Toyota's TNGA architecture has been known by the Chinese car market since 2016. As a new architecture for Toyota's globalization, people seem to understand the seemingly metaphysical concept, and in fact, TNGA translates from Toyota's new global Architecture, it is not only the product platform, but also the entire production system, manufacturing system, research and development system changes.
On October 19, Dong Changzheng, executive vice president of Toyota Motor China Investment Co., Ltd., made a very deep analysis of TNGA on the reorganization of the TNGA 'Feng Neng concept, which was organized by Huanqiu Automobile Group. The meaning is that Toyota recognizes that the change must be changed, can not hold old things in the past, these things are still inherited, but when the change must come up with a new thing.
Toyota has been to the 10 million, the future for the new energy vehicles, automatic driving cars, ICV smart cars, etc., the next step should be how to seek countermeasures, it has become the background of the TNGA architecture.Today Toyota standing on a 10 million on the steps, how will the TNGA architecture to break the two rebellious, re-manufacture of cars?
Improve the basic performance to improve product strength
TNGA is actually difficult to use a word summary, because it involves all aspects, all-encompassing, but in general can be divided into two aspects, one Toyota as a car manufacturer can not leave the fundamental is to create better products, the product strength, Basic performance to build up, we must first achieve the basis of the vehicle, vehicle quality or vehicle performance improvement, and want to achieve this goal, you need the company's internal system, research and development system has a supporting upgrade.
Vehicle performance to enhance the most basic first step is the vehicle driving, with the driving performance of the two parts, part of the power upgrade, and then one is the whole body structure, handling performance up, and these two parts are closely related.
Powertrain refers to the engine, gearbox plus HEV power system. Before the TNGA, the gearbox and the engine are developed in two departments, and then to the CE to match, which means that the efficiency is relatively low, the time of development Longer than the TNGA architecture, Toyota will also develop the development of the engine and transmission in the past, and strive to maximize the efficiency of the powertrain system, which in the engine, will further improve thermal efficiency, expand the low fuel consumption speed area, while improving Torque, to expand the gear ratio range of the transmission, and to the use of higher thermal efficiency field.In addition, Toyota also through high sensitivity control, the wide gear ratio of the loss caused by the minimum control.
In the TNGA architecture, Toyota will fully update the vehicle's powertrain, gearbox and HYBRID system, the future can improve the power performance of more than 15%. By improving the engine performance to improve vehicle fuel efficiency to make cars more fuel efficient, the traditional fuel tank can be increased by 25 % Of the fuel economy, hybrid models can also increase the fuel efficiency of 15% .2016 as released in 2016, the new 2.5L engine and 8-speed AT combination, as well as the new 2.5L engine and new hybrid system combination, while taking into account the power performance at the same time , To achieve excellent fuel economy.
While the other part of the performance related to the basic performance of the vehicle is the chassis, Toyota TNGA before the product in the low center of gravity on this one is the average level, TNGA can do the lowest center of gravity, the highest level of low center of gravity is not equal to low chassis, Toyota through TNGA to the engine and gearbox (if it is hybrid, its motor and battery), these can determine the location of the vehicle center of gravity, the impact of relatively large parts loaded into the vehicle at the bottom of the bottom position, rather than by reducing the chassis to achieve The
After the reduction of the center of gravity can bring a few benefits, the first is the vehicle in the high-speed cornering, including some stability, deflection angle will be greatly reduced.In addition, the machine cover can be reduced by 10 cm than the original, Play a larger space, the design of the product will become better to see. There are drivers position, look at the window outside the perspective will be more wide, the security has a greater improvement.
There is the stability of the vehicle is closely related to the body of the steel, the eighth generation of Camry and the future Toyota all the cars will take the vehicle side of the ring structure, it is a closed-loop structure, so that the whole body of the torsional rigidity, Thickness is a closed loop, not a single structure, and the body is connected together, torsional stiffness will be greatly improved.
Toyota through the TNGA reform, in the details of the vehicle and comfort also improved.Therefore, Toyota in all models of the seat installation basically have a connecting parts to connect parts, can be fixed to the vehicle above the rail, which means that The car body to open the distance in the high-speed extreme driving when the seat frame volume will increase, the stability of the driver in the seat will be worse.But after the TNGA reform, Toyota is now taking the seat and the bottom of the body directly Connected to the way, the entire vehicle occupants directly feel the stability will be greatly improved.
Toyota's TNGA upgrade, the new chassis and the new suspension system to improve, all of these large and small efforts to add together the body of the torsional rigidity, according to the different models can be increased by 30% to 65%. According to third- NCAP crash test, the Japanese car to get the highest five-star In fact, before the introduction of TNGA products, Toyota's car sales in China are 100% of the five-star level after TNGA, Toyota also carried out, for example, the first in the world into a small angle , 2 tons, 55 km per hour crash experiment, in terms of safety performance than ever done more stringent, higher requirements.
High-quality high-quality manufacturing of better cars
Another aspect of the TNGA is how to achieve high efficiency and quality to create a better car.Car development to the present, not the host factory to complete all the tasks, but also the need for strong cooperation with suppliers. In order to complete the manufacture of a better car such a goal.
TNGA is not to subvert the Toyota before all the repairer model, simply Toyota is continuing to continue the CE system, but also some parts of the general, but does not mean that all parts common. Toyota will be divided into two Part of the lower part of the car is closely related to the consumer but can not see the basic performance part, such as the engine part, power assembly part, chassis, suspension, these invisible, intangible, but precisely with the vehicle Basic performance has a direct relationship; consumers see, tangible appearance, interior, configuration, this part is defined as the upper part.
Specifically, the upper part or follow the original CE system, by each CE according to different models positioning, different regions of the preferences of consumers to more personalized, more customized R & D work. The second half of the consumer can not see , Intangible, performance by the TNGA parts of the basic performance of the upgrade up to spread to more models above, this is a difference.
TNGA concept, does not require all parts of Toyota to achieve a common, not to worry about Toyota will appear 'sets baby' phenomenon.From the figure can be seen, only the green part of the TNGA is the common parts. TNGA said Of the architecture and Volkswagen MQB platform common, TNGA in the A design ideas, design concept, is to create a better car, while the Volkswagen B is the meaning of building blocks. The so-called building blocks is to create a thing, get here Is this, and then moved there to ride in another car, but this building block will not change, while Toyota is relying on TNGA new architecture model to gradually improve vehicle performance quality, which is Toyota and the public in the car design The difference of thinking.
This is the core part of the Toyota TNGA - two sets of histograms, one is the time of work or R & D cost comparison, the blue part is the past, yellow and red is TNGA. Two tree comparison, one is the past, one is TNGA is the solution to this situation, TNGA rely on internal efficient structure changes, resources will be reduced by more than about 20% in the past. These savings Under the resources, not converted into profits, but re-used to further strengthen the product strength, the development of advanced technologies to help sustainable development, in order to face the future 'to create a better car' to form a virtuous circle, and ultimately achieve vehicle quality Do not increase the price, which is the meaning of TNGA.
TNGA is a philosophical philosophy, because it brings a new concept and methodology, redefine the 'car making' approach, and the traditional way of thinking is completely different, TNGA is the initiative to change, because it is Toyota's future strategic thinking, In the face of a rapidly changing environment, only the initiative to change, in order to achieve sustainable development. TNGA change the way, not a link, but the system, structural, chain of change and reconstruction.
