Mobile WebSiteHonda, Toyota's fierce competition has been going on for many years, although the Honda car is only one-third of the volume of Toyota, the product coverage level is still unable to real confrontation with Toyota, but in the mainstream vehicle level, "Can be described as opponents every day.
Toyota relies on sophisticated and complex THS-II systems to dominate the field of hybrid for many years, "Prius" is a synonym for hybrids. In the face of many opponents, why not one can really challenge Toyota's hybrid technology? Cost, efficiency, ride comfort, only three, it is difficult to do the right of Toyota. After all, advanced and complex technology, and ultimately have to be used in commercial vehicles, and high-cost hybrid system is difficult to popularize.
It is so many years down, it is difficult to have other manufacturers can really challenge the reasons for Toyota hybrid technology. Until the old enemy (in fact, hot pursuit of Toyota) Honda launched a new generation of i-MMD hybrid system. Accord and Camry two hybrid mid-size car, for example, Accord equipped with i-MMD not only beyond the driving force of the Camry Swiss THS-II, fuel economy is also better. Experienced a few years ago in the doldrums, accepted numerous media criticism of the Honda, and finally recovered Mr. Zong Yilang left the soul and spirit, with innovative and continuous study of the spirit, with technology to create a truly high-quality products.
Our today's content will not be designed with obscure technical terms and structural descriptions, focusing on making it easier for you to understand the differences in the work of the two systems, as well as the differences in the real car level different.
Enough to challenge or even surpass THS-II's i-MMD
日本版丰田凯美瑞混动JC08燃效23.4km/L
日本版本田雅阁混动版JC08燃效30km/L
从日本本土JC08的测试结果来看（仅供国内参考），搭载了i-MMD的本田雅阁比搭载了THS-II的丰田凯美瑞的燃效要高出不少。而从我们之前试驾体验过的结果来看，混合动力版的雅阁在加速平顺性和动力性的表现上，也确实更加出色。换言之，本田通过了更简单的结构，不仅绕开了丰田一向以引为傲的混合动力专利技术，还实现了对“垄断”混合动力技术的丰田提出了最具威胁的挑战。
From the two hybrid systems, we have summarized the advantages of the i-MMD system for the THS-II system. Although the THS-II is still a true leader in "mixing" the power output from the two power sources. And in the ECVT technical level, still has a very high attainments. THS-II is still extremely advanced in terms of the technical level and the complexity of computing the power distribution ratio of the computer system, but for consumers, no matter what method, the results of direct goals are actually more important.
So, why i-MMD can go beyond the THS-II to the next level of better power and energy balance, we must understand the structure and work from the beginning, we will analyze the following two for your hybrid system Work, with you to understand the difference between the two systems.
First of all, we look at the famous Toyota THS-II hybrid system. It can be said, THS-II is the real "hybrid". why? Because it relies on extremely sophisticated structures and super-complex calculations that allow the engine and motor to drive the vehicle at the same time most of the time, in the enjoyment of conventional power models on the basis of direct sense and ride comfort, bring conventional power models can not match Fuel economy.
Toyota's THS-II pursues a complementary, low-speed and acceleration process between the motor and the engine, providing the main power source by a more direct and larger motor, while the engine plays a leading role in cruising and high speed Of the power output platform, when the motor is mostly auxiliary output.
And pure electric state, only in the low speed and smooth small throttle opening time, does not pursue the motor in the whole process of driving the maximum output. The entire system is optimized for the best output of the motor and the engine, and always keeps the two in the best possible condition. Of course, maintaining this situation requires a very complex algorithm, and by the Toyota THS-II core components ECVT mechanical level coordination. THS-II system will continue to adjust the different stages of the output of the two power source output ratio or switch, to ensure that ride comfort depends on ECVT.
The ECVT of the THS-II is not a conventional CVT gearbox, which is a combination of a planetary gear set and an auxiliary motor to provide an adjustable gear ratio. In addition to the above, in addition to the complex and accurate calculation of the computer, THS-II in the most important, the core component is this ECVT. It is really near the perfect engine and motor power mix together, but also the whole set of THS-II system in the core of the core, Toyota hybrid system, the main patented technology, it is also many manufacturers want to get rid of Toyota's dominance, Must go beyond the gap.
