How is a car's mileage calculated?
2 Answers
Car mileage is calculated based on the number of rotations of the tires. The mileage is computed by sensors and the car's computer, then displayed on the odometer. Car mileage refers to the total distance the vehicle has traveled, shown on the dashboard. The methods to reset the mileage are: 1. Press the black button next to the dashboard; 2. Remove the dashboard and its internal components, then adjust the mileage gear using tools. To check the car's mileage, look at the odometer on the dashboard, indicated by 'odo' with the unit 'km' following the number. Its purpose is to inform the driver of the distance traveled.
My years of driving experience have taught me that a car's mileage is calculated by sensors that monitor the rotation of the wheels in real time. Each time a wheel completes a full rotation, the vehicle's system calculates the distance traveled based on the tire's circumference, accumulating the data like a small calculator and displaying it on the dashboard. For example, modern cars often use ABS sensors or speed sensors to capture wheel pulse signals, processing data with precision down to the second to ensure the mileage accurately reflects the actual distance traveled. When the mileage increases rapidly, I also need to pay attention to maintenance reminders, such as changing the oil or inspecting the suspension system after every 10,000 kilometers. If a sensor malfunctions and provides inaccurate readings, it could mislead maintenance schedules and affect the car's condition. In short, mileage isn't just a number—it helps optimize daily driving habits to ensure smooth trips, and when selling the car, accurate mileage can enhance its valuation and prevent losses.
