Can anyone suggest a good way to implement a low (i.e. 56kph/35mph) speed limiter that is activated with a switch or button push?
From my research, I see 4 options, but if someone else has already solved this, I would like to learn from you.
1. Write a permanent value into cruise control, so that when cruise is set, it defaults to that stored speed, rather than to the current road speed.
Why not do this? Not sure it is possible to have a permanent value. Otherwise could be a good option. Not 100% ideal for a race car to keep going at a speed without the driver pressing the throttle.
2. Map switching to a map that has a speed limit enabled.
Why not do this? Map switching is not as simple as 1 button press / hard to keep track of which map you are in during a race situation
3. Set speed limiter to the target value (i.e. 56kph/35mph) and then have a switch to feed MSS54 a fake (lower speed) value for normal driving/racing use - then switch to the real road speed input value to cause the limiter to become active
Why not do this? Could be a good option - still requires driver to keep their foot on the throttle, doesn't matter what gear. Would DME set a plausibility fault if it sees the speed input change too rapidly?
4. Some way to implement is via Sport mode...?
Why not do this? Seems like this is clumsy - driver needs to be in a specific gear, and it isn't a true speed limiter, just makes it harder to go too fast.
