Abstract

The invention provides an automobile active steering control system and method based on vehicle-road collaboration. The position range of automobile swerving, the theory vehicle speed and the theory engine rotating speed are calculated through an active steering control unit according to the surrounding information of automobiles collected through a sensor and road surface information transmittedthrough a roadbed signal projector beside the road; the theory vehicle speed and the theory engine rotating speed are transmitted to a restrictor regulator and an engine rotating speed controller to adjust the vehicle speed and the engine rotating speed; and when the automobiles swerve, the system can detect the rotating angle of a steering wheel and send the inspected value to the active steeringcontrol unit, a steering additional angle is obtained after process and calculation, and the steering additional angle is sent to a steering wheel rotating angle controller, so that real-time activesteering control is realized. According to the automobile active steering control system and method based on the vehicle-road collaboration, based on the vehicle-road collaboration thought, the control process is combined with concrete road information, a model prediction method is adopted, and safety, stability and reliability of automobile steering are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of automobile engineering, and in particular relates to an automobile active steering control system and method based on vehicle-road coordination.
