    • Disclosed is a method to determine a vehicle's lateral velocity during abnormal driving situations of a vehicle during controlled side-impact or rollover crash tests that involve the pulling of a vehicle sideways into an object. A high-resolution, low-range, lateral accelerometer is integrated to determine the lateral velocity. Furthermore, is a method to initiate the integration of the acceleration signal and a method to stop and reset the integration. The method recognizes special conditions associated with abnormal driving situations like controlled crash tests, and therefore will not be active during normal operating conditions. The method also includes a means to handle offset tolerances associated with accelerometers by finding the sensor's zero-g point while the vehicle is at rest.
    • 公开了一种在涉及将车辆侧向拉入物体的受控侧撞或翻车碰撞试验期间确定车辆的异常驾驶状态期间的车辆横向速度的方法。 集成了高分辨率,低范围的横向加速度计来确定横向速度。 此外,是启动加速度信号的集成的方法以及停止和重置集成的方法。 该方法识别与异常驾驶情况(如受控碰撞测试)相关的特殊情况,因此在正常操作条件下不会起作用。 该方法还包括通过在车辆静止时找到传感器的零点而处理与加速度计相关联的偏移公差的装置。
