How about Japanese Toyota hybrid technology? Toyota and Lexus show up: Black technology is durable and practical
The country's requirements for fuel consumption and emissions are becoming increasingly strict, and every car company is under tremendous pressure. How to achieve energy conservation and emission reduction is a problem that must be faced at present. Although electric vehicles and fuel cell vehicles have their own advantages, before the battery technology has a qualitative leap, hybrid power still has a broad market prospect and is the most realistic and effective energy-saving method.
The meaning of "mixed" can be understood as the "mixing" of internal combustion engine and electric motor, the "mixing" of fuel and electric energy, so when you see that there are two or more energy or energy converters to drive energy, you can conclude It is a hybrid.
Technical madman Honda has made three sets of hybrid systems, high, medium and low. Among them, the most famous is the i-MMD system used in the Accord, which is claimed to be the most efficient system in the world.
From the BBA to the public, to the domestic, this time finally finally turned to the Japanese manufacturers known as "black technology."
When it comes to Japanese manufacturers, the first thing that has to bear the brunt is Toyota, which has now developed into the world's number one automaker. Of course, it also includes Toyota's luxury brand Lexus. Regarding the attitude of automobile technology, Toyota seems to always have the feeling of taking consumers as "children". It is not absolutely sure, and it is easy to not shoot.
I believe that many people have seen various black technology configurations from Toyota in different media and channels, and these technologies are also full of the consistent style of Japanese companies, rigorous, practical and creative. So, Toyota and Lexus have some technical highlights worthy of attention, we can take a look together.
It is undoubtedly the Toyota's various "double-engine" models, which are currently the most popular hybrid models in China. The dual-engine is actually Toyota's hybrid system, and in terms of hybrid technology, Toyota now has a unique leading position in the world.
When it comes to mixing, the first thing that people think of is the term “plug-in hybridâ€. This hybrid method needs to charge the car battery through an external power source just like an electric car.
Toyota's hybrids are completely different and do not require charging. Simply put, you only need to refuel like a normal fuel car, and Toyota's hybrid system will rely on the excess power of the engine to charge the battery pack. And in the cycle of the entire hybrid system, Toyota relies on years of research and development to ensure stability and economy, so in the non-plug-in hybrid technology, Toyota can be said to be "out of the world."
Toyota's latest THS II hybrid system uses small, lightweight and low-loss technology. Among them, during high-speed driving, the system efficiency is improved, and the engine intermittent operation is realized, thereby further improving the fuel economy during high-speed driving.
In addition to mixing, Toyota is still in a leading position in another type of new energy source. That's right, it is a hydrogen fuel cell. At present, Toyota has launched Mirai, a hydrogen fuel cell vehicle. Not only is it a very sharp shape, but also a place worthy of attention, it is undoubtedly a special "hydrogen fuel" identity.
Mirai's driving method is to react hydrogen and oxygen in the fuel cell stack. Just like a small power station, the fuel is hydrogen. Hydrogen and oxygen synthesize water (not combustion) through the action of a catalyst, during which electrons are emitted and current is formed to power the motor or to charge the battery. Mirai's hydrogen fuel cells have achieved world-class power and can supply up to 60kWh of power with a maximum power supply of 9kW.
Toyota Mirai can fill 5 kilograms of hydrogen in just 3 minutes, and the cruising range can reach 650 kilometers, which can fully meet the needs of a halfway trip.
Compared with electric vehicles, hydrogen fuel cells have three advantages, including adding fuel faster than electric vehicles, and the battery life is significantly higher than mainstream electric vehicles. There is also the problem of emissions. Hydrogen fuel cells are truly pollution-free and environmentally friendly energy sources. The only products that emit water are water, which will not cause any pollution.
In terms of safety features, Toyota and Lexus are also unique in nature, and various safety functions and intelligent assisted driving characteristics are also quite rich. Including pre-crash safety system, lane keeping assist system, high beam automatic control system, parallel blind spot monitoring system, and reverse side blind spot warning system.
The pre-crash safety system connects the driving computer to the front sensor to alert the driver to avoid collisions and activate the damage mitigation device to help reduce the damage. When the collision detector ECU determines that the possibility of collision is large, the collision braking assist function PBA will be activated to help decelerate by increasing the brake hydraulic pressure; when it is judged that the collision is unavoidable, the collision detector ECU will send a signal to activate Braking before collision helps reduce the damage caused by a collision.
At the same time, the tail millimeter wave radar detects and analyzes the obstacle behind the vehicle, activates the tail danger warning light and the pre-crash cervical vertebra damage mitigation function before the collision to reduce the damage caused to the cervical vertebra. In addition, the upgraded system integrates the night vision system and the driver's closed-eye monitor function, greatly avoiding the potential risks caused by night driving and driver drowsiness, and comprehensively ensuring the safety of the occupants in the vehicle.
