Abstract

The invention discloses an automobile chassis domain control sensor architecture and dynamic state fusion calculation method, which comprises a chassis, wherein the chassis is provided with a suspension, a wheel speed sensor, a vertical acceleration sensor and a suspension displacement sensor, wheels arranged on the suspension, the wheel speed sensor, the vertical acceleration sensor and the suspension displacement sensor form a set of wheel assembly, and four sets of wheel assemblies are arranged on the chassis, namely, a left front wheel assembly, a left rear wheel assembly, a right front wheel assembly and a right rear wheel assembly. According to the invention, the wheel speed sensor, the vertical acceleration sensor, the suspension displacement sensor and the like are arranged for obtaining rotating speed parameters and vertical bounce acceleration parameters of the wheels, relative position change parameters of the wheels relative to chassis position change and the like. According to the invention, the running state of the wheels can be comprehensively acquired through the sensors, so that more comprehensive control parameters are provided for automatic control of the vehicle, and the calculation precision of the automobile dynamic state is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of automobile automation control, and more specifically, relates to a fusion calculation method of an automobile chassis domain control sensor architecture and a dynamic state. Background technique [0002] With the continuous improvement of the electronic control integration of the automobile chassis, higher requirements are put forward for the calculation accuracy and reliability of the dynamic state in the intelligent control of the automobile. [0003] However, in the prior art, the sensors installed on the car are very limited, and the more common ones include longitudinal acceleration sensors and wheel speed sensors. The type and number of sensor settings are limited, which greatly limits the improvement of the calculation accuracy of the vehicle dynamic state. Contents of the invention [0004] To sum up, how to provide a novel vehicle chassis domain control sensor architecture and dynamic ...
