An acceleration control system controls acceleration of a vehicle to match the driver's feeling. In this control, the vehicle is controlled so that acceleration remains constant at the initial stage and then a differentiated value of a square power of a vehicle speed remains constant. This control is based on the finding of a normal acceleration operation attained by a driver. A linear relation exists between the acceleration in the initial stage of acceleration and the differentiated value of the square power of the speed. Switching of control from the constant acceleration to the constant differentiated value of the square power of the speed is made at a change-over speed determined by the linear relation.
摘要:
In an OFDM type radio transmitter, an orthogonal modulator performs an orthogonal modulation of an I-component and a Q-component, an orthogonal component output circuit produces the I-component and the Q-component in accordance with set values, and a correction circuit sets the I-component and the Q-component to zero. The correction circuit further corrects offset values of the I-component and the Q-component by way of the orthogonal component output circuit to minimize an output power of the orthogonal modulator. The number of times of changing the set values of the orthogonal component output circuit is limited to predetermined values in correcting the offset values.

An information storage apparatus recognizes a traffic sign on a road expressed by a road surface image, and stores recognized traffic sign in association with its position information in a hard disk drive. By recognizing and storing information on the traffic sign in combination with the position information for the sake of traffic safety, information coverage in terms of traffic safety is updated to the most up-to-date condition for roads in the entire country.
