Keyless Entry
The electronic car key authenticates the driver, allows him to access the vehicle and to start it.
Safety & Security
Vehicles are increasingly interconnected with the environment, other vehicles, but also with the traffic infrastructure and to the internet. For the driver, this has many advantages, but at the same time growing data streams mean a higher risk of manipulation. Therefore, the vehicle needs:
- Safety: It ensures, for instance, that brake systems function properly.
- Security: Data streams – for example in the on-board electronic system – need to be protected permanently from attacks.
Car2Cloud
Via the cloud the driver obtains real-time information about the traffic situation.
Car2Car
Information from nearby vehicles is used to create alerts for the driver.
Car2Cloud Traffic Warning
In case of an accident on the chosen route, the driver receives a traffic warning via the cloud. The navigation system identifies the blocked route section and recommends the best alternative route. The authenticity and integrity of this data must be ensured to avoid misuse and wrong navigation.
eCall – Saving time, saving lives
In case of an accident, vehicles equipped with an eCall (emergency call) system, automatically make an emergency call to the European Emergency Number 112. The vehicles get directly connected with the nearest emergency call center. The system transmits further information to the center, for example:
- exact time of the accident and
- position of the accident vehicle.
This information is passed on to the emergency vehicles which arrive faster at the scene of the accident. So the eCall system contributes to help the victims quickly and to save their lives.

Remote Update
Via the cloud, the car autonomously communicates with an authorized car repair shop.
Info Components
When communicating with the car repair shop, the car also transmits data on consumable materials and necessary spare parts.
Service Interval
If maintenance or repair of the vehicle is due, the system automatically makes an appointment with the car repair shop.
Tuning Protection
Also, the communication between the car and the car repair shop could improve the protection against unauthorized engine tuning or odometer manipulation: microcontrollers and the software stored therein are protected from unauthorized copying and manipulation.
Call / Distraction
The driver is shortly distracted by a phone call and comes too close to the vehicle ahead.
Safety System
The car’s onboard communication ensures that the safety system receives all needed information: It causes the vehicle to brake.
Radar + Brake
Radar sensors detect the critical distance and communicate with the vehicle’s brake system.
Distance OK
The car’s onboard communication works error-free: It restored the necessary safe distance to the vehicle ahead.
Hackers
The safety-critical communication between the systems must be protected from hacker attacks.
Onboard Communication
Sensors are an important element of assistance systems. In this case, the radar sensors of the vehicle distance assistant detect if a car gets too close to a vehicle ahead. Microcontrollers help the car react correctly in this situation:
- They evaluate the sensor information
- Activate the brakes at the right moment and with the required force
For these two functions, the data and their processing in the microcontrollers must be protected from tampering.
With the car’s increasing external communication, the risk of hacking attacks, which could endanger the safety of passengers and the vehicle, rises. The next step of assisted driving – autonomous driving – is only possible if the driver can fully rely on all systems being protected from unauthorized access.
Voice Control
By using voice control via a smartphone, the driver asks the car cloud to search for parking spot.
Search for a parking space
The car cloud identifies a free space for the driver in the nearest parking garage. The car is routed there.
eTicketing
The driver pays the parking fee with his smartphone. The parking garage clearly identifies him, grants access and performs the payment.
Safe eTicketing
When buying an electronic ticket (eTicketing) via mobile devices it is very important to protect personal data and pass codes – e.g. credit card information – from unauthorized access. All communication channels that transmit sensitive information need to be protected – for example with the help of encryption technologies: These ensure that third parties cannot access personal data or bank accounts.

Vehicle Positioning
GPS tracking allows the driver to determine his exact position (street address, postal code, city) and the current route at any time. Thus, he always knows exactly where the vehicle is at any given time – even in case of theft.
Immobilizer
By turning off the engine the electronic immobilizer is automatically activated. While it is active, unauthorized users cannot start the engine.
Data Protection
All data stored in the computer and in the control units of the vehicle must be safe and protected from unauthorized access at any time. Semiconductor technologies provide the necessary protection: Even when the driver has already left the car.
