Data mining to identify locations of potentially hazardous conditions for vehicle operation and use thereof

Disclosed is a feature for a vehicle that enables taking precautionary actions in response to conditions on the road network around or ahead of the vehicle. A database that represents the road network is used to determine locations where a potentially hazardous condition exists. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken relating to the hazardous condition. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to determine when the vehicle is at a location that corresponds to the location of a precautionary action. When the vehicle is at such a location, a precautionary action is taken by a vehicle system as the vehicle is approaching the location where the potentially hazardous condition exists.

Using v2x-based in-network message generation, aggregation, distribution and processing protocols to enable road hazard condition warning applications

A method for providing messages indicating potential hazardous road conditions using a wireless communications network. Vehicles using the network include sensors that are able to detect various potentially hazardous road conditions, such as rain, fog, icy road conditions, traffic congestion, etc. A plurality of vehicles that detect a specific road condition provide a confidence value that the condition exists. The confidence value is then aggregated by the vehicles with the confidence value of the detected condition from the other vehicles to provide an aggregated result that identifies the probability that the detected road condition is occurring. The aggregated result is then transmitted to other vehicles approaching the road condition, possibly in a multi-hop manner. Alternately, the confidence value from all of the vehicles that detect the condition can be transmitted to approaching vehicles who will provide the aggregated result identifying the potential that the condition exists.

Smart occupant alarm system

An occupancy alarm system can be integrated into a motor vehicle or can be portable. The occupancy alarm system may be programmed to communicate with a program within a logic unit of the on-board computer within the vehicle or a cellular telephone or other wireless logic device so that if the driver's door is open and the engine is turned off but there still is an occupant in the motor vehicle, an alarm is immediately triggered. The GPS coordinates of the motor vehicle or the cellular telephone or other wireless device may be communicated to a remote location service or a local emergency center as part of the alarm. The occupancy sensor may be mounted on the occupant or on the restraint system, and may interact with an ambient temperature sensor and an alarm, both of which may be integrated into a motor vehicle, to indicate that a dangerous condition exists for an occupant within the motor vehicle. The occupancy sensor, the ambient temperature monitor, and the alarm may further be integrated together for a portable alarm system or may be mounted or otherwise integrated onto a portable restraint system. The occupancy alarm system may provide an interface and an override such that when the occupant remains in a potentially hazardous environment, that state is communicated via the interface and, if monitored by a responsible adult, the alarm can be overridden.

Method for observation of a person in an industrial environment

Manufacturing processes profit greatly from a close collaboration between human and machine. Whereas a human behaves flexibly and adaptively but is inclined to make mistakes during repetitive work operations, machines operate quickly and exactly but are static and not very flexible. In order to enable an improved hazard protection in the context of a safe human-machine interaction, a spatial- and time-dependent variable degree of hazard is allocated to monitored spatial areas as a function of the current position and the current movement state of a machine or a machine element, as well as of the observed person. For this purpose, a multicamera system is used to acquire image data of the person in order to obtain the most detailed information possible about the position and alignment of a person, in particular also with reference to the body parts thereof, in an industrial environment. These image data are then examined with regard to the imaging of a person so that whenever a person has been detected in the image data, an articulated virtual 3D model of the human body is matched to this person hypothesis. Subsequently, this virtual body model is continuously matched to the movement behavior of the person detected in the image data. A hazard potential is determined using knowledge of the position and the movement behavior of the virtual body model in space. The hazard potential thus determined is subjected to a threshold value comparison in order to act upon the movement control of the machine or the machine part in the event of this threshold value being exceeded.
