an inclination angle detection means, a stopped state detection means, and when the stopped state is detected, measures and calculates the distance between the preceding vehicle and the own vehicle from the input and output of the transmitter/receiver, and the distance corresponds to the inclination angle. The presence of the preceding vehicle is determined when the distance is within a predetermined value that has been increased, and if the vehicle is stopped when it is determined that the distance exceeds another predetermined value that is larger than the predetermined value, the preceding vehicle is detected. A vehicle movement detection device comprising: control means for determining that the vehicle has started and energizing an alarm output device. (2) An ultrasonic transceiver attached to the front of the vehicle,
An inclination angle detection means, a stopped state detection means, and when the stopped state is detected, the distance between the vehicle in front and the host vehicle is measured and calculated from the input/output of the transmitter/receiver, and the distance is determined by the inclination angle during a predetermined duration of time. determines the presence of the preceding vehicle when the amount is within a predetermined value that has been increased and corrected in accordance with
After that, when it is determined that the distance exceeds another predetermined value that is larger than the predetermined value for a predetermined duration, if the vehicle is stopped, it is determined that the preceding vehicle has started, and the warning output device is activated. A vehicle movement detection device comprising: means. (3) The vehicle further includes a starting operation detecting means, and the control means determines that an alarm is unnecessary when the starting operation detecting means detects a starting operation even if the vehicle speed detecting means detects a stopped state. Claim 1
Or the vehicle movement detection device according to 2.
