Abstract
Methods and systems for controlling shifting of a tandem axle assembly are described. In one example, a method comprises adjusting torque applied at an input connection of a first axle of a tandem axle assembly based on a clutch disengagement torque while transitioning the first axle between shift settings.
Claims20
A method, comprising:
- while transitioning a first axle of a tandem axle assembly between shift settings, adjusting torque applied at an input connection of the first axle based on a clutch disengagement torque.
A method, comprising:
- during a shift event of a tandem axle assembly including a first axle and a second axle:
- reducing torque applied at the first axle while concurrently increasing torque applied at the second axle;
- and
- oscillating the reduced torque applied at the first axle while maintaining the increased torque applied at the second axle.

A vehicle system, comprising:
- a tandem axle assembly including a first axle and a second axle;
- a first clutch engageable to couple the first axle to a first gearbox;
- a second clutch engageable to couple the second axle to a second gearbox;
- a controller with computer readable instructions stored on non-transitory memory that when executed, cause the controller to:
- transition the first axle of the tandem axle assembly between shift settings;
- and
- during the transition, adjust torque applied at the first clutch based on a disengagement torque of the first clutch.
