Recently, Huawei Technologies Co., Ltd. “traffic distress and road rage detection method” patent was granted.
The abstract shows that the patent provides a system for determining traffic distress for a driver of a vehicle, including multiple sensors: an in-vehicle image sensor, an in-vehicle audio sensor, a vehicle data sensor, and a global positioning system (referred to as GPS) data sensor; Also included is one or more processors for receiving inputs from the plurality of sensors and processing the received inputs to obtain driver thermal change estimates, driver expression estimates, driver posture estimates, onboard diagnostic system estimates, and GPS estimates.
The aforementioned processor is also used to store the estimates in memory, use the stored estimates to generate a deviation score for each estimate, and execute a machine learning algorithm to classify driver behavior as normal or abnormal based on the deviation score, Alerts are generated based on classifications that indicate abnormal driver behavior.
