Connected Cars with V2X

Engineering Solutions for Connected Car Services

Promwad offers engineering services for connected cars: we develop software and design hardware to empower our customers with their products for smart cities. With advanced cameras, sensors, and applications, vehicles can be connected to everything you need with vehicle-to-everything (V2X) communications standards.

When working on connected car designs, we implement our expertise in automotive, telecom, video & audio processing, as well as our experience in embedded and cloud software development. Our cross-functional team creates solutions that enable communication between vehicles (V2V), pedestrians (V2P), infrastructure (V2I), and homes (V2H).

Our Vehicle Connectivity Expertise

Vehicle сonnectivity includes integrating advanced features to enhance your system’s overall efficiency. Using vehicle-to-everything (V2X) technology, our engineers improve urban transportation infrastructure and ensure the comfort and safety of pedestrians and drivers. We use various wired and wireless communication technologies to establish connections between vehicles, cameras, and other sensors to facilitate the following functions:

  • Traffic management and transportation flow optimisation.
  • Prevention of collision with other road users or obstacles.
  • Predictive maintenance of cars.
  • IT security audit and protection against car hacking and theft.
  • Efficient use of city infrastructure (parking lots, standing areas, charging stations).

Automotive Connectivity Solutions

We offer automotive connectivity solutions that integrate your vehicles into the smart city ecosystem. With our expertise in V2X technologies and managed network solutions, our team enhances your systems by connecting them with other vehicles, pedestrians, and infrastructure.

Vehicle-to-Vehicle (V2V)

V2V technology forms networks between vehicles, allowing them to exchange information about their location, speed, and direction of movement. This real-time connection increases safety by alerting other drivers to potential collisions, obstacles, breakdowns, and other hazards.

We offer connected car services that involve the design of onboard automotive communication units. Powered with  V2V technology, the units can alert other drivers about external issues with their cars, such as damaged headlights or flat tyres.

The key aspect of the V2V solution is the integration of the in-vehicle infotainment (IVI) system module with the car's camera, which enables the module to recognise registration plates. If both cars' registration plates are in the database, the notifying car can alert another car of external damage through an encoded message sent through the stereo.



Vehicle-to-Infrastructure (V2I)

Vehicle-to-infrastructure (V2I) enables the transmission of information between vehicles and nearby infrastructure, such as traffic lights, road signs, and parking spaces. V2I technology provides real-time information related to road conditions, road closures, and other data from the car's surroundings. This information is essential for optimising routes, alleviating traffic congestion, and ensuring the safety of all road users.


Vehicle-to-Pedestrian (V2P)

Vehicle-to-Pedestrian (V2P) technology in automotive connectivity aims to enhance the safety of pedestrians and other vulnerable road users.

Our R&D projects involve cameras, sensors, radar, and LiDAR systems that can detect pedestrians and cyclists on the road and alert the driver of potential collisions. In dangerous situations, LiDAR systems can even trigger automatic braking.

This future automotive trend is expected to extend to wearable devices for pedestrians, so they can also receive alerts of potential collisions.


Vehicle-to-Network (V2N)

Vehicle-to-Network (V2N) refers to communication between vehicles and management networks, transport infrastructure, other vehicles, and pedestrians. We have extensive experience developing solution updates and positioning technology that enables our clients to accurately determine a car's location and its operational status.


Vehicle-to-Home (V2H)

Vehicle-to-Home (V2H) technology enables two-way electrical energy flow, allowing electric vehicles to provide power to residential homes and office buildings during power outages or serve as a power source for the electrical grid during peak demand periods.


Cellular V2X (C-V2X)

Cellular V2X scheme

Cellular Vehicle-to-Everything (C-V2X technology) utilises cellular networks to transmit real-time information between vehicles and other entities such as vehicles, pedestrians, infrastructure, and communication networks.

What are the future trends in the automotive industry related to connectivity and smart cars?


Some future trends in the automotive industry related to connectivity and smart cars include:

  • an increased use of AI and machine learning,
  • the expansion of V2X communication,
  • the development of autonomous and semi-autonomous driving technology,
  • the growth of the electric vehicle market,
  • a focus on software-defined vehicles,
  • the customisation and personalisation of the in-vehicle user experience.

Can you explain the difference between CV2X technology and other types of vehicle communication technologies?


Cellular Vehicle-to-Everything technology is a cellular-based communication protocol that allows vehicles to communicate with infrastructure, pedestrians and other vehicles. It differs from other types of automotive communication technologies, such as DSRC and LTE-CAT M1, which are short-range wireless communication protocols.


How does connected car engineering differ from traditional automotive engineering?


Connected car engineering requires extensive expertise in wireless communication protocols, cloud computing, cybersecurity, and data analytics. To enable seamless connectivity between the vehicle and its external environment, engineers must ensure data security between the car and the cloud while considering power consumption, heat dissipation, size limitations, and other factors.

How will emerging technologies such as 5G and edge computing impact connectivity in the automotive industry?


Emerging technologies such as 5G and edge computing are expected to significantly improve automotive connectivity by empowering fast and dependable communication between vehicles and other devices. The high bandwidth and low latency of 5G networks will allow real-time data transfer. Meanwhile, edge computing will enable data processing closer to the source, thereby improving responsiveness and reducing latency.

What are the potential privacy concerns with connected cars engineering and how are they addressed?


One of the main privacy concerns related to connected car engineering solutions is the potential for unauthorised access to personal data, such as location information and driving behaviour. Manufacturers are implementing security measures such as encryption, firewalls, and intrusion detection features to address these concerns. Additionally, regulations, such as the EU's General Data Protection Regulation (GDPR) and California's Consumer Privacy Act (CCPA) provide guidelines for handling personal data in connected cars.
