Abstract

According to various embodiments, described herein are methods and systems for collecting data for training a load inference regression model for use in an ADV. According to one exemplary method, an ADV is manually driven on a segment of a road for a number of periods of time. During each period of time, a set of features of the ADV are recorded, including one or more features at a first time prior to a gear shift from a first gear position to a second gear position, and one or more features at a second time after the gear shift. For each of the number of periods of time, a weight of the ADV is also recorded using a weight sensor. The recorded features and the total weight of the ADV for each of the periods of time are then used to train a neural network regression model for inferring a load of the ADV in real time.

Description

technical field [0001] Embodiments of the present disclosure generally relate to operating an autonomous vehicle. More specifically, embodiments of the present disclosure relate to load extrapolation systems for autonomous vehicles. Background technique [0002] A vehicle operating in an autonomous mode (e.g., driverless) frees the occupants, especially the driver, from some driving-related duties. When operating in autonomous driving mode, the vehicle can navigate to various locations using on-board sensors, allowing the vehicle to drive with minimal human interaction or in some situations without any passengers. [0003] Autonomous vehicles (ADVs) rely on various actuator commands (eg, accelerator / brake) in real-time driving to control the ADV. Sometimes these actuator commands need to be dynamically adjusted based on the loads in ADV. Some other times, the ADV needs to know when the load on the ADV has reached the ADV's maximum capacity. However, weight sensors may no...
