The invention discloses an automobile steer-by-wire system and a control method, and relates to the technical field of automobile steering systems.The automobile steer-by-wire system comprises a whole automobile controller, a steering controller, a steer-by-wire system and a traditional steering system.The whole automobile controller collects automobile information and user willingness and controls the steer-by-wire system and the traditional steering system. The steering controller is controlled to achieve wake-up work of the steer-by-wire mechanism, execution of steer-by-wire actions is finally achieved through verification of the steps of steer-by-wire mechanism steering risk assessment, steering safety protection and the like, and in the two actions of steer-by-wire mechanism steering risk assessment and steering safety protection, steer-by-wire verification information is fed back to the whole vehicle controller. All-step risk monitoring is achieved, and the industrial technical problems that in the prior art, an intelligent automobile cannot quickly respond in complex working conditions, optimal control conditioning distribution cannot be achieved in real time, and the safety and reliability of steer-by-wire cannot be guaranteed are solved.

    本发明公开了一种汽车线控转向系统及控制方法,涉及汽车转向系统技术领域,所述汽车线控转向系统包括:整车控制器、转向控制器、线控转向系统和传统转向系统,整车控制器通过采集车辆信息及用户意愿,控制转向控制器实现线控转向机构唤醒工作,通过线控转向机构转向风险评估、转向安全保护等步骤的校验,最终实现线控转向动作的执行,在线控转向机构转向风险评估、转向安全保护的两个动作中,将线控校验的信息反馈至整车控制器,实现全步骤的风险监控,解决现有技术中智能汽车无法在复杂工况中快速响应、无法实时实现最优控制调理分配、无法保证线控转向安全可靠性的行业技术难题。
