摘要:
A method for checking the integrity of GPS measurements for a moving vehicle includes determining a first inter-vehicle distance between a first vehicle and a second vehicle based on GPS measurements obtained at both vehicles, independently determining a second inter-vehicle distance based on relative motion of the first vehicle and the second vehicle obtained using INS sensors at both vehicles, and comparing the the first and second inter-vehicle distances. The integrity of the GPS measurements are checked if the first and second inter-vehicle distances are nearly equivalent. Methods for error detection and for mapping GPS multipath levels at each point in a vicinity for an entire range of satellite constellations are also described.

摘要:
A method and system for a wireless interface to the electronics of an automotive vehicle for a remote application in the vehicle or within communication range of the vehicle. The remote application may be a navigation system using vehicle motion sensor data to provide or improve a navigation solution for the vehicle. In an alternative embodiment, the remote application is diagnostic software running on a handheld computer that evaluates vehicle systems in a diagnostics procedure.

摘要:
A method for configuring a wireless network includes pointing a first end of a network configuration device at a wireless device and actuating the network configuration device to add the wireless device to the wireless network. The method may include positioning the first end in close proximity to the wireless device. A device is provided for configuring wireless networks that includes a transmitter configured to transmit at least one of an initiation signal and a connection table to a wireless device. The initiation signal is sent by the device to the wireless device to add or delete the wireless device from a network that is being configured. The connection table includes information about each wireless device that has previously been added to the network. A receiver is included in the device that is adapted to receive at least one of the connection table and a unique identifier from the wireless device. A memory is included in the device that is configured to store the connection table and electrically coupled to the transmitter and the receiver. The transmitter includes an infrared transmitter or a radio frequency transmitter and the receiver includes an infrared receiver or a radio frequency receiver. A system is provided that includes a pointing device including a connection table and a plurality of wireless network devices wirelessly couplable with the pointing device and with each other.

摘要:
A method and system is provided for a protocol translation device that may include two different protocols and an intermediate, network-independent protocol. In an embodiment, an emerging worldwide standard, Bluetooth, provides a wireless interface to the electronics in an automotive vehicle via the de-facto standard for vehicle buses, Controller Area Network (CAN). A remote application can connect to this interface via a Bluetooth host in the vehicle or in communication range of the vehicle.
