TRW has launched its first ESC system with an integrated inertial measurement unit (IMU) on the Lancia Delta, to perform previously discrete sensor data acquisition directly within the ESC electronics module.

Traditionally ESC systems have been introduced with a stand-alone IMU.  TRW will now produce an ESC with integrated IMU as a viable way to reduce the number of modules in the vehicle while retaining the performance of the ESC.  By integrating the IMU directly into the ESC, TRW is able to reduce the ESC system cost, weight and wiring harness complexity. The integrated design also provides a convenient scaleable solution for vehicle manufacturers wishing to offer both ABS and ESC braking systems within a model range.

With ESC mandates in place in North America and Europe, TRW's strategy also includes further sensor integration at the silicon level to offer additional cost, performance and reliability advantages.

– "We are pleased to launch this advanced, integrated ESC system with the Fiat Group" – said Josef Pickenhahn, vice president, braking engineering for TRW – "As an electronics safety systems specialist, TRW has the depth of knowledge to offer our customers a full array of integration options and is relentlessly pursuing higher levels of safety and performance." – said Pickenhahn.
