Electrical Engineering/Automated Halt Mechanism on Brakes Failure


QUESTION: Dear Prof Cleggsan

Is the following automated system can be designed and developed in a four wheeler i.e. Car, Jeep, Truck etc  ?.

Example :

Driver is driving the vehicle at 160 Km/Hr speed on a highway.
Suddenly he/she realizes that the brakes have failed now in this case the driver has to use his all driving skills to avoid collisions and accidents.

The Automated System designed will slowly and gradually halt/stop the automobile even in case of brakes failure.

Another way is "Prevention is better than cure". A instrument control Panel indicating the possibility of brakes wear and tear out.

Is it possible to automate the motion stop operation in event
of vehicle brakes failure ?

Awaiting your reply,

Thanks & Regards,

ANSWER: These ideas have been tried and used in various vehicles over the past several years.  There are some heavy duty trucks that have automatic sensing of brake failure and bring about slow down or special warnings to the driver.  Many automobiles now have warning lights that instruct the driver the brakes are nearly worn down and the vehicle should go into the shop for repair and maintenance.

Automobile makers are always trying out such ideas and techniques to see if they have market appeal and make their products more competitive in the marketplace.

So, I don't see anything your proposal that would be an original thought to any of the auto companies of the world.

QUESTION: Dear Prof Cleggsan

Thank you.

Is it possible to automate the motion stop operation in event of vehicle brakes failure ?.

The 4 Wheeler engine stops working automatically when brakes fail resulting in stop / halt function but what about the speed ?.

Slowly and Gradually we have to slow down the vehicle. Otherwise applying brakes at 100 km/hr, 120 km/hr, 150 km/hr, 200 km/hr speed will result in ?.

The Driver's speed will vary from 40 km/hr, 60 km/hr, 80 km/hr, 100 km/hr, 120 km/hr, 150 km/hr, 200 km/hr etc

Awaiting your reply,

As before, yes, there are many such schemes used over the years.  But, there are safety issues as well as cost increases in the manufacturing of the vehicle.

With high electronic content and microprocessing now in just about every vehicle on the road it is easy to add but the question is its contribution to the overall improvement of vehicular performance and implementations.

The breaking or slowing activity must be somewhat intelligent by sensing the road conditions.  For example, on steep and curving highways the stopping or slowing action may need to be much more severe than on straight highway with no incline or nearby traffic conditions.

Good Luck.
