function enables the occupant to adjust the seat contour according to individual needs; the air unit integrated in the lumbar support and seat cushion enables the seat to adapt to the contours of the body; the massage function further improves occupant comfort on long-distance journeys by alternately inflating and deflating the air unit; the driving dynamics function automatically adjusts the side support of the seat according to the current driving situation, providing the occupant with optimal stability in various situations, including cornering.

This optimized solution dramatically reduces power consumption and uses a miniaturized five-hole housing. The system constantly monitors the pressure status and adjusts the saddle pressure according to current requirements. To do this, the system uses multiple absolute pressure sensors to monitor the pressure throughout the system. This Infineon sensor also supports SPI for efficient system communication.
