Abstract: A braking force control apparatus for a saddle ride vehicle includes a transmission controller which reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel, a clutch device which connects—disconnects the driving force between the engine and the transmission, a brake device which generates braking force on the drive wheel, and a sensor which detects a state of the transmission. The transmission switches between a neutral state and an in-gear state, and when the sensor detects that the transmission is switching from the neutral state to the in-gear state, the controller causes the brake device to generate braking force on the drive wheel, and then releases the braking force upon completion of the switching to the in-gear state.

Abstract: 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 ?, and causes the brake devices to generate braking force on at least one of the drive wheels when ??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.
