A method for disconnecting an electrical machine connected with the wheels of a vehicle's drive axle by means of a dog clutch having intermeshing couplers includes, upon receipt of a command to disengage, two successively activated steps. In the first step, a torque equal to a calibrated threshold of a target torque (d) is applied to the electrical machine so to effect a zero torque between the couplers. During this step, a dog clutch actuator is deactivated so to allow the dog clutch to disengage from the electrical machine as quickly as possible. Next, a torque having a value determined according to a slope whose value ranges from the calibrated threshold of the target torque (d) to zero is applied to the electrical machine.
