The present invention obtains a controller and a control method capable of improving a rider's perceptibility of a warning.

A controller (51) for a rider-assistance system (50) mounted to a straddle-type vehicle (100) includes: a determination section that determines necessity of the warning given to the rider; a haptic motion performing section that performs haptic motion at least once to reduce or increase acceleration/deceleration of the straddle-type vehicle (100) only for a moment; and an acquisition section that acquires travel state information of the straddle-type vehicle (100). The haptic motion performing section changes a priority of each wheel (3, 4) at the time of changing a braking force to reduce or increase the acceleration/deceleration only for the moment in the haptic motion according to the travel state information acquired by the acquisition section.

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.

A bicycle braking system includes a server, a portable device such as a smartphone, a display unit, a control unit, a power supply unit, a rotating electrical machine, and a bicycle. The portable device includes an image display unit, a braking condition transmitting unit, and a braking condition setting unit. The control unit regeneratively brakes the bicycle using the rotating electrical machine in accordance with the braking condition set by the braking condition setting unit. The braking system enables a non-user to set braking conditions for the bicycle and to perform braking based on the conditions set by the non-user.