The lane keeping assist system allows us to identify and confirm the surrounding lane markings through the camera while driving, to ensure the position of the vehicle between the marking lines. When the vehicle deviates from the lane, the system alerts the driver to the lane by issuing a warning signal and applying a small amount of steering force.
It is also very dangerous and troublesome for the other party to drive the high beam or the rear vehicle to drive the high beam. The Toyota high beam automatic control system can detect the opposite vehicle light and automatically switch the high beam to low beam illumination. Avoid the brightness of the high beam to cause dazzling effect on the other's line of sight, and increase the driving safety of both sides.
When we are driving in the lane, if we want to change lanes or line, then the equipped blind spot monitoring system can detect the presence of vehicles entering the blinds of the exterior mirrors through the side-back radar before changing lanes. The indicator light on the rearview mirror will flash to alert the driver to the rear car, thus avoiding the occurrence of defects.
For novices, reversing is also a problem. The rear side blind area that cannot be observed through the rearview mirror when reversing is a hotbed of danger. The rear side blind spot warning system will use the radar to monitor the approaching vehicle appearing in the blind zone, and beep, and the flashing indicator light on the rearview mirror will remind the driver.
Toyota is also involved in car networking, cloud technology, big data and remote control of smartphones, and has begun testing ITS Connect coordinated security technology on some models.
This is a communication technology between vehicles based on V2V and V2I. The information exchange between the vehicle and the infrastructure can realize the traffic status reminder at the intersection, the vehicle formation cruise and other functions.
Initially, the ITS system was used in the aviation field, and the passenger airliners were equipped with a TCAS air collision avoidance system, which was able to detect whether other aircraft entered the collision danger range, thereby prompting the driver to make a pull-up or lowering action by voice. Avoid collision risks.
Toyota's ITS system can also have a similar effect, but it has changed from the air to the ground. The ITS system utilizes a dedicated frequency band of 760MHz to realize communication between roads and vehicles and between vehicles and vehicles. By acquiring information that cannot be fully captured by on-board sensors, the ITS system is matched with the autonomous safety driving assistance system to further reduce the risk of accidents. Generally speaking, it is a small crossroad with a bad view and no traffic lights. When other vehicles are found to move fast from the side roads, the ITS system will prompt the driver to pay attention to the road condition through the sound and LCD prompts, slow down and avoid collision. .
ITS not only enables safe-haven cues between cars and cars, but also receives a wider range of safety-environment reports through monitors set up at intersections. For example, when you want to turn left, there is a straight-going car in the opposite direction, and the system will prompt the driver to slow down. In addition, when a pedestrian crosses the road and the intersection is red, the system will also make an active reminder, becoming a sleepless electronic traffic police. Of course, to achieve these two functions, additional infrastructure needs to be built.
When it comes to semi-automatic driving, everyone must think of Tesla, Audi and other European and American manufacturers. In fact, Japanese manufacturers, led by Toyota, have made good progress.
Toyota's semi-automatic driving technology has been able to compete with humans on the highway. After entering the toll station, it will automatically accelerate, parallel line, lane keeping, encounter slow train overtaking, encounter slow deceleration, and then automatically connect to the line when exiting.
At the same time, Toyota's semi-automatic driving can travel quickly and smoothly in the lane in the corner. For different corner angles, its logic is also very accurate, and it feels like a real driver is driving. When the line is automatically connected, the system automatically selects the inner fast lane according to the GPS speed limit. Even before turning on the line, don't forget to turn on the turn signal, it is a qualified "driver".
At the same time, the system will also use the multiple radars and cameras of the body to determine whether it is safe to cross or directly overtake.
In fact, in many people's impressions, when it comes to Japanese cars, it is not bad and practical, but it is rarely tried on high technology. However, in fact, Japanese manufacturers, led by Toyota, have been working hard on technology exploration.
Regarding the attitude of automobile technology, Toyota seems to always have the feeling of taking consumers as "children". It is not absolutely sure, and it is easy to not shoot. But once it is shot, it is the most stable, best-used and most suitable practical technology on the market.
For the future development of the three major trends of driverless, electric vehicles and car networking, Toyota has also started its own pace, and step by step, step by step, and go forward. Toyota has said that the unmanned function of the expressway will be realized by 2020, and the prospects for hydrogen fuel vehicles will continue to be explored in the future.
As for the Internet of Vehicles, as long as Toyota wants to do it, it is not a problem. At the beginning of the year, Toyota has joined the NVIDIA camp, and this also shows that Toyota also hopes to accelerate the pace of development in the field of car networking.
As one of the world's most famous car companies, the future of the global automotive industry naturally has the role of Toyota.
