Inching control system

A materials handling vehicle control system comprising:

• one or more memory components storing executable instructions;
• one or more electronic processors in communication with the one or more memory components;
• a traction control device for generating a traction control device input;
• an inching device for generating an inching device input;
• execution of the executable instructions by the one or more electronic processors causes the one or more electronic processors to collectively:
• determine:
• (i) a speed setpoint input value based on the traction control device input, (ii) a speed modification value based on the inching device input and (iii) a target speed setpoint based on the speed modification value and the speed setpoint input value;
• and
• control a traction motor on the vehicle based on the target speed setpoint.
