摘要： A straight running state is accurately determined using only wheel speed data in any running state. Based upon right and left wheel speed values calculated by a wheel speed calculating mechanism (13) from detection values of right and left wheel speed sensors (11, 12), a wheel speed ratio calculating mechanism (21), a distance calculating mechanism (31), and a distance ratio calculating mechanism (32) respectively calculate a right and left wheel speed ratio, an actual running distance, a linear distance, and a distance ratio of the two distances at every preset checkpoint (CP). A wheel speed ratio change amount evaluating mechanism (24) extracts CPs at times where a change amount of the wheel speed ratio is relatively small as effective CPs, and a determining mechanism (43) determines an effective CP with the smallest distance ratio from among the effective CPs as in a straight running state.

摘要： A variable value (dynamic load radial deviation &bgr;) for making determination of a tire air pressure is calculated from pulse number cumulative values PFL, PFR, PRL and PRR that are cumulated for individual wheels when a predetermined condition is fulfilled. The calculated variable value is stored as a reference variable value, and a speed of a vehicle at the time when the reference variable value is calculated is stored as a reference vehicle speed associated with the reference variable value. If the value is newly calculated, it is determined whether or not a vehicle speed at that moment is within a predetermined vehicle speed range determined by the reference vehicle speed. If it is determined that the vehicle speed is within the predetermined vehicle speed range, it is determined, based on a difference between the newly calculated variable value and the reference variable value associated with the reference vehicle speed, whether or not the tire air pressure is normal. Thus, even if the vehicle is fitted with one or more tires that depend greatly on vehicle speed, the possibility of erroneously determining that a tire air pressure is not normal can be eliminated.

摘要： An image processing apparatus includes a recorder. A recorder records repeatedly-fetched object scene images as a moving image. An extractor extracts one portion of the object scene images recorded by the recorder, in parallel with the recording process of the recorder. An evacuator alternatively evacuates a predetermined number, which is an upper limit, of the object scene images extracted by the extractor. An allocator allocates the object scene images evacuated by the evacuator at a time point at which the recording process of the recorder is ended, to the moving image recorded by the recorder. A controller starts up the evacuator at a frequency that is decreased according to an increase in an amount of moving images recorded by the recorder.

摘要： In a vehicle control device, a brake feedback control unit calculates a brake feedback torque Tfb-BK using a PID control model when a current state is a brake feedback use state. The brake feedback control unit stops the calculation of the brake feedback torque Tfb-BK when the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tfb-BK that is output at a brake limitation start timing. At a brake limitation release timing, the brake feedback control unit restarts the feedback control using the stored brake feedback torque Tfb-BK as an initial value. The brake mechanism can thereby generate a predetermined brake torque of not more than 0 [N·m] immediately after the brake limitation release timing.
