Controlling display of variable content sign
A system determines first content for presentation on a display within an environment when a speed of one or more vehicles within a field of view (FOV) of the display is less than a threshold speed and second content for presentation on the display when the speed of the one or more vehicles within the FOV is greater than the threshold speed. The second content is different than the first content. The system transmits at least one of the first content or the second content to the display.

Traffic control preemption according to vehicle aspects
An on-board unit (OBU) of a vehicle receives one or more data messages indicative of intersection geometry for an upcoming intersection along a roadway being traversed by the vehicle and traffic control status of a traffic control of the intersection. An outbound direction for the vehicle through the intersection is identified. A first traffic message is sent to preempt the traffic control to allow the vehicle to perform a maneuver to traverse the intersection in the outbound direction. The maneuver is indicated as complete and a second traffic message is sent to discontinue the preempt of the traffic control.
Vehicle/road interaction signal control method and apparatus
Provided are a vehicle/road interaction signal control method and apparatus, including: expanding the range of an intersection, extending to an upstream intersection along each approaching vehicle direction, and determining signal phases according to traffic flow conditions; acquiring the current speed and the current position of each moving target in each phase; according to the current speed and the current position of each moving target in each phase, calculating the time for each moving target to reach the intersection; according to the time for each moving target to reach the intersection, obtaining a time sequence of the moving targets in each phase for reaching the intersection; according to the time sequence of the moving targets in each phase for reaching the intersection, determining a release order and a release duration for each phase; sending information to onboard terminals.
Method and apparatus for determining driving strategy of a vehicle
A method for determining driving strategy of a vehicle includes obtaining localization information of the vehicle, a driving route of the vehicle, and a current driving velocity of the vehicle. The method further includes detecting and interpreting a current status of a traffic light. The method further includes recognizing a duration of the current status of the traffic light. The method further includes detecting a relevant stop line. The method further includes obtaining a distance between the stop line and the vehicle. The method further includes determining whether to change the current driving velocity according to the current status of the traffic light, the duration of the current status of the traffic light, the distance between the traffic stop line and the vehicle, and the current driving velocity. A data processing device for determining driving strategy of a vehicle is also provided.
Method for performing a vehicle assist operation
The technology relates to assisting large self-driving vehicles, such as cargo vehicles, as they maneuver towards and/or park at a destination facility. This may include a given vehicle transitioning between different autonomous driving modes. Such a vehicles may be permitted to drive in a fully autonomous mode on certain roadways for the majority of a trip, but may need to change to a partially autonomous mode on other roadways or when entering or leaving a destination facility such as a warehouse, depot or service center. Large vehicles such as cargo truck may have limited room to maneuver in and park at the destination, which may also prevent operation in a fully autonomous mode. Here, information from the destination facility and/or a remote assistance service can be employed to aid in real-time semi-autonomous maneuvering.
Autonomous driving system and method of vehicle using V2x communication
An autonomous driving method of a vehicle using V2X communication includes acquiring signal information about a plurality of traffic lights installed at an intersection, determining a signal error in at least one of the plurality of traffic lights by comparing signal information about at least two traffic lights intersecting or facing each other among the acquired signal information, and resetting a driving path of a host vehicle depending on a result of the determination.
DRIVER FEEDBACK FOR EFFICIENTLY TRAVERSING INTERSECTIONS
In a method for efficiently guiding a driver of a vehicle through intersections, information regarding status of one or more traffic lights positioned at one or more intersections is received by a computing device or system associated with the driver or vehicle. A value of speed for the vehicle that, if matched by the driver, causes the vehicle to arrive at the intersection while the traffic light is green and avoids stopping as the vehicle moves through the intersection, is calculated. A dynamic visual or audio indicator is caused, by the computing device or system, to be presented to the driver via a display or speaker, respectively, of the computing device or system. Causing the dynamic indicator to be presented to the driver includes setting the dynamic indicator based on the calculated value of speed.
METHOD, COMPUTER PROGRAM AND APPARATUS FOR CONTROLLING OPERATION OF A VEHICLE EQUIPPED WITH AN AUTOMATED DRIVING FUNCTION
A method, a computer program, and an apparatus for controlling operation of a transportation vehicle equipped with an automated driving function and a transportation vehicle equipped with an automated driving function which uses the method or apparatus. A first signal state of a traffic light is determined from data of at least one vehicle sensor, the determined first signal state of the traffic light is then validated based on information available in the transportation vehicle, and an operation mode of the transportation vehicle is set as a function of a validation result.
