Document Type and Number:
Japanese Patent JP5494886
Kind Code:
B2
Abstract:
The invention provides a vehicle having an obstacle detection device capable of improving the control accuracy of a motor and preventing the influence of noise on a sensor. A vehicle includes motors 31 and 32 which are AC motors, an inverter 2 that drives the motors, an ultrasonic sonar 1 which is, for example, a detector for detecting an obstacle around the vehicle, a frequency determining device 6 which determines whether noise generated from the inverter 2 is likely to interfere with a detection frequency of the detector, and a sonar ECU 5 which changes the carrier frequency of the inverter 2 when it is determined that the noise is likely to interfere with the detection frequency.
