A method for operating a motor vehicle, in which an object situated in a sensor region is detected with the aid of a sensor in surroundings of the motor vehicle; A piece of position information relating to the object is created. The position information is retained when the object is moved out of the sensor region, due to a movement of the motor vehicle, the distance of the object to the motor vehicle not increasing. The invention further relates to a motor vehicle and a computer program product.

A radio transceiver for communicating with one or more transceiver equipped targets, the transceiver including; a transmitter for transmitting radio signals in a transmit frequency band, wherein the transmitter is arranged to transmit a data signal in case a transceiver equipped target is present and to transmit a dummy signal in case a transceiver equipped target is not present, a receiver for receiving radio signals in a receive frequency band, and a detector for detecting backscattered radio signals in the transmit frequency band, wherein the detector is arranged to estimate a distance to at least one target object based on the backscattered radio signals.

An electronic control device mounted on a vehicle includes a blind spot region specifying unit, an information obtaining unit, and a blind spot region dangerous event determining unit. The blind spot region specifying unit specifies a blind spot region that is not included in a detection range of a sensor mounted on the vehicle. The information obtaining unit obtains lane information of a road around the vehicle including the blind spot region. The blind spot region dangerous event determining unit judges assumed behavior of a latent obstacle that possibly exist in the blind spot region based on the lane information of the blind spot region and a positional relationship of the blind spot region on the road with respect to the vehicle.

A rear pre-crash system, RPCS, of a subject vehicle comprising a judgement logic adapted to trigger an RPCS warning signal in response to a detected radar signal reflected by a target vehicle approaching the subject vehicle from behind, wherein said judgement logic is configured to modify the triggering of the RPCS warning signal in detected specific traffic scenarios.

A traffic radar system comprises a first radar transceiver, a second radar transceiver, a speed determining element, and a processing element. The first radar transceiver transmits and receives radar beams and generates a first electronic signal corresponding to the received radar beam. The second radar transceiver transmits and receives radar beams and generates a second electronic signal corresponding to the received radar beam. The speed determining element determines and outputs a speed of the patrol vehicle. The processing element is configured to receive a plurality of digital data samples derived from the first or second electronic signals, receive the speed of the patrol vehicle, process the digital data samples to determine a relative speed of at least one target vehicle in the front zone or the rear zone, and convert the relative speed of the target vehicle to an absolute speed using the speed of the patrol vehicle.

A vehicle structure includes a body, a bracket provided on the body, a bumper cover attached to the bracket, and an object detection device attached to the bracket.

The technology relates to determining general weather conditions affecting the roadway around a vehicle, and how such conditions may impact driving and route planning for the vehicle when operating in an autonomous mode. For instance, the on-board sensor system may detect whether the road is generally icy as opposed to a small ice patch on a specific portion of the road surface. The system may also evaluate specific driving actions taken by the vehicle and/or other nearby vehicles. Based on such information, the vehicle's control system is able to use the resultant information to select an appropriate braking level or braking strategy. As a result, the system can detect and respond to different levels of adverse weather conditions. The on-board computer system may share road condition information with nearby vehicles and with remote assistance, so that it may be employed with broader fleet planning operations.

A radar sensor is described herein. In accordance with one example embodiment the radar sensor includes a transmitter for transmitting an RF signal and a receiver configured to receive a respective back-scattered signal from at least one radar target and to provide a corresponding digital radar signal. The radar sensor further includes a processor configured to convert the digital radar signal into the frequency do-main thus providing respective frequency domain data and to compress the frequency domain data. A communication interface is configured to transmit the compressed frequency domain data via a communication link operably coupled to the communication interface. Furthermore, respective and related radar methods and systems are described.

A vehicle includes a sensing device disposed at the vehicle so as to have an external field of view of the vehicle, configured to detect a target vehicle moving from the external field of view to a parking space and a plurality of stationary parked vehicles; a controller configured to obtain a first distance that is a width between the plurality of parked vehicles and a second distance that is a width between one parked vehicle of the plurality of parked vehicles and the target vehicle adjacent to the one parked vehicle; and a warner configured to output a warning signal based on a control command of the controller.

A driving assistance apparatus including an approach detection part detecting an approach of a railway vehicle along a travel path from a diagonally backward of a subject vehicle to the subject vehicle without using a road-to-vehicle communication, a notification part notifying a driver of information and a microprocessor. The microprocessor is configured to perform estimating a traveling direction of the subject vehicle at an intersection, and controlling the notification part so as to notify the driver of the approach of the railway vehicle when the traveling direction crossing the travel path is estimated and the approach of the railway vehicle to the subject vehicle is detected by the approach detection part.
