Bosch technology enables redundancy needed for automated driving

By Zenobia Hegde

Without redundancy, there is no automated driving. The promise of automated driving requires a mix of technological, societal and regulatory development and co-operation. The technology continues to advance thanks to sensors and software, but also thanks to redundancy. In order to realise fully-automated driving on the path to the accident-free future, redundancy in safety-critical systems such as braking and steering is an absolute.

Bosch is actively developing and bringing to market redundant braking solutions to support all levels of automation as defined by SAE. At the 2018 North American International Auto Show, the leading global supplier of technology and services will showcase its braking solutions, including redundant braking for automated driving.

“The importance of redundancy for the rollout of automated driving goes beyond just the technological function as it ultimately will build confidence in consumers as they understand these systems are designed with deep levels of complexity to handle a variety of situations,” said Mike Mansuetti, president of Bosch in North America.

SAE level 3 (conditional automation) vehicles will begin to hit the market as soon as 2018. For these vehicles, a human driver is still necessary, but safety-critical functions may be completely shifted to the vehicle under certain traffic or environmental conditions.

Drivers must still remain present, but will need a certain amount of time to realise that an intervention is necessary. Redundant functions ensure that all safety-critical functions continue during this time span, even in the rare case of a failure in the system. For SAE levels 4 and 5, the redundancy becomes even more critical as the time span increases without the driver in the loop.

Bosch’s solution for a fail-degraded brake system (steering system and EE architecture) is the combination of its electromechanical brake booster iBooster and ESC (Electronic Stability Control), also known as ESP® (electronic stability program), systems. Both are independently capable of performing braking functions for the vehicle in the rare case of a single failure.

The technological breakthrough of redundant braking was achieved by modifying one system element; the vacuum brake booster is replaced by an intelligent electro-mechanical booster, the iBooster. A conventional brake system today comprises two actuators: a vacuum brake booster and ESC unit.

The redundant brake system is comprised of two actuators that are each able to decelerate the vehicle independent of the driver applying the brake pedal. Even if a failure occurs in the brake system, either actuator (iBooster or ESC) is able to avoid wheel lock-up by modulating the brake pressure, which maintains the ability to steer during deceleration.

Bosch’s redundant brake system for automated driving was named a finalist for the 2018 Automotive News PACE (Premier Automotive Suppliers’ Contributions to Excellence) Award, which is acknowledged globally as a prestigious industry benchmark for automotive supplier innovation. Bosch was also honored with an eMove360° Award in the category of Automated Driving for the redundant braking technology.

Redundant steering is also a key technology for automated driving and Bosch is leading in this area. At NAIAS 2017, Bosch introduced its Electric Power Steering (EPS) system with fail-operational function. The system, which enables […]

Senet and Sagemcom partner to demonstrate LoRaWAN geolocation services at CES 2018

By Zenobia Hegde

Senet, a provider of cloud-based software, global connectivity service platforms and network build-out for the Internet of Things (IoT), and Sagemcom, a French group providing high added-value smart terminals market, have partnered to demonstrate LoRaWAN™ geolocation services at CES 2018.

With research indicating that over 50% of the IoT market is best suited to Low Power Wide Area Network (LPWAN) connectivity and a third of the world’s 15 billion connected devices forecasted to be dependent on geodata by 2020, LoRa™ geolocation is well positioned to offer power efficient and cost-effective location capability for a wide range of applications that do not require the precision of GPS.

Sagemcom and Senet are demonstrating LoRaWAN tracking capabilities through the integration of Sagemcom’s geolocation solver software with Senet’s LoRaWAN network. Sagemcom Siconiaä multi-sensor devices have been placed on mobile and stationary assets throughout the Las Vegas area and are reporting geolocation and environmental data over the Senet LoRaWAN network.

Geolocation information is being combined with other readings and visualised in demo applications that illustrate how users across industries can leverage IoT data for asset management, inventory, security and maintenance. Sagemcom is conducting demonstrations in the Venetian, Tech West, Level 3, meeting rooms 3301A/3201B.

“LoRaWAN geolocation brings a strong disruption in the asset management and logistic markets and is a viable commercial technology for a wide variety of IoT applications where GPS is cost and/or battery life prohibitive,” said Eric Rieul, CEO of Sagemcom Energy & Telecom SAS. “Through our tight collaboration with Senet, we are able to rapidly deliver these new features and capabilities to market and successfully drive new business opportunities where the promise of IoT had previously been slowed by cost and scalability challenges.”

“Geolocation is an exciting enhancement to our LoRaWAN connectivity services and opens up new use cases that are expected to drive substantial revenue streams for LoRaWAN network operators and solution providers,” said Dave Kjendal, CTO of Senet. “We are pleased to be partnered with Sagemcom to deliver such high-performance and highly differentiated solutions to the market.”
