摘要:
A computer-implemented method of gathering data includes querying, via a vehicle computing system, a plurality of weather sensors included with a vehicle and in communication with a vehicle network. The method also includes determining whether or not appropriate conditions exist for storage of data from the sensor, for each of the sensors. Additionally, the method includes storing the data from the sensor if appropriate conditions exist. Finally, the method includes sending, from the vehicle computing system to a remote network, data from one or more queried sensors and current GPS coordinates of the vehicle.

Methods and systems are provided for adjusting an engine output delivered in response to an operator pedal actuation based at least on a grade of vehicle travel. During uphill travel, in the presence of headwinds, and/or in the presence of a vehicle payload, the output may be increased while during downhill travel or in the presence of tailwinds, the output may be decreased. In this way, driver fatigue during travel over varying elevations, varying ambient conditions, and varying loads can be reduced.

An emotive advisory system for use by one or more occupants of an automotive vehicle includes a computer. The computer is configured to receive input indicative of an operating state of the vehicle. The computer determines at least one of a need to provide time information to an occupant based on the operating state of the vehicle and an occupant request to provide time information to the occupant. The computer generates data representing an avatar having an appearance, and data representing a spoken statement for the avatar. The spoken statement provides time information to the occupant in spoken dialog based on at least one of the need and the request. The computer outputs data representing the avatar for visual display, and data representing the statement for the avatar for audio play.
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.
摘要:
A system or method for controlling a multiple cylinder internal combustion engine operable in a reduced displacement mode with at least one valve or cylinder selectively deactivated include monitoring valve operation by analyzing camshaft position to detect valve operation inconsistent with a current cylinder state (activated or deactivated) and controlling the engine in response to detecting the inconsistent operation. The camshaft position may be used to produce a surrogate signal indicative of intake/exhaust valve lift generated using camshaft sensor tooth deviation relative to an expected or reference tooth position for a corresponding crankshaft position and compared to a corresponding threshold. The surrogate signal indicative of valve lift may also be generated by pattern matching or correlation of one or more reference tooth position patterns to a measured or inferred tooth position pattern.

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.
