The EBD system (Electronic Brake force Distribution) as a
sub-system of the ABS system is to control the maximum braking
effectiveness by the rear wheels.
It further utilizes the efficiency of highly developed ABS
equipment by controlling the slip of the rear wheels in the partial
braking range.
The brake force is moved even closer to the optimum and
controlled electronically, thus dispensing with the need for the
proportioning valve.
The proportioning valve, because of a mechanical device, has
limitations to achieve an ideal brake force distribution to the rear
wheels as well as to carry out the flexible brake force distribution
proportioning to the vehicle load or weight increasing. And in the event
of malfunctioning, driver cannot notice whether it fails or not.
EBD controlled by the ABS Control Module, calculates the slip
ratio of each wheel at all times and controls the brake pressure of the
rear wheels not to exceed that of the front wheels.
If the EBD fails, the EBD warning lamp (Parking brake lamp) lights up.
Advantages
–
Function improvement of the base-brake system.
–
Compensation for the different friction coefficients.
Failure Diagnosis
1.
In principle, ESC and TCS controls are prohibited in case of ABS failure.
2.
When ESC or TCS fails, only the failed system control is prohibited.
Description
AFLS Unit(ECU)
AFLS located in Cockpit Module is provided information of vehicle (steering wheel signal,vehicle speed, inclination of vehicle).
Based on provided information , it calculates algorithm and adjust Low beam of H/Lamp.
It transmits driving information by using LIN protocol, it is
operated in Fail-safe reaction mode
Description
BSD is a system that uses two magnetic wave radar sensors
attached on the rear bumper to measure the distance from the following
vehicles and provides the sensing and (visual and auditory) alarm of any
vehicle coming into the blind spot.
