Problems solved by technology

For unmanned vehicles, unmanned logistics vehicles, etc., a single steering assembly is difficult to guarantee their driving safety. Most of the existing vehicles equipped with advanced driver assistance systems use an electronic hydraulic power steering structure, which cannot achieve steering redundancy.
There is no report in the prior art that can have a dual-purpose steering system for autonomous steering and power assistance, so it is necessary to develop a dual-purpose steering system for autonomous steering and power assistance that is suitable for vehicles such as advanced driver assistance systems (ADAS) and automatic driving systems (ADS). redundant steering system

Abstract

The invention discloses an autonomous steering and power-assisted dual-purpose redundant steering system and a control method thereof. The steering system comprises a steering wheel (8), a steering column (6), a column type electric power-assisted steering device (7) installed on the steering column (6), a steering gear (2), a tie rod (1) and a power-assisted steering device installed on the steering gear (2). The rack type electric power steering device (3) comprises a power steering device shell, a power steering motor (301), a controller (305), a power steering transmission mechanism and a power steering gear shaft (310). And the power-assisted steering gear shaft (310) is in transmission fit with the steering gear rack (202). By means of the control method, four working modes of conventional power-assisted steering, redundant power-assisted steering, conventional autonomous steering and redundant autonomous steering can be achieved. The two independent and redundant steering devices are adopted, the occupied space is small, and more reliable steering performance and safety are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to a redundant steering system with dual functions of autonomous steering and power assist and a control method thereof. Background technique [0002] Electric Power Steering (EPS) technology is a new technology in the field of automobile steering in the past ten years, and has achieved considerable development abroad. EPS is also a research hotspot in the domestic steering system industry. Based on the EPS platform, the steer-by-wire system can be extended and developed. There is no coherent and direct mechanical connection between the steering wheel and the steering transmission mechanism. Power steering can be provided through the steering wheel angle signal and torque signal, that is, the relevant components are realized through the electrical signal route. motion control. EPS is a safety component of a car, and its performance is directly related to the safety and ...
