Abstract:
1. A method for setting a parameter of an image-based driving assistance system on a vehicle, the driver assistance system including a lane-keeping assistance system, the method comprising: creating a state recognition profile including a plurality of respective previous instantaneous gains and previous instantaneous exposure times associated with one of an instantaneous daytime state and an instantaneous night-time state; recording a current frame; reading at least one of a current instantaneous gain and a current instantaneous exposure time associated with the frame; identifying, based on the state recognition profile, if the at least one of the current instantaneous gain and the current instantaneous exposure time correspond to one of the instantaneous daytime state, the instantaneous night-time state, and a neither daytime nor night-time state; if the at least one of the current instantaneous gain and the current instantaneous exposure time correspond to one of the instantaneous daytime state and the instantaneous night-time state, adding the current instantaneous gain and the current instantaneous exposure time to the state recognition profile as an additional one of the previous instantaneous gains and previous instantaneous exposure times representing the one of the instantaneous daytime state and the instantaneous night-time state of the current instantaneous gain and the current instantaneous exposure time; if the at least one of the current instantaneous gain and the current instantaneous exposure time correspond to one of the instantaneous daytime state and the instantaneous night-time state, setting a parameter of the driver assistance system based on the corresponding state of the current instantaneous gain and the current instantaneous exposure time; and if the at least one of the current instantaneous gain and the current instantaneous exposure time do not correspond to one of the instantaneous daytime state and the instantaneous night-time state, maintaining a current state of the parameter of the driver assistance system.
