CONTROLLER AND CONTROL METHOD

The present invention obtains a controller and a control method capable of simultaneously achieving freedom of driving and safety of a lean vehicle. In a controller () and the control method according to the present invention, a control section of the controller () can execute anti-lock braking operation for suppressing locking of a rear wheel () by increasing/reducing a braking force or drive power of the rear wheel () of a lean vehicle () and thereby controlling a slip degree of the rear wheel () to a slip degree target, and in the case where a slide request, which is a request by a rider to make the lean vehicle () slide, is present, implements a slide control mode in which the anti-lock braking operation is performed by setting the slip degree target to be higher than that of a case where the slide request is absent.
