Monitoring system for vehicle

摘要

In a monitoring system for a power wheelchair (low-speed mobility vehicle) and having a remote monitoring device connected to the wheelchair through a communicator, it is determined whether the wheelchair strands based on detected acceleration, and when it does, a vehicle-stranded signal that the vehicle strands is transmitted to the remote monitoring device through the communicator and predesignated information addressees including a dealer, a data terminal owned by the operator's family and emergency assistance providers such as the police or hospital are informed in response to the signal that the vehicle is stranded, thereby enabling to respond rapidly and appropriately when the wheelchair becomes stranded.

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.
