20120330508 | SYSTEM AND METHOD FOR CONTROLLING ELECTRIC POWER STEERING ASSIST - An automotive vehicle may include an engine, an electric power steering system and at least one controller. The at least one controller may, during an auto stop event of the engine, reduce at a first rate an available electric power steering system current to a non-zero threshold value before fuel to the engine is shut off and reduce at a second rate different than the first rate the available electric power steering system current from the non-zero threshold value to 0 after fuel to the engine is shut off. | 12-27-2012 |
20120330529 | ENGINE AUTO STOP AND AUTO START STRATEGIES - An automotive vehicle includes an engine and at least one controller. The at least one controller receives information about steering angle velocity or steering input torque during an engine auto stop event, and determines whether to allow the engine to auto stop based on the received information. | 12-27-2012 |

The at least one controller periodically determines an estimated current to be demanded by vehicle electrical loads during an auto stop of the engine, compares the estimated current with a threshold current, and inhibits an auto stop of the engine if the estimated current is greater than the threshold current for a predetermined period of time. | 01-17-2013 |
20130041556 | METHOD AND SYSTEM FOR ENABLING ELECTRICAL LOADS DURING AN ENGINE AUTO START - An automotive vehicle includes an engine, a plurality of electrical load subsystems, and at least one controller. During an auto start of the engine, the at least one controller detects a starter disengage condition. In response to detecting the starter disengage condition, the at least one controller periodically determines a value of an operating parameter associated with the vehicle, causes a first subset of the electrical load subsystems to be enabled when the value of the operating parameter falls with a first predefined range of values, and causes a second subset of the electrical load subsystems to be enabled when the value of the operating parameter falls within a second predefined range of values. | 02-14-2013 |
20130268182 | ENGINE OPERATION FOR PLUG-IN HYBRID ELECTRIC VEHICLE - A method, comprising propelling a vehicle with an engine and a motor starting the engine if energy stored in an energy storage device is greater than an upper threshold level when a contaminant amount in the engine oil is greater than a threshold amount. In this way, it is possible to harmonize fuel degradation along with oil degradation, while still providing efficient vehicle and engine operation | 10-10-2013 |
20140235406 | STOP-IN-PARK CONTROL FOR MICRO-HYBRID VEHICLES - A stop/start system of a micro-hybrid vehicle may selectively initiate an engine auto start in response to a PRNDL gear lever/transmission being moved/shifted out of DRIVE after an engine auto stop and a determination that the vehicle is located, for example, in an intersection or railroad crossing prior to the PRNDL gear lever/transmission being moved/shifted into REVERSE. | 08-21-2014 |
20140236459 | STOP/START CONTROL TO INCREASE MICROHYBRID VEHICLE BATTERY CHARGE - A stop/start system of a vehicle autostops and autostarts an engine and, in response to an identification of a drive cycle destination indicating that the vehicle will remain parked for at least a predefined period of time, prevents autostopping of the engine during the drive cycle to increase a state of charge of the battery above a nominal target state of charge. | 08-21-2014 |
20140257637 | CONTROL FOR STOP/START VEHICLE WHEN APPROACHING CONTROLLED INTERSECTIONS - A controller in a stop/start vehicle may anticipate a vehicle stop and engine shutdown event in response to detecting a vehicle approach to an intersection. The controller may disable a power steering system or otherwise prepare vehicle subsystems for shutdown prior to the anticipated shutdown event. The controller may also enable the power steering system in response to anticipating an automatic restart event. | 09-11-2014 |
20140257677 | STOP/START CONTROL FOR STOP/START VEHICLE IN TURN LANE - An engine of a stop/start vehicle, after the engine has been automatically stopped, may be commanded to automatically restart in response to detecting that the vehicle is in a turn lane based on traffic data in a vicinity of the vehicle such that the engine is automatically restarted before a brake pedal is released and a steering wheel is turned. | 09-11-2014 |
20140257678 | AUTO-STOP CONTROL FOR A STOP/START VEHICLE NEAR WATER - A stop/start vehicle includes an engine and a stop/start system that prevents an auto stop of the engine when a speed of the vehicle is approximately zero in response to the vehicle being located within a specified distance from a body of water or in response to the vehicle being located in a user identified geographic region. | 09-11-2014 |
20140257679 | AUTO-STOP CONTROL FOR A STOP/START VEHICLE AT A SERVICE LOCATION - A stop/start vehicle includes an engine and a stop/start system that prevents an auto stop of the engine when the speed of the vehicle is approximately zero in response to the vehicle being located at a service location or in response to the vehicle being located in a user identified geographic region. | 09-11-2014 |
20150019054 | METHOD AND SYSTEM FOR A PLUG-IN HYBRID ELECTRIC VEHICLE - Methods and systems are provided for displaying a recommended engine fuel fill amount to an operator of a plug-in hybrid electric vehicle. In one example, the recommended engine fuel fill amount is determined based on an actual amount of fuel consumed over a particular duration and displayed to an operator of the vehicle with a low fuel warning. | 01-15-2015 |
