Method For Operating a Vehicle Having A Collision Avoidance System And Device For Carrying Out Such A Method
A method for operating a vehicle having a collision avoidance system including a sensor for sensing potential other parties to a collision and having an evaluator, connected to a control unit, for evaluating a risk of a collision. It is proposed that when the other party to a collision comes relatively close in the lateral direction, an actuator system is activated in order to predefine a setpoint trajectory of the vehicle in order to avoid a lateral collision. In addition, a device for operating the method is provided.
