New energy vehicle regional operation risk assessment and early warning system integrated with vehicle safety

Abstract

The invention discloses a new energy vehicle regional operation risk assessment and early warning system integrated with a whole vehicle safety state, which considers the characteristics that a new energy vehicle has various whole vehicle safety risks such as battery thermal runaway and power loss. The whole vehicle safety states of the vehicle and other vehicles in the domain and the weather state information in the domain are fused into an existing vehicle operation risk early warning method, and accurate evaluation and early warning of the operation risk of the new energy vehicle under the complex road traffic condition can be achieved. Driving data collected by a vehicle-mounted sensor of each vehicle in real time are processed and analyzed to complete sensing of the safety state of the whole vehicle, and the thermal runaway risk state and the power loss risk state of a vehicle battery are output; safe state extraction, motion state sensing and intra-domain weather state sensing of the vehicle and other vehicles in the domain are realized; and risk assessment and early warning is carried out on the whole-process real-time operation of the new energy vehicle based on the operation risk early warning model and strategy by fusing the safety state and the motion state of the vehicle and other vehicles in the domain and the weather state in the domain.

Description

technical field [0001] The invention belongs to the field of new energy vehicle operation safety, and more specifically relates to a new energy vehicle regional operation risk assessment and early warning system that integrates the vehicle safety status. Background technique [0002] The unique power battery, drive motor, electronic control system and other related systems and components of new energy vehicles make them have safety risks such as battery thermal runaway and power loss during operation. If a new energy vehicle encounters battery thermal runaway and power loss during operation, it may cause a collision between the own vehicle and adjacent vehicles in the area, or even further cause thermal runaway of the power battery of other vehicles in the area and vehicle fire after the collision. Therefore, under the complex operating conditions of urban traffic structure and traffic environment, the driving risk models of new energy vehicles are also diverse and complex. ...

If a new energy vehicle encounters battery thermal runaway and power loss during operation, it may cause a collision between the own vehicle and adjacent vehicles in the area, or even further cause thermal runaway of the power battery of other vehicles in the area and vehicle fire after the collision

Therefore, under the complex operating conditions of the urban traffic structure and traffic environment, the driving risk models of new energy vehicles are also diverse and complex.

At present, the new energy vehicle operation risk warning method based on the Internet of Vehicles technology does not consider its own particular vehicle safety risk
