Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for further correcting output of acceleration sensors for vehicles and capable of accurately correcting the drift errors of the acceleration sensors.
SOLUTION: On the basis of output of the acceleration sensors 90 and 92, when a means (166) for determining a linear cruse over a flat road at a constant speed has determined that a vehicle is cruising linearly over a flat road at a constant speed, the output of the acceleration sensors 90 and 92 is corrected at an acceleration correction means 168. Acceleration values from the acceleration sensors are thus advantageously and corrected accurately, in comparison with a conventional correction device which considers that a vehicle is linearly cruising, when the difference between right and left rotation speeds of the vehicle remains within a prescribed value and takes the output values of the acceleration sensors 90 and 92 at the time as drift errors.

Abstract: PROBLEM TO BE SOLVED: To provide an output corrector of acceleration sensor for vehicle in which drift error of acceleration sensor can be corrected more accurately. SOLUTION: When an engine output decision means 166 makes a decision that the output from an engine 10 falls within a specified range, an acceleration correcting means 168 corrects the outputs from acceleration sensors 90, 92 based on the outputs therefrom. Alternatively, outputs from the acceleration sensors 90, 92 are corrected based on the pavement inclination θ in the longitudinal direction estimated by a pavement inclination estimating means 166. Furthermore, outputs from the acceleration sensors 90, 92 are corrected based on the outputs therefrom when flat road constant speed straight traveling is determined by the means 166. Output from the acceleration sensor can be corrected accurately as compared with a conventional corrector where a decision is made that a vehicle is traveling straight if the difference between left and right rotational speeds falls with a specified range and the outputs from the acceleration sensors 90, 92 are employed as a drift error.
