Description
Technical field
The utility model relates to the control field of motor, particularly a kind of engine intelligent start stop system.
Background technique
Energy crisis is increasingly serious, and the Abgasgesetz of country is increasingly strict, numerous automobile and manufacturers of engines using energy-conservation, reduce discharging an important directions as product R & D.Statistics is had to show, under city operations operating mode, dead time accounts for 1/3rd of total run time, engine long is caused to be in idle state temporally, cause the problems such as rotating speed is low, oil consumption is high, seriously polluted, and have relevant laws and regulations to have strict restriction to the engine idle time abroad, therefore engine idle on off control Shi Ge great automobile vendor strengthens one after another to motor start stop system exploitation dynamics.Many Foreign Automobile manufacturers develop a kind of idling start stop system, but this system needs to mate independently power supply unit, starting motor and control system, but due to motor start and stop frequently, very high request is proposed to the reliability of start stop system, traditional starting motor be difficult to solve long term frequent use bring life-span, integrity problem.
At present, what market realizes motor on off control mainly contains two kinds, the first is realized by reinforced starting motor, in structure and intensity, strengthening design is done to starting motor, from structural representation, engine starting system and common start up system structurally indifference can be found out, see Fig. 1, the start and stop of motor 1 are main or to be engaged with flywheel gear by starting motor 3 and realize, and starting motor 3 is controlled by duplex control switch 2.The second adds bel-drivenn mode to realize by ISG (IntegratedStarterandGenerator) motor, see Fig. 2, the start and stop of motor 1 drive belt 5 by ISG motor 4 thus drive motor 1 to start, and ISG motor 4 is controlled by duplex control switch 2.In addition, in the ordinary course of things, motor 1 is also equipped with cold-starting motor 6, the start and stop of motor 1 are engaged with flywheel gear by cold-starting motor 6 and are realized.
But in strengthening property starting motor system, this system architecture has following shortcoming: 1. this system adopts common mechanical structure to connect, and remain and carry out ato unit by the engagement of gear, starting torque is little, and when starting, noise is large.2. starting motor system adopts brush motor, and the life-span of brush motor is short, poor reliability.Owing to using after start stop system, the start and stop quantity of motor can far away higher than common vehicle start-stop time, strengthening property start stop system only can extend certain working life, is difficult to solve the problem that Long-Time Service causes the life-span low.3. the frequent use of start stop system, must cause the increase of car load power consumption, therefore must mate powerful generator and jumbo storage battery.In the second start stop system, major defect has: 1. by belt transmission, efficiency is lower.2., because ISG motor arranged separately by needs, bring certain difficulty therefore to the layout of car load.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
