Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a vehicle control method including:
step S101: and acquiring hydrogen data of a gas transmission pipeline between a hydrogen adding port of the vehicle and the hydrogen storage container.
Step S102: and judging whether the vehicle is in a hydrogen injection state currently according to the hydrogen data, and if so, shielding an output signal of an accelerator pedal of the vehicle so that a user cannot drive the vehicle through the accelerator pedal.
For step S101, in a preferred embodiment, the acquiring hydrogen data of the gas transmission pipeline between the hydrogen inlet of the vehicle and the hydrogen storage container specifically includes: and acquiring the hydrogen pressure rise of the gas transmission pipeline within a preset time. The judging whether the vehicle is currently in a hydrogen injection state according to the hydrogen data specifically comprises: and judging whether the rising amount of the hydrogen pressure exceeds a preset threshold value, if so, judging that the vehicle is in a hydrogen injection state currently.
Specifically, a pressure sensor is arranged in a gas transmission pipeline between a hydrogenation port of a vehicle and a hydrogen storage container and used for detecting pressure data in the gas transmission pipeline; before the vehicle control method is executed, whether the whole vehicle is powered on or not is detected, if the whole vehicle is in a power-off state, a power system of the vehicle is in a closed state at the moment, and the vehicle cannot move in a running mode, so that the situation that the vehicle is displaced due to the fact that a user mistakenly steps on an accelerator pedal is not generated no matter whether the vehicle is in a hydrogen injection state, and at the moment, the vehicle control method does not need to be executed. If the whole vehicle is powered on, detecting whether the vehicle speed is 0 or not at the moment, and if not, indicating that the vehicle is in a running state, wherein the vehicle cannot be hydrogenated in the running state, so the vehicle control method is not required to be executed, and only when the vehicle is powered on and the vehicle speed is equal to 0, the vehicle control method is started to be executed at the moment.
The pressure sensor collects the hydrogen pressure of the high-pressure pipeline (namely the gas transmission pipeline) every preset time T to obtain a hydrogen pressure value; the hydrogen pressure rise in the preset time period T is calculated according to the hydrogen pressure value acquired by the sensor, if the hydrogen pressure rise exceeds a preset threshold value, the vehicle is judged to be in a hydrogen injection state at present, the output signal of an accelerator pedal of the vehicle is shielded, and therefore the vehicle cannot move even if a user mistakenly steps on the accelerator pedal, a hydrogenation gun of hydrogenation equipment cannot be separated from a hydrogenation port of the vehicle when hydrogen is injected, and hydrogen leakage is avoided to guarantee the hydrogenation safety of the vehicle.
Another embodiment of the present invention provides a vehicle controller for executing any one of the vehicle control methods of the present invention described above.
As shown in fig. 2, another embodiment of the present invention provides a vehicle hydrogenation monitoring system, including: a pressure sensor, a hydrogenation controller and a vehicle controller;
the pressure sensor is used for collecting the hydrogen pressure value of the gas transmission pipeline every preset time and transmitting the collected hydrogen pressure value to the hydrogenation controller;
the hydrogenation controller is used for calculating the hydrogen pressure rise amount within the preset time according to the hydrogen pressure value and then transmitting the hydrogen pressure rise amount to the vehicle controller;
and the vehicle controller is used for judging whether the vehicle is in a hydrogen injection state currently or not according to the hydrogen pressure rise, and if so, shielding an output signal of an accelerator pedal of the vehicle so that a user cannot drive the vehicle through the accelerator pedal.
In a preferred embodiment, the vehicle controller is further configured to detect an operating state of a vehicle, and then send a hydrogen detection instruction to the hydrogen controller when it is determined that the vehicle is in a stationary state and the entire vehicle is powered on, so that the hydrogen controller controls the pressure sensor to start detecting when receiving the hydrogen detection instruction.
The specific working principle of the vehicle hydrogenation monitoring system is as follows:
the method comprises the steps that firstly, a vehicle controller detects the vehicle state of a vehicle, firstly, whether the whole vehicle of the vehicle is electrified or not is detected, if the whole vehicle is in the power-off state, a vehicle power system is in the closed state at the moment, the vehicle cannot move, therefore, the situation that the vehicle sends displacement due to the fact that a user mistakenly steps on an accelerator pedal is avoided no matter whether the vehicle is in the hydrogen injection state, and vehicle hydrogenation monitoring is not needed. If the whole vehicle is powered on, detecting whether the vehicle speed of the vehicle is 0 or not at the moment, and if not, indicating that the vehicle is in a running state, wherein the vehicle cannot be hydrogenated in the running state, and at the moment, the vehicle hydrogenation monitoring is not needed.
When the fact that the whole vehicle is electrified and the vehicle speed is equal to 0 is detected, the vehicle is likely to hydrogenate, the vehicle controller sends a hydrogen detection instruction to the hydrogenation controller, and the hydrogenation controller starts to control the pressure sensor to detect the hydrogen pressure when receiving the hydrogen detection instruction.
The pressure sensor collects the hydrogen pressure of the high-pressure pipeline (namely the gas pipeline) every preset time T to obtain a hydrogen pressure value, and then the hydrogen pressure value is transmitted to the hydrogenation controller. The hydrogenation controller calculates the hydrogen pressure rise within the preset time T according to the hydrogen pressure value acquired by the sensor, and then transmits the hydrogen pressure rise to the vehicle controller. The vehicle controller judges whether the rising amount of the hydrogen pressure exceeds a preset threshold value, if so, the vehicle is judged to be in a hydrogen injection state at present, an output signal of an accelerator pedal of the vehicle is shielded, so that the vehicle cannot move even if a user steps on the accelerator pedal by mistake, and a hydrogenation gun of the hydrogenation equipment cannot be separated from a hydrogenation port of the vehicle when hydrogen is injected, so that hydrogen leakage is avoided, and the hydrogenation safety of the vehicle is guaranteed. If the rising amount of the hydrogen pressure does not exceed the preset threshold value, the vehicle is judged to be in a non-hydrogenation state at the moment, the vehicle controller does not process the hydrogen pressure, and the vehicle can normally start to run through the self-driving system.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
