Title:
電動パワーステアリング装置
Document Type and Number:
Japanese Patent JP5382229
Kind Code:
B1
Abstract:
When a steering torque sensor fails, a time delay setting section 90 calculates delayed lateral acceleration LAlim by delaying lateral acceleration LA. A lateral acceleration upper limit restricting section 82 calculates restricted lateral acceleration LA2 by restricting the upper limit of the lateral acceleration LA by the delayed lateral acceleration LAlim. An assist torque calculation section 83 calculates a target assist torque Ta2 on the basis of the restricted lateral acceleration LA2 such that the target assist torque Ta2 increases with the restricted lateral acceleration LA2. Thus, it is possible to properly delay steering assist in relation to detection of the lateral acceleration LA, whereby slippage of a vehicle due to excessive turning of a steering wheel 11 is suppressed.
