DRIVING ASSISTANCE APPARATUS, VEHICLE, DRIVING CONTROL METHOD, AND PROGRAM
The driving assistance apparatus comprises a camera device configured to obtain a camera image by taking a picture of a predetermined area ahead of a host vehicle; and a control unit configured to drive the host vehicle so as to cause an acceleration of the host vehicle to become equal to a follow-up acceleration to make an inter vehicle distance to a preceding vehicle coincide with a target inter vehicle distance. When the preceding vehicle is a large-size vehicle, the control unit obtains the target inter vehicle distance for causing a traffic-signal-equipment-distance indicative of a distance to a traffic signal equipment of when the traffic signal equipment is detected above the preceding vehicle in the camera image to be longer than a stop-required-distance for which the host vehicle travels until the host vehicle stops under the assumption that the host vehicle decelerates at a predetermined deceleration.
DETERMINING A CONTENT OF A MESSAGE USED TO COORDINATE INTERACTIONS AMONG VEHICLES
A system for determining a content of a message used to coordinate interactions among vehicles can include a processing device and a memory. The memory can store a discretization module and a communications module. The discretization module can include instructions that when executed by the processing device cause the processing device to: (1) analyze a critical maneuver trajectory of an ego vehicle and a current trajectory of another vehicle to determine an existence of a critical maneuver situation and (2) produce a discretized representation of a portion of the critical maneuver trajectory of the ego vehicle. A form of the discretized representation can be based on the existence of the critical maneuver situation. The communications module can include instructions that when executed by the processing device cause the processing device to communicate the discretized representation as the content of the message used to coordinate interactions among vehicles.
Inward/outward vehicle monitoring for remote reporting and in-cab warning enhancements
Systems and methods are provided for intelligent driving monitoring systems, advanced driver assistance systems and autonomous driving systems, and providing alerts to the driver of a vehicle, based on anomalies detected between driver behavior and environment captured by the outward facing camera. Various aspects of the driver, which may include his direction of sight, point of focus, posture, gaze, is determined by image processing of the upper visible body of the driver, by a driver facing camera in the vehicle. Other aspects of environment around the vehicle captured by the multitude of cameras in the vehicle are used to correlate driver behavior and actions with what is happening outside to detect and warn on anomalies, prevent accidents, provide feedback to the driver, and in general provide a safer driver experience.
