Imu feedback based hd map speed limit adjustment system

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

• determining a set of dynamic vehicle parameters of an autonomous driving vehicle (ADV) associated with a road location based on outputs of an inertial measurement unit (IMU) of the ADV measured when the ADV is traveling through the road location;
• determining whether the set of dynamic vehicle parameters satisfy one of a first set of criteria and a second set of criteria;
• in response to the dynamic vehicle parameters satisfying the first set of criteria for a first predetermined quantity of times or satisfying the second set of criteria for a second predetermined quantity of times, adjusting the speed limit associated with the road location within a limited range spanning from a minimum speed limit to a maximum speed limit;
• and
• controlling operations of the ADV when the ADV subsequently travels through the road location based at least in part on the adjusted speed limit.
