1. A headlamp control system for a vehicle, said headlamp control system comprising:

  • an imaging sensor, said imaging sensor comprising a two-dimensional array of light sensing photosensor elements, said imaging sensor monitoring a scene forward of the direction of travel of the vehicle;

    a control, said control processing data from said imaging sensor and generating at least one control output;

    selection of a high beam state and a low beam state for a vehicle headlamp of the controlled vehicle being responsive to said control output, selection of the high beam state and the low beam state being determined responsive to a detection of an object of interest;

    said control responsive to a signal indicative of a vehicle speed of the controlled vehicle, said control inhibiting adjustment of the vehicle headlamp from a low beam state to a high beam state when the vehicle speed is below a threshold speed level; and

    said control responsive to data indicative of a vehicle trajectory of the controlled vehicle, said control inhibiting adjustment of the vehicle headlamp from a low beam state to a high beam state when a radius of curvature of the vehicle trajectory is below a threshold value.
