ABSTRACT:
The present invention relates to a method and a system for providing an optical signal at the rear of a vehicle to warn the following traffic of an ongoing electronic control intervention in the vehicle behavior. Such an electronic control function can be for instance ABS, TCS or automatic yaw control. A preferred embodiment of the invention utilizes the center brake light of a vehicle to emit an intermittent optical signal during electronic control. In case of ABS, the two side brake lights shine continuously to indicate a brake pedal actuation while the center brake light flashes in an on/off- mode according to the electronic antilock control.
