Embodiment Construction
[0039] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0040] The invention aims to solve the problem that there are no protective measures for the personal safety of children in the car after the vehicle is locked, and can send an alarm signal to remind the driver after the driver leaves the car, thereby preventing children from being left in the car. Especially when a child is sleeping soundly in the car, by detecting the environment inside the car,...

The invention provides a vehicle living body detection module and a control method thereof, and the method comprises the steps: enabling a power supply module to indicate the power supply module to supply power to a detection unit when vehicle state information sent by a vehicle control module is received, forwarding the vehicle state information to the detection unit, enabling the detection unit to enter a standby mode from a power-off mode after the detection unit is powered on, the detection unit is used for receiving vehicle state information, judging whether a preset living body detection condition is met or not according to the vehicle state information, switching from a standby mode to a working mode when the preset living body detection condition is met, and performing living body detection in the working mode and outputting a living body detection result; receiving a living body detection result output by the detection unit and transmitting the living body detection result to the whole vehicle control module; and when a power-off configuration signal sent by the detection unit is received, the power module is forbidden to indicate the power module to stop supplying power to the detection unit, and the power-off configuration signal is sent by the detection unit when the detection unit meets the sleep condition. The electric quantity of the power supply is prevented from being continuously reduced due to the detection unit.
Description
technical field [0001] The invention relates to the field of automobile electronic control, in particular to a vehicle living body detection module and a control method thereof. Background technique [0002] At present, it is not uncommon for children to be suffocated to death after being forgotten by their parents in the car. In an outdoor environment with direct sunlight and closed doors and windows, the internal temperature of the car can reach the critical value of heat stroke within 15 minutes, which can lead to suffocation and death in severe cases. In order to avoid the occurrence of accidental stranded events during travel, a variety of in-vehicle liveness detection schemes are provided, especially when children are sleeping in the car, by detecting the environment in the car, once a danger is found, an alarm signal will be sent to the outside in time, for Children in cars provide a safer travel guarantee. The sensors used for in-vehicle liveness detection mainly i...
