又は２記載の車両移動検出装置。[Scope of claim for utility model registration] (1) An ultrasonic transceiver attached to the front of the vehicle,
A stop state detection means measures and calculates the distance between the vehicle ahead and the own vehicle from the input/output of the transmitter/receiver when the stop state is detected, and detects the presence of the vehicle ahead when the distance is within a predetermined value. Then, if the distance is greater than the predetermined value within a predetermined time, the presence of the vehicle in front is determined, and if the vehicle is stopped, it is determined that the vehicle in front has started, and the distance between the two distances is determined as follows. A vehicle movement detection device comprising: control means for determining acceleration and energizing an alarm output device in response to the acceleration. (2) An ultrasonic transceiver attached to the front of the vehicle,
A stop state detection means measures and calculates the distance between the vehicle in front and the own vehicle from the input/output of the transmitter/receiver when the stop state is detected, and detects the distance in front when the distance is within a predetermined value for a predetermined duration. Determine the presence of a vehicle, and then determine the presence of the preceding vehicle when the distance is two distances greater than the predetermined value for another predetermined duration within a predetermined time, and if the vehicle is in the stopped state, 1. A vehicle movement detection device comprising: control means that determines that a vehicle ahead has started, determines acceleration during that time, and energizes an alarm output device in response to the acceleration. (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 detecting means detects a stopped state. Claim 1
Or the vehicle movement detection device according to 2.
