The invention provides an emergency steering test method, a power-assisted steering control system and a vehicle. The power-assisted steering control system comprises a steering motor high-voltage winding, a steering motor low-voltage winding, a steering oil pump high-voltage controller and an emergency steering low-voltage controller, and the power-assisted steering control system has a high-voltage steering working mode and an emergency steering working mode which can be switched. The method comprises the steps that when an emergency steering test needs to be conducted on a vehicle, a VCU forced low-pressure steering enabling switch is controlled to be turned on; and when a key ON gear signal is received and the vehicle speed is greater than a preset vehicle speed threshold value, the connection between the steering oil pump high-voltage controller and the steering motor high-voltage winding is controlled to be cut off, the emergency steering low-voltage controller is controlled to be connected with the steering motor low-voltage winding, and an emergency steering working mode is switched to perform an emergency steering test on the vehicle. According to the invention, emergency steering testing can be carried out on the vehicle in advance according to needs.
本申请提供一种应急转向测试方法、助力转向控制系统及车辆。该助力转向控制系统包括转向电机高压绕组、转向电机低压绕组、转向油泵高压控制器及应急转向低压控制器,助力转向控制系统具有可切换的高压转向工作模式和应急转向工作模式。该方法包括:当需要对车辆进行应急转向测试时,控制VCU强制低压转向使能开关开启;当接收到钥匙ON档信号并在车速大于预定车速阈值时,控制切断转向油泵高压控制器与转向电机高压绕组的连接,并控制应急转向低压控制器与转向电机低压绕组连接,切换进入应急转向工作模式以对车辆进行应急转向测试。本申请能够根据需要来提前对车辆进行应急转向测试。
