1. A method for operating a materials handling vehicle comprising:
monitoring, by a processor, vehicle acceleration in a direction of travel of the vehicle during a manual operation by an operator of the vehicle when the vehicle is traveling in a first vehicle orientation;
collecting and storing, by the processor, data related to the monitored vehicle acceleration in the direction of travel of the vehicle comprising data related to the monitored vehicle acceleration when the vehicle is traveling in the first vehicle orientation during the manual operation;
receiving, by the processor, a request to implement a semi-automated driving operation;
calculating, by the processor, a maximum vehicle acceleration based on acceleration data comprising the stored data, wherein the data related to the monitored vehicle acceleration in the direction of travel of the vehicle used in calculating the maximum vehicle acceleration comprises only the vehicle acceleration data in the direction of travel of the vehicle collected when the vehicle is traveling in the first vehicle orientation; and
based at least in part on the maximum vehicle acceleration, controlling, by the processor, implementation of the semi-automated driving operation.
