Adaptive acceleration for materials handling vehicle

A system for operating a materials handling vehicle comprising:

• a memory storing executable instructions;
• a processor in communication with the memory, the processor when executing the executable instructions:
• monitors and stores first data regarding a vehicle drive parameter during a previous manual operation of the vehicle by an operator;
• replaces the stored first data, regarding the monitored vehicle drive parameter, associated with the previous manual operation of the vehicle by the operator with second data regarding the monitored vehicle drive parameter monitored and stored during a most recent manual operation of the vehicle, the second data comprises sequential individual values associated with the vehicle drive parameter;
• receives a request to implement a semi-automated driving operation of the vehicle;
• groups the sequential individual values into a plurality of subsets of values, each subset comprising a same predetermined number of adjacent individual values;
• for each of the plurality of subsets, calculates a respective arithmetic or weighted average associated with that subset based at least in part on the individual values in that subset such that an arithmetic average and at least one weighted average are calculated;
• selects a particular one of the arithmetic average and the at least one weighted average;
• and
• controls implementation of the semi-automated driving operation based on the particular one of the arithmetic average and the at least one weighted average.
