  • Patent number: 10377388
    Abstract: A traction application executing on a vehicle control module receives a traction speed control input to control a traction wheel of the vehicle. Based on the traction speed control input, the traction application determines a first setpoint value of a control attribute related to the traction wheel. A first diagnostic supervisor receives a measured value of the control attribute related to the traction wheel, and the first setpoint value from the traction application. The first diagnostic supervisor comprises a first model of a traction system of the vehicle. Based on the first setpoint value and the first model, the first diagnostic supervisor calculates a first virtual value of the control attribute related to the traction wheel. Based on the first virtual value and the measured value of the control attribute, the first diagnostic supervisor determines a first operating condition of the traction system of the vehicle.

  • Patent number: 10380473
    Abstract: Electronic badges are indirectly tracked by detecting, by a badge communicator on a select industrial vehicle of a fleet of industrial vehicles, the presence of an electronic badge and performing a badge logging transaction in response to detecting the electronic badge. The badge logging transaction includes receiving, by the badge communicator, a badge identifier transmitted by the detected electronic badge. The badge logging transaction also includes determining, by the badge communicator, an offset measurement of the electronic badge relative to the select industrial vehicle, electronically determining a vehicle location of the select industrial vehicle, and identifying a badge location based upon the determined vehicle location and the measured offset. The badge logging transaction can also include generating a time stamp, and wirelessly communicating a badge locator message to a remote server, the badge locator message including the badge identifier, the badge location, and the timestamp.

  • Patent number: 10301155
    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.

  • Patent number: 10255769
    Abstract: A process uses electronic badges to convey a condition associated with an environment to an industrial vehicle. The process comprises identifying a condition in a limited, defined environment and associating the identified condition with a badge ID. The process also comprises programming an electronic badge based upon the identified condition and positioning the electronic badge within a work area of industrial vehicles. Still further, the process comprises receiving, by a processor on an industrial vehicle, information from the electronic badge including at least one of the associated badge ID and the identified condition. The information is received via a badge communicator that communicates with electronic badges that are within a predetermined range of the industrial vehicle via a first wireless communication link. The process also determines the condition from the information from the electronic badge, and controls the industrial vehicle to take a predetermined action based upon the determined condition.

  • Patent number: 10257646
    Abstract: An industrial vehicle passing maneuver is authorized by an automated process. The process comprises receiving, by a processor, a first message, a second message and a third message. The first message indicates a position of a first industrial vehicle in a work environment. The second message indicates a position of an electronic badge that is detected by the first industrial vehicle. The third message indicates a position of a second industrial vehicle within the work environment. The processor determines that the second industrial vehicle intends to pass the first industrial vehicle, and determines an instruction comprising a select one of an instruction related to a passing maneuver or an instruction not to pass based upon the position of the first industrial vehicle, the position of the electronic badge, and the position of the second industrial vehicle. The instruction is communicated to the second industrial vehicle.
