Document Type and Number:
Japanese Patent JP7420778
Kind Code:
B2
Abstract:
A vehicle includes an engine, a continuously valuable transmission which has an endless belt, speed-changes and outputs a power from the engine, and a transmission apparatus to which the power speed-changed by the continuously valuable transmission is transmitted. If the vehicle's travel speed is not smaller than a first threshold value and an accelerator opening degree is not smaller than a second threshold value, a control unit determines that the continuously valuable transmission is being used in a belt high-load situation. If a travel distance in the belt high-load situation is not smaller than a third threshold value, the control unit determines that the endless belt is deteriorated or deterioration thereof is in an advanced stage, and a deterioration message about the endless belt is displayed in a display under an instruction from the control unit. A situation in which a speed changing ratio of the continuously valuable transmission is not greater than a fourth threshold value may be determined as the belt high-load situation.
