Abstract: An object detecting apparatus includes a first transmission and reception unit having a first transmitter and a first receiver, a second transmission and reception unit having a second transmitter and a second receiver, and a failure judging section. The first receiver produces a first output signal corresponding to a transmission wave, which is transmitted directly from the second transmitter to the first receiver. The second receiver produces a second output signal corresponding to a transmission wave, which is transmitted directly from the first transmitter to the second receiver. Using at least one of the first output signal and the second output signal, the failure judging section judges whether a failure of the first transmitter or the second receiver has occurred, or judges whether a failure of the first transmission and reception unit or the second transmission and reception unit has occurred.

Abstract: 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.

Abstract: 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.
