Detection of driver behaviors using in-vehicle systems and methods
A system includes a motion sensor system configured for deployment in a cab of a vehicle and to generate substantially in real-time a digital mapping of driver movement during operation of the vehicle. A computer is configured for deployment in the cab and coupled to the motion sensor system. A driver behavior detector is coupled to the computer and configured to detect a driver distraction event using the driver movement mapping. A communication device at the vehicle is configured to communicate an alert message to one or both of a user interface device in the cab and a remote system in response to the detected driver distraction event.
PREDICTION OF DRIVER INTENT AT INTERSECTION
A system and method for predicting whether a driver of a host vehicle or a remote vehicle intends to make a left or right turn or travel straight through an intersection before the host vehicle or remote vehicle reaches the intersection that relies on a probability model that employs a dynamic Bayesian network. The method includes obtaining a plurality of environmental cues that identify external parameters at or around the intersection, where the environmental cues include position and velocity of the remote vehicle, and obtaining a plurality of host vehicle cues that define operation of the host vehicle. The method then predicts the turning intent of the host vehicle and/or remote vehicle at the intersection using the model based on both the external cues and the vehicle cues using the model. The model can use learned information about previous driver turns at the intersection.
VEHICLE ACCIDENT AVOIDANCE SYSTEM
Method and system are provided for vehicle accident avoidance carried out with respect to a host vehicle by modeling behavior. The method includes: monitoring a surrounding environment of the host vehicle and detecting other vehicles in a vicinity of the host vehicle by at least one visual sensor. The method further includes: estimating a speed and direction of each of the detected vehicles; calculating one or more projected paths of each of the detected vehicles based on their current estimated speed and direction, the current monitored surrounding environment, and other vehicle projected paths; estimating a probability of intersection of each projected path with the host vehicle; and providing an alert or action to the host vehicle if there is a high probability of intersection.
Vehicle driving support control device
In a driving support system of a vehicle, there is provided a structure that, even during operating a control based on a machine input, a driver's sense of incongruity can be reduced as much as possible and/or the steering of the driver be can reflected. The vehicle is equipped with a steering assist mechanism and a braking-driving force distribution mechanism of right and left wheels. In operations of the inventive device, a steering assist torque, applied by the steering assist mechanism, is controlled to a target value determined with reference to a target steering torque to achieve the target route, determined without depending on steering of a driver, and a driver's steering torque; and a braking-driving force difference between the right and left wheels is controlled to a target value based on a steering angle of the driver.

In one embodiment, a method comprises, during operation of a vehicle by a driver, collecting vehicle environment status information inside a cabin of the vehicle, the vehicle environment status information related to environmental factors that may impact a cognitive load of the driver and including at least one of information regarding one or more passengers of the vehicle; and information from one or more dashboard controls of the vehicle; and based on the vehicle environment status information and an estimated physiological state of the driver, adjusting one or more environmental controls of the vehicle.
System for alarming a driver using a driver state estimation device
In a first arousal level estimation device according to this invention, an initial residual setup unit sets a residual to be a reference of a driver, i.e., a residual with a smallest value during an initialization period as an initial residual among residuals calculated by a residual calculation unit during the initialization period from timing of starting an operation of a vehicle or timing of a change in a traveling scene including a condition of traveling road of the vehicle as a starting point till a predetermined period of time elapses. An arousal level estimation unit estimates a driver's arousal level based on a result of comparison between the initial residual set by the residual setup unit and the residual calculated by the residual calculation unit after the initialization period has elapsed. In this way, an estimation accuracy relating to a driver's state including a driver's arousal level is improved.
