Description
Technical field
The application belongs to Vehicle lighting field of intelligent control, particularly relates to a kind of intelligent automotive light control based on OBD interface
System processed.
Background technology
AUTHORITATIVE DATA shows, the vehicle accident of 60% occurred at night, and 22% occurs the situation in bad weather, only 18%
Occur on light good daytime.Therefore, vehicle light illumination is closely related with traffic safety.On the one hand, the car light of light distribution effect difference
The lighting requirement of the complex road conditions such as abrupt slope, sharp turn cannot be met；On the other hand, in running at high speed, human eye is in the shape of constant tension
State, bad illuminating effect easily causes Driver Vision tired, thus causes the generation of vehicle accident.But great majority are driven
For the person of sailing, car light controls to be still limited to light or extinguish, the most also cannot be according to outside concrete environment and reality
Time traffic information realize the intelligentized control method of vehicle light illumination pattern.
At present the technical scheme about intelligent automotive light substantially can be divided into two categories below:
(1) by installing related sensor collection running information at automobile external, car light is controlled further according to relevant information
Follow-up steering, it is achieved the intelligentized control method of car light.As Chinese patent application 201510148964.5 discloses a kind of modularity
Autonomous type car headlamp follower steering device, this device includes car light and drives the motor of car light action, in device
It is additionally provided with gyroscope and the acceleration sensor of sensing vehicle acceleration information of sensing vehicle heading.
(2) based on network technology, the real-time running information that electrical control unit unit (ECU) is internal is read, further according to row
Car data information, it is achieved the intelligentized control method of car light.As Chinese patent application the 200810151503.3rd disclose a kind of based on
The adaptive front lighting lamp system control system of network technology and control method thereof, the AFS controller in this system by CAN/LIN with

External gyroscope and acceleration sensor in lamp, on the one hand add cost；On the other hand also increase installation difficulty, reduce and be
The practicality of system.And the running information that outer sensor records is for actual travelling data, there is certain mistake
Difference.In scheme (2), AFS controller can only read the heat transfer agent of vehicle body by specific a kind of agreement, and this kind of mode can only pin
To specific vehicle, it is not suitable for using the vehicle of other bus protocols.It addition, this system can only read direction dish corner, speed
Running information simple with suspension height etc., for vehicle body lists such as navigator fix, change speed gear box and engine management systems (EMS)
The control information of unit all cannot read.
OBD interface is the external interface of vehicle self-carrying, and it is a part for vehicle-mounted self-diagnosis system.At car running process
In, vehicle-mounted self-diagnosis module can monitor the operation conditions of vehicle body electric-control system and related circuit in real time.Although automobile OBD goes out
It is now to facilitate the maintenance of vehicle to obtain the DTC of automobile, but excellent by its uniqueness in terms of vehicular data acquisition
Gesture can carry out systematized scanning (including navigation system, automobile dynamic system, body control system etc.) to automobile, from
And obtain various valuable information in driving conditions.Such as: the speed in vehicle a certain moment, acceleration, steering wheel angle, position
Put.Therefore, application interface related with OBD is far beyond the category of fault detect.
