Nexteer and Continental Joint Venture CNXMotion Expands Brake-to-Steer Technology with New Software Functions
PR96174
GRAND BLANC, Mich., May 24, 2022 /PRNewswire=KYODO JBN/ --
-Flexible, Cost-Efficient Software Functions Enhance Safety Redundancies for
EPS & SbW Systems
Further leveraging technology building blocks from its parent companies,
Nexteer Automotive and Continental Automotive, CNXMotion expands its
Brake-to-Steer (BtS) technology with two new software functions that provide
backup safety layers for all variants of Electric Power Steering (EPS) and
Steer-by-Wire (SbW) systems and across all SAE levels of driving automation
(levels 1 – 5).
CNXMotion's BtS technology portfolio includes:
-Driver Effort Support: SAE Levels 1-3 – NEW
-Steer-by-Wire Support: SAE Levels 1-5 – NEW
-Automated Driving Support: SAE Levels 4-5 (launched in 2020)
"These new Brake-to-Steer software functions further enable safety redundancies
across all electric power steering applications and SAE driving levels without
the cost and complexity of additional hardware," said Greg Katch, General
Manager, CNXMotion. "Our advanced Brake-to-Steer technology can help ensure the
safety net is always on through driver effort support and steer-by-wire
support, as well as automated driving support."
Brake-to-Steer Driver Effort Support
EPS systems are designed with multiple protective layers to ensure the steering
safety net is always on. When paired with a traditional EPS system, BtS Driver
Effort Support adds another safety layer and can provide up to an additional
25% reduction in torque. While steering traditionally manages the lateral
control of a vehicle, BtS enables the braking and powertrain systems to
contribute to lateral control to reduce steering efforts when necessary.
Brake-to-Steer Steer-by-Wire Support
SbW replaces the mechanical steering connection between the hand wheel and road
wheels with algorithms, electronics and actuators. In this type of steering
system, the BtS SbW Support function adds another safety layer by translating
the driver's steering inputs into brake system control of the vehicle's lateral
motion.
Brake-to-Steer Automated Driving Support
Launched in 2020 (
CNXMotion's original BtS function pioneered the use of electronic braking as an
additional layer of steering control for traditional, highly automated and
autonomous vehicles (SAE Levels 4–5). This BtS function earned an Automotive
News PACEpilot Innovation to Watch in 2021.
"Brake-to-Steer's expanded software functions highlight how collaboration
through our CNXMotion joint venture with Continental leads to innovation in
motion control solutions and further enhances the steering safety net for all
assisted and automated driving levels," said Robin Milavec, President, Chief
Technology Officer (CTO), Chief Strategy Officer (CSO) and Executive Board
Director, Nexteer Automotive. "When combined with Nexteer's industry-leading,
advanced steering systems like Steer-by-Wire or High Availability EPS,
Brake-to-Steer provides OEMs with a cost-efficient, flexible way to add yet
another layer of safety and redundancy."
Brake-to-Steer Benefits for Drivers & OEMs:
Value: Leverages the vehicle's existing steering, braking and powertrain
systems. The portable software functions can reside on an existing controller –
eliminating the cost of any additional hardware.
Flexibility: Provides an additional layer of vehicle safety and redundancy on
all vehicles with EPS and SbW. The three BtS software functions cover all types
of vehicles with or without a driver.
Safety: Enhances safety through an additional layer of steering redundancy.
"As the industry progresses toward highly automated and autonomous vehicles,
Brake-to-Steer's advanced functions allow for critical safety features across
all levels, enabling increased safety for all road users," said Lutz Kuehnke,
Head of Safety and Motion Business Area, Continental Automotive, North
America. "CNXMotion's Brake-to-steer technology offers a flexible and
cost-effective way to achieve and to prioritize safety needs by leveraging
existing systems in the vehicle, e.g. Continental's 1-box brake controls unit
MKC1, and eliminating the need for additional components.
