LIDAR (a combination of light and radar) is an indispensable component of many autonomous vehicles. It measures distance through light and becomes the eyes of autonomous vehicles.
Light Detection and Ranging is abbreviated as LiDAR or laser radar. It is an optical remote sensing technology that uses light to measure the distance of a target. LiDAR can measure the distance with high precision, recognize the appearance of objects, and build a 3D geographic information model around it. The advantages of distance measurement, high precision, and high recognition etc., are not affected by the brightness of the environment. It can sense the shape and distance of surrounding obstacles day and night. The scanning range is 100-200 meters, which can meet the needs of self-driving cars’ more precise sensing needs.
With the constant development of modern technology, the power output of equipment, such as internal combustion engines and motors is getting stronger and stronger. To attain the full efficiency of these power sources, reducers are incorporated.
In 2021, the global electric vehicle market will grow by 40%, with total sales exceeding 3 million units. As of 2019, more than 2 million electric vehicles have been sold worldwide, accounting for 2.5% of all vehicle sales. It is estimated that the compound annual growth rate of global electric vehicles in the next ten years will reach 29%; the total sales of electric vehicles It will increase from 2.5 million in 2020 to 11.2 million in 2025 and 31.1 million in 2030.
At present, ordinary automobiles mainly use fossil fuels as their power source, which not only consumes a lot of petroleum resources but is also one of the main culprits of greenhouse gas emissions. In order to cope with the global trend of energy-saving and carbon reduction, many countries have adopted vehicle electrification as an important greenhouse gas reduction measure.
The World Steel Association predicts that after a slight decline in steel demand in 2020, steel demand in 2021 will increase by 5.8% to 1.87 billion metric tons. The rebound in demand from the automotive industry is the main factor driving the growth of the steel market.
