Braking looks very easy but more components are being added to make braking better.
Hello🙋🏽♂️ everyone It's me again still talking about braking system.
EBD's are part of ABS. That help in distributing braking power to all wheels of the car. They ragulateand apply braking force needed to each wheel according to road condition, vehicle's load and vehicle's speed (remember the eye illustration I gave in the ABS where I said "different wheels at different speeds gets different pressure). They ensure how mush braking force is needed by each wheel and applies the same force in order to achieve the most suitable braking impact, they detect how much weight is be g supported by each wheel, they change the amount of braking pressure sent to each wheel on an instant.
EBD & ECU determines the slip ratio of each wheel. If the EBD notice that the front wheel are in danger of slipping maybe bacause of having more load like when someone is coming back from home depot with alot of woods loaded in the trunk of his Toyota Yaris and the rear of the car is so low and the front is high like someone did a bad suspension adjustment. The high front will raise the front tyre from the ground, EBD applies less braking force to the back while maintaining or increasing the pressure on the back wheel.
EBD's are useful in turns: when turning a car, the outer wheels tend to have a wider and faster rotation than the inner wheels. If too much brake force is applied to the inner wheel, it might cause an oversteer and even lock the wheel causing control loss. The EBD senses slip on the inner wheel and reduce brake force on them without reducingvthe force on the outer wheel.
How do EBD make all these possible.
- Speed Sensors
- Brake Force Modulators
- ECU.
Let me Explain
The speed sensors calculates the speed of the car engine and the speed of the wheel as the speed of them might not be the same and than may cause skidding. They also calculate the slip ratio and sends the information to the ECU (a small chip which collects the data from the speed sensors in each wheel and uses the data to calculate the slip ratio (slip ratio is the difference between the car speed and the tyre rotation)
Brake Force Modulators pumps brake fluids into the brake lines and activate the brake cylinders: meaning that the brake force of each three can be controlled.
These components work together to make the EBD work.
That's it for EBD.
THANKS FOR YOUR TIME.
