Sony develops self-driving car sensor that saves 70% of energy

Sony is planning to develop a new type of autonomous vehicle sensor, capable of saving more than 70% of energy, helping to reduce consumption and extend the operating range of electric vehicles.

Accordingly, the new sensor developed by Sony Semiconductor Solutions will be integrated with the software of the Tier IV startup, aiming to cut the power consumption of boards used in electric vehicles (EVs) by 70%.

Without stopping, the two companies expect to achieve Level 4 technology for integration in self-driving cars under certain conditions by 2030.

Boston Consulting Group predicts electric vehicles will account for 59% of global vehicle sales by 2035. More than 30% of trips 5km or more will be made by self-driving vehicles, which use the same number of vehicles. large number of sensors and cameras and transmit huge amounts of data.

Existing self-driving systems are said to use as much energy as thousands of microwave ovens combined, an obstacle to expanding the range of these vehicles.

According to Japan’s Ministry of Economy, Trade and Industry, if you calculate the total consumption from the air conditioner and other functions on the car, EVs can only achieve a distance of 35% shorter than on paper. Meanwhile, if successful, Sony’s new sensor could limit this impact to about 10%.

To achieve this goal, Sony applies edge-computing technology, enhancing data processing capabilities as much as possible with sensors and integrated AI software instead of transmitting data out to the network. outside. In addition, this approach will also limit communication delays and make vehicles safer in traffic.

In addition, the Japanese corporation also incorporates radar technology, image recognition into the new sensor so that EV vehicles can drive themselves even in the rain or in other extreme conditions.

Sony controls nearly half of the global image sensor market and aims to be a partner with 75% of the world’s major automakers by 2025.

Meanwhile, Tier IV is an open source self-driving software provider used by Yamaha Motor and Foxconn. The company plans to work with Sony to develop basic self-driving technology for use both at home and abroad.

Self-driving vehicles are starting to appear more and more on the streets with self-driving taxi services of Waymo (under Alphabet), Cruise (General Motors) in the US or Baidu in China. However, currently, energy saving solutions for EV vehicles have not been focused. Instead, automakers are still mainly looking for ways to increase battery capacity to meet the needs of the vehicle’s system.
