Embodiment Construction

[0015] The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application or uses.

[0016] generally in figure 1 A diagram of a system with an H-bridge electrical harness providing connections between the engine controller and the digital linear actuator (DLA) is shown at 10. System Shown in FIG. 10 is an H-bridge electrical harness 12 having a first electrical connector 14A and a second electrical connector 14B. A first electrical connector 14A provides a connection to a wiring harness 16 of an engine control unit (ECU) 18, and the ECU 18 receives situational inputs, shown generally at 20, indicative of various conditions of the vehicle , such as but not limited to, driver input 22 , engine speed in RPM 24 , engine manifold absolute pressure (MAP) 26 , engine temperature 28 , air temperature 30 , or other combinations of inputs.

[0017] The wiring harness 12 also includes an application ...

Abstract

An integrated H-bridge electrical harness for controlling an actuator, such as a stepper motor, where the harness includes a signal converter in electrical communication with an ECU, a driver in electrical communication with the signal converter, and a plurality of connectors. At least one of the connectors provides a connection with the ECU, and another of the connectors provides a connection with an actuator. The signal converter receives a first type of signal (such as a pulse width modulated signal) from the ECU, and converts the first type of signal to a second type of signal, and the signal converter sends the second type of signal to the driver. The driver sends a third type of signal (such as a double square wave signal) to the actuator to control the actuator.

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 61 / 666,021, filed June 29, 2012, U.S. Provisional Application No. 61 / 677,241, filed July 30, 2012, and U.S. Nonprovisional Application, filed April 29, 2013 Interest in No. 13 / 872,509. The disclosure of the above application is incorporated herein by reference. technical field [0003] The present invention generally relates to an H-bridge electrical wiring harness for providing a connection between an engine controller and a digital linear actuator, such as a stepper motor. Background technique [0004] Stepper motors such as bipolar stepper motors require a bi-wave signal for proper operation. This bi-wave signal is typically generated from an L / R driver such as an electrical H-bridge driver. For many vehicle platforms, engine control units (ECUs) have limited architecture in available output signals and cannot provide the required drive signals (such as bi-...
