摘要： A system for sensing a potential collision of a first vehicle (11) with a second vehicle (72) that transmits a second position signal. The first vehicle has a pre-crash sensing system (10) includes a memory (14) that stores vehicle data and generates a vehicle data signal. A first global positioning system (18) generates a first position signal corresponding to a position of the first vehicle. A first sensor (20) generating sensor data signals from the first vehicle. A receiver (22) receives a second position signal and a road condition signal from the second vehicle. A countermeasure system (40) is also coupled within the first vehicle. A controller (12) is coupled to the memory (14), the global positioning receiver (18) the first sensor (20) and the counter measure system (40). The controller (12) determines a distance to the second vehicle in as a function of the second position signal. The controller determines a first vehicle trajectory from the sensor data signals and the position signal. The controller (12) determines a threat level as a function of the distance, the first vehicle trajectory and the road condition signal and activates the counter-measure system in response to the threat level.

摘要： A method is described for detecting moving and/or stationary objects in the path of a vehicle, where the distance and velocity of the reflecting object are determined by using a radar sensor, where the frequency of the signal transmitted is modulated in the shape of a ramp according to a multi-ramp method, and some ramps have a lower slope in the frequency curve. The higher spectral components of the mixed signals from the ramps having the lower slope, which are to be assigned to a distance range of the reflecting object which is greater than the distance range belonging to the ramps having the greater slope, are used to determine the distance, speed and angle of objects.

摘要： A radar apparatus of an automotive vehicle includes a radar unit which radiates an electromagnetic wave to a target in a forward direction of the vehicle and receives reflection beams from the target to detect the target. A scanning control unit performs a beam scanning of the radar unit to the target so that the reflection beams during the beam scanning are received. A center direction determining unit detects a distribution pattern of the received reflection beams with respect to respective scanning angles of the radar unit, performs a similarity approximation of the distribution pattern by using an antenna directional gain pattern of the radar unit to produce an approximated distribution pattern, and determines a direction of a center of the target based on a peak of the approximated distribution pattern.

摘要： A method via which the range of vision in a vehicle's field of view can be determined precisely, so that with the help of range-of-vision information the driver can be advised to modify his driving style. The contrast of an object detected by a radar or lidar sensor is measured by a monocular video sensor, and the range of vision is determined from the measured values supplied by the radar or lidar sensor and by the monocular video sensor. Alternatively, the distance to and contrast of at least one object can be measured by a binocular video sensor, the range of vision then being determined from the measured contrast and distance values.

摘要： A vehicular radar apparatus comprising a radar beam transmission device and a reception device, and a processing unit for detecting the position of a target object from transmission signals and reception signals. The processing unit has a preceding vehicle judgment circuit for judging if a vehicle travelling in front of a subject vehicle in the same direction is the same vehicle as previously detected or not, and a signal strength comparing device for comparing the signal strength of a current reception signal reflected from the preceding vehicle, with a signal strength of a reception signal reflected from the preceding vehicle a predetermined comparison reference time prior, to thereby calculate a change amount in signal strength. When the change amount calculated by the signal strength comparing device drops beyond a previously set threshold value and it is judged by the preceding vehicle judgment device that the preceding vehicle is the same vehicle, it is judged that the detection sensitivity of the radar apparatus has dropped.

摘要： When a radar device S1 detects an object existing ahead of a vehicle in the movement direction of the vehicle, a determining device M1 determines a possibility of contact of the vehicle with the object from the relative positional relationship between the vehicle and the object, based on the result of such detection. If it is determined there is the possibility of contact, an automatic braking device M2 operates a vacuum booster 2 to carry out an automatic braking operation to avoid the contact of the vehicle with the object. When a braking-will detecting device M3 detects a driver's braking will during the automatic braking operation by the automatic braking device M2, an emergency-degree presuming device M4 presumes a degree of emergency in the driver's braking will, and the automatic braking device M2 generates the braking force corresponding to the degree of emergency to assist in the braking operation of the driver. This enables a smooth switch-over from the avoidance of the contact by the automatic braking operation to the avoidance of the contact by the driver's braking operation, and a high braking force assisted by the automatic braking operation can be generated to effectively avoid the contact.

摘要： The marine Vessel Traffic System (VTS) is an improved radar harbor surveillance sensor, computer and display system that monitors marine harbor traffic, provides advisories to vessels in areas selected by the system operators, and provide the operators of the system with an early warning of unacceptable traffic conflicts in the confined waterways of the harbor. The VTS collects harbor traffic information from multiple remote sensor collection sites around the harbor and integrates, records, merges and presents the remote site data onto a single operator display, selected from a plurality of operator displays. VTS provides quick accurate computer generated graphic display of the harbor traffic, possible surface and subsurface conflicts, and key vessel identification information and the VTS documents incidents and traffic conditions for the Coast Guard or other waterway authorities.

摘要： A radar system adapted to be installed on a vehicle (1) is operable to detect objects in different fields of view of the system. The system has transceiver means (2, 3; 44, 46) for transmitting a radar signal and receiving the signal after the latter has been reflected from an object to be detected. A reflected signal is sampled by sampling means (12; 66) during a succession of sampling periods each of which is delayed with respect to a corresponding portion of the transmitted signal. The gating of the reflected signal effectively generates range shells, each of which corresponds to the time taken for a transmitted signal to reach an object at the shell, and to be reflected back to the system and is hence related to the delay between the transmission of the signal and the corresponding sampling period. The range shells define the field of view of the system, which can be changed by altering said delay. Such alterations are carried out under the control of control means which is connected to sensor means for detecting a property of the operation of the vehicle, determining a required position of the field of view, and setting the field of view of the system accordingly. The range shell positions, and hence fields of view, can also be changed by selecting alternative transmitters and/or receivers of the transceiver means. There is also shown a motor road vehicle which has a radar system comprising a pair of transmitter antennas at two alternate corner regions of the vehicle and a pair of cooperating receiver antennas of the other two corner regions. Certain embodiments of the system also have the facility to generate range shells which are swept over an area around the vehicle or which track detected objects.
