Portable device and vehicle

Abstract

A portable device communicates with a vehicle, and the portable device includes: a motion sensor; a control unit configured to determine whether or not abnormality has occurred in the motion sensor, based on an output from the motion sensor; and an output unit configured to perform an output representing abnormality in the motion sensor, when the control unit determines that abnormality has occurred in the motion sensor.

What is claimed is: 
     
         1 . A portable device that communicates with a vehicle, the portable device comprising:
 a motion sensor;   a control unit configured to determine whether or not abnormality has occurred in the motion sensor, based on an output from the motion sensor; and   an output unit configured to perform an output representing the abnormality in the motion sensor, when the control unit determines that the abnormality has occurred in the motion sensor, wherein   the output unit performs wireless communication to transmits, to either or both of the vehicle and another portable device, abnormality notification as the output representing the abnormality in the motion sensor.   
     
     
         2 . The portable device according to  claim 1 , wherein
 in a case where the control unit determines that the abnormality has occurred in the motion sensor, and the portable device is outside a range in which the portable device is capable of performing wireless communication with the vehicle, the output unit does not perform wireless communication to transmits the abnormality notification to the vehicle.   
     
     
         3 . The portable device according to  claim 2 , wherein
 in a case where the control unit determines that the abnormality has occurred in the motion sensor, and the portable device is outside the range, the output unit performs wireless communication to transmits the abnormality notification to the vehicle when the portable device enters the range for the immediately following time.   
     
     
         4 . The portable device according to  claim 1 , wherein
 in a case where the control unit determines that the abnormality has not occurred in the motion sensor, and the motion detected based on an output from the motion sensor matches any of one or more predetermined patterns, the control unit performs a process based on the pattern which the motion matches.   
     
     
         5 . The portable device according to  claim 4 , wherein
 in a case where the control unit determines that the abnormality has not occurred in the motion sensor, and the motion matches any of the one or more predetermined patterns where notification to the vehicle is necessary to perform the process based on the pattern, the control unit causes the output unit to transmit, to the vehicle, notification based on the pattern which the motion matches.   
     
     
         6 . A portable device that communicates with a vehicle, the portable device comprising:
 a motion sensor;   a control unit configured to determine whether or not abnormality has occurred in the motion sensor, based on an output from the motion sensor; and   an output unit configured to perform an output representing the abnormality in the motion sensor, when the control unit determines that the abnormality has occurred in the motion sensor, wherein   the control unit causes the motion sensor to perform a predetermined test operation in a case where an output from the motion sensor indicates that the portable device is stationary for a predetermined time period or longer time period, and   whether or not the abnormality has occurred in the motion sensor is determined based on a result of the test operation.
