Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/060546
Kind Code:
A1
Abstract:
A first control unit (57) is activated by being supplied power from a first power supply pathway (51), and put in an activated state. A second control unit (67) is supplied power from a second power supply pathway (61) separate from the first power supply pathway (51). The first power supply pathway (51) is provided with a power source switch (52). When a prescribed switch command is a connection command (C), the power source switch (52) switches ON and enables energization of the first power supply pathway (51). When the switch command is a disconnection command, the power source switch (52) switches OFF and disables energization of the first power supply pathway (51). The first control unit (57) emits an activation signal (α) indicating whether the first control unit (57) is in an activated state or a stopped state. The second control unit (67) assesses the power source switch (52) to be abnormal if the activation signal (α) indicates a stopped state while the switch command is a connection command (C), or if the activation signal (α) indicates an activated state while the switch command is a disconnection command (C).
