The invention relates to a redundant power supply system of a commercial vehicle and a control method, and belongs to the technical field of vehicle power supply, the redundant power supply system comprises an emergency power switch, a main power supply and distribution loop, a redundant power supply and distribution loop and a generator, the main power supply and distribution loop is connected to the generator, and the redundant power supply and distribution loop is connected to the generator through the emergency power switch; and the redundant power supply and distribution loop is also connected to the main power supply and distribution loop. When any power supply and distribution loop fails, the emergency power switch can disconnect the failed power supply and distribution loop and ensure that the other power supply and distribution loop can continue to work normally, failure of the whole loop caused by single-point failure in the loop is avoided, reliability of an electronic and electrical system of the whole vehicle is improved, and the service life of the whole vehicle is prolonged. And meanwhile, the driving safety is improved. And meanwhile, the power supply and distribution loop can be diagnosed in real time through the controller network, and faults in the power supply and distribution loop can be quickly responded, so that the safety of the power supply and distribution loop and the safety level of the redundant power supply system are greatly improved.

    本发明涉及一种商用车的冗余电源系统及控制方法,属于车辆供电技术领域,包括紧急电源开关、主供配电回路、冗余供配电回路和发电机,主供配电回路连接到发电机,冗余供配电回路通过紧急电源开关连接到发电机,冗余供配电回路还连接到主供配电回路。本发明能够当任一供配电回路发生故障时,紧急电源开关能够将发生故障的供配电回路断开,并保证另一路供配电回路能够继续正常工作,避免回路中单点故障而引起整个回路的失效,提高了整车电子电气系统的可靠性,同时提高了驾驶的安全性。同时能够通过控制器网络能够实时进行供配电回路的诊断,并快速响应供配电回路中出现的故障,大大提高了供配电回路的安全性及冗余电源系统的安全等级。
