Abstract

The invention relates to an automatically adjusted electric vehicle staged automatic emergency braking control system. The automatically adjusted electric vehicle staged automatic emergency braking control system comprises vehicle-mounted distance measuring and speed measuring sensor equipment, a staged pre-warning control system, a safety distance calculation model, a vehicle reverse longitudinaldynamic calculation model, a hydraulic braking force and regenerative braking force distribution and calculation module, a hydraulic braking system reverse model, an ESC and Booster active pressurizing hydraulic pressure distribution module and a pavement information estimation module; potential safety hazards such as rear-end collision of a rear vehicle caused by great sudden deceleration of a vehicle are reduced while the comfort during triggering an AEB system is improved; by estimating information, such as gradients and adhesion coefficients, of a current running road and a front road ofthe vehicle and controlling online adjusting of parameters, the adapting degree of the AEB system to different pavement statuses is enhanced, the braking energy is sufficiently recycled, the endurancemileage is increased, and the advantages of a vehicle body stability control system ESC and an electronic mechanical braking booster in active pressurizing are sufficiently developed.

Description

technical field

[0001] The invention relates to an automatic emergency braking control system for an electric vehicle, in particular to an automatically adjusted hierarchical automatic emergency braking control system for an electric vehicle. Background technique

[0002] In recent years, with the continuous development of global automobile technology, the number of automobiles has continued to increase, and vehicle traffic accidents have also increased. In order to reduce the number of road traffic accidents, various automotive active safety technologies and passive safety technologies have been developed rapidly. As an important automotive active safety technology, the Automatic Emergency Brake System (AEB, hereinafter referred to as AEB) can effectively avoid a large number of traffic accidents, and has gradually become a standard configuration of vehicles.

[0003] The AEB system is mainly composed of three parts: information collection, control system and actuator. In...
