System Features and Components
The AHB system is composed of the hydraulic power unit, the brake actuation unit, and electric stability control.
The Hydraulic Power Unit generates the hydraulic pressure required for braking.
Similar to the boosting effect when the driver steps on the brake pedal in a system equipped with a vacuum booster, the hydraulic pressure stored in the cylinder is supplied to provide pressure throughout the entire brake line.
The brake actuation unit delivers pressure that is generated by the Hydraulic Power Unit to a caliper on each wheel via electric stability control. It is connected to the brake pedal to detect the brake force that is required by the driver, and to generate a brake feeling.
Electric stability control carries out the ABS, TCS, and ESC functions as in conventional vehicles.
