Accompanying drawing explanation

Fig. 1 is the structured flowchart that present embodiment utilizes the automatic starting and stopping mechanism of electromotor of OBD technology.

Detailed description of the invention

Combine accompanying drawing below by detailed description of the invention this utility model is described in further detail.

Present embodiment utilizes the automatic starting and stopping mechanism of electromotor of OBD technology to include OBD data interface module (OBDM), central processing module (MCU), two radio fest and control relays and an automobile CAN-bus prison Survey module (namely for realizing the first radio fest and control relay J 1 of automatic starter function, for realizing certainly Move the second radio fest and control relay J 2 of extinction function and for realizing the automobile CAN of brake detecting function Bus monitoring module).OBD data interface module and automobile CAN-bus monitoring modular all process with central authorities Module connects, and processes delivering to central processing module after OBD real time data acquisition.Two wireless surveys Control relay replaces existing cranking-motor relay and the atomizer relay of automobile respectively, is installed to quilt accordingly Replace on original position of relay.

After automobile normal starting, central processing module starts OBD data-interface and automobile CAN-bus monitoring Module, and in real time monitoring OBD data in GES, engine rotational speed signal, throttle position signal, The signals such as the gear signal of automatic transmission, brake signal.When detecting that automobile is in braking state, and Automobile has stopped, and when not having the restriction of the first additional conditions, then mastery routine is wireless by second immediately Observing and controlling relay J 2 auto-action, controls engine misses immediately.When detecting that brake pedal is no longer stepped on It is issued to 2 seconds (or other duration preset), or when gas pedal is operated, attached without second The condition that adds limits, then mastery routine is immediately by the first radio fest and control relay J 1 auto-action, starts immediately Electromotor.

Mastery routine execution auto extinguishing condition:

1. vehicle immobilization, Vehicle speed=0 in data stream；

2. foot stepped on the brake pedal time more than 2 seconds, and Brake Sw=ON and time are more than 2s, and air throttle =CLOSE；

3. there is no the restriction of the first adnexa condition.

First additional conditions, close start-stop function, and the most in a case where, whether the most main condition meets, The electromotor started can not be automatically switched off:

1. driver actively closes, and APP has a switch or arranges a physical switch key；

2. the faulty existence of engine system, i.e. engine failure lamp is bright, MIL=ON；

3. electromotor and variator are not reaching to normal temperature, in data stream relevant parameter, and Engine coolant Temperature and Trans temperature temperature is less than 87 DEG C；Or OPEN/CLOSE LOOP= OPEN；Or Engine warm=NO；

4. variator is in P/N shelves；P/N switch=P-N；

5. variator is in motor pattern, Mode SW=SPORT；

6. outdoor temperature overheated (higher than design temperature) or supercool (less than design temperature), Outside temperature <-10 DEG C or>30 DEG C；

7. air-conditioning is not reaching to design temperature, Inside temperature < air-conditioning panel design temperature；

8. storage battery electricity is not enough, LOW BATTERY=YES；

9. turn to machine to work, Power steering=ON；

10. A/T gear position is in R shelves, PRNDL=R or REVERSE=YES；

11. vehicles are in the state of bringing to a halt, BRAKE SW=ON and Vehicle Speed ' and < arrange value.

12. were less than 1 minute from the time of start-stop last time function activation；

13. the most slowly move ahead if be again started up rear vehicle, as long as speed is not higher than 9 kilometers/hour, Vehicle Speed<9km/h。

Second additional conditions, i.e. situations below, the electromotor closed by start-stop function, it is impossible to automatically Start:

1. car door opening, Driver ' s door sw=on, or Passenger ' s door sw=on；

2. Seat belt sw=off do not fastened by seat belt；

3. hood opens Engine hood sw=on.

In present embodiment, each radio fest and control relay with radio function is set, it is possible to enter electromotor Row oil-break is flame-out to be controlled, it is possible to the electromotor stopped being restarted control such that it is able to do not breaking In the case of line is not relocated, self-defining logicality is joined in automobile.Can be wirelessly WIFI Or bluetooth, or other is capable of the wireless mode of data exchange.

In present embodiment, radio fest and control relay is with detecting function, it is possible to realize believing relay switch Number collection, the switch motion of relay can be detected, and switching signal can be passed to central processing module；Should Radio fest and control relay, for MCU, is equivalent to a sensor, can be in real time corresponding relay Actuating signal wirelessly feed back to MCU；Meanwhile, this detecting function can also be to MCU The current state of feddback relay device and the implementation status to MCU instruction.

For realizing utilizing the start-stop function of OBD data, need, on the basis of original starting and stopping working, to increase Add a new logic input.When attachment means lost efficacy, do not affect original any function.Meanwhile, again Can be according to the needs of new logic, real-time enters new logic superposition.And relay is exactly best node, By wireless connected mode, central processing module, needing the control instruction performed to be sent to relay, is held The corresponding function of row.

For start-up function, need the radio fest and control relay of a kind of logical "or", replace the starter of former car Relay.Driver's original starting vehicle functions does not affects, and what MCU controlled simultaneously restarts function, it is possible to To be completed by this radio fest and control relay, the input i.e. realizing two parallel relationship is defeated with one Go out, be independent of each other.In present embodiment, after only needing the startings signals of vehicles of former car and stopping working, restart letter Number one of input, this radio fest and control relay can close and start vehicle.

During it addition, be currently running for electromotor, need to interrupt its working condition, need a logical "and" Radio fest and control relay, replace atomizer relay (tentative by the way of oil-break, close and start Machine).This radio fest and control relay i.e. has two inputs, is series relationship.Only one of which disconnects, relay Device just disconnects, and atomizer just stops oil spout, reaches to control flame-out purpose.This series connection generally refers to relay Internal series-connection.Flame-out control in the case of normal working of engine and the flame-out control of automatic start-stop function, As long as wherein a road needs to allow engine misses, then the radio fest and control actuating of relay, engine misses.

It is above two kinds of relay, adds detecting function.Can be with Integrated design in a relay. The switching of "AND" "or" logic, may be changed by the way of wire jumper or switch.The most both decreased The kind of research and development of products, facilitates again installation, transports and debug.

Owing to relay is the big electric current of Small current control, this condition of live wire that wireless module needs has been provided with. But, ground wire differs to establish a capital and possesses.This just requires to need an external ground wire, the wireless mould in relay Block is powered.

Above content is to combine specific embodiment further detailed description of the utility model, no Can assert that of the present utility model being embodied as is confined to these explanations.Technology belonging to this utility model is led For the those of ordinary skill in territory, without departing from the concept of the premise utility, it is also possible to make some Simple deduction or replace.
