Optionally, the component of the alcohol gas sensor is tin dioxide. The tin dioxide gas-sensitive resistor is a semiconductor gas-sensitive resistor, belongs to an N-type semiconductor, contains oxygen vacancies or tin gap ions in the semiconductor, is in an oxygen ion vacancy state in a normal state, and when the tin dioxide gas-sensitive resistor encounters a reducing gas such as alcohol which has poor dissociability and is easy to lose electrons, electrons can migrate from the gas to the tin dioxide semiconductor, so that the number of carriers on the semiconductor is increased, and the resistance is reduced. This particular crystal structure determines its usefulness as an excellent gas-sensitive resistive material. With the oxidation-reduction reaction of the tin dioxide surface and alcohol, the resistance characteristic of the gas-sensitive resistor is changed, the voltage and current at the two ends of the gas-sensitive resistor are correspondingly changed, the alcohol concentration in the exhaled gas and the alcohol concentration in the blood of a human body have a certain proportion relation, and the gas with different alcohol concentrations can cause the gas-sensitive resistor to generate analog voltage signals with different intensities, and the corresponding digital voltage signals are output through amplification and analog-digital conversion.

208. The vehicle switches to an unlocked state in response to the alcohol concentration meeting the start condition.
The unlock state refers to a state in which the vehicle is allowed to start and run. In the embodiment of the application, if the vehicle determines that the alcohol concentration meets the starting condition, it is indicated that the driver is not drinking alcohol and can drive the vehicle, so that the vehicle is switched to the unlocking state.
