Talking Cars are Coming Next!!

Driving is crazy, driving is fun, and driving is a sport. It’s all about having fun in one “machine.” Manufacturers are making vehicles talk to each other to minimize or avoid accidents.

In modern society, vehicles are an integral part of many people’s lives. They are incorporated with more and more high-tech devices. A common platform for vehicle communication is needed to create a system that supports safe driving, dynamic routing, emergency message distribution, and traffic conditions monitoring.

In 1984, “The Terminator,” a movie about a future in which machines were rising against humans, was released. We now know better, having arrived in this future. The devices will not kill us. They are taking us out of the equation.

Researchers claim that autonomous cars can reduce traffic by communicating to make highways more efficient. They will emit less harmful pollutants because they spend less time in traffic. They will also give those who cannot drive due to age or disability greater mobility.

NHTSA and eight automakers conducted a one-year research project to see if vehicles communicating with each other could prevent accidents. The Safety Pilot Model Deployment Project brings together approximately 1500 cars equipped with Dedicated Short-Range Communications (DSRC) devices that constantly transmit “here I am” signals to other vehicles around them.

Sensors in the vehicle can be used for vehicle-to-vehicle communications to send messages from multiple services. These services include information about traffic jams, warnings of approaching rescue vehicles, or accident warnings. Information on weather or road conditions can also be exchanged.

The warning system can alert drivers of hazards, such as parked cars or vehicles moving in from the side. It can also detect and warn other vehicles if they are too close together.

The cars are equipped with radios which broadcast safety messages ten times per second about the speed and location of other vehicles in their vicinity. Messages are sent on a Wi-Fi frequency designated for the vehicle to vehicle (V2V). The DSRC signal can be picked up from all angles by a car, unlike a unidirectional radar or sensor. The “here I am” message is not blocked by other vehicles; for example, it can detect a hazard that’s two cars in front.

Providing that extra buffer for a driver who may be distracted by another passenger or fiddling around with the radio is essential. This will allow him to focus on the road again and respond appropriately.

To get a comprehensive safety benefit, many vehicles need DSRC. This penetration will likely require a government mandate.

The trend to integrate new services into vehicles is increasing rapidly. The latest research field of communication networks is car-to-car communications. It’s both exciting and challenging. Car 2 Car communications is an investment for the future. With the ever-changing technology and new software, we will soon have cars that talk like robots.
