Light is amounted to (the technology that LiDAR) technology is making investment group and automobile industry is bestowed favor on newly.
Facilitate the reason of this one trend has 2. It is the technical foreground that amounts to a technology to have not finalize the design finally solely firstly. Technology of é Veloppement of Yole D of city air company and market analyst Alexis Debray think, light amounts to a technology " had not developed maturity. We are in those who embrace light to amount to gigantic revolution to begin at present. We are in those who embrace light to amount to gigantic revolution to begin at present..
Another element depends on the concept that this accepts extensively: Light is amounted to is to drive automatically taxi (the technology with necessary Robo-taxis) . Yole points out, waymo, Uber, Lyft, Baidu (Baidu) and run quickly (the company such as Mercedes-Benz) begins will " every average value the sensor of 200 thousand dollar (include to be amounted to solely) conformity arrives in hundreds traditional car " , it is with changing one's costume or dress its can be in the city is street of movement drive completely automatically car.
There are all sorts of latest newses about amounting to application solely on media. But this kind report did not discuss all sorts of techniques in conformity of the place in be not being amounted to with type light respectively normally. Below the assistance of Yole, " EE Times " potential of the actor defect that labor differs to amount to a technology solely, its market, and the light that makes investment target central point amounts to a supplier to show besides.
Light amounts to the main participator of the market
Yole thinks, light amounts to main root to result from two technologies -- come from a number to photograph firstly, another is Lei She range finder. Debray points out, as a result of " mix these two kinds of technologies in the product " , what the part explained light is amounted to is complex spend and diversity.
broad sense, car domain uses the light of two kinds of types to amount to. "Industrial level " light is amounted to use at driving automatically taxi. Another kind of Debray is so called " the car uses level " light is amounted to, will be driven automatically by what deploy consumes the market at the masses car. Stage light amounts to industry to be defined to be " the durability that has 24 hours to use, Gao Lingmin is spent and high-powered " . Current, because light is amounted to,basically serve as industry / commercial application, cost is not main problem. Its price is very high.
By comparison, when should involving the car that predicts to be used at public marketplace car to be amounted to with stage light, OEM will begin to haggle over every ounce to each respect such as interface exterior from the price, dimension.
According to different scanning technique approach, yole amounts to light differentiate it is 5 kinds: Much channel grand machinery scans (wait for) like Velodyne, Valeo; Other machinery scans (wait for) like Luminar, Panasonic; MEMS light is amounted to (wait for) like Leddar Tech, Innoviz, Pioneer; Optical photograph accuses array radar (like Quanergy, Robosense) ; And flashy (Flash) light is amounted to (wait for) like Argo, Sense Photonics, Continental.
The design is amounted to in all sorts of light in, grand machinery scans is to use most technology at present. These light are amounted to already usable, and also be designed at driving automatically in the car, having a test at present, preparative application drives automatically at commerce taxi business. But these light are amounted to still do not perfect really. Debray says, "They are very costly still -- must cost several dollars, and volume is very huge. And volume is very huge..
MEMS light amounts to the next be consideringed as most potential technology. Debray explanation says, it is euqally good that its function and tiny mechanical light are amounted to, and because use less part and may further narrow measure and become cheaper. This year in April, the light that BMW announces plan general Innvoiz amounts to application to drive automatically at its car.
The light that Yole learns use light to control array is amounted to (the product that offers like Quanergy) regard as " after MEMS scanner next " . Because need not use mobile component, what can do consequently is smaller, cheaper.
The company such as Continental and Xenomatix put forward to flash light is amounted to, it can enlighten at the same time whole setting, and need not use mobile component. According to Debray observation, flashy light is amounted to make a likelihood simpler, but its feeling measures range relatively MEMS light amounts to a little bit smaller.
Yole listed a few other firms that offer different solution, if Cepton and Luminar use mechanical scanning technology, Neptec,use prism. But Debray says, because lack the detail of these technologies, still evaluate very hard at present.
Wavelengh is crucial
Current, most car consumed is amounted to through blast off about the Lei She of 900nm wavelengh shoots pulse, scanning surroundings, record reflex line, in order to build the dot cloud of map car surroundings (Point Cloud) .
