Abstract
A method according to an exemplary aspect of the present disclosure includes, among other things, controlling a vehicle in response to a diagnostic test performed to detect an incorrect cable connection of the vehicle.
Claims19
A method, comprising:
- running a diagnostic test using a vehicle diagnostic system of a vehicle to detect an incorrect cable connection of the vehicle including communicating a torque excitation signal to an electric machine of the vehicle and detecting the incorrect cable connection based on a speed response signal from the electric machine;
- and
- controlling the vehicle in response to detecting the incorrect cable connection.
A vehicle control method, comprising:
- running a diagnostic test including:
- communicating a torque excitation signal to an electric machine of a vehicle;
- and
- processing a speed response signal from the electric machine to identify whether an incorrect cable connection exists between the electric machine and a second vehicle component;
- and
- controlling the vehicle in response to detecting the incorrect cable connection.
3 more elements
A vehicle diagnostic system, comprising:
- an electric machine;
- an inverter;
- three-phase cables that connect said electric machine to said inverter;
- and
- a control unit configured to execute a diagnostic test to detect an incorrect connection of said three-phase cables, the diagnostic test including communicating a torque excitation signal to said electric machine and detecting said incorrect connection based on a speed response signal from said electric machine.
