When the driver presses the brake pedal, the HBA system detects the speed and force of the pedal application and, if it determines that the driver is trying to brake as hard as possible, it will automatically increase the brake pressure. This can help to reduce the stopping distance of the car and prevent a collision.
HBA is a valuable safety feature that can help to reduce the risk of accidents. It is standard equipment on many new cars, and it can be retrofitted to older cars by some auto repair shops.
