Gain/phase control front steering, rear axle steering and compliance steer control for trucks and buses

摘要

The driving performance of a vehicle with front wheel steering system is enhanced by controlling the gain and/or phase-lag characteristics. A vehicle with rear axle steering system has an even or higher effect than that. The compliance steer control effect in mechanical system is the key technology for enhancing the on-center stability. Driver's error compensating system by steering and/or brake system control will be in the future, and the manual and autonomous control hybrid driving system will follow it.
