Abstract

In one embodiment, systems and methods are disclosed for a planning-driven framework for an autonomous driving vehicle (ADV) driving decision system. Driving decisions are classified into at least seven categories, including: conservative decision, aggressive decision, conservative parameters, aggressive parameters, early decision, late decision, and non-decision problem. Using the outputs of an ADV decision planning module, an ADV driving decision problem is identified, categorized, and diagnosed. A local driving decision improvement can be determined and executed in a short time frame on theADV. For a long term solution, if needed, the driving decision problem can be uploaded to an analytics server. The driving decision problems from a large plurality of ADVs can be aggregated and analyzed for improving the ADV decisions system for all ADVs.

Description

technical field [0001] Embodiments of the invention generally relate to operating an autonomous vehicle. More specifically, embodiments of the invention relate to improving driving decisions made by autonomous vehicles. Background technique [0002] Vehicles operating in an autonomous mode (e.g., driverless) can relieve occupants (especially the driver) from some driving-related duties. When operating in autonomous mode, the vehicle can navigate to various locations using onboard sensors, allowing the vehicle to travel with minimal human interaction or in some situations without any passengers. [0003] Motion planning and control are key operations in autonomous driving. The decision-making system of an autonomous vehicle (ADV) guides the vehicle's movement based on reactions to surrounding obstacles, traffic lights ahead, and nearby traffic signs (objects). A decision command consists of an intent for an object and one or more associated parameters for that intent. For...
