The invention discloses an energy-saving automobile steer-by-wire mechanism and a control method. The steer-by-wire mechanism comprises a steering wheel, a steering wheel sensor, a front steering shaft, a front gear rack, a first air chamber, a second air chamber, a first piston rod, a second piston rod, a first air pressure sensor, a second air pressure sensor, a rear gear rack, a rear transmission shaft, a road feel feedback motor, a feedback gear, an electromagnetic clutch, a steer-by-wire executing mechanism, a magneto-rheological damper and a steer-by-by-wire ECU. The steer-by-wire ECU controls the magneto-rheological damper, the road feel feedback motor, the electromagnetic clutch and the steer-by-wire executing mechanism to work according to induction signals of the steering wheel sensor, the first air pressure sensor and the second air pressure sensor and vehicle speed and yaw velocity signals of the vehicle. The energy utilization rate of the electric automobile is further increased, and energy consumption is reduced.

    本发明公开了一种节能汽车线控转向机构及控制方法,线控转向机构包括转向盘、转向盘传感器、前转向轴、前齿轮齿条、第一至第二气室、第一至第二活塞杆、第一至第二气压传感器、后齿轮齿条、后传动轴、路感反馈电机、反馈齿轮、电磁离合器、线控转向执行机构、磁流变阻尼器、线控转向ECU。线控转向ECU根据转向盘传感器、第一气压传感器、第二气压传感器的感应信号以及汽车的车速、横摆角速度信号控制磁流变阻尼器、路感反馈电机、电磁离合器、线控转向执行机构工作。本发明进一步提高了电动汽车的能量利用率,减少能源消耗。
