20140213413 | ENGINE RESTART STRATEGY - A method of controlling a vehicle, where the vehicle includes an internal combustion engine and a transmission having a neutral state and an engaged state, includes setting the state of the transmission. The state of the transmission is set as the neutral state or the engaged state based on a restart condition, where the restart condition is one of: (i) a no wheel torque restart condition, and (ii) a wheel torque restart condition. The method additionally includes starting the engine. | 07-31-2014 |
20140303839 | USAGE PREDICTION FOR CONTEXTUAL INTERFACE - A vehicle interface system may include an interface configured to present icons representing selectable vehicle features; and a controller programmed to generate a score for each of the features based on a contextual variable including one or all of a vehicle location, vehicle speed, past feature usage information, and a predicted end location for the vehicle, and display certain of the icons and hide other of the icons based on the generated scores. | 10-09-2014 |
20150239450 | INFORMATIONAL BASED ENGINE STOP/START SENSITIVITY CONTROL FOR MICRO-HEV - A controller may be configured to adjust a brake apply and release detection calibration based on a detection sensitivity associated with a predicted driver start/stop intention for a vehicle and an associated confidence level indicative of a likelihood of the predicted driver intention; and perform at least one of engine startup and engine shutdown according to the adjusted brake pedal detection calibration. | 08-27-2015 |
20150246669 | METHODS AND SYSTEMS FOR HYBRID DRIVELINE CONTROL - Systems and methods for operating and hybrid driveline are presented. In one example, driver demand torque may be supplied to vehicle wheels via a hydraulic torque path and a friction torque path. Torque is distributed between the friction torque path and the hydraulic torque path in a way that ensures that driver demand torque is met and the friction torque path transfers torque up to its capacity. | 09-03-2015 |
20150251649 | ACTIVE MOTOR DAMPING CONTROL OF A HYBRID ELECTRIC VEHICLE POWERTRAIN - A hybrid electric vehicle includes an engine and an electric motor both configured to generate a vehicle powertrain torque and a controller programmed to control the powertrain torque for a limited duration in anticipation of a powertrain torque variation scenario using a damping function, wherein the damping function adjusts the vehicle powertrain torque based on a difference between a measured motor speed and a desired motor speed using the electric motor to counteract a powertrain speed oscillation. | 09-10-2015 |
20150266462 | SYSTEM AND METHOD FOR DETERMINING ENGINE DISCONNECT CLUTCH TORQUE - A system and method for estimating disconnect clutch torque during engine start with the motor in vehicles having an engine selectively coupled to the motor and transmission may be configured to control motor torque based on a clutch torque estimated from a difference in a measured powertrain state and a predicted powertrain state using motor torque as an input. The powertrain states may include, for example, motor speed, turbine speed, engine speed and clutch torque. An adaptive gain may be used to drive the difference between measured and estimated clutch torque toward zero. | 09-24-2015 |
20150266466 | Method and System for Adaptive Motor Power Loss Estimation in Hybrid Electric Vehicles - A control strategy for a hybrid electric vehicle powertrain having an engine, a motor, and a transmission includes operating the powertrain according to a motor power loss term that is adapted based on battery power supplied to the motor, motor power output, and an estimated motor power loss such that the motor power loss term changes over time and converges to a constant value to thereby be indicative of actual motor power loss. | 09-24-2015 |
20150276420 | CROWD SOURCED ENERGY ESTIMATION - A method of advising a driver of a vehicle may include at a computing system, receiving from the vehicle a predicted energy usage request for a selected route. In response to the request, the method may further include transmitting for each of a plurality of segments defining the selected route, an energy usage estimate based on data indicative of propulsive energy previously used by vehicles to travel the segments and to travel other segments having common characteristics with the segments. | 10-01-2015 |
