Method for controlling an openable panel of a motor vehicle by detecting a movement of a target

A method for controlling an opening of a motor vehicle by detecting a movement of a target, such as a hand or a foot of a user, said opening being able to be moved by an actuator so as to be able to control its opening speed, and/or its degree of opening between a fully open position, a fully closed position and at least one partially open intermediate position, said method comprising:

• (a) transmitting, using at least one transmitter, a radiofrequency signal, called transmitted signal, intended to at least partially reflect on said target;
• (b) receiving, using at least one receiver, a radiofrequency signal, called return signal, originating from the reflection of the transmitted signal on said target;
• (c) determining, based on the transmitted signal and the return signal, at least one characteristic from among a movement speed, a linear amplitude of movement, and/or an angular amplitude of movement, relating to a movement of the target relative to a determined zone of the vehicle;
• (d) controlling the degree of opening and/or the opening speed of the opening, using the actuator, and as a function of said characteristic relating to the movement of the target;
• the method implementing a comparison between:
• said at least one characteristic from among a movement speed, a linear amplitude of movement and/or an angular amplitude of movement, on the one hand;
• and
• calibration data for connecting said characteristic with an opening speed, respectively a degree of opening;
• such that:
• a high value of the linear amplitude of movement and/or of the angular amplitude of movement allows significant movement of the opening, and vice versa;
• and
• a fast movement speed allows fast movement of the opening, and vice versa.
