Abstract

The invention discloses a wire-controlled steering system for a new energy passenger car, and belongs to the technical field of new energy buses. The wire-controlled steering system comprises a steering input system, a steering control system, a steering execution system, a safety redundancy system and a sensor; the steering control system is correspondingly connected with the steering input system, the steering control system, the safety redundancy system and the sensor, and a CPU in the steering control system is correspondingly connected with a steering operation end in a steering input system and a steering mode switcher in the safety redundancy system through a wire; a steering motor in the steering execution system is connected with a steering motor controller in the steering controlsystem; the sensor is connected with a sensor data interface in the transformation steering control system through a wire; and the steering operation end in the steering input system is connected with wheels in the steering execution system through a mechanical steering controller in the safety redundancy system. According to the wire-controlled steering system, the problem that a current new energy intelligent passenger car lacks a mature steering control system to guarantee the normal driving safety is solved.

Description

technical field [0001] The invention relates to the technical field of new energy buses, in particular to a steering-by-wire system for new energy buses. Background technique [0002] New energy smart vehicles are considered to be able to effectively solve problems such as urban road traffic congestion, frequent traffic accidents, and air pollution, and their development has attracted worldwide attention. Intelligent driving is the key technology to realize "smart car" and "smart transportation". Steering by wire is a key technology necessary for intelligent driving vehicles to achieve path tracking and obstacle avoidance. Its performance directly affects active safety and driving experience. The specific development of the steering control system for energy smart vehicles is still a sufficiently mature technology to meet complex control requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steer-by-w...
