Target detection apparatus and vehicle control system |
摘要 |
A target detection apparatus counts the number of reflection points, taking a reflection point of interest as being a target reflection point, for each detected reflection point, the reflection points being present in a target area that is set with reference to the target reflection point and each having a difference in speed from the target reflection point, the difference being not more than a preset identical speed determination threshold, and extracts a parallel-running pair that is a pair of the reflection points that meet preset parallel-running conditions. The target detection apparatus determines that the two reflection points configuring the parallel-running pair originate from an identical target, when a count value is not less than a preset size determination threshold, the count value being of at least either of the two reflection points configuring the extracted parallel-running pair and generates target information reflecting the determination results. |

1. A target detection apparatus that is mounted to a vehicle, and receives reflected waves of radar waves transmitted towards the outside of the vehicle to generate information related to a target that has reflected the radar waves, the target detection apparatus comprising:
a processor, the processor being configured to: transmit and receive radar waves to detect the position of a reflection point that has reflected the radar waves; generate information related to a target that has reflected the radar waves, according to the position of the reflection point detected; count the number of reflection points, taking a reflection point of interest as being a target reflection point, for each reflection point detected, the reflection points being present in a target area that is set with reference to the target reflection point and each having a difference in speed from the target reflection point, the difference being not more than a preset identical speed determination threshold; extract a parallel-running pair that is a pair of the reflection points that meet preset parallel-running conditions; determine that the two reflection points configuring the parallel-running pair originate from an identical target, when a count value is not less than a preset size determination threshold, the count value being derived from the number of reflection points counted for at least either of the two reflection points configuring the parallel-running pair extracted; and generate target information reflecting that the two reflection points configuring the parallel-running pair are determined to originate from the identical target. |
