Method and device for acquiring car distance, storage medium and car

Abstract

The invention relates to a method and a device for acquiring a car distance, a storage medium and a car. The method is applied to the target car, and the target car is any one car in multiple automatic drive cars except for a first car. The method comprises the steps of acquiring a first driving parameter of the target car at a target moment; acquiring a second driving parameter of a front car ofthe target car in the multiple automatic drive cars at the target moment; acquiring a first car distance between the target car and each front car at the target moment; and determining a target car distance between the target car and the adjacent front car according to the first driving parameter, the second driving parameter and the first car distance. According to the method and the device for acquiring the car distance, the storage medium and the car provided by the invention, when determining the target car distance, second driving parameters of the all front cars before the target car arecombined, so that the problem that the target car generates response lag on the aspect of car distance control can be avoided, and the car distance between each two adjacent cars in the multiple automatic drive cars can be well controlled.

Description

technical field [0001] The present disclosure relates to the field of vehicle automatic driving, and in particular, relates to a method, device, storage medium and vehicle for obtaining vehicle distance. Background technique [0002] With the development of autonomous driving technology and Internet of Vehicles technology, autonomous driving fleets have been widely used. All vehicles in the self-driving fleet have the ability to drive automatically, and the following vehicles can follow closely in sequence under the leadership of the leading vehicle. [0003] At present, the self-driving fleet adopts the scheme that the vehicle behind follows the vehicle in front. This method can achieve a certain effect of following the vehicle when the team is driving stably, but when the team accelerates and decelerates, there is a lag in the response of the following vehicle in the inter-vehicle distance control. Therefore, the distance between vehicles in the convoy is too long or the ...
