The disclosure relates to a brake system for a baby or child vehicle, and more particularly, to a brake system for a baby or child vehicle, in which the movement of the vehicle is controlled by locking a brake while an occupant is getting off the vehicle, and automatically releasing the brake in only a case where it is checked that the occupant is getting on the vehicle, thereby preventing a falling accident caused by the movement of the vehicle when the occupant gets on or off the vehicle or while a toddler stands up on the vehicle.

The present invention obtains a controller and a control method capable of executing automatic cruise operation that suppresses failure of a friction brake mechanism for a rear wheel.

A controller for a motorcycle according to the present invention includes a mode change section that changes a mode to a first mode in a state where a temperature of a rear-wheel friction brake mechanism is lower than a first prescribed temperature and to a second mode in a state where the temperature of the rear-wheel friction brake mechanism is higher than the first prescribed temperature during automatic deceleration in the automatic cruise operation. In the case where the braking forces generated on the rear wheel in the first mode and the second mode are compared under a condition that the same deceleration is generated in the motorcycle by the automatic deceleration, in a state where the deceleration is at least less than a first reference amount, the braking force generated on the rear wheel in the second mode is smaller than the braking force generated on the rear wheel in the first mode.
