What does 'trip' on the dashboard mean?
2 Answers
The 'trip' on the car dashboard represents the trip mileage, which can be used to record the distance traveled for each trip. Here is a related introduction to the car odometer: 1. The tachometer is usually located inside the instrument panel, placed symmetrically with the speedometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. The car odometer includes two LCD digital display windows connected to the same signal source, which respectively accumulate the current trip mileage and the total mileage. The current trip mileage typically has four digits for short-term counting and can be reset. The total mileage has six digits and cannot be reset. The accumulated mileage numbers in an electronic odometer are stored in non-volatile memory, preserving the data even when there is no power. 2. The car odometer is usually located directly in front of the driver's position. A typical mechanical odometer is connected to a flexible shaft containing a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn drives a magnet inside the odometer's housing to rotate. The housing is connected to the pointer and, through a hairspring, positions the pointer at zero. The speed of the magnet's rotation causes changes in the size of the magnetic lines of force, disrupting the balance and thereby moving the pointer.
I've been driving for over 20 years. The trip button on the dashboard is the trip odometer, specifically recording the total distance since you started the car this time. I reset it every time after refueling—just press the reset button next to the steering wheel lightly to zero it out. Then, by the next refuel, I can check how many kilometers I've driven and divide by the fuel consumption to know the mileage. This is very practical for planning trips, like calculating the mileage and budgeting time for weekend outings in advance. Unlike the total mileage, which is permanently accumulated and doesn't change, the trip odometer can monitor driving habits to prevent wasting money on fuel and detect abnormalities, such as increased distance due to brake failure. Developing a habit of regular resets can enhance safety awareness.
