摘要： A driving support control apparatus using an electric power steering mechanism that improves followability to a target track and safety of steering operation by adapting information of a steering torque to a driver's characteristic on the basis of conditions for enhancing predictability of a vehicle track. The driving support control apparatus includes: a SAT estimating section that estimates a self-aligning torque; a SAT transfer characteristic control section that corrects the self-aligning torque in order to make a time constant of a self-aligning torque transfer characteristic equal to a desired value, and compensates the steering torque; a disturbance sensitivity control section that suppresses a disturbance included by the self-aligning torque, and compensates the steering torque; and a vehicle characteristic compensation control section that compensates the steering torque in accordance with an actual steering angle so that a vehicle characteristic becomes a primary delay characteristic.

摘要： An in-vehicle electronic control device for diagnosing the details of an abnormality of a microcomputer appropriately is provided. A monitoring function for detecting a malfunction by monitoring input/output of a main function of a hardware part and a monitoring function for detecting an abnormality by monitoring the calculating result of a main function in a software part are provided in a microcomputer. The main function to be monitored is implemented with a different structure than the malfunction/abnormality monitoring function. Furthermore, a malfunction processing circuit for monitoring an abnormality of the microcomputer is provided outside the microcomputer.
