Method for filtering the commands of a control system for a vehicle, in particular for a motor vehicle, said control system comprising: - a first control module comprising a first touch screen, said first control module being configured to allow the control of a first plurality of functions of the vehicle - a second control module comprising a second touch screen, said second control module being configured to allow control of a second plurality of functions of the vehicle, and - a control box electronically connected to the first control module and the second control module, said control box being configured to allow control of the first plurality of functions and the second plurality of functions, said filtering method comprising the following steps - the sending by the first control module of a first message called "first status message" comprising a status of said first control module, said status being a status in the process of being activated corresponding to the start of a press, an active status corresponding to a press in progress, a status in the process of being deactivated corresponding to an end of a press or an inactive status corresponding to no press in progress - the reception, by the control box, of said first status message, - the detection, by the control box, of said deactivation state of the first control module, - after a first duration, the sending by the second control module of a second message, called "second status message" comprising a status of said second control module, said status being an active status, a status in the process of being activated, a status in the process of being deactivated or an inactive status - receiving, by the control box, said second status message - detection, by the control box, of said state being activated of the second control module, - after a second predetermined period of time, the sending by the second control module of a third message, known as a "third status message", comprising a status of the said second control module, the said status being an active status, a status in the process of being activated, an end of activation status or an inactive status - receiving, by the control box, said third status message - detection, by the control box, of said state in the process of deactivation of the second control module, - after the detection of the state being activated and, after said second duration, of the state being deactivated of the second control module, the detection of a request to activate a function on the second control module, and - authorising the activation of said function, by the control box, if and only if the first duration is greater than or equal to a predetermined threshold and if no state in the process of activation has been detected on the first control module during said second duration. - a first control module comprising a first touch screen, said first control module being configured to allow the control of a first plurality of functions of the vehicle - a second control module comprising a second touch screen, said second control module being configured to allow control of a second plurality of functions of the vehicle, and - a control box electronically connected to the first control module and the second control module, said control box being configured to allow control of the first plurality of functions and the second plurality of functions, - the sending by the first control module of a first message called "first status message" comprising a status of said first control module, said status being a status in the process of being activated corresponding to the start of a press, an active status corresponding to a press in progress, a status in the process of being deactivated corresponding to an end of a press or an inactive status corresponding to no press in progress - the reception, by the control box, of said first status message, - the detection, by the control box, of said deactivation state of the first control module, - after a first duration, the sending by the second control module of a second message, called "second status message" comprising a status of said second control module, said status being an active status, a status in the process of being activated, a status in the process of being deactivated or an inactive status - receiving, by the control box, said second status message - detection, by the control box, of said state being activated of the second control module, - after a second predetermined period of time, the sending by the second control module of a third message, known as a "third status message", comprising a status of the said second control module, the said status being an active status, a status in the process of being activated, an end of activation status or an inactive status - receiving, by the control box, said third status message - detection, by the control box, of said state in the process of deactivation of the second control module, - after the detection of the state being activated and, after said second duration, of the state being deactivated of the second control module, the detection of a request to activate a function on the second control module, and - authorising the activation of said function, by the control box, if and only if the first duration is greater than or equal to a predetermined threshold and if no state in the process of activation has been detected on the first control module during said second duration.
