Claim Text:
1. An abnormality detection device for a continuously variable transmission, the abnormality detection device comprising: a setting module that sets a target gear ratio for the continuously variable transmission based on an operation amount of an accelerator and a vehicle speed; a calculation module that determines an input torque to the continuously variable transmission from an output torque of an engine, obtains a generated driving force of a power unit including the engine and the continuously variable transmission according to the input torque to the continuously variable transmission and the target gear ratio set by the setting module, and calculates an acceleration of a vehicle based on the generated driving force of the power unit and a running resistance; and a determination module that determines the target gear ratio to be abnormal in the case where the acceleration of the vehicle calculated by the calculation module is lower than or equal to a predetermined value.
