Document Type and Number:
WIPO Patent Application WO/2019/208080
Kind Code:
A1
Abstract:
A rough road determination device is provided with a posture information acquisition unit (61), a drive information acquisition unit (62), and a rough road determination unit (63). On the basis of a signal of a posture sensor (21) installed in a vehicle (A), the posture information acquisition unit acquires posture information which indicates a posture change of the vehicle. The drive information acquisition unit acquires drive force information which indicates a state of a drive force which acts on the vehicle. In the case where the posture change indicated by the posture information exceeds a threshold value (Vth) in a state in which the drive force indicated by the drive force information is stable, the rough road determination unit determines that the vehicle is running on a rough road.
