Study on the Safety of Automobile Electric Power Steering Gear

Electric power steering (EPS) as a new type automotive assistant steering device has been developing rapidly in recent years around the world. Due to the adoption of programmable electronics, the EPS has safety concerns besides flexibility. Based on the analysis of its particularities and the characteristics of electronic control device, hazardous factors were discussed, and countermeasures suggested. The study shows that current standards are not suitable to EPS safety requirements, and the concept of safety evaluation of EPS was also put forward. The results could be referred in the development and evaluation of EPS.
