Abstract: The invention relates to a method and a device for regulating the speed of an autonomous vehicle, referred to as ego vehicle, comprising an adaptive cruise control, said method comprising the steps of activating (201) said adaptive cruise control, receiving (202) information relating to said target vehicle, referred to as target information, receiving (203) information relating to said ego vehicle, referred to as ego vehicle information, determining (204) an inter-vehicle time, determining (205) an alert signal from said target information and said ego vehicle information, determining conditions (206) for substituting (207) a target acceleration for a setpoint acceleration of said cruise control.

Abstract: The invention relates to an autonomous driving method for a motorized land vehicle, called an ego-vehicle 102, by adaptive speed regulation based on a target speed. The method is suitable for detecting a first target vehicle 104 and for calculating a relevance indicator for the first target vehicle 104, which is configured to characterize a probability of presence of the first target vehicle. Upon detection of a loss of detection of the first target vehicle 104 and if the relevance indicator is greater than a predetermined deselection value, the method calculates an autonomous driving setpoint using the information on the movement of the first vehicle target 104, the target speed and the speed of the ego-vehicle 102.
