20140316656 | STEERING SYSTEM CLATTER MITIGATION - A steering system clatter mitigation apparatus and method. The clatter mitigation apparatus excites the steering system at a frequency within a range of an existing engine noise. The excitation of the steering system at a different frequency than the clatter sound greatly reduces the clatter sound. The sound produced by the excitation of the steering system is masked by the existing sound of the engine. | 10-23-2014 |
20150090519 | SEMI-DECOUPLED STEERING SYSTEM - A steering system for a vehicle is disclosed. The steering system may have a steering linkage and a controller. When operation of the steering system is within a predefined relative rotational range, the controller may be programmed to translate steering motion to a steering gear box through a motor. Operation of the steering system outside the predefined rotational limit actuates the steering linkage. Once the steering linkage is actuated, steering motion is translated to the steering gear box directly through the steering linkage. | 04-02-2015 |
20150094939 | POWERTRAIN CONTROL SYSTEM - Systems and methods are described for powertrain controls optimization. One method comprises adaptively learning engine settings for a sparse sample of a speed-load map, which includes engine operation at boundary conditions of a speed-load map, and generating a dynamic node look-up table based on the learned engine settings for the sparse sample. The dynamic node look-up table may provide engine settings for engine operation at speed-load points not explicitly learned during the adaptive learning. | 04-02-2015 |
20150112547 | ROAD CHARACTERISTIC PREDICTION - A vehicle system includes at least one sensor that collects infrastructure information in real time and outputs sensor signals representing the collected infrastructure information. A processing device processes the sensor signals, predicts a future road characteristic based on the infrastructure information, and controls at least one vehicle subsystem in accordance with the predicted future road characteristic. A method includes receiving infrastructure information collected in real time, processing the infrastructure information, predicting a future road characteristic based on the infrastructure information, and controlling at least one vehicle subsystem in accordance with the predicted future road characteristic. | 04-23-2015 |
20150112548 | ROAD CHARACTERISTIC PREDICTION - A vehicle system includes at least one sensor and a processing device. The sensor is configured to output sensor signals representing infrastructure information collected in real time. The processing device is configured to predict a future road characteristic based on the infrastructure information, evaluate a prediction error, adjust a prediction horizon until the prediction error is within a predetermined accuracy range, and control at least one vehicle subsystem in accordance with the predicted future road characteristic. A method includes receiving infrastructure information collected in real time, predicting a future road characteristic based on the infrastructure information, evaluating a prediction error, adjusting a prediction horizon until the prediction error is within a predetermined accuracy range, and controlling at least one vehicle subsystem in accordance with the predicted future road characteristic. | 04-23-2015 |
20160063045 | Method and Apparatus for Road Risk Indices Generation - A system includes a processor configured to gather historical risk-affecting data with respect to a current road. The processor is also configured to gather current risk-affecting data with respect to the current road. Further, the processor is configured to generate a baseline risk index for the road based on the historical data. The processor is additionally configured to modify the baseline risk index based on the current data and provide a risk index value for the current road based on the modified baseline risk index | 03-03-2016 |
20160096526 | ENHANCED VEHICLE SPEED CONTROL - A demand is identified based on input from a vehicle operator. Data is received providing a history of vehicle velocities. An estimated reference velocity is generated based at least on the velocity data. A final demand is generated based at least in part on a reference velocity indicated by the velocity control signal and the estimated reference velocity. | 04-07-2016 |
20160096527 | ADAPTIVE MODEL PREDICTIVE CONTROL FOR VEHICLE ROUTE PLANNING - Method and system are provided for vehicle route planning based on adaptive model predictive control. In one example, a method may include real-time online identification of the vehicle model base on the vehicle inputs and outputs; compression of the input space to increase the optimization efficiency; and optimization of the route planning based on the model parameter of the vehicle and the known road grade. | 04-07-2016 |
