1. A method for determining a following relationship of a vehicle and adjusting behavior of the vehicle is characterized by comprising the following steps:

  • step 1;

    calculating a critical value L for judging the car-following relation under the current tracking running state according to the braking mode adopted under the current technical condition in the dynamic transportation environmentAbsolute_BoundaryOr LRelative_BoundaryWherein;

    l isAbsolute_BoundaryIs a critical value of the following relation under the absolute braking mode, and is a critical value L for judging the following relation of the front vehicle and the rear vehicle under the current tracking running state calculated according to the absolute braking mode of the vehicle and by taking the vehicle performance as a constraint conditionAbsolute_Boundary

    LRelative_BoundaryIs a critical value of the following relation under a relative braking mode, and is a critical value L for judging the following relation of the front vehicle and the rear vehicle under the current tracking running state, which is calculated according to the relative braking mode of the vehicles, by taking the vehicle performance as a constraint condition and considering the worst following situationRelative_Boundary

    In the step 1, a method for calculating a car following relation in an absolute braking mode is shown in the following formula (1)
