ELECTRIC VEHICLE MOTOR TORQUE SAFETY MONITOR |
| 摘要 |
A safety system for an electric motor controller is provided. The safety system includes a torque safety monitor having a first processor distinct from a second processor of a main motor controller. The first processor is configured to one of decrease or shut down AC (alternating current) power, sent from a DC/AC (direct current to alternating current) inverter to an electric motor, in response to an estimated torque of the electric motor differing from a commanded torque associated with the main motor controller by more than a set amount. |
