Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of this specification clearer, the technical solution of this specification will be clearly and completely described below in conjunction with specific embodiments of this specification and corresponding drawings. Apparently, the described embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this specification.

[0048] The power supply system on the unmanned equipment is usually divided into a high-voltage power supply system and a low-voltage power supply system. The high-voltage power supply system can provide power for the unmanned equipment so that the unmanned equipment can drive normally. Since the electronic control unit (Electronic Control Unit, ECU) where the unmanned driving system is ins...

Abstract

The invention discloses a vehicle-mounted battery state monitoring system, method and device, and the method comprises the steps: monitoring the charging state of a vehicle-mounted battery through monitoring equipment which is electrically connected with the vehicle-mounted battery on unmanned equipment and a processor, and enabling the processor to carry out the monitoring of the state of the vehicle-mounted battery according to the monitored charging state of the vehicle-mounted battery; and judging whether the vehicle-mounted battery of the current unmanned equipment has a short-circuit risk or not, if the current vehicle-mounted battery has the short-circuit risk, giving out an early warning, and controlling the unmanned equipment according to a preset degradation control strategy. According to the method, equipment for monitoring the state of the vehicle-mounted battery is added between the vehicle-mounted battery and the processor on the unmanned equipment, and the unmanned equipment is controlled by adopting a degradation control strategy when the short circuit risk of the vehicle-mounted battery is determined, so that emergency braking of the unmanned equipment caused by the short circuit of the vehicle-mounted battery is avoided.

Description

technical field [0001] This specification relates to the field of unmanned driving technology, in particular to a vehicle battery state monitoring system, method and device. Background technique [0002] With the development of science and technology, unmanned driving is also on the rise, and unmanned vehicles, drones and other unmanned equipment are gradually applied to various industries. In order to prevent the failure of the processor used to control the unmanned equipment and cause the unmanned vehicle to lose control, the unmanned equipment is usually equipped with a backup processor with the same function as the processor. [0003] The power supply system on unmanned equipment is divided into high-voltage power supply system and low-voltage power supply system, such as figure 1 As shown, in the actual driving process of the unmanned equipment, usually the high-voltage power supply system on the unmanned equipment outputs low voltage through the transformer to supply ...
