Deceleration levels of vehicle during uphill/downhill braking
Deceleration levels of vehicle during uphill/downhill braking
(OP)
Hi,
During downhill braking/uphill braking, as per the mathematical calculation, depending upon the slope angle, the deceleration will decrease of increase as sin(theta) component of vehicle weight.
Is there a mechanism which will ensure the max. deceleration level of vehicle in downhill/uphill braking as it is in plain road!!
Thanks,
Elongo

I suspect that none of them actually answers the question you intended to ask.
But you have gathered a knowledgeable crowd, who probably could be a lot more helpful if you would expand a bit on what, exactly, you are trying to figure out.
We cannot see what is right in front of you, so it's up to you to paint an illuminative word picture of your problem.
Do not be afraid to use more words, or to attach or embed an illustration or photograph.

If available tire traction on the hill and the level is equal, I don't think so.

Uphill is a different story and it should be fairly easy to achieve an even better braking distance than level ground with the same traction.

In plain road condition, max braking deceleration(in terms of g) * safety margin considered for the calculation. In FE analysis, reaction due to braking applied as inertial acceleration on the whole structure with minimum support condition on the tire patch.
For uphill/downhill braking, similar to the discussion happened over here, there was an internal discussion, whether to consider the values accounting sin(slope) or plain road values. Hence posted this query...
Meanwhile from internal vehicle testing team got the communication that the effect of slope has to be accounted.Hence with that we proceeded with the calculation.Hope, I clarified the details.
