    摘要: Disclosed is a method for cooperative decision-making on lane-changing behavior of an autonomous vehicle based on Bayesian game. On one hand, intelligent networked road perception and big data analysis are utilized to infer statistical characteristics of driving styles of a side vehicle under different time periods and traffic flow states, serving as prior predictions of driving styles of the side vehicle. On the other hand, the dynamic interaction behaviors during lane-changing processes of a specified vehicle and the side vehicle are continuously observed and posterior corrections are made to the driving styles of the side vehicle. When the specified vehicle generates a lane-changing willingness, probabilities of driving styles are iteratively predicted using Bayesian game principles. Comprehensive consideration of style and willingness probabilities yields a lane-changing probability of the specified vehicle. Once the lane-changing probability exceeds a threshold, a lane-changing activation instruction is issued.

    摘要: An autonomous driving system includes a vehicle detection device for detecting surrounding vehicles present in surroundings of a host vehicle, a display device for displaying the surrounding vehicles detected by the vehicle detection device as vehicle icons, and a processor configured to control display content of the display device, control autonomous driving of the host vehicle, and set a vehicle necessitating deceleration from among the surrounding vehicles detected by the vehicle detection device. The processor is configured to control acceleration and deceleration of the host vehicle so that the host vehicle does not approach the vehicle necessitating deceleration, and when a plurality of surrounding vehicles detected by the vehicle detection device are displayed on the display device, the processor is configured to display a vehicle icon of the vehicle necessitating deceleration in a display mode different from vehicle icons of remaining surrounding vehicles.

    摘要: A vehicle driving assistance apparatus terminates decelerating an own vehicle with a second deceleration characteristic by a deceleration control and starts to decelerate the own vehicle with a first deceleration characteristic by the deceleration control when a predetermined time elapses since an accelerator operation is released while a deceleration target is detected, or when a deceleration intensity of the first deceleration characteristic is equal to or smaller than a predetermined intensity. The apparatus terminates decelerating the own vehicle with a third deceleration characteristic by the deceleration control and starts to decelerate the own vehicle with the first deceleration characteristic by the deceleration control when a predetermined time elapses since a brake operation is released while the deceleration target is detected, or when the deceleration intensity of the third deceleration characteristic is equal to or smaller than a predetermined intensity.

    摘要: A vehicle control device includes a processor. The processor is configured to receive a first requested value of acceleration acting on a vehicle from a first system configured to request holding a stopped state of the vehicle. The processor is configured to receive a second requested value of the acceleration from a second system. The processor is configured to select one of the first requested value and the second requested value as an arbitration result. The processor is configured to set a priority for selecting the first requested value lower than a priority for selecting the second requested value when the processor acquires predetermined information from one of the first system and the second system while the vehicle is stopped.
