A collision avoidance control system for a vehicle is provided which is designed to determine a target collision avoidance deceleration required for a system vehicle equipped with this system to bring a relative speed between the system vehicle and a target object into agreement with substantially zero without a physical collision with the target object and to determine a possibility of collision with the target object as a function of the target collision avoidance deceleration. When the possibility of collision is higher than a given threshold level, the system starts to decelerate the system vehicle. This enables the avoidance of collision with the target object at a decreased operation load on the system.

Architecture for enhancing the encoding/decoding of information of a channel. A stream of incoming information bits are arranged into a first array of information bits. The first array of information bits are processed into a first code of bits, which bits form a plurality of first code words having a minimum distance to neighboring error events. Selected bits of the first code are rearranged into a second array of bits by intermittent successive rotations of the selected bits of the first code. A second code is then generated from the second array of bits to increase the minimum distance to the neighboring error events.
