A motor system fault handling method and processor

Abstract

The invention discloses a motor system fault processing method and a processor. The motor system fault processing method includes: detecting a basic operation parameter of a motor controller and a basic operation parameter of a motor, judging if the basic operation parameter of the motor controller and the basic operation parameter of the motor meet a preset fault condition, generating fault information and sending the fault information to a controller of a whole vehicle under the condition that at least one of the basic operation parameter of the motor control and the basic operation parameter of the motor meets the preset fault condition, finally receiving control commands sent by the controller of the whole vehicle, and generating trigger commands corresponding to the control commands. A motor system is used as a sub-system of the controller of the whole vehicle, the controller of the whole vehicle generates control commands to control the motor system to make corresponding processing movement according to fault information and by combining operation states of other sub-systems in a whole vehicle system. The motor system is prevented from conducting corresponding processing on faults independently, and planning, controlling and management of safety of the whole vehicle from the perspective of the whole vehicle system are achieved.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis of a new energy vehicle drive motor system, and more specifically, relates to a motor system fault processing method and a processor. Background technique [0002] As the global awareness of energy saving and environmental protection gradually increases, new energy vehicles will gradually replace internal combustion engine vehicles as the ultimate development direction of the industry. As the key power system components in new energy vehicles, automotive motors and their motor controllers are closely related to the performance and driving safety of the vehicle. Therefore, real-time detection of various faults in the motor system during the operation of the vehicle system, and accurate and timely processing according to the corresponding fault type and fault level can avoid damage to the components of the motor system itself and avoid affecting the vehicle system. Safety. [0003] At pres...
