A method of processing a voice for a vehicle, a device, and a medium are provided, which relate to a field of voice recognition technology. The method of processing a voice for a vehicle includes: separating an initial voice data in response to receiving the initial voice data from a plurality of regions inside the vehicle, so as to obtain a plurality of voice sub-data and a description information for each voice sub-data of the plurality of voice sub-data, the plurality of voice sub-data correspond to the plurality of regions respectively, and the description information for each voice sub-data indicates the region corresponding to the each voice sub-data in the plurality of regions; and determining a voice working mode of the vehicle based on the plurality of voice sub-data.

An electronic control unit to control an engine control module of an engine is disclosed. The electronic control unit may receive a machine input associated with the engine. The electronic control unit may select, based on the machine input, a lug mapping from a plurality of lug mappings for controlling a load of the engine. The electronic control unit may control, using the lug mapping, power output of the engine and power to a propulsion module of the machine to satisfy a drawbar power/torque threshold and steering power torque threshold associated with the machine.

Provided herein is internal combustion engine system including: an internal combustion engine; a turbocharger turbine operatively connected to a turbocharger compressor; an air intake system; an exhaust gas system; an exhaust gas recirculation (EGR) conduit; an EGR valve; and a turbomachine arranged in the EGR conduit. Further, the EGR valve and the turbomachine are positioned in relation to each other in the EGR conduit such that a flow of high pressure exhaust gas through the EGR conduit towards the air intake system reaches the EGR valve before reaching the turbomachine; an additional exhaust gas conduit is arranged between the EGR conduit and a point of the exhaust system downstream the turbocharger turbine so as to allow exhaust gas to flow.

A method of controlling operation of an engine includes providing power to a control module and/or a controller included in the control module, providing an engine start input where the engine start input is communicated with the controller, determining or detecting actuation of the engine start input, sending a signal from the controller to begin an engine starting procedure to start the engine, providing multiple engine operating mode inputs via the module, determining or detecting actuation of one of the engine operating mode inputs, and controlling the engine in accordance with one or more predetermined engine control instructions associated with the engine operating mode that is associated with the actuated engine operating input.

A control system and method relating to operation of an internal combustion engine, particularly an engine for powering an unmanned aerial vehicle. The engine has a combustion chamber and a throttle for regulating fluid flow to the combustion chamber, the throttle being operable under the control of an electronic control unit. With the control system and method there are first and second modes optionally available for operation of the engine. In the first mode the engine is operable at a throttle setting set by a request from a first remote controller (e.g. a ground-based controller) via a second on-board controller. In the second mode the engine is operable at a prescribed minimum throttle setting asserted by the electronic control unit which limits the authority of the on-board controller. The engine is caused to operate in the second mode if a particular throttle setting determined from a request of the remote controller is less than the prescribed minimum throttle setting.

A method for operating an engine during a fuel cut-off mode is disclosed. The method may adjust exhaust valve opening timing and exhaust valve lift of one or more cylinders to heat air flowing through the one or more cylinders so that a temperature of an after treatment device may be maintained or increased.

Various systems and methods are provided for adjusting operating parameters of an internal combustion engine. In one example, a system may include adjusting an amount of advance of a fuel injection timing of a plurality of fuel injectors of an internal combustion engine relative to top dead center (TDC) responsive to engine output demand, where, as the engine output demand increases, the amount of advance first decreases and then increases. In this way, an amount of vehicle emissions may be decreased while an amount of fuel consumption is decreased.

A throttle assembly for an engine may include a remote throttle lever, a sensor, and a terminal. The remote throttle lever may be coupled physically to a user input device and operable to be moved under control of the user input device. The sensor is configured to detect a position of the remote throttle lever and generate an output signal indicative of the position of the remote throttle lever. The terminal configured to provide the output signal to a controller of the engine.

Systems and methods for reducing driver awareness of engine stoppage by a vehicle are disclosed herein. In an embodiment, the system includes a stop-start mechanism in communication with an engine operable to cause movement of the vehicle, the stop-start mechanism programmed to shut off the engine at a beginning of a nonoperational period and restart the engine at an end of the nonoperational period. The system also includes a vibration device triggered to cause at least one vehicle component to vibrate when the stop-start mechanism shuts off the engine at the beginning of the nonoperational period, and triggered to cease causing the at least one vehicle component to vibrate when the stop-start mechanism restarts the engine at the end of the nonoperational period.

A fuel level measurement system and method for liquified natural gas (LNG) powered machines is disclosed. An engine control module (ECM) receives fuel line pressure levels at a first time (e.g., a key-off event) and, again, at a second time (e.g., a key-on event). The ECM predicts an expected change in pressure from the key-off event to the key-on event based on various factors. If the change in pressure detected is greater than a threshold level different from the predicted change in pressure, the ECM determines a fill event and resets a current fuel level. The ECM tracks mass flow commands used to provide fuel to the engine to determine the consumption of fuel from the fuel tank and to determine a new current fuel level based on the amount of fuel consumed. The current fuel level is displayed on a fuel gauge.
