Looking back on Toyota's 25-year history of hybrid development, it has experienced four generations of evolution. From the Prius equipped with the first-generation Toyota THS to the fourth-generation Highlander equipped with the fourth-generation THS2.0 dual-engine system and the E-FOUR electric four-wheel drive system, each generation of Toyota dual-engine hybrid system has improved its performance. In 2023, GAC Toyota will bring the latest intelligent electric hybrid dual-engine system. What changes have it made?
Intelligent electric hybrid dual engine closer to pure electric drive
Looking at the development of automobiles, it is not difficult to find that the final destination of automobiles in the future is to use clean energy as the driving source. At present, we are still in the era of energy transformation, and hybrid power is the best solution to overcome consumer anxiety. No matter what kind of hybrid system, in the iterative process, it gradually changes from fuel driving force to electric driving force, and the brand-new GAC Toyota intelligent electric hybrid dual-engine system is no exception.
GAC Toyota intelligent electric hybrid dual-engine system has comprehensively innovated the three-electric system, and comprehensively improved the performance of battery, motor and electronic control system.
The brand-new motor system uses a smaller and higher speed motor. By simplifying the coil structure, optimizing the magnet structure, increasing the strength of electromagnetic steel plate and upgrading the lubrication structure, the energy loss is reduced by 19% and the output power is increased by 32%. At the same time, with the efficient Atkinson engine, the comprehensive power of the hybrid system is increased by 6% (2.0L)/65,438+02%.
The new electronic control system PCU is further miniaturized, and the filter capacitor and miniaturized reactor are realized through the newly upgraded boost and high frequency. The weight is reduced by 17%, the energy loss is reduced by 10%, and the current output is increased by more than 8% (120A→ 130A).
In the past, all Toyota's hybrid cars used Ni-MH batteries, and the new fifth-generation THS2.0 dual-engine system replaced lithium batteries with smaller size, higher energy density and higher output power, achieving 8% power increase, 34% volume reduction and 44% weight reduction.
The comprehensive upgrade of the three power systems can improve the performance of Toyota's dual-engine system, which was originally based on fuel economy and long battery life. It has a battery and motor with higher output power, which allows the "electric drive" to cover more working conditions and bring a lighter sense of acceleration. Moreover, the shortcomings of Toyota dual-engine system, such as high engine speed and weak acceleration, have also been improved. It can be said that the new intelligent electric hybrid dual-engine system can bring more quality driving experience.
At present, the well-known hybrid systems on the market are Toyota THS and Honda imm-d. In contrast, Toyota's THS technologies in previous generations are mainly based on engine output, supplemented by motors, while Honda's IMM-D uses electricity as much as possible, so Honda will be stronger in performance, but in fact, their fuel consumption performance is almost the same.
However, this situation has changed now. In order to give consideration to thermal efficiency and performance, Toyota used a large displacement engine in the past, but now it has strengthened a brand-new intelligent electric hybrid dual-engine system in electric drive. With the original large displacement and high efficiency engine, the performance will achieve a qualitative leap. According to the news obtained so far, the vehicle equipped with the new intelligent electric hybrid dual-engine system will enter 7s with zero acceleration, which is outstanding in the current new energy vehicles.
Moreover, by increasing the bus current, the new intelligent electric hybrid dual-engine system can provide power for more intelligent devices and give vehicles more intelligent applications. The most prominent changes are the improvement of driver assistance system, intelligent cockpit and intelligent interconnection.
TSS2.0 is upgraded to T-PILOT intelligent driving with more comprehensive functions.
The performance of GAC Toyota TSS2.0 Zhixing safety system must be obvious to all. It is one of the few active safety systems with practical significance in the active safety collision test of easy car, but now it has been upgraded, with longer radar detection range, wider camera coverage, higher definition and more scenes to deal with road emergencies. The most important thing is that this new active security system supports OTA upgrade!
The brand-new T-PILOT intelligent driving system has been upgraded in all directions in terms of on-board sensors, and the detection distance of the front millimeter-wave radar has been increased to 340m, twice as much as before; The coverage angle of millimeter-wave radar and panorama camera is increased to 109.2 and 1 12, which is twice as much as before; The resolution of the forward-looking camera used to perceive the road information and lanes in front is also increased from 2.8 million pixels to 5.4 million pixels, which brings more accurate traffic sign recognition, lane recognition and more road information recognition capabilities.
Moreover, T-PILOT intelligent driving has 20 billion kilometers of driving data as a big data sample, which can basically cope with all the scenes encountered in daily driving.
The practicability of the pre-collision protection system is further enhanced. In addition to preventing head-on rear-end collision, it can also prevent head-on collision, steering collision, object collision and roadside collision, and increase the anti-collision ability of more road obstacles. Now it can cover pedestrians, bicycles, motorcycles, battery cars, large animals, telephone poles, houses, mountains, construction sites and so on. Of course, it also increases the driver's misjudgment. At a speed of 5 km/h,
The cruise function with higher daily driving frequency has also been strengthened, lane identification is more accurate, centering ability is stronger, lane keeping rate can reach 95%, the speed range of adaptive cruise is wider (0- 180km/h), the functions such as following the car are more natural, and the functions such as active avoidance, congestion reduction and ramp deceleration are upgraded, so that adaptive cruise covers more driving.
Judging from the performance of T-PILOT intelligent driving, it is already one of the most active safety protection systems on the market at present, which covers more application scenarios on the basis of strong practicability and can avoid traffic accidents to the greatest extent.
Among the existing products, GAC Toyota bZ4X is equipped with the latest TSS3.0 system, which already has the basic functions of T-PILOT intelligent driving. The TSS3.0 expansion package will be launched next year to realize the complete T-PILOT intelligent driving function, and T-PILOT intelligent driving will gradually cover more models.
Intelligent T-SMART and T-LINK
GAC Toyota will be equipped with a brand-new T-SMART intelligent cockpit system next year, supporting 2-3 ota upgrades every year, and will also be equipped with Qualcomm Snapdragon 8 155 high computing power chips in 2024.
The new T-SMART intelligent cockpit will be fully upgraded in terms of interactive hardware, voice control, application ecology and face ID.
The first is interactive hardware. The new T-SMART intelligent cockpit will be equipped with a new generation of 12.3-inch instrument panel and a new generation of intelligent in-vehicle system. It has four theme modes and supports customization to change the real content. It will launch a 10.25-inch central control screen that is more suitable for vehicle functions, providing touch control of vehicle functions and higher-definition panoramic images.
On the other hand, the voice becomes more localized and intelligent, which further improves the vehicle function control and recognizes the continuous voice control. In terms of application ecology, the car WeChat has been realized at present, and more localized entertainment applications will be gradually introduced in the future.
The mobile phone interconnection that everyone most wants to see is also realized on the brand-new T-SMART, which can adapt to the latest versions of Apple CarPlay, Huawei HICAR and Baidu CARLIFE.
T-Link intelligent interconnection enriches the functions on the basis of the original Fengyun Zhixing, and can realize remote control of vehicles, mobile phone intelligent key, intelligent parking and other functions.
The upgrade of T-SMART and T-LINK makes GAC Toyota products, which are already very practical, more competitive. Users can enjoy a more convenient and intelligent car experience in the car through the brand-new intelligent system, and the car you own will also become your travel partner who knows you best.
