摘要:
A method of controlling an actuator includes developing a sequence of actuation commands S(tx)=C(tx, tx), C(tx, tx+1), . . . , C(tx, tx+n) obtained from data sensed before time tx for controlling the actuator at different time intervals (tx, tx+1), (tx+1, tx+2), . . . , (tx+n−1, tx+n). The sequence of actuation commands is transmitted to and stored in memory of an actuation ECU, which then applies the actuation command for time interval (tx, tx+1). If a fault affects a sensor, a control ECU or data communication therebetween, the actuation ECU will not receive an updated sequence of actuation commands S(tx+1) at time tx+1. If the updated actuation command sequence, the actuation ECU applies the actuation command for the time intervals (tx+1, tx+2), . . . , (tx+n−1, tx+n) from the sequence of actuation commands S(tx) that is stored in the memory of the actuation ECU.
