Method and control device for signaling a braking process on a trailer vehicle

摘要

In a method for signaling a braking process on a trailer vehicle coupled to a towing vehicle, at least one light on the trailer is actuated with an emergency brake signal during emergency braking and with a normal signal during a different driving state. The emergency brake signal causes a different actuation of the light than does the normal signal. The light can be actuated by a control signal of the towing vehicle, and the actuation state of the light can be influenced by at least one control device on the trailer. The control device detects the control signal generated by the towing vehicle and fed to the trailer to actuate the light, and analyzes the control signal. If it detects that the control signal is an emergency brake signal, it does not carry out a dedicated actuation of the light, or it effects a different actuation of the light than in other cases.

1. A method for signaling a braking process on a trailer vehicle coupled to a towing vehicle, at least one light disposed on the trailer vehicle being operable for emergency braking with an emergency braking signal and operable for a different driving state with a normal signal, the emergency braking signal causing different operation of the at least one light than the normal signal, and the at least one light being controllable by a control signal of the towing vehicle and by at least one control device disposed on the trailer vehicle, the at least one control device comprising at least one data processor, the method comprising using the at least one data processor to detect and analyze a control signal comprising a pulsed control signal for operating the at least one light that is generated by the towing vehicle and supplied to the trailer vehicle; identify the pulsed control signal as being an emergency braking signal; and, based on the identified pulsed control signal, avoiding generation of an anti-phase pulsed control signal for the at least one light that would cancel the pulsed control signal from the towing vehicle.
