The specific embodiment
As shown in Figure 1, the embodiment of the invention is as follows based on the implementation step of the vehicle barrier monitoring method of bearing circle vibrations:
1) is provided for sending the obstacle minor increment of prompting;
2) when vehicle operating, detect the obstacle distance nearest apart from vehicle body by range only radar;
3) obstacle distance and the obstacle minor increment that in real time current detection is obtained compares, and when obstacle distance during less than the obstacle minor increment, steering wheel for vehicle applied vibrations to send the approaching prompting of obstacle to chaufeur.
In the step 3) steering wheel for vehicle being applied vibrations specifically is meant: at first obtain the difference of obstacle distance and obstacle minor increment, then according to the size adjustment vibration frequency of difference, and according to this oscillation frequency steering wheel for vehicle is applied vibrations.In the present embodiment during according to the size adjustment vibration frequency of difference, if the difference of obstacle distance and obstacle minor increment diminishes then vibration frequency is increased.The size of oscillation frequency promotes often can for the enough focuses of chaufeur, changes as friction coefficient between velocity variations or the plane of action, and chaufeur consciousness is concentrated.
When obstacle distance is lower than the obstacle minor increment, also comprises simultaneously to chaufeur and send the approaching auditory tone cues of reminding of obstacle in the step 3).When chaufeur sent the auditory tone cues of the approaching prompting of obstacle, the frequency if the difference of obstacle distance and obstacle minor increment diminishes with auditory tone cues increased in the present embodiment.
In the present embodiment, read vehicle backing radar output data by vehicle-mounted computer and obtain the obstacle distance nearest, and obstacle distance information is exported by wireless network apart from vehicle body.The vehicle backing radar is when work, at first obtain the environment obstacle distance, the described information of obtaining is by infrared distance measurement module baseband processor, in order to whether there to be the detecting process of obstacle in each radiation direction in the control detection scope, and according to described phased antenna launched microwave signal and the time difference of accepting reflected signal, cooperate the aerial radiation direction, thereby determine the distance of automobile and obstacle.
