The invention provides a vehicle sensing device for a safety belt retractor and a control method, and is applied to the technical field of vehicle safety device.An actuator is a metal pin-shaped component and can move from an initial position to an actuating position of a pushing and ejecting actuator in the axis direction of the actuator; when the vehicle encounters an emergency situation or detects that the acceleration of the vehicle reaches a threshold value, the vehicle sensing device responds to a trigger signal through the electromagnetic driving assembly and generates a magnetic field to drive the actuator to move towards the actuating position after being powered on, and the actuator pushes the actuator to rotate and lock the safety belt retractor to protect passengers. The vehicle sensing device is not limited by a horizontal installation state any more, the installation angle range of the vehicle sensing device and the retractor is enlarged, and the vehicle sensing device has low operation noise and vibration noise.

    本申请提供一种安全带卷收器用车感装置及控制方法,应用于车辆安全装置技术领域,其中,致动器为金属销状部件,且致动器可沿自身轴线方向上从初始位置至推顶执行器的致动位置间移动,在车辆遇到突发状况或检测到车辆加速度达到阈值时,该车感装置通过电磁驱动组件响应触发信号并通电后产生磁场驱动致动器向致动位置移动,致动器推顶执行器转动锁止安全带卷收器对乘员进行保护,该车感装置不再受限于水平安装状态,扩大了车感装置和卷收器的安装角度范围,且该车感装置具有较低的运行噪音和震动噪音。
