Abstract
A display module and method are disclosed to show the positional relationship of both the direction and distance of a vehicle relative to a desired approach course leading to a loading point.
Claims20
A display module for a vehicle comprising:
- a course deviation indicator that is configured to provide an indication of a first angle between a desired approach course 213 and a first line, wherein the first line extends between a first point on the vehicle and a virtual origin point;
- a heading indicator that is configured to provide an indication of a second angle between a vehicle forward alignment and the desired approach course, wherein the vehicle forward alignment is a longitudinal centerline of the vehicle that extends through the first point on the vehicle;
- a lateral deviation indicator that is configured to provide an indication of a distance from the first point on the vehicle to a loading line, wherein the loading line extends through a loading point;
- wherein the loading point is located on the desired approach course and the desired approach course is a desired course for the vehicle to approach the loading point.

A method of indicating a position of a vehicle using a display, wherein the display comprises a course deviation indicator, a heading indicator, and a lateral deviation indicator, the method comprising:
- establishing a desired approach course that extends through a loading point and a virtual origin point;
- determining a first angle that is between the desired approach course and a first line, wherein the first line extends between a first point on the vehicle and the virtual origin point;
- determining a second angle that is between a vehicle forward alignment and the desired approach course, wherein the vehicle forward alignment is a longitudinal centerline of the vehicle that extends through the first point on the vehicle;
- determining a distance from the first point on the vehicle to a loading line, wherein the loading line extends through the loading point;
- providing an indication of the first angle with the course deviation indicator;
- providing an indication of the second angle with the heading indicator;
- providing an indication of the distance from the first point on the vehicle to the loading line with the lateral deviation indicator.

A method of positioning a receiving point on a vehicle at a loading point, the method comprising:
- establishing a desired approach course that extends through the loading point and a virtual origin point;
- determining a first angle that is between the desired approach course and a first line, wherein the first line extends between the receiving point on the vehicle and the virtual origin point;
- determining a second angle that is between a vehicle forward alignment and the desired approach course, wherein the vehicle forward alignment is a longitudinal centerline of the vehicle that extends through the receiving point on the vehicle;
- determining a distance from the receiving point on the vehicle to a loading line, wherein the loading line extends through the loading point;
- moving the vehicle toward the loading point;
- adjusting the motion of the vehicle and vehicle forward alignment relative to the desired approach course based on the first angle and second angle such that the vehicle moves toward the desired approach course;
- moving the vehicle along the desired approach course;
- adjusting the motion of the vehicle along the desired approach course based on the distance from the receiving point on the vehicle to a loading line;
- stopping the vehicle when the receiving point reaches the loading point.
