Problems solved by technology

For example, the target vehicle turns on the left turn signal due to misoperation but has no intention of changing lanes
Moreover, the solutions in the prior art still have the problem that the lane-changing behavior of the target vehicle cannot be judged in time.

Embodiment Construction

[0029] Some feasible implementation manners of the present application are described below with reference to the accompanying drawings.

[0030] The present application generally relates to a driving assistance technology, which is used to provide the host vehicle with lane-changing status information of a target vehicle.

[0031] figure 1 A driving assistance system 100 according to a possible embodiment of the present application is schematically shown. The driving assistance system 100 is arranged on a vehicle, and includes a measurement device 110 and a decision device 120 .

[0032] In this embodiment, the measurement device 110 is used to measure the running state of the own vehicle and surrounding vehicles. Measuring device 110 may include a radar device 130 and a recording device 140 . The radar device 130 is used to detect the position and driving speed (including longitudinal speed and lateral speed) of surrounding vehicles. The photographing device 140 is used ...

Abstract

The present application proposes a lane change determination unit for use in a driving assistance system, comprising: an acquisition module configured to acquire information including driving states of a host vehicle and surrounding vehicles thereof; a processing module which is configured to determine the lane passing efficiency of each lane according to the information acquired by the acquisition module, and calculate and evaluate the driving emotion of the surrounding target vehicles based on the acquired driving state of the surrounding target vehicles; the processing module is further configured to determine a first lane changing probability value of the target vehicle according to the lane passing efficiency and the driving emotion of the target vehicle; and a generation module configured to generate a lane change intention signal indicating a lane change intention of the target vehicle according to the first lane change probability value so as to assist driving of the vehicle.

Description

technical field [0001] The present application relates to the technical field of driving assistance, in particular to a driving assistance system, a lane change determination unit and a lane change determination method thereof. Background technique [0002] With the rapid development of the automobile industry, driver assistance systems representing advanced automobile technologies are more and more commonly used in vehicles. The driving assistance system uses various sensors installed on the car to sense the driving state of the car and the surrounding vehicles during the driving process, and calculate and analyze the sensed data to obtain information that is helpful for driving, so as to realize assisted driving. [0003] The assisted driving system has many functions, which can realize assisted driving from many aspects. Among them, it is a beneficial function to provide the vehicle with the lane change information of the target vehicle, so that the vehicle can make a s...
