Embodiment 1

[0022] A passenger car gas safety control system provided by the present invention, such as figure 1 As shown, it includes: a vehicle controller, an air leakage detection module and an air leakage protection module, and the vehicle controller is connected to the air leakage detection module and the air leakage protection module.

[0023] The gas leakage detection module includes gas leakage detection sensors. The gas leakage detection sensors are respectively located at the gas storage cylinder, the gas transmission pipeline and the engine or fuel cell, and the signal of the gas leakage detection sensor is connected to the vehicle controller.

[0024] The power supply circuit of the air leakage detection sensor is provided with a main fire switch and a power supply relay of the air leakage detection sensor, and the power supply relay of the air leakage detection sensor is selectively powered under the control of the vehicle controller, thereby controlling the air leakage detect...

Embodiment 2

[0039] In order to provide better protection for the occupants in the case of gas leakage, for example, to give certain alarms to the occupants in the event of gas leakage, or to limit the state of the vehicle, another gas safety system for passenger cars provided by the present invention control system, such as image 3 As shown, on the basis of Embodiment 1, the system also includes an air leakage alarm display module and a vehicle power module.

[0040] The air leakage alarm display module mainly provides an alarm prompt to the occupants in the vehicle through the instrument panel of the passenger vehicle. When the gas leaks, the vehicle controller sends the control signal to the instrument panel through the CAN network, and the instrument panel analyzes the CAN message and gives a corresponding display or warning.

[0041] The vehicle power module and air leakage alarm display module are connected to the vehicle controller through the CAN network.

[0042] The vehicle po...

Abstract

The invention relates to the field of car safety control, in particular to a passenger car gas safety control system and method. The passenger car gas safety control system comprises a car controller,a gas leakage detection module and a gas leakage protection module, and the gas leakage protection module comprises a gas storage cylinder control valve and a protection gas storage cylinder controlvalve which are automatically controlled by the car controller. When gas leakage is detected, the car controller controls a gas storage cylinder solenoid valve to be closed and a protection gas storage cylinder solenoid valve to be opened through a high level signal, a car gas circuit is cut off, protection gas is quickly released to fight for more time for evacuating of personnel in a car, the situation that leaked gas makes contact with nearby fire, and consequently a fire disaster occurs is avoided, and the hidden danger of fire breaking out of the leaked gas is avoided.

Description

technical field [0001] The invention relates to the field of vehicle safety control, in particular to a passenger car gas safety control system and method. Background technique [0002] With the development of new energy, gas, gas-electric hybrid and fuel cell buses are slowly replacing traditional fuel buses, and the safety performance of such buses is the focus of current bus production. During the operation of the vehicle, in order to improve the safety performance, when a gas leak occurs in a certain part of the gas pipeline, the vehicle control system needs to take the initiative to take a safety protection measure, and timely transmit relevant information to the driver through sound and light alarms and other signals. crew and passengers. [0003] In order to improve the safety performance of this type of passenger car, timely discover and take measures when the gas leaks, a patent document with the publication number CN20462344U discloses a hybrid electric vehicle, i...
