A method for preventing or mitigating rear-end collisions of a motor vehicle and potential multiple vehicle collisions includes locating, by a sensor system of the motor vehicle, an obstructing vehicle in the front of the motor vehicle located on a trajectory of the motor vehicle, the obstructing vehicle being characterized by a speed below a predetermined first speed threshold, equal to zero; braking the motor vehicle, by an automatic braking system of the motor vehicle, to stop at a predetermined safety distance from the obstructing vehicle; monitoring, by the sensor system, the rear of the motor vehicle for a trailing vehicle approaching the motor vehicle from behind, wherein the sensor system is configured to detect driving information of the trailing vehicle; and performing safety measures by a control system of the motor vehicle in case a rear-end collision is anticipated based on the detected driving characteristics of the trailing vehicle.

A vehicular collision avoidance system includes a remote communicator disposed exterior and remote from the vehicle and operable to communicate information regarding location and motion of the remote communicator relative to the vehicle. A receiver at the vehicle receives a communication from the remote communicator, and a control at the vehicle includes a processor that processes information communicated by the remote communicator and received at the receiver. The control, responsive to processing communicated information, determines the location and motion of the remote communicator relative to the vehicle. A side sensing device is disposed at a side of the vehicle and operable to capture data, which is processed to determine approach of the remote communicator to the vehicle. Data captured by the side sensing device and information communicated by the remote communicator are processed at the control to determine a potential collision between the remote communicator and the vehicle.

Reflective, self-supporting road signaling device comprised of a support piece (A) and a signaling plate (B). The support piece (A) is made of a rigid triangular element with a clamp fastening onto the upper part of a vehicle window to support the signaling plate (B). As for the signaling plate (B), it is comprised of a long rectangular piece with a large positioning area for the reflective element (8). To ensure the signposted vehicle is easily seen by traffic on its same side, a reflective arrow changing color between red and white, with the arrow vertex as far as possible from the vehicle that carries it, is used.

An automated operation vehicle control unit is configured to perform a detection process in which an abnormal condition of a passenger of a vehicle is detected and a notification process in which pedestrians are notified of the abnormal condition detected in the detection process in a case where the abnormal condition of the passenger is detected in the detection process.

A retrofit trailer board system for vehicles is disclosed, including a trailer board carrying a plurality of signalling lights on a surface thereof, and a relaying control unit which is connected between the trailer board and a plurality of optical sensors. Each optical sensor is arranged for removable connection to the exterior surface of respective vehicle lights, each sensor being configured to issue a signal responsive to operation of a vehicle light.

A lighting apparatus includes a light-sheet assembly configured to conform to the rooftop. The light-sheet assembly extends at least one-half the length of the rooftop, and further extends at least one-half the width of the rooftop when mounted to the rooftop. The light-sheet assembly further includes a plurality of light emitting diode (LED) lights that are distributed about the rooftop when the light-sheet assembly is mounted to the rooftop. A controller is communicably coupled to the light-sheet assembly and configured to operate the plurality of LED lights. A roof-mount is affixed to the light-sheet assembly and configured to mount the light-sheet assembly to the rooftop of the emergency vehicle. The lighting apparatus is useful for emergency vehicles.

Systems and methods are directed to signaling status of an autonomous vehicle to a rider or potential rider. In one example, a computer-implemented method for communicating autonomous vehicle status includes obtaining, by a computing system comprising one or more computing devices, data associated with a state of an autonomous vehicle. The method further includes determining, by the computing system, one or more vehicle indications indicative of the state of the autonomous vehicle based at least in part on the data associated with the state of the autonomous vehicle. The method further includes providing, by the computing system, control data for one or more visual indicators associated with the autonomous vehicle to communicate the one or more determined vehicle indications.
