Abstract

An adaptive vehicle collision avoidance system is mounted on a vehicle to provide a collision avoidance reminder when the vehicle is approaching a front object during the movement thereof. The adaptive vehicle collision avoidance system comprises a measurement unit and a control unit. The measurement unit detects an instantaneous distance of the vehicle relative to the front object and a relative speed. The control unit is electrically connected to the measurement unit and has built therein a predetermined safety time, an operation module, and a determination module. The operation module generates a response distance correlated to the relative speed and the safety time. The determination module issues a reminder message when determining the instantaneous distance is not greater than the response distance.

Description

Adaptive vehicle driving collision avoidance system

The invention relates to a vehicle collision avoidance system, in particular to an adaptive vehicle driving collision avoidance system.

In general, when the vehicle is reversing, it usually provides a collision prevention prompt at the rear of the vehicle, so that the user can avoid collision during the operation, and also provides a forward collision prevention prompt on the part of the vehicle, and the prompt condition is to adopt a fixed The minimum safety distance, when the distance between the vehicle and a front object is not greater than the minimum safety distance, a prompt sound is generated. However, the actual speed change is quite large, and the safety distance should be increased as the vehicle speed increases, so the aforementioned minimum safety is adopted. The way of distance is still not effective to avoid the danger of high speed.

Accordingly, it is an object of the present invention to provide an adaptive vehicle driving collision avoidance system that increases frontal collision safety during vehicle travel.

Accordingly, the adaptive vehicle driving collision avoidance system of the present invention is for mounting on a vehicle and providing an anti-collision prompt for approaching a front object during traveling of the vehicle, the adaptive vehicle driving collision avoidance system comprising a measuring unit, And a control unit.

The measuring unit can detect an instantaneous distance and a relative speed of the vehicle relative to the front object.

The control unit is electrically connected to the measuring unit, and has a predetermined safety time, an operation module, and a determination module, and the operation module can generate a reaction distance related to the relative speed and the safety time. The determining module outputs a prompt message when the instantaneous distance is not greater than the reaction distance.

The beneficial effects of the present invention are: considering the relative speed and the mechanism of the safety time through the reaction distance, regardless of the change in the speed of the vehicle, the reaction distance can be matched with the change of the relative speed to generate a sufficient distance length for use. The person has enough time and distance to perform the deceleration, so it can really achieve the effect of effectively avoiding the frontal collision.

The foregoing and other objects, features, and advantages of the invention are set forth in the <RTIgt;

As shown in FIG. 1, a preferred embodiment of the adaptive vehicle anti-collision system 200 of the present invention is for mounting in a vehicle (not shown) and provides an anti-collision approaching a front object 90 during travel of the vehicle. It is suggested that the vehicle refers to a general vehicle in this embodiment. The adaptive vehicle collision avoidance system 200 includes a measuring unit 20, a control unit 30, and a prompting unit 40.

The measuring unit 20 can detect an instantaneous distance d of the vehicle relative to the front object 90 and a relative speed Vr. The measuring technology of the measuring unit 20 can be selected from the group consisting of laser, millimeter wave, microwave, and ultrasonic. .

The control unit 30 is electrically connected to the measuring unit 20 and has a predetermined safety time Tr, a computing module 31, a determining module 32, and a minimum safe distance dm.

The operation module 31 can generate a reaction distance dr related to the relative speed Vr and the safety time Tr. In the embodiment, the reaction distance dr is a product of the relative speed Vr and the safety time Tr (dr=Vr ×Tr).

The determining module 32 outputs a prompt message when the instantaneous distance d is not greater than the reaction distance dr (d≦dr), and further outputs the prompt information when the determining module 32 determines that the instantaneous distance d is not greater than the minimum safe distance dm. Prompt message.

The prompting unit 40 is electrically connected to the control unit 30, and receives the prompt information, which is outputted from the prompting unit 40 in the form of a sound. In the embodiment, the prompting unit 40 uses an independent speaker. The prompting unit 40 can also employ an audio system inside the vehicle.

Thereby, the mechanism of the relative speed Vr and the safety time Tr is considered by the reaction distance dr, and the reaction distance dr can be matched with the change of the relative speed Vr to generate a sufficient distance length regardless of the change in the speed of the vehicle. The user has enough time and distance to perform the deceleration, so it is really effective to avoid the use of frontal collisions.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the present invention and the contents of the specification are all It is still within the scope of the invention patent.
