1. An active safety system for a vehicle comprising:
- an external object sensor system arranged on a host vehicle, said sensor system being arranged to, within a detecting range of said sensor system, sense objects (k) external to said host vehicle and generate input data relating to said objects (k), wherein said input data includes an object position ((R, ψ
rel)(t)),a threat indicator which is arranged to assign a threat level (Tk(t)) to each external object (k) detected by the sensor system;
characterised in that said active safety system further includes;
an eye gaze recorder arranged for, recording the direction of gaze (φ
(t)) of a user, determined by an eye gaze monitor;
an awareness detector which is arranged to determine awareness (Ak(t)) of an object (k) based on an assessed observation, which observation is being assessed by use of a recorded direction of gaze (φ
(t)) of the user and said object position ((R, ψ
rel)(t)); and
a controller which is arranged to, for objects (k) detected by said sensor system and objects which the user is aware of ((Ak(t))=1), collect threat level data (Tk(t)) from said threat indicator, to store threat level data (Tk(t)) collected at different points in time, to assign a threat level awareness (Tk(tk0)) by selecting the threat level (Tk(t)) at which the object (k) was observed (tk0), and to compare the current threat level (Tk(t)) of the object (k) with the threat level awareness (Tk(tk0)).

Abstract
An active safety system for a vehicle includes an external object sensor system arranged on a host vehicle. The sensor system designed to sense objects external to the host vehicle and generate input data relating to the objects, wherein the input data includes an object position ((R, ψrel)(t)). Additionally, a threat indicator is included to assign a threat level (Tk(t)) to each external object (k) detected by the sensor system.

8. A method operated in an active safety system for a vehicle comprising the following process steps:
-
within a detecting range of a sensor system arranged on a host vehicle, sensing objects (k) and generating input data relating to objects external to said host vehicle, wherein said input data include an object position ((R, ψ
rel)(t)),recording the direction of gaze (φ
(t)) of a user, determined by an eye gaze monitor,determining awareness (Ak(t)) of an object (k) based on an assessed observation, which observation is being assessed by use of a recorded direction of gaze (φ
(t)) of the user and said object position;assigning a threat level (Tk(t)) to each external object (k) detected by the sensor system;
characterised in that the following further process steps are performed;for objects detected by said sensor system and objects which the user is aware of, collecting threat level data (Tk(t)) from said threat indicator, storing threat level data (Tk(t)) collected at different points in time, assigning a threat level awareness (Tk(tk0)) by selecting the threat level (Tk(t)) at which the object was observed (tk0), and comparing the current threat level (Tk(t)) of the object (k) with the threat level awareness (Tk(tk0)). - View Dependent Claims (9, 10, 11, 12, 13, 14)
