14 Claims

1. A method of controlling a dog clutch configured to engage at least one gear of a gearbox by a gear actuator having a DC motor, the DC motor configured to move the dog clutch via an actuator arm, the method comprising:

supplying the DC motor with a pulse width modulated voltage having a duty cycle provided by a control algorithm, the control algorithm comprising a trajectory planner generating a desired position of the actuator arm based on a 4^thorder trajectory planning algorithm and a motion controller for tracking a desired position of the actuator arm, the 4^thorder trajectory planning algorithm includes integrating a derived profile four time; and

moving the dog clutch by the DC motor via an actuator arm based on the pulse width modulation voltage, the dog clutch configured to engage the at least one gear.
