The invention discloses a power supply system and a control method thereof, an automatic driving vehicle and a power supply management device, relates to the technical field of power supplies, and canbe applied to the field of automatic driving, especially the field of autonomous parking. The power supply system comprises a high-voltage power supply module, a low-voltage power utilization module,a first power supply converter, a second power supply converter, a low-voltage power supply distribution module and a power supply management module. The first power supply converter and the second power supply converter are both connected to the high-voltage power supply module so as to convert high-voltage electricity of the high-voltage power supply module into low-voltage electricity; the low-voltage power supply distribution module comprises a first relay and a second relay, the first relay is connected between the first power supply converter and the low-voltage power utilization module, and the second relay is connected between the second power supply converter and the low-voltage power utilization module; and the power supply management module is used for controlling the on-off ofthe second power supply converter and controlling the on-off of the first relay and/or the second relay. The technology can provide a redundant power supply for the power supply system, realizes redundant control of the power supply, and improves the reliability and safety of the power supply system.
