The transformation of the intelligent driving system E/E also gave birth to the evolution of the intelligent chassis E/E. In the electromechanical hybrid period, the E/E architecture of the chassis system is a superposition of simple subsystems ECU. Although there is cooperation between subsystems, these cooperations are only reflected in the level of information sharing. Each subsystem is still “independent”, and the function control Constrained by each other, the response was slow, and the effect of “1+1>2” was not reflected. The performance of the vehicle dynamic control system (Vehicle Dynamic Control, VDC) is subject to the constraints of the traditional E/E architecture. VDC relies on the status input of the steering system and the braking system to judge whether the vehicle has a tendency to understeer or oversteer, and controls the yaw rate by correcting the wheel end braking force to bring the vehicle back to a stable state, although the steering system It has a direct impact on vehicle stability, but VDC does not directly intervene in the steering wheel angle control of the steering system. Therefore, in this process, the performance of the steering system will have a real-time impact on the speed of stability adjustment, but its impact can only make the steering system The dynamic system is in a “remedial adjustment” cycle. In other words, the steering system cannot play an “active assist” role for the stability control.
