Description

上記した課題を解決すべく、本開示に係るセンサシステムは、第１の物理量を検出すべき第１のセンサであって第１のセンサの動作を規定する第１のパラメータの設定を受けるべき第１のセンサと、第２の物理量を検出すべき第２のセンサであって第２のセンサの動作を規定する第２のパラメータの設定を受けるべき第２のセンサと、路面の状況を判断する判断部と、判断部により判断された路面の状況下で、検出された第２の物理量に基づき、予め定められたテーブルを参照することにより、第１のセンサに第１のパラメータを設定し、かつ、検出された第１の物理量に基づき、予め定められたテーブルを参照することにより、第２のセンサに第２のパラメータを設定する連携処理部と、を含む。 In order to solve the above-described problems, a sensor system according to the present disclosure provides a sensor system that is a first sensor that should detect a first physical quantity and that should receive the setting of a first parameter that defines the operation of the first sensor. 1 sensor, a second sensor that is to detect a second physical quantity and that is to receive the setting of a second parameter that defines the operation of the second sensor, and a road surface condition. a determination unit; and a first parameter set in the first sensor by referring to a predetermined table based on the second physical quantity detected under the road surface condition determined by the determination unit ; and a cooperation processing unit that sets a second parameter for the second sensor by referring to a predetermined table based on the detected first physical quantity.

本開示に係るセンサシステムによれば、前記路面の状況が判断された下で、前記第１のセンサが前記第１の物理量を検出することができなくても、前記第１のセンサに前記第１のパラメータを設定することができ、同様に、前記第２のセンサが前記第２の物理量を検出することができなくても、前記第２のセンサに前記第２のパラメータを設定することができる。 According to the sensor system according to the present disclosure, even if the first sensor is unable to detect the first physical quantity after the road surface condition is determined , the first sensor detects the first physical quantity. Similarly, even if the second sensor cannot detect the second physical quantity, the second parameter can be set for the second sensor. can.
