automobiles safety features - EBD,ABS and ESP

ELECTRONIC BRAKE DISTRIBUTION

Electronic brake distribution is a technology made as a safety function in automobiles that improves a vehicle’s braking performance and works in combination with an antilock brake system or ABS. EBD enables the braking force of a vehicle to be increased or applied automatically, depending on road conditions, speed of the vehicle, weight of vehicle.

 

In a car with no EBD or simple braking system, when the brake pedal is applied the brake fluid travels from the master cylinder to the brake cylinders. When the fluid goes inside the brake cylinder, the pressure of the fluid being applied forces the two pistons to push out resulting in the brake shoes or pads being pushed out. This push or pressure is in direct proportion to the push by the pistons, which causes the shoes or pads to rub against the drum or caliper. This reaction creates friction and decreases the turning of the wheels.
An electronic brake-force distributor is the computer-controlled device it electronically monitors, through sensors, the conditions of the road, pressure on the brake pedal, and vehicle weight .After monitoring EBD calculates the needed amount of braking force to be applied on the vehicle’s front and rear wheels which provides the maximum safe amount of braking force to the wheels without the risk of too much stopping power and provide better and more precise braking under every condition.
Centre of gravity of cars shifts forward when you apply brake this creates a reduction in grip which can cause the rear wheels to lock. Electronic brake force distribution uses the solenoid valves in the ABS unit to regulate the braking power at the rear wheels. This ensures maximum braking performance at the front and rear wheels and, under normal conditions, prevents the rear end from swerving out because of over-braking at the rear.

ANTI-LOCK BRAKING SYSTEM

Any vehicle can lose its directional stability and steering control when the wheel locks and tire skids. The antilock brake system fitted to automobile brakes keeps the brakes from locking up during braking and with ABS it becomes easy to steer during braking. Under some driving conditions you may find it difficult to get the brake force you want without causing one or more of the wheels to lock.

Anti-lock braking systems (also called ABS) are made to sense the speed of the wheels on a vehicle. An abnormal drop in wheel speed, which indicates potential wheel lock, causes the brake force to be reduced to that wheel. This is how the anti-lock braking system prevents tire skid and the accompanying loss of steering control. This improves vehicle safety during heavy brake use or when braking with poor traction.

ELECTRONIC STABILITY PROGRAM

An electronic stability program (ESP) is an active safety system that reduces the risk of a driver losing control of the vehicle. Also known as electronic stability control (ESC), ESP builds upon features such as anti-lock braking systems (ABS) and traction control to stabilize the vehicle when it changes direction from that intended by the driver. ESP helps you remain in control of your vehicle when you skid, swerve suddenly or when road conditions change.

 

Electronic Stability Program reduces the risk of vehicle from crashes by correcting impending over steering or under steering, stabilising the vehicle during sudden evasive manoeuvres example: swerving and by improving traction on slippery or icy roads.
