FIELD: control systems.
SUBSTANCE: invention relates to vehicle control systems. Driver anomaly detection system includes a computer in a vehicle. Computer comprises a processor and a storage device, the computer being configured to collect vehicle trajectory data, determine a current variance of the trajectory data, compute a speed-dependent weighting function to obtain a speed-dependent weigh, determine an anomaly index and instruct a controller in the vehicle to take an action based on the anomaly index. Determination of the current variance of the trajectory data is made using a prior variance determination of the trajectory data. Determination of driver anomaly is based at least in part on application of the speed dependent weight to the determined current variance.
EFFECT: higher safety of vehicle driving is achieved.
