摘要： Aspects of the disclosure relate to methods, systems, and non-transitory computer readable media for the actuation of vehicle systems. A vehicle actuation command that includes an indication of a requesting entity and vehicle systems a requesting entity is authorized to actuate may be received. There may be a determination of whether a vehicle actuation command is valid and based on a vehicle actuation command being valid there may be a determination of whether a requesting entity is authorized to actuate a vehicle's systems. Based on a requesting entity being authorized to actuate a vehicle's systems, there may be a determination of whether a vehicle is in a safe operational state that will allow a vehicle actuation command to be safely implemented by a vehicle's systems. Furthermore, based on a vehicle being in a safe operational state, a vehicle systems indicated in a vehicle actuation command may be actuated.

摘要： Disclosed herein are systems and methods, implementable in a vehicle equipped with adaptive cruise control, for maintaining in a subject vehicle substantially constant following distance relative to a preceding target vehicle where there has been a change in slope of a surface on which the subject vehicle is travelling and/or where pitch of the subject vehicle has changed. Systems and methods disclosed herein may maintain such substantially constant following distance by managing degree of engine braking. Such engine braking management effective for maintaining substantially constant following distance relative to a preceding target vehicle, notwithstanding change in driving surface slope and/or change in pitch of the subject vehicle, may be realized based on data received into the subject vehicle's electronic control unit through sensors for detecting surface slope and sensors for detecting vehicle pitch, which may be located on the subject vehicle.

摘要： A method of monitoring an exhaust system of an engine having an engine control unit including a diagnostic module operatively associated with the engine comprises providing an exhaust gas recirculation valve connected with the engine control unit within the exhaust system. Position of the exhaust gas recirculation valve is automatically monitored during operation of the engine. Position of the exhaust gas recirculation valve is determined. Determined position of the exhaust gas recirculation valve is transmitted to the diagnostic module.

摘要： An apparatus for reducing obstruction compromising operation of at least one sensor having a portion disposed through skin of a vehicle, the portion having a surface offset from the skin comprises a member disposed offset from the surface. The member includes a first side having an inner surface and an outer surface that opposes the surface of the portion, and a second side having a second side inner surface and a second side outer surface. The second side outer surface faces exterior of the vehicle. A space is disposed between the second side inner surface and the inner surface. Ports are pneumatically connected with the space, a source of compressed air and a vent.

摘要： Disclosed herein are systems and methods, implementable in a vehicle equipped with adaptive cruise control, for maintaining in a subject vehicle substantially constant following distance relative to a preceding target vehicle where there has been a change in slope of a surface on which the subject vehicle is travelling and/or where pitch of the subject vehicle has changed. Systems and methods disclosed herein may maintain such substantially constant following distance by managing engine torque. Such engine torque management effective for maintaining substantially constant following distance relative to a preceding target vehicle, notwithstanding change in driving surface slope and/or change in pitch of the subject vehicle, may be realized, according to the subject vehicle's torque map, based on data received into the subject vehicle's electronic control unit through sensors for detecting surface slope and sensors for detecting vehicle pitch, which may be located on the subject vehicle.

摘要： The present disclosure relates to improved systems and methods for use in connection with maintaining the coolant system of a vehicle. Specifically, the present disclosure relates to improved systems and methods for monitoring the integrity of the coolant system in an engine, including capabilities for diagnosing leaks, degradation of coolant, open and/or loose radiator caps, and other sources of potential malfunctions. Early diagnosis and continuous monitoring of an engine coolant system results in earlier repairs and less vehicle downtime.

摘要： An electrical energy recovery, storage, and distribution system that may be used in a vehicle. The system may include a supercapacitor configured to quickly store large amounts of energy. The system may also include multiple circuits operating at different voltage levels, such that an output voltage from the supercapacitor is useful over a larger voltage range and the system is more energy efficient.

摘要： A stabilizing arrangement of a cooling system module of a vehicle includes stabilizer pins attached to the vehicle cooling system module. Stabilizer slots are incorporated into a component of the chassis of the vehicle, such as a frame extender. The stabilizer slots may be formed as an upwards opening U-shape. Bushings are attached to the stabilizer pins. The stabilizer pins and bushings extend laterally into and engage with the stabilizer slots. Upon installation, the stabilizer pins and bushings are aligned with the stabilizer slots as the cooling system module is lowered onto the ISO mounts. The stabilizer pins and bushings slide vertically downwards into the stabilizer slots as the cooling system module is lowered into place. The simpler stabilizer pins, bushings, and stabilizer slots thereby take the place of expensive, time consuming, complex, labor intensive, and space consuming stay rod arrangements.

摘要： The Method and Arrangement for Predicting Engine Out Nitrogen Oxides (EONOx) includes training multiple candidate Artificial Neural Network (ANN) architectures using training data, and then selecting an ANN architecture from the candidates using an automated ANN architecture selection algorithm and testing data. An intelligent EONOx prediction or estimation system using the selected ANN architecture then provides an EONOx output variable, which is used along with the output of an EONOx sensor. The system is deployed into the engine controller. The training and testing sets of data include input variables from engine sensors and/or actuators that relate to EONOx, and may be acquired by testing a target engine. Selecting the optimal ANN architecture may be based on Root Mean Squared Error (RMSE) analysis using the automated ANN architecture algorithm and the training set of data.

摘要： A compression ratio varying arrangement of an engine is adapted to work with a crankshaft having at least one crankpin offset from the centerline of the crankshaft. An eccentric has an internal bore engaged with the crankpin, and an external cylindrical surface that has a centerline that is offset from the centerline of the internal bore. A connecting rod is engaged with the external cylindrical surface of the eccentric, and a piston is connected to the connecting rod. An eccentric lever is attached to the eccentric. A compression ratio adjustment link is connected to the eccentric lever. A compression ratio adjustment mechanism is connected to the compression ratio adjustment link. The compression ratio adjustment mechanism controls the orientation of the connecting rod eccentric, and thereby the compression ratio of the engine, by extending or retracting the compression ratio adjustment link.
