Rear suspension assembly and method of controlling a rear suspension assembly

A snowmobile comprising:

• a chassis including a tunnel;
• a motor connected to the chassis;
• at least one ski connected to the chassis;
• an endless drive track disposed at least in part below the tunnel and operatively connected to the motor for propulsion of the snowmobile;
• a rear suspension assembly supporting and tensioning the endless drive track, the rear suspension assembly including:
• a front suspension arm having an upper end and a lower end, the upper end of the front suspension arm being pivotably connected to the tunnel;
• a rear suspension arm having an upper end and a lower end, the upper end of the rear suspension arm being pivotably connected to the tunnel;
• a pair of slide rails pivotably connected to the lower end of the front suspension arm and to the lower end of the rear suspension arm;
• a first rear shock absorber connected between the front suspension arm and the pair of slide rails, the first rear shock absorber biasing the pair of slide rails away from the tunnel;
• and
• a second rear shock absorber connected between the rear suspension arm and one of the front suspension arm and the pair of slide rails;
• at least one sensor for sensing an angular position of one of the front suspension arm and the rear suspension arm relative to one of the tunnel and a component of the rear suspension assembly near at least one of the front suspension arm and the rear suspension arm, the at least one sensor being operatively connected to one of:
• the tunnel, and
• the rear suspension assembly;
• a wire harness connected to the at least one sensor, the wire harness passing through the tunnel;
• and
• a controller communicatively connected to the at least one sensor via the wire harness to receive electronic signals therefrom representative of the angular position of the one of the front and rear suspension arms.
