A method is performed for controlling a human-powered vehicle. The method includes calculating a first movement amount of the human-powered vehicle on a road from at least one of a rotational speed of a wheel of the human-powered vehicle and a rotational amount of the wheel. The method further includes calculating a second movement distance in an advancing direction of the human-powered vehicle and a horizontal direction from the first movement distance and a pitch angle of the human-powered vehicle and calculating a third movement distance related to movement in the advancing direction of the human-powered vehicle and a vertical direction from the first movement distance and the pitch angle. The method further includes predicting a terrain of the road from the second movement distance and the third movement distance.

Method for controlling human-powered vehicle and control device for human-powered vehicle

A control device is provided for a human-powered vehicle that includes a suspension and an operation detector detecting a first parameter correlated to a predetermined operation performed by a rider on the human-powered vehicle. The operation detector includes an acceleration sensor provided on at least one of a wheel axle of the human-powered vehicle and a portion of the human-powered vehicle closer to the wheel axle than a moving portion of the suspension. The first parameter includes acceleration in a fore-aft direction of the human-powered vehicle. The control device includes an electronic controller. The electronic controller is configured to determine the predetermined operation based on the acceleration in the fore-aft direction.
