Distributed steering by wire control using time-triggered protocol communication network

摘要

The present invention involves a distributed control system for controlling a steering movement of a vehicle. The system includes a driver interface assembly, a driver interface node having a first time-triggered protocol (TTP) processing system and a road wheel node having a second time-triggered protocol (TTP) processing system. The driver interface node having a first time-triggered protocol (TTP) processing system is coupled to the driver interface assembly, where the driver interface node receives steering wheel parameters from the driver interface assembly. The road wheel node having the second time triggered protocol (TTP) processing system is coupled to the driver interface node, where the road wheel node transmits sensor measurements from a vehicle to the driver interface node. The road wheel node generates an applied torque that adjusts a wheel of the vehicle.
