摘要:
A drive-force distribution controller for a four-wheel-drive vehicle having a torque distribution unit configured to distribute an output torque transmitted from a prime motor to a first set of wheels to a second set of wheels. The drive-force distribution controller includes a first judging device for judging which of the first set is an inner wheel with respect to a turning of the vehicle, a second judging device for judging whether the turning of the vehicle is a tight turn, a third judging device for judging whether the inner wheel is slipping, a fourth judging device for judging whether an outer wheel of the first set of wheels is slipping, and a controlling device for controlling the torque distribution unit.

摘要:
Ink reservoirs are provided in a channel substrate correspondingly to various colors of ink. Two or more dummy nozzles which are not used for performing printing/recording are provided between printing/recording nozzles for jetting ink of different colors. A space wide enough to disposed therein at least two nozzles is provided between the dummy nozzles. Consequently, adjacent and different-color ink is not mixed, and nozzles having unstable operation and disposed near the side walls of the ink reservoirs are not used for performing printing/recording, so that images of high quality can be obtained.

There is disclosed a device for controlling steering force in a power steering apparatus having an electromagnetic control valve according to road and driving conditions. The device includes a car speed sensor, a steering angle sensor, first arithmetic means, second arithmetic means, correcting means, control current arithmetic means and controlling means. The first arithmetic means computes a driving condition index by using car speed information. The second arithmetic means computes a road condition index by using steering angle signals. The correcting means converts the driving condition index into a correction driving condition index which takes any one of several stepwise-varied values. The control current arithmetic means computes an output control current value applied to electromagnetic control valve by the controlling means. The device further includes means for detecting lateral acceleration utilized for controlling the steering force.
摘要:
A motor vehicle is provided with a driving status discrimination device, which includes a steering angle sensor for detecting the rotational angle of a steering wheel and a microcomputer for reading and processing the steering angle signal each time the vehicle runs a predetermined distance. The microcomputer identifies one of steering angular ranges of intervals to which each detected steering angle belongs so as to record the frequency at which the steering wheel was turned to each steering angular interval. The microcomputer modifies the frequency for each steering angle interval with a weighting coefficient determined for the steering angular interval and then, calculates a total or integrated value of the modified frequencies for the steering angular intervals. Further, the microcomputer discriminates town street driving from mountain road driving based upon the integrated value so that the assisting power generated by a power steering mechanism of the motor vehicle can be controlled based upon the result of such discrimination.

The present invention provides a curable polysiloxane composition which is excellent in light resistance (particularly ultraviolet resistance) and adhesion and has a sufficient heat resistance/hydrothermal resistance and film-forming property and which generates little foaming at curing and does not generate cracks, peeling, coloring, and foaming even when used for a long period of time. A curable polysiloxane composition which comprises a specific hydrosilyl group-containing polysiloxane compound, a specific polysiloxane compound comprising two or more silanol groups in one molecule, and a dehydrogenative condensation reaction catalyst.
摘要:
In an electric power steering system, when a motor rotation angular speed ω and a motor rotation angular acceleration α of a steering assisting motor both exceed corresponding predetermined values ωs and αs, respectively, an abnormal external force application-determining section determines that an external force equal to or greater than a predetermined value is applied to a steering mechanism, and sets an abnormal external force application determination flag (FLG) to 1. When the abnormal external force application determination flag (FLG) is 1, a d-axis electric current command value-calculating section activates a motor rotation angular speed-reducing section and performs field-strengthening control based on a motor rotation speed/d-axis electric current command value map.
