As shown in Fig. 2, illustrating the specific implementation process of said program with reference to detailed process：
Step 1, judge whether vehicle meets preset condition；If it is, entering step 2；If it has not, terminating flow；Wherein,The preset condition includes that gear is in neutral gear and vehicle without electric fault under high pressure.
Step 2, when vehicle meets preset condition, whether judge to connect with charge port is electric discharge rifle；If it is, intoStep 3；If it has not, terminating flow.
Step 3, after charge port is successfully connected with electric discharge rifle, discharge circuit is opened.
Step 4, according to the resistance value on the CC wake-up signals and electric discharge rifle cable in the discharge circuit, judge charge portWhether it is fully connected with electric discharge rifle；If it is, entering step 5；If it has not, terminating flow.
Step 5, when charge port is fully connected with electric discharge rifle, vehicle residual electric quantity is obtained.
Step 6, according to the resistance value in the residual electric quantity of vehicle and electric discharge rifle cable, the residue for calculating acquisition vehicle is continuousBoat value.
Step 7, it in the remaining continuation of the journey value for getting vehicle, and detects when forbidding motor-driven indication signal, obtainsThe first control signal that first control switch is pressed.
Step 8, it when getting the first control signal that the first control switch is pressed, obtains default remaining continuation of the journey and limitsValue.
Step 9, when getting the default remaining continuation of the journey limit value, it is default to judge whether the remaining continuation of the journey value of vehicle is more thanResidue continuation of the journey limit value；If it is, entering step 10；If it has not, terminating flow.
Step 10, it when the remaining continuation of the journey value of vehicle is more than default remaining continuation of the journey limit value, controls and guides vehicle progress highPressure powers on.
Step 11, after the completion of vehicle high pressure powers on, the signal that electric discharge rifle is locked is obtained.
Step 12, after electric discharge rifle is locked, control vehicle discharges.
Wherein, in control vehicle carries out discharge process, electric fault signal under high pressure is acquired, if collecting the high pressureAt least one in the preliminary filling relay short circuit of inside battery in lower electric fault or breaking, positive and negative anodes relay short circuit or open circuitKind, then it controls vehicle and stops electric discharge, terminate flow；In control vehicle carries out discharge process, do not exist collecting gear informationIt when neutral gear, prompts to hang to the information of neutral gear, such as " please hang to N and keep off ", and can also alarm, driver is prompted correctly to graspMake gear, prevents maloperation from leading to charge fault.
The embodiment of the present invention additionally provides a kind of vehicle-to-vehicle charging unit, as shown in figure 3, including：Two-way Vehicular charger24, for when vehicle meets preset condition, judge charge port whether with electric discharge rifle connect；Entire car controller 23, in instituteState two-way Vehicular charger 24 judge charge port with electric discharge rifle be fully connected when, control and vehicle guided to be powered on into horizontal high voltage；InstituteIt states two-way Vehicular charger 24 to be additionally operable to after the completion of the entire car controller 23 controls and vehicle high pressure is guided to power on, control is wholeVehicle discharges.
In the above embodiment of the present invention, by two-way Vehicular charger 24, for when vehicle meets preset condition, sentencingWhether disconnected charge port connect with electric discharge rifle；Entire car controller 23, for the two-way Vehicular charger 24 judge charge port andWhen electric discharge rifle is fully connected, controls and vehicle is guided to be powered on into horizontal high voltage；The two-way Vehicular charger 24 is additionally operable to describedAfter the completion of entire car controller 23 controls and vehicle high pressure is guided to power on, control vehicle discharges, and need not increase additional hardwareCan be completed it is vehicle-to-vehicle between charging, ensure the continual mileage of vehicle.
In the specific embodiment of the present invention, the two-way Vehicular charger 24 is specifically used for：Meet in vehicle and presets itemWhen part, whether what the two-way Vehicular charger 24 judged to connect with charge port is electric discharge rifle；In charge port and electric discharge rifle successAfter connection, the two-way Vehicular charger 24 opens discharge circuit；According in the discharge circuit CC wake-up signals and electric dischargeResistance value on rifle cable, the two-way Vehicular charger 24 judge whether charge port is fully connected with electric discharge rifle.Wherein, describedThe circuit diagram of two-way Vehicular charger 24 is as shown in figure 4, include：The battery of electric energy is provided；Pass through first switch with the batteryThe AC-DC control module of S1 connections, the AC-DC control module are connect by third switch S3 with charge port；WithThe DC-AC control module that the battery is connected by second switch S2, the DC-AC control module are opened by the 4thS4 is closed to connect with charge port；Wherein, the charger controller of the two-way Vehicular charger 24 by controller area network withCharge port connects, described two-way vehicle-mounted to fill if the two-way Vehicular charger 24 judges charge port and discharges after rifle is successfully connectedThe second switch S2 of motor 24 and the 4th switch S4 are closed, that is, open discharge circuit；If the two-way Vehicular charger 24 judgesAfter charge port is successfully connected with charging gun, the first switch S1 and third switch S3 of the two-way Vehicular charger 24 are closed, i.e.,Open charging circuit.
According to the resistance value on the CC wake-up signals and electric discharge rifle cable in the discharge circuit, the two-way vehicle-mounted chargeMachine 24 may determine that whether charge port is fully connected with electric discharge rifle, and can also get the capability value of discharge cable；Such as：When the resistance value in the connection of CC interfaces and electric discharge rifle cable in the discharge circuit is 2 kilo-ohms, charging interface is completeConnection, discharge capacity is 16A at this time；The resistance value in the connection of CC interfaces and electric discharge rifle cable in the discharge circuit is 1Kilo-ohm when, charging interface has been fully connected, at this time discharge capacity be 63A；In the discharge circuit CC interfaces connection andWhen the resistance value discharged on rifle cable is 220 Europe, charging interface has been fully connected, and discharge capacity is 32A at this time；It is put describedWhen CC interfaces in circuit are not connected with and the resistance value discharged on rifle cable is infinitely great, the interface of vehicle is in half-connection shapeState.
