Diagnostic systems and methods of a continuously variable transmission

A vehicle, comprising:

• a plurality of ground-engaging members;
• a power source supported by the plurality of ground-engaging members;
• a continuously variable transmission (CVT) comprising a drive belt, a drive member, and a driven member, wherein:
• the an output shaft of the power source is operably coupled to the drive member,
• an output shaft of the CVT is operably coupled to the plurality of ground-engaging members, and
• the drive belt operably couples the drive member and the driven member;
• a sensor that detects at least one of an engine-based parameter or a driveline-based parameter of the vehicle;
• and
• a controller operably coupled to the sensor and configured to:
• determine, based on an output of the sensor, whether a remaining life of the drive belt is below a threshold;
• and
• when it is determined the remaining life of the drive belt is below the threshold, limit function of the power source more than it was before it was determined the remaining life of the drive belt is below the threshold.

A method for vehicle control of a vehicle comprising a belt-driven continuously variable transmission (CVT), the method comprising:

• obtaining, from a sensor configured to detect at least one of an engine-based parameter or a driveline-based parameter, sensor data;
• determining, based on the sensor data, whether a remaining life of a drive belt of the CVT is below a threshold;
• and
• when it is determined the remaining life of the drive belt is below the threshold, limiting function of a power source of the vehicle more than it was before it was determined the remaining life of the drive belt is below the threshold.