The Lei Shean according to the United States and other country is completely regular (power of limitative laser pulse, because it can harm person eye) , the cannon-shot that requirement light amounts to is confined to 30 to 40 meters. This jockeys in the safety when high speed travel to car for the distance too short. Drive automatically the car must be in distance at least 200 meters are far the object that discovers low reflectivity before, it is dangerous to have so that allow a car,enough time differentiates jockey.
However, a few companies begin exploration to use recently 1, 550nm wavelengh, this makes them OK use higher Lei She power, and unapt harm is retinal. According to Debray, the cannon-shot that higher power can expand long wave light is amounted to and resolution. He points out, the company such as Blackmore, Neptec, Aeye and Luminar begins to use 1, 550nm wavelengh.
Nevertheless, debray explanation, among them a defect is, use 1, the amounts to place to need solely Lei She of 550nm and photoelectricity detector do not resemble 900nm advanced in that way, limitted the choice that amounts to a supplier solely consequently.
Pulse and successive wave
If you use all sorts of scanning methods,undertake classified to be being amounted to solely as X axis, so the different method that is used at projectile on the object light made Y rod.
Light amounts to current great majority to be used those who call pulse light to amount to is direct (Direct) light is amounted to. They give out a smooth pulse to the target, affirm a distance by the time that returns smooth detector, debray explains.
"Method of successive wave range finding " it is new occurrence method. Some companies begin to use symbolic wave -- or say " sine wave " -- pulse of and rather than, bring better sensitivity according to saying to be able to be amounted to for light. Debray points out, this is a kind of technology that has perspective, but it needs smooth unisonant sex. IFM and Benewake are studying phase shift method.
In the meantime, blackmore and Oryx begin to study method of frequency modulation range finding. Debray says, it is moved to become successive by described as frequency wave (Frequency Modulated Continuous Wave; FMCW) , allow heterodyne to explore, "What in resembling radio, use " , can bring taller than detecting directly sensitivity.
The future that amounts to solely
Debray thinks, without a kind of any technologies the breakthrough can reduce the door that amounts to true predominate technology solely to pit. He says, the key of this one wrestle depends on if where,amounting to developer solely obtain between different technique and market demand balanced.
But still a more extensive question deserves a consideration. While car consumed amounts to a technology to develop ceaselessly, advanced drive support system (ADAS) and drive automatically the other sensor technology that uses in the car also is in progress. For example, che Yonglei amounts to into use beam is controlled and become better and better like ability. No less, the visual processor that ties AI also is in in be being perfected ceaselessly. This will conduce to camera detects and classify an object, make its understand 3D space effectively.
Anyhow, do not have in car domain sensor must be installed about what in ADAS or drive automatically the agreement of the car. Debray says, "For example, tesla (Tesla) does not make consumed is amounted to. " the Kaidilake that publishs at the beginning of this year (Cadillac) nobody drive cruise system Super Cruise also did not use light to amount to. Contrarily, it depends on a map greatly.
On the other hand, for example Ao Di (the light of Audi) use Valeo is amounted to, and BMW just announces to plan to use Innoviz light to amount to.
Drive automatically besides what had installed light to amount to taxi, does the car of public marketplace car amount to market dimensions to will have with stage light how old? As the progress of time, will market opportunity narrow gradually?
The Debray of Yole says, still cannot make any conclusion now. Decide what technology will be used generally at driving automatically in the car, return premature at present. Nevertheless, he complements, ADAS car and drive automatically car " will need sensor between redundant " , ability develops its latent capacity.
Yole estimation, 2017, the design amounts to market dimensions to be 107 million dollar with the light at ADAS car, and use at driving automatically the light of car is amounted to it is 220 million dollar. To 2023, the light of ADAS amounts to the market to predict to will reach 1.7 billion dollar, and drive automatically the light of car amounts to the market to have 3.5 billion dollar about.
Notable is: Industry amounts to investment pace of the technology to be being accelerated to light. A lot of person that start line of business of enterprise, a gleam of newly and OEM use the light of different method to amount to in development, but these methods can not assure to succeed certainly. Debray says, everybody is going after ascend body " the car amounts to technical mart with stage light partially " dream.
According to Yole estimation, be in only go two years (2016-2017 year) , "The capital that invest in light amounts to a company exceeded 800 million dollar " .
Below the help of Yole, the light that this print arranged 15 months to obtain more than 5 million dollar to invest amounts to company list (arrange) alphabetically.
