Problems solved by technology

The logical confusion of this hardware leads to complaints and complaints from customers of MQB platform models
Volkswagen's engineers proposed to solve the defects of this design and quickly bring the models of the MQB platform to the market. However, most of the solutions are processor solutions. The dome light mold of the company needs to be completely redeveloped, and the engineers of Volkswagen are not satisfied with this solution

Embodiment Construction

[0026] like figure 1 As shown, a vehicle rear interior light control module based on the Volkswagen MQB platform of the present invention includes a power supply voltage stabilization filter module, a rear dome light left and right switch debounce circuit, a switch level signal conversion into a trigger signal module, and a two-way trigger MC14013 , A dual-channel drive bulb chip for dome light drive and a rear dome light status indicator.

[0027] The PWM (Pulse Width Modulation) input signal is a 200Hz square wave with a duty cycle of 0-100% output by the body controller when the door switch is opened. Since no processor solution is used, there are two solutions. One drives the load directly, and the other uses the set and reset states of a flip-flop to fade in and out. Due to the logic state switching, there will be a common problem of the MQB platform when directly driving the load. The dome light control module of the present invention adopts a trigger to realize the PW...

Abstract

The invention discloses an automotive rear indoor lamp control module. The rear indoor lamp control module comprises a power supply voltage stabilizing filtration module, a left-right switch de-twitter circuit for rear ceiling lamps, a module for converting a switch level signal to a trigger signal, a two-way trigger, a dual-channel driving bulb chip for driving the ceiling lamps, and status indicator lamps for the rear ceiling lamps, wherein the output of the left-right switch de-twitter circuit for the rear ceiling lamps is connected to the two-way trigger; the output end of the module for converting the switch level signal to the trigger signal is connected to the two-way trigger; the output of the two-way trigger is connected to the dual-channel driving bulb chip; the output of the dual-channel driving bulb chip is connected with the left and right rear ceiling lamps; and meanwhile, the output of the dual-channel driving bulb chip is also connected with the status indicator lamps for the rear ceiling lamps.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to a control module and a control method for a rear interior light of a vehicle. Background technique [0002] Models on the German Volkswagen MQB platform are global models, with an estimated annual output of about 3.5 million vehicles. The dome light control logic of this platform is chaotic. When the rear operator uses the rear dome light switch to light up the rear dome light, the front row operator has no way to turn off the rear dome light; the same situation is that the front operator turns on the rear dome light. Under certain circumstances, the rear operator has no way to turn it off. The logical confusion of this hardware has led to complaints and complaints from customers of MQB platform models. Volkswagen's engineers proposed to solve the defects of this design and quickly bring the models of the MQB platform to the market. However, most of the s...
