Embodiment
Method and apparatus with specific embodiment to the switch steering indicating light provided by the invention based on OBD below in conjunction with the accompanying drawings
It is described in detail.
According to an aspect of the invention, it is proposed that the method for the switch steering indicating light based on OBD, as shown in figure 1, including：Step
1：Obtain speed and steering wheel angle；Step 2：Calculate actual vehicle speed and steering wheel actual rotational angle；Step 3：According to presetting
First threshold, judge whether vehicle is in turn condition, if vehicle is in turn condition, open steering indicating light；According to advance
The Second Threshold of setting, judges whether vehicle is in lane change state, if vehicle is in lane change state, opens steering indicating light.
Specifically described with reference to embodiment.
1. obtain OBD data, calculate actual vehicle speed and corner.
When opening ignition switch, device brings into operation, and receives speed bus data and steering wheel angle bus data, according to
Pre-prepd algorithm calculates actual vehicle speed and steering wheel actual rotational angle.
(1) method for obtaining steering wheel angle is as follows：
From OBD obtain data be：302 0D 67 17 18 34 0F 40 31
302 represent ID heads, behind since the 0th byte, be followed successively by 0D, 67,17 etc..Wherein second and third byte side of containing
To the data of disk corner, i.e., 1718.When steering wheel is placed in the middle, second and third byte is 0x1770, and this interval scale steering wheel angle is
0；Second and third byte is more than 0x1770 when beating steering wheel to the right, and now (second and third byte -0x1770) is converted to decimal number
Value is exactly to beat the angle of steering wheel to the right；When beating steering wheel to the left, second and third byte is less than 0x1770, and now (0x1770 is subtracted
Second and third byte) decimal value be the angle for beating steering wheel to the left.
Second and third byte is 0x1718 in this data, that is, is turned left, steering angle be (0x1770-0x1718)=
0x58, it is 88 after the decimal system, i.e., has beaten 88 ° of steering wheel to the left.
(2) method for obtaining speed is as follows：
The data obtained from OBD are as follows：300 03 1C 08 00 00 00 00 00
The decimal value of wherein the first byte is exactly specific speed.Speed is 0x1C=28km/h in this data.
(3) actual vehicle speed and tire actual rotational angle are calculated
Steering wheel angle and tire corner ratio are assumed to be C, steering wheel angle A, then tire actual rotational angle B=A/C.One
As C=8:1, to be determined according to actual vehicle.Calculation formula is：
Tire actual rotational angle=the ratio between steering wheel actual rotational angle/steering wheel angle and tire corner
Actual vehicle speed is exactly the speed obtained.
2. judging turning or lane change, steering indicating light is closed
By comparing actual vehicle speed, tire actual rotational angle and first threshold, judge whether vehicle turns, if turning then
Open steering indicating light.
By comparing actual vehicle speed, tire actual rotational angle and Second Threshold, judge vehicle whether lane change, if lane change is then
Open steering indicating light.
First threshold be speed in 0-40km/h, tire actual rotational angle is more than 30 °.Actual vehicle speed and tire actual rotational angle
During more than threshold value, it is judged to turning.Road surface is narrower and the angle at crossing is smaller, and tire actual rotational angle is bigger.In view of enter it is curved it
Steering wheel rear of setting right is not returned just yet afterwards, thus steering wheel set right after postpone 3s and close steering indicating light.
Second Threshold is that speed is more than 20km/h, and tire actual rotational angle is more than 5 °.Actual vehicle speed and tire actual rotational angle surpass
It is lane change to cross threshold determination.In view of steering wheel rear of setting right still slightly tilts after taking part in Taoism, thus steering wheel set right after postpone
1s closes steering indicating light.
Steering wheel sets right, i.e., steering wheel actual rotational angle is 0.
Also to continue real-time judgment after opening steering indicating light, opening state is always maintained at steering indicating light during lane change to ensure to turn
State and completion are turned, close steering indicating light after lane change.
Real-time reception OBD data are calculated and judged, you can automatically open up and close steering indicating light.
According to another aspect of the present invention, there is provided the device of the switch steering indicating light based on OBD, as shown in Fig. 2 including：
Power module, it is connected with vehicle OBD interfaces, vehicle OBD interface voltages is converted into OBD communication modules and data processing module institute
The voltage needed；OBD communication modules, it is connected with vehicle OBD interfaces, for pickup vehicle data, number is sent to after having collected data
According to processing module；The switch steering indicating light order that data processing module is sent is received, and passes through vehicle OBD interface switch steering indicating lights；
Data processing module, it is connected, the data that analysis OBD communication modules are sent, is controlled by OBD communication modules with OBD communication modules
The on and off of steering indicating light.
Wherein, power module is powered by vehicle OBD interfaces using small storage battery, low in energy consumption, is powered without having to worry about to vehicle
Impact.Car OBD interface is 12V, and OBD communication modules and microprocessor are converted into by the reduction voltage circuit inside power module
3.3V voltages needed for device module.
Data processing module is judged and handled using specific method described above.
The present invention is without the wiring of complexity, and without the external equipment of complexity, required is only connection OBD box, right
Pick up a socket to can be used, the simple easy to get started of device not only improves stability and reaction speed, more avoids because of high temperature
The safety problem triggered with aging circuit problem caused by weathering.
