摘要： PROBLEM TO BE SOLVED: To provide a controller for vehicle, securely performing memory check without having bad influence on control. SOLUTION: A storage area of a flash memory ROM 27 is split in advance into a plurality of split areas based on execution procedure of a plurality of subprograms constituting a control program. Followed by the execution procedure of a plurality of the subprograms, memory check is successively performed on one split area to store the subprogram to be run next out of a plurality of the split areas. When the memory is determined as normal in the memory check, the subprogram stored in the split area is run. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an intake pressure estimating device for accurately estimating intake pressure (bottom pressure)near at piston bottom dead center in an intake stroke.
SOLUTION: The bottom pressure PB18' being the intake pressure near at the bottom dead center is estimated based on a detection value PB16 of bottom just before pressure being intake pressure just before the bottom before the bottom dead cente (S30: a bottom pressure estimating means). A deviation DPB1 between a last time estimate value PB18' being the bottom pressure estimated in the intake stroke of the last time and a last time detection value PB18 being actual bottom pressure acquired in the intake stroke of the last time, is calculated as an estimation error (S31:an estimation error calculating means). This time estimate value PB18' being the bottom pressure estimated in the intake stroke of this time is corrected based on the estimation error DPB1 by the last time estimate value PB18' and the last time detection value PB18 (S33:a correction means), and an estimate value of the bottom pressure provided by this correction is set as the final estimate bottom pressure PB18.

SOLUTION: The bottom pressure PB18' being the intake pressure near at the bottom dead center is estimated based on a detection value PB16 of bottom just before pressure being intake pressure just before the bottom before the bottom dead center (S30:a bottom pressure estimating means).

摘要： PROBLEM TO BE SOLVED: To provide a data rewriting method of a memory for storing data as latest as possible even when data are destroyed. SOLUTION: The rewrite area of a flash memory 13 is divided into a plurality of regions, and data rewrite is successively performed to a plurality of divided areas A to D, and the rewrite areas are changed at every rewrite. Data are stored in the plurality of divided areas A to D, and the past data are kept in the other areas while rewriting the data in the area most recently selected. Therefore, even when the data are destroyed due to power interruption during the rewrite of the newest data, it is possible to hold the past data in the area different from the area being rewritten.

摘要： PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine which can perform an ignition operation at an optimal ignition timing.
SOLUTION: The ignition device for an internal combustion engine includes a crank angle sensor 2 and a control means 1. The crank angle sensor 2 outputs at least three crank angle signals during one rotation of a crankshaft. The control means 1 decides deceleration of the crankshaft from those crank angle signals and also decides the time of outputting an ignition signal to an ignition coil from the deceleration. The ignition device for an internal combustion engine can perform an ignition operation at an optimal timing even when the rotating fluctuation in one combustion cycle is relatively large.

摘要： A rotor of a crankshaft has protrusions. A timing sensor produces a rotation leading signal and a rotation trailing signal. A control unit measures a previous signal production interval and a present signal production interval based on the rotation signals, and determines that the rotor is in the forward rotation if an inequality of Tn/Tn-1>=K holds alternately but consecutively by four times on the side of the rotation trailing signal. As a result, at the time of manufacturing the rotor, the degree of freedom of design in the positional relations of the protrusions can be enhanced to control the ignition timing precisely and stably.
