    摘要: An acceleration control system stores a target acceleration calculation equation acquired by transforming an equation that expresses that a product of the differentiation of the square power of the speed and the environmental factor αenv represents a sensed value ε of acceleration. A surrounding environment monitor device detects surrounding bodies present in the forward periphery of the vehicle, and an environmental factor calculation unit calculates the environmental factor αenv by using the detected positions of the surrounding bodies. A target acceleration setting unit successively sets target accelerations aref in compliance with the target acceleration calculation equation by using the environmental factor αenv. The acceleration is executed to match the driver's feeling.

    摘要: 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.

Locus data representing a plurality of position coordinates of the GPS receiver during a past specified period is generated based on a position coordinate acquired. A road section traveled by the GPS receiver during the past specified period is estimated based on road data stored and a position coordinate acquired. A bias error of a position coordinate measured by the GPS receiver is estimated based on position coordinates at a plurality of points in a road section estimated and position coordinates at a plurality of points represented by the locus data. A position coordinate measured by the GPS receiver is corrected based on a bias error estimated and outputted.

    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.
