When an own vehicle is highly likely to collide with an obstacle, a notification of prompting a driver to carry out a collision avoidance operation is appropriately given. When an output request for collision avoidance support information exists, a notification ECU notifies of the collision avoidance support information irrespective of absence/presence of an output request for vehicle-infrastructure cooperation support information. When the output request for the collision avoidance support information does not exist and the output request for the vehicle-infrastructure cooperation support information exists, the notification ECU notifies of the vehicle-infrastructure cooperation support information. Thus, when the conditions for the notification of the vehicle-infrastructure cooperation support information and the collision avoidance support information are simultaneously satisfied, the vehicle-infrastructure cooperation support information is inhibited from being notified and the collision avoidance support information is notified.

Support point management systems, methods, and programs acquire a support point registered as a subject of deceleration support and exclude the support point as the subject of deceleration support in a case a vehicle travels on a new road after having traveled through the support point without deceleration at the support point.

Systems, methods, and apparatuses are disclosed for determining lane information of a roadway segment from vehicle probe data. Probe data is received from radar sensors of vehicles at a road segment, where the probe data includes an identification of static objects and dynamic objects in proximity to the respective vehicles at the road segment, and geographic locations of the static objects and the dynamic objects. A reference point, such as a road boundary, at the road segment is determined from the identified static objects. Lateral distances between the identified dynamic objects and the reference point are calculated. A number of lanes at the road segment are ascertained from a distribution of the calculated distances of the identified dynamic objects from the reference point.

A collision avoidance system of a vehicle includes a sensor configured to be disposed at a vehicle for sensing exterior and forwardly of the vehicle. A processor is operable to process sensor data captured by the sensor to determine the presence of a pedestrian ahead of the vehicle and at or moving towards a path of travel of the vehicle. The processor determines a time to collision based on a determined distance to the pedestrian and determined speed of the pedestrian and speed of the vehicle. The collision avoidance system is operable to generate an alert to the driver of the vehicle at a threshold time before the determined collision with the pedestrian. Responsive to a parameter, the collision avoidance system adjusts the threshold time to generate the alert at an earlier time.

A taxi trip meter system includes a taximeter and a location sensor connected to a computer loaded with street information and driver evaluation software. In a first embodiment, the estimated shortest route and distance between the starting and ending points of a trip are determined. If the estimated shortest trip distance is exceeded by an actual trip distance by a permissible margin, a distance violation is indicated. An actual average speed is calculated based on an actual trip duration and the actually traveled distance. If an estimated average speed limit for the actual route is exceeded by the actual average speed, a speed violation is indicated. In a second embodiment, an estimated taxi fare is calculated based on the estimated shortest route. If the estimated taxi fare is exceeded by an actual taxi fare calculated by the taximeter by a permissible margin, a fare violation is indicated.

Disclosed herein are methods of providing location-based information with respect to a topological map. A method may include (a) receiving a query for location-related information, (b) optionally generating data representing the topological map, (c) accessing the location-related information in a map-to-scale, (d) optionally determining an association between one or more points (or links) in the map-to-scale and one or more corresponding points (or links) in a topological map, (e) identifying one or more points (or links) in the map-to-scale that relate to the location-related information and that correspond to one or more points (or links) in the topological map, (f) optionally determining a relative position of the location-related information with respect to the identified one or more map-to-scale points (or links), and (g) displaying the location-related information with respect to the corresponding one or more points (or links) in the topological map.

A vehicle system includes a high voltage battery and at least one control module configured to monitor the high voltage battery and command a visual warning in response to a disconnect event of the high voltage battery. The visual warning may be produced by a hazard light.

A measuring device for measuring a radar signal is provided. The radar signal is generated from a digital reference signal. The measuring device comprises a memory configured to store a digitized radar signal derived from the radar signal and the digital reference signal. The measuring device further comprises a radar compression filter configured to filter the digitized radar signal, resulting in a correlation of the digitized radar signal with the digital reference signal. The measuring device further comprises a frequency shifter configured to successively perform a frequency shift of either the digital reference signal or the radar signal with at least two simulated Doppler shift frequencies.

A simulator is provided for dynamically testing and evaluating an electromagnetic radiation in real-time. The performance of radiation from a system-under-test is evaluated as it interacts with a moving target in an ever-changing simulated environment. The simulator includes a computer for synchronized control of a PNT database and of an environmental database. In detail, the PNT database contains Position, Navigation and Timing (PNT) information of the target, and the environmental database contains information pertaining to meteorological conditions and topographical characteristics in the simulated environment. In combination, the computer evaluates a synchronized interaction of the electromagnetic radiation with the PNT information from the PNT database, under conditions set by the environmental database. A response record for evaluating a performance of the system-under-test is thereby created.
