摘要： A method is provided for synchronizing time in an unsynchronized vehicle controller area network system. A master control unit receives a global time from a time synchronization source. The master control unit estimates a respective time delay in transmitting messages by electronic control units on each controller area network bus. The time delay is a difference between a time when a message is generated by a respective electronic control unit for transmission on a respective controller area network bus and a time when the message is transmitted on the respective controller area network bus. The global time is adjusted for each respective controller area network bus based on the estimated time delays associated with each respective controller area network bus. Global time messages from the master control unit are transmitted to each electronic control unit that include the adjusted global times for an associated controller area network bus.

摘要： A method and system for creating a sky visibility map, using data from a vehicle and its neighbors. A host vehicle with satellite-based navigation capability measures the quality of signals it receives from available satellites, where azimuth and elevation angles of the satellites are known from an ephemeris or almanac. The host vehicle also receives satellite signal data from surrounding vehicles via vehicle-to-vehicle communication. Using data from all of the vehicles, a sky visibility map is constructed, indicating where obstructions to satellite visibility exist for different locations. The sky visibility map is used to anticipate satellite signal quality. A driving environment classification can be used to configure other vehicle systems. The sky visibility map can also be constructed without using data from surrounding vehicles; the host vehicle can store its satellite signal data long-term and use it to estimate satellite visibility when returning to a location previously visited.

摘要： A method is provided for augmenting GPS data using an in-vehicle vision-based module. A vehicle position is determined utilizing position-related data obtained from a position module. A position error is estimated on a periodic basis. A determination is made whether the position error estimate exceeds a first predetermined error threshold. Tracking data is generated for the vehicle over a course of travel utilizing captured images from the in-vehicle vision based module. The tracking data is integrated with the position-related data to estimate the vehicle position in response to the position error estimate exceeding the first predetermined error threshold. A determination is made whether the position error estimate decreases below a second predetermined error threshold. The vehicle position is re-determined using only the position-related data when the position error estimate decreases below the second predetermined error threshold.

摘要： A system and method for calibrating a vehicle heading sensor, such as a yaw-rate sensor, when GPS signals are not available using a bias update model that employs a bias gain factor. In order for the bias update model to be accurate, the vehicle should be traveling relatively straight. One embodiment of the present invention uses three thresholds to determine if the vehicle is traveling straight. These thresholds include a yaw-rate threshold, a steering wheel angle threshold and a wheel speed threshold. If all three of the thresholds indicate that the vehicle is traveling straight, then the update bias model can be used to calibrate the yaw-rate sensor.

摘要： A portable and adjustable child potty is invented and described. The invention provides the perfect combination of utility, efficiency, and hygiene. The device can be adjusted to suit users of different ages and body sizes in terms of its height, width, and length. The invented device can be packaged to a Travel Size such that it takes very little space for transportation. Size adjustment and Travel size to usage size changes can be done using a series of easily adjustable locks that can be operated by hand without the use of particular tools. The device is constructed using pipes such that a length of each arm can be adjusted by moving parts of the arms with respect to each other and locking them at a preferred setting. The potty seat can also be folded and contracted to a Travel Size. The device uses a biodegradable and disposable bag to collect the waste. A particular embodiment of the device may include height adjustable arm rests and a back rest. The device may also be used with an optional activity surface. While adult supervision of the use is always required, the anti-roll base and pelvic belt provide additional stability for the use with young children.
