Embodiment Construction
[0010] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0011] figure 1 The scene near the expressway exit to which the present invention is applicable is depicted by way of example, including multiple traffic participants, for example, the vehicle E and its surrounding vehicles. The own vehicle E is driving on the own lane L2, on the own lane L2, the front vehicle F is driving in front of the own vehicle E, and the rear vehicle R is driving behind the own vehicle E. The expressway exit is located on the first adjacent lane L1 adjacent to one side (eg, adjacent to the right side) of the own lane L2. The neighboring vehicle A is driving on the second adjacent lane L3 adjacent to the other side (for example, adjacent to the left side) of the current lane L2. Both the vehicle E and the adjacent vehicle A are relatively close to the expressway exit in the longitudinal direction. Neighboring car A inten...

The invention provides a control unit, method and system for highway driving assistance. The control unit comprises: an acquisition module configured to acquire an image containing a road sign of a first adjacent lane, driving data of an adjacent vehicle on a second adjacent lane, and driving data of the vehicle; an judgment module configured to judge whether an expressway exit appears on a first adjacent lane based on the image, and judge whether the adjacent vehicle has a lane changing trend of changing to the lane based on the driving data of the adjacent vehicle if the expressway exit appears on the first adjacent lane; and a calculation module configured to take the adjacent vehicle as the front vehicle of the vehicle under the condition that the judgment module judges that the lane changing trend exists, and calculate the deceleration of the vehicle based on the longitudinal vehicle speed of the adjacent vehicle, the longitudinal vehicle speed of the vehicle, the longitudinal relative distance between the vehicle and the adjacent vehicle and the safety distance of the vehicle.
Description
technical field [0001] The present invention relates to the technical field of highway driving assistance, in particular to a control unit, method and system for high-speed driving assistance. Background technique [0002] The probability of a traffic accident on the road is higher than that of the expressway. On the expressway, near the exit of the ramp is an accident-prone area. Although it is known that there are many driving assistance schemes that can reduce the risk of traffic accidents, there is no technology that can effectively prevent the collision caused by vehicles changing lanes near the exit of the expressway. Program. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the present invention provides a technical solution for highway driving assistance, which can prevent collision accidents near highway exits. [0004] To this end, the present invention provides the technical solutions according to the claims. [00...
