This system is a precision braking system used in modern automobiles.
Automobile Engineering tutorials
Components of an ABS:
1. Wheel speed sensor.
2. ABS control module.
3. Hydraulic motor.
4. Pressure release valves.
5. Brake pipe leading to caliper.
Working of ABS:
Engineering tutorials
All the wheels are fixed with brake calipers and wheel speed sensors. As the brake is
applied, the hydraulic motor supplies the flow to the brake caliper and the brake will be engaged. In case of a wheel slip, there is a chance for wheel lock. This will be sensed by the wheel speed sensor which intimates this to the ABS control module. The ABS control module intern opens the relief valve and release the pressure from the caliper there by avoiding wheel lock. As the wheel lock is cleared, the hydraulic motor increased the flow there by increasing the breaking effort.
There are two types of ABS systems
1. Three channel
2. Four channel system.
Which will be updated in my coming videos.
