To provide a preceding vehicle determination system and a preceding vehicle determination method which can improve the determination accuracy of the preceding vehicle, considering an estimation error of the traveling lane of the own vehicle. A preceding vehicle determination system and a preceding vehicle determination method estimates a high probability region which is a region where the own vehicle probably travels and estimates a middle probability region which is a region where a possibility that the own vehicle travels is lower than the high probability region, based on the traveling state of the own vehicle; and determines whether the front vehicle is a which is traveling forward in a traveling lane of the own vehicle, based on the position history of the front vehicle, the high probability region, and the middle probability region.

The present disclosure provides a device and method for generating lane information. The method includes obtaining information on a structure located around a vehicle and driving information of a surround vehicle based on information collected by a sensor and prestored navigation information; and generating geometric information on a travel lane of the vehicle in a road area based on the information on the structure and the driving information of the surround vehicle.

A method for improving the ride comfort of a transportation vehicle including planning a first driving route by a navigation system; automatically detecting at least one road parameter of the first driving route by a sensor system of the transportation vehicle; automatically evaluating the first driving route in view of the ride comfort of the first driving route by taking into account the road parameter; and in response thereto using the first driving route or planning an alternative driving route.

A method and a control device for controlling speed of a vehicle having an automatic cruise control system configured to automatically control speed based on a set speed and to automatically reduce the speed to a predetermined safe speed below the set speed as it is detected that the vehicle approaches a road section of a predetermined type such as a curve. The method includes while automatically controlling the speed towards the predetermined safe speed as the vehicle approaches the road section of the predetermined type, receiving a request from a driver of the vehicle to control speed to a temporary speed different from the predetermined safe speed and the set speed. The method includes in response to said request, controlling the speed to the temporary speed. The method includes at an end of the road section of the predetermined type, automatically controlling the speed based on the set speed.

A method of controlling operation of a vehicle includes monitoring one or more features of a road segment, the vehicle configured to communicate with a plurality of objects in a wireless communication network, the vehicle configured to generate a communication based on a reference value of a parameter related to at least one of an environment around the vehicle and a behavior of the vehicle. The method also includes determining, based on the monitoring, a condition of the road segment, the condition including at least a curvature of the road segment, inputting the condition into a machine learning model configured to adjust the reference value based on the condition and output an adjusted reference value, and comparing the adjusted reference value to a current parameter value, and based on the adjusted reference value matching the current parameter value, transmitting an alert to one or more of the plurality of objects.

The present disclosure provides a method for generating road topology information performed by at least one processor. With respect to coordinate data of a road, boundary conditions between segments including topology information may be calculated to make the connection between segments flexible, and a midpoint of a curve of a segment may be detected to directly calculate control points of a Bézier curve, thereby generating a parametric Bézier curve. Accordingly, more precise road map may be generated even when the coordinate data of the segment of the road includes an error.
