Abstract: A method for a power steering system for empirically determining at least one property of the system, power steering system including at least one steering wheel, a steering mechanism provided with a rack, and at least one assist motor, method having, outside a steering phase during which the power steering system is assigned to the driving of a vehicle in order to cause vehicle to follow a trajectory which is determined as a function of the situation of vehicle with respect to its environment, a step (a) of automatically activating the assist motor, during which step a computer is used to automatically generate and apply to the assist motor; at least one indicator parameter which is specific to the response by the powersteering system to the automatic activation of the assist motor and which is characteristic of the desired property.

Abstract: A method for characterizing a power steering system for empirically determining at least one property of the system, the power steering system including at least one steering wheel, a steering mechanism provided with a rack, and at least one assist motor, the method including, outside a steering phase during which the power steering system is assigned to the driving of a vehicle in order to cause the vehicle to follow a trajectory which is determined as a function of the situation of the vehicle with respect to its environment, a step (a) of automatically activating the assist motor, during which step a computer is used to automatically generate and apply to the assist motor, without requiring any external action on the steering wheel, an activation instruction that follows one or more cycles referred to as pre-established exploration cycles for measuring.

Abstract: A power steering system having at least one steering wheel, steering mechanism provided with rack, and at least one servo motor, the method having, outside steering phase during which power steering system is assigned to driving of vehicle to cause vehicle to follow trajectory which is determined as function of the situation of vehicle with respect to its environment, step (a) of automatically activating the servo motor, during which step computer is used to automatically generate and apply the servo motor, without requiring any external action on steering wheel, activation instruction that follows one or more cycles referred to as pre-established exploration cycles in order to measure, during at least one exploration cycle or at the end of at least one exploration cycle, at least one indicator parameter which is specific to response by power steering system to automatic activation of servo motor and which is characteristic of desired property.
