Abstract

The invention discloses a redundant electric assisting steering system of an automobile driving vehicle and a control method of the redundant electric assisting steering system. The electric assistingsteering system comprises a first torque coupler, a second torque coupler, a first assisting system, a second assisting system, a main controller and an alarming device. A steering wheel is connectedwith the first torque coupler through a first intermediate shaft, after being connected in parallel, the first assisting system and the second assisting system are connected with the second torque coupler through output shafts, the second torque coupler is connected with the first torque coupler through a second intermediate shaft, and the first torque coupler is connected with a steering devicethrough a third intermediate shaft. The control method includes the two portions of a control method in an active steering manner and a control method in an assisting steering manner. The redundant electric assisting steering system of the automobile driving vehicle and the control method of the redundant electric assisting steering system have the beneficial effects that sufficient time can be reserved for a driver to take over the steering wheel, the driver is prompted through the alarming device, and the safety of a steering system is effectively guaranteed.

Description

technical field [0001] The invention relates to a steering system and a control method thereof, in particular to a redundant electric power steering system of an automatic driving vehicle and a control method thereof. Background technique [0002] At present, according to relevant classification standards, intelligent assisted driving is divided into five levels, from low to high, respectively L1-L5. In recent years, with the development of autonomous driving technology, many car companies at home and abroad are actively promoting plans to transition from L2 autonomous driving to L3 autonomous driving. Among them, the brand-new Audi A8 launched in 2018 claims to have realized the L3 level autonomous driving technology stipulated by the Society of Automotive Engineers (SAE), while Japanese and Korean manufacturers Hyundai, Honda and Toyota plan to mass-produce the L3 system in 2020. In addition, , In July 2019, Mercedes-Benz and BMW also cooperated in the field of autonomous...
