Embodiment Construction

[0130] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0131] Before introducing the embodiments of the present invention in detail, firstly, terms involved in the embodiments of the present invention are explained.

[0132] comfort index

[0133] The comfort index is used to indicate whether the occupant feels comfortable during braking. In the embodiment of the present invention, the comfort index is measured by the maximum braking acceleration parameter. Specifically, the maximum braking acceleration parameter may include the maximum braking acceleration and the maximum braking jerk, that is, the comfort index may be measured by the maximum braking acceleration Acceleration and maximum braking jerk are measured. Correspondingly, the comfort index includes maximum comfortable br...

Abstract

The invention discloses a vehicle braking method, and belongs to the technical field of automobiles. The method comprises the steps that state information of a target vehicle, the distance between thetarget vehicle and a preceding vehicle and the speed of the preceding vehicle are acquired; according to the state information of the target vehicle and the speed of the preceding vehicle, brake dataof the target vehicle with the speed of the preceding vehicle as the target brake speed are determined through a specified neural network model, and the brake data comprise the brake distance; a target braking strategy is selected from a plurality of stored braking strategies according to the brake data, the speed of the preceding vehicle and the distance between the target vehicle and the preceding vehicle; and the target vehicle is made to brake according to the target braking strategy. According to the method, the multiple braking strategies are provided for the vehicle, the appropriate braking strategy is selected for braking according to the specific state of the vehicle, and the braking accuracy and flexibility are improved.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a vehicle braking method, device and storage medium. Background technique [0002] Among various traffic accidents, vehicle rear-end collision is the most frequent traffic accident, accounting for more than 70% of traffic accidents. A vehicle rear-end collision is generally caused by an inappropriate following distance, that is, the relative distance between the vehicle and the vehicle in front is less than the safe distance, resulting in untimely braking. For this reason, it is particularly important to brake in advance according to the relative speed and relative distance between the vehicle and the vehicle in front. [0003] In the related art, a vehicle braking method is provided, which includes: calculating the collision time between the vehicle and the vehicle in front according to the speed of the vehicle, the relative speed between the vehicle and the vehic...
