摘要:
An automotive vehicle may include at least one controller configured to monitor a plurality of parameters representing a driver's dynamic control of the vehicle and to establish a reference range based on values of the monitored parameters during a first time period. The at least one controller may be further configured to detect a change in driver behavior condition when, during a second time period, a parameter derived from the monitored parameters falls outside of the reference range, and in response to detecting the change in driver behavior condition, to alter a response of the vehicle to driver inputs or to generate output representing a recommendation to alter a response of the vehicle to driver inputs.

A vehicle maintenance advisor system for use by a driver of an automotive vehicle includes a computer. The computer is configured to receive input indicative of a vehicle history. The vehicle history includes how the vehicle is driven over time. The computer is further configured to identify a need to advise the driver that the vehicle requires a maintenance service based on the vehicle history. An alert is output to the driver. The alert indicates the required maintenance service for the vehicle.
摘要:
Systems and methods are described, including one example method of controlling an engine having a cylinder with at least one valve operated by a variable valve mechanism (VVM) having a sensor coupled to the valve, the method comprising: adjusting at least one operating parameter in response to an indication of detonation of a combustible mixture in the cylinder, the indication based on the sensor coupled to the valve.

A method for controlling the air-fuel ratio of an internal combustion engine operating with alternating intake valves is presented. According to the method, engine air-fuel ratio can be adjusted by changing valve timings or fuel during a cylinder cycle.
摘要:
An arrangement of a four cycle internal combustion engine 7 is provided. In the preferred embodiment the engine 7 has a plurality of combustion chambers 18 having reciprocating pistons 22 mounted therein. A fuel injector 80 is provided for each combustion chamber. The fuel injector injects a stratified 80 charge into the combustion chamber 18 upon a compression stroke of the piston 22. An intake manifold 32 is provided to provide air to each combustion chamber. A charging device 38 is provided to pressurize the air within the intake manifold 32. Preferably the charging device is a variable geometry turbocharger 38. The pressurizing of the air within the intake manifold 32 allows the engine 7 to extend the stratified charge operation of the engine 7 and facilitates in increased gas mileage by allowing the engine 7 to stay in a stratified mode of operation longer than prior stratified charged internal combustion engines.
摘要:
A system and method for controlling an internal combustion engine include anticipating vehicle launch in response to vehicle position relative to a traffic stream and controlling automatic restart and shut down in response to an anticipated vehicle launch to prevent an automatic engine shut down or to initiate an automatic engine restart. Embodiments include determining vehicle position and traffic position using GPS coordinates. Automatic restart may be initiated in response to movement of a forward vehicle away from the vehicle or in response to a signal from a traffic control device, for example. Automatic shutdown may be inhibited in response to movement of a forward vehicle in cross traffic, in response to a turn indicator being active, or in response to wheel angle, for example.
摘要:
A path-dependent control of a hybrid electric vehicle (HEV) includes segmenting an original route into segments. A virtual route based on the remaining portion of the original route is generated once the HEV reaches a current segment of the original route. The virtual route includes a first segment corresponding to the current segment of the original route and a last segment representing at least two other segments of the remaining portion of the original route. Battery SoC set-points for the segments of the virtual route are generated. The vehicle is controlled according to the battery SoC set-point for the first segment of the virtual route as the vehicle travels along the current segment of the original route.
