Method for detecting movement for controlling an opening

A method for detecting movement for controlling an opening of a motor vehicle, notably for opening and closing a sliding door, said opening being configured to move between a closed position and a maximum open position, said vehicle comprising a control system for controlling the opening and closing of the opening, said control system comprising:

• a motor configured to move the opening between its closed position and its maximum open position, and vice versa;
• an electronic control unit configured to receive a control signal and to control said motor as a function of the received control signal;
• a detection sensor comprising a control module, a first detection element configured to perform measurements in a first detection zone and a second detection element configured to perform measurements in a second detection zone, distinct from the first detection zone, said control module being configured to detect a gesture of a user in the first detection zone based on measurements performed by the first detection element and to send a control signal to the electronic control unit when a gesture of the user has been detected;
• said method, implemented by the detection sensor, comprising:
• detecting a gesture of the user in the first detection zone and/or the second detection zone;
• confirming the gesture of the user;
• sending the electronic control unit a control signal for activating the motor;
• deactivating the second detection element;
• reactivating the second detection element if no gesture of the user is detected in the first detection zone until the opening reaches its closed position or its maximum open position;
• sending a control signal to the electronic control unit to stop the motor and reactivating the second detection element if a gesture is detected in the first detection zone;
• wherein the control module for controlling the detection sensor is configured to increment a timer and to store a target duration in a memory corresponding to the time required for the opening to transition from its closed position to its maximum open position, and vice versa, and wherein sending the signal to the electronic control unit is accompanied by the beginning of the incrementation of said timer, and the step of reactivating the second detection element if no gesture of the user is detected in the first detection zone until the opening reaches its closed position or its maximum open position is performed when the timer reaches the stored target duration.
