The invention discloses a steer-by-wire system with an energy recovery function and a road feel control method thereof. According to the system, a power generation module is additionally arranged in atraditional steer-by-wire system, and the power generation module comprises a power generator, a rectifier, a super capacitor and a filtering module, and a resistance torque generated when the powergenerator works is used as a source of steer-by-wire road feel; and meanwhile, an original road feel motor is used for adjusting the road feel, good road feel can be provided for a driver, and meanwhile, energy output by steering of the driver is recycled. Besides, the mechanism capable of providing the road feel comprises the road feel motor and the generator, so that when the road feel motor breaks down, the generator can continuously provide a certain road feel for the driver, the system redundancy is improved, and meanwhile, early warning can be provided for the driver.
本发明公开了一种具有能量回收功能的线控转向系统及其路感控制方法,该系统在传统线控转向系统中添加了发电模块包括:发电机、整流器、超级电容和滤波模块,利用发电机工作时产生的阻力矩作为线控转向路感的来源,同时利用原有路感电机进行路感的调节,能够实现为驾驶员提供良好路感的同时,回收驾驶员转向输出的能量。另外,由于本发明可以提供路感的机构包括路感电机和发电机,因此当路感电机故障时,发电机还能持续为驾驶员提供一定路感,提高系统冗余性的同时还能够给驾驶员进行预警。
