Abstract
A drive device includes: a control storage unit of a current value of a control signal indicating a drive state of each of loads; a drive unit of the switches according to the current value; an acquisition unit of a current drive state of each load; a determination storage unit of a transition determination value; and a determination unit that compares a correlated drive state of each load correlated with the current value with the transition determination value, and determines that the current value is abnormal when the correlated drive state and the transition determination value satisfy a predetermined corresponding relationship.
Claims10
A drive device that drives a plurality of loads by controlling a plurality of semiconductor switches corresponding to the loads, the drive device comprising:
- a control storage unit that stores a current value of a control signal including a signal indicating a drive state of each of the loads;
- a drive unit that controls the plurality of semiconductor switches according to the current value of the control signal;
- an acquisition unit that acquires a current drive state indicating the drive state of each of the loads at a present time;
- a determination storage unit that stores a transition determination value for determining whether the current value of the control signal stored in the control storage unit is abnormal, the transition determination value being correlated with a driving transition from the current drive state;
- and
- a determination unit that compares a correlated drive state of each of the loads correlated with the current value of the control signal stored in the control storage unit with the transition determination value, and determines that the current value of the control signal is abnormal when the correlated drive state and the transition determination value satisfy a predetermined corresponding relationship.
