|1. (WO2018179764) OVERTURN DETECTION DEVICE FOR MOTORCYCLE|
|Title:||OVERTURN DETECTION DEVICE FOR MOTORCYCLE|
An overturn detection device (4) for a motorcycle (1) detects whether the motorcycle (1) has overturned, on the basis of an inclination angle (θi) of the vehicle body. The overturn detection device (4) is provided with an acceleration sensor that has two detection axes (10A, 10B) which intersect at an intersection angle (θc) which forms an acute angle with the vertical direction (Y) when the vehicle body is in a non-inclined upright state, and the acceleration sensor detects the vehicle-body acceleration speed (Acc) used for calculating the inclination angle of the vehicle body, such detection carried out along the detection axes (10A, 10B) in detection directions which are downward to the left and right of a vehicle width direction (Dw).
