摘要： A materials handling vehicle, such as a turret stockpicker, is provided with control circuits and hardware to allow an operator to control the vehicle from either a standing or seated position while providing all of the safety interlocks that ensure proper operation of the vehicle. All functions of the vehicle, including raising and lowering of forks and moving the vehicle, are affected by the operator's position. The switch associated with the operator's seat indicates whether the operator is in the standing or seated position, and the control of the vehicle is appropriately modified to conform to industry standards according to the mode selected from the operator. An electronic circuit is responsive to an operator actuated seat switch to control the mode of operation wherein, a) if the operator is standing, floor operated switches control the braking of the vehicle, with braking being applied upon release of either of said switches, and b) if the operator is sitting, a pair of pedestal switches must both be activated to permit selected operations of the vehicle and lift truck functions, and wherein braking is controlled by the operation of a pedestal brake switch.

摘要： A speed control circuit is provided for a lift truck which is driven by an electric truck drive motor powered from a power source through a motor controller. The motor controller is responsive to a power control signal generated by summing a speed sensor signal, which is derived by comparing a tachometer signal with a speed selection signal. A fork height sensor provides a fork height signal which is used to limit the maximum level of the speed control signal. A safety circuit monitors operation of the speed control circuit and disconnects the circuit from the motor controller upon occurrence of a malfunction.

摘要： A personnel carrying vehicle comprises a self propelled, steerable body, a telescoping mast attached to and extending upwardly from the body, and a personnel compartment attached to the mast. Two control handles are mounted within the personnel compartment, with one handle including a rocker mechanism mounted therein for pivotal movement within a generally horizontal plane to control steering and the other handle being rotated to controlling traction. Sensors ensure that the operator's hands are on both control handles and both feet are properly positioned on a floor of the operator's compartment before the vehicle can be moved or the platform raised; this ensures a four point stance, providing for operator stability and that the operator's hands and feet are within the operator's compartment anytime the vehicle is being moved or during lifting or lowering operations.

摘要： A fork lift truck includes a fork level sensor located in the forks, away from the vertical mast of a lift truck for detecting the true level of the forks, and a vision system including a camera which may take several forms. In one form, a single camera is mounted in a housing which may be moved to a protected location vertically either by sliding in the carriage assembly, or by use of a parallelogram device. In another form, multiple cameras are employed where a second camera may be either mounted above the first camera in the same housing or mounted between the forks. Alternatively, the first camera may perform multiple roles by being moved vertically from a first predetermined location below the bottom of the forks to a higher elevation a second predetermined location relative to the forks. A video display terminal, which shows the view observed by the camera, may also include a fork level indicator, a reticle for assisting in adjusting the vertical position of the forks, and an indicator showing the specific truck function selected by the operator.

摘要： A dynamic clipper is used in the guidance control circuits of a wire guided vehicle, such as a lift truck, that is guided by a wire laid in floors between storage racks into which an alternating electrical signal is provided to remove the effects of noise pulses. The wire signal is detected by sensor coils carried by the vehicle, and the amplitude of this signal is used as an indication of the distance of the vehicle to the wire. The dynamic clipper includes a first comparator having one input from the sensor coil and the other input from a reference source. All noise signals greater than the reference voltage are removed. The output is then passed to an inverter and then to a second comparator which performs the same function. Thus both the positive and negative going noise pulses greater than the reference are removed from the sensor output signal. The resulting output is then rectified with a full wave rectifier and integrated to provide a direct current reference signal, the magnitude of which is therefore related directly to the proximity of the sensor coil to the buried wire.

摘要： An output distance signal related to the distance between an ultrasonic transmitting transducer and an ultrasonic receiving transducer is provided by an apparatus including a reference oscillator and a burst generator responsive to the reference oscillator which periodically generates ultrasonic burst signals. The ultrasonic transmitting transducer is responsive to the generator for providing an ultrasonic acoustic energy burst in response to each of the ultrasonic burst signals. An ultrasonic receiving transducer receives the ultrasonic acoustic energy bursts and generates detection signals in response thereto. A range window circuit is responsive to detection of an acoustic energy burst by the receiving transducer, for providing a range window signal at a time period lagging the detection signal such that a range gate will be opened for passage of the next following detection signal. A converter is responsive to the range gate and to the burst signals for providing an output distance signal, related in potential to the distance between the transmitting and receiving transducers.

摘要： A steering tiller and a steered wheel(s) of a steer-by-wire steering system of a materials handling vehicle are synchronized with one another and a virtual coupling force is exerted on the steering tiller to maintain synchronization. A motor or brake is associated with the steering tiller and the positions of the tiller and the steered wheel(s) are monitored and used to control the motor or brake to apply the virtual coupling force to the tiller. Thus, an operator of the vehicle receives feedback corresponding approximately to that experienced in a mechanically coupled steering system so that synchronism is maintained between the tiller and the steered wheel(s). In this way, if the operator attempts to oversteer or outrun the steered wheel(s) by rapid rotation of the tiller, a force proportional to the operator's action is applied to oppose that action. Synchronization can be set up with the tiller set to a desired position selected by the operator, for example to selected a desired tiller spinner straight ahead position.

摘要： A lift truck control system which utilizes a distributed control network including at least a display module, a distribution module, a traction module, a brake module and a steering module. The display and steering modules each are configurable by software which controls the module and the various drivers in each module. In the preferred embodiment, the display module includes flash memory which stores application software and can be rewritten so that the performance characteristics of the modules are software configurable. The display module is connectable to a programmable cartridge which includes nonvolatile flash memory that carries application software for the display and steering modules. When connected, the cartridge downloads the particular application software which is written over the stored software in flash memory for the display and steering modules. The programmable cartridge also can be used to store and download boot software to the display and steering modules, so that the boot procedure performed by the display and steering modules is also software configurable. The system accepts modules which can be installed in a variety of different lift truck vehicles with minimal physical changes; the performance of the modules is configured by the application software written into the flash memory of the module.

摘要： A materials handling vehicle employs a two step braking process where full brakes are applied to stop the vehicle quickly when it is traveling at a fast rate, and partial braking force is applied to stop the vehicle smoothly when it is traveling slowly. The amount of the braking force is controlled by the spring force applied to the braking shoes. Whenever the vehicle is moving at or less than a predetermined speed, only the brakes on one pair of wheels, typically the load wheel brakes, that is the brakes on the wheels under the load, will be used when braking action is requested. This will permit the vehicle to stop smoothly, and not abruptly as would be the case if full braking were to be applied. If the vehicle is moving faster than the predetermined speed, then full braking force will be applied by actuating the brakes on both pairs of wheels whenever requested by the operator or by the vehicle control system. Both the load wheel brakes and the steered wheel brakes are conventional spring applied brakes which are released by hydraulic pressure applied to individual brake cylinders.
