Summary: | PROBLEM TO BE SOLVED: To reduce processing load of an ECU while detecting targets in a prescribed detection range without omission.SOLUTION: A target detection system for vehicle (10) comprises sensor units (1A to 1I) installed in prescribed parts of a vehicle (100) and a central control unit (20) connected to the sensor units by an in-vehicle bus (30). Each of the sensor units includes a sensor (11) for detecting targets around the vehicle and a sensor control unit (12) which generates target information of each of the targets detected by the sensor and transmits the target information to the central control unit via the in-vehicle bus. The sensor control unit determines which of a plurality of areas into which the peripheral area of the vehicle is divided each target detected by the sensor exists in, calculates a priority of each target on the basis of scores set to these areas, and is configured to transmit target information of targets of high priorities to the central control unit but not to transmit target information of targets of low priorities to the central control unit.SELECTED DRAWING: Figure 2
【課題】所定の検出範囲において物標を漏れなく検出しつつECUの処理負荷を軽減する【解決手段】車両用物標検出システム(10)は、車両(100)の所定箇所に設置されたセンサユニット(1A〜1I)と、センサユニットと車内バス(30)によって接続された中央制御ユニット(20)とを備え、センサユニットが、車両周囲の物標を検出するセンサ(11)と、センサによって検出された各物標の物標情報を生成して車内バスを介して中央制御ユニットへ物標情報を送信するセンサ制御部(12)とを有し、センサ制御部が、センサによって検出された各物標が、車両の周辺領域を複数に区画した複数のエリアのいずれに存在するかを判定し、これらエリアに設定されたスコアに基づいて各物標の優先度を計算し、優先度が高い物標の物標情報を中央制御ユニットへ送信するが優先度が低い物標の物標情報を中央制御ユニットへ送信しないように構成されている。【選択図】図2 |
