Nexteer and Continental Joint Venture CNXMotion Develops Brake-to-Steer Technology
AUBURN HILLS, Mich., Dec. 3, 2020 /PRNewswire-AsiaNet/ --

Enhances the Steering "Safety Net" in Highly Automated Driving

- Pioneers use of electronic braking as an additional layer of steering control 
for traditional, highly automated & autonomous vehicles (Automation Levels 1 - 
- Offers a cost-effective approach to achieve advanced safety 
- Leverages technology building blocks from parent companies: Nexteer 
Automotive and Continental

Leveraging technology building blocks from its parent companies Nexteer 
Automotive and Continental, CNXMotion announces Brake-to-Steer (BtS) - a 
technology that provides driver safety through an additional layer of 
directional control for highly automated and autonomous vehicles. 

In highly automated vehicle applications, steering systems feature multiple 
protective layers to ensure the steering safety net is always on. In addition, 
BtS adds yet another layer by using the electronic brake system to safely steer 
the vehicle while simultaneously controlling its speed. In a fully autonomous 
vehicle with no steering wheel present, BtS will negotiate a commanded path 
until a safe pull-over can be achieved.

"Perhaps the most critical challenge in highly automated and autonomous driving 
is ensuring the robustness of system redundancies to keep drivers, passengers 
and road users safe," explained Alan Davis, general manager of CNXMotion. 
"CNXMotion's Brake-to-Steer technology offers another steering safety layer for 
a wide range of automated driving conditions."

CNXMotion's BtS technology offers a cost-effective way for automakers to 
achieve safety needs by leveraging the vehicle's existing braking and steering 

"As we progress toward higher levels of automation in vehicles, secondary and 
tertiary redundancy becomes crucial in executing successful minimum risk 
maneuvers. This helps keep vehicle occupants and road users safe," said Hiren 
Desai, Head of Strategy, Autonomous Mobility and Safety, Continental North 
America. "Cross-domain functionalities such as Brake-to-Steer are enabled by, 
and housed on, existing hardware, like Continental's MKCx brake-by-wire 
systems, eliminating the need for additional, costly components."

"While steering traditionally manages the lateral control of a vehicle, 
Brake-to-Steer enables braking to contribute to lateral control as well," said 
Robin Milavec, Senior Vice President, Executive Board Director, Chief 
Technology Officer (CTO) and Chief Strategy Officer (CSO), Nexteer Automotive. 
"When combined with advanced steering systems like Nexteer's High Availability 
Electric Power Steering or Steer-by-Wire, Brake-to-Steer gives an additional 
layer of redundancy - further enhancing the safety net."

How Brake-to-Steer Works 

The BtS function resides in the Motion Control System (MCS), which acts as an 
intermediary between the vehicle's path planner (the automated driving system) 
and the actuators (steering, brakes and powertrain) to determine the best path 

Integrated with a Performance Manager, the vehicle's intended path is compared 
to the system's ability to steer the vehicle via BtS, while constantly 
negotiating the safest route ahead. 

In the event that BtS needs to engage, BtS reacts in one of three ways:  

1. Continues on the intended path before ultimately moving to the first or 
second option, 
2. Performs a minimum risk maneuver, such as slowing and braking to steer the 
vehicle to the side of the road, or 
3. Stops in the lane. 

Originally developed for steering redundancy in Level 4+ autonomy, the feature 
can be adapted to assist a driver in multiple scenarios for lower levels (Lane 
Keep, Obstacle Avoidance, etc.) while a driver is still present, following the 
intentions provided from the driver's steering input.
