Connect/disconnect system and method for operating the system for electric vehicle

A system for an electric vehicle, the system comprising:

• a drive axle configured to drive a set of vehicle wheels;
• a motor configured to selectively drive the drive axle;
• a sensor configured to measure a vehicle speed;
• a coupling configured to move between an open position in which the motor and the drive axle are disconnected from each other and a closed position in which the motor and the drive axle are connected to each other;
• and
• a controller in communication with the motor, the sensor, and the coupling, the controller configured to:
• determine a modification value based on the measured vehicle speed and a first vehicle operating parameter;
• determine whether the modification value is negative;
• adjust a second vehicle operating parameter by the modification value in response to the modification value being negative;
• determine a vehicle speed connect value based on the adjusted second vehicle operating parameter;
• and
• move the coupling to the closed position in response to the vehicle speed connect value being greater than the measured vehicle speed.

A method comprising:

• determining a modification value based on a measured vehicle speed and a first vehicle operating parameter;
• determining whether the modification value is negative;
• adjusting a second vehicle operating parameter by the modification value in response to the modification value being negative;
• determining a vehicle speed connect value based on the adjusted second vehicle operating parameter;
• and
• moving a coupling to a closed position in response to the vehicle speed connect value being greater than the measured vehicle speed, the coupling connecting a motor and a drive axle to each other when in the closed position.
