Extension of intelligent cruise control systems by velocity profile planning components

Interests have arisen concerning ICC (intelligent cruise control) systems, which support the driver by keeping a nominal velocity dependent gap between vehicles. Thus, the risk of accidents is reduced. However, as ICC does not consider upcoming bends, this behavior can result in dangerous situations for the automated car. To face this problem, ICC has to be extended by a strategy taking the road geometry in front of the vehicle into account. Thus, if the velocity in front of a bend is too high, a special module containing an additional velocity profile planning component will automatically take over. Then, the velocity is exclusively controlled depending on road parameters. In this case, ICC changes to standby. Particularly, in front of a bend, the speed will be reduced in time. After the bend, the car will accelerate again and ICC will take over
