Electronic Brake Force Distribution Overview

Both Toyota Hilux Vigo and Toyota Fortuner come with Electronic Brake Distribution EBD. EBD is a braking system that adjusts to whatever situation you're in. Electronic Brake Distribution (EBD) gives you greater control and improved stability, which are especially useful when cornering or in an emergency. Unlike most braking systems, which distribute brake force through mechanical control, EBD applies brake force precisely through electronic control. It recognises that driving conditions, braking situations and vehicle weight distributions are unique and constantly changing. Working together with Anti-lock Braking System (ABS), EBD uses sensors to determine which wheels would provide maximum braking for the conditions – whether that's the front or rear wheels, the left or right. The final result is more precise and effective braking under all conditions.

The EBD control works with ABS, ensuring the most effective distribution of brake force between the brakes of the front and rear wheels.
When braking around a corner, it also controls the brake force on the left and right wheels, helping to maintain stability.
And where braking was controlled mechanically in the past, it is now controlled electronically by the ABS Electronic Control Unit (ECU).

How EBD Prevents Locking

Less chance of locking when braking in a straight line.

If you apply your brakes when driving in a straight line with a regular braking system, brake force is applied by mechanical control to all four wheels. This makes the rear wheels susceptible to locking, as they're under less real force than the front wheels
With EBD the brake force to the rear wheels is applied precisely by electronic control – reducing the chance of locking
This is achieved through the ABS ECU recognising this situation through signals from the speed sensor, which tells the ABS actuator to reduce the amount of brake force to the rear wheels.

Less chance of locking under load

EBD even adjusts the amount of brake force on your brakes according to whether or not you're carrying a load, again reducing the chance of locking
It does this by varying the amount of brake force applied to the rear wheels according to changes in load due to load shifting or deceleration.

EBD senses the weight of your load and any movements it makes while braking – applying the correct amount of brake force for better control and stability.

Less chance of locking around corners.

If you apply your brakes when taking a corner with a regular braking system, almost equal brake force is applied to the inner and outer wheels. This makes the inner wheels susceptible to locking, as they are under less real force than the other wheels
With EBD the brake force to the inner wheel is applied precisely by electronic control – reducing the chance of locking
This is achieved through the ABS ECU recognising the situation through signals from the speed sensor. This tells the ABS actuator to reduce the amount of brake force to the inner wheel.
