Abstract
A driver assistance system for a motor vehicle for automated driving with automated longitudinal guidance, wherein when automated longitudinal guidance is active in an automatic mode, automated longitudinal guidance is brought about taking into account a predefinable setpoint speed. The system includes a first detection unit, configured to detect a defined stationary state situation which is set on the basis of a preceding automated braking process of the motor vehicle to the stationary state, a second detection unit, configured to detect accelerator pedal activation, and an evaluation and control unit, configured to actuate a manual mode when actuator pedal activation is detected during a defined stationary state situation.
Claims12
A driver assistance system for a motor vehicle for automated driving with automated longitudinal guidance, wherein when automated longitudinal guidance is active in an automatic mode, automated longitudinal guidance is brought about taking into account a predefined setpoint speed, comprising:
- at least one processing device configured to:
- detect a defined stationary state situation which occurs owing to a preceding automated braking process of the motor vehicle into the stationary state;
- detect accelerator pedal actuation;
- temporarily activate a manual mode of the automated longitudinal guidance in response to accelerator pedal actuation detection during the detected defined stationary state situation, wherein, in the manual mode of the automated longitudinal guidance, a driving speed correspond to a speed that is predefined by the accelerator pedal actuation instead of the predefined setpoint speed;
- determine that at least one predefined abort criterion is satisfied by determining that the driving speed has reached and exceeded a predefined speed limiting value while in the manual mode;
- and
- automatically abort the manual mode of the automated longitudinal guidance and automatically resume the automatic mode of the automated longitudinal guidance in response to determining that the at least one predefined abort criterion is satisfied.
A method for automated driving with automated longitudinal guidance, wherein when automated longitudinal guidance is active in an automatic mode, automated longitudinal guidance is brought about taking into account a predefined setpoint speed, the method comprising:
- detecting a defined stationary state situation which occurs owing to a preceding automated braking process of the motor vehicle into the stationary state;
- detecting accelerator pedal actuation;
- temporarily activating a manual mode of the automated longitudinal guidance in response to detecting the accelerator pedal actuation during the detected defined stationary state situation, wherein, in the manual mode of the automated longitudinal guidance, a driving speed correspond to a speed that is predefined by the accelerator pedal actuation instead of the predefined setpoint speed;
- determining that at least one predefined abort criterion is satisfied by determining that the driving speed has reached and exceeded a predefined speed limiting value while in the manual mode;
- and
- automatically aborting the manual mode of the automated longitudinal guidance and automatically resuming the automatic mode of the automated longitudinal guidance in response to determining that the at least one predefined abort criterion is satisfied.
A computer product comprising a non-transitory computer readable medium having stored thereon program code which, when executed by one or more processors, carries out a method comprising:
- operating a motor vehicle with automated longitudinal guidance active in an automatic mode of the automated longitudinal guidance, wherein, when in the automatic mode, automated longitudinal guidance is brought about taking into account a predefined setpoint speed;
- detecting a defined stationary state situation which occurs owing to a preceding automated braking process of the motor vehicle into the stationary state;
- detecting accelerator pedal actuation;
- temporarily activating a manual mode of the automated longitudinal guidance in response to detecting the accelerator pedal actuation during the detected defined stationary state situation, wherein, in the manual mode of the automated longitudinal guidance, a driving speed correspond to a speed that is predefined by the accelerator pedal actuation instead of the predefined setpoint speed;
- determining that at least one predefined abort criterion is satisfied by determining that the driving speed has reached and exceeded a predefined speed limiting value while in the manual mode;
- and
- automatically aborting the manual mode of the automated longitudinal guidance and automatically resuming the automatic mode of the automated longitudinal guidance in response to determining that the at least one predefined abort criterion is satisfied.
