CONTROLLER AND CONTROL METHOD

The present invention obtains a controller and a control method capable of appropriately executing automatic emergency deceleration operation of a straddle-type vehicle. In the controller according to the present invention, when the automatic emergency deceleration operation of the straddle-type vehicle is executed, at a braking start time point at which a braking force starts being generated on at least one of wheels, braking force distribution between the front and rear wheels is brought into an initial state where the braking force is generated on the front wheel. In the control method according to the present invention, when the automatic emergency deceleration operation of the straddle-type vehicle is executed, at the braking start time point at which the braking force starts being generated on at least one of the wheels, the braking force distribution between the front and rear wheels is brought into the initial state where the braking force is generated on the front wheel.
