GENERAL
OUTLINE OF CHANGE
D The following service procedures have been established to correspond to the addition of an EBD
(Electronic Brake force Distribution) function to the ABS-ECU.
EBD (Electronic Brake force Distribution)
The EBD operates during braking within the range where the slip ratio is relatively low and the ABS
does not normally operate. The input signals from the vehicle speed sensors are used to detect the
amount of slip in the rear wheels. This is then used to control the solenoid valves in the ABS hydraulic
unit so as to limit the rear wheel hydraulic pressure in order to prevent the rear wheels from locking.
Because the amount of slip in the rear wheels is directly monitored by the ABS-ECU, it allows the braking
force to be optimised in accordance with the road conditions (such as road surface m and gradient)
and the laden condition of the vehicle, and also makes it possible to shorten braking distances by improving
the braking performance even when the brake pad m is low.
