Application Number: JP,2023-042993
Category (FI): B62D6/00,B62D5/04
Stage: PROBLEM TO BE SOLVED: To prevent erroneous determination of abnormality determination at the time of sudden steering operation in a motor control device including two redundant systems of a steer-by-wire type steering device.SOLUTION: When a first system L1 and a second system L2 are normal, a third processor 68 outputs a first steering current command value It1. When there is a deviation between the first steering current command value It1 and a second steering current command value It2, the third processor 68 outputs the second steering current command value It2. When sudden steering operation is determined, the third processor 68 outputs the first steering current command value It1 irrespectively of whether or not there is a deviation between the first steering current command value It1 and the second steering current command value It2. An erroneous determination due to the deviation between the first steering current command value It1 and the second steering current command value It2 accompanied with the sudden steering operation is prevented.SELECTED DRAWING: Figure 3 (Grant)
