Automotive Electric Power Steering ECU Market is anticipated to register a CAGR greater than 6.95% during the forecast period (2020 – 2025).
Automotive Electric Power Steering ECU is an integral component that is needed to drive the electric motor in the EPS unit. Factors such as extensive ownership of personal vehicles and growing technological advancements will see the rise of the EPS ECU market.
The rising popularity of self-driving vehicles is fueling the demand growth in the electric power steering system market and the ECU across the world. Vehicles that are equipped with EPS tend to have a reduced overall weight, which further increases fuel efficiency.
China and India are leading the markets due to growing affordability and seeing a rise in personal automotive ownership . Other emerging markets also include South East Asian Countries like Bangladesh and Vietnam, which also saw positive growth. In India, government policies such as 'Make in India' initiative to improve the manufacturing sector in the nation, will also see a bright future for the EPS ECU market.
Key Market Trends
Rising Demand for Electric Power Steering (EPS) ECU
The electric ECU provides a lower cogging torque for the better driving experience, improving the interaction between the permanent magnets of the rotor and the stator slots of the Permanent Magnet (PM) machine. Traditional steering systems required the driver to continually make minor steering corrections to compensate for irregularities, such as road camber or crosswinds. But modern Electric Power Steerings automatically assists the driver in case they encounter such barriers. The ECU unit can register if the driver is continuously counter steering, and itself automatically compensate for the correction. This makes driving more comfortable and less stressful.
ECU consists of 3 significant components that are the control module, power module, and control software. The control module gives access to power the switches and performs diagnostics functions in the power module. While the power module consists of three half-bridges where each half-bridge powers one phase of the three-phase electric. Lastly, the control software is the algorithms that enable to control the speed and torque of the electric of the EPS unit. However, designers face challenges such as meeting flexible but a cost-effective architecture that can be equipped in cars ranging from SUVs to compact vehicles by satisfying power requirements for different steering rack load.
However, there is a demand for higher steering power, to improve driver comfort and feedback without losing power assistance, especially at the slower speed. For instance, Nexteer uses three different sensor technologies. While each can be used with the same position sensor, torque sensor, and ECU. The company has introduced solutions that reduce the steering angle sensor, which provides active lighting, stability control, and ADAS. They will enable us to broadcast an absolute steering position based just on the EPS motor sensor.
The Asia-Pacific Will Dominate the ECU Market
The Asia-Pacific APS market is primarily driven by growing vehicle production and sales. To meet government safety standards and emission norms, technological advancements are being made to the ECU segment.
India is an emerging economy where Electric Power Steering (EPS) implementation in passenger cars is overgrowing, owing to its advantages, such as no hoses or fluids required in the steering system, thereby, reducing the repair and maintenance costs.
However, in India, for every minute, a serious road accident occurs, and 16 die every hour. Electric Power Steering significantly makes driving safer. Companies such as Infiniti Q50 incorporated adaptive steering in vehicles whose sensors continuously monitor the position of the steering wheel. Also, these torque ECU sensors are integrated into the EPS system. The torque sensors measure the effort applied by the driver to steer the vehicle.
Currently, less than 40% of the passenger cars are running with EPS technology. Although stringent government regulations regarding fuel efficiency will drive the growth of the segment for the ECU segment. In 2019, the Indian government modified the tax reforms gasoline, diesel, and hybrid cars to promote sales for automobiles.
The Automotive Power Steering ECU Market is consolidated with existing market players such as JTEKT, NSK Ltd., ZF TRW, Nexteer Automotive, Rane Group, and Sono Koyo Steering which hold the most significant shares. To have the edge over its competitors' companies are making joint-ventures, partnerships, launching new products with advanced technology.
For instance, In 2018, Datsun India launched newer models of Datsun GO and GO+, which are equipped with a speed-sensitive ECU system. Tata has launched the Nexon HyprDrive Shelf-Shift Gears model, which features automated manual transmission ECU technology.
