Abstract

The invention discloses an automobile wire control dynamic control system for automatic driving and intelligent auxiliary driving and a control method of the automobile wire control dynamic control system. According to the automobile wire control dynamic control system, a driver operation signal, a vehicle state signal and a brake instruction are obtained under various driving modes such as manual driving, automatic driving, intelligent auxiliary driving and the like of a driver, then through the judgment, the operation and the decision of the braking conditions, the braking modes and the braking state judgment module, the target braking force instructions of the wheels are obtained under each braking state and the braking mode, and finally the target braking force instructions of the wheels are sent to a braking execution mechanism controller through a vehicle-mounted bus. The automobile wire control dynamic control system is high in universality and flexibility, not only can be used for a traditional automobile, but also can be used for a new energy automobile, not only can be used for an electro-hydraulic braking system, but also can be used for an electronic mechanical braking system.

Description
