Abstract

Automotive service equipment and method of servicing an automotive vehicle use an automotive service machine having at least one automatic mode of operation during which an operator is not required to be present. A first, stationary communication module connected to the service machine receives first signals from the machine indicating the status of an automatic mode of operation of the machine and wirelessly transmits second signals communicating when an operator'"'"'s attention to the machine is required. A second, portable communication module remotely receives the second signals and in response activates a signaling device in the second module for signaling an operator that attention to the machine is required. Thereby, during vehicle servicing the operator can perform other tasks within the workshop, thus being more productive and efficient.

Claims

1. Automotive service equipment comprising:

an automotive service machine having at least one automatic mode of operation for servicing a vehicle during which an operator is not required to be present;

a first, stationary communication module connected to the automotive service machine, the machine generating and sending to the first communication module first signals indicating the status of an automatic mode of operation of the machine and the first communication module interpreting said first signals and wirelessly transmitting second signals communicating when an operator'"'"'s attention to the machine is required;

a second, portable communication module which remotely receives the second signals and in response activates a signaling device in the second communication module for signaling an operator that attention to the machine is required.

2. The automotive service equipment according to claim 1, wherein the second signals are wirelessly transmitted by the first communication module when at least one of a process input is required, a process is halted due to an operation fault condition, and a process is completed.

3. The automotive service equipment according to claim 1, wherein the automotive service machine includes a controller for operating the machine in at least one automatic mode of operation and for sending the first signals from the machine to the first communication module, and wherein the first communication module is embedded within the controller.

4. The automatic service equipment according to claim 1, wherein the automotive service machine includes a controller for operating the machine in the at least one automatic mode of operation and for sending the first signals from the machine to the first communication module, and wherein the first communication module is installed in the machine as a separate modular unit via a cable with plug connector at a communication port of the controller.

5. The automotive service equipment according to claim 1, further comprising a workshop management computer system, the first communication module wirelessly transmitting signals to and receiving wirelessly transmitted signals from the workshop management computer system.

6. The automotive service equipment according to claim 5, wherein signals are wirelessly transmitted by the first communication module to the workshop management computer system when at least one of a process is started, a process is halted, and a process is completed.

7. The automotive service equipment according to claim 6, wherein signals are wirelessly transmitted from the workshop management computer system to the first communication module to indicate at least one of initiate service and work order number.

8. The automotive service equipment according to claim 1, wherein the second, portable communication module is a pocket-sized module for carrying by an operator.

9. The automotive service equipment according to claim 1, including a plurality of automotive service machines each having at least one automatic mode of operation for servicing a vehicle during which an operator is not required to be present, and a plurality of first communication modules each connected to a respective one of the automotive service machines for receiving first signals from the machine indicating the status of an automatic mode of operation of the machine and wirelessly transmitting second signals when an operator'"'"'s attention to the machine is required, and wherein the second, portable communication module receives the second signals from each of the first communication modules and in response activates a signaling device in the second communication module for signaling an operator that attention to the machine is required.

10. The automotive service equipment according to claim 9, wherein the plurality of automotive service machines include different types of automotive service fluid handling machines selected from the group consisting of machines for:

power steering fluid exchange,

differential fluid exchange,

engine oil system flush,

engine coolant exchange,

air conditioner refrigerant charging/recovery/recycling,

air conditioner flush,

transmission fluid handling,

brake fluid exchange, and

nitrogen tire filling.

11. The automotive service equipment according to claim 1, including means permitting the operator to selectively activate the first communication module at the machine.

12. The automotive service equipment according to claim 1, wherein the signaling device in the second, portable communication module includes at least one of an indicator light, an audible buzzer and a vibrator for signaling an operator.

13. The automotive service equipment according to claim 1, wherein one of the first communication module and the second, portable communication module wirelessly transmits third signals to the other for indicating that the second, portable communication module is out of range.

14. A method of servicing an automotive vehicle using an automotive service machine having at least one automatic mode of operation during which an operator is not required to be present, the method comprising:

initiating an automatic mode of operation of the automatic service machine for servicing a vehicle;

indicating by first signals from the machine to a first, stationary communication module connected to the machine, the status of the automatic mode of operation of the machine;

interpreting the first signals from the machine to the first communication module and wirelessly transmitting second signals from the first communication module when an operator'"'"'s attention to the machine is required;

remotely receiving the second signals at a second, portable communication module;

signaling by a signaling device in the second communication module that an operator'"'"'s attention to the machine is required in response to the receipt of the second signals by the second communication module.

15. The method according to claim 14, further comprising the first communication module wirelessly communicating with a workshop management computer system.

16. The method according to claim 14, wherein the signaling that an operator'"'"'s attention to the machine is required takes place when at least one of a process input is required, a process is halted due to an operation fault condition, and a process is completed.

17. The method according to claim 14, including the second, portable communication module receiving wirelessly transmitted signals from each of a plurality of first communication modules connected to respective ones of a plurality automotive service machines each having at least one automatic mode of operation.

18. The method according to claim 17, wherein the plurality of automotive service machines include different types of automotive service fluid handling machines selected from the group consisting of machines for:

power steering fluid exchange,

differential fluid exchange,

engine oil system flush,

engine coolant exchange,

air conditioner refrigerant charging/recovery/recycling,

air conditioner flush,

transmission fluid handling,

brake fluid exchange, and

nitrogen tire filling.

19. The method according to claim 14, including selectively activating the first communication module at the machine for performing the method.

20. The method according to claim 14, wherein the signaling device includes at least one of an indicator light, an audible buzzer and a vibrator.

21. The method according to claim 14, including wirelessly transmitting signals from one of the first communication module and the second portable communication module to the other of said first communication module and said second portable communication module for indicating that the second, portable communication module is out of range.
