Abstract
A drive device includes: a receiving unit of a load control signal indicative of a drive state of each load; a control storage unit of the load control signal; a drive unit of the switches according to the load control signal; an acquisition unit of a current drive state of each load at a present time, or a current vehicle state; 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 load control signal with the transition determination value, and determines that the load control signal is abnormal when the correlated drive state and the transition determination value satisfy a predetermined corresponding relationship.
Claims12
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 receiving unit that receives a load control signal including a signal that indicates a drive state of each load from an external control device;
- a control storage unit that stores the load control signal received by the receiving unit;
- a drive unit that controls the plurality of semiconductor switches according to the load control signal stored in the control storage unit;
- an acquisition unit that acquires a current drive state which is the drive state of each load at a present time, or a current vehicle state;
- a determination storage unit that stores a transition determination value for determining whether the load control signal received by the receiving unit is abnormal, the transition determination value being correlated with a driving transition from the current drive state or the current vehicle state;
- and
- a determination unit that compares a correlated drive state of each of the loads correlated with the load control signal received by the receiving unit with the transition determination value, and determines that the load control signal received by the receiving unit is abnormal when the correlated drive state and the transition determination value satisfy a predetermined corresponding relationship.
A driving system comprising:
- a drive device that drives a plurality of loads by controlling a plurality of semiconductor switches corresponding to the loads;
- and
- a control device that is configured to communicate with the drive device, wherein:
- the control device includes:
- a transmission unit that transmits a load control signal including a signal indicating a drive state of each of the loads.
- the drive device includes:
- a receiving unit that receives the load control signal;
- a control storage unit that stores the load control signal received by the receiving unit;
- a drive unit that controls the plurality of semiconductor switches according to the load control signal stored in the control storage unit;
- an acquisition unit that acquires a current drive state indicating the drive state of each of the loads at a present time or a current vehicle state;
- a determination storage unit that stores a transition determination value for determining whether the load control signal received by the receiving unit is abnormal, the transition determination value being correlated with a driving transition from the current drive state or the current vehicle state;
- and
- a determination unit that compares a correlated drive state of each of the loads correlated with the load control signal received by the receiving unit with the transition determination value, and determines that the load control signal received by the receiving unit is abnormal when the correlated drive state and the transition determination value satisfy a predetermined corresponding relationship.
