Embodiment approach
[0051] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the following description is merely exemplary in nature and is not intended to limit the disclosure, its subject matter, application or uses. To this end, exemplary embodiments of systems and methods for waking up an electronic control unit and protecting the electronic control unit from motor back EMF when a controlled member moves are provided so that this disclosure will be thorough and inform the art Technician adequately communicates range. Numerous specific details are set forth, such as examples of specific components, devices, and methods, to provide a thorough understanding of the embodiments in many different forms and should not be construed as limiting the scope of protection intended to be afforded by the present disclosure. As can be appreciated, some well-known processes, structures and techniques have not been described in detail herein in view of ...
example 1
[0102] Example 1. A system for waking up an electronic control unit when a controlled member moves, comprising:
[0103] a powered drive unit comprising an electric motor coupled to the controlled member and in electrical communication with the electronic control unit for moving the controlled member and passing the motor in response to manual movement of the controlled member The back electromotive force in produces electrical output;
[0104] wherein the electronic control unit is capable of operating in an operating mode or a sleep mode;
[0105] a comparator subsystem coupled to the power drive unit and configured to:
[0106] comparing the electrical output to an electrical reference; and
[0107] Waking the electronic control unit from the sleep mode to the operational mode based on a comparison of the electrical output of the powered drive unit to the electrical reference.
example 2
[0108] Example 2. The system for waking up an electronic control unit upon movement of a controlled member of example 1 , wherein the comparator subsystem is further configured to compare the electrical output of the powered drive unit with the comparison with an electrical reference to dissipate the back EMF.
