摘要： An illustrative example system includes at least one alertness detector that is configured to detect an alertness condition of a driver of a vehicle and an alertness condition of a passenger in the vehicle. A controller is configured to determine a sleep risk factor based on the alertness condition of the passenger. The controller is also configured to determine a likelihood that the driver is sleepy based on the alertness condition of the driver and the sleep risk factor. The controller is configured to control a feature of the vehicle to assist the driver when the determined likelihood satisfies a predetermined criterion.

摘要： This document describes techniques and systems to indirectly verify speed limits based on contextual information for autonomous and semi-autonomous driving systems. In addition to camera systems, the described techniques and systems use other sensors and secondary factors to improve the accuracy and confidence in detecting posted speed limits. For example, a camera system captures an image or other data directly indicative of a speed limit. Contextual information for the road or vehicles nearby is also obtained and used to determine at least one indirect indication of the speed limit. A composite speed limit is identified by applying a respective weight to the direct and indirect indications of the speed limit. The described systems and techniques thereby enable controlling the vehicle based on the composite speed limit. In this way, the described systems and techniques can verify a speed limit to make autonomous and semi-autonomous driving systems safer.

摘要： A system includes a controller circuit configured to monitor, while a host vehicle is operated in a manual driving mode, a speed change response of an operator of the host vehicle based on a movement of a first vehicle traveling on a roadway, identify at least one speed parameter based on the speed change response, and apply, when the host vehicle is controlled in an autonomous driving mode, the at least one speed parameter based on the movement of a second vehicle traveling on the roadway.
