System Description - Direct Adaptive Steering System: Notes

- Instead of the conventional mechanical steering system, the direct adaptive steering that conveys the steering wheel operating to the tires by converting into an electrical signal was adopted.
- By converting the steering wheel operation into an electrical signal, the steering wheel operation is conveyed to the tires without delay.
- Even on a rough road surface, the direction of tires is controlled by the steering angle actuator control to prevent the unpleasant vibration from being conveyed to the steering wheel due to the rough road surface (the necessary information for driving, such as slipperiness of the road, is conveyed to the steering wheel).
- When the system is stopped or abnormal, the portions from the steering wheel to the steering gear assembly are connected mechanically while the steering clutch is engaged, and the steering wheel becomes operative.
- The steering angle actuator (steering gear assembly) and the steering force actuator (steering column) are controlled by 3 control modules. The 3 control modules share the computed result of each data and monitor each other.
- This system is linked with active lane control and applies a slight correction to the steering angle and the steering reaction force to improve the vehicle stability when the vehicle direction is shifted by a cross wind or other forces. For details, Refer to System Description

- Infiniti drive mode selector which can change the steering characteristic corresponding to the preference of the driver was adopted. For details, Refer to System Description

- This enables trouble diagnosis with CONSULT.
