Abstract:
A vehicle includes a navigation system and a processing device. The navigation system is configured to identify a current location of the vehicle, a destination location, and a distance between the current location and the destination location. The processing device is configured to identify a task, associate the task to the destination location, and schedule the task according to the distance from the destination location.
Abstract:
A selection for a shared vehicle is received. Whether the shared vehicle is in view of a user device camera is determined. At least one of directions to the shared vehicle are provided to the user device. Data of the shared vehicle are identified.
Abstract:
An apparatus and method for altering the drivability of a vehicle so as to alert a driver of the vehicle of a potentially hazardous condition. The vehicle has at least one sensor configured to detect the potentially hazardous potential. Additionally, the vehicle has a control system for directing a transmission of the vehicle to perform a transmission operation that catches the driver's attention by generating an acceleration or deceleration. The transmission operation is preferably an upshift, a downshift, an unlocking of a torque converter lockup clutch or a locking of the lockup clutch. In one embodiment, the control system directs the transmission to perform more than one transmission operation, the transmission operations defining a transmission operation cycle. In a preferred embodiment, more than one transmission operation cycle is performed. Potentially hazardous conditions include traffic in front of the vehicle, a second vehicle approaching from the rear, an upcoming curve in the road, an approaching speed limit or an upcoming banked portion of the road.
Abstract:
A driver interface system includes a processor programmed to receive driver interface tasks to be executed and to selectively delay or prevent at least some of the driver interface tasks from being executed based on a driver workload. The driver workload is derived from a variability of an activity level of a driver relative to a mean value of the activity level as represented by a recursively computed determinant of a covariance of the activity level.
Abstract:
A method of monitoring catalyst performance may comprise applying a set of parameter readings for a given sample to a support vector machine to generate a classification output, clustering the set of parameter readings to reduce a number of support vectors, computing a total fuel mass following a deceleration fuel shut-off event and an exhaust gas oxygen sensor switch and indicating catalyst degradation based on the total fuel mass.
Abstract:
A system includes a processor configured to project monitoring needs for a road segment. The processor is further configured to contact one or more vehicles traveling on the road segment during a time of monitoring need. The processor is additionally configured to instruct a first number, determined based on a projected monitoring need, of contacted vehicles to being monitoring and reporting traffic data for the road segment.
Abstract:
A method for tuning a vehicle's performance may include measuring a plurality of parameters representing the vehicle's current handling condition and the vehicle's limit handling condition, determining a margin between the vehicle's current handling condition and limit handling condition, characterizing the driver's dynamic control of the vehicle based on the margin, and altering at least one tunable vehicle performance parameter based on the characterization.
Abstract:
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.
Abstract:
A vehicle's dynamic handling state, driver inputs to the vehicle, etc. may be examined to determine one or more measures of driver workload. Driver interface tasks may then be delayed and/or prevented from executing based on the driver workload so as to not increase the driver workload. Alternatively, driver interface tasks may be schedule for execution based on the driver workload and caused to execute according to the schedule, for example, to minimize the impact the executing driver interface tasks have on driver workload.
Abstract:
A method is described comprising modulating vehicle speed about a target speed by operating a vehicle with an engine at high output and then operating the vehicle with the engine off, and adjusting operation of a suspension system based on the vehicle operation with the engine at high output and the engine off to control vehicle pitch during the modulating of vehicle speed about the target speed.
