Clutch engagement ratio detection

A method for determining a clutch condition for a vehicle having at least a front wheel and a rear wheel, a motor, a transmission, and a clutch coupling the motor to the transmission, the method comprising:

• determining, with a controller, an output transmission speed;
• determining, with the controller, an input transmission speed;
• determining, with the controller, a transmission speed ratio by comparing the output transmission speed to the input transmission speed;
• determining, with the controller, a currently engaged gear in the transmission;
• extracting a gear speed ratio associated with the currently engaged gear from a stored set of gear ratios;
• determining, with the controller, a clutch engagement ratio by comparing the transmission speed ratio to the gear speed ratio;
• determining, with the controller, a clutch condition based on the clutch engagement ratio;
• receiving, at the controller, a signal associated with a current acceleration and comparing the current acceleration to an expected acceleration;
• and
• confirming, with the controller, the clutch condition based on the comparison of the current acceleration and the expected acceleration.
