Abstract

An emergency braking system for a vehicle includes an emergency braking control unit configured to control the emergency braking system according to a first parameter set. The first parameter set is selected by the emergency braking control unit from a plurality of parameter sets. Each respective parameter set of the plurality of parameter sets is associated with a respective vehicle variant and adapts the emergency braking system to the respective vehicle variant. Each respective vehicle variant is characterized by a design of a braking system of the respective vehicle variant for adapting the emergency braking system of the respective vehicle variant to the design of the braking system of the vehicle variant. The first parameter set is associated with a first vehicle variant that characterizes the vehicle.

Claims (31)

1. An emergency braking system for a vehicle, the emergency braking system comprising:

a memory storing a plurality of parameter sets, each respective parameter set of the plurality of parameter sets corresponding to a different respective vehicle model series variant of a vehicle model series produced by a vehicle manufacturer, and

an emergency braking controller configured to:

select, based on a first vehicle model series variant of which the vehicle is an instance, a first parameter set from the plurality of parameter sets stored by the memory, the first parameter set corresponding to the first vehicle model series variant, and

generate, using the first parameter set as input, an emergency braking output signal for causing an emergency braking by service brakes of the vehicle.

2. The emergency braking system as claimed in claim 1 , wherein the memory is integrated within the emergency braking controller.

3. The emergency braking system as claimed in claim 1 , wherein each respective parameter set of the plurality of parameter sets comprises an identifier that characterizes the respective vehicle model series to which the respective parameter set corresponds.

4. A vehicle with an emergency braking system as claimed in claim 1 .

5. The emergency braking system as claimed in claim 1 , wherein each respective vehicle model series variant is defined by a respective service braking system.

6. The emergency braking system as claimed in claim 5 , wherein each respective service braking system is characterized by a respective efficiency of the respective service braking system, wherein each respective efficiency is determined by a braking force.

7. The emergency braking system as claimed in claim 5 , wherein a design of each respective service braking system is characterized by a design of a respective corresponding vehicle or type of vehicle.

8. The emergency braking system as claimed in claim 5 , wherein the respective service braking system is provided, by the manufacturer of the vehicle model series, for the respective vehicle model series variant.

9. The emergency braking system as claimed in claim 5 , wherein each respective parameter set includes parameters tailored to the respective service braking system that defines the respective vehicle model series variant.

10. The emergency braking system as claimed in claim 9 , wherein the parameters of each respective parameter set are specified by the manufacturer of the vehicle model series.

11. The emergency braking system as claimed in 1 , wherein the plurality of parameter sets corresponding to respective vehicle model series variants of the vehicle model series produced by the vehicle manufacturer includes parameter sets corresponding to respective vehicle model series variants different than the first vehicle model series variant.

12. The emergency braking system as claimed in claim 1 , wherein the parameters of the first parameter set are specified by the manufacturer of the vehicle model series, and

wherein the emergency braking controller is configured to generate, using the first parameter set as input, the emergency braking output signal by:

receiving, from one or more sensors, sensor signals,

calculating, using the first parameter set and the sensor signals as input, a collision probability, and

generating, based on the calculated collision probability the emergency braking output signal.

13. A method for controlling an emergency braking system in a vehicle, the method comprising:

selecting, from a plurality of parameter sets stored by a memory, a first parameter set, each respective parameter set of the plurality of parameter sets is corresponding with a respective vehicle model series variant of a vehicle model series produced by a vehicle manufacturer, the first parameter set corresponding with a first vehicle model series variant which the vehicle is an instance;

determining, using the first parameter set as input, a collision probability; and

outputting warning signals and emergency braking signals depending on the determined collision probability.

14. The method as claimed in claim 13 , wherein the first parameter set is selected according to a unique identifier characterizing the first vehicle model series variant.

15. The method as claimed in claim 13 , wherein a time to a collision is determined depending on the selected first parameter set and depending on the time an emergency braking point in time is determined at which the emergency braking signal is output to initiate autonomous emergency braking.

16. The method as claimed in claim 15 , wherein a first point in time for outputting a warning to the driver depending on a warning signal is determined according to the emergency braking point in time and while taking into account the selected first parameter set.

17. The method as claimed in claim 16 , wherein an audible warning and a visible warning or a haptic warning is output to the driver.

18. The method as claimed in claim 15 , wherein a second point in time for outputting a warning to the driver depending on a warning signal is determined according to the emergency braking point in time and while taking into account the selected first parameter set.

19. The method as claimed in claim 7 , wherein a setpoint vehicle deceleration for carrying out the autonomous emergency braking is determined that results in a vehicle actual deceleration according to the selected first parameter set.

20. The method as claimed in claim 15 , wherein the points in time, the emergency braking point in time and the vehicle actual deceleration take statutory requirements into account.
