Anti lock braking system ppt

ABS can modulate the pressure to the brake as often as 15 times per seconds ABS precisely controls the slip rate of the wheels to ensure maximum grip force from the tyre and it there by ensures maneuverability and stability of the vehicle. When the brakes are applied, fluid is forced from the brake master cylinder outlet ports to the HCU inlet ports. The control unit receives signals from the typical sensors plus a yaw, lateral acceleration G- force and a steering angle sensor. Normally the modulator is made up of solenoid that open and close valves Solenoid valves The solenoid valves are located in the modulator unit and are electrically operated by signals from the control module.

Published by Alan Phelps Modified over 3 years ago. Normally the ABS warning light will turn on and let the driver know there is a fault. Reducing wheel vraking improves vehicle stability and control during braking, since stability increases as wheel slip decreases.

ABS(Antilock braking system)

PUMP Since the valve is able to release pressure from the brakes, there has to be some way to put that pressure back. ABSs can improve vehicle control during braking, lcok reduce stopping distances on slippery split or low coefficient of friction road surfaces by limiting wheel slip and minimizing lockup. If you wish to download it, please recommend it to your friends in any social system.

The hydraulic control unit is a separate unit The system prevents wheel lock up during an emergency stop by modulating brake pressure. This is accomplished by closing the valve to resist p;t pressure from the brake pedal.

Normally the modulator is made up of solenoid that open and close valves Solenoid systme The solenoid valves are located in the modulator unit and are electrically operated by signals from the control module. It may be of integral type and non integral type. In order to view it, please contact the author of the presentation. Moving something by means of a liquid water or oil under pressure.

A detailed control system used in ABS is shown in Figure. The control unit receives signals from the typical sensors plus a yaw, lateral acceleration G- force and a steering angle sensor.

These problems commonly occur on vehicle with conventional brake system which can be avoided by adding devices called ABS If there is an ABS failure, the system will revert to normal brake operation.

If you wish to download it, please recommend it to your annti in any social system. Automatically changes to Flash or non-Flash embed. An ABS consists of several key components: Presentation Description No description available. ABS provides greater vehicle stability and control during hard braking lockup to the driver.

Registration Loci your password? By preventing the wheels from locking, it enables the driver to maintain steering control and to stop in the shortest possible distance under most conditions.

Antilock Braking System (ABS) |authorSTREAM

The primary rear circuit of the brake master cylinder feeds the front brakes. This principle reduces the amount of work required by the user. Registration Forgot your password?

If that wheel is still decelerating, it opens the solenoid valve for that circuit. So the car slides out of control With ABS system, the driver can brake hard, take the evasive action and still be in control of the vehicle in any road condition at any speed and under any load.

To make this website work, we log user data hraking share it with processors. After a valve release the pressure supplied from the user, the pump is used to restore a desired amount of pressure to the braking system.

The release and reapply of the brake pedal will avoid the locking of the wheels which in turn avoid the skidding. We think you have liked this presentation. This prevents any more fluid from entering that circuit.
