摘　　要：综述了轿车动力转向技术的发展,包括液压动力转向、电控液压动力转向、电动助力转向和下一代线控转向系统。分析了各转向系统的发展动因、结构、工作原理、助力特性及特点。探讨了轿车动力转向系统的发展趋势,指出电动助力转向将来动力转向技术的必然发展趋势,线控转向是未来转向系统的发展趋势。The technology and development of power steering in modern cars, including hydraulic power steering （HPS）, electrical hydraulic power steering （EHPS）, electric power steering （EPS） were explicated. The background of development, structure, working principle, assist characteristic and traits of all the power steering were described in detail, the conflicts existing in steering system, such as the conflict between maneuverability and sensitivity and the conflict between maneuverability and road feel were mentioned. As a renovating steering system, steer^by wire （SBW） was also explicated. There is no mechanical connection between steering handle wheel and steering wheel in steering by wire system, which brings many virtues to steering by wire. The development tendency of power steering was also discussed. The idea was put forward that the electric power steering is the power steering of the future, and the steering by wire is the steering system of the future.
