[0046] Examples:
[0047] 1. Meteorological conditions such as temperature measurement: the temperature during the test was 30°C, and the breeze (<2m / s).
[0048] 2. Adjust the tire pressure: adjust the tire pressure to 220kPa recommended by the vehicle manufacturer under cold conditions.
[0049] 3. Configure the vehicle mass to m 1 : The test vehicle rides a driver, and then loads sandbags to make the vehicle mass reach the maximum design total mass of the vehicle 2050kg.
[0050] 4. The mass of the vehicle is m 1 Carry out the taxiing test and record the data under the conditions: Carry out 5 sets (round trip as a set) taxiing test on the level, dry asphalt road, the initial speed is 50km / h, and the portable GPS device (sampling frequency 10Hz) is used to record each taxiing test 10 vehicle speed-time curves are obtained by vehicle speed-time curve and sliding distance.
[0051] 5. Configure the vehicle mass to m 2 : After unloading all the sandbags, only one driver is left. The mas...
