摘要： To accurately identify a vehicle state. An apparatus identifies a vehicle state and includes a controller connected with an angular velocity sensor and an acceleration sensor, where the controller acquires acceleration per unit time along a vehicle's longitudinal direction axis from the acceleration sensor, determines acceleration variation over a certain period of time, acquires angular velocity per unit time around vehicle's roll axis from the angular velocity sensor, determines the angular velocity variation during the certain period of time, and identifies the vehicle as a first state when the acceleration variation is greater than a first threshold value and the angular velocity variation is greater than a second threshold value, and identifies the vehicle as a second state when the acceleration variation is less than the first threshold value and the angular velocity variation is less than the second threshold value, and outputs the identified result.
