Description of the drawings
Fig. 1 is the annexation figure of the utility model.
Specific implementation mode
The utility model is further illustrated in the following with reference to the drawings and specific embodiments.
Embodiment
In conjunction with Fig. 1, elaborate to the present embodiment.A kind of advanced driving assistance system involved by the present embodiment, packet
Vehicle CAN bus, middle control instrument, stacked switch, vehicle control device, preceding millimetre-wave radar, the other camera of forward sight, blind area are included from thunder
Reach, blind area main radar, panoramic looking-around system and auxiliary automated parking system.
Middle control instrument, stacked switch, vehicle control device, preceding millimetre-wave radar, the other camera of forward sight, blind area are from radar and auxiliary
It helps automated parking system to be connected with CAN bus, directly sends control signals in CAN bus, and by corresponding subsystem
Received by itself, the control signal or alarm signal that subsystem is returned also are sent directly in CAN bus, are held by actuator reception
Row, such setting largely simplify control logic.Preceding millimetre-wave radar is millimeter wave thunder before 77GHz in the present embodiment
It reaches.
Millimetre-wave radar is connect with the other camera of forward sight by the first privately owned CAN before 77GHz, for millimeter wave before 77GHz
The data communication that sensor between radar and the other camera of forward sight is integrated, such setting can reduce the bandwidth of vehicle CAN bus
Consumption.
Blind area is connect by the second privately owned CAN with blind area main radar from radar, is used for data transmission between the two.And only
By being connected from blind area radar with vehicle CAN bus, blind area main radar is not connected with vehicle CAN bus, and such setting is not
It is only capable of reducing the bandwidth consumption of vehicle CAN bus, moreover it is possible to reduce the number of nodes of vehicle CAN bus.In the present embodiment blind area from
Radar is the blind areas 24GHz from radar, and blind area main radar is the blind areas 24GHz main radar.
The blind areas 24GHz main radar is connected with left-hand mirror warning light, directly drives left-hand mirror warning light；The blind areas 24GHz
It is connected with right rear view mirror warning light from radar, directly drives left and right rearview mirror warning light.Such type of drive is simple, and use is left back
Visor warning light and right rear view mirror warning light do not have to be directly accessed vehicle CAN bus, reduce fractional hardware cost.
Auxiliary automated parking system is connected by the privately owned CAN of third with panoramic looking-around system, and biography between the two is used for
The data communication that sensor is integrated, can reduce the bandwidth consumption of vehicle CAN.Auxiliary automated parking system is connected with 12 super waves and passes
Sensor, for super wave sensor 1, super wave sensor 2 to super wave sensor 12.Panoramic looking-around system be connected with preceding camera, after take the photograph
As head, left camera and right camera.
Panoramic looking-around system is connected by Ethernet with display equipment.Ethernet has bandwidth height, but agreement is complicated,
Real-time is poor.Using a bit can be by the panoramic looking-around not high to requirement of real-time（AVM）System access Ethernet, passes through Ethernet
Image data is sent to display equipment, to meet the transmission demand of high-resolution video, while being not take up the money of CAN bus
Source.
Advanced driving assistance system main body involved by the utility model is communicated using CAN bus, simplifies system
Structure so that whole system is clear in structure, provides better scalability for system, and be convenient for fault diagnosis and repair.
Flexibly using data communication between privately owned CAN connections subsystem progress subsystem, reduce the bandwidth consumption of vehicle CAN.Directly drive
Dynamic part warning light, reduces hardware cost.Using Ethernet, meets the needs of high definition video data transmission.
