Claims (1)

[Scope of claim for utility model registration] (1) An ultrasonic transceiver attached to the front of the vehicle,
A stationary state detecting means, a seat pressure detecting means, a seat inclination degree detecting means, and when the stationary state, a predetermined seat pressure, and a predetermined seat inclination degree are detected, the vehicle ahead and the own vehicle are detected from the input/output of the transmitter/receiver. The presence of the preceding vehicle is determined when the distance is within a predetermined value, and the presence of the vehicle ahead is determined when the distance is determined to be within a predetermined value. - A vehicle movement detection device characterized by comprising: a control means that determines that the preceding vehicle has started if the seat pressure and seat inclination are in the state, and energizes an alarm output device. (2) An ultrasonic transceiver attached to the front of the vehicle,
A stationary state detecting means, a seat pressure detecting means, a seat inclination degree detecting means, and when the stationary state, a predetermined seat pressure, and a predetermined seat inclination degree are detected, the vehicle ahead and the own vehicle are detected from the input/output of the transmitter/receiver. The presence of the preceding vehicle is determined when the distance is within a predetermined value for a predetermined period of time, and the presence of the preceding vehicle is determined when the distance exceeds the predetermined value for a predetermined period of time. A vehicle movement detection device comprising: control means for determining that the preceding vehicle has started if the vehicle in front of the vehicle is stopped, has the same seat pressure, and has the same seat inclination degree, and energizes an alarm output device. (3) The vehicle further includes a start operation detection means, and the control means determines that an alarm is unnecessary when the start operation detection means detects a start operation even if the stop state detection means detects a stop state. The vehicle movement detection device according to claim 1 or 2.
