The embodiment of the invention provides a safety belt adjusting method, system and device, and relates to the technical field of automobiles, the method comprises the following steps: obtaining the vehicle speed, the vehicle acceleration, the forward inclination angle of a passenger on a seat and the relative height measured by inertial measurement equipment, and the relative height is the height from the inertial measurement equipment to the seat after the passenger fastens a safety belt; and obtaining the weight of the user measured by the seat pressure sensor. And judging whether the automobile collides according to the automobile speed and the automobile acceleration. If yes, the inertial measurement equipment is controlled to obtain the forward inclination speed of the user, and the first duration after the collision occurs is recorded. And determining first tension of the safety belt according to the vehicle speed, the user weight, the forward inclination angle, the first duration and the relative height during collision. And determining a buffer tension range of the safety belt according to the weight of the user and the forward leaning speed, and controlling the first tension to be adjusted into second tension in real time. A user can be better protected by adjusting the tensile force of the safety belt.
本发明实施例提供了一种涉及汽车技术领域的安全带调节方法系统及装置,该方法包括:获取惯性测量设备测得的车速、车辆加速度、乘客在座椅上的前倾角度以及相对高度,相对高度为乘客系上安全带后惯性测量设备距离座椅的高度。获取座椅压力传感器测得的用户体重。根据车速以及车辆加速度判断汽车是否发生碰撞。若是,控制惯性测量设备获取用户的前倾速度,并记录发生碰撞后的第一时长。根据发生碰撞时的车速、用户体重、前倾角度、第一时长以及相对高度确定安全带的第一拉力。根据用户体重以及前倾速度确定安全带的缓冲拉力范围,并实时控制第一拉力调整为第二拉力。本发明可以通过调节安全带的拉力大小,更好地保护用户。
