Title:
METHOD FOR DETECTING ROLL STATE OF VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/103941
Kind Code:
A1
Abstract:
A method for detecting a roll state of a vehicle comprises: 1. collecting a sideward acceleration abh of a vehicle and an acceleration abv in a direction vertical to the ground; 2. obtaining a roll angle φ of the vehicle and a sideward acceleration ay of the vehicle relative to a geodetic coordinate system; and 3. comparing the obtained roll angle φ of the vehicle with a set roll angle range, and performing judgment, so as to obtain a roll state of the vehicle. A roll angle φ of a vehicle is directly calculated by using a biaxial acceleration sensor (3), so as to obtain roll state information of the vehicle, so that effective roll state information of the vehicle can be obtained more directly and rapidly, and technical support is provided for follow-up roll control and warning, so as to avoid an rollover accident of the vehicle.
