The present invention is provided with a CAN input unit (travel speed input unit) for inputting the travel speed of a vehicle, and sprung acceleration input units (first sensor input unit and second sensor input unit) for inputting the signal fluctuation range (vibration level) of a sprung acceleration sensor. The ECU includes a first determination unit. And a first determination unit that determines whether the traveling speed of the CAN input unit is equal to or greater than a first threshold value (first speed), and that determines whether the traveling speed is equal to or greater than a second threshold value (second speed) as a sprung acceleration sensor value (first sensor input value) of a sprung acceleration input unit (e.g., sprung acceleration input unit) of the first sensor input unit or as a sprung acceleration sensor value (second sensor input value) of a sprung acceleration input unit (e.g., sprung acceleration input unit) of the second sensor input unit. The signal fluctuation range of one of sprung acceleration sensor values (a second sensor input value) of a sprung acceleration input unit is smaller than the first fluctuation range and smaller than the signal fluctuation range of the other one of the sprung acceleration sensor values (a second sensor input value) of the sprung acceleration input unit.
具有输入车辆的行驶速度的CAN输入部(行驶速度输入部)和输入簧上加速度传感器的信号变动幅度(振动等级)的簧上加速度输入部(第一传感器输入部、第二传感器输入部)。ECU具备第一判断部,该第一判断部判断CAN输入部的行驶速度是否为第一阈值(第一速度)以上、且作为第一传感器输入部的簧上加速度输入部(例如,簧上加速度输入部)的簧上加速度传感器值(第一传感器输入值)或作为第二传感器输入部的簧上加速度输入部(例如,簧上加速度输入部)的簧上加速度传感器值(第二传感器输入值)中的一方的信号变动幅度是否小于第一变动幅度且小于另一方的信号变动幅度。
