A system for determining if a tire of a vehicle is improperly inflated. The system includes a radar (145), a wheel speed sensor (125), and a controller (150). The radar (145) is configured to emit a signal generally parallel to a surface the vehicle is traveling on, to detect a reflection of the signal off of an object positioned perpendicular to the vehicle, and to output an indication of a speed of the vehicle. The wheel speed sensor (125) is configured to sense a speed of a wheel (105) of the vehicle. The controller (150) is coupled to the radar (145) and the wheel speed sensor (125), and is configured to receive the indication of the speed of the vehicle from the radar (145), to calculate a speed of the vehicle based on the sensed speed of the wheel (105), and to determine a tire of the wheel is improperly inflated when the speed of the vehicle calculated using the wheel speed sensor varies by more than a predetermined amount from the speed of the vehicle determined using the radar signal. |
