Embodiment Construction

[0057] exist figure 1 A safety system 10 for a steering system 2 of a vehicle 1 is shown in FIG. The safety system 10 can comprise an actuator 5 for generating a torque up to the maximum torque on the steering control element 3 of the vehicle 1 when the maximum torque is released. In other words, the torque cannot exceed the maximum torque here. In this case, the actuator 5 is designed, for example, as an electric motor which applies a torque and / or a torque in the form of a steering assist to the steering element 3 . The steering element 3 is designed, for example, as a steering wheel 3 and can be used as an entry and exit assistance as long as a maximum torque is applied for locking the steering element 3 or the steering wheel 3 . However, for normal use of the steering element 3 , this maximum torque should be limited in order to prevent locking of the steering element 3 . Correspondingly, the actuator 5 can be designed for this purpose to (only) generate a torque that i...

Abstract

A method for operating a steering system (2) of a vehicle (1), wherein an actuator (5) is provided for generating a moment at a steering handle (3) of the vehicle (1), wherein the following steps arecarried out: generating (101) the moment up to a maximum moment if the maximum moment is enabled, and up to a lower limited moment if the maximum moment is limited, identifying (102) a vehicle situation of the vehicle, enabling (103) the maximum moment if the vehicle situation is identified as being a boarding and / or deboarding situation in order to brace the steering handle (3), and limiting (104) the maximum moment if the vehicle situation is identified as being driving operation of the vehicle (1).

Description

technical field [0001] The invention relates to a method of operating a steering system. In addition, the invention relates to a security system and a computer program. Background technique [0002] It is known from the prior art to use an additional actuator in the steering system of a vehicle which exerts a restoring torque on the steering wheel. The force feedback steering wheel can also be said in this respect. In this way, the driving comfort, in particular in steer-by-wire systems, can be improved. Steering commands are transmitted electrically in the steer-by-wire system. Accordingly, it can be provided that there is no mechanical connection between the steering wheel and the steering gear. There are therefore high safety requirements with respect to the functionality of this type of steering system. [0003] Implementing high safety requirements can be technically complex compared to actuators or force feedback steering wheels. In particular during driving, it ...
