Sensor configuration for a materials handling vehicle
First Claim
1. A materials handling vehicle comprising:
- a power unit;
a load handling assembly coupled to said power unit;
at least one obstacle detector mounted to said power unit to detect an object located along a path of travel of said power unit, said detector generating a distance signal upon detecting an object corresponding to a distance between the detected object and said power unit;
a controller receiving said distance signal and generating a corresponding vehicle stop or predetermined maximum allowable speed signal based on said distance signal, wherein if a sensed object is located within a speed zone associated with a predetermined maximum allowable travel speed comprising a fixed speed greater than zero (0) miles per hour, as determined by said distance signal, the vehicle speed is reduced to the predetermined maximum allowable vehicle speed; and
a presence sensor that detects the presence of an operator in an operator'"'"'s station of the materials handling vehicle, wherein said controller is responsive to remote travel requests and determines whether to implement each remote travel request based on the evaluation of at least one vehicle condition, said at least one vehicle condition evaluated by said controller comprising a status of said presence sensor, wherein said controller is configured to decide to not implement said remote travel request if said status from said presence sensor is indicative of the presence of an operator in the operator'"'"'s station of the materials handling vehicle.

Abstract
A materials handling vehicle includes a power unit; a load handling assembly coupled to the power unit; at least one obstacle detector mounted to the power unit; and a controller. The at least one obstacle detector detects object located along a path of travel of the power unit, and generate a distance signal upon detecting an object corresponding to a distance between the detected object and the power unit. The controller receives the distance signal and generates a corresponding vehicle stop or predetermined maximum allowable speed signal based on the distance signal, wherein if a sensed object is located within a speed zone associated with a predetermined maximum allowable travel speed comprising a fixed speed greater than zero (0) miles per hour, as determined by the distance signal, the vehicle speed is reduced to the predetermined maximum allowable vehicle speed.
