Link Manufacturing is beefing up its usage of digital technologies with an upgraded Cabmate, unveiling a cab suspension system that smooths the ride for both drivers and those in sleepers. Link's Road Optimized Innovations (ROI) system uses sensors and an electronic control unit (ECU) to stabilize the entire cab for roughly the cost of two advanced comfort seats.

Engineers push engine, transmission technologies to turn off fuel usage.

Commercial-truck powertrains are doing more with less. Engine developers are adding features that reduce fuel consumption, saving owners money while helping fleets reduce emissions. Digital technologies continue to transform commercial trucking as powertrain providers devise new ways to eke more from each drop of fuel. Engines now adapt to road conditions, adjusting power and shutting down some or all of the cylinders as demands change.

Biometric technology is deemed essential to ensuring AV driving safety and advancing the user experience-if privacy issues don't derail its deployment.

Research into potential automotive applications for biometrics-facial and retina scans or fingerprints-is increasing, despite rising concerns about privacy and data security, and outcries from civil liberties advocates. A growing number of OEMs, Tier 1s and startups are striving to add facial recognition capability to driver monitoring systems (DMS).

The challenges are myriad, but automated-trucking developer TUSimple believes the efficiencies of true depot-to-depot driverless hauling are too promising to ignore.

The developers who are creating autonomous systems have plenty of complex technical questions that must be analyzed and solved, but their challenges don't stop there. Design teams also have to plan for the use cases of driverless vehicles, even going so far as to plan for what might happen if the vehicle has to sacrifice itself to avoid a serious accident.

Scalable, cloud-based architectures are gaining greater acceptance for simulating and testing the myriad development aspects of automated driving.

As the auto industry strives to improve safety and edge towards high-level automated driving, the complexity of proving that electronic vehicle controls will perform safely is skyrocketing. Simulation's expanding role in systems validation is prompting many tool providers to move to scalable, cloud-based architectures that run operations in parallel to shorten analysis times.

Autonomous developers at TuSimple address many technical issues, but they also must consider regulations and operating modes.

The developers who are creating autonomous systems have plenty of complex technical questions that must be analyzed and solved, but their challenges don't stop there. Design teams also have to plan for the use cases of driverless vehicles, even going so far as to plan for what might happen if the vehicle has to sacrifice itself to avoid a serious accident.
