Method and apparatus for detecting position

Номер: US20120001800A1

Автор: Kazuomi Tachigi

Принадлежит: Kenwood KK

A position detecting apparatus includes a GPS receiver configured to catch one or more of GPS satellites and track one or more of the satellites while receiving a GPS signal or GPS signals from one or more of the satellites. A power supply controllably feeds power to the GPS receiver. A suspension time decider decides a suspension time in accordance with at least one of (1) the number of satellites caught by the GPS receiver and (2) the level of at least one of the received GPS signals, and determines whether or not the lapse of time during which the GPS receiver continues to track no satellite reaches a prescribed time. A suspension controller controls the power supply to suspend the power feed to the GPS receiver during a term equal in length to the decided suspension time in cases where the lapse of time reaches the prescribed time.

An apparatus and method for providing an improved heading estimate of a mobile device in a vehicle is presented. First, the mobile device determines if it is mounted in a cradle attached to the vehicle; if so, inertia sensor data may be valid. While in a mounted stated, the mobile device determines whether it has been rotated in the cradle; if so, inertia sensor data may no longer be reliable and a recalibration to determine a new relative orientation between the vehicle and the mobile device is needed. If the mobile device is mounted and not recently rotated, heading data from multiple sensors (e.g., GPS, gyroscope, accelerometer) may be computed and combined to form the improved heading estimate. This improved heading estimate may be used to form an improved velocity estimate. The improved heading estimate may also be used to compute a bias to correct a gyroscope.

Automatic Detection of Mode of Transportation by Analyzing Signal Strength of Received GNSS Signals and Speed

Номер: US20130307722A1

Автор: Shahram Rezaei

Принадлежит: Individual

Object of the present invention is to provide a method to reduce power consumption of location based services applications, that run on mobile devices, by utilizing processor and positioning resources only when location changes. A method also is provided for detecting or inferring mode of transportation of user of a GNSS-enabled mobile device, such as smart phone, tablet, etc. Modes of transportation consist of: traveling on foot, biking, motor biking, driving or riding on a car, riding on bus, and riding on train. This method is based on analyzing signal strength information of GNSS signals received at location of the user and speed. The latter is used to make distinction between travelling on foot, biking, and motor biking modes. GNSS signal cannot penetrate metal, therefore when the mobile device is inside a vehicle, such as car, bus, or train, GNSS signals that their path collides with roof or metal body of the vehicle would be weak and have low SNR.

Global Navigation Satellite System (GNSS) signals are first received and then down converted to an intermediate frequency (IF) and digitally sampled. The sampled signals are multiplied by a local replica of the incoming IF carrier (I ref generator and Q ref generator). The purpose is to remove the Doppler and move the results to baseband for later accumulation processing. Two parallel correlation kernel modules, one kernel assuming the navigation data D is 1 while the other assuming navigation data D=0 or (−1), are provided. The correlation kernel takes the code numerically-controlled oscillator (nco) phase of the prompt signal as input, and generates four output signals that are multiplied by the Doppler-removed incoming sample signal. An implementation of the pulsed signals accommodates navigation data D=1 and D=0 or (−1). 1.

A method of correlating a digital communications signal is described. In an example, a window is defined equal to a portion of an epoch of the digital communication signal. The digital communication signal is then correlated across the window. A determination is made as to whether a correlation peak results from the correlating. Timing parameters are then established for receiving additional digital communication signals in response to presence of the correlation peak.

A method for controlling a vehicle as it travels along a road includes processing at an ECU provided image data captured by a forward viewing camera and processing at the ECU a provided output indicative of a determined geographical location of the vehicle. Responsive at least in part to processing of the provided output, a geographically-derived path of travel of the vehicle is generated. Responsive to determination of a traffic lane in which the vehicle is traveling along the road, a camera-derived path of travel of the vehicle is generated. The vehicle is controlled based on (i) the geographically-derived path of travel of the vehicle and/or (ii) the camera-derived path of travel of the vehicle. The vehicle is controlled based on diminished weight of the geographically-derived path or diminished weight of the camera-derived path when a respective reliability level is below a threshold level.
