Control Device and Method for Operating an Electric Motor, in Particular of a Steering System - A simplified explanation of the abstract
This abstract first appeared for US patent application 18323057 titled 'Control Device and Method for Operating an Electric Motor, in Particular of a Steering System
Simplified Explanation
The patent application describes a control device for an electric motor, specifically for a steering system.
- The control device includes a power electronics, a primary driver unit, and a secondary driver unit.
- The primary driver unit is responsible for normal operation of the power electronics.
- The secondary driver unit is connected in parallel to the primary driver unit and is activated when a malfunction or failure occurs in the primary driver unit.
- The secondary driver unit has a power source with adjustable current strength to control the switching state of circuit breakers in the power electronics.
- In the normal operating state, the power source is set to a first value below a limit value.
- In the fault operating state, the power source is set to a second value above a different limit value.
Original Abstract Submitted
A control device for operating an electric motor, in particular a steering system, includes a power electronics, a primary driver unit provided for actuating the power electronics in a normal operating state, and a secondary driver unit connected in parallel to the primary driver unit and provided for actuating the power electronics in at least one fault operating state in which a malfunction and/or failure of the primary driver unit occurs. The secondary driver unit comprises a power source having an adjustable current strength for controlling a switching state of at least one circuit breaker of the power electronics. An absolute value of the power source in the normal operating state is set to a first value which is below a first limit value, and in the at least one fault operating state it is set to a second value which is above a second limit value.
