This control device for motor cycle comprises: a lean angle detection unit which detects the lean angle of a motorcycle; a throttle grip opening degree detection unit; a throttle valve control unit which controls a throttle valve; a brake control unit which controls a font wheel brake and a rear wheel brake; and a control unit which controls the throttle valve control unit and the brake control unit, wherein the control unit controls the throttle valve, the front wheel brake, and the rear wheel brake during a turn travel of the motorcycle. The control unit applies the rear wheel brake harder than the front wheel brake during the turn travel of the motorcycle.

A method and system for determining a maximum cornering braking threshold for a motorcycle includes determining an absolute lean angle with respect to horizontal and a relative lean angle for the motorcycle relative to a road surface. The maximum cornering braking threshold is determined from at least the absolute lean angle and the relative lean angle. The maximum cornering braking threshold is used to provide stability during motorcycle cornering. A multi-dimensional look-up table stores different maximum cornering braking thresholds that correspond to different combinations of absolute lean angles and relative lean angles. The relative lean angle is determined by processing video data from a video sensor. Values for additional conditions, such as motorcycle speed, wheel slip coefficient, steering angle, mue and type of road way are stored in the multi-dimensional look-up table to assist in determining the maximum cornering braking threshold.
