The invention provides an electric appliance system of a vehicle, an overload protection method and the vehicle. The electric appliance system comprises a driving unit, at least one load and at least one electronic switch. Wherein the driving unit is used for collecting an electrical parameter value of each load, comparing the electrical parameter value with an electrical parameter threshold value, and turning off the electronic switch under the condition that the electrical parameter value is greater than the electrical parameter threshold value; the driving unit is further used for sending the electrical parameter value to the whole vehicle control unit, so that the whole vehicle control unit determines whether to turn off the electronic switch or not according to the electrical parameter value; if a turn-off instruction sent by the whole vehicle control unit is received, the electronic switch is turned off; wherein the response time for the driving unit to turn off the electronic switch is shorter than the response time for the driving unit to turn off the electronic switch according to the turn-off instruction. According to the embodiment of the invention, the vehicle use safety can be improved.

    本申请提供了一种车辆的用电器系统、过载保护方法以及车辆,该用电器系统包括:驱动单元、至少一个负载、至少一个电子开关;其中:驱动单元,用于采集每一负载的电学参数值,将电学参数值与电学参数阈值进行比较,在电学参数值大于电学参数阈值的情况下,关断电子开关;驱动单元,还用于将电学参数值发送至整车控制单元,以使整车控制单元根据电学参数值确定是否关断电子开关;以及若接收到整车控制单元发送的关断指令,则关断电子开关;其中,驱动单元关断电子开关的响应时间小于驱动单元根据关断指令关断电子开关的响应时间。本申请实施例能够提升用车安全性。
