Automotive Electric Power Steering Market: EPA with ADAS Technology Go Hand-in-Hand

Stakeholders in the automotive electric power steering (EPS) landscape are focusing on various technological innovations. The automotive electric power steering market is witnessing significant growth opportunities, as the advanced systems are being incorporated in increasing number of passenger and light commercial vehicles.

As far as commercial vehicles are concerned, stakeholders in the automotive electric power steering business are increasing the use of lightweight, compact, and high-output hydraulic assist power steering gears. Thus, the technology of power steering equipment is leveraged with the help of high-performance brakes and suspensions that enhance control on a vehicle’s behavior. As such, stakeholders are advancing developments to strengthen electronics and electrification technologies in commercial vehicles. Thus, the development of robust electrification products such as electric motors, column assists, EPS with advanced driver assistance systems (ADAS), and autonomous driving products is being increasing witnessed in the automotive electric power steering market.

For instance, in December 2018, Hitachi Automotive Systems, Ltd. a leading manufacturer of automotive components in the automotive electric power steering market, announced the redirection of its commercial vehicle steering trade to Knorr-Bremse - a global market leader for braking systems. This strategic move by Hitachi Automotive Systems, Ltd. was taken to leverage Knorr-Bremse’s steering control technologies and advanced driver assistance systems.

To establish the efficient performance of automotive electric power steering systems, stakeholders in the automotive electric power steering market are trying to closely understand the science of the effects of the weight of a dual-motor full-weight EPS system. This has led to the understanding of fault-tolerant control strategies that stakeholders are likely to adopt. Thus, after comparison between conventional single-weight EPS systems with dual-motor full-weight EPS systems, it has been proven that, full-weight EPS systems enhance vehicle stability control, improve fault-tolerance performance, and make vehicle driving much easier.

As such, stakeholders and car manufacturers in the automotive electric power steering market are increasingly using advanced driver assistance systems and automated driving (AD) technology in full-size vehicles. Since full-size vehicles are equipped with more than 12 volts of power supply, there is an increased demand for electric power steering systems. Thus, in order to leverage the functionality of electric power steering systems, stakeholders in the automotive electric power steering market are backing EPS systems with hydraulic power steering technology. Since hydraulic power steering systems are challenged with electric power shortage, an auxiliary power supply system using lithium-ion capacitors are being used to overcome the same.

Differential Braking Technology to Overcome Weight, Cost, and Complexity Limitations

To overcome the technological limitations, manufacturers operating in the automotive electric power steering market are doubling up on critical components. However, doubling the critical components to develop fail-safe operations of electric power steering systems adds additional weight, cost, and complexity to these systems. As such, stakeholders are overcoming these limitations with the help of differential braking technology. Differential braking helps turn the vehicle in the desired path by applying brakes on the inside wheels. Thus, car manufacturers are increasingly using differential braking technology in self driving vehicles.

Likewise, car owners of the newer versions of Honda Civic and Accord have encountered technological issues such as disorderly functioning of EPS systems. In many cases, the car’s power steering stopped functioning without any warning, due to which, the owners faced difficulty in turning, and some individuals encountered the disorderly lighting up of the lights of the EPS dashboard. Thus, stakeholders are conducting rigorous research & development to overcome such technological issues in EPS systems.
