To provide a vehicle detection system capable of detecting a preceding vehicle traveling ahead of an own vehicle based on a position of an object by using an electromagnetic wave sensor while suppressing erroneous detection, an ECU determines if first and second positions detected by a millimeter wave radar are included in the same vehicle. The ECU designates calculated information of the preceding vehicle detected based on the first position as a calculation result if it determines that detection of the preceding vehicle is made based on the first position. The ECU uses calculated information of the preceding vehicle detected based on the second position as the calculation result when it determines that detection of the vehicle is not made based on the first position but the first and the second positions had been determined in the past as detected in the same vehicle.

The invention relates to a process for monitoring vehicles on a road by a system comprising at least one radar sensor and a second sensor different from the radar sensor, wherein the second remote sensor is a time-of-flight optical sensor or optical image sensor, the process comprising a temporal readjustment and a spatial matching in order to obtain a set of measurement points each assigned to first characteristics derived from the radar data and second characteristics derived from the optical data, the determination of the radar vehicle trackings and of the optical vehicle trackings, a comparison of similarity between the radar vehicle trackings and the optical vehicle trackings, the elimination of the radar vehicle trackings for which no optical vehicle tracking is similar, the process comprising monitoring a parameter derived from first characteristics of a retained radar vehicle tracking.

Disclosed is a digital sign system and method of use thereof. The system includes a digital sign having a controller board having a microcontroller, a temperature sensor communicably coupled to fans or a cooling/heating unit, an ambient light sensor, a GPS unit, a radar, a communication module, and a power source, wherein the controller board is in communication with an LED panel or another display module for digitally outputting messages, further wherein the digital sign is mounted on a pilot truck to allow the pilot truck to relay messages to a transport truck and oncoming vehicles. The digital sign is in communication with a second GPS unit disposed on the transport truck so as to track the real-time location of the truck. The digital sign measures the distance between a transport and the digital pilot truck sign and displays the relative distances between the two on the digital message board. In operation, the digital sign is configured to automatically adjust its brightness so as to optimize its visibility while reducing glare to other drivers on the road.

An autonomous driving display system includes: an autonomous driving control device to carry out autonomous driving; an autonomous driving display device display state of which is recognizable from outside a vehicle; and an in-vehicle device to make the autonomous driving control device carry out autonomous driving of the vehicle upon receiving an autonomous driving instruction signal instructing autonomous driving, monitor start of the autonomous driving of the vehicle by the autonomous driving control device, and control a display state of the autonomous driving display device to be in a display state different from a display state before the autonomous driving is started when the autonomous driving of the vehicle is started by the autonomous driving control device.

A vehicle traveling control apparatus includes an obtaining unit, a detector, and a controller. The obtaining unit obtains traveling environment information. The traveling environment information includes at least lane line information of a lane along which an own vehicle travels and preceding vehicle information. The detector detects traveling information of the own vehicle. The controller performs a steering control on a basis of the traveling environment information and the traveling information. When the obtaining unit obtains only the lane line information and when the obtaining unit obtains both the lane line information and the preceding vehicle information, the controller performs the steering control on a basis of the lane line information.

The method includes providing a central mapping server equipped with a server-side communication interface; providing at least one fleet vehicle of a vehicle fleet equipped with at least one sensor which is suitable for detecting mapping data, and with a vehicle-side communication interface, the server-side communication interface and the vehicle-side communication interface being configured to exchange data; making a mapping decision by decision-making logic implemented on the mapping server, and transmitting an individual mapping request which is based on the mapping decision to the at least one fleet vehicle, it being possible for the mapping request to include different pieces of information for individual fleet vehicles; and transmitting mapping data from the at least one fleet vehicle to the mapping server as a function of the individual mapping request and the use of the mapping data during the mapping of the route section.

The apparatus (e.g., a first radar device) may be configured to receive a second radar waveform from a second radar device; determine a transmission timing difference between a transmission time of a first radar waveform and a transmission time of the second radar waveform, where the first radar waveform may be transmitted by the first radar device; and generate a radar point cloud associated with one or more targets based on the received second radar waveform and the determined transmission timing difference. A second radar device may be configured to transmit a second radar waveform; receive, from one or more targets, one or more reflections of the second radar waveform; and transmit, to a first radar device, cooperative radar sensing information regarding the received one or more reflections.

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.
