P/S System Description

Power steering system employs an electronic power steering (EPS) system that is of a column assist type. EPS system consists of P/S control module incorporated in P/S motor, and torque sensor. All of them are included in steering column assembly.

The controllability of assisting steering force is optimized in all vehicle speed ranges.

The P/S control module controls vehicle dynamics synthetic control with BCM and ESP^® control module through CAN communication network. If the BCM detects a tendency of vehicle oversteering, the P/S control module performs countersteering assist torque control. This cooperative vehicle dynamic synthetic control takes place when vehicle speed is above 30 km/h (19 mile/h) with steering angle of 20° or more. For location of EPS system components, refer to Power Steering Control System Component Location.
