Abstract
The invention discloses a control method for automatic water discharging of a diesel oil filter, which comprises the following steps: the controller receives water level height information in the diesel filter in real time and judges whether the water level height information reaches an alarm value. When the water height information reaches the alarm value, the controller sends an alarm signal to a driver, and the driver presses a safe water discharging confirmation switch. When the driver presses the safe water discharging confirmation switch, the controller judges whether the vehicle is in a safe state. When the vehicle is in a safe state, the controller controls a water drain valve in the diesel filter to automatically drain water. And when the water level height information in the diesel filter reaches a target value, the controller controls the water drain valve to be closed. Therefore, according to the control method for automatically discharging water of the diesel oil filter, a driver can automatically discharge water in the cockpit, and the water discharge valve is immediately and automatically closed when the water discharge is completed, so that one drop of diesel oil is not wasted, and potential safety hazards are avoided.

Background
In the normal running process of the vehicle engine, the controller can detect the water accumulation state in the diesel filter according to information fed back by the water alarm sensor in the diesel filter, and sends the water accumulation state information to a vehicle instrument panel through messages. When the accumulated water reaches the alarm value, the water alarm warning lamp on the instrument panel of the whole vehicle is normally on, so that a driver is reminded to drain water. If the driver does not drain, the torque output of the engine can be immediately limited in order to ensure the service life of the engine, so that the vehicle cannot normally run. Therefore, in order to ensure that the vehicle can normally run, a driver needs to find a safe area and stop the vehicle, and immediately carries out water discharging operation.
The prior technical scheme is as follows: after finding a safe area and stopping a vehicle, a driver needs to get off to find a diesel filter on an engine compartment, manually unscrew a drain valve of the diesel filter to perform water drainage operation, and then immediately screw down the drain valve when starting to flow diesel after visually observing the water drainage, so that more diesel is prevented from being wasted.
In the prior art, the following disadvantages exist:
1. when water is drained, a driver manually drains water according to the arrangement position of the diesel oil filter in the engine compartment (some vehicles even need to shake up a vehicle cab), which is very inconvenient and bad in experience of the driver;
2. the water in the diesel oil filter can be identified to be discharged after the diesel oil flows out, so that the waste of the diesel oil is caused, and meanwhile, the safety hidden trouble is brought.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
