Multi-working-condition suspension previewing system based on intelligent networking and control method for multi-working-condition suspension previewing system

Abstract

The invention discloses a multi-working-condition suspension previewing system based on intelligent networking and a control method for the multi-working-condition suspension previewing system. The multi-working-condition suspension previewing system comprises a database unit, a sensor unit, an ECU, a vehicle working condition adjusting module and an expert system. Through the intelligent networking technology, the road condition in front of a vehicle can be previewed, and the vehicle is intelligently switched among a comfort working condition, a standard working condition and an energy storage working condition. Under the comfort working condition, the parameters of a suspension can be automatically changed, so that the suspension is suitable for the current road condition; and under the energy storage working condition, energy can be recycled to supply power to vehicle-mounted electrical equipment, and therefore the purposes of energy conservation, emission reduction and environment-friendly travel are achieved. Meanwhile, information sharing is achieved through the system, and the accuracy and the validity of data in a database are guaranteed. By the adoption of the system, the taking comfort and the operation stability of the vehicle can be effectively improved, the requirements for the sensing distance and the accuracy of a sensor and the performance of a vehicle-mounted computer are low, practicality is high, and the system has the important significance in development of medium-high-grade vehicles and intelligent transportation.

Description

technical field [0001] The invention belongs to the field of vehicle suspension system control optimization, in particular to the control of the multi-working condition vehicle suspension system applying the inerter technology. The invention relates to a method for actively adjusting suspension working conditions, in particular to an intelligent network-based multi-working condition suspension preview system and a control method thereof. Background technique [0002] The road condition detection technology can detect the condition of the road, and then realize the analysis of the road surface spectrum, which has a non-negligible effect on the ride comfort and even the driving safety of the vehicle. The current road condition detection technology mainly includes real-time acquisition method and preview analysis method. Among them, the real-time acquisition method is to use sensors to detect the road conditions in front of the vehicle, and send the data to the on-board comput...
