Abstract

A hydrostatic system includes a hydraulic system and at least one sensor configured to monitor a parameter of the hydraulic system, the at least one sensor including a wireless transmitter configured to generate wireless transmissions based on the parameter. The hydrostatic system further includes an electronic control box including a wireless receiver that is configured to receive the wireless transmissions generated by the at least one sensor. The electronic control box is configured to control the hydraulic system based at least in part on the received wireless transmissions.

First claim

What is claimed is:

1. A hydrostatic system comprising:
a hydrostatic unit;
at least one sensor configured to monitor a parameter of the hydrostatic unit, the at least one sensor including a wireless transmitter configured to generate wireless transmissions based on the parameter; and
an electronic control box including a wireless receiver configured to receive the wireless transmissions generated by the at least one sensor and a processor configured to control the hydrostatic system based at least in part on the received wireless transmissions;
wherein the electronic control box further comprises a wireless transmitter configured to generate reverse wireless transmissions; and
wherein the at least one sensor further comprises a wireless receiver configured to receive the reverse wireless transmissions generated by the electronic control box.

2. The hydrostatic system according to claim 1 , further comprising a housing containing the hydrostatic unit;
wherein the at least one sensor is mounted to the housing.

3. The hydrostatic system according to claim 2 , wherein the electronic control box is mounted to the housing.

4. The hydrostatic system according to claim 2 , wherein the electronic control box is detached from the housing.

5. The hydrostatic system according to claim 1 , wherein the at least one sensor includes a pressure sensor.

6. The hydrostatic system according to claim 1 , wherein the at least one sensor includes a speed sensor.

7. The hydrostatic system according to claim 6 , further comprising at least one second sensor;
wherein the at least one second sensor includes a pressure sensor.

8. The hydrostatic system according to claim 1 , wherein the hydrostatic unit includes a pump.

9. The hydrostatic system according to claim 1 , wherein the hydrostatic unit includes a motor.

10. The hydrostatic system according to claim 1 , wherein the at least one sensor further comprises a battery.

11. The hydrostatic system according to claim 10 , wherein the reverse wireless transmissions include power to charge the battery.

12. A hydrostatic system comprising:
a housing;
a hydraulic system including a pump disposed at least partially within the housing;
at least one sensor mounted through the housing and configured to monitor a parameter of the hydraulic system, the at least one sensor including a wireless transmitter configured to generate wireless transmissions based on the parameter; and
an electronic control box including a wireless receiver configured to receive the wireless transmissions generated by the at least one sensor and a processor configured to control the hydraulic system based at least in part on the received wireless transmissions;
wherein the electronic control box further comprises a wireless transmitter configured to generate reverse wireless transmissions; and
wherein the at least one sensor further comprises a wireless receiver configured to receive the reverse wireless transmissions generated by the electronic control box.

13. The hydrostatic system according to claim 12 , wherein the electronic control box is mounted to the housing.

14. The hydrostatic system according to claim 12 , wherein the electronic control box is detached from the housing.

15. The hydrostatic system according to claim 12 , wherein the at least one sensor further comprises a battery; and
wherein the reverse wireless transmissions include power to charge the battery.

16. A hydrostatic system comprising:
a housing;
a hydraulic system disposed at least partially within the housing;
a plurality of sensors mounted through the housing, each sensor of the plurality of sensors configured to monitor a parameter of the hydraulic system, the plurality of sensors including at least one sensor comprising a wireless transmitter configured to generate wireless transmissions based on the monitored parameter; and
an electronic control box including a wireless receiver configured to receive the wireless transmissions generated by the at least one sensor and a processor configured to control the hydraulic system based at least in part on the received wireless transmissions;
wherein the electronic control box further comprises a wireless transmitter configured to generate reverse wireless transmissions; and
wherein the at least one sensor further comprises a wireless receiver configured to receive the reverse wireless transmissions generated by the electronic control box.

17. The hydrostatic system according to claim 16 , wherein the electronic control box is mounted to the housing.
