the Pacific automotive network industry channel from the sixth generation Accord, Honda in left comfortable impression at the same time, on the athletic appearance and control settings for the people deep impression. When the popular global civic Type R, is more Honda movement gene into each fan head. With the global for fuel economy increasingly attention, the Japanese car overall in China product styles tend to energy saving, comfortable. With both energy and movement of German brand massive attack, orientation and brand force single slightly underdogs Japanese brand gradually defeated. The power assembly and product lines are not rich Honda, is stretched.

But a technology and sports known Honda is trying to change this situation. November 11, 2012 (due to sign a confidentiality agreement, news related only in Japan in November 13th 0 issue ), once a year "2012 Honda media conference " in Japan 's Honda Utsunomiya Institute of technology as held. On the meeting, Honda proud of " EARTH DREAMS TECHNOLOGY " powertrain plan, obtained a more widespread expansion. In addition to previously published i-VTEC direct injection engines and " G-Design Shift " CVT technology, three sets of hybrid powertrain and all wheel accurate steering technology ( PAWS ), Safety for Everyone technology was able to publish.

Earth Dreams powertrain technology

Three hybrid assembly also released

In the press conference, the new energy technology has become the leading role fully deserve. But Honda also broke the record industry, and released three application of different techniques for hybrid assembly. The three systems respectively by i-DCD, i-MMD, SH-AWD naming.

I-DCD

I-DCD assembly structure diagram

I-DCD is a 1.5L direct injection engine with dual clutch gearbox based on a hybrid device, motor mounted on the gearbox. Why choose DCT dual clutch transmission instead of the traditional power version of the CVT gearbox, Honda 's official explanation was the DCT shift time is shorter, can provide higher exercise.

I-DCD 1.5L engine and motor seven speed dual clutch.

The demonstration of this technique is based on a version of the old vehicle flying shell prototype vehicle, the front part can be obviously observed engine cover. According to speculation, the total will be applied in future Honda A0 as well as A-class products online, to replace the current IMA hybrid system.

I-MMD

I-MMD hybrid system called: Intelligent Multi Mode Drive. One set of medium-sized cars using dual motor structure of plug-in or a plug-in type intelligent multi-mode driving system. The system through a gearbox motor drive, in the torque phase of ascension in lieu of engine, drive a vehicle, and enters the high speed low torque phase, the combustion efficiency of the engine through the engine to provide power to reach the highest, is located on the front axle, using motor to drive a vehicle, so as to achieve the highest utilization efficiency of engine.

I-MMD plug-in hybrid diagram

In this Congress, we see the technology demonstration model based on the American version of the accord, a total of a plug-in hybrid and plug-in hybrid two. From the vehicle structure design, is not Prototype, is close to the production version of the basic. Two models are only slightly different aspects in the battery pack, a plug-in hybrid version of the battery more giant, and the steering wheel on the right has a plug-in interface switch.

Equipped with a i-MMD Plug-in system beauty version of the accord

Look from exterior and interior, two cars with the ordinary version of the Camry did not differ much, just in the instrument with the charging indicator and a power indicator to replace the engine tachometer. While the two models support the Honda Econ latest fuel-saving mode, but a little regret is the two vehicles can not provide the movement pattern, replace sb. 's brake charging to greater levels of B mode and HV pure electric mode.

Increased braking force stronger B file and pure electric mode, no motion mode

According to forecasting the 2.0L with CVT and double motor i-MMD system will be widely applied to the accord, the Odyssey, Aili gentry and other large products, become a Honda future main hybrid system.

SH-AWD

SH-AWD is the Honda published in hybrid systems, the most high-end version. The system will be equipped with the 3.5 liter V6 engine, in order to emphasize the assembly performance, with matching is one can carry bigger torque motor 7 speed dual clutch gearbox, in addition to gearbox motor, the system on the rear axle is equipped with double motors, in order to achieve the goal of four wheel drive. But this system is the biggest bright spot not only hereat, set through the rear wheels when in steering the wheel speed difference for battery charging, and through the motor to the rear wheel speed adjustment, realize vehicle stability enhancement.

Experience in the process, the front windshield with a wheel speed indication screen, a vehicle four wheel output can be clear in this screen was completely realistic. According to the introduction, this technology will be on the market next year Acura flagship model RLX pioneered the use of this system, the future will also be carried on a new generation of HRA super sports car based on NSX.

Fit EV

In addition, has been mass production, and by the end of this year or early next year at the Guangzhou Honda domestic electric fit also appeared together. The vehicle uses the integrated motor has three modes of operation. Sport mode, the car can be 92kw power, under normal mode power decreases to 75kW, in eco mode, the motor is maintained at about 45kw.

Fit EV used by small integrated motor

The car battery and the chassis are highly integrated, this body height decreased slightly, in order to adapt to the battery size, electric version of the fit of the H type torsion beam rear axle specialized into a multi-link independent suspension. In order to adapt to the fast charging, the cars respectively on both sides of the vehicle for the two charging interfaces. Fast charging time in about half an hour, and the slow filling time in about 6 hours. The actual form of a single mileage in between 135-140km, maximum speed of 140 km / h, but if normol or sport mode, the actual mileage may respond to lower.

Because of the battery occupied most of the space Fit EV chassis, rear suspension into independent multi-link suspension

PAWS ( all wheel steering technology. )

Of course, in addition to powertrain, Honda this also released in ascension and operation performance and improve vehicle safety performance technology, PAWS is one of them. Through the adjustment of the rear wheels of the vehicle tilt angle, so that the rear wheel to follow the steering.

The working principle of PAWS graph

When the steering angle is small ( such as high speed lane change ), the left and right rear wheel occurs simultaneously with the same angle of front wheel steering, achieve stable steering. When the steering angle is larger ( for example U turn ), increase the rear wheel toe angle of front (rear left and right wheels introverted), auxiliary vehicles to achieve stable speed brake, Ruwan, the left and right rear wheel occurs simultaneously with the front wheel opposite angle steering, improve the vehicle stability curve. It is reported, this technology will be on the market next year RLX two drive version with.

AEB

AEB system is a set of electronic brake system judgment. Through the front windshield glass with radar and camera, the vehicle will pre judgment ahead whether the vehicles and pedestrians, when determining the obstacles ahead, if the vehicle speed in 50km or less than 50km, the vehicle will automatically braked, if more than this interval, the vehicle will be the maximum braking to realize deceleration, to protect the pedestrians on the road.
