Abstract
A method of operating an electrified vehicle having a front axle disconnect is provided. A powertrain supervisor controller determines that the electrified vehicle needs to be secured due to an internal reason. The powertrain supervisor controller determines whether a front axle status is one of faulted or disengaged. The powertrain supervisor controller requests, based on the front axle status being faulted, engagement of an electronic park brake when securement conditions are active. A message indicative of a front axle disconnect status is displayed at a human machine interface.
Claims13
A method of operating an electrified vehicle having a front axle disconnect, the method comprising:
- determining, at a powertrain supervisor controller, that the electrified vehicle needs to be secured due to an internal vehicle reason;
- determining, at the powertrain supervisor controller, whether a front axle status is one of faulted or disengaged;
- requesting, by the powertrain supervisor controller, and based on the front axle status being faulted, engagement of an electronic park brake when securement conditions are active;
- and
- displaying, at a human machine interface, a message indicative of “the vehicle not in park condition”.
A control system for operating an electrified vehicle, the control system comprising:
- a front axle disconnect that selectively engages and disengages relative to a front drive axle of the electrified vehicle;
- a human machine interface configured to display messages to a vehicle operator based on operating status of the front axle disconnect;
- an electronic park brake;
- and
- a powertrain supervisor controller configured to:
- determine that the electrified vehicle needs to be secured due to an internal vehicle reason;
- determine whether a status of the front axle disconnect is one of faulted or disengaged;
- request, based on the front axle disconnect status being faulted, engagement of the electronic park brake;
- and
- communicate a signal to the human machine interface to display a message indicative of “the vehicle not in park condition”.
