The invention discloses a vehicle turning active kingpin caster angle control system and a control method. A vehicle state acquisition module acquires a vehicle steering gear rack position, a steering gear rack speed and a lateral acceleration signal, and sends the acquired signals to an ECU (Electronic Control Unit); the ECU comprehensively judges a vehicle driving intention according to a vehicle steering gear rack position, a steering gear rack speed and a lateral acceleration signal sent by the vehicle state acquisition module, identifies that the vehicle enters a corresponding curve control mode according to the driving intention, and sends a control instruction to the active kingpin caster angle adjustment actuator in the corresponding curve control mode; the active kingpin caster angle adjusting actuator executes corresponding operation according to the instruction sent by the ECU, and the expected running state of the vehicle is obtained by setting the front axle kingpin caster angle. The kingpin caster angle of the vehicle is reasonably adjusted, so that the vehicle enters the curve and runs out of the curve more flexibly, and the safety and comfort of the vehicle are improved.

    本发明公开了一种车辆转弯主动主销后倾角控制系统及控制方法,车辆状态采集模块采集车辆转向器齿条位置、转向器齿条速度以及侧向加速度信号,并将采集信号发送至ECU;ECU根据车辆状态采集模块发送的车辆转向器齿条位置、转向器齿条速度以及侧向加速度信号,综合判断车辆驾驶意图,并根据驾驶意图识别车辆进入对应弯道控制模式,在对应的弯道控制模式下向主动主销后倾角调整执行器发送控制指令;主动主销后倾角调整执行器根据ECU发送的指令执行相应的操作,通过设定前轴主销后倾角,获得车辆预期的运行状态。本发明通过合理调整车辆主销后倾角,使车辆进入弯道、驶出弯道更加敏捷机动,从而提高车辆的安全性及舒适性。
