Development of Differential Gear Type Active-Front-Steering System

摘要

JTEKT has developed a new active-front-steering system that greatly contributes to vehicle safety. This system includes a unit comprising two motors and a differential gear mechanism capable of controlling steering angle and compensating for reactive torque, making steering compensation without driver interference possible. By creating a unit with these functions, we have provided a system with a lightweight, low-cost design that does not require tuning work for each vehicle. Furthermore, it has been verified by on-vehicle evaluation that this system improves vehicle safety.
