Radar Systems - the sound of safety

Autoliv offers a wide range of industry leading radar sensors that provide a variety of Active Safety features.

Automotive radar devices are now appearing in passenger vehicles all over the world. These devices are used in advanced cruise control systems, which can direct a vehicle’s accelerator and braking systems, controlling the distance between it and another vehicle.
 
The radar sensors note vital information, such as range, angle and doppler velocity. This information is used to determine the driving situation and warn the driver in potentially dangerous events. If the driver does not take appropriate action in time and a crash is about to happen, advanced radar systems can take control of the vehicle to avoid the crash or lessen the accident’s severity. This high level of safety functionality is maintained in bad weather and no light, when driving conditions are at their worst.
 



Virtual Crash Zone
 
The radar transmitter emits signals that bounce back from objects ahead, at the side and to the rear of the vehicle, which are captured by the multiple receivers integrated throughout the vehicle. The radar system detects and tracks objects around the car, warning the driver of a potential collision or initiating electronic stability control intervention.
