Electronic Braking System for Cars

[Auroshis]

Is there a scope for replacing the conventional hydraulic braking
systems of cars by an entirely electronically integrated braking
system...thereby enabling the maneuvering of the speed of the car by
sensors controlled system.....Sensors as similar to those used in Self-
parking systems for the cars......By this we could avert accidents
caused by the sudden stop or brakes applied by vehicles at the time of
crisis....

What's the matter with the electrically actuated hydraulic powered brakes
used for anti-lock brakes and traction control?

Their advantage is that they will stop the car when all power assist
has failed.

Well, you push on the "brake pedal" and that pressurizes the hydraulic
fluid, which presses the pads against the disks, and that stops the
car. Which happens even if the power assist pump is dead, and even if
the ABS electronics is dead, and even if one of the hydraulic lines is
cut.

You'll have to push harder than you're used to, depending on how much
accessory stuff has failed.

Well dats fine.....but the ABS systems n all come to play only when
the tyre starts slipping and loses traction or so....
My query was to cant we have a brakin system electeonically
controlled...which wud b governinn the speed of the car in case it
comes too close wid the vehicle ahead of it...so that if the vehicle
give a sudden break the sensors sense its stop nd accordingly apply
the brakes in tym avoidin a collision....

You can, but the system has to be sufficiently reliable that it prevents
more accidents than it causes. It also has to be affordable.

There have been lots of radar-based anti-collision systems designed; I
think one is actually available on some luxury car now. Sure, they are
electronic, but they interface to the hydraulic braking system.

I think some aircraft braking systems are all-electric, at least some
prototypes are. You might google that.
