Re: [Speed-dreams-devel] Trac ticket #97: Many cars have too much (unrealistic) brake pressure

[Wolf-Dieter B. <wd...@wd...>]

The robots are coded to use a max brake pressure of 30000 as normal value (For TRB1 cars the value used is about 40000, in TORCS the trb1 class was restricted to have a max at 40000 last year).

The normal way a robot brakes is pressing 0.5 * max brake pressure.
While learning it may increase the pressure, if noticed, that the target speed was not reached while braking.

Knowing that there is a factor 2 caused by the front rear repartition, the max brake value used at a brake is 30000 / 4 = 7500. So this is not far away from real world data.

The first issue caused by a too much restricted max brake pressure is, that the robots cannot stop in the pit. And this is what happens here.
