Sensor Cluster for sensing the Vehicle Dynamics

The sensor cluster makes available to all devices in the vehicle the vehicle’s current movement status (yaw rate, longitudinal and lateral acceleration, and optionally, pitch and roll rates) in the form of electronic signals. The verified signals are transmitted to the data bus via a standardized interface, which can also be adjusted on a customerspecific basis. In complex control algorithms, these signals are used to initiate vehicle stabilization when ESC control is activated. The signals are also needed for driver assistance systems.

Derivatives of the standard sensor cluster for the Continental ESC in passenger cars have the following applications:

  • Sensor cluster with customer-specific interface for applications in external systems
  • Redundant sensor cluster for high safety requirements regarding the control system (SIL3)
  • Sensor cluster for ESC applications in the truck market with freely programmable MCU
  • Sensor box to measure the tilt angle during motorcycle operation
  • Sensor cluster with several degrees of freedom for the industrial sector as a catalog part with a J1939 interface

SC2012 Sensor – highest integration of signal sensing

An innovation in inertial measurement technology is the measurement of the yaw rate and the acceleration in a single component (SC2012 Sensor). The integration in one housing includes the MEMS elements for measurement of the acceleration and the yaw rate, and the corresponding combi ASIC for signal processing.

Due to its compact design as an SMD component, and the capability of adapting the calibration flexibly to the relevant requirements, the SC2012 Sensor is used not only in sensor clusters, but also in other control devices. The introduction of this innovation enables manufacturers to considerably reduce the size of all electronic devices that measure yaw rates and acceleration.
