Document Type and Number:
Japanese Patent JP3952898
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent hindrance on traveling from occurring even in an initial state when a vehicle is traveled and to accomplish the prevention by simple work.
SOLUTION: The vehicle 1 is provided with a traveling driving means 15 which can be driven by inputting electric power from a first power source 25; second power sources 43 attached to wheels 4, 7; transmitter 44 attached to the wheels 4, 7, detecting states of tires 18 of the wheels 4, 7 by inputting the electric power from the second power source 43 and capable of transmitting the detection signal at a predetermined sending time interval Dt corresponding to predetermined various kinds of sending modes 1-3; and a receiving indicator 46 for inputting the electric power from the first power source 25, receiving the detection signal and indicating the state of the tire 18. In the case that the state of the tire 18 based on the detection signal is in a state of less than a predetermined value, the sending time interval Dt is further shortened.
