Abstract

This electric vehicle comprises a dog clutch (48) with a first set of teeth (56) driven by an electric motor and a second set of teeth (58) rotatably coupled to a shaft (26), and an actuator (54) to engage the dog clutch. A method for engaging the dog clutch comprises, in this order:- detecting a blocking of the dog clutch in a teeth-to-teeth configuration while the actuator tries to engage the dog clutch and while the shaft is rotatably decoupled from output components of the vehicle,- rotating the first set of teeth in a first direction (R1), to drive the shaft in rotation by friction between the sets of teeth, and- rotating the first set of teeth in a second direction (R2) opposite to the first, so that the first set of teeth slip against the second set of teeth, enabling the actuator to fully engage the dog clutch.
