1. A tire failure detection device comprising:
a steering angle sensor for sensing a steering angle;
a yaw rate sensor for sensing a yaw rate; and
a control unit, wherein
the control unit calculates side-slip energy based on an output signal of the steering angle sensor and an output signal of the yaw rate sensor, and
the control unit determines that a failure has occurred in a tire when the side-slip energy exceeds a first threshold.
