摘要： In an automatic driving apparatus, a storage unit is responsive to a storing mode signal for storing as model driving data steering and running states of the vehicle corresponding to elapsed time in a storing mode. In response to an automatic driving mode signal, a setting unit compares the steering and running states stored in the storage unit and steering and running states of the vehicle detected in an automatic driving mode so as to set at least one automatic steering state data. In the automatic driving mode, the model driving data stored in the storage unit can be reproduced with the vehicle's steering system set to an automatically operating state, and the vehicle can be steered automatically in accordance with the model driving data, so that highly convenient, efficient and reliable automatic driving are achieved in automatic garaging of the vehicle etc. with a simple structure that would otherwise require high-level skill of the vehicle driver. The apparatus further includes an electric power steering apparatus that is used for controlling steering of the vehicle on the basis of the automatic steering state data supplied by the setting unit. The use of the electric power steering apparatus substantially simplifies the structure of the automatic driving apparatus.

摘要： In a steering control system for a motor vehicle, the magnitude of the steering assist torque is reduced from a normal value by a value depending on the ratio of the steering angle to a maximum permissible steering angle which is determined according to the frictional coefficient between the road surface and the road wheels so that excessive steering, which may otherwise occur on a slipper road surface, can be avoided. Additionally, the value by which the steering assist torque is reduced is increased with an increase in the steering speed so that a certain damping effect may be achieved in the system. This is particularly beneficial in preventing any ill effect which may arise when the steering wheel has a large mass of inertia, for instance by being equipped with an air bag system.
