Reporters obtained the following quote from the background information supplied by the inventors: “Being aware of hazardous driving conditions can aid in improving the likelihood of a safe driving experience. However, often drivers rely on navigational guidance systems that do not alert drivers of upcoming driving hazards. Although many vehicles include sensing devices to detect changing conditions, those devices may be best suited to evaluate current conditions rather than conditions associated with a road segment that a driver is approaching. Accordingly, it may be advantageous to detect upcoming potential dangers and provide adequate warnings to drivers.”
In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors’ summary information for this patent: “The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosure. The summary is not an extensive overview of the disclosure. It is neither intended to identify key or critical elements of the disclosure nor to delineate the scope of the disclosure. The following summary merely presents some concepts of the disclosure in a simplified form as a prelude to the description below.
“Aspects of the disclosure relate to methods, computer-readable media, systems, and apparatuses for determining a blind corner navigational score based on real-time or near real-time navigational analysis using sensor data, digital image data, and a map database. In some arrangements, the system may be a blind corner navigation system that includes at least one processor; and at least one memory storing computer-executable instructions that, when executed by the at least one processor, cause the blind corner navigation system to perform blind corner analysis.
“For example, in some arrangements, the system may receive predefined navigational data from a map database system, process the predefined navigational data to detect an upcoming blind corner, receive dynamic navigational data from a digital imaging device, process the dynamic navigational data to determine a blind corner navigational score, the blind corner navigational score indicating a likelihood that the upcoming blind corner is visible from a vantage point of a vehicle, determine whether the blind corner navigational score is above a first threshold, and responsive to a determination that the blind corner navigational score is above a first threshold, transmitting one or more of a warning signal or a vehicle control signal to the vehicle. In at least some arrangements, the digital imaging device may be mounted on the vehicle. The dynamic navigational data may include one or more digital images transmitted from the digital imaging device. In one instance, processing the dynamic navigational data to determine a blind corner navigational score may include performing image analysis on the one or more digital images. For example, the predefined navigational data may include information indicative of a location of a landmark, and performing image analysis may include comprises determining whether the landmark is visible within the one or more digital images.
“In at least some arrangements, transmitting the one or more of a warning signal or a vehicle control signal to the vehicle may include transmitting a first audio signal to the vehicle responsive to determining that the blind corner navigational score is above a second threshold and transmitting a first vehicle control signal to the vehicle responsive to determining that the blind corner navigational score is above a third threshold. The first vehicle control signal may be associated with a vehicle control event that is adjusted based on a response time of the vehicle. The first threshold may be dynamically modified based on weather conditions and/or a condition of a road on which the vehicle is currently located.
“Other features and advantages of the disclosure will be apparent from the additional description provided herein.”
The claims supplied by the inventors are:
