Inertial sensor features integrated vibration damper for ESP
The new Bosch SMI650 combined inertial sensor is designed to cope with the harsh environment found in a car's engine compartment.
According to the company, it can withstand operating temperatures up to 140°C and is able to deal with even strong broadband vibrations thanks to a special vibration damper.
Bosch claims this is the first time an electronic control unit for the ESP electronic stability programme has featured a sensor with integrated vibration damper.
A biaxial acceleration sensor and a monoaxial yaw sensor together give the SMI650 fully fledged ESP senses for monitoring a vehicle's three axes of motion.
The first series-production version of the new combined inertial sensor will be incorporated in Bosch's current generation 9 ESP electronic control units.
