1. A tire pressure drop detecting method, comprising the steps of:
- detecting rotational angular velocities of tires provided for a vehicle,discriminating whether the vehicle is in a state of autocruise traveling or not, andexecuting a pneumatic pressure drop judging processing for autocruise traveling based on the detected rotational angular velocities when it is discriminated that the vehicle is in a state of autocruise traveling.

Abstract
A tire pressure drop detecting method, which executes a pneumatic pressure drop judging processing for autocruise traveling when the vehicle is in a state of autocruise traveling. It is judged based on a front/rear acceleration of the vehicle whether the vehicle is in a state of autocruise traveling or not. Furthermore, the pneumatic pressure drop judging processing for autocruise traveling is performed by using a judging threshold value which is set to become smaller as the speed of the vehicle becomes larger.
