Vehicle trailer equipped with an additional traction system, vehicle with said trailer, and method for managing the additional traction system

摘要

Motor vehicle with trailer comprising an additional traction system comprising: electric motors (1, 2) applied to the wheels of at least one axle of the trailer; a loading cell (12) measuring the tractive or thrust force exerted on the trailer by the vehicle; a group of traction batteries (4); an electronic regulator (3) which regulates the charging and the power supplied by the group of traction batteries (4) and regulates the power supplied to the motors. The electronic regulator (3) controls the independent activation of the motors providing traction torque or braking torque in order to minimize said tractive or thrust force to approximate the performance of the vehicle to the situation wherein the trailer is absent.
