Abstract: 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.

Abstract: A method includes utilizing navigation data from a navigation system to segment a route to be travelled by a travelling vehicle into segments each having a road grade different than neighboring segments. The method further includes discharging a battery of the vehicle as the vehicle travels along an initial segment of the route according to a state-of-charge (SoC) set-point based on the road grade of the initial segment and a variable representative of the road grades of at least two other segments of the route.

Abstract: Periodic torque disturbances that affect cylinder valve operation are anticipated, and an appropriate reaction torque is provided by an electric motor to counteract the periodic torque disturbances to position a cylinder valve at a desired position.

Abstract: 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.

Abstract: 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.

Abstract: A method for operating an engine direct injection fuel system is provided. The direct injection fuel system includes a mechanical fuel pressure regulator that has a spring actuatable by an electric motor. The method includes adjusting a preload of the spring by operating the electric motor to adjust a set-point fuel pressure from a first set-point fuel pressure to a second set-point fuel pressure in response to an operating condition, and maintaining the preload of the spring mechanically when the electric motor is not operating.

Abstract: 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.
