Abstract: This article provides insight into the trends in automotive electrification as we move toward partial and full autonomous driving and, in particular, the changes required to make electrical power steering (EPS) and electrical braking systems meet the necessary safety standards to ensure the safe and reliable control of driverless vehicles. Analog Devices, Inc. (ADI) is a provider of magnetoresistive (MR) position sensor products and shunt-based current sense amplifier products enabling high performance commutation and safe operation of brushless motors used in EPS and electrical braking systems.
Key words: motor position sensor; automotive electrification; EPS; electrical power steering; safe; ADI; MR; magnetoresistive
