Abstract
The trailer backup assist system has a human machine interface coupled to a controller having a setup module, a calibration module, an activation module and a control module configured to receive trailer measurements, apply trailer measurements, activate and control vehicle systems to calibrate and implement a curvature control algorithm that controls the reverse movement of the vehicle-trailer combination in a manner consistent with a driver request. When incorrect trailer measurements have been entered, the trailer backup assist system recognizes the error, initiates a warning and requests corrective action to correct the trailer measurements. Default values for a maximum controllable curvature limit and a maximum controllable angle replace the limits calculated and applied by the calibration model that used incorrect trailer measurements, until corrected trailer measurements may be entered by the driver.
