Automotive MEMS sensors
MEMS sensors (micro electro-mechanical systems) are a key technology for the mobile and connected world.
MEMS sensor applications
In 1995, the start of large scale production at Bosch was laid as the foundation for modern technology. Bosch is a pioneer and the world's leading supplier of MEMS sensors in the automotive and consumer electronics industry. Due to this extensive system know-how, we can design MEMS technology for our customers to fit optimally to the respective application – often even beyond customer specifications.
Bosch Automotive Electronics provides MEMS sensors for a wide range of automotive applications.
Vehicle comfort systems
Vehicle comfort features such as navigation, tilt or inclination measurement, telematics systems, car key modules, car alarm or eCall systems are a rapidly growing field of application for MEMS sensors.
Typically, the required performance level for these MEMS sensors is lower when compared to sensors for sophisticated safety applications like airbag or vehicle stability systems.
Engine management systems
Bosch MEMS sensors for engine management are designed to measure the current ambient pressure accurately and with low drift. Based on the sensor measurement data, the engine management system can supply the combustion engine with the optimum air-fuel mixture, irrespective of whether the vehicle is travelling along a coastal road or a road up in the mountains. As a result, efficiency is improved and consumption is reduced.
Seat comfort systems
Bosch barometric pressure sensors are a key component for pneumatic seat applications. The sensor regulates the correct inflation of the air chambers in multi-contoured seats and ensures that the seat adapts to the anatomy and the individual requirements of the driver and front-seat passenger. Thus, form-adjustable lumbar support as well as adjustable side bolsters on the backrest and seat area stabilize the vehicle occupants. A massage function can also be realized.
Particularly when driving on winding roads and on long trips, the barometric pressure sensors provide increased comfort and help reduce driver fatigue.
