Market Trends of South Africa Electric Power Steering Industry
This section covers the major market trends shaping the South Africa Electric Power Steering Market according to our research experts:
ECU is the fastest-growing component amongst all Electric Power Steering (EPS) components
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 Steering 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 algorithm that enables the control of 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 a slower pace. 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.
Government Initiatives and Growing Emphasis on Safer Automotive Systems are Driving the Market
On an average, globally, about 1.24 million people die in road accidents each year, half of whom are vulnerable road users, such as pedestrians and motorcyclists, while the other half die because of side-impact accidents. According to the World Health Organization (WHO), 80% of cars sold in the world are not compliant with the primary safety standards. Only 40 countries have adopted the full set of the seven most essential regulations for car safety.
A significant increase in the number of accidents has also encouraged end-users to adopt better safety systems. Improvements in roadway and motor vehicle designs have steadily reduced injury and death rates in all first-world countries. However, the accident rates are still higher in some developing countries, and governments are focusing on implementing stringent safety norms and supporting the adoption of various subsystems in the vehicles.
Driven by these factors, automobile manufacturers are incorporating several systems in vehicles that enhance safety. Advanced safety and security features are no longer restricted to premium vehicles. Consumers are now more concerned about safety systems and technologies, and therefore, they are more interested in opting for cars that are equipped with better safety systems.
Moreover, the stringency in government regulations regarding fuel efficiency and safety initiatives are essential drivers for the growth and development of the advanced steering systems that comprehensively employ steering sensors.
