CPC H02P 21/14 (2013.01) [B60L 15/20 (2013.01); B60K 1/02 (2013.01); B60L 2240/423 (2013.01)] | 6 Claims |
1. A vehicle comprising:
a main motor for traveling; and
an electronic control unit that controls the main motor, the electronic control unit being configured to:
extract, from time series data of a rotation speed of the main motor, vibration data in a predetermined frequency band that includes resonance frequency of a drive system that includes the main motor;
lower an upper limit value of output torque of the main motor from a normal upper limit value to a first upper limit value lower than the normal upper limit value when magnitude of vibration obtained from the vibration data exceeds a first threshold value; and
lower the upper limit value of the output torque of the main motor from the first upper limit value to a second upper limit value lower than the first upper limit value when the magnitude of the vibration exceeds a second threshold value larger than the first threshold value.
