Standby power, also called vampire power, vampire draw, phantom load, ghost load or leaking electricity ("phantom load" and "leaking electricity" are defined technical terms with other meanings, adopted for this different purpose), refers to the way electric power is consumed by electronic and electrical appliances while they are switched off (but are designed to draw some power) or in standby mode. This only occurs because some devices claimed to be "switched off" on the electronic interface, but are in a different state from switching off at the plug, or disconnecting from the power point, which can solve the problem of standby power completely. In fact, switching off at the power point is effective enough, there is no need to disconnect all devices from the power point. Some such devices offer remote controls and digital clock features to the user, while other devices, such as power adapters for disconnected electronic devices, consume power without offering any features (sometimes called no-load power). All of the above examples, such as the remote control, digital clock functions and—in the case of adapters, no-load power—are switched off just by switching off at the power point. However, for some devices with built-in internal battery, such as a phone, the standby functions can be stopped by removing the battery instead.

The embodiment of the invention discloses a power supply control device and method applied to an automobile braking system, and belongs to the field of automobile control. The power supply control device applied to the automobile braking system comprises a plurality of power supply circuits, the input ends of the power supply circuits are used for being connected with a power source, and the output ends of the power supply circuits are used for being connected with loads; a power supply switch is arranged on the power supply circuit, the power supply switch divides the power supply circuit into a plurality of stages, and electric signal detection units are arranged on different stages; and the input end of the backup power supply switch is used for being connected with a backup power supply, and the output end of the backup power supply switch is connected with each power supply circuit and is connected between the power supply switch and the output end of the power supply circuit. According to the invention, accurate management and control of faults are realized, power supply abnormity of the load due to the faults is avoided, load damage and fault diffusion risks are prevented, the overall function of an automobile braking system is not easy to degrade, and the continuous requirement of an intelligent driving system on'lossless safety 'is met.
