1. A system for monitoring a low-speed mobility vehicle and having a remote monitoring device adapted to be connected to the low-speed mobility vehicle through a communicator, comprising:

  • an acceleration sensor that is installed at the vehicle to produce an output indicative of acceleration acting on the vehicle;

    a counter that counts a number of times that each output of the acceleration sensor is equal to or greater than a predetermined value during a prescribed time period, wherein each output of the acceleration sensor is indicative of an acceleration component in one of X, Y, Z axis directions, and the counter counts the number of times that an output of at least one acceleration component exceeds a corresponding predetermined value in one of the X, Y, Z axis directions;

    a vehicle-stranding determiner that is installed at the vehicle and determines that the vehicle strands upon detecting that the counted number of times is equal to or less than a threshold value;

    a vehicle-strand-severity discriminator that is installed at the vehicle and discriminates a severity of the stranding of the vehicle in stages based on the detected acceleration of the vehicle when it is determined that the vehicle strands;

    a vehicle-stranded signal transmitter that is installed at the vehicle and transmits a vehicle-stranded signal indicating that the vehicle strands to the remote monitoring device through the communicator; and

    an informer that is installed at the remote monitoring device and informs to a predesignated information addressee in response to the signal that the vehicle is stranded.
