  • Patent number: 10545659
    Abstract: A number of objects simultaneously touching a touch-sensitive operator control unit of an operator control apparatus are detected and a trigger position at which one of the number of objects detected touches the touch-sensitive operator control unit is determined. When more than one object touches the touch-sensitive operator control unit, a touch pressure with which the touch-sensitive operator control unit is acted on overall by the number of objects detected is compared to a predefined pressure threshold value. A function of the motor vehicle, assigned to the trigger position, is triggered if the touch pressure is higher than the predefined pressure threshold value. The predefined pressure threshold value is defined in a manner dependent on the number of objects detected.

  • Patent number: 10412872
    Abstract: Soil working tool for an agricultural machine, in particular a cultivator, which is fixed on a tool holder and has a tine-like region to which a preferably guide plate-like element is attached. In order to achieve an improved soil flow across the soil working tool with good wear protection and thus a sufficient service life of the soil working tool, the tine-like region has two side strips which run in the longitudinal direction of the soil working tool and have notch-like recesses extending in the transverse direction, and that an at least approximately smooth center strip region is located between the two side strips in the center in the longitudinal direction of the tine-like region of the soil working tool.

  • Publication number: 20190241081
    Abstract: This disclosure relates to an energy storage arrangement for a vehicle. In particular, the energy storage arrangement includes a battery unit provided in an intermediate space between adjacent fluid tanks. Relative to the above-discussed prior art, this disclosure provides an improved energy storage arrangement which uses the otherwise unused intermediate space between two adjacent fluid tanks. Thus, this disclosure provides a space-saving, efficient, and cost-effective arrangement.

  • Patent number: 9631548
    Abstract: The application describes a system for an engine comprising a direct injection nozzle for injecting gaseous fuel into a cylinder of an engine in a second operating mode; an intake injection nozzle for injecting liquid fuel into an intake port of the engine in a first operating mode; and a valve gear suitable to adjust timing of opening and closing of an inlet valve. Preferential injection of a gaseous fuel such as compressed natural gas directly into the cylinder increases efficiency and allows for reduced heat exposure to the lesser used liquid gas injectors mounted in the intake port, reducing coking of these injectors.

  • Patent number: 9523326
    Abstract: Methods are provided for improving delivery of supercritical fuels via a direct injector. An injector control parameter is adjusted based on one of a fuel pump gain, an injected fuel mass, or a change in pressure in the fuel rail, and the engine operates the injector based on the adjusted parameter. Injector control parameters are only adjusted when fluid is subcritical at the fuel pump and when injector overlap is not present.

  • Patent number: 9525594
    Abstract: A method for transmitting software from a central computer to at least two further computers, includes connecting the central computer and the at least two further computers with a communication link for data transmission. The central computer sets up a connection to the at least two further computers and requests properties of the at least two further computers. The central computer transmits to the at least two further computers, which have been identified as having multicast capability, those parts of the software which are suitable for multicast transmission. The central computer sets up a unicast connection to the at least two further computers for those parts of the software not suitable for multicast transmission.

  • Patent number: 9512803
    Abstract: Various systems and methods for determining a start of fuel injection including a gaseous fuel in an internal combustion engine are provided. In one embodiment, an end of gas injection, a duration of gas injection, and a start of gas injection in an induction pipe of a cylinder of an internal combustion engine is determined based on one or more operating parameters. An earliest possible start of gas injection is further determined, and if the start of gas injection is before the earliest possible start of gas injection, at least one of the one or more operating parameters is modified such that the start of gas injection does not occur before the earliest possible start of gas injection.

  • Patent number: 9453474
    Abstract: A method, comprising: during engine cylinder operation with fuel from a first injector and not a second injector: increasing a rail pressure of a fuel rail coupled to the second injector in response to a temperature increase of a tip of the second injector. In this way, by raising the rail pressure of a fuel rail coupled to the second injector in response to a temperature increase of a tip of the second injector, the method may be utilized to prevent a vapor space from forming within the tip of the second injector which is exposed to the heat of combustion within the engine cylinder. By preventing a vapor space from forming, the method may be used to prevent fuel distillation in the tip of the second injector during periods where the engine cylinder is operating with fuel from a first injector and not the second injector.
