Abstract: The test platform for electric vehicle driving motor system was introduced, and according to this, the noise experiments of hybrid electric vehicle were carried in condition of different torque with rated speed based on sound array and analysis sysytem. The results show that the noise intensity is lower at low frequencies, relative increase in middle frequency, and relatively unchanged at high frequencies.
Key words: hybrid electric vehicle; motor; sound array; noise
