摘要: A wheeled vehicle is equipped with a feedforward steering control system which steers the vehicle through front or rear road wheels in accordance with a driver's steering input such as an angular displacement of a steering wheel, and a negative feedback system which senses a turning behavior of the vehicle such as a yaw rate or a lateral acceleration, and steers the vehicle through the front or rear wheels in such a negative direction as to reduce the turning behavior. The feedforward system may control the angular direction of the front or rear wheels in accordance with a linear combination of the steering input and the time derivative of the steering input, or may control the angular directions of both of the front and rear wheels in accordance with different transfer functions between the steering input and the front and rear wheel angles. The negative feedback system is combined with the feedforward system in various ways to provide desired characteristics of the turning behavior. The negative feedback quantity determined by the negative feedback system may be proportional to the sensed turning behavior, or may be determined in accordance with the difference between the sensed turning behavior, and the reference turning behavior calculated from the vehicle speed and steering input.

摘要: In an electric vehicle driven by an electric motor, a battery accumulator supplies electricity to the electric motor and a plurality of auxiliaries. A generating unit generates electricity in order to charge the battery accumulator. A detector unit detects at least one of various running conditions of the vehicle. A control unit supplies the electricity from the generating unit directly to the electric motor when the detected running condition indicates an overload condition, and gradually reduces the electricity supplied to the auxiliaries.

摘要: A method of controlling an automotive vehicle is disclosed whereby a steering characteristic of the vehicle is automatically adjustable to a feature of the driver's steering the vehicle. The feature of the driver's steering the vehicle is detected in terms of a driver's technique or habit in manipulating a steering wheel or a motion characteristic of the vehicle such as a yaw rate or a lateral acceleration resulting from a driver's manipulating the steering wheel. A pair of steerable road wheels, such as a pair of front road wheels, are steered through an angle which is proportioned to an angle through which the steering wheel is manually turned at a ratio which is variable with variation in the feature of the driver's steering the vehicle.
