Abstract:
1. An error detecting device of a dual controller system comprising: a first controller receiving a sensing data from a sensor to calculate and generate a first data and outputting a final data if an error is not detected by comparing the first data with a second data transmitted from a second controller; a CAN transceiver receiving the final data from the first controller and transmitting the final data through a CAN bus; and the second controller receiving the sensing data from the sensor to calculate and generate a second data and transmitting to the first controller an interrupt signal which prevents an output of the final data if an error is detected by comparing the second data with the final data fed back from the CAN transceiver, wherein: the first controller comprises a first calculating unit which receives the sensing data and calculates and generates the first data, a first comparing and controlling unit which compares the first data with the second data to detect the error and transmits an output control signal to a first CAN module if the error is not detected, and the first CAN module which operates according to the output control signal, processes the first data according to a CAN protocol and transmits the final data; and the second controller comprises a second calculating unit which receives the sensing data and calculates and generates the second data, a second CAN module which processes the final data fed back from the CAN transceiver according to the CAN protocol and transmits a third data, a second comparing unit which compares the second data with the first data transmitted from the first controller to detect the error and compares the second data with the third data transmitted from the second CAN module to detect the error, and a second control unit which transmits the interrupt signal to the first controller if the error is detected at the second comparing unit.
