1. A method of moving a receiver associated with a hitch frame of a vehicle, comprising:
- receiving data indicating a current range of a transmission of the vehicle;
receiving sensor data indicating a current position of the receiver on the hitch frame;
controlling, by a processor, the receiver to a desired position based on a value of the current range;
wherein when the current range is other than a reverse range, determining, by the processor, the desired position to be a center position relative to a longitudinal axis of the vehicle and based on the current position of the receiver on the hitch frame, outputting one or more control signals to a motor coupled to the receiver to move the receiver relative to the longitudinal axis of the vehicle to the desired position; and
wherein when the current range is the reverse range, determining, by the processor, the desired position based on a speed of the vehicle and a hand wheel angle, and based on a received activation input, retrieving, by the processor, from a look-up table stored in a datastore, the desired position for the receiver on the hitch frame based on the hand wheel angle and the speed of the vehicle, and outputting one or more control signals to the motor coupled to the receiver to move the receiver relative to the longitudinal axis of the vehicle to the desired position.

Abstract
Methods and apparatus are provided for moving a receiver associated with a hitch frame of a vehicle. The method includes receiving data indicating a hand wheel angle; determining, with a processor, a position for the receiver relative to the hitch frame based on the hand wheel angle; and outputting one or more control signals to a motor coupled to the receiver to move the receiver relative to a longitudinal axis of the vehicle based on the determination.

6. A vehicle, comprising:
-
an engine having an engine control module; a movable hitch system including a receiver movably coupled to a hitch frame and a motor having an output shaft coupled to the receiver to move the receiver on the hitch frame; a source of data that provides a hand wheel angle, a vehicle yaw rate, a force acting on the motor associated with the receiver and a vehicle speed; a control module, having a processor, that; determines the vehicle yaw rate is greater than a first threshold; determines whether the hand wheel angle is less than a second threshold; determines whether the force acting on the motor is greater than a third threshold; determines whether the vehicle speed is greater than a fourth threshold; and based on the determination that the vehicle yaw rate is greater than the first threshold, the hand wheel angle is less than the second threshold, the force acting on the motor is greater than the third threshold and the vehicle speed is greater than the fourth threshold, outputs a throttle position for the engine control module to control a speed of the engine and outputs one or more control signals to the motor to move the receiver on the hitch frame. - View Dependent Claims (7, 8, 9, 10, 11)
