A radar detector suppresses alerts from vehicle guidance systems, by sweeping for a consistent radar signal; the center frequency of the signal is stored and the detector suppresses warnings of radar signals near that frequency. The detector uses an enhanced method for suppression of signals near a known location of a false signal source; in the event the detector detects a radar signal and finds a matching stored false signal, the detector will first compare the strength of the received signal to a threshold strength that is computed based upon the distance of the detector from the stored false signal, and will only suppress signals below threshold. The detector includes a camera directed to the road in the vicinity of the vehicle. Image data from the camera is processed to identify police vehicles as identified by flashing lights, a profile including a rooftop light bar and/or highly contrasting colored panels.

Motorcycles in a group action share group information to which each of motorcycles belongs and the motorcycles share information with a surrounding four-wheeled vehicle via a vehicle-to-vehicle communication. The information to be shared is the group information. Information from the motorcycle to the four-wheeled vehicle is transmitted when the four-wheeled vehicle is detected by an imaging unit included in the motorcycle or transmitted when a detection unit irradiated from the four-wheeled vehicle is detected.

A vehicle camera system and method for operating a vehicle camera system comprising a vehicle camera with communication capabilities. The vehicle camera operating in conjunction with other components to provide information to users. The vehicle camera system compiles information from multiple components into a single repository of video recordings with information, such as location information, vehicle status and diagnostic information, alert information and other information.

A computing device in a vehicle can emit a sequence of light pulses having a first speed, then receive a signal from another vehicle. Following this, the computing device can emit a message as a sequence of light pulses having a second speed based on the signal received from the vehicle, wherein the first speed is different from the second speed.

A method and apparatus are provided for detecting a RADAR signal. RADAR channel data in a frequency range is received, where the frequency range is divided into a plurality of equally wide channels. The received RADAR channel data is digitally processed and analyzed to identify a signal in the RADAR channel data in the frequency range. The frequency range is advanced to a next channel of the plurality of channels, where the frequency range of the next channel of the plurality of channels is non-sequential with the frequency range of the first channel. The steps of receiving, processing, and analyzing are repeated for the next channel of the plurality of channels.

A display and operating unit (1) for a vehicle, in particular a conventional bicycle or a light electric vehicle such as an e-bike or an electric scooter, comprises a display device (2) that is configured to display information about an operating state of an electronic component of the vehicle, a first operating element (3) for manipulating the operating state of the electronic component in response to operation of the first operating element (3), and a second operating element (4) for manipulating a display of a display device (21) of a display and operating device (20) that is separate from the display and operating unit (1) in response to operation of the second operating element (4).

A system for detecting GNSS signal jammers to be positioned on a roadside, the system comprises: a first device for receiving a GNSS signal; a second device that is configured to measure at least one characteristic of a received GNSS signal and to detect, on the basis of at least one characteristic, interference in the GNSS signal caused by a jamming signal; a third device for triggering the capture of an image of the road if the GNSS signal is subject to interference caused by a jamming signal, the first device configured to receive, via a radio link, a sequence of a satellite radionavigation signal received by a vehicle and retransmitted by the vehicle to the system via the radio link.

A method of processing data at a server 302 for maintenance of a database 516 of points of interest, such as speed limit enforcement devices. Each of the devices represented in the database has at least one attribute and a confidence value indicative of the accuracy of the at least one attribute associated therewith. The confidence value is time dependent and varies according to a predefined decay function. A report 500 relating to an attribute of a speed limit enforcement device is received at the server 302 from a mobile device 200. The confidence value associated with the speed limit enforcement device is adjusted in accordance with the received report, and information relating to the speed limit enforcement device 520, 522 is selectively transmitted to the or another mobile device 200 based on the confidence value.

A vehicle camera system and method for operating a vehicle camera system comprising a vehicle camera with communication capabilities. The vehicle camera operating in conjunction with other components to provide information to users. The vehicle camera system compiles information from multiple components into a single repository of video recordings with information, such as location information, vehicle status and diagnostic information, alert information and other information.

The invention relates to a device for warning of radar traps or speed radar signals, comprising a radar detection antenna, a central processing unit, which is connected to the radar detection antenna, an alert device or unit, which is connected to the central processing unit and which is designed for delivering an alarm, wherein the central processing unit is designed for determining at least one characteristic of the signal received by the radar detection antenna and for causing the alert device to deliver an alarm or suppress the delivery of an alarm in dependence on least one determined characteristic.
