Title: IN-PROCESS COMPUTER-CONTROLLED ACTIVE REAR AXLE KINEMATIC CHAIN
Abstract:
In-process computer-controlled active rear axle kinematic chain of a motor vehicle, the rear wheels of which are also steered by means of an electronically controlled control element. For automatic control of the rear wheels, the in-process computer makes allowance for the corresponding steering angle of the front wheel and/or values derivable therefrom, a possibly speed-dependent correction time constant, a possibly speed-dependent delay time constant; and a possibly speed-dependent delay time constant, and a possibly speed-dependent concomitant steering factor. The in-process computer processes parameters derived from scanning values and which correlate at least with these angles, according to a difference calculus equation, not according to a differential equation to be solved iteratively, and supplies the reference values for the rear axle or rear wheel steering angle and/or reference values derived therefrom to the control element.
