After step 2, including step 3, the safety distance of the vehicle obstacle in each control scheme is set according to the vehicle speed. When the obstacle is within the non-safe distance, the application processor 22 notifies the sound/light/electricity reminding module 24 to remind the driver. ;

In step 3, the sound/light/electricity reminding module 24 illuminates the warning light by controlling the warning light on the corresponding side of the obstacle to alert the driver or the sound/light/electrical reminder module 24 to broadcast the position of the obstacle by controlling the car audio voice or by the car audio. Alert the sound.

In step 3, the sound/light/electricity reminder module 24 vibrates through the steering wheel, the accelerator pedal when driving at night or when the vehicle continues to travel for a time greater than a threshold for setting the fatigue time or for a predetermined period of time. Vibration, or seat vibration to alert the driver.

The preset speed value between the low speed and the high speed of the vehicle speed is set according to the user requirements or the vehicle speed limit. The driver handles the emergency situation (emergency braking): 0.2-0.4 seconds, and the product of the reaction time and the vehicle speed in the corresponding scheme is the minimum obstacle safety distance. Among them, the range of the blind zone, that is, the effective coverage of the camera, will be obvious to those skilled in the art, and the general definition includes the invisible area of the driver when driving the car. Of course, the driver can see the area, this patent The camera can be covered, and the effective coverage of the camera can reach 30 meters. CPLD: 5M160ZE64C5N; the processor is a product of Altera Corporation. Preferably, the front group camera is arranged in an n-type group at the front of the car; the center camera is installed near the front LOGO of the car, or near the center position of the front bumper; the left front camera is mounted on the left side mirror to illuminate forward, or The left front camera is mounted on the left side of the car near the rear of the car; the right front camera is mounted on the right rear view mirror, or the right front camera is mounted on the right side of the car near the rear of the car; The rear camera is arranged in groups; the rear camera is installed near the rear LOGO of the car, near the rear license plate light, or near the center of the rear bumper; the left rear camera is mounted on the left rear view mirror to illuminate backward; the right rear camera Installed on the right side of the rearview mirror to illuminate backwards. After a large number of road tests, according to the driver's operation of the car signal habits and considering the driving situation of the blind zone auxiliary products, the present invention uses the CAN/manual, left steering, right steering, reverse, brake, and headlight car signals as the control trigger blind zone auxiliary camera single video image. A source that automatically switches to achieve a grouped video image on a split screen or a single screen display on the display. In addition to the blind zone assist and video recording function, the center camera can also extend the lane departure and forward collision warning function; the left/right camera can extend the lane departure in addition to the blind zone assist and video recording functions. Early warning function. In actual use, because the low-speed driving in the crowded roads in the city is the normal state, the driver pays more attention to the blind spot in front of the car. In order to solve the blind spot in front of the car, the left camera is installed in the vicinity of the left side of the car to illuminate forward; the right camera is installed in the vicinity of the right side of the car to illuminate forward. For commercial vehicles driving on expressways, drivers are more concerned about the risk of lane change between overtaking and side lane vehicles, so drivers pay more attention to the rear and side blind areas. In order to solve the risk caused by the lane change of the lane change, the left camera is mounted on the left rearview mirror and the right camera is mounted on the right rearview mirror. In addition, based on the front of the commercial vehicle, the front part of the commercial vehicle is mostly flat. In order to achieve better blind zone auxiliary effect, the left front camera of the commercial vehicle is installed in the vicinity of the left side of the car and the front right camera is installed in the vicinity of the right side of the car. Irradiation. For commercial vehicles with a long front at the front of the car, such as school buses, commercial vehicles, and taxis, the left front camera can be mounted on the left rear view mirror for forward illumination, and the right front camera mounted on the right rear view mirror to illuminate forward; The best solution is that the left front camera is installed in the vicinity of the left side of the car and the front side is illuminated; the right front camera is installed in the vicinity of the right side of the car and the forward illumination is the protection range of the present invention. The invention is derived from the demand analysis of the blind spot problem of the automobile, and has reasonable design, high cost performance, low cost, firm and practical durability, safety and reliability, simple operation, time and labor saving, economy saving, compact structure and convenient use without changing the driver's existing driving habits.
