Nowadays, the big trend in everyone's schedule is big data, but in the field of machine-to-machine communication (M2M), small data is the most important. M2M communication can help automotive original equipment manufacturers (OEMs) better understand the performance and driving behavior of the car. Through in-depth exchange of information, M2M Communications allows OEMs to build and develop partnerships with their customers (distributors, suppliers and consumers) while providing innovative value-added services.

With embedded SIM cards and wirelessly transmitting data over a secure mobile network, M2M can collect all the important information from the car and use it for a wide variety of purposes. David Levine, global head of Vodafone's Automotive Business Development Division, explains the potential applications of M2M and the opportunities it will bring to automotive hardware and software engineers.
Industry driver
As a whole, the M2M industry is by far the largest in the automotive field, and its development has even overshadowed the use of M2M in the utilities, consumer goods and manufacturing sectors. Some analysts predict that the annual revenue of the automotive sector in 2020 will reach $19 billion. Its driving force is mainly from the EU regulations to support eCall. By 2015, all new cars will be required to provide M2M technology, so that in the event of a car accident, these cars can automatically notify the nearest emergency ambulance center.
Figure 1: eCall is one of the main drivers of the car M2M.
These cars require a 'small amount of data' to be sent to the emergency service center, including the exact location, time of occurrence and direction of the accident. With this technology, the area that supports this function can increase the response speed by 60%, thus saving more lives.
There are two ways to implement this mobile technology. The first is a bundled phone that "bundles" the consumer's phone to the car via a Bluetooth or USB connection and then uses the SIM card in the phone to connect to the eCall system. The second is an embedded SIM, which installs the SIM card inside the car and automatically connects to the eCall system when a collision is detected.
The European Commission strongly recommends the latter approach because the former bundling method works only when the driver remembers to connect the phone (usually via USB, WiFi or Bluetooth) and the battery is powered. The driver must also ensure that the phone is carried at all times. The embedded SIM approach eliminates this uncertainty and provides a more reliable and consistent response. Many in the industry predict that the European Commission will soon mandate the implementation of the embedded SIM approach.
M2M opportunities
In terms of road safety, eCall technology has the same potential impact as seat belts and airbags. However, there are upfront cost issues for OEMs who must install new mobile connectivity devices in their cars. Therefore, OEMs especially want to see new revenue opportunities for this new connection.
Cars can generate a lot of useful information, but the difficulty is to extract the information and convert it into meaningful content. The biggest opportunity for M2M is the ability to establish two-way communication between the car and the service provider, whereas in the past there was only one-way connection, for example, sending traffic information to the car via RDS-TMC.
Driver behavior
Tracking driver behavior is expected to be one of the biggest growth areas for M2M applications, provided the driver is willing to provide data for collection. One possible application is to provide a usage-based insurance model that can charge different fees depending on personal driving habits. The SIM card sends information to the insurance company about the speed of the car and the driver's driving behavior. Drivers who are safer to drive can benefit from paying lower premiums.
Information about how a car is being driven is also useful for car rental companies and fleet owners. The amount of charge can be determined based on, for example, the user's care of the car and whether or not the fuel is saved, because good behavior can extend the life of the car and reduce the depreciation loss.
The used car market can also benefit from it. It doesn't take long to verify whether the “rapper has a careful car owner†is true. The historical data on acceleration and speed can be used to quickly determine whether the owner is a racer. All these innovative technologies are It will positively affect the way people drive, and will help reduce vehicle speed, extend vehicle life, and develop more fuel-efficient driving behavior.
Relationship with consumers
Under normal circumstances, when a car leaves the showroom, the dealer will only see it again if the car needs service or repair. M2M helps to establish a closer connection between the driver and the dealer. Networked cars allow dealers to add a variety of services and interactions, and enhance their connections with consumers to help them differentiate their services from their competitors.
For example, car manufacturers can work with partners to provide infotainment services such as video, audio and applications directly to the car via a mobile network. Consumers are expected to get more services soon, such as car theft tracking, repair station services, and remote unlocking after placing the wrong key as part of the bundle sale.
The dealer can also use the diagnostic information from the car and remotely identify the engine problem, notify the driver when there is a fault, and remind them to come over for overhaul. This more advanced relationship is good for everyone in the value chain. Auto dealers and OEMs can use this to create new revenue streams, and consumers can benefit from well-designed add-on services.
Use in the public domain
The public sector is also looking forward to seeing how cars with M2M capabilities can help them improve the services they provide. When the road is full of connected cars, the data generated by these cars will be able to provide a wide range of anonymous traffic information, which will help them better understand their car network.
Real-time detailed traffic information based on vehicle speed and brake data helps drivers maintain a reasonable speed in line with current road conditions, and helps city management to take action when needed, and quickly avoids traffic jams and other routes to mitigate Congestion.

Using road-level information forwarded by cars can also provide better support in adverse weather conditions. ABS and vehicle stability information helps to find thin borneol on the road, which in turn enables more accurate and efficient dispatch of roller compactors, saving taxpayers' funds and ensuring maximum safety.
The unresolved data of vehicles collected from cars can also help the relevant functional departments to detect small defects on the road as early as possible and avoid the development of major faults. This means that these defects can be quickly disposed of before they are large enough to damage the car and endanger life. Road closures can be fewer and closure times can be shorter, minimizing traffic chaos and maintenance costs.
The future of M2M
M2M technology has made these services a reality. In the next few years, as OEMs introduce a new generation of cars, we will increasingly see M2M services becoming a key part of OEM products. OEMs will also use data collected from older models with M2M capabilities to enhance the performance of next-generation vehicles.
