<\/p>\nSchaeffler is embarking on a development partnership with Robert Bosch Automotive Steering GmbH to expand its intelligent Rear Wheel Steering (iRWS) portfolio.<\/p>\n
It hopes the partnership will help grow the market by offering integrated solutions for Rear Wheel Steering systems. Under the partnership, Schaeffler is providing mechatronic iRWS systems, and Bosch Automotive Steering is contributing software and electronics in the form of steering control units.<\/p>\n
<\/p>\n
\u201cCombining the strengths of both companies enables us to create integrated systems that deliver superior added value to our customers,\u201d commented Matthias Zink, CEO automotive OEM at Schaeffler. \u201cIntelligent Rear Wheel Steering technology is a key milestone in Schaeffler\u2019s journey to becoming the technology partner of choice for chassis systems.\u201d<\/p>\n
Schaeffler successfully launched its mechatronic intelligent Active Roll Control system (iARC) back in 2015.<\/p>\n
\u201cThe lessons we learned from that process flowed directly into the development of mechatronic Rear Wheel Steering\u201d, said Dr. Keiwan Kashi, president business unit mechatronic systems at Schaeffler. \u201cBy combining our expertise in mechatronics with our core competencies in the industrialization of mechanical and mechatronic components, we created a highly efficient product that can be tailored to customer requirements.\u201d<\/p>\n
The mechatronic iRWS unit improves ride comfort and safety which offers several key benefits in today\u2019s rapidly urbanizing world. By turning the rear wheels in the opposite direction to the front wheels, it reduces the turning radius, significantly increasing maneuverability in tight spaces, such as when parking in busy urban settings. Moreover, the rear axle\u2019s assistive steering action enhances handling, stability and ride comfort and improves vehicle safety. Schaeffler\u2019s Rear-Wheel Steering system uses lightweight technologies and features a maximum overall weight of just 8kg.<\/p>\n
At the heart of the system is a planetary roller gear that performs a self-locking function, ensuring that the rear wheels do not change direction without steering input from the driver. The planetary screw drive also delivers superior efficiency. Moreover, the system\u2019s design is acoustically optimised, making it particularly well suited for use in low-noise electric vehicles.<\/p>\n
Bosch\u2019s contribution to the partnership is the steering control unit, an integrated module comprising control electronics, an electric motor and software. Scalable and modular in design, this unit is fundamental to many of the driver-assistance functions in Schaeffler\u2019s new rear-axle steering system. Already a proven performer, the steering control unit has been successfully implemented in millions of front-axle steered vehicles. It features Bosch security for robust protection against cyber attacks. Functions and updates are supported by over-the-air (OTA) technology.<\/p>\n
\u201cOur third-generation steering control unit was launched just last year and is already doing very well in the market for front-axle steering control systems,\u201d said Dr. Stefan Waschul, head of passenger car steering systems at Robert Bosch Automotive Steering. \u201cUnder this partnership, we will apply our expertise in this area to rear-axle steering systems and contribute the wealth of experience and technical know-how in software and E\/E architecture that has made us the market leader in steering control systems.\u201d<\/p>\n With decades of experience in software development and steering control, Bosch has already successfully partnered this technology in numerous customer applications. Based on signals from the steering wheel torque sensor, the steering control unit\u2019s integrated electronic controller calculates the optimal steering assist, which is then delivered by the integrated electric motor. In addition to the torque applied to the steering wheel by the driver, the calculation takes into account numerous other vehicle parametres.<\/p>\n","protected":false},"excerpt":{"rendered":" Schaeffler is embarking on a development partnership with Robert Bosch Automotive Steering GmbH to expand its intelligent Rear Wheel Steering (iRWS) portfolio.<\/p>\n","protected":false},"author":3160,"featured_media":23657,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1,20],"tags":[],"class_list":["post-23655","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","category-steering-parts"],"yoast_head":"\n![\"\"](\"http:\/\/www.factorfocus.ie\/wp-content\/uploads\/2020\/09\/Kooperation_iRWS_0018C87D.jpg\")
