The present invention extends to methods, systems, and computer program products for consolidating information from different signals into an event. Aspects of the invention used a multiphase approach to consolidating information from different signals into (e.g., deduplicating) an event. Detected events are held in the event holding cache for some amount of time after detection in accordance event holding criteria. As events are detected, an information consolidator compares currently detected events to previously cached events. Events determined to be the same event are grouped into an event group. When holding criteria expire for an event in the event group, the event group is published to one or more entities. As such, each new detection of the event does not trigger a corresponding new notification. Different portions of content from the same signal can also be monitored to reduce duplicate detections based on different content types in the same signal.

Predetermined calibration table-based vehicle throttle/brake assist system for L2 autonomous driving
In one embodiment, in response to a first control command originated from a driver of an ADV, an expected acceleration of the ADV in response to the first control command is determined in view of a current speed of the ADV under the standard driving environment (e.g., dry road, flat road surface, normal tire pressure, zero load). One of the command calibration tables is selected based on a current driving environment of the ADV at the point in time. A lookup operation is performed in the selected command calibration table to obtain a second control command based on the current speed and expected acceleration of the ADV. The second control command is then issued to the ADV to control the ADV. As a result, the ADV would have reached the same acceleration under the current driving environment as if the ADV was driving in the standard driving environment.
