Abstract

The invention provides an automobile rollover prevention control system based on an electric power steering device, which belongs to the technical field of automobiles and aims to solve the problem that the automobile running safety cannot be effectively protected by the traditional automobile rollover prevention control system. The automobile rollover prevention control system based on the electric power steering device comprises an electronic control unit, a motor, a torque steering sensor and a vertical force detector which are respectively connected with the electronic control unit and a rotate speed detector which is used for detecting the rotate speed of the steering wheel, wherein the vertical force detector is used for detecting a vertical force borne by automobile wheels and sending the vertical force to the electronic control unit; when the vertical force borne by the wheels at one side of an automobile is less than a set value, the electronic control unit judges that the automobile has the rollover trend and sends a control signal to control a motor to generate a reverse moment so as to reduce the rotate speed of the steering wheel. The automobile rollover prevention control system based on the electric power steering device has the advantage that the rollover condition of the automobile is caused by overhigh rotate speed and overlarge rotor angle of the steering wheel can be effectively avoided.

Description

technical field

[0001] The invention belongs to the technical field of automobiles, and relates to an automobile anti-rollover control system, in particular to an automobile anti-rollover control system based on an electric power steering device (EPS). Background technique

[0002] With the continuous development of the automobile industry, the number of automobiles is also increasing. As the most used means of transportation, the increase of automobiles not only brings convenience to people's travel, but also brings various traffic accidents that threaten people's personal safety. Among them, in order to avoid obstacles urgently when the car is running at high speed, the driver often turns the steering wheel quickly and causes the car to roll over due to centrifugal force, thus causing more serious traffic accidents than collision with obstacles.

[0003] For this reason, people have designed a kind of automobile anti-rollover system based on ABS system, and have applied f...
