Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle headlight control, and in particular relates to a button headlight control device for a passenger car. Background Art

[0002] The automatic headlight control system for buses is an intelligent lighting control device designed to improve the safety and convenience of bus driving. Currently, the automatic headlight control systems used in European light buses mostly adopt a push-button switch control method, in which the button directly controls the power supply of the light sensor to control the light sensor signal output and realize the switching of the automatic headlight function.

[0003] However, the push-button automatic headlight switch currently used in European light commercial vehicles has a hold function. The push-button switch and light sensor are connected in series to the vehicle body controller. As a result, when the vehicle is restarted, the button remains in its previous state. This can easily prevent the driver from turning the automatic headlights back on automatically after turning them off and then restarting the vehicle, compromising driving safety.

[0029] like Figure 1As shown, the utility model provides a bus button headlight control device, which includes: a lighting module, a body control module, a switch button module and a light sensor.

[0030] The lighting module includes multiple lighting modules such as low beam, low beam and high beam. The lighting module is connected to the body control module and is controlled on and off by the body control module.

[0031] The body control module includes a control module and a lighting power module. The control module can be used to control the channel of the lighting power module. The lighting power module is connected to the lighting module, and the control module controls the on and off of the lighting module through the lighting power module.

[0032] The switch button module is connected to the control module for sending a switch signal to the control module; the light sensor is connected to the control module for sending a light signal to the control module; the control module controls the lighting module according to the signals of the light sensor and the switch button module.

[0033] To avoid the influence of the switch button module on the light sensor, the light sensor and the switch button module are respectively connected to the control module of the vehicle body control. Specifically, the power interface of the control module is connected to the light sensor and the switch button module, and is used to supply power to the light sensor and the switch button module when power is turned on, so that the light sensor is immediately turned on for lighting control when power is turned on.

[0034] By connecting the light sensor and the switch button module to the control module in the body control module respectively, when the vehicle is powered on for the first time, the power interface of the control module powers on the switch button module and the light sensor at the same time. At this time, the light sensor can directly feedback the signal to the body control module based on the detected light source, thereby realizing the control of the vehicle lights, realizing power-on and detection, and detection and control, and realizing the turning on of the headlights without being restricted by the switch button module and no longer having to adjust the on and off through the switch button module.

[0035] In this embodiment, the lighting power supply module includes multiple lighting power supply control circuits, and the lighting power supply control circuits include fuses and relays connected in series. The relays are also connected to the control module, and the control module controls the on and off of the relays, thereby controlling the on and off of the low beam, low beam or high beam of each branch in the lighting module.

[0036] Specifically, the light sensor includes a power conversion module, a single-chip microcomputer and a photosensor chip connected in sequence. The power conversion module is connected to the power interface of the control module, and power is provided to the power conversion module of the light sensor through the control module. The single-chip microcomputer is connected to the control module through an electronic switch, and is used to output a light signal to the control module. The electronic switch can realize high and low level switching, and the photosensor chip senses light and emits an electrical signal.

[0037] Specifically, the base of the electronic switch is connected to the output end of the single-chip microcomputer, the emitter of the electronic switch is connected to the output end of the power conversion module, and the collector of the electronic switch is connected to the control module. At the same time, the emitter of the electronic switch and the output end of the power module are grounded at the same time.

[0038] In this embodiment, the switch button module includes: a switch and an indicator light.

[0039] The switch S1 is connected between the vehicle power on gear and the control module, and is used to send a switch signal to the control module when the switch switches state. That is, when the switch state changes from a high-level signal to a floating signal, or from a floating signal to a high-level signal, it is considered a switch state change. In the figure, T15 is the vehicle power on gear;

[0040] The indicator light is connected to the power interface of the control module. One end of the indicator light is connected to the power interface of the control module through a resistor R34 and a diode D9, and the other end is grounded.

[0041] Diodes are connected between the control module and the light sensor, and between the control module and the switch button module. Specifically, the diodes are used to prevent cross-current between branches when there are multiple branches and different functional modules, and to avoid current flowing from one branch to another.

[0042] In this embodiment, when the vehicle is powered on, the body controller outputs a high level to the light sensor power supply and the indicator light on the switch button module, which controls the input of the LED light. At this point, the LED light on the push button switch illuminates. If the light sensor detects low ambient light outside, it outputs a low level to the body controller (BCM). The BCM, based on the low-level input signal from the light sensor, activates the relay in the internal light power module, illuminating the vehicle's low-beam and low-beam headlights.

[0043] Among them, the high-level signal output by BCM to the light sensor and switch must be automatically output each time the vehicle is started.

[0044] At the same time, during vehicle startup, the BCM monitors the input signal from the switch button module. If the switch input signal changes (from a high-level signal to a floating signal, or vice versa), the BCM stops outputting high-level signals to the light sensor and switch, turning off the LED on the switch button module. Regardless of ambient light levels, the light sensor will not output a low-level signal, and the BCM will not energize the internal light power relay, effectively turning off the headlights and automatically turning them on.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
