Description
Technical field
The present invention relates to vehicle electric fields, more particularly to a kind of doorlock control unit of passenger car.
Background technique
Using the doorlock control unit of mainstream (referred to as gating) in control unlock, locking or super lock on existing passenger car
When generally use control mode as shown in Figure 1.That is, the control signal issued by doorlock control unit acquisition user, for example door
Switch is controlled in lock, wireless key signal, mechanical lock switch etc., the electronic control unit in doorlock control unit is (hereinafter referred to as
MCU) according to collected signal, after carrying out logical operation by software, driving signal is issued to relay module, by relay
Module output voltage/electric current, door-lock motor execute corresponding locking, unlock or super lock movement.
The defect of existing doorlock control unit control mode is primarily present following two defect:
One, all control functions all rely on its core devices MCU, if MCU break down or its in software
Program breaks down (MCU failure), and gate can lose the drive control to door-lock motor.Such situation is known as the failure mould of door lock
Formula, under failure mode, then there is security risk in the case where if it happens cannot unlocking, for example accident or vehicle will intake
When, it causes user that cannot unlock and leaves vehicle.
Two, if the motor drive module (relay) in gate is viscous if it is locking drive module occur mechanical viscous
Stagnant, then door-lock motor is locked always direction driving, can equally generate security risk, for example accident or vehicle will intake
In the case of, it causes user that cannot unlock and leaves vehicle.
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind to gate interior motor drive module (relay) hair in passenger car
The doorlock control unit that can be unlocked safely in the viscous situation of life tool.
Passenger car doorlock control unit provided by the invention, comprising: MCU, Acquisition Circuit and door lock relay；
Two output end of door lock relay connects Acquisition Circuit, and Acquisition Circuit can detect door lock relay output end level and will
The level is sent to MCU, and the relay output end level received is compared by MCU with MCU logic control instruction, MCU root
Whether unlock according to comparison result control door lock relay.
Be further improved, Acquisition Circuit when collecting high level and MCU logic control instruction does not export high level,
MCU forces two output ports of opening door lock relay simultaneously, makes two output port equipotentials.
It is further improved, after two output port equipotentials of door lock relay, closes the output of door lock relay, acquisition electricity
Road disconnects unlock relay output when detecting low level.
Due to the time (generally less than 100ms) of motor operating very little, so that it may actual mechanical structure locking is formed,
So being adjusted to extremely short (be less than preferably with interrupt input or sampling time for relay high level feedback port
100ms), then take immediate measure holding circuit both ends equipotential.After the equipotential of motor both ends, gate can also attempt to extensive
Multiple strategy.Be first shut off locking relay output, detect and be fed back to low level, indicate locking relay it is not viscous when
It waits, then disconnects unlock relay output, system restores normal later, and function can reuse.
It is further improved, the feedback collection at relay high level output end is inputted using interrupt.
It is further improved, the Acquisition Circuit sampling time interval is less than or equal to 10ms.
There are two collection terminal and two output ends for the Acquisition Circuit tool, comprising: first resistor one end is as acquisition electricity
The first collection terminal other end on road as the Acquisition Circuit the first output end and pass through 3rd resistor be grounded；Second resistance one end
As the Acquisition Circuit the second collection terminal other end as the Acquisition Circuit second output terminal and pass through the 4th resistance eutral grounding；
First collection terminal is grounded by first diode, and the second collection terminal is grounded by the second diode.
Passenger car doorlock control unit of the invention will be by the way that two output end level detection of door lock relay, MCU will be received
To relay output end level be compared with MCU logic control instruction that judge whether to occur relay viscous, MCU according to than
Whether relatively result control door lock relay unlocks.It is mechanical viscous interior motor drive module (relay) generation to be gated in passenger car
It is that compulsive unlocking is carried out to car door, guarantees unlocking function, prevents the case where user is locked in the car, avoid security risk, mention
High vehicle safety.

Specific embodiment
As shown in Fig. 2, motor drive module (relay) generation provided by the invention in passenger car gates is mechanical viscous
In the case of one embodiment of doorlock control unit that can unlock safely, comprising: MCU, Acquisition Circuit Monitor and door lock bridge-type relay
Device (the present embodiment is by taking bridge type relay as an example)；
Two output end of door lock relay connects Acquisition Circuit Monitor, and Acquisition Circuit Monitor can detect door lock bridge-type
The level is simultaneously sent to MCU by relay output end level (such as high level), and MCU is defeated by the door lock bridge type relay received
Outlet level is compared with MCU logic control instruction (whether requiring output high level), and MCU controls door lock according to comparison result
Whether bridge type relay unlocks.
For Acquisition Circuit Monitor when collecting high level and MCU logic control instruction does not export high level, MCU is strong
System while opening door lock bridge type relay two output ports C, D, make two output port C, D equipotentials；
Due to the time (generally less than 100ms) of motor operating very little, so that it may actual mechanical structure locking is formed,
So for relay high level feedback port, be adjusted to preferably with interrupt input or sampling time it is extremely short, then at once
It takes measures to keep bridge circuit both ends equipotential.After the equipotential of motor both ends, gate can also attempt to recovery policy.First
The output for closing locking relay, detects and is fed back to low level, when indicating that locking relay is not viscous, then disconnects unlock
Relay output, system restores normal later, and unlocking function can reuse；
It is further improved, the door lock bridge type relay high level output end is inputted using interrupt or the Acquisition Circuit
Monitor can also be less than or equal to the form of 10ms using sampling time interval.
As shown in figure 3, Acquisition Circuit specific embodiment of the present invention, there are two collection terminal E, F and two are defeated for Acquisition Circuit tool
Outlet G, H, the one end first resistor R1 as the Acquisition Circuit the first collection terminal E other end as the first defeated of the Acquisition Circuit
Outlet G is simultaneously grounded by 3rd resistor R3；Second collection terminal F other end conduct of the one end second resistance R2 as the Acquisition Circuit
The second output terminal H of the Acquisition Circuit is simultaneously grounded by the 4th resistance R4；First collection terminal E is grounded by first diode D1,
Second collection terminal F is grounded by the second diode D2.
When the Acquisition Circuit works, first, second collection terminal E, F is separately connected door lock bridge type relay two outputs
End, first, second output end G, H output acquisition signal to MCU.
Above by specific embodiment and embodiment, invention is explained in detail, but these are not composition pair
Limitation of the invention.Without departing from the principles of the present invention, those skilled in the art can also make many deformations and change
Into these also should be regarded as protection scope of the present invention.
