Abstract

A forward collision warning alert system for an autonomous driving vehicle safety operator is provided. In one embodiment, a first trajectory is generated for a driving environment using control values allowed for a driving-by-wire system. If the trajectory includes a collision with an object, the ADV estimates the time of the collision and the relative speed between the ADV and the object at the time of the collision. A second trajectory is then generated for the driving environment using control values allowed for a human driver. The time of the collision and the relative speed between the ADV and the object at the time collision on the second trajectory are also estimated. The ADV then compares the two collision times and the two relative speeds, and based on the comparison, generates an alert message for the human driver to take over the control of the ADV.

Description

technical field [0001] Embodiments of the present disclosure generally relate to operating autonomous vehicles. More particularly, embodiments of the present disclosure relate to generating alerts for human safety operators when manual driving reduces the likelihood of a collision. Background technique [0002] A vehicle operating in an autonomous mode (eg, driverless) can relieve the occupants, especially the driver, of some driving-related responsibilities. When operating in autonomous mode, the vehicle can navigate to various locations using on-board sensors, allowing the vehicle to travel with minimal human interaction or in some situations without any passengers. [0003] Autonomous vehicles (ADVs) can be operated by a drive-by-wire system or by a human driver. Typically, by design, drive-by-wire systems do not have the same control capabilities as a human driver. For example, a deceleration designed for a drive-by-wire system is limited to 0.2G, while a human driver...
