Why is car electronics showing incorrect values?

The dashboard of our cars does not always give us accurate information, but few people think about it. It is true that modern vehicles have different equipment as well as innovative assistance systems, but some figures are not accurate.

Let's see why this is happening?

Incorrect speed

It is unlikely that someone does not know that in absolutely every car the speedometer does not show the actual speed. It should be noted that the device shows slightly higher values ​​than it actually is.

Oddly enough, this is required by the standards of most states and is done for safety. For this reason, the real speed is corrected by 6-8 km / h more, which is 5-10% higher in percentage than the real speed.

Mileage error

Unfortunately, the odometer works the same way. It measures the number of wheel revolutions and the dashboard shows the vehicle's mileage. The mechanical part of the meter also gives incorrect information in the range of 5-15% of the actual mileage.

These figures also depend on the diameter of the wheels. And if the car is equipped with larger tires, then the readings will also be incorrect, but not with a plus, but with a minus. If you have driven 60 km with large wheels, the actual mileage is 62 km (depending on the difference in the odometer cable settings and the diameter of the new wheels).

Fuel level

The fuel gauge is just as good at lying to us because the remaining fuel readings are almost never true. Some drivers also suffer from this problem, which is the most common because they cannot accurately calculate how much fuel they have left. And so they risk getting stuck on the road.

The main role in this case is played by the fuel system - it has different sizes and its filling leads to errors in instrument readings. In addition, the fuel level gauge is not one of the most accurate, but many manufacturers find its average values ​​sufficient.

Do not rely entirely on the performance of electronic devices. But at the same time, do not think that she always gives you the wrong information. Most of the devices in the car show real data, and if not, it will be average or close to reality.
