In one embodiment, a dynamic set of vehicle parameters of the ADV associated with a road location is determined based on IMU outputs of the ADV measured as the ADV travels through the road location. It is determined whether the set of dynamic vehicle parameters satisfies one of a first set of criteria and a second set of criteria. A speed limit associated with the road position is adjusted within a limited range from a minimum speed limit to a maximum speed limit in response to a number of times the dynamic vehicle parameter set satisfies a first predetermined amount of the first set of criteria or a number of times the dynamic vehicle parameter set satisfies a second predetermined amount of the second set of criteria. Operation of the ADV is controlled based at least in part on the adjusted speed limit as the ADV subsequently travels through the roadway location.
在一个实施方式中,基于在ADV行进通过道路位置时测量的、ADV的IMU输出来确定ADV的与道路位置相关联的动态车辆参数集。确定该动态车辆参数集是否满足第一标准集和第二标准集中的一个。响应于动态车辆参数集满足第一标准集第一预定量的次数或满足第二标准集第二预定量的次数,在从最小速度限制到最大速度限制的有限范围内调节与道路位置相关联的速度限制。当ADV随后行进通过道路位置时,至少部分地基于所调整的速度限制来控制ADV的操作。
