Overview
Vehicle-to-Everything (V2X) technology enables cars to communicate with their surroundings and makes driving safer and more efficient for everyone. By making the invisible visible, V2X warns the driver of road hazards, helping reduce traffic injuries and fatalities. In addition to improving safety, V2X helps to optimize traffic flow, reduce traffic congestion and lessen the environmental impact of transportation.
V2X is a key component for full autonomous driving.
V2X need message package signing & verification which need high CPU loading if used CPU. Qualcomm recommend their customers to use NXP i.MX8X/XL which have HSM as their modem’s companion chip.
Two major components in the system: RSU (Road Side Unit) and OBU (On Board Unit). Both have similar system design, with minor differences.
