Ignition detection device and method for automobile

Abstract

The invention discloses an ignition detection device and an ignition detection method for an automobile. The method comprises the following steps: S1, detecting real-time voltage output by a storage battery; S2, if a vibration sensor detects a vibration signal, recording vibration signal information; S3, outputting low voltage which is lower than the voltage stably output by the storage battery at a certain time interval by an MCU (Microprogrammed Control Unit) processor; S4, judging the primary time interval of the real-time voltage output by the storage battery in the time interval of the low voltage is in the ignition voltage state of the automobile or not; S5, judging whether a recorded vibration signal of which the generation time interval is comprised in the time interval in which the real-time voltage output by the storage battery is in the ignition voltage state of the automobile exists or not, and judging that ignition operation is performed on the automobile if the vibration signal information exists. By adopting the ignition detection device and the ignition detection method for the automobile provided by the invention, a user can judge the ignition state of the automobile, so that the use of electronic equipment in a vehicle can be reduced consciously when the vehicle is in a non-ignition state, the power consumption of the storage battery is lowered, and the service life of the storage battery is prolonged.

Description

technical field [0001] The invention relates to a detection device and method, in particular to an automobile ignition detection device and method. Background technique [0002] At present, the power supply methods of electronic products in automobiles mainly include two methods. When the car is ignited, the motor supplies power to it, and when the car is not ignited, the battery supplies power to it. With the development of the automobile industry, automotive electronic products are increasing day by day. When the car is in the unignited state, if it is only for the electronic equipment in the car to supply power, the excessive power consumption will cause a large burden on the battery, and even cause the vehicle to fail to start normally. Therefore, the electronic equipment in the vehicle is not ignited. The state should be in a low power consumption state, such as entering a dormant or sleep state. In this state, the user should reduce the use of electronic equipment in t...

[0002] At present, the power supply methods of electronic products in automobiles mainly include two methods. When the car is ignited, the motor supplies power to it, and when the car is not ignited, the battery supplies power to it. With the development of the automobile industry, automotive electronic products are increasing day by day. When the car is in the unignited state, if it is only for the electronic equipment in the car to supply power, the excessive power consumption will cause a large burden on the battery, and even cause the vehicle to fail to start normally. Therefore, the electronic equipment in the vehicle is not ignited. The state should be in a low power consumption state, such as entering a dormant or sleeping state. In this state, the user should reduce the use of electronic equipment in the car, which requires the user to know in advance whether the vehicle is in the ignition state.
