Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle inertial motion data collector. Background technique [0002] The vehicle's motion data includes: the vehicle's longitudinal motion speed, lateral motion speed, motion direction, acceleration, motion trajectory, roll, pitch and other information, which are important for vehicle monitoring, control, accident identification, and assisted safe driving. significance. For example: the lateral motion speed can identify the sideslip of the vehicle and be used in vehicle control, such as electronic stability system (ESP); the acceleration can be used to identify the collision accident of the vehicle; the motion trajectory can be used to monitor the driving behavior of the driver and analyze the accident Liability (sudden lane change, emergency stop and emergency braking, etc.); roll can be used to warn of vehicle rollover; the ratio of longitudinal speed to lateral speed can be used...
