1, the alarm signal of described siren along with front vehicle and the distance of this spacing and different.When front vehicle farther out time, the threat of this car is little, and when front vehicle is nearer, the modified line of this car is easy for finding scratching with rear car, hence for front vehicle, different alarm signals is set from the distance of this spacing, is conducive to driver to carry out modified line on suitable opportunity.
2, opening and closing under two states at steering indicating light, the alarm signal of described siren is different.When we driver does not have modified line to be intended to, alarm signal should not affect the attention of this car driver excessively strongly；After we driver thinks that steering indicating light is opened in modified line, alarm must provide distinct to driver, be prone to the alarm signal of observation.
3, different and different along with front vehicle and this car relative velocity of the alarm signal of described siren.Sometimes front vehicle is apart from this car farther out, but the speed of front vehicle is very fast, and namely front vehicle is very high with this car relative velocity, then now modified line is easy for scratching；Sometimes front vehicle is relatively near apart from this car, but the speed of front vehicle is far below this car speed, then scratching would not occur in now modified line；It is therefore desirable to the relative velocity for two cars provides different alarm signal to driver, in order to driver judges.
Observe that siren, described siren are the LED being arranged on rearview mirror or A post for ease of driver.
Specifically, described left radar, right radar are microwave radar, are installed in automobile rear bumper, and are fixed on plates of automobile；Left radar is toward the rear, left side of automobile, and right radar is toward the rear, right side of automobile.Rear bumper thickness is advised between 3～4 millimeters, the thickness of rear bumper is not allow for unexpected change, the internal screen without bulk of rear guarantor, at radar and the object such as wire harness, collision prevention girders of having tried not between guarantor afterwards, change if the later stage exists rear bumper profile, then system needs again to demarcate, and radar is from the required distance of rear guarantor more than 6 millimeters, and terrain clearance is between 400～650 millimeters.
The vehicle blind zone detection system of the present invention adopts microwave radar, its detection range is (about 70 meters) farther out, and carry out different warning signals for the different situations of rear car, it is possible to provide reliable, detailed reference for the modified line of driver, be conducive to driver to make correct judgement.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the vehicle blind zone detection system of the present invention.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the effect and operation principle etc. of the mutual alignment between the such as involved shape of each component of the specific embodiment of the present invention, structure, each several part and annexation, each several part is described in further detail.
Embodiment 1:
As shown in the figure, the vehicle blind zone detection system of the present embodiment is made up of controller and the left radar being connected with controller respectively, right radar, siren, vehicle speed sensor, steering indicating light, described controller receives the signal of vehicle speed sensor the work according to the signal left radar of control of vehicle speed sensor, right radar；Controller receives the return path signal of left radar, right radar, and controls the work of siren according to described return path signal.
Specifically, when speed is higher than preset vehicle speed (30Km/h), controller controls left radar, right radar is started working, when other vehicles occurs in the search coverage of left radar, right radar, controller controls siren and reports to the police, to remind driver to note front vehicle.When speed is lower than preset vehicle speed, driver has time enough and response speed to carry out modified line operation, therefore detects the prompting of system without vehicle blind zone, now closing automobile blind area detection system.
