Abstract

The application discloses a vehicle braking method and device, a vehicle control device and a storage medium, and relates to the technical field of automatic driving. The specific implementation plan is: by obtaining the vehicle condition information of the vehicle; according to the vehicle condition information, determine the configuration parameters of the longitudinal deceleration; according to the configuration parameters, generate the control strategy of the longitudinal deceleration; the control strategy of the longitudinal deceleration includes the first braking stage and the second braking stage In the second braking stage, the longitudinal deceleration in the first braking stage is a constant value, and the longitudinal deceleration in the second braking stage increases; the vehicle braking is controlled according to the control strategy of the longitudinal deceleration. According to the vehicle condition information, the method determines the control strategy of the longitudinal deceleration. By controlling the longitudinal deceleration in the first braking stage, the vehicle decelerates evenly and reduces the inertia during emergency braking. Internal control increases the longitudinal deceleration to make the vehicle decelerate smoothly, thereby ensuring the safety of vehicle braking and improving the body feeling of vehicle braking.

Description

technical field [0001] The present application relates to the technical field of automatic driving in the field of computer technology, and in particular to a vehicle braking method, device and vehicle control equipment. Background technique [0002] Self-driving car, also known as unmanned car, computer-driven car, or wheeled mobile robot, is a kind of intelligent car that realizes unmanned driving through a computer system. The automatic control module of the self-driving vehicle involves the control effect of the whole vehicle, as well as the braking strategy in emergency braking scenarios. [0003] In the emergency braking scene of the existing automatic driving vehicle, when controlling the emergency braking of the vehicle, the maximum braking command is directly sent to the chassis mainly through the control module. However, this braking method produces a large deceleration during the deceleration process, thereby producing a large inertia, which is very easy to cause...
