Abstract:
1. A brake controlling apparatus for a motorcycle wherein an operation amount applied to each brake operation device for front and rear wheels is detected by an electronic control unit and fluid pressures are generated by fluid pressure modulators for the front and rear wheels based on the detection values and then braking force is generated for brake apparatus for the front and rear wheels by the fluid pressures, wherein: said electronic control unit causes said brake apparatus for the front and rear wheels to be operated such that: when said brake operation device for the front wheel is operated, said brake apparatus for the front wheel generates braking force for the front wheel in response to an operation amount of said brake operation device for the front wheel and causing said brake apparatus for the rear wheel, which is not operated, to generate braking force for the rear wheel that interlocks with the operation amount of said brake operation device for the front wheel; wherein, during a first interval in which the operation amount of said brake operation device of the front wheel changes from zero to a first predetermined value, the braking force for the front wheel increases gradually and the braking force for the rear wheel gradually increases irrespective of a brake operation of the rear wheel; wherein, during a second interval in which the operation amount of said brake operation device of the front wheel changes from the first predetermined value to a second predetermined value that is higher than the first predetermined value, gradually increasing the braking force for the front wheel while keeping the braking force for the rear wheel to a maximum value in the first interval; and increasing or decreasing, within a period from a beginning of the first interval to an end of the second interval, a rate of increase of the braking force for the front wheel with respect to the operation amount to increase or decrease a deceleration of the vehicle so as to vary substantially linearly with respect to an increase of the braking force of the brake for the front wheel.
