5) Hydraulic Circuit of HBA
The above figure shows one front and one rear wheel and the same hydraulic circuit forms as in the ESP
operation. When HECU recognizes that it is an emergency and it is required for hard braking, depending
on the pressure value of the brake pressure sensor and pressure changes caused by the pressure sensor
timing, it operates the pump immediately to apply the brake pressure at the wheels. Then, the pressure in
the pump increases until just before the corresponding wheel gets locked. The motor still keeps rotating
and the outlet valve and the separation valve will stay closed. When the wheel starts to lock, the HBA
function cancels and switches to ABS operation.
