4)"Brake Assist System" that provides power assisted braking at times of insufficient emergency braking

[Research and Development Aim]
On motorcycles, the brakes are not simply for slowing and stopping. Controlling the front and rear brakes independently can also be used as a way of controlling the movement and attitude of the machine. In order to perform this function, the brakes on a motorcycle operate independently for front and rear. This has been true on most motorcycles for a long time.

On the other hand, during emergency braking to avoid an accident, there are cases where the optimum use of the machine's braking capacity is not fully used, either because only one brake is applied or because insufficient pressure is applied despite the use of both brakes. Taking this tendency into consideration, this system was developed to help achieve both the independent control capability in normal riding and effective application of braking force during emergencies.


[Features of the System]
This system works in combination with an ABS system. A sensor that detects changes in brake fluid pressure is used to sense the characteristics of the braking force being applied by the rider. The assist requirement is determined separately for the front and rear brakes and even if the rider is applying force to only one of the brakes, if the braking characteristics indicate to the ECU that it is an emergency braking situation, the system functions to automatically apply braking force to both the front and rear brakes in a way that makes full use of the machine's braking potential.
