  • Patent number: 9785610
    Abstract: A vehicle wheel service system configured to present an operator with an interactive visual display of vehicle service system components and a virtual model of the actual wheel assembly undergoing service. The interactive visual display includes representations of various parameters associated with the wheel assembly and vehicle service system and enables virtual manipulation of the positional relationship of components such as imbalance correction weights and the tire relative to the vehicle wheel rim, providing a visual representation of the resulting effects on the parameters of the vehicle wheel assembly, and enables viewing of various real-time operations from a safe location away from moving components, as well as visualization of operations prior to implementation.

  • Patent number: 9702780
    Abstract: A vehicle wheel balancer system having a processing system and a spindle shaft upon which a vehicle wheel assembly is mounted for measurement of imbalance characteristics and forces. The processing system is configured with software instructions to evaluate the remaining imbalance present in a vehicle wheel assembly following the application of imbalance correction weights, and to determine if the remaining imbalance is the result of the vehicle wheel assembly having deviated from an expected rotational position during the time between the measurement of the imbalance and the application of the imbalance correction weights. In the event of such a deviation, the processing system is further configured to provide the operator with a suitable warning to evaluate and correct the mounting of the vehicle wheel assembly before proceeding to rebalance or re-measure the vehicle wheel assembly.

  • Publication number: 20150178663
    Abstract: A method for providing performance tracking, operator guidance, and feedback by monitoring operator interactions with a vehicle service system. The operator's interactions with the service equipment during a vehicle service procedure which produce detectable effects are monitored. If an operator completes a vehicle service procedure correctly, a visual or audible announcement is provided, and an entry recorded in a system log. If an operator mistake is detected during the vehicle service procedure, a different visual or audible announcement is provided, and a suitable entry recorded in the system log. The system log is subsequently utilized to generate a performance score, either based on overall system usage, or upon the usage by a specific operator if operator-identifying information is available during each service procedure.

  • Patent number: 8813543
    Abstract: A method for reducing imbalance correction weight usage during a balancing operation of a vehicle wheel assembly. An imbalance of the vehicle wheel assembly is initially determined and utilized together with an established acceptable threshold of imbalance for the vehicle wheel assembly to compute a reduced imbalance value having a magnitude less than the determined imbalance. Using the reduced imbalance value, correction weight amounts and placement locations for application to the vehicle wheel assembly are identified. Determined differences between the identified correction weight amount using the reduced imbalance value and a convention correction weight amount are identified as imbalance correction weight savings.

  • Publication number: 20140000363
    Abstract: A method by which a vehicle wheel service system, having at least one load roller for applying a generally radial load to a wheel assembly mounted on a driven spindle shaft during rotation thereof, provides a measurement which is representative of the loaded rolling resistance of the wheel assembly undergoing testing. In order to rotationally drive the spindle shaft with the vehicle wheel assembly mounted there on, energy is supplied to a drive motor operatively coupled to rotationally drive the spindle shaft. By monitoring the amount of energy or drive torque required to rotationally drive the spindle shaft and achieve and maintain a desired rotational speed for the wheel assembly when engaged with the load roller, a measurement which is related to the loaded rolling resistance of the wheel assembly is obtained by the vehicle wheel balancing system.

  • Patent number: 8453335
    Abstract: A vehicle wheel assembly service system configured to acquire measurements of the physical characteristics of a vehicle wheel assembly such as during a vehicle wheel balancing procedure, with the functionality to obtain and utilize a measurement of a vehicle wheel assembly offset or rear spacing. The vehicle wheel assembly service system is configured to display the wheel assembly offset or rear spacing measurement to an operator, and optionally, to display guidance and/or installation instructions to the operator associated with the installation of the vehicle wheel assembly on a vehicle. The displayed guidance and/or installation instructions may optionally include fitment information, vehicle performance data, or vehicle braking data.

  • Patent number: 7617726
    Abstract: A method of operation of a vehicle wheel balancer system for identifying an imbalance correction weight mode which an operator desires to utilize during an imbalance correction procedure without requiring the operator to manually input or select an imbalance correction weight mode prior to beginning the placement of the imbalance correction weights. The imbalance correction weight mode is determined from operator guided movements of one or more dataset arms which identify if an operator-selected imbalance correction weight placement plane is associated with a clip-on imbalance correction weight, an adhesive imbalance correction weight, or a patch-type imbalance correction weight.
