    Abstract: PROBLEM TO BE SOLVED: To provide a navigation device capable of avoiding execution of processing based on an acceleration measuring result having poor accuracy, when the accuracy of the acceleration measuring result by an acceleration sensor is poor. SOLUTION: When a driving diagnosis scene, such as an entering scene of own vehicle into a crossing or an entering scene into a main line of a highway, is generated, the navigation device determines accuracy of an acceleration of own vehicle measured by the acceleration sensor based on a difference between the acceleration of own vehicle measured by the acceleration sensor and an acceleration of own vehicle specified based on vehicle speed and angular speed of own vehicle (S115), and the navigation device performs driving diagnosis relative to driving of own vehicle based on the acceleration of own vehicle measured by the acceleration sensor only when the difference is below a prescribed value (S120).

    Abstract: PROBLEM TO BE SOLVED: To accurately estimate a vehicle body speed when in cruise control at a low speed in vehicle control.
    SOLUTION: This vehicle control device controls the driving force and braking force to be given to a vehicle so that the vehicle body speed is maintained at a target speed. The device includes specifying means (41FR, 41FL, 41RR, 41RL) to specify the wheel speed of a plurality of wheels provided to the vehicle, respectively, and a computing means (51) to compute a wheel speed effective speed concerning each wheel speed based on the specified wheel speed. The device also includes a determination means (51) to determine whether or not the wheel speed effective speed (VWV) computed for each wheel is below a predetermined speed threshold (KV) lower than a target vehicle speed, and an estimation means (51) to estimate the vehicle body speed of the vehicle based on the wheel speed determined to be an effective wheel speed by the determination means.

    Abstract: PROBLEM TO BE SOLVED: To provide a device and a method of controlling the travel of a vehicle capable of enhancing the follow-up capability to a set target deceleration by smoothly accelerating and decelerating the vehicle according to the traveling state of the vehicle. SOLUTION: The target acceleration of the vehicle is set (step ST1). A reference limit value A is acquired based on the set target acceleration TG (step ST2). The actual acceleration of the vehicle is acquired (step ST3). A limit value magnification K is so calculated that the larger the difference between the set target acceleration TG and the detected actual acceleration RG is, the larger the limit value S limiting the change of the target acceleration is (step ST4). A limit value S is calculated (step ST5). The target acceleration TG set based on the set limit value S is limited (step ST6). A limited drive force is calculated based on the limited target acceleration SG (step ST7). The calculated limited drive force is generated by a selected limited drive force generating means (step ST8). COPYRIGHT: (C)2008,JPO&INPIT
