Abstract
Description
本發明是有關於一種車用安全警示系統，特別是有關於一種具有警示後方尾隨車輛功能之車用安全警示系統。 The invention relates to a vehicle safety warning system, in particular to a vehicle safety warning system with a warning tail trailing vehicle function.
汽車於公路駕駛時，常會碰到大型車輛未保持安全距離，緊貼近於小型車後側，其目的或可能是為了要逼前方小型車讓開車道，而若於車流不擁塞的情況下，小型車多採避讓的方式更換車道，以減去後方車輛距離太近的壓力，但是當道路車輛擁塞，卻又遇上後方車輛近距離尾隨，在此壓力下而被迫變換車道，或是必須分心注意後方車輛，對於整個行車安全性是相當大的威脅。 When a car is driving on a highway, it often encounters a large vehicle that does not maintain a safe distance and is close to the rear side of the small car. The purpose may be to force the small car in front to open the lane, and if the traffic is not congested, the small car is more The lane is replaced by the way of avoiding, so as to reduce the pressure of the rear vehicle too close, but when the road vehicle is congested, but the rear vehicle is closely followed, it is forced to change lanes under this pressure, or must be distracted. Rear vehicles are a considerable threat to overall driving safety.
而目前車輛的主動安全警示系統，絕大部分都是以車子前方之狀況作為發展主軸，車頭前方裝設雷達以偵測與前車的車距，當車輛與前車間距過小，或接近速度太快時，系統就會發出警示，若經系統判斷出有碰撞危險，系統還會經由自動計算，透過剎車輔助系統，提供最理想的剎車輔助力道，使駕駛即使在踩剎車踏板的力道不足的情況下，也能補足避免碰撞發生所需的剎車力道，但如此設計仍無法完全滿足駕駛者的安全防護。 At present, most of the active safety warning systems of vehicles are based on the situation in front of the car as a development spindle. The radar is installed in front of the front of the vehicle to detect the distance from the preceding vehicle. When the distance between the vehicle and the preceding vehicle is too small, or the speed is too close. When it is fast, the system will issue a warning. If the system determines that there is a danger of collision, the system will automatically calculate and provide the optimal brake assisting force through the brake assist system, so that the driving force is insufficient even when the brake pedal is pressed. Underneath, it can also make up the braking force needed to avoid collisions, but the design still can not fully meet the driver's safety protection.
因此，近年來漸有關於車後安全防護的系統被發展及重視，最為普及使用的是倒車雷達系統，在低速倒車行駛的狀況下，可以藉由雷達等測距裝置，判斷與後方車輛的距離，若車距過近，則發出警示，但此一設計僅能於低速行駛時使用，且其所提供之警示多以蜂鳴警報器為之，若採用此一系統作為防追撞的方式，則當後車車距過近時即對駕駛者發出一蜂鳴警報聲，惟如此對駕駛人在後方車逼近的壓力下，更因蜂鳴警報警示造成更大壓力，更威脅駕駛人的行車安全，此外，目前追撞車禍發生後之肇事主因多半不易釐清，亦常常讓責任之歸究上產生重重困難，無法掌握現場之事實真相更可能讓裁定不公，此亦為當前交通問題裡最難以解決的一個環節。 Therefore, in recent years, systems for post-vehicle safety protection have been developed and valued. The most popular use is the reversing radar system. In the case of low-speed reversing, the distance between the vehicle and the rear vehicle can be judged by a distance measuring device such as radar. If the distance between the cars is too close, the warning will be issued, but this design can only be used at low speeds, and the warnings provided by them are mostly based on buzzer alarms. If this system is used as an anti-collision method, Then, when the distance between the rear and the rear of the vehicle is too close, the driver will beep. However, under the pressure of the driver approaching the rear car, the buzzer alarm will cause more pressure and threaten the driver’s driving. Safety, in addition, the main cause of the accident after the current car accident is difficult to clarify, and often causes difficulties in the investigation of responsibility. The fact that the situation cannot be grasped is more likely to make the decision unfair, which is the most difficult in current traffic problems. A link to solve.
因此，如何有效避免後車未保持安全距離及故意跟車之行為，造成行車之危險性，實為急需解決的問題。 Therefore, how to effectively prevent the rear car from maintaining a safe distance and deliberately following the behavior of the car, resulting in the danger of driving, is an urgent problem to be solved.
有鑑於上述習知之問題，本發明之一目的就是在提供一種車用安全警示系統，提供一主動警示予尾隨車輛，以解決習知於公路駕駛時，尾隨車輛跟車過近對駕駛人行車安全之威脅。 In view of the above-mentioned problems, it is an object of the present invention to provide a vehicle safety warning system that provides an active warning to a trailing vehicle to solve the problem that when a road vehicle is driven, the trailing vehicle is too close to the driver to drive safely.
