- the system When the motorized closure of an opening is controlled 1, the system is configured to perform one or more tests related to this closure to determine if the closing speed parameter is relevant. To do this, the system will, in a preliminary step 2, determine whether the closing operation is part of a measurement cycle or not. This condition will be seen in detail later. When this is the case, it will perform one or more tests to determine the veracity of at least one predefined condition. In the exemplary embodiment illustrated in the logic diagram of FIG. 1, only one condition is tested. When this is not the case the system returns to its initial state after posting the order. Indeed, as we will see later, the sash closure operations used in the same measurement cycle may not be successive.

- a speed condition a pressure condition on the vehicle structure
- a pressure condition in the passenger compartment a pressure condition in the passenger compartment
- a force condition at the actuator (s) a condition of stress at the end of closure actuator

It will therefore carry out prior to said speed increase command 16, a safety test 18 by comparing the calculated increased speed Vm with the maximum authorized speed Vmax for the opening and the system is configured to allow not order a speed increase that is greater than the maximum speed. If the result of the safety test shows that the calculated modified speed should be greater than the maximum speed, this would be replaced by the maximum speed. In other words, the system is configured to control an increase in the closing speed of the opening at a modified speed Vm which is equal to the maximum authorized speed Vmax. The relevance test is then completed 9, and the system will initiate a new measurement cycle and a new relevance test, the modified speed (in this case, Vmax) having become the new initial speed Vi.
- the system is further configured not to allow the predetermined minimum speed to be exceeded. It will therefore carry out prior to said speed reduction command, a safety test by comparing the calculated reduced speed Vm to the minimum authorized speed Vmin for the opening and the system is configured to allow not to control a decrease in speed which is less than the minimum speed. If the result of the safety test shows that the calculated modified speed was to be lower than the minimum speed, this would be replaced by the minimum speed. In other words, the system is configured to control a decrease in closing speed of the opening at a modified speed Vm which is equal to the minimum authorized speed Vmin. The relevance test is then completed, and the system will initiate a new measurement cycle and a new relevance test, the modified speed (in this case, Vmin) having become the new initial velocity Vi.

- the increment value dV (+) is different from the decrement value dV (-), more preferably the incrementation value dV (+) is less than the decrement value dV (-).
- dV (+) is chosen to be between 0.6 dV (-) and 0.9 dV (-).
- the invention is then remarkable in that the system is configured to repeat the measuring cycle, determining the rate of veracity of the condition tested and the test of relevance as often as necessary until the speed of the opening is considered to be correct and that the result of the relevance test no longer modifies the closing speed of the sash.
- the system will converge towards the ideal speed.
- the system will command to increase or decrease the speed according to a differential of a value dV which is variable and determined jointly or successively to the relevance test.
