Abstract: The present invention obtains a controller capable of improving safety of a motorcycle. The controller that controls vehicle body behavior of the motorcycle includes: an acquisition section that acquires trigger information generated in accordance with peripheral environment of the motorcycle; and an execution section that initiates a control mode making the motorcycle execute an automatic brake operation in accordance with the trigger information acquired by the acquisition section and makes the motorcycle generate a braking force. The acquisition section further acquires deceleration resistance information that is information related to a driver's driving posture on the motorcycle, and the execution section changes a control command that is output in the control mode in accordance with the deceleration resistance information acquired by the acquisition section.

Abstract: An object is to improve mountability of a brake system to a straddle-type vehicle while considering safety. In a brake system, a mechanism portion includes a friction applying device which brakes a wheel of a straddle-type vehicle with a frictional force corresponding to a movement of an operator, an operator movement sensor which detects the movement of the operator, and an actuator which is unitized with the friction applying device. During normal braking, a control unit controls an output of the actuator based on a detection result of the operator movement sensor to change the frictional force applied to the wheel by the friction applying device. Further, when the actuator is in a non-energized state, the friction applying device applies a frictional force to the wheel.

Abstract: The present invention obtains a hydraulic pressure control unit capable of saving a space where a device can be mounted in a straddle-type vehicle. In the hydraulic pressure control unit according to the present invention, a controller includes a brake control section that controls operation of a component for controlling a brake hydraulic pressure generated in the straddle-type vehicle, and the brake control section is accommodated in a case that is held by a base body. The controller further includes a power control section that controls operation of a power generator for the straddle-type vehicle, and the power control section is accommodated together with the brake control section in the case.
