However, there are always some drivers who do not obey the traffic rules, which may easily cause traffic accidents
[0003] In related technologies, driving safety can be improved by adding safety modules of the vehicle, such as adaptive cruise control (ACC (Adaptive Cruise Control) and automatic emergency braking (AEB) (Autonomous Emergency Braking). Collisions caused by driver misoperation, driving safety still has potential safety hazards

Embodiment Construction
[0030] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0031] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0032] figure 1 It is a flowchart of a driving assistance method for safe driving according to an embodiment of the present invention. Such as figure 1 As shown, the driving assistance method for safe driving according to an embodiment of the present invention includes the following steps:
[0033] S101: Detect the vehicle speed and the distance between the vehicle and the obstacle after the driving assistance function is activated.
[0034] Among them, the speed of the vehicle can be detected by the speed sensor, or converted according to the wheel speed, etc., of course, such as Figure 4 As shown, in the vehicle, it can also be obtained through the feedback of the electronic stabi...

The invention provides a safe driving assisting method and system and a vehicle. The method comprises the following steps that the vehicle speed and the distance between the vehicle and an obstacle are detected after the driving assistance function is started; when the distance between the vehicle and the obstacle is smaller than the sum of the safe redundant distance and the minimum brake distance corresponding to the vehicle speed, the driving assistance function is used for intervention, and the automatic braking of the vehicle is controlled by the maximum brake acceleration; if the distance between the vehicle and the obstacle is larger than the sum of the safe redundant distance and the minimum brake distance corresponding to the vehicle speed, the intervention mode of the driving assistance function is further determined according to the action of a driver; and the vehicle speed is intervened according to the determined intervention mode so as to prevent the vehicle from colliding with the obstacle. According to the method, traffic accidents caused by the fact that the vehicle speed is too high due to misoperation of a driver and the like can be prevented, and the driving safety is effectively improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a safe driving assistance method, system and vehicle. Background technique [0002] With more and more vehicles, the probability of traffic accidents is also increasing, which seriously threatens personal safety. Therefore, in order to improve driving safety, the best preventive measures are to obey the traffic rules, slow down, and avoid hurting others. and cause harm to oneself. However, there are always some drivers who do not obey the traffic rules and easily cause traffic accidents. [0003] In related technologies, driving safety can be improved by adding safety modules of the vehicle, such as Adaptive Cruise Control (ACC) and Automatic Emergency Braking (AEB). If there is a collision caused by driver misoperation, there are still potential safety hazards in driving safety. Contents of the invention [0004] In view of this, the present invention aims to propose a ...
