摘要:
An integrated electronic starting control system module for diesel engines which provides unique packaging with integration of a multiplicity of features previously unavailable or available only in separate control modules. Integrated into one modular device are improved glow plug and starting system control, monitoring, protection, and diagnostic features. These features for rendering improved glow plug control and diagnostics include: Microprocessor control, adaptive control algorithms, engine analog temperature sensing for glow plug operational compensation, over temperature shut down protection, system glow plug voltage sensing for glow plug operational compensation, timers for control of glow plug operation and duty cycles, sensing of glow plug current for protective shutdown, control relays and/or solid state switches for control of glow plug current(s), manual override control, load dump voltage spike avoidance circuitry based upon alternator output speed, system monitoring with diagnostics communication capability.

An electronic control system and a device is disclosed proving improved control and diagnostics of glow plugs as are typically energized in diesel engines prior to and during cold start and also during engine warmup, especially for motor vehicles under human operator control. These improved control functions result in: Increased life of the glow plugs, longer service life, greater reliability, a simplified maintainence diagnostic interface, greater diagnostic capability, reduced emission of undesirable hydrocarbons, reduced unburned fuel as white smoke, more complete fuel combusion, reduced lubricating oil contamination, quiter and smoother operation, increased engine power, reduced fuel consumption, and quicker engine warmup all by controlling power applied to the glow plugs based upon electronically controlled fixed and/or adaptive functional algorithms based upon input variables such as battery voltage, glow plug voltages, glow plug currents, engine temperature based upon algorithms which can correct for sensing system hysteresis and time lag, ambient air termperature ambient air density, ambient air humidity, fuel injector duration and timing, intake mass air flow, exhaust gas composition, exhaust gas temperature, alternator output, engine speed, engine torque, engine power, engine compression, engine age, fuel type, and the like for affecting an on and off cycling using open loop control and/or closed loop feedback control of glow plug power so as to maintine glow plugs more closely within an optimal temperature range specific to engine system operational conditions and consistent with improved glow plug life.

A vehicle trailer connect system and automated parking system for use with a motor vehicle. Apparatus of the system has an input for obtaining information from a vehicle communication bus; an output for sending information to a vehicle communications bus; a control circuit for controlling the position and movement of a motor vehicle; an image gathering system to obtain visual or spatial data between a motor vehicle hitch and a hitch receiver attached to the trailer. A system controller guides vehicle steering as the vehicle is backed through a field of view of the image gathering system.

A system or method for tracking items proximate a user interface device include a user interface device having at least one solid-state touch-sensitive region and a receiver for wirelessly receiving a signal from at least one item to determine proximity of the item relative to the user interface device. The device may also include a display screen for displaying controls and information. The user interface device may be permanently or removably mounted in a vehicle and used to interface with vehicle systems and personal electronic devices for control and information display. Tracked items or objects may include passive or active data tags and communicate identification information and optionally position information to the user interface device. The device may alert the user to movement of tracked objects, and/or confirm presence of a group of objects intended for a particular task or project.

A keyless entry assembly for a vehicle includes a sensor carrier, a sensor in the form of an electrically conductive pad, and a controller. The sensor is mounted to the sensor carrier and the sensor carrier is positioned adjacent a panel such that the sensor is adjacent the panel. The sensor capacitively couples to an electrically conductive object proximal to the panel while the sensor is driven with electrical charge such that capacitance of the sensor changes due to the sensor capacitively coupling with the object. The controller is operable for driving the sensor with the electrical charge and controlling a vehicle operation as a function of the capacitance of the sensor.

摘要:
An anti-entrapment system for preventing an object from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device. The sensor has first and second flexible conductors separated by a separation distance. The conductors have a capacitance dependent on the separation distance. The sensor has a compressible dielectric element interposed between the conductors. The capacitance of the conductors changes in response to the separation distance changing as a result of the dielectric element compressing in response to a first object touching the sensor. The capacitance of the conductors changes in response to a second conductive object coming into proximity with at least one conductors. A controller controls the translating device as a function of the capacitance of the conductors to prevent the translating device from entrapping either of the first object or the second conductive object.
摘要:
A position sensing device including two spaced conductive coils constituting a primary and secondary winding of a transformer. A coupling member is mounted to a moveable object. This movement adjusts or alters the transformer coupling between the primary and the secondary and produces a variable output signal which can be correlated to the position of the moveable member. An electronic module is coupled to a programmable controller and adjusts an output from the linear position sensor to linearize the output with relative movement of first and second members such as components of a vehicle shock absorber.
摘要:
Apparatus for providing a heated cleaning fluid to a vehicle surface having an inlet port for receiving an amount of fluid; a housing bounding a reservoir in fluid communication with the inlet port; and an outlet port in fluid communication with the reservoir for dispensing an amount of heated fluid. A heater element heats fluid that passes from the inlet to the outlet port through the reservoir. A heat exchanger in thermal contact with the heater element for conveying heat to the fluid within the reservoir has a strut that divides fluid entering the housing through the inlet port into two flow paths and elongated fins that extend outwardly from the strut at transverse angles that bound fluid flow channels for fluid moving through said reservoir. A control circuit energizes the heater element with a voltage to heat the heating element and the fluid passing from the inlet to the outlet through the reservoir.

An anti-entrapment system for preventing an object from being entrapped by a translating device includes a capacitance sensor positioned adjacent to the translating device. The sensor has first and second conductors separated by a separation distance, a compressible dielectric element interposed between the conductors, and a non-conductive elastomer outer jacket encasing the conductors and the dielectric element. The sensor having a capacitance dependent upon the separation distance between the conductors. The capacitance changes in response to the separation distance changing as a result of the dielectric element compressing in response to a first object touching the outer jacket, and in response to a second conductive object coming into proximity with at least one of the conductors. A controller controls the translating device as a function of the capacitance in order to prevent the translating device from entrapping either object.
