Abstract

The invention discloses a combination control system for integration electric power steering and active steering. The combination control system for integration electric power steering and active steering comprises an active steering control system, an electric power steering control system, an adjustment control system based on yaw velocity and an adjustment control system based on steering wheel moment, the active steering control system and the electric power steering control system are respectively connected with a vehicle speed sensor and a steering wheel angle sensor for calculating and processing the inputted vehicle speed and steering wheel angle and outputting the total front wheel angle control signal to the total system for steering the front wheel actively; the adjustment control system based on yaw velocity is used for adjusting the obtained yaw velocity value for having feedback to the active steering control system for amending the front wheel angle control signal; the adjustment control system based on steering wheel moment is used for adjusting the obtained steering wheel moment for having feedback to the electric power steering control system for amending the outputted front wheel angle control signal.

Description

technical field

[0001] The invention relates to the field of automobile control, in particular to a combined control system integrating electric power steering and active steering. Background technique

[0002] Active Steering System (AFS) is an inevitable development requirement for future automotive automatic driving, driving stability control and comfort control (variable transmission ratio control). At present, based on safety considerations, the AFS that uses the combination of manual manipulation and electric superposition to control steering has been put into practical use. In terms of power steering, Electric Power Assist (EPS) has developed rapidly and has become the first choice for small cars. With the gradual application of AFS and the transfer to middle and low-end cars, the combination of AFS and EPS will become a future demand. However, there is currently no control system that effectively uses the combination of AFS and EPS. Contents of the invention [...
