Abstract

L'invention concerne un procédé d'activation et de suspension d'une inhibition d'une réduction de traînée de boîte de vitesses automatique lors d'un pilotage automatique d'un véhicule délivrant des demandes d'arrêt et de redécollage du véhicule, des consignes de couple moteur, de freinage et de passage de vitesse (ADAS M, ADAS F). Une supervision est établie avec identification d'une phase d'arrêt par association d'une demande d'arrêt, d'une consigne de couple nul et de freinage en vigueur. En phase d'arrêt, il est effectué une inhibition de réduction (ADAS red tr) de traînée se traduisant par une consigne de couplage au neutre de la boîte, puis, en phase de redécollage, suite à une demande de redécollage et à une consigne de couple non nul, il est émis une suspension de l'inhibition (ADAS red tr) se traduisant par une consigne de couplage correspondant au passage d'un premier rapport de boîte de vitesses.The invention relates to a method for activating and suspending an inhibition of an automatic gearbox drag reduction during an automatic piloting of a vehicle delivering requests for stopping and relaunching of the vehicle, engine torque, braking and gear change setpoints (ADAS M, ADAS F). Supervision is established with identification of a stop phase by association of a stop request, a zero torque setpoint and the braking in force. In the stopping phase, a drag reduction inhibition (ADAS red tr) is performed, resulting in a gearbox neutral coupling instruction, then, in the relaunch phase, following a relaunch request and an instruction of non-zero torque, a suspension of the inhibition (ADAS red tr) is emitted, resulting in a coupling instruction corresponding to the passage of a first gearbox ratio.
