Description

A kind of limping function module

Technical field

The utility model belongs to vehicle electronic circuit technical field, and in particular to a kind of limping function module.

Background technology

With the development of automotive electronic technology, the requirement of safety, comfort etc. is continuously improved, body electric system is in vehicle On application it is more and more, while also bringing the problems such as cost increases, failure rate rises, wiring is complicated.Then it needs to design Powerful control module is realized these discrete control functions, is controlled numerous electrical appliances, here it is Body Controls Module, referred to as BCM.

Car body control module function includes mainly：Signal light control scrapes water washing control, centrally controrlled locking system control, remote-control anti-theft Control, power distribution etc..BCM integration degrees are high, once breaking down, the function of being partly related to traffic safety will be by shadow It rings.

Utility model content

The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art provides a kind of limping function mould Block can individually carry out the hardware controls of car body controller, increase vehicle security, reliability.

In order to solve the above technical problems, the utility model provides a kind of limping function mould suitable for car body controller Block, including car body controller and be connected with car body controller braking lamp module, wiper module, external lights module, it is special Sign is that car body controller connects limping function module, and the braking lamp module control terminal of car body controller connects Brake lamp all the way Module, another way are connected with the braking lamp module control terminal of limping function module；The wiper module control terminal of car body controller Wiper module is connected all the way, and another way is connected with the wiper module control terminal of limping function module, outside car body controller Portion's light modules control terminal connects external lights module, the external lights module control terminal of another way and limping function module all the way It is connected.

The technical solution that the utility model further limits is：The braking lamp module control terminal of limping function module passes through system Dynamic lamp switch and mos pipes are connected with Brake lamp.

Further, the wiper control terminal of limping function module uses comparator circuit, passes through triode and wiper Slowspeed machine is connected, and when comparator exports high level, driving triode ON, windscreen wiper slow-speed relay is attracted driving windscreen wiper low speed Motor low-speed running.

Further, the external lights module control terminal of limping function module uses comparator circuit, works as External lighting switch Input exports high level in state other than OFF grades, comparator circuit, drives triode ON, dipped headlight relay coil logical Electricity, tip side are attracted, and light dipped headlight；Activation point lamp mos pipes conducting simultaneously, turned-on position lamp.

The utility model has the beneficial effects that：In car body controller, individually increases limping function module, work as Body Control When device fails, limping function module individually carries out hardware controls, to increase vehicle safety to being related to the function of traffic safety Property, reliability.

Specific implementation mode

Embodiment 1

A kind of limping function module suitable for car body controller provided in this embodiment, as shown in Figure 1, including vehicle body control Device processed and the braking lamp module being connected with car body controller, wiper module, external lights module, which is characterized in that vehicle body control Device processed connects limping function module, and the braking lamp module control terminal of car body controller connect braking lamp module all the way, another way and The braking lamp module control terminal of limping function module is connected；The wiper module control terminal of car body controller connects wiper all the way Module, another way are connected with the wiper module control terminal of limping function module, the external lights module control of car body controller End connects external lights module all the way, and another way is connected with the external lights module control terminal of limping function module.

As shown in Fig. 2, the braking lamp module control terminal of limping function module passes through braking light switch and mos pipes and Brake lamp It is connected, ignition switch ON, braking light switch is effective, BCM master chips, crystal oscillator or power module failure, the braking of limping module drive Lamp is lighted.

As shown in figure 3, the wiper control terminal of limping function module uses comparator circuit, pass through triode and wiper Slowspeed machine is connected, and when wiper switch is in non-OFF and interval shelves, comparator exports high level, drives triode ON, windscreen wiper Slow-speed relay is attracted driving windscreen wiper slowspeed machine low-speed running.

As shown in figure 4, the external lights module control terminal of limping function module uses comparator circuit, work as External lighting switch Input exports high level in state other than OFF grades, comparator circuit, drives triode ON, dipped headlight relay coil logical Electricity, tip side are attracted, and light dipped headlight；Activation point lamp mos pipes conducting simultaneously, turned-on position lamp.

Test result：

Ignition switch ON, compares common car body controller and the car body controller of the function module containing limping, and test result is shown in Following table：

Individually increase limping function module in car body controller, when car body controller fails, limping function module is to relating to And the function of traffic safety, hardware controls are individually carried out, to increase vehicle security, reliability

In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
