Abstract
A method for controlling a power tailgate in a vehicle power tailgate system includes steps of controlling operation of a motor to attempt to lower or raise a tailgate operably connected to the motor, determining that a clutch interposed between the motor and the tailgate (and operably connected to the motor and the tailgate) slipped by at least a predetermined slip amount during operation of the motor to attempt to lower or raise the tailgate and, responsive to the determination that the clutch slipped by at least the predetermined slip amount, generating an alert indicating a need for manual reset of the tailgate.
Claims18
A method for controlling a power tailgate in a vehicle power tailgate system, the method comprising steps of:
- controlling operation of a motor to attempt to raise a tailgate operably connected to the motor from a fully open position to a fully closed position;
- determining that the tailgate is currently in the fully closed position;
- responsive to a determination that tailgate is currently in the fully closed position, discontinuing operation of the motor;
- determining that a difference between a number of motor rotation edges expected to occur during operation of the motor to raise of the tailgate from the fully open position to the fully closed position, and a number of motor rotation edges that occurred during operation of the motor to attempt to raise the tailgate from a fully open position to a fully closed position, is greater than or equal to a predetermined tolerance value;
- and
- responsive to the difference being greater than or equal to the predetermined tolerance value, generating an alert indicating a need for manual reset of the tailgate.
A method for controlling a power tailgate in a vehicle power tailgate system, the method comprising steps of:
- controlling operation of a motor to attempt to lower the tailgate from a fully closed position to a fully open position;
- determining that the tailgate is in the fully open position;
- discontinuing operation of the motor to attempt to lower the tailgate;
- determining that a difference between a number of motor rotation edges expected to occur during operation of the motor to lower the tailgate from the fully closed position to the fully open position, and a number of motor rotation edges that occurred during operation of the motor to attempt to lower the tailgate from the fully closed position to the fully open position, is greater than or equal to a predetermined tolerance value;
- and
- responsive to the determination that the difference is greater than or equal to the predetermined tolerance value, generating an alert indicating a need for manual reset of the tailgate.
A method for controlling a power tailgate in a vehicle power tailgate system, the method comprising steps of:
- controlling operation of a motor to attempt to lower the tailgate from a fully closed position to a fully open position;
- determining that a number (EEO) of motor rotation edges expected to occur during operation of the motor to lower the tailgate from the fully closed position to the fully open position has been reached;
- determining that the tailgate has not reached the fully open position;
- and
- responsive to the determinations that the number (EEO) of motor rotation edges expected to occur during operation of the motor to lower the tailgate from the fully closed position to the fully open position has been reached and the tailgate has not reached the fully open position, generating an alert indicating a need for manual reset of the tailgate.
A method for controlling a power tailgate in a vehicle power tailgate system, the method comprising steps of:
- controlling operation of the motor to attempt to raise the tailgate from a fully open position to a fully closed position;
- determining that a number of motor rotation edges expected to occur during operation of the motor to raise the tailgate from the fully open position to the fully closed position has been reached;
- determining that the tailgate has not reached the fully closed position;
- and
- responsive to determinations that the number of motor rotation edges expected to occur during operation of the motor to raise the tailgate from the fully open position to the fully closed position has been reached and the tailgate has not reached the fully closed position, generating an alert indicating a need for manual reset of the tailgate.
