Abstract: PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device which diagnoses the presence or absence of abnormalities of an idle stop system.SOLUTION: The abnormality diagnostic device of the idle stop system is provided with an automatic stop-and-start control means which automatically stops and automatically restarts an engine. The automatic stop-and-start control means has a stop means at travelling which automatically stops a vehicle during travelling on condition that the vehicle speed is lower than or equal to a predetermined speed when a request for automatic stop is made during vehicle travelling and a restart means at travelling which drives a starter motor and performs restart without wait for the vehicle speed to become zero when a request for automatic restart is made during vehicle travelling. Then at initial request for automatic stop (S10:YES), automatic stop by the stop means at travelling is prohibited, and the automatic stop of the vehicle is performed on condition that the vehicle speed is zero (S20). At the subsequent initial request for automatic restart (S30:YES), the presence or absence of abnormalities in the idle stop system is diagnosed (S40).

Abstract: PROBLEM TO BE SOLVED: To solve such problems that the driving of a brake actuator 20 or an electric power steering system 30 suffers from a trouble when automatic startup processing is performed by operating a starter 38 after automatic stop processing of an engine 10. SOLUTION: When the operation of a brake is performed, the minimum voltage of an auxiliary battery 38 associated with the startup of the starter 38 is predicted when it is presumed that automatic stop processing and the subsequent restart processing have been performed. The variable setting of the threshold value speed used for performing automatic stop processing is made in accordance with the predicted minimum voltage. To be more specific, the lower the minimum voltage is, the more it reduces the threshold value. Automatic stop processing is performed by making the travelling speed of a vehicle smaller than or equal to the threshold value speed. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an automatic stop/start device for an internal combustion engine capable of accurately performing execution permission determination of an automatic stop by simple processing.
SOLUTION: A detecting means is provided for detecting the electric current and the voltage flowing to an on-vehicle battery. When a current detection value and a voltage detection value detected by the detecting means just before automatic stop processing is in the low current side and the high voltage side with respect to a determination line L set in accordance with the current and the voltage flowing to the battery, execution of the automatic stop is permitted. Thus, execution permission determination of the automatic stop can be performed by the simple processing compared to processing for estimating SOC (state of charge).

Abstract: PROBLEM TO BE SOLVED: To accurately determine engine starting performance by considering changes on engine temperature and a battery state in future. SOLUTION: An engine starting performance determination section 70 calculates an intersection point (an intersection point of V-N) on a coordinate for an output voltage (V) of a battery 30 at the time of starting and the number of rotation (N) of an engine 10 at each starting of the engine 10 and stores data of the V-N intersection points and data of an engine temperature detected by an engine temperature sensor 14 as data set at the time of engine starting.

Then, the starting performance of the engine 10 at the afterward time is determined on the basis of the forecast V-N intersection points. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To highly accurately calculate the internal resistance of a secondary cell for a vehicle, without having to use a current sensor of a large current range.
SOLUTION: A current value Ibe and a voltage value Vbe, immediately prior to large current discharge, are stored as a precharging coordinate point (S303). During this large-current discharge, a large number of voltage-current pairs of currents Ib and voltages Vb only for the periods of currents within a predetermined current range are stored (S304), and from the stored large number of voltage-current pairs a regression curve (regression line will do, as well) is found by a hithertofore-known method (S305). By substituting a predetermined discharge current value Ip, which is larger than the current values in a detectable current range of a current sensor, in the regression curve, a voltage value Vp is calculated, and the current value Ip obtained and makes the voltage value Vp a maximum discharge coordinate point (S306). Next, the internal resistance value Rin is calculated from the current value Ibe found, the voltage value Vbe, the current value Ip and the voltage value Vp (S307). By doing so, the internal resistance of the secondary cell for the vehicle can be detected with accuracy that is significantly higher than that of the conventional types.

Abstract: PROBLEM TO BE SOLVED: To prevent a decline in the accuracy of deciding an SOC (a charging rate) caused by variations in polarization state.
SOLUTION: The amount of polarization of a battery is stabilized (s202 to s205). After stability in the amount of polarization has been confirmed (s205), the generation of electricity is stopped, and the current of the battery is sufficiently changed to collect a necessary number of voltage/current data pairs of the battery (s205, s206). Using these data pairs, the SOC (the charging rate) is estimated (s208, s209).

Abstract: PROBLEM TO BE SOLVED: To hold a conductive plate member for an antenna element, while preventing deterioration of the characteristic of a circular polarization antenna. SOLUTION: A ground plate 10 and a conductive plate member 20 for the antenna element are oppositely disposed apart from each other. By means of sliding elements 21a, 21b mounted on the conductive plate member 20 for the antenna element, there are formed orthogonal circular polarization routes R1, R2 each having a different length. In a state of penetrating the conductive plate member 20 for the antenna element, the ground plate 10 is fixed with the conductive plate member 20 for the antenna element by means of screws. In positions apart from the circular polarization routes R1, R2, through-holes 22b-22e for passing the screws through in the conductive plate member 20 are formed at positions other than the cross point N of the orthogonal circular polarization routes.

Abstract: PROBLEM TO BE SOLVED: To improve the characteristics of a substrate type balanced-to- unbalanced converter. SOLUTION: A pair of line patterns 21 and 22 are formed on both planes 1a and 1b of a substrate 1 and they are made into a converting part T, which performs conversion between a balanced signal and an unbalanced signal. Insertion loss is reduced and also the phase difference between balanced outputs which is outputted to balanced terminals 25 and 26 is suppressed by making one line pattern 22 three to eight times as wide as the other line pattern 21.
