Toyota is set to introduce its steer-by-wire technology into production by the end of 2024, and the bZ4X EV SUV and its Lexus counterpart, the RZ, will be the first models to feature this technology. Here's an elaboration of the key information regarding Toyota's steer-by-wire technology:
Steer-by-Wire Advancements
Toyota is preparing to introduce its steer-by-wire technology, known as One Motion Grip, into production by the end of 2024 and this technology eliminates the need for a mechanical link between the steering wheel and the wheels. The significant upgrade to this system involves a new 200-degree steering ratio a notable improvement from the previous 150-degree ratio and this enhancement aims to offer a smoother and more natural steering feel making it more intuitive for drivers to use.
Testing and Feedback
Toyota has taken a meticulous approach to ensure that the enhanced steer-by-wire system delivers a comfortable and familiar driving experience. They have involved a diverse group of participants including both internal teams and external individuals, for extensive testing and the goal is to incorporate user feedback making the technology as user-friendly as possible.
Legislation and Certification
Initially, the implementation of steer-by-wire technology faced legal challenges in different regions. In Europe, a new certification program has been established to accommodate by-wire steering systems, effectively removing the requirement for a mechanical steering linkage. This has made steer-by-wire technology legal in Europe. It is also legal in Japan, while its legal status in the US and the UK remains uncertain.
Over-the-Air Updates
In order to facilitate over-the-air software updates, the steer-by-wire technology is designed to be interoperable. However, existing legislation does not permit remote updates and this feature has the ability to provide flexibility and allow for future improvements and modifications.
Future Developments
Toyota is not stopping at this enhancement. The company is actively working on an advanced version of the steer-by-wire system called Neo Steer and this iteration takes innovation a step further by integrating accelerator and brake controls into the steering wheel. Neo Steer is particularly designed to cater to drivers who are unable to use foot controls. However, the timeline for when Neo Steer will be in production is yet to be determined.
India's EV Plans
In India, Toyota has showcased the bZ4X which is a significant step toward the brand's EV offerings. However, the official plan is to introduce Toyota's first electric vehicle in the Indian market by 2025 and this EV model will be based on the Maruti eVX SUV showcasing Toyota's commitment to the growing Indian EV market.
Conclusion
Toyota's steer-by-wire technology represents an innovation in driving control systems providing a smoother and more natural steering feel and it will be featured in the bZ4X EV SUV and the Lexus RZ enhancing the driving experience in electric vehicles.
