Abstract

The invention discloses a variety of technologies related to transmission system control. In one embodiment, the communication between the controller and the sub-modules of the transmission system in the first mode of operation takes place via a first communication channel, and optionally additionally via a second communication channel. In the second operating mode, when the first communication channel fails, the communication with the submodules of the drive train takes place via the second communication channel.

Description

technical field [0001] The present application relates to methods and devices relating to controlling a transmission system or parts thereof. Background technique [0002] A transmission system, such as those used in automotive applications, may include various devices, such as electric motors, which may be controllable to ensure proper operation of the transmission system. For example, an electric motor may include multiple coils, and proper current must be supplied to the coils to ensure proper operation of the motor. The current may for example comprise a multi-phase alternating current (AC) generated by a suitable direct current / alternating current (DC / AC) converter based on a DC voltage provided in an automotive environment such as a car. Proper control of the DC / AC conversion or other parameters involved in operating the motor ensures that the motor operates as desired. [0003] Controlling the operation of the transmission system may involve the use of communication...
