A driver assistance system and an operating method thereof are configured and adapted to perform autonomous longitudinal and/or lateral control of a vehicle. At least one control task for longitudinal and/or lateral control of the vehicle can be transferred from the driver to the driver assistance system. This involves informing the driver that a control task can be transferred to the system, and then transferring the control task from the driver to the system in response to the driver ceasing a manual control of this control task.

The invention relates to a method for operating a driver assistance system designed for autonomous longitudinal and/or lateral control of a vehicle, wherein at least one control task for longitudinal and/or lateral control of the vehicle can be transferred from vehicle operator to the driver assistance system. The invention further relates to a driver assistance system designed to implement the method of the invention.
Driver assistance systems for autonomous longitudinal and/or lateral control of a vehicle, i.e. designed to assume one or more longitudinal and/or lateral control tasks of the vehicle, are known from the art in different realizations. Such systems usually have in common that the vehicle operator can transfer one or more control tasks for longitudinal and/or lateral control to the corresponding driver assistance system if required.
The control tasks concerning longitudinal control of the vehicle include, for example, controlling the longitudinal acceleration and longitudinal speed of the vehicle or the vehicle speed in general and maintaining a specific distance from a preceding vehicle. These control tasks can be performed either manually by the vehicle operator, in particular through manual control or actuation of the brake (brake pedal) and the accelerator (accelerator pedal), or autonomously by a driver assistance system which is connected to the corresponding control devices in the vehicle.
According to a preferred realization of the method according to the invention the vehicle operator is informed whether or when he has to assume the at least one control task again, in particular if this has been preceded by a transfer of the at least one control task to the driver assistance system. According to the invention the assumption of the at least one control task by the vehicle operator, i.e. a transfer of the control task from the driver assistance system to the vehicle operator, occurs when the vehicle operator reassumes the corresponding manual control of the vehicle, i.e. in particular when he operates once again the operational element designed for manually performing the respective control task. The operational elements can thus also be, for example, the steering wheel and/or the pedals (brake, accelerator) of the vehicle.
According to a further preferred realization of the method according to the invention the vehicle operator is informed, by means of outputting at least one indication, whether the at least one control task can be transferred to the driver assistance system or whether the vehicle operator has to reassume the at least one control task. Outputting the indication can be done, for example, by means of visual display elements within the field of view of the vehicle operator, by means of acoustic signals and/or by means of haptically perceivable signaling devices. The at least one indication is preferably the output of at least one of the following information: Control task can be transferred to the driver assistance system. Control task cannot be transferred to the driver assistance system. Control task has to be (re)assumed by the vehicle operator.
According to the invention, separate indications or separate output devices can be provided for all control tasks which can be transferred to the driver assistance system, in particular such that the diver recognizes which of the control tasks can and cannot be transferred at the moment and which of the control tasks have to be reassumed by him.
