Abstract:
A method and a device for determining a warning condition on the basis of brake light detection. Image data are received from a front camera of a vehicle. It is determined whether a brake light of a preceding vehicle is active. An initiation threshold is lowered or a confidence value is raised if the brake light is active. An estimated risk value is derived from the image data of the front camera and a warning signal is produced, if the estimated risk value exceeds the initiation threshold.

Claim (Index 9):
A controller for the activation of automotive safety features, the automotive safety features comprising at least one active safety feature, the controller comprising:\n an input connection for receiving image data of a front camera of a present vehicle; an output connection for outputting a warning signal, wherein the controller is configured to:\n receive image data from the front camera, the image data comprising image frames; \n determine a detection area in the image frames of the front camera, the detection area comprising a position of a left brake light and of a right brake light of a preceding vehicle; \n estimate respective positions of the left brake light and of the right brake light within the detection area; \n determine whether at least one of the left brake light and the right brake light is active by evaluating an intensity distribution in the detection area; \n lower an initiation threshold if it is established that at least one of the left brake light and the right brake light of the preceding vehicle is active; \n derive an estimated risk value from the image data of the front camera, wherein the estimated risk value is derived from at least one of a distance from the preceding vehicle, a relative speed of the preceding vehicle, and a deceleration of the preceding vehicle, and \n produce a warning signal, if the estimated risk value exceeds the initiation threshold, and to output the warning signal via the output connection.
