ANTI LOCK BRAKING SYSTEM (ABS)

ANTI-LOCK

BRAKING

SYSTEM (ABS)

INTRODUCTION

In addition to the conventional hydraulic brake

system, an Anti-lock Braking System

(ABS)

incorporating Electronic Brake Distribution

(EBD)

provided In TATA SAFARI STORME.

During a normal braking event EBD replaces the

Load Sensing Pressure Valve (LSPV) and limits

the level of braking force transmitted to the rear

wheels. The advantage of EBD over a LSPV is that

it can moderate the braking forces at the rear axle

depending upon the load condition and available

friction at the rear wheels.

During an emergency braking event the ABS

regulates the braking force for each individual

wheel. In doing so the system optimizes the level

of braking being achieved while maintaining a

stable, controllable vehicle. The EBD only acts on

the rear wheels, whereas the ABS is able to

control each wheel individually and can facilitate

pressure hold, release and increase cycles.

Both the EBD and the ABS functions work by

continuously monitoring and comparing the four

individual wheel speeds and reacts when a wheel

is detected as loosing grip with the road surface,

which happens when a wheel tends to lock during

braking.

The ABS is designed to be incorporated into the

circuits of the foundation brake system and will not

prevent the normal hydraulic operation of the

brakes in the event of an ABS failure.
