Method for calculating e.g. wheel speed signal for powertrain of motor car, involves computing speed signal by controller based on computed default moment and driving resistance, and receiving moment indication by control circuit

摘要

The method involves computing a speed signal e.g. wheel speed signal (omega-rad), by a controller (K) based on a computed default moment and driving resistance, where the driving resistance acts against the default moment. A signal resulting from comparison of the computed speed signal and a measured speed signal is received by the controller. A moment indication (Md) is received by a control circuit of the controller, and a signal coming from an output-side of the controller is made to overlap with the indication. An independent claim is also included for a device for calculating a speed signal for a powertrain of a motor car.
