[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.
