Abstract

The application discloses a vehicle braking method and device, vehicle control equipment and a storage medium, and relates to the technical field of automatic driving. According to the specific implementation scheme, vehicle condition information of a vehicle is obtained; configuration parameters of a longitudinal deceleration are determined according to the vehicle condition information; a control strategy of the longitudinal deceleration is generated according to the configuration parameters, wherein the control strategy of the longitudinal deceleration comprises a first braking stage and asecond braking stage, the longitudinal deceleration in the first braking stage is a constant value, and the longitudinal deceleration in the second braking stage is increased progressively; and the vehicle is controlled to brake according to the control strategy of the longitudinal deceleration. According to the method, the control strategy of longitudinal deceleration is determined based on the vehicle condition information, the longitudinal deceleration is controlled to be unchanged in the first braking stage, so that the vehicle is uniformly decelerated, and the inertia during emergency braking is reduced; and the longitudinal deceleration is controlled to be increased progressively in the second braking stage, so that the vehicle is stably braked and decelerated. Therefore, the brakingsafety of the vehicle is ensured, and the braking somatosensory feeling of the vehicle is improved.

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...
