The speed and mileage will be displayed on the instrument when the car is moving forward，Then the car will still display the speed when reversing？Will the odometer reading increase when reversing？
Brother Xiu thinks，This is a somewhat unpopular but interesting topic，Today I will give some seabet appanswers to the novice car enthusiasts。 Seabet
There are two ways to calculate car mileage，They are mechanical method and electronic speed sensor detectionMeasurement method.Early models used mechanical methods to calculate mileage，The principle is to know the wheel speed through the speed at the output end of the transmission system。But，This calculation method only calculates a single direction，In other words, only the forward direction is recorded。This kind of car will not display the speed when reversing，There is an anti-reverse device in the odometer，So the odometer value will not decrease。
The mileage calculation method of modern cars is detected through electronic speed sensors，Use Hall elements to detect the number of tire rotations to calculate mileage，without detecting the direction of tire rotation。In other words，As long as the wheels turn，No matter which direction it turns，There will be signal transmission and recording，So this is calculated into the mileage。So this kind of car will also display the speed when reversing，The odometer will also count normally，There will never be a phenomenon where the odometer value becomes less and less when driving in reverse。
What should you pay attention to if you refuse to reverse a car accident? 1. Vehicle blind spotThere is a tragedy，Say "I'm right by your side"，But you can’t see me”。How scary is the blind seabet iospot when reversing？In an accident caused by reversing，Mostly caused by the vehicle’s blind spot；Which hit、In an accident involving a child，Almost all caused by the existence of blind spots。Four blind spots: front and two corner areas、The area near the side of the car、The area below the rear windshield、C-pillar area on the right rear side of the body。2. Control vehicle speedBe sure to control the speed when reversing，Pay attention to whether there are vehicles or pedestrians passing by around you，And be ready to hit the brakes at any time。At the same time，Don’t spin in place，This will not only damage your car，And the directional assistance at this time will also become very heavy。
Warm reminder: Never step on the accelerator when reversing，Never step on the accelerator when reversing。Also，Parents traveling with their children，Be sure to take good care of your children！
