The invention discloses a control method of a rear wheel drive-by-wire electro-hydraulic steering system. The method is characterized in that a mode of an automobile is divided into a four-wheel-drivesame-direction mode, a four-wheel-drive different-direction mode, a two-wheel-drive self-locking mode, a manual selection mode and a fault protection mode according to a front wheel turning angle signal and an automobile speed signal of automobile driving. Steering stability is guaranteed under a high-speed small-turning-angle working condition, steering maneuverability is guaranteed under a low-speed large-turning-angle working condition, meanwhile, driving flexibility is improved through the manual selection mode, and vehicle safety is improved through the fault protection mode.
本发明公开了一种后轮线控电液转向系统的控制方法,其特征在于,根据车辆行驶的前轮转角信号和车速信号将汽车分为四驱同向模式、四驱异向模式、两驱自锁模式、手动选择模式和故障保护模式,在高速小转角工况下保证转向稳定性,在低速大转角工况时保证转向机动性,同时手动选择模式提高驾驶灵活性,而故障保护模式提高车辆安全性。
