A motorcycle (300) includes a clutch lever (14), a clutch switch (15) configured to detect whether or not the clutch lever (14) is gripped, a vehicle speed sensor (16) configured to detect a vehicle speed, a hydraulic rear brake (18), a pressurizing unit (17) configured to perform a pressurizing process that applies an oil pressure to the rear brake (18), and a microcontroller (19) configured to control the pressurizing process by the pressurizing unit (17) based on results of the detection by the vehicle speed sensor (16) and the clutch switch (15).

A braking force control apparatus in a motorcycle, includes a controller which controls a transmission to reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel of a vehicle, a clutch between the engine and the transmission, and brake devices which generate braking force on the wheels. The vehicle is switchable between a normal and a slow speed driving modes. In the slow speed mode the controller detects an inclination pitching angle θ, and causes the brake devices to generate braking force on at least one of the drive wheels when θ≧a predetermined value, then starts switching the clutch to a connected state when a driving operation is input, and gradually releases the braking force once driving force starts to be transmitted to the drive wheel.

A brake control device includes an electronic controller that is configured to control a braking unit that is configured to brake at least one of a plurality of rotating bodies of a human-powered vehicle. The electronic controller is configured to control the braking unit upon determining an ABS control is performed to decrease a braking force of a first rotating body included in the plurality of rotating bodies so that a braking force of a second rotating body, which is different from the first rotating body and included in the plurality of rotating bodies, is increased by a force that is different from hydraulic pressure.

A method for carrying out autonomous braking in a two-wheeled motor vehicle, where the necessity of vehicle deceleration is detected with the aid of a surround sensor system. When vehicle deceleration is necessary, prior to its execution, a test braking action independent of a rider and of a predefined temporal length is carried out. During or after the execution of the test braking action, a rider readiness variable characterizing the readiness of the rider to master the vehicle deceleration detected as necessary is ascertained. After completion of the test braking action, the vehicle deceleration is initiated, the time characteristic of the vehicle deceleration being a function of the rider readiness variable.
