20130238203 | DRIVE FORCE CONTROL FOR VEHICLE - Systems, methods and controllers for facilitating or providing a more efficient operation of a vehicle are disclosed. An accelerator input is detected from an accelerator sensor and it is determined whether the accelerator input is within a first range of values or within a second range of values. If it is determined that the accelerator input is within the first range of values, an engine is controlled to provide limited or no power to a transmission. If it is determined that the accelerator input is within the second range of values, the engine is controlled to provide a substantially constant power to the transmission. | 09-12-2013 |
20140200777 | HYBRID VEHICLE AUTOMATIC SIMULATED SHIFTING - A system for simulated shifting for a hybrid vehicle, the system includes a plurality of wheels, an engine, a sensor, a transmission, a memory for storing target engine speeds and deceleration torques for a plurality of simulated gears, and a processor. The engine provides a torque to the plurality of wheels. The sensor detects a requested deceleration torque. The transmission simulates a current simulated gear by delivering an applied torque, which corresponds to the requested deceleration torque, to the plurality of wheels and an engine speed corresponding to the simulated gear. The processor simulates a downshift by increasing an engine speed of the engine without changing the applied torque to the plurality of wheels when the requested deceleration torque exceeds a deceleration torque of a lower simulated gear. | 07-17-2014 |
20140200793 | SYSTEM AND METHOD FOR DETERMINING AND DISPLAYING A FUEL-EQUIVALENT DISTANCE-PER-ENERGY CONSUMPTION RATE - A method and system for determining and displaying a rate corresponding to the distance travelled by a vehicle per an amount of fuel-equivalent energy consumption, and more particularly for determining and displaying a number of miles or kilometers travelled per a gallon or a liter of total fuel and fuel-equivalent non-fuel energy consumed. The system includes an electronic control unit, an engine, a fuel controller, a battery, a battery management and control unit and a display. The method and system determine the fuel-equivalent energy consumption sum based on a constant energy conversion factor or an energy conversion efficiency loss number or factor determined in real time. The method and system also determine and display a fuel-equivalent cost for travelling a kilometer or a mile of the distance travelled. The method and system also change an operation of the vehicle based on the determined rate and fuel-equivalent cost. | 07-17-2014 |
20140257608 | KNOWN ROUTE HV CONTROL COMPENSATION - A system and method for optimizing a fuel efficiency of a hybrid vehicle by learning from a route history. The system may be a hybrid vehicle including an engine, a motor-generator, a battery, a battery module, a GPS unit, a memory, and a processor. The method may include detecting a current route of the hybrid vehicle, calculating a confidence value corresponding to a probability that the current route has a match in the route history, detecting a battery state of charge (SOC), determining a target SOC based on the confidence value and the route history, and adjusting an engine start/stop threshold and/or an engine power request to achieve the target SOC. They system may learn and improve fuel efficiency over successive trips along the route. | 09-11-2014 |
20140257609 | HYBRID VEHICLE LAUNCH CONTROL - A launch control system which maximizes hybrid vehicle acceleration from a standing start. A hybrid vehicle includes wheels, an engine, a motor-generator, a processor, and an actuation device. The processor controls an engine speed and an engine torque independently from a wheel speed and a wheel torque. While the hybrid vehicle is at a standstill, the actuation device is switched to an on state, and the engine speed and engine torque is raised to optimal values. When the actuation device is subsequently switched to an off state, the engine speed and the engine torque is applied to the plurality of wheels to launch the hybrid vehicle. The processor blends or further adjusts the torque applied to the plurality of wheels to maximize the acceleration while optimizing an amount of wheel slip. The processor then learns the launch to improve performance on subsequent launches. | 09-11-2014 |
20140257643 | PARKING PAWL ENGAGEMENT CONTROL WITH FEEDBACK - A system and method for improving the consistency of a hybrid vehicle parking pawl engagement control. A hybrid vehicle includes a motor-generator, a planetary gear, a parking pawl, and a processor. The hybrid vehicle uses feedback to more accurately determine that the parking pawl is fully engaged. The parking pawl is applied to the planetary gear. The processor determines a target movement for the hybrid vehicle and commands a torque from the motor-generator to achieve the target movement. The processor determines that the parking pawl has fully engaged and locked the planetary gear. | 09-11-2014 |
