1. A method for assisting a driver of a motor vehicle in a driving maneuver, comprising:
- recording, by at least one sensor, surroundings of the vehicle;
identifying, by a hardware control unit and based on the recorded surroundings, an object located in the surroundings of the vehicle;
ascertaining, by the control unit, whether the vehicle is approaching the object;
calculating, by the control unit, a distance based on a first path estimated to be covered during a driver reaction time and a second path in which the vehicle can be manually braked after the reaction time;
outputting a warning to the driver when the vehicle approaches the distance from the object, the warning including a warning jerk; and
after the warning jerk has taken place, automatically reducing the speed of the vehicle;
wherein the warning jerk includes one of;
(i) a deceleration of the vehicle in which the speed of the vehicle is reduced, and subsequent positive acceleration of the vehicle in which the speed of the vehicle is increased; and
(ii) positive acceleration of the vehicle in which the speed of the vehicle is increased and subsequent deceleration of the vehicle in which the speed of the vehicle is reduced.

Abstract
In a method for assisting a driver of a motor vehicle in a driving maneuver, the surroundings of the vehicle are recorded, and it is checked whether at least one object is located in the surroundings of the vehicle, and it is ascertained subsequently whether the vehicle is approaching the object, and a warning to the driver is output if the vehicle approaches the object up to a critical distance. The driver is warned by a warning jerk, and after the warning jerk has taken place, the speed of the vehicle is automatically reduced.

11. A device, comprising:
-
sensors adapted to record surroundings of a vehicle; and a control unit adapted to; evaluate data for detecting an object recorded by the sensors; evaluate whether the vehicle is approaching the object; calculate a distance based on a first path estimated to be covered during a driver reaction time and a second path in which the vehicle can be manually braked after the reaction time; and based on the calculation; actuate brakes of the vehicle to generate a warning jerk when the vehicle approaches the distance from the object; and reduce the speed of the vehicle; wherein the warning jerk includes one of; (i) a deceleration of the vehicle in which the speed of the vehicle is reduced, and subsequent positive acceleration of the vehicle in which the speed of the vehicle is increased; and (ii) positive acceleration of the vehicle in which the speed of the vehicle is increased and subsequent deceleration of the vehicle in which the speed of the vehicle is reduced. - View Dependent Claims (16, 17, 18)
