As shown in table 1 below, be oil-electric vehicle under each operating mode, the duty of each electromagnetic valve and two charcoal canisters in the present invention:
Table 1
Referring to table 1, automobile is in refueling process, and the first electromagnetic valve 45 is opened, and the second electromagnetic valve 35 cuts out, and the 3rd electromagnetic valve 46 cuts out, and the 4th electromagnetic valve 36 cuts out, and the first charcoal canister 4 is in adsorbed state, and the second charcoal canister 3 does not work.Automobile parking is the same with the state under electric-only mode when travelling, and the first electromagnetic valve 45 cuts out, and the second electromagnetic valve 35 is opened, and the 3rd electromagnetic valve 46 cuts out, and the 4th electromagnetic valve 36 cuts out, and the first charcoal canister 4 does not work, and the second charcoal canister 3 is in adsorbed state.During running car the same with state in composite mode under engine mode, first electromagnetic valve 45 and the second electromagnetic valve 35 are constantly in closed mode, 3rd electromagnetic valve 46 and the 4th electromagnetic valve 36 are in closedown or open mode, and the first charcoal canister 4 and the second charcoal canister 3 are in detachment status.
It is as follows that first charcoal canister 4 and the absorption of the second charcoal canister 3 and desorption control process:
The absorption and control flow process of the first charcoal canister 4 and the second charcoal canister 3 is as shown in Figure 2, first, under oil-electric vehicle is in fueling state, open filling pipe cap 15 when refueling a car, nozzle inserts oil filling pipe 12, add oil sensor 14 and detect that automobile is at fueling state, add oil sensor 14 and send signal to ECU5；When ECU5 receives fueling signal, signal is sent to first electromagnetic valve the 45, second electromagnetic valve 35, open the first electromagnetic valve 45, simultaneously close off the second electromagnetic valve 35, the oil gas produced in fuel tank 1 in automobile fuel filler process enters in the first charcoal canister 4 by after oil gas multiple-way valve the 11, first pipeline the 61, the 3rd pipeline 63, and clean air enters air from the first atmospheric air port 41.Secondly, when being at oil-electric vehicle under parking and electric-only mode, namely detect that automobile is not when fueling state, ECU5 sends signal to first electromagnetic valve the 45, second electromagnetic valve 35, closing the first electromagnetic valve 45, the first charcoal canister 4 stops absorption oiling oil gas, opens the second electromagnetic valve 35, second charcoal canister 3 starts to adsorb the oil gas produced under other states, and clean air enters air from second largest QI KOU 31.
nullThe desorption control flow of the first charcoal canister 4 and the second charcoal canister 3 is as shown in Figure 3，When being in when oil-electric vehicle under engine mode and mixed model，By vehicle speed sensor 59 and crankshaft position sensor 58, ECU5 judges whether automobile engine is in operating condition，When automobile starting，Vehicle speed sensor 59 and crankshaft position sensor 58 send signal to ECU5 simultaneously，If by vehicle speed sensor 59 detect speed more than 0 and by crankshaft position sensor 58 detect that crank position changes time，Namely automobile engine is in operating condition，ECU5 is successively to the 3rd electromagnetic valve 46、4th electromagnetic valve 36 sends signal，Open the 3rd electromagnetic valve 46，Close the 4th electromagnetic valve 36，Now，The vacuum at electromotor 2 inlet manifold place promotes the first charcoal canister 4 to proceed by desorption，Air enters the first charcoal canister 4 from the first atmospheric air port 41 and washes away activated carbon，After a period of time，When the first hydrocarbon concentration sensor 44 detects hydrocarbon concentration lower than the ECU5 hydrocarbon concentration limit preset，The signal closing the 3rd electromagnetic valve 46 and the signal opening the 4th electromagnetic valve 36 is sent to ECU5，First charcoal canister 4 desorption process terminates；Otherwise proceed desorption.If the first charcoal canister 4 desorption process terminates, in like manner, the second charcoal canister 3 desorption process starts, until the desorption process of whole second charcoal canister 3 terminates.
In the present invention, speed more than 0 and crank position change refer to that the oil mixed electrical automobile electrokinetic cell electricity of electricity is lower than minimum limit value, automobile enters mixed dynamic model formula, force start driven by engine automobile runs.The minimum limit value of battery electric quantity is different corresponding to the oil-electric vehicle of each model, and concrete numerical value is this oil-electric vehicle design value.If electrokinetic cell electricity is in running status higher than described minimum limit value and automobile, now automobile is electric-only mode, and the oil gas produced in fuel system enters the second charcoal canister 3.
In oil-electric vehicle driving process, only when Vehicular accumulator cell electricity is set by each automobile vendor more than the a%(a value setting electricity) time, automobile just can start electric-only mode.Under electric-only mode, in refueling process, the oil gas of the first charcoal canister 4 absorption cannot be carried out desorption and processes, but when electricity is lower than the a% of setting electricity, in order to meet automobile power sexual demand, engine start, electromotor is consuming while fuel tank 1 intermediate fuel oil the first charcoal canister 4 by carrying out desorption, and this process necessarily occurs upper once before refueling process starts, namely upper once before refueling process starts, in the first charcoal canister 4, the oil gas of absorption can by timely desorption.Therefore, the control strategy according to oil electric mixed dynamic electric automobile, during auto idle speed, motor operation and electromotor is inoperative, if now force start electromotor can increase the overall oil consumption of automobile, and the present invention can avoid the occurrence of the situation of force start electromotor.The present invention in the course of the work need not force start electromotor, be operated fully according to existing oil-electric vehicle control strategy, upper once before refueling process starts, in the first charcoal canister 4, the oil gas of absorption will necessarily complete desorption.
