Abstract

PURPOSE:To accurately detect whether a car is under a steady revolving movement or not by comparing the estimate of a lateral acceleration estimated from the detected value of a yaw rate, with the detected value of the lateral acceleration. CONSTITUTION:An estimate means 104 estimates a lateral acceleration which is considered to be generated when a yaw rate is generated, based on the yaw rate of a car detected by a yaw rate sensor 101. A judging means 105 judges whether a deviation between lateral accelerations detected by two lateral acceleration sensors 102, 103 which are placed with a certain distance apart from each other in the longitudinal direction of a car, is below a certain value or not. A judging means 106 judges whether a deviation between the estimate of the lateral acceleration and at least one of the detected values of the lateral accelerations is below a certain value or not. And, a detecting means 107 detects whether a car is in a condition of steady revolving movement or not, based on the two judging means 105, 106.
