Device for the operation of an active steering system of a motor vehicle and method for the operation of an active steering system of a front axle of a motor vehicle

摘要

Device for the operation of an active steering system of a motor vehicle, wherein by means of this active steering journey situation by means of a steering system as a function of the composition ratio of the motor vehicle by means of superposition of a calculated correction angle by means of a vehicle controller can be varied, characterized in that the device has a controller (130), which is configured for this purpose, one of a driving dynamics - controller (120) are supplied by the requirement value (δf_yfr) in the correction angle (δδ) by means of carrying out the following steps of transforming:a) determining a force requirement value (f_yfr) for a lateral total force acting on the front axle as a sum of a working point, which is produced by a driver - force requirement value (f_yfdri) is defined, and the of the driving dynamics - controller (120) are supplied by the requirement value (δf_yfr) according to the equationF_yfr = F_yfdri + Δf_yfrwhere f_yfr the force requirement value, δf_yfr the of the driving dynamics - controller (120) and f are supplied by the requirement value_yfdri the driver - force requirement value designate;b) calculating a steering angle requirement value (α_fr) from the force requirement value (f_yfr), the calculation of up to a threshold value for the force requirement value by inversion of a force - slip angle - of the characteristic curve of the front vehicle axis and..
