The manner in which the processing unit 14 controls the direction light 31 or 32 is mainly to supply a high/low pulse (Hlgh/L〇W Pulse) to the transistor ι23 or m. For example, if the steering wheel 21 # is right, the processing unit 14 supplies The high/low pulse is applied to the second transistor m. After the transistor 124 is controlled to be turned on by the processing unit 14, the backup relay 122 can drive the right direction light 32 to turn on and off after the transistors 124 are turned on, that is, automatically The effect of the light warning. In addition, the processing unit 14 corrects the sensitivity of the acceleration detecting unit 1 according to the speed of the vehicle. For example, when the speed of the vehicle is faster, the acceleration detecting unit ίο detects the sensitivity of the angle, so that the steering wheel 21 is turned at an angle. Even if it is very small, the directional light 31 or 32 will automatically generate a clear warning signal 'to avoid the danger that the vehicle can change lanes arbitrarily when driving at high speed; conversely, when the vehicle is moving slowly, it may only be for parking. When the steering wheel 21 is turned, the acceleration_single & 1 is lowered (the sensitivity of the M-measurement angle is lowered, and the angle at which the steering wheel 21 is rotated is required to be large, so that the direction light 3 or 32 automatically generates a light-off warning. 10 12936〇6 At the same time, the processing unit 14 also issues a signal control alarm unit 16 to generate an alarm sound, which is controlled by the processing unit Μ providing a variable frequency clutter width ～ (PWM) signal to the transistor 164, thereby starting the buzzer 162. And S sounds an alarm, and the processing unit adjusts the frequency of the output wave width modulation signal according to the level of the car value of the buffering unit 15 temporarily. Ming's automatic warning device for vehicle direction lights says: , Acceleration _ Unit 1 () can detect whether the vehicle is turning 'flash (four) test 兀 13 can test whether the vehicle is not directional light, in addition, the processing unit μ Γ Simultaneously making the vehicle speed signal from the buffer unit 15 to determine that the abnormal driving condition processing unit 14 will correct the sensitivity according to the vehicle speed and the sensitivity of the (four) unit debt 2 angle, in response to the vehicle (four) vehicle speed and the direction of the steering direction from the (four) start direction 31, 32 Furthermore, the self-contained directional light of the vehicle of the present invention can not be cut and cut, and the frequency of the alarm sound can be adjusted with the speed of the vehicle to prompt the driver to pay attention. The risk of inadvertent driving may be reduced.
