Problems solved by technology

However, because the battery protection device is manually operated, many drivers have not developed the habit of getting out of the car and turning on the battery switch, especially after the vehicle is running, the cabin temperature rises and the heat cannot be dissipated well. At the same time, if the driver If you forget to unplug the key and turn off the headlights after getting off the car, the temperature in some parts of the vehicle is prone to continuous rise, and even reaches the ignition point after a certain level, causing the vehicle to spontaneously ignite and causing huge losses
In addition, even if the vehicle does not spontaneously ignite, the long-term discharge of the battery of the vehicle will cause the battery to be insufficient, or the battery will be damaged due to over-discharge.
Therefore, in the related art, the protection of battery discharge after parking is basically based on manual operation, or protection is carried out by fuses. Once the above phenomenon occurs, the fuses will be damaged, which will cause inconvenience to users.

Abstract

The invention discloses a control method and system of a vehicle. The vehicle comprises a storage battery and a low-voltage load, and the low-voltage load is connected with the storage battery through a relay. The method comprises the following steps of S1, detecting whether a whole vehicle discharging signal is received or not; S2, if the whole vehicle discharging signal is not received, further monitoring the discharging condition of a storage battery; and S3, if the continuous discharging amount of the storage battery reaches the first discharging amount, controlling the relay to be switched off so as to enable the storage battery to stop supplying power to the low-voltage load. Whether the whole vehicle discharging signal is received or not is detected, if the whole vehicle discharging signal does not exist, the discharging condition of the storage battery is monitored, and therefore when the continuous discharging amount of the storage battery reaches the certain discharging amount, the relay is switched off, and the storage battery stops supplying power to the low-voltage load, and the storage battery is prevented from over discharging; and the discharging active protection function of the storage battery is achieved, and the storage battery is effectively protected.

Description

technical field [0001] The present invention relates to the field of vehicle technology, in particular to a control method and system for a vehicle. Background technique [0002] The battery of the vehicle is used to convert chemical energy into electrical energy, which can provide a strong direct current for the starter when the vehicle is started, and supply power to the electrical equipment of the vehicle when the vehicle is idling, and at the same time act as a large-capacity capacitor to protect the vehicle Electrical equipment. However, in the use of the battery, it is often encountered that the battery is used improperly, such as parking for a long time without disconnecting the positive and negative poles of the battery, causing the battery to feed power, and it is easy to make the vehicle unable to start next time. [0003] In related technologies, many vehicles are now equipped with a battery protection device, wherein the battery protection device achieves the pu...
