CONTROLLER AND CONTROL METHOD

The present invention obtains a controller and a control method capable of achieving appropriate cornering during cruise control of a straddle-type vehicle. In the controller and the control method according to the present invention, during the cruise control, in which acceleration/deceleration of the straddle-type vehicle is automatically controlled without relying on an accelerating/decelerating operation by a driver, a vehicle speed of the straddle-type vehicle is restricted to be equal to or lower than an upper limit speed at the time of turning, an exit of a curved road is detected on the basis of a predicted route of the straddle-type vehicle, and a magnitude of the deceleration of the decelerated straddle-type vehicle is reduced at a time point before the straddle-type vehicle reaches the exit.
