Method for operating a control unit of a motor vehicle
A method for operating a control unit of a motor vehicle including a function unit and a monitoring unit which have a communication connection to one another. In a first check, the function unit is checked for errors, an error of the function unit being inferred if an error counter reaches a threshold value, and the monitoring unit and the function unit exchange first data with one another. In the event of a correct exchange of the first data, a positive change of the error counter is carried out. Otherwise, a negative change of the error counter is carried out. In a second check, the monitoring unit and the function unit exchange second data with one another. In the event of an incorrect exchange of the second data, a negative change of the error counter and a negative change of the threshold value are carried out.
Fuel control systems for operating gasoline engines based on ethanol-water-hydrogen mixture fuels
Techniques, systems, and devices are disclosed for converting an alcohol and water mixture to hydrogen-rich gas inside a gasoline engine to power the gasoline engine vehicle. In one aspect of the disclosed technology, an electronic control module installed on a gasoline engine vehicle for controlling the gasoline engine vehicle to run on an alcohol and water mixture as fuel is disclosure. This electronic control module includes a processor, a memory, and an interface coupled to the ECU of the gasoline engine vehicle to receive various sensor signals from the ECU. The electronic control module also includes interconnects coupled to various modules of the gasoline engine vehicle to control a process of running the vehicle on the alcohol and water mixture stored in the gasoline tank of the vehicle. The said process includes converting catalyzed alcohol and water mixture to a hydrogen-rich gas inside a cylinder of the gasoline engine.

Fuel injector calibration method and apparatus
A method for matching the performance of a plurality of electronic fuel injectors, includes: applying a supply voltage to a control module; applying an operating voltage signal having a pulse width to each of the plurality of electronic fuel injectors individually via the control module; measuring an amount of time that each of the plurality of electronic fuel injectors supplies fuel; individually adjusting an operating voltage supplied to each of the plurality of electronic fuel injectors to cause each of the electronic fuel injectors to deliver fuel for a substantially same amount of time.
Engine air path cooling system
Methods and systems are provided for selectively re-cooling intake air downstream of a charge air cooler. In one example, a system may include a cylinder head defining a plurality of cylinders, the cylinder head including a plurality of inlet ports each fluidically coupled to a respective cylinder, a refrigerant supply, and a refrigerant passage surrounding each inlet port and fluidically coupled to the refrigerant supply, the refrigerant passage shaped to correspond to an outer profile of each inlet port.

METHOD AND SYSTEM FOR NVH CONTROL
Methods and systems are provided for reducing driver dissatisfaction from NVH associated with cylinder deactivation. Audio and video feed is captured from inside a vehicle and analyzed to infer if a vehicle operator is distracted. If yes, then a VDE transition is scheduled to occur during the time when the driver is distracted and unlikely to notice the NVH.
