Method and system for reducing a reaction delay time of a vehicle safety control device
Method for reducing a reaction delay time of a vehicle safety control device which makes interventions into the control of the vehicle as a result of a surrounding situation in which there is a risk of collision, wherein the vehicle safety control device makes a first intervention into the control of the vehicle before the surrounding situation in which there is a risk of collision is validated.
1. A method for reducing a reaction delay time of a vehicle safety control device which performs interventions in a vehicle control due to an environmental situation exhibiting a risk of collision, the vehicle safety control device capable of performing a first intervention and a second intervention in the vehicle control to reduce the risk of collision, the second intervention having a higher magnitude than the first intervention, the method comprising:
detecting, via the vehicle safety control device, an environmental situation exhibiting a risk of collision,
beginning a validation of the environmental situation and performing, via the vehicle safety control device, the first intervention in the vehicle control before completing the validation of the environmental situation exhibiting a risk of collision;
wherein the vehicle control comprises a braking device and a steering device, and the first intervention in the vehicle control is a slight braking intervention in the braking device or a slight steering intervention in the steering device which is not intended to be sufficient alone for preventing an impending collision.
2. The method as claimed in claim 1 further comprising, ending the first intervention in the vehicle control if the environmental situation exhibiting a risk of collision is not validated.
3. The method as claimed in claim 1 further comprising:
determining a period of time available for avoiding the collision; and
detecting that the period of time available for avoiding the collision is not sufficient for performing a validation of the environmental situation before initiating the second intervention and, in response thereto, performing the first intervention in the vehicle control.
4. The method as claimed in claim 3 further comprising performing the second intervention in the vehicle control when the environmental situation exhibiting a risk of collision has been validated via an environmental detection device or a vehicle-to-X communication device of the vehicle safety control device.
5. The method as claimed in claim 1 further comprising the vehicle safety control device outputting a warning to the driver in addition to performing the first intervention in the vehicle control.
6. The method as claimed in claim 1 wherein the steering intervention is an addition of torque to a steering torque or an increase of angle to a steering angle.
7. The method as claimed in claim 1 further comprising indicating to the driver whether a first intervention has been performed.
8. The method as claimed in claim 1 further comprising detecting the environmental situation on the basis of receiving a signal from a vehicle-to-X communication device or an environment detection device.
9. The method as claimed in claim 8 , further comprising detecting the environmental situation on the basis of receiving a signal from at least one of a radar, a camera, a lidar, and a laser.
10. The method as claimed in claim 8 , further comprising in that the vehicle-to-X communication device communicating on the basis of receiving a signal via at least one of the following types of connection:
a WLAN connection,
an ISM connection,
an infrared connection, and
a mobile radio connection.
11. The method as claimed in claim 8 further comprising performing the validation of the environmental situation exhibiting a risk of collision via the environment detection device first detecting the environmental situation exhibiting a risk of collision in that the environment detection device detects the environmental situation exhibiting a risk of collision over a period of time which is sufficiently long for validation.
12. The method as claimed in claim 1 further comprising performing validation of the environmental situation exhibiting a risk of collision via receiving a signal from an environment detection device or a vehicle-to-X communication device.
13. A system for reducing a reaction delay time of a vehicle safety control device comprising:
a vehicle control in the form of at least one of a braking intervention device and a steering intervention device,
an environment detection device,
a vehicle-to-X communication device,
a vehicle safety control device, the vehicle safety control device, the vehicle safety control device capable of performing a first intervention and a second intervention in the vehicle control to reduce the risk of collision, the second intervention having a higher magnitude than the first intervention, the vehicle safety device configured to detect an environmental situation exhibiting a risk of collision and to begin a validation of the environmental situation and to perform a first intervention in the vehicle control before validation of the environmental situation exhibiting a risk of collision is completed, wherein the first intervention is a slight braking intervention in the braking intervention device or a slight steering intervention in the steering intervention device which is not intended to be sufficient alone for preventing an impending collision.
