Abstract

The invention discloses an active collision avoidance and fault tolerance system for a distributed driving vehicle and a working method thereof. The active collision avoidance fault tolerance system includes an environment perception module, a state parameter perception module, a collision avoidance decision planning module, a fault diagnosis module, and a drive fault tolerance requirement Decision-making module and path tracing fault-tolerant control module. The invention classifies the fault categories of the in-wheel motors, and divides the fault-tolerant requirements into power requirements, stability requirements and strong stability requirements when the fault-tolerant system is Various working conditions in the collision fault tolerance control process. The invention classifies the hub motor faults, controls different fault-tolerant demand information respectively, and performs drive anti-skid control on the hub motor under the control of the fault-tolerant system, which can effectively ensure that the hub motor fails during the active collision avoidance process of the distributed drive vehicle time dynamics and lateral stability.

Description

technical field [0001] The invention belongs to the field of vehicle active safety, and more specifically relates to a distributed drive vehicle active collision avoidance fault-tolerant system and a working method thereof. Background technique [0002] my country vigorously promotes energy conservation and ecological environment protection policies, and research on electric vehicles has become a hot spot and focus in the automotive industry. As a kind of electric vehicle, distributed drive vehicle has the advantages of independent controllability of all wheels, fast torque response, energy saving and environmental protection, which is of great significance to improve the mobility, safety, energy saving and stability of the vehicle. [0003] With the development and maturity of distributed drive vehicle technology, the safety issue is the most critical issue affecting its road use, and the development of advanced active safety systems based on distributed drive vehicles is a...
