Method and device for controlling vehicle braking and vehicle

Abstract

The invention relates to a method and a device for controlling vehicle braking and a vehicle, and the method comprises the steps: obtaining the collision type of a current vehicle after the current vehicle is collided; acquiring driving information of the current vehicle according to the collision type; determining whether the current vehicle is in a safe state according to the driving information; under the condition that it is determined that the current vehicle is in the safe state, obtaining driving parameter information of the current vehicle, determining the consciousness state of the driver according to the driving parameter information, wherein the consciousness state comprises a non-intelligence state and an intelligence state; and under the condition that the consciousness stateis determined to be a non-intelligent state, controlling the current vehicle to brake. According to the method, the influence of the driving information of the current vehicle and the consciousness state of the driver on secondary collision after collision can be comprehensively considered, and the problem that beneficial subjective risk avoiding operation implemented by the driver is shielded canbe avoided, so that secondary collision can be flexibly and effectively avoided, and damage of collision to the vehicle is relieved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular, to a method, device and vehicle for controlling braking of a vehicle. Background technique [0002] Generally, in order to improve the safety performance of the vehicle and avoid the secondary collision after the primary collision, the vehicle is usually equipped with a secondary collision mitigation function to avoid the secondary collision or alleviate the damage caused by the secondary collision. [0003] The current secondary collision mitigation function usually shields the driver's driving operation after a collision, that is, directly controls the vehicle to stop without considering the impact of the driver's active intervention on collision mitigation. However, in many collision conditions, Direct braking is not conducive to reducing the damage to the vehicle caused by the collision, and because the current secondary collision mitigation function will shield the d...

Problems solved by technology

[0003] The current secondary collision mitigation function usually shields the driver's driving operation after a collision, that is, directly controls the vehicle to stop without considering the impact of the driver's active intervention on collision mitigation. However, in many collision conditions, Direct braking is not conducive to reducing the damage to the vehicle caused by the collision, and because the current secondary collision mitigation function will shield the driver's active intervention to alleviate the secondary collision after the collision is determined, some drivers with rich experience The driver's subjective risk avoidance operation cannot be finally reflected in the vehicle's risk avoidance process, and the subjective risk avoidance operation cannot play a corresponding role in the process of avoiding secondary collisions.

That is to say, the current secondary collision mitigation function cannot alleviate the damage caused by the collision to the greatest extent, nor can it make beneficial subjective hedging operations play a corresponding role in avoiding secondary collisions.
