Understanding driver awareness through brake behavior analysis
First Claim
1. A system for analyzing a driver'"'"'s brake behavior, the system comprising:
- a memory that stores instructions for executing processes for analyzing the driver'"'"'s brake behavior; and
a processor configured to execute the instructions, wherein the processes comprise;
receiving data from one or more multi-modal sensors, the data including one or more characteristics of a road and one or more physiological signals of the driver;
determining whether each braking event of a plurality of braking events is a hard braking event;
analyzing the one or more physiological signals of the driver to determine whether each of the hard braking events is a reactive hard braking event or an intended hard braking event, wherein the analyzing comprises determining whether a change of each of the one or more physiological signals of the driver exceeds a threshold value during the hard braking event;
applying a Lasso regression analysis and a classification framework for each of the hard braking events to identify road features that indicate whether a respective hard braking event is a reactive hard braking event or an intended hard braking event; and
generating a signal notifying a vehicle of the features that indicate whether the respective hard braking event is a reactive hard braking event or an intended hard braking event.
