Automotive
A published application infers how far the steering rack actually moved from the motor's own electrical behaviour, compares it to the designed ratio, and treats the shortfall as degradation.
Automotive
A Toyota application published July 16 describes a double-sided solid-state cell in which one electrode's solid-electrolyte content varies through its own thickness — electrolyte-rich where it meets the separator, electrolyte-poor where it meets the current collector.
Autonomous Driving
A newly issued patent describes reading traffic signs from a single fused camera-radar tensor built in a shared ground-plane coordinate system, rather than merging two separate detectors after the fact.
Vehicle Systems
A newly published Hyundai application describes a charging-management system in which a stranded electric vehicle asks a server for power, and the server dispatches the nearest suitably equipped EV to come and deliver it. The engineering is in the matchmaking and the protocol layer, not the cable.
Autonomous Driving
An issued Toyota patent draws a formal line between remote assistance and remote driving, gating the choice on whether the car is inside its permitted autonomous-driving domain — speed, map coverage, and weather.
Vehicle Systems
A newly published Hyundai application describes a vehicle that camera-locates a person standing outside, cracks a window just far enough to keep noise down, and electronically steers an array of microphones at the speaker's head so the car can hear them. It is a clean look at how perception, acoustics, and window mechanics get fused into one conversation.

Long before a formal recall, automakers must hand NHTSA a stream of warranty claims, field reports, and death-and-injury data. The mechanism is Early Warning Reporting, codified at 49 CFR Part 579. Here is how it works.
Automotive
The dashboard light that warns of a low tire traces to a specific federal standard, FMVSS 138, which defines what a tire pressure monitoring system must detect and when it must warn. Here is the rule.
Automotive
Electric-powered vehicles meet a dedicated crash standard, FMVSS 305, that governs electrolyte spillage, energy-storage intrusion, and electric-shock protection. Here is what the regulation requires.
Automotive
Federal funding for EV charging comes with binding minimum standards — four ports, CCS connectors, and a 97% uptime floor. Here is what 23 CFR Part 680 actually mandates.
Automotive
The SAE J3016 levels are the taxonomy every regulator and carmaker uses to describe self-driving capability. Here is how NHTSA defines the line between driver assistance and an automated driving system.
Automotive
NHTSA's 2024 final rule created a new Federal Motor Vehicle Safety Standard requiring automatic emergency braking — including pedestrian AEB — on every light vehicle. Here is what the rule actually mandates.
Automotive
A motor-vehicle safety recall is not a press release — it is a defect report a manufacturer must file with NHTSA within five working days of determining a safety defect exists. Here is what the regulation requires.
Automotive
Federal Motor Vehicle Safety Standard No. 126 mandates electronic stability control on light vehicles and defines, in regulatory text, exactly what counts as an ESC system. Here is what the rule says.
Automotive
Honda's recall 26V332000 expands a prior campaign to cover a wide range of 2016-2026 Honda and Acura vehicles whose front passenger seat weight sensor may crack and short circuit. NHTSA's record states the air bags can then deploy unintentionally during a crash.
Automotive
Ford's recall 26V340000 covers 2021-2026 Bronco Sport and 2022-2026 Maverick vehicles whose front lower control arm ball joints may have been installed or repaired incorrectly. NHTSA's record carries a do-not-drive advisory until the inspection is completed.
Automotive
A newly published application describes cylindrical battery cells fitted with chain rings and pins so they snap together like links in a chain. The disclosure rethinks how individual cells are held into a pack.
Automotive
NHTSA campaign 26V054000 covers certain 2023–2024 Honda and Acura models whose driver's seat cushion frame may not have been tightened properly, leaving the seat loose and out of compliance with a federal seating standard.
Automotive
NHTSA campaign 25V893000 covers certain 2022–2024 Hyundai Tucson SUVs with an optional Mobis tow hitch wiring harness that can let water into the control module, risking trailer-light failure or a fire.
Automotive
NHTSA campaign 26V082000 covers certain 2024 Cadillac Lyriq EVs whose rearview camera screen can turn gray with no image — a failure of a federally required safety system.
Automotive
NHTSA campaign 25V595000 spans a long list of 2023–2025 Toyota and Lexus models whose instrument panel software can fail to display speed, brake, and tire-pressure warnings at startup.
Automotive
NHTSA campaign 26V371000 covers certain 2024 Ford Explorers with the 2.3L engine and 10R60 transmission, where an unintended PCM reset in motion can damage the park system and allow a rollaway.
Automotive
NHTSA campaign 26V255000 covers 2024–2026 Cybertrucks with 18-inch steel wheels whose brake rotor stud holes can crack and let a wheel stud separate from the hub.
Automotive
NHTSA campaign 24V204000 covers 2022-2024 Hyundai IONIQ 5 and related E-GMP EVs whose damaged ICCU can stop charging the 12-volt battery, cutting drive power.
