00:00When driving, the speed of the car on the dashboard
00:02Why is it always faster than the GPS navigation app?
00:05Which number is actually more accurate?
00:07It doesn't matter if you don't understand. It's useless to understand.
00:09Do you understand?
00:10As far as I know, the speedometer of a car is calculated according to the speed of rotation of the tires per second
00:14And the speed of rotation of the gearbox
00:17And the factors such as wind speed, tire size will also affect the calculation
00:20The principle of GPS speed is relatively simple
00:23It is calculated according to the average distance traveled by the vehicle in the past few seconds
00:27So the speed of navigation is closer to reality
00:30In addition, according to international standards
00:31It is allowed for the speedometer of the car to be slightly higher than the actual speed
00:35And it must not be lower than the actual speed
00:37Different car manufacturers may have different ways of tuning
00:40In general, the speed displayed on the car cannot exceed one-tenth of the actual speed
00:44Plus 14 kilometers per hour
00:46For example, the actual speed is 120 kilometers per hour
00:48The car speedometer can only display 136 kilometers per hour
00:52But this is just a general reference formula
