Wheel-loaded intelligent sensing wheel movement attitude monitoring method

Abstract

The invention discloses a movement posture monitoring method based on a wheeled intelligent sensing wheel, which comprises the following steps: an equatorial plane of a hub of each wheel of a vehicle is provided with a top-free microinertia measuring unit, sensing signals are conditioned, digitized and calculated by a posture algorithm way, and main movement posture parameters of the wheels are obtained; the main movement posture parameters of the monitored wheels comprise tangential acceleration, sideward acceleration, acceleration centripetal, advance speed, side velocity, angular acceleration, camber angles, slip angles, heading angles, and the like; after the parameters are inosculated and analyzed through a plurality of sending data, the movement safety condition of the wheels such as the unbalanced degree, looseness, fly off, slippage, and the like of wheels can be monitored and actively estimated, thereby being favorable for preventing and reducing the occurrence of traffic accidents.

Description

technical field [0001] The invention relates to a method and a device for monitoring the safe running state of a motor vehicle, in particular to a monitoring method for monitoring the instantaneous state of the wheel movement attitude of the motor vehicle during driving.

Problems solved by technology

[0004] At present, the monitoring of the wheel motion only involves the acquisition of the local acceleration curve of the tire, without in-depth analysis of the wheel motion attitude, so it is impossible to analyze the influence of the wheel motion attitude parameters on the body motion attitude parameters, dynamic load parameters, and braking performance parameters

Therefore, it is necessary to monitor and predict the motion attitude of motor vehicle tires in order to fully reflect the safe state of motor vehicle operation; impact, so that the acceleration curve produces periodic changes, and the measured acceleration curve is distorted. Second, the actual acceleration state of the wheel cannot be expressed; at the same time, due to the untrue measurement of the acceleration, there is no and no way to further measure the three-dimensional acceleration and attitude angle of the wheel. analysis and calculation

Therefore, the monitoring of the motion posture of the wheels is not comprehensive, and there is no and cannot establish the relationship between the motion posture of the wheels and the motion posture of the vehicle body
