Embodiment Construction
[0010] exist figure 1 In the test vehicle, drive the chassis dynamometer, carry out vehicle pre-inspection and input the information of the tested vehicle, set the wheel power with a small load when the vehicle speed is 70km / h in a linear relationship, and set The ratio of the drum speed to the actual maximum power point corresponding to the vehicle speed, and automatically determine whether the capacity of the chassis dynamometer can meet the test requirements. If the capacity of the chassis dynamometer can meet the test requirements, start wheel power scanning, otherwise the tested vehicle Exit the test; use the torque adjustment method to scan the wheel power, record the maximum wheel power and its corresponding vehicle speed; when the ratio of the wheel power scan to the drum speed and the corresponding vehicle speed of the maximum power point obtained by scanning reaches the set value, the end During the power scanning process, it automatically switches to the smoke test ...
