| 摘要 |
The present invention relates to a method for use in dynamometer testing of a vehicle (100), the vehicle (100) including at least a first wheel shaft and at least one first vehicle power source for providing power to said first wheel shaft, said first wheel shaft being connected to a vehicle dynamometer system, said vehicle dynamometer system comprising a first controllable dynamometer power source (201) for providing power to said first wheel shaft, said first dynamometer power source being an electrical machine (201) comprising a stator and a rotor, said stator comprising a stator winding. The method includes: determining whether a first temperature (T1) is below a first temperature limit (Tlim1), and heating said electrical machine (201) by applying a current (Iheat) to said stator winding when said first temperature (T1) is below said first temperature limit (Tlim1). |
