Rough Road Traveling Determination Device And Abnormality Determination Device
Abstract: A rough road traveling determination device 2 for determining whether a vehicle has travelled a rough road is provided with: a vehicle speed moving average calculation unit 22 for calculating a short-term moving average and a long-term moving average of vehicle speeds of the vehicle; a determination parameter calculation unit 23 for calculating an integrated value which is obtained by integrating the absolute value of the difference between the short-term moving average and the long-term moving average of the vehicle speed, in a monitoring period corresponding to the vehicle speed; a fluctuation observation unit 24 for counting the number of times a large-small relationship between the short-term moving average and the long-term moving average of the vehicle speed is reversed in the monitoring period; and a rough road determination unit 25 that, when the integrated value is greater than a preset first threshold value and the number of times is greater than a preset second threshold value, determines that the vehicle has travelled a rough road.
