Influence Of Driving Torque On Tyre Noise


Even while at a standstill, motors of electric vehicles are generating high tyre torques leading to an increase in tyre/road noise of up to 10 dB in the near field. To reduce such driving torque-dependent tyre noise, systematic tests were carried out on the acoustically optimised inner drum test rig at Institute of Vehicle System Technology at the Karlsruhe Institute of Technology.
