Control system for electrified vehicle

A control system for an electrified vehicle, the control system comprising:

• an electric power control device that adjusts electric power to be supplied to a motor of the electrified vehicle;
• a first control device that outputs a first command value indicating a target output of the motor;
• and
• a second control device configured to be communicable with the first control device, the second control device outputting a driving signal to the electric power control device based on the first command value output from the first control device, wherein
• the second control device includes
• a processor configured to be communicable with the first control device, the processor programmatically processing the first command value output from the first control device, the processor outputting an operation command value for the motor, and
• a logic circuit including a first circuit structure that converts the operation command value output from the processor to the driving signal,
• in a case where a limp home mode that causes the electrified vehicle to limp home is executed, the first control device outputs a second command value based on the limp home mode to the logic circuit instead of the first command value, and
• the logic circuit further includes
• a second circuit structure that converts the second command value output from the first control device to a limp home driving signal,
• a third circuit structure that receives the driving signal resulting from the conversion by the first circuit structure and the limp home driving signal resulting from the conversion by the second circuit structure, and alternatively outputs one of the driving signals, and
• a fourth circuit structure that receives the output made by the third circuit structure and a cutoff command for the electric power control device, and cuts off the output made by the third circuit structure while receiving the cutoff command.
