Document Type and Number:
Japanese Patent JP7028135
Kind Code:
B2
Abstract:
To provide a device for determining failure of vehicle control, capable of appropriately determining the presence or the absence of the failure of the vehicle control.SOLUTION: The device for determining failure of vehicle control comprises: a relay circuit; and a control part. The control part executes a failure determination process of the relay circuit. The relay circuit comprises: a power supply circuit; and a relay switch. The relay switch comprises: a first contact point; a second contact point; an output side contact point; a coil; and a movable piece. The control part determines that the relay switch is normal when a potential of the output side contact point when the coil is in a non-conductive state matches a first target value, and the potential of the output side contact point when the coil is in a contact state matches a second target value, and determines that there is something wrong with the relay switch when at least one of them does not match the target value.SELECTED DRAWING: Figure 4
