Control method of deceleration and braking actuator of automobile intelligent anti-collision system

Abstract

The invention discloses a decelerating and braking actuator for an intelligent anti-collision system of an automobile and a control method of the decelerating and braking actuator. The decelerating and braking actuator for the intelligent anti-collision system of the automobile is characterized in that the decelerating and braking actuator not only comprises an original automobile braking system, but also comprises a second braking system, the second braking system comprises a stepping motor, a cam, a piston rod and a pipeline used for circulating hydraulic oil, the stepping motor is fixedly connected with the cam which is connected with the piston rod, the stepping motor, the cam and the piston rod form an overall mechanism together, the overall mechanism can simulate the action of stepping on a pedal, and therefore the second braking system is controlled to complete the action of decelerating or braking. According to the decelerating and braking actuator for the intelligent anti-collision system of the automobile and the control method of the decelerating and braking actuator, the corresponding execution action can be made reliably in time according to the judgment of a central processing unit of the intelligent anti-collision system of the automobile, and occurrence of traffic accidents is effectively avoided; the decelerating and braking actuator can be well combined with an existing automobile structure, substantial transformation on the braking system of the automobile is not needed, the cost is reduced, installation is convenient, and popularization of the intelligent anti-collision system of the automobile is facilitated.

Description

technical field [0001] The invention relates to a control method of a deceleration and braking actuator of an automobile intelligent anti-collision system, belonging to the technical field of automobile safety equipment. Background technique [0002] In recent years, with the rapid development of the economy, more and more people are using cars as a means of transportation, and the density of cars on the road is getting higher and higher, and the problems that follow are obvious. With the rapid increase in the number of cars, traffic accidents occur frequently, resulting in an astonishing number of loss of life and property. Installing the car intelligent anti-collision system on the car can effectively avoid the occurrence of traffic accidents and reduce potential safety hazards. [0003] The car intelligent collision avoidance system includes the following three parts: [0004] (1) Radar part [0005] Detection radar is equivalent to human eyes. Its function is to cont...
