(2) engine idle shutdown/quick start
In the car retardation process or meet red light or traffic congestion or other situation and when stopping; by making driving engine 1 oil-break, shutdown; avoided that existing internal-combustion engines vehicle slows down at this moment, idle oil consumption and exhaust emissions, be to improve the car load fuel economy and reduce one of Critical policies of tail gas noxious emission.According to integrated vehicle control tactics, when the need fire an engine, can be at any time by the double mode start-up function fire an engine of described driving engine, wherein, drag driving engine fast and generally adopt the pattern of motor 3 fire an engines, after a certain higher rotation speed, driving engine 1 is commencement of fuel injection, fuel oil consumption and the tail gas noxious emission of having avoided the available engine starting process to cause improve the car load fuel economy and reduce the tail gas noxious emission.
(3) pure electricity drives
When vehicle start stage or underload or low cruise, driving engine 1 is in running on the lower load, and its heat efficiency is low and exhaust emissions is not good.At this moment, can provide all torsion torque of car load driving by motor 3, realize zero-emission, first clutch 2 is in released state automatically under the control of first clutch electrical control actuator 14, avoided the expenditure of energy of towing astern driving engine 1.
(4) pure engine drive
When the driving torque of vehicle and the speed of a motor vehicle make driving engine 1 be operated in high efficient area, first clutch 2 is in bonding state automatically under the control of first clutch electrical control actuator 14, motor 3 idle running, second clutch 4 is in bonding state automatically under the control of second clutch electrical control actuator 15, realize pure engine drive, guarantee to optimize the efficient of driving engine 1 by feedback braking energy and driving generating, intelligent charge and the rechargeable electrical energy of closed-center system 11 is used in pure motorized motions fully efficiently, operating modes such as combination drive in parallel, improve car load efficient, and can avoid the electric weight of closed-center system 11 to lose fast, prolong its service life.When too low or power drive system can not be finished vehicular drive at described closed-center system 11 electric weight,, also fire an engine 1 is entered pure engine drive pattern according to the car load power demand.
(5) combination drive in parallel
When the big vehicle driving torque of needs such as vehicle brish acceleration or climbing or required vehicular drive moment of torsion increase fast, if the electric weight of closed-center system 11 is fit to provide required electricity to drive energy, after the speed of a motor vehicle is higher than setting value, then can be in driving engine 1 outputting power, motor 3 is moved by electric model, first clutch 2 is in bonding state automatically under the control of first clutch electrical control actuator 14, second clutch 4 is in bonding state automatically under the control of second clutch electrical control actuator 15, realize and the direct coupling of driving engine 1 outputting power combination drive pattern in parallel, can when obtaining good car load dynamic property, improve optimized for energy efficiency.
(6) generating combination drive
Dump energy at closed-center system 11 is less, driving engine 1 also has under the remaining situation after satisfying car load driving torque demand, can move by generator mode by making motor 3, replenish the closed-center system electric energy, the driving engine operating efficiency is improved, and be used to realize the electric quantity balancing of closed-center system 11 simultaneously and satisfy the requirement of car load dynamic property.In driving engine low efficiency district, the generating combination drive also can improve engine efficiency, expeditiously closed-center system 11 is charged simultaneously, and uses in follow-up pure electricity driving or power-assisted in parallel driving, can further improve system effectiveness.
(7) regenerative braking energy feedback
In car brakeing or moderating process, driving engine 1 stops oil and motor 3 by electrical generator work, enters the regenerative braking energy feedback pattern.Because first clutch 2 is switched to automatically under the control of second clutch electrical control actuator 15 or keeps released state, the energy feedback loss in efficiency that can avoid the towing astern to described driving engine 1 to cause, and can avoid automatically in the docking process engine stall, flame-out etc.Because second clutch 4 is switched to automatically under the control of second clutch electrical control actuator 15 or keeps bonding state.Since change speed gear box 5 increase the square effect, and remain mechanical connection with wheel 8, therefore can carry out regenerative brake and feedback energy at any time as required, feedback power is bigger.Therefore, can cancel the retarder that has now on the vehicle.
(8) intelligent charge
When driving, electric weight as closed-center system 11 is too low, and driving engine 1 also has under the remaining situation after satisfying car load driving torque demand, can move by generator mode by making motor 3, replenish the closed-center system electric energy, make the electric weight of closed-center system 11 surpass a setting value.
At dead ship condition, too low as the electric weight of closed-center system 11, can carry out the stopping for charging pattern.In the stopping for charging pattern, second clutch 4 is in released state automatically under the control of second clutch electrical control actuator 15, by pressing generation mode work with the motor 3 of driving engine 1 driving, gives closed-center system 11 chargings.After the electric weight of closed-center system 11 surpassed a setting value, the stopping for charging pattern finished.
In the intelligent charge pattern, charging current is according to dump energy, state of health and the environmental conditions of living in of closed-center system 11, and the operating point by control driving engine 1 and motor 3 provides rational charging current to closed-center system 11.
