Embodiment Construction

[0020] see figure 1 , 2 3. The control principle diagram and partial schematic diagram of the automatic control system of automobile turn signal. It can be seen that the operating system only performs automatic control of the turn signal system through the wheel speed signal. It is set by the left and right wheel speed sensors 5, 6 Collect wheel speed signals. Of course, the wheel speed signals can also be shared through the automobile ABS system. The obtained wheel speed signals are transmitted to the ECU 8 through the electronic control unit 7. The electronic control unit 7 is a dual-channel signal processing circuit, which independently processes the left and right wheel. Speed ​​signal, electronic control unit 7 is equipped with amplifying, filtering, and shaping circuits, and the left and right wheel speed signals are respectively amplified, filtered, and shaped before being sent to ECU8. ECU8 is the core component of the system. Or a 16-bit single-chip microcomputer can...

Abstract

The invention reveals an automatic control system of an auto steering lamp, which is implemented through the steps that the control system acquires left and right wheel speed signals, the acquired left and right wheel speed signals are transmitted to an ECU by an electronic control unit, then the ECU drives left and right lamp relays to control a combination switch to realize the opening and closing of left and right steering lamp sets. The control system can accurately control the steering lamp, and the steering lamp can be opened accurately even by a slightest steering operation; meanwhile,the automatic control system and a manual operating lever can exist together to control the steering lamp, so that the drivers can operate the steering lamp more conveniently.

Description

technical field [0001] The invention relates to a control system and a control method for automatically turning on or off an automobile turn signal lamp. Background technique [0002] Car signal lights are a vital part of driving safety. Turning lights in the prior art are turned on mainly according to the steering intention of the driver, and the driver manually toggles the turning lights combination switch to light the turning lights for turning left or turning right. When the driver neglects to toggle the steering switch or is inconvenient to operate the steering switch, there may be traffic hazards, which can easily cause traffic accidents. For this reason, people have made turn signal automatic opening device. The utility model patent of CN2818229Y as Chinese Patent Publication No. discloses a kind of turn signal automatic opening device, and it comprises steering wheel, the angle sensor on the steering wheel shaft, speed sensor, control unit. In actual work, when th...
