Juice Gets ISO/SAE Cert
Juice Technology leader in mobile charging stations for electric vehicles, receives proof of risk management in product development with international certification in accordance with ISO 21434.
The ISO/SAE 21434 standard was published in August 2021 and relates to components, spare parts and accessories for production vehicles. It covers all phases in the life cycle of a vehicle – from development through production, operation and maintenance to recycling. Although infrastructure outside the vehicle is not actually covered by the standard, charging infrastructure, as an inextricably linked part of e-vehicle infrastructure, is directly affected by it.
Sensata’s New Brake Pedal Force Sensor for EMBs
Sensata Technologies, announced its new Brake Pedal Force Sensor for electromechanical brakes (EMBs) that enables safer and better performing braking systems.
Automotive electrification and autonomy are powering the trend toward electro-mechanical brakes in next generation cars, especially in hybrid and electric vehicles (EVs). As electronics replace legacy hydraulic components in brake-by-wire systems, there is a need for new sensing topologies in the pedal assemblies. This trend, combined with stricter demands for functional safety, is leading vehicle and brake system manufacturers to consider different brake sensing technologies that ensure EMBs maintain or exceed the performance and safety of legacy systems.
Sensata’s micro strain gauge Brake Pedal Force sensor supports the future of braking. Implementing this sensor enables the reduction in a vehicle’s stopping distance compared to existing technologies. It improves braking by accurately and rapidly capturing a driver’s braking intent.
Able to withstand forces up to 600N (scalable to other forces as well), Sensata’s brake pedal force sensor meets functional safety requirements up to ASIL C, and can operate at temperatures up to 140°C. The compact design, flexible integration options and variety of outputs allow engineers to easily customize the sensor for their application.
The new Brake Pedal Force sensor offers several advantages compared to traditional pressure and/or position sensing technologies including:
- Enables accurate, robust, and fast driver intent measurement in Brake-by-Wire e-Pedals with zero or limited movement
- Improves response time by more than 10ms, reducing braking distance
- Detects mechanical failure of the system due to a stuck pedal
- Supports hydraulic, electro-hydraulic and brake-by-wire braking architectures
Veoneer & Arbe to Co-Develop Radars
The automotive technology company Veoneer and the 4D imaging radar solutions company Arbe Robotics Ltd (Nasdaq: ARBE) have announced plans to co-develop radars for automotive-grade safety and rolling out autonomous functionality.
After 5 years extensive research among technology start-ups, Veoneer has chosen to partner with Arbe for their 2K high resolution industry-leading surround radar, able to enhance the perception system and sensor fusion.
Veoneer will develop, market, and integrate two surround 4D imaging radars extending on Arbe’s reference designs: one long-range, high resolution, 360° sensing solution with 48×48 RF channels (Tx/Rx) and one with 24×12 RF channels. Veoneer’s patented waveguide technology will enhance Arbe’s performance metrics further by improving antenna efficiency and reducing performance variability in the manufacturing process.
The 4D ultra high-resolution imaging radar operates also in difficult weather and lighting conditions and it differentiates true threats from false alarms to ensure a safe road ahead for drivers, pedestrians, and other vulnerable road users. The radar sensor is modular in design, reliable and affordable, providing both redundancy and the data diversity that is critical for both automotive-grade safety and rolling out autonomous functionality.
The new surround radar is expected to be in pre-production by mid-2023.
xEV Semiconductor Demand Forcecast
The push to electric vehicles is being dictated by consumer awareness and government regulations and mandates related to climate change and the need to reduce emissions and reverse the impacts of global warming. The latest Strategy Analytics Electric Vehicles Service (EVS) report, “xEV Semiconductor Demand Outlook 2021-2029” forecasts that electric vehicle production will grow at a CAAGR (compound annual average growth rate) of 26% over 2021 to 2026, with volumes approaching 54.1 million units by 2029. This in turn will drive demand for corresponding xEV powertrain semiconductors which is forecast to grow at a CAAGR of 31% and reach $27.3 billion by 2029.
Semiconductor demand from xEV powertrain systems covered in this analysis include the key systems necessary for operation of mild hybrid, full hybrid, plug-in hybrid, and battery electric powertrains. This includes battery management systems, DC/DC converters, main traction inverter, electric motor, and onboard charger. Battery electric vehicles will comprise the largest market for semiconductors growing at a CAAGR of 39% and account for 82% of the total electric vehicle powertrain semiconductor market opportunity in 2029.
“Semiconductors required for power electronics will comprise the largest market, with growth accelerating in line with the push towards battery electric vehicles and the move towards higher performing, more efficient wide bandgap semiconductors,” noted Asif Anwar, Executive Director at Strategy Analytics. “This will translate to the market for SiC (silicon carbide) growing at a CAAGR of 39% over 2021 to 2026 and grow through 2029 to reach $8.3 billion at which point we will have reached a tipping point with SiC semiconductor demand exceeding that of Si (silicon) power semiconductors.”
