Bosch launched two acceleration sensors for chassis control

in late February 2011, if the icon flickered, Bosch Group launched smb431 and smb433 two low g-value acceleration sensors for vehicle chassis control applications. This is also the world's first low g-value acceleration sensor that meets the external sensor interface standard psi5 (peripheral sensor interface)

smb431 low G value acceleration sensor is mainly used to record the dynamics of the vehicle's vertical axis, and the measurement range is 1.6 g (here, the g value is calculated according to 1 g = 9.81 m/s2); The smb433 low G acceleration sensor is used to measure the vertical acceleration parameters of the tire, with a measurement range of 16 G. These two micro electro mechanical system (MEMS) sensor architectures are specially designed for the dynamic suspension system, which can reduce the fluctuation caused by tire load and improve the strength of rib steel after the vehicle stops and crosses the water on the road

both sensors have full digital signal processing capability and adopt digital double limit psi5 interface. This type of interface provides a fail safe signal transmission device with programmable characteristics, which can use the sensor in the control system. The psi5 interface also reduces the structural complexity by reducing the physical method of external wiring, which currently only includes graphene and sensor cables

at present, two new types of sensors have been put into sample production. For details, please refer to the community technology frontier article "Bosch SMB acceleration sensor for automotive chassis control"
