摘要： PROBLEM TO BE SOLVED: To provide a motor-driven power steering device, enabling accurate detection of abnormality even if abnormality occurs in a rotation angle sensor and a yaw rate sensor so as to perform return control without lowering of steering feeling. SOLUTION: A CPU computes a neutral angle θc from a relative steering angle θa obtained from a motor M by a relative angle computing part 60 according a rotation angle sensor E and a yaw rate Y detected from a yaw sensor 70 by a neutral estimation computing part 282A, and obtains an absolute steering angle θ according to these by a handle absolute angle computing part 281. When both θ and Y are monitored and only one of them changes, abnormality is decided by an abnormality determination part 80, handle return control at handle return control parts 1, 2 (26, 28) controlling depending on θ and angular speed ω is suspended. Therefore, it is possible to prevent lowering of steering feeling caused by wrong assist due to disconnection of a sensor. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To properly distribute a braking force to each wheel according to a static load of each wheel by properly estimating the static load of each wheel with an inexpensive and simple constitution.
SOLUTION: A braking stiffness of each wheel (such as FR) is calculated on the basis of output of a wheel speed sensor (WS1 and the like), to estimate the static load of each wheel based on the calculation results while a vehicle is linearly traveling at approximately constant speed. According to the static load, a braking force of each wheel is controlled to adjust distribution of the braking force. A dynamic load between respective wheels may be calculated on the basis of detection results of a lengthwise acceleration sensor (XG) and a lateral acceleration sensor (YG) and the estimation result of the static load, to control the braking force of each wheel according to the dynamic load. Only when a pneumatic pressure of a tire is detected and it is within a predetermined pressure range, estimation of the static load may be permitted.
