A system for classifying pulses from a sensor configured to detect one or more objects includes a processor and a memory in communication with the processor. The memory has a pulse classification module having instructions that, when executed by the processor, cause the processor to obtain a signal having a pulse and classify the pulse as one of: (1) a single object pulse indicating that the one or more objects represented by the pulse is a single object and (2) a plurality of objects pulse indicating that the one or more objects represented by the pulse are multiple objects. The classification of the pulse may utilize one or more of the following: a pulse width of the pulse, a rising slope of the pulse during a rising period, a falling slope of the pulse during a falling period, and a saturating width of the pulse.

System and method for classifying pulses generated by a sensor

A position recognizing device according to one embodiments of the present disclosure includes a ranging point acquiring section, a region determining section, and a ranging point excluding section. The ranging point acquiring section is configured to acquire ranging point information in which distances to ranging points are associated with each of electromagnetic wave applying directions. The region determining section is configured to determine whether an object region that represents a region encompassed by joining ranging points that are in close proximity to one another exists at a position closer than a specific ranging point representing a certain ranging point among the ranging points. The ranging point excluding section is configured to define the ranging point in front of which the object region exists as a false image point at which no object actually exists and exclude the false image point from the ranging point information.

Position recognizing device

In an apparatus for correcting a location of a vehicle, a satellite positioning unit mounted in the vehicle measures the location of the vehicle using navigation satellites. A locational trajectory generating unit generates a locational trajectory of the vehicle based on the location of the vehicle measured by the satellite positioning unit. A location correcting unit corrects the location of the vehicle based on the locational trajectory and map information stored in a map information storage. The location correcting unit, for each of the vehicle locations included in the locational trajectory, determines in which one of the lanes of the road the vehicle was traveling as the vehicle location was measured, and geometrically compares at least one traveled lane of the road acquired from the determination and the locational trajectory, and based on the comparison, calculates a locational correction amount of the location of the vehicle.

Apparatus for correcting vehicle location

A vehicle identification apparatus mounted in a vehicle provided with a detection unit configured to detect a speed of a first other vehicle and a communication unit configured to receive information indicative of a speed of a second other vehicle from the second other vehicle. In the apparatus, a calculation unit calculates an indicator value indicative of a likelihood that the first and second other vehicles are the same, where the indicator value is defined as a function of the speed of the first other vehicle detected by the detection unit and the speed of the second other vehicle indicated by the information received by the communication unit. A determination unit determines whether or not the first and second other vehicles are the same on the basis of the indicator value calculated by the calculation unit.
