Vehicular navigation control interface

A vehicle comprising a vehicle control module (VCM), a navigation control module (NCM), a hardware interface, and a steering control system wherein:

• the steering control system comprises a steering control module (SCM) and a steering motor;
• the VCM facilitates operator initiated control of the vehicle in a manual mode;
• the NCM causes the vehicle to implement an automatic control function by travelling to a predetermined destination and performing a desired task using the steering system upon receipt of an automatic command from a navigation system;
• the NCM sends data related to the automatic command for implementing the automatic command;
• the hardware interface connects the VCM and the NCM to facilitate communication of data between the VCM and NCM;
• the VCM sends steering data to the NCM via the navigation control interface for implementing the automatic control function;
• and
• the steering data comprises wheel angle feedback, a counterclockwise wheel angle limit, a clockwise wheel angle limit, a wheel angle rate limit, or a combination thereof.

A vehicle comprising a vehicle control module (VCM), a navigation control module (NCM), a hoist control system, and a hardware interface, wherein:

• the hoist control system comprises a hoist control module and a hoist control motor;
• the NCM causes the vehicle to implement an automatic control function by travelling to a predetermined destination and performing a desired task using the hoist control system upon receipt of an automatic command from a navigation system;
• the NCM sends data related to an automatic command for implementing an automatic control function;
• the hardware interface connects the VCM and the NCM to facilitate communication of data between the VCM and NCM;
• the VCM sends hoist data to the NCM via the navigation control interface for implementing the automatic control function;
• and
• the hoist data comprises a fork height, a hoist speed limit, a hoist acceleration limit, a hoist height limit, or a combination thereof.

A system comprising a navigation system and a vehicle with a vehicle control module (VCM), a navigation control module (NCM), an accessory control system, and a navigation control interface, wherein:

• the vehicle comprises an accessory
• the accessory control system comprises an accessory control module and an accessory control motor;
• the NCM causes the vehicle to implement an automatic control function by travelling to a predetermined destination and performing a desired task using the accessory upon receipt of an automatic command from the navigation system;
• the navigation control interface connects the VCM and the NCM to facilitate communication between the VCM and NCM for implementing the automatic control function and for reporting implementation of a manual mode;
• the VCM sends accessory data to the NCM via the navigation control interface for implementing the automatic control function of an accessory of the vehicle;
• and
• the accessory data comprises a first accessory position, a second accessory position, an accessory upper limit, and an accessory lower limit, or a combination thereof.
