The invention relates to the technical field of vehicle control, in particular to a control system and method for a double-source steering oil pump of a passenger car. A whole vehicle controller is configured as follows: when a key is in an ON gear and the whole vehicle is not in a high-pressure state, after a rain and snow mode switch is continuously triggered for a set number of times within a set time period, the whole vehicle is started; a starting instruction and a low-pressure power-assisted steering oil pump detection flag bit are sent to a low-pressure power-assisted steering oil pump controller; when the vehicle is in a high-pressure state and a fault influencing the high-pressure state does not exist, a starting instruction is sent to a high-pressure power-assisted steering oil pump controller; when the vehicle is in a high-pressure state and has faults influencing high pressure, a high-pressure lowering instruction and a high-pressure power-assisted steering oil pump shutdown instruction are sent out, meanwhile, a vehicle speed value is determined, if the vehicle speed is larger than a critical speed value, a starting instruction is sent to a low-pressure power-assisted oil pump controller, and if the vehicle speed is not larger than the critical speed value, a starting instruction is sent to a low-pressure power-assisted oil pump controller; and a shutdown instruction is sent to the low-pressure power-assisted oil pump controller.

    本发明涉及车辆控制技术领域,具体为一种客车双源转向油泵的控制系统及方法,整车控制器被配置为:当钥匙处于ON档,并且整车未处于高压状态时,设定时间段内雨雪模式开关连续触发设定次数后,向低压助力转向油泵控制器发送开机指令和低压助力转向油泵检测标志位;车辆处于高压状态,并且没有影响高压状态的故障时,向高压助力转向油泵控制器发送开机指令;车辆处于高压状态,并且存在影响下高压的故障时,发出下高压指令和高压助力转向油泵关机指令,同时确定车速值,若此时车速大于临界速度值,向低压助力油泵控制器发送开机指令,若此时车速不大于临界速度值,向低压助力油泵控制器发送关机指令。
