Title:
DRIVING ELECTRIC MOTOR CONTROL SYSTEM AND METHOD FOR ENSURING SAFETY THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/204118
Kind Code:
A1
Abstract:
A driving electric motor control system and a method for ensuring the safety thereof, which belong to the field of electronic circuits. The system comprises: a DSP, which is electrically connected to a gate driving logic control module (23) and is used for acquiring a gate driving control right by interacting with the gate driving logic control module (23); a CPLD, which is electrically connected to the DSP and the gate driving logic control module (23) and is used for taking over the gate driving control right by interacting with the gate driving logic control module (23) when the DSP is in a fault state; the gate driving logic control module (23), which is electrically connected to a gate driving circuit module (24) and is used for realizing control, by the DSP and the CPLD, over the gate driving control right and for transmitting, to the gate driving circuit module (24), a control signal output by the DSP or the CPLD in response to the gate driving control right; and the gate driving circuit module (24), which is electrically connected to an electric motor and is used for driving the electric motor in response to the control signal. By means of the method, double-point control over a gate driving control right can be realized.
