Electronic control of car
speed in cities

The idea may not be new, but so far no industry has mass-produced this component. Why is? As is well known, fixed speeds are specified on the routes in the cities and on the roads between two towns.

In numbers we find the 50 km/h, 70 km/h and 100 km/h as well as the well-known recommended speed of 130 km/h. It happens too often that car drivers ignore speed and you go faster than you would like.

The electronically controlled speed shouldn't be about asking the speeders to pay less, but rather that every driver protects his own safety and that of the occupants as best he can through responsibility and common sense. Our assistance systems are more modern and intelligent than ever. The emergency brake assistant in cities, which protects inattentive pedestrians when crossing a street. The spacer with laser that adapts to the speed of the vehicle in front. A rear-end collision is therefore no longer so easy. ESP so that the car does not skid when braking improperly and the driver retains control even in extreme situations.


That's all good, but it doesn't protect anyone from speeding. This article is intended to make it clear that with the support of GPS data and sophisticated map systems like the ones we have on the market today, an automatic speed limiter depending on where you are can be integrated into automobiles. All you have to do is retrofit a Wifi or Bluetooth module. Appropriate software can be programmed or an adjustment can be made to existing software from other areas. Spanish ? Still not quite sure what it's all about? OK, zero problem. You drive your car in the city, you flat out in every gear, but your car will never go faster than the legal limit in a city. In this case, according to the speedometer, your car is driving at 60 km/h, in real terms this would be a speed of 55-56 km/h. An upward tolerance is deliberately provided here. If you then move from a one-lane 50 km/h zone into a safe traffic area that is expanded to 2 lanes, then the permissible speed there will also be adjusted to 70 km/h. Your car can only drive a maximum of 80 km/h here. Incidentally, this also applies to all automobiles with two wheels. The scooter, the motorcycle, if the technology continues like this and the ever smaller drives then also for electric bicycles, with helmet, glove and kidney belt.


Your car communicates with your navigation device or smartphone via an integrated interface. After all, that's always there. You can also program your car in such a way that only your car can be set in motion with this registered smartphone. An additional hurdle to make theft more difficult. But there is still room for improvement here. If the dad of two growing children is just ready to give them the car keys, then Daddy can also individually adjust the maximum speed downwards. Unfortunately not upwards. Outside of built-up areas, a father can study the speed at which the chance of survival is highest, so he can then, for example, instead of starting at 100 km/h as standard, set the cars and driver profile to 80/km/h for the son and for them Daughter at 90 km/h. With the increasing number of kilometers and thus the gain in experience of each individual child, dad is reminded every few thousand kilometers whether the speed should be adjusted again, to the factory specifications in this case outside 130 km/h.


It doesn't matter who moves on the roads of this world in the future, even if he wants to, he can't drive faster. 2018 & 2019 were strong in terms of big city frenzy. Never before have so many innocent people died, including passengers, pedestrians or any other bystanders. Luckily it's always the others and you acquit yourself of everything.


So what does this change mean for the future? Cities are getting fewer signs again. We can see more of a city's natural beauty. Hasn't that happened to you too? You snap photos and in front of the most beautiful buildings there are the largest accumulations of any signs. Okay, a speed limit sign isn't going to rip everything out here either.


The speed signs all over Germany have disappeared. One less burden for an automobile driver to focus on. The taxpayer will be happy too. A few tens of millions swallow the signs determined over 10 years. Including maintenance, cleaning, replacement and installation. Even the employees of the city don't have to expose themselves to as much danger, although there may only be 10 or 20 people at a time setting up and carrying out maintenance work who are then involved in accidents, but even those would be history.

But there is more to look forward to in this context. The world loves green and eco more than ever. Since the production of signs is discontinued, the footprint in terms of “energy consumption” + “raw material consumption” + “chemical-based paint consumption” also shrinks. But the energy that all maintenance teams spend on signs in a year is also reduced. The time gained by no longer having to wait for signs ultimately means that employees also have less to do. This leaves more time for other things without having to hire more employees.


Although the focus here is on safety through the addition of a small component, the country's overall CO2 balance naturally benefits. No more extreme driving maneuvers with exorbitant acceleration are possible, the frenzy is over. Let others calculate how much energy can actually be saved here.


But the chain that we are building smaller with it also reaches into the areas where rescue workers have fewer accidents. The fire brigade rarely has to scrape torn cars off the road and find the torn off engine block 200m away. Of course, the many Raudis who die always leave one and the same disturbing picture with the emergency services that one has become accustomed to. With 2,000 traffic fatalities and an average of 5-15 helpers on site, 10,000 rescue workers can be healthier after work each year.

As so often, a small change is the key to a big change.

From 2024 it will be time. A law was introduced by the lawmaker to make these assistants available to everyone, albeit in a slightly modified form.
