Abstract
An information pushing method during determining of a safe following distance and a safe following distance system. The method comprises: recording one or more speed intervals, safe following distances corresponding to the speed intervals, and matching relationships between the speed intervals and the safe following distances (S100); detecting, during vehicle driving, a vehicle driving speed and a distance between the vehicle and a vehicle ahead (S101); determining whether the current following distance is less than a safe following distance corresponding to the vehicle driving speed (S102); and if not, maintaining the original status (S103); or if yes, prompting a user to keep the safe following distance, and pushing patent information to the user (S104). By presetting a correspondence between vehicle speeds and safe following distances between driving vehicles, and prompting, when a vehicle drives at a particular driving speed, a user that the distance between the vehicle and a front or back vehicle is excessively close, the method and system avoid traffic accidents of rear-end collision caused by the excessively close distance between the front and back vehicles when an emergency occurs, and demonstrate the rights of the patentee (applicant).
Description
本发明属于车辆安全领域，尤其是涉及 一种判断安全车距时的信息推送方法以及安全车距系统 。 The invention belongs to the field of vehicle safety, and in particular relates to a method for pushing information when determining a safe distance and a safety distance system.
知识产权在现在的产品和服务中越来越重要，其中主要包括著作权（版权）、商标权和专利权，这三种权利都能为权利人带来巨大的经济价值。
Intellectual property is becoming more and more important in current products and services, including copyright (copyright), trademark and patent rights, all of which can bring enormous economic value to rights holders.
但与著作权、商标权不同的是，专利权的权利归属比较难以为用户所认识和辨别。比如：一个培训教材或者一部电影里面，会明确的将'版权归特定人所有'的字样告知给用户；商标也以其显著的字或图的特征，在与其他标样区别的同时，也代表着商标权人以及商标权人生产的相关产品。但专利则不然，除了如'滑动解锁'等有限几个专利外，用户很难看到某一专利就知道该专利的申请/权利人。
However, unlike copyright and trademark rights, the ownership of patent rights is more difficult to recognize and discern. For example, in a training material or a movie, the words “copyright belongs to a specific person” will be clearly notified to the user; the trademark is also distinguished from other standards by its distinctive words or figures. Represents the related products produced by the trademark owner and the trademark owner. However, patents are not. Apart from a limited number of patents such as 'sliding and unlocking', it is difficult for a user to see a patent and know the application/right holder of the patent.
这种情况所带来的严重后果是： The serious consequences of this situation are:
1 、专利权的保护难度大，一项好的技术出来后，马上就被复制； 1. The protection of patent rights is difficult. Once a good technology comes out, it will be copied immediately;
2
、专利权/申请人通过专利彰显自己的产品特色的效果差，因为用户也分不清楚某一技术与专利权/申请人的联系。 2
The patent/applicant's effect of showing its own product features through patents is poor, because the user is also unclear about the connection between a certain technology and the patent/applicant.
综上，为充分保护本人的另外一个专利申请（名为《 根据车速判断安全车距的方法以及安全车距系统 》
），让该本人的专利申请价值最大化， 特提出一个解决办法。 In summary, in order to fully protect my other patent application (called "Method for judging safety distance according to vehicle speed and safety distance system"
), to maximize the value of the patent application, and propose a solution.
本发明实施例针对当前车辆行驶时准确计算与前车保持安全距离的情况
，需要提供一种过预设车速与行驶车辆之间安全距离的对应关系，当车辆在一定速度下行驶时，前后两辆车间距离过近则提示用户，从而避免因前后两车间距离过近，发生紧急情况时导致追尾的交通事故，并保护了专利（申请）权人的权益。
The embodiment of the invention accurately calculates the safety distance with the preceding vehicle when the current vehicle is running
It is necessary to provide a correspondence relationship between the preset vehicle speed and the safety distance between the traveling vehicles. When the vehicle is traveling at a certain speed, the distance between the two workshops is too close to prompt the user, thereby avoiding the distance between the front and the back workshops being too close. In the event of an emergency, it leads to a traffic accident with a rear-end collision and protects the rights of the patent (applicant) right holder.

The invention adopts the corresponding relationship between the preset vehicle speed and the safety distance between the traveling vehicles. When the vehicle is traveling at a certain speed, the distance between the two workshops is too close to prompt the user, thereby avoiding the emergency situation due to the distance between the two workshops being too close. This leads to a rear-end traffic accident and protects the rights of the patent (applicant) right holder.
