Abstract
An apparatus and method for diagnosing damage to drive-train hardware of a vehicle in which a disconnector may obtain speed of an auxiliary drive wheel motor of the vehicle and speed of a main drive wheel motor of the vehicle and determines damage to the drive-train hardware including the disconnector that controls whether to interrupt delivery of power through engagement or disengagement between auxiliary drive wheel motor-side drive-train hardware and auxiliary drive wheel-side drive-train hardware, based on whether a difference between the speed of the auxiliary drive wheel motor and the speed of the main drive wheel motor exceeds a threshold value, Accordingly, preventing divergence of motor RPM by diagnosing damage to the drive-train hardware of the vehicle.
Claims20
An apparatus of diagnosing damage to drive-train hardware of a vehicle, the apparatus comprising:
- a sensor configured to obtain speed of an auxiliary drive wheel motor of the vehicle and speed of a main drive wheel motor of the vehicle;
- and
- a controller electrically connected to the sensor and configured to determine the damage to the drive-train hardware including a disconnector configured to control whether to interrupt delivery of power through engagement or disengagement between auxiliary drive wheel motor-side drive-train hardware and auxiliary drive wheel-side drive-train hardware, according to whether a difference between the speed of the auxiliary drive wheel motor and the speed of the main drive wheel motor exceeds a threshold value,
- wherein the controller is configured to:
- determine a defect in a system configured to control the disconnector, based on at least one of a position of a sleeve of the disconnector, a position of a fork of the disconnector, or a current of a motor configured to control the disconnector;
- and
- determine that the drive-train hardware is not damaged, when the controller concludes that the system configured to control the disconnector is defective.
A method for diagnosing damage to drive-train hardware of a vehicle, the method comprising:
- obtaining, by a sensor, speed of an auxiliary drive wheel motor of the vehicle and speed of a main drive wheel motor of the vehicle;
- determining, by a controller electrically connected to the sensor, damage to the drive-train hardware including a disconnector configured to control whether to interrupt delivery of power through engagement or disengagement between auxiliary drive wheel motor-side drive-train hardware and auxiliary drive wheel-side drive-train hardware, according to whether a difference between the speed of the auxiliary drive wheel motor and the speed of the main drive wheel motor exceeds a threshold value;
- determining, by the controller, a defect in a system configured to control the disconnector, based on at least one of a position of a sleeve of the disconnector, a position of a fork of the disconnector, or a current of a motor configured to control the disconnector;
- and
- determining, by the controller, that the drive-train hardware is not damaged, when the controller concludes that the system configured to control the disconnector is defective.
