LS（Locking Switch）It is followed by magnetic induction loop SL（Solenoid）, magnetic induction loop SL control hydraulic control units and then to vehicle
Wheel is controlled, and magnetic induction loop SL two is terminated with LED light, can show that magnetic induction loop SL is worked by electricity, so as to know electronics
Differential lock working condition；And locking switch LS is controlled by artificial or electronic control unit.The locking of existing electronic differential lock is opened
It closes some to be controlled by external electronic control unit, cannot reflect in time for the operating status of electronic differential lock；Some electronics
The locking switch of differential lock uses foolproof control, and locking switch opens then differential lock and works, and locking switch closes then differential lock
Disconnection, electronic differential lock without disconnecting, braking the automatic control functions such as combination, the prompting of fault identification word automatically.
The content of the invention
The purpose of this utility model is to provide a kind of electronic differential lock with controller, the controls of the electronic differential lock
Device is associated through CAN network with entire car controller, can obtain the operation conditions of vehicle, is opened and closed so as to fulfill differential lock,
Achieve the purpose that vehicle is got rid of poverty.
In order to realize above-mentioned technical purpose, the utility model adopts the following technical solution：
A kind of electronic differential lock with controller, including controller ECU, magnetic induction loop SL, instant shut-in MS, indicator light
LED, controller ECU power inputs Battery are followed by automobile power source VB anodes, controller ECU ground terminals and vapour through fuse F
Vehicle power supply VB cathode are grounded, and controller ECU high drives die terminals HSD and low drive die terminals LSD and connects magnetic induction loop SL both ends, magnetic strength
Coil SL performs control element as electronic differential lock, and LED light one terminates the high drive die terminals HSD of controller, another termination of LED light
Ground, the CAN lines of the external vehicle CAN network in CAN Hi ends and CAN LO ends of controller ECU, connects with vehicle CAN network, control
DI termination instant shut-in MS one end of device ECU, instant shut-in MS other ends ground connection.
Electronic differential lock of the utility model with controller is used from tape controller, the controller through CAN network with it is whole
Vehicle controller is associated, and can obtain the operation conditions of vehicle, can open differential lock function in advance, while add safeguard protection work(
It can, it can be determined that open road conditions, can voluntarily disconnect, while may determine that fault state, differential can be realized by instant shut-in
Lock opens and closes, and achievees the purpose that vehicle is got rid of poverty.
Description of the drawings
Fig. 1 is existing electronic differential lock circuit theory schematic diagram；
Fig. 2 is the electronic differential lock circuit theory schematic diagram that the utility model carries controller.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Referring to Fig. 2, a kind of electronic differential lock with controller, including controller ECU, magnetic induction loop SL, instant shut-in
MS, indicator light LED, controller ECU power inputs Battery are followed by automobile power source VB anodes, controller ECU through fuse F
Ground terminal and automobile power source VB cathode ground connection, controller ECU high drive die terminals HSD and low drive die terminals LSD and connect magnetic induction loop
SL both ends, magnetic induction loop SL perform control element as electronic differential lock, and LED light one terminates the high drive die terminals HSD of controller,
The LED light other end is grounded, the CAN lines of the external vehicle CAN network in CAN Hi ends and CAN LO ends of controller ECU, with vehicle CAN
Network-in-dialing, DI termination instant shut-in MS one end of controller ECU, instant shut-in MS other ends ground connection.
The controller ECU can obtain the operating status of automobile by CAN network, such as pass through the gradient, steering angle, speed
Multiple signal crossbar logic is analyzed, and judges whether to need the opening and closing of differential lock.And controller ECU it is faulty identification with
Feedback function forms error code and is stored in controller ECU, read by outer computer, facilitate malfunction elimination and repair.Control
Device ECU also has operation prompting function, can prompt differential lock operation method, it is improper to eliminate by instrument face plate, indicator light LED
Operation.
The instant shut-in MS（Momentary Switch）Effect be a touch switch, can rule of thumb open
Open differential lock, prior involvement.User can be controlled by external instant shut-in MS, and differential lock open and close signal is input to
Controller ECU judges whether current vehicle working condition can open electronic differential lock by controller ECU, if can open, electricity
Sub- differential lock exports signal through magnetic induction loop SL, controls actuator（Hydraulic control unit）It opens, actuator is generated after being powered and pushed away
Power realizes differential lock function, achievees the purpose that vehicle is got rid of poverty；If it is determined that condition is unsatisfactory for, controller ECU exists feedback signal
Client is prompted in instrument, prompts the unlocking condition of electronic differential lock.
The magnetic induction loop SL（Solenoid）As electronic differential lock perform control element, control hydraulic control unit into
And wheel is controlled, it realizes differential lock function, achievees the purpose that vehicle is got rid of poverty.
The indicator light LED（Engagement Feedback and Warning LED）The effect of lamp can both do text
Word is reminded, and the state instruction that can work, so as to know electronic differential lock working condition.
The utility model is associated due to adding controller ECU, controller ECU through CAN network with entire car controller, from
