A frequency control apparatus includes: an input operation unit which detects a presence/absence of an input of a predetermined operation by an operator; and a control unit which, when the input of the predetermined operation by the input operation unit is detected, calculates radio frequencies, each of the radio frequencies being where a minimum value of differences with respect to multiplied frequencies of a current drive frequency of a device is less than or equal to a predetermined value, and which changes the current drive frequency of the device so that minimum values of differences between the calculated radio frequencies and multiplied frequencies of the changed drive frequency are greater than or equal to a predetermined value. The control unit changes the drive frequency to lessen a change width before and after the change by either increasing the drive frequency or decreasing the drive frequency.

A rectifying section and a DCDC converter which lowers an input DC voltage and then outputs the voltage are disposed between an AC generator and a load When the output voltage Vt of the AC generator is gradually lowered with starting from E the output power P is increased, and is maximum at Vt&equals;V When the output voltage Vt is further lowered, the output power P is reduced. As an operating point at which the same output power P is obtained, there are a point of Vt&equals;V and that of Vt&equals;V The operation of the DCDC converter is controlled so as to operate at the point of Vt&equals;V where the output current I is lower.

Electric power supply system

A control system for an automatic vehicle transmission, in which the running resistance acting on the vehicle and the driving force generated by the vehicle are calculated, and a slope of a road on which the vehicle travels is estimated based on at least the calculated running resistance and the driving force. The vehicle running state is then discriminated by comparing the estimated slope with a predetermined value. The maximum driving force to be generated by the vehicle at the current gear ratio is calculated to determine a driving force difference from the calculated driving force and the gear ratio of the transmission is determined such that the driving force difference is a predetermined value in response to the discriminated running state, thereby enhancing the drivability.

Control system for automatic vehicle transmission

Provided is an object detection apparatus, which includes a light emission device irradiating an object with light at a wavelength having less disturbance, and a light reception device including a filter that permits light having the aforementioned wavelength to pass, for receiving reflected light from the object. When the disturbance is sunlight, the light having a wavelength whereat the spectral radiative illuminance is damped is employed in accordance with the spectral characteristic of sunlight. In one embodiment, an object detection apparatus, which is mounted in a vehicle, employs, as an object, the eyes of a crew member in the vehicle, and obtains reflected images of the crew member's corneas and retinas to calculate the observed point viewed by the crew member.
