System Description: Outline
- Digital motion control is the active suspension control technologies based on "Skyhook theory". And the system is controlled by chassis control module mainly.
- Chassis control module estimates the body motion (such as bounce, roll and pitch) by each wheel speed and the driving condition according to received signal from each unit via CAN communication.
- Chassis control module controls shock absorber actuator in the most suitable damping force every 1/100 second depending on the estimated body motion.
- High speed proportion solenoid valve is used for shock absorber actuator in the dynamic digital suspension. Thereby, the system is able to achieve "Skyhook Control" continuously.
- The characteristic of suspension control can be changed by "Infiniti InTuition" with each driver. For details, refer to SYSTEM DESCRIPTION .
