An intelligent electric vehicle ACC/ESC integrated control system and method thereof

Abstract

An intelligent electric vehicle ACC / ESC integrated control system and method thereof are provided with an information acquisition module, a monitor, a decision controller and a coordinated actuator. The information acquisition module comprises a vehicle-vehicle communication module, a radar and a vehicle sensor module; the monitor comprises a state parameter estimation module, a prediction moduleand a driving state judgment module. The vehicle-vehicle communication module, a radar module and a vehicle-mounted sensor module are connected with a state parameter estimation module, a prediction module and a running state judgment module, and an output end of the state parameter estimation module is connected with an input end of the prediction module; the decision controller includes a control mode selection module and an ACC / ESC integrated controller. An input end of the control mode selection module is connected with an output end of a prediction module and a driving state judgment module, and an output end of the control mode selection module is connected with an input end of an ACC / ESC integrated controller. The coordinating actuator includes a drive system and an active braking system.

Description

technical field [0001] The invention relates to the field of automobile auxiliary driving and active safety control, in particular to an intelligent electric vehicle ACC / ESC integrated control system and a method thereof. Background technique [0002] With the rapid development of the automobile industry, problems such as environmental pollution, traffic accidents, and road congestion are becoming more and more serious. Therefore, safety, comfort, energy saving, and intelligence are the current development directions of automobiles. Smart electric vehicles that integrate electrification and intelligent technologies have attracted widespread attention. Active safety technologies such as Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) ensure the driving safety of the vehicle to a certain extent. As a new generation of cutting-edge technology, Advanced Driver Assistance System (Advanced Driver Assistance System, ADAS) is also one of the automotive safety ...

AI Technical Summary

Problems solved by technology

However, when the vehicle adaptive cruise is in complex driving conditions, such as the ACC condition of the curve, the vehicle has longitudinal and yaw motions at the same time, and the independent longitudinal motion control system cannot guarantee the lateral stability of the vehicle.
