The U.S. Department of Transportation’s (USDOT) National Highway Traffic Safety Administration (NHTSA) recently issued a Notice of Proposed Rulemaking (NPRM) to mandate vehicle-to-vehicle (V2V) communication technology for new light vehicles in the United States. The road map that the NPRM set is clear – 100% of all new cars will have Dedicated Short Range Communication (DSRC) technology installed by 2023, increasing from 75% in 2022 and 50% in 2021.
NTHSA stated that V2V could eliminate or reduce the severity of up to 80 percent of non-impaired-driving crashes.
Using DSRC based technology, vehicles exchange information between one another in a radius of up to1 mile. These data communications occur in a 75 MHz band of the 5.9 GHz spectrum, which has been allocated by the US Government for use by vehicle safety and mobility applications. Secure messages are exchanged up to 10 times per second between the vehicles which contains information such as location, heading, speed, acceleration and braking. The information is processed to determine collision threats and a warning is issued to get drivers to take appropriate action in order to avoid an imminent crash.
Autotalks 2nd generation chipset is mass-market ready and exceeds all the requirements set by the NPRM.
|Readiness||100% market penetration in 2023||Yes.|
OEM should initiate SOPs from 2020 to achieve the desired ramp. Autotalks samples are available now for productization
|Communication||300m range at high speed (85-120mph)||Yes.|
Autotalks has the best receive sensitivity in market (-96dBm) and provides excellent performance at high mobility
|Latency||Age of BSM < 150mS||Yes.|
Autotalks eHSM having the fastest signing latency is capable of satisfying this requirement while facing standard GNSS delays
|Power-up||Vehicle shall begin transmission after 2 sec||Yes.|
Accelerated boot while maintaining highest level of security
|Security||State-of-the-art secure platform||Yes.|
Autotalks truly-secure solution offers unmatched security:
- Hardened security environment with strict enforcement of data flows.
- Smallest surface of attack, as every packet is verified, hence untrusted data is blocked at the lowest layer.
- Certified secure storage for protecting the sensitive data.
- Isolation of V2X from the in-vehicle network.
- Cryptoagility supporting security for decades to come.
