Embodiment Construction
[0017] The specific embodiments of the present invention will be described in further detail by the description of the optimal embodiments.
[0018] The present application is mainly based on a combined instrument for a logic control method for a combined instrument sound and light safety belt without SBR without SBR. There is only a low-cost seat (canceled SBR), which has reached the sound function of the combination instrument seat belt alarm, achieving a reduction in the cost of the vehicle.
[0019] The traditional police seat belt alarm logic includes the key to hit the ON gear, and the speed of the vehicle speed is <10km / h. If the front passenger seat safety belt or has not been occupied by adults, the visual alarm symbol on the combined instrument It is not light and the sound alarm device is not called; if the front passenger seat belt is not systematic, the combined instrument visual alarm symbol flashes (flashing mode: 500ms ON, 500MS OFF) but no sound alarm prompt unt...

The invention discloses a safety belt detection reminding method based on a combination instrument, which comprises the following steps of: (1) when a vehicle key is in an ON gear, judging whether a passenger gets on a copilot and a rear row by detecting the opening and closing states of a copilot door and a rear row door; if it is judged that someone gets on the vehicle, the step (2) is executed; (2) judging whether a safety belt buckle corresponding to the getting-on position of a person is inserted into a clamping seat or not; if not, starting combination instrument safety belt alarm reminding; if so, entering step (3); and (3) the vehicle door state is monitored in real time, and if the vehicle door opening and closing state is changed, the step (2) is executed again. The safety belt unfastening warning device has the advantages that the safety belt unfastening warning reminding signal is given after comprehensive judgment according to the signals of the vehicle door state, the ON state, whether the safety belt plug is inserted into the socket or not and the like, and therefore safety belt unfastening reminding can be achieved on the basis that an SBR module is omitted.
Description
Technical field [0001] The present invention relates to the field of intelligent driving, and in particular, to a method of combined instrument that realizes a safe alarm without seat pressure sensor. Background technique [0002] The development of the modern automotive industry, the automotive smart cockpit is increasingly high, and people pay more and more attention to the safety of the car. Safety is divided into active security and passive safety. The role of automotive active safety is to monitor and avoid the possibility of vehicle out of control and traffic accidents, improve the driving stability of the car, such as the most typical automatic driving and active brake system. The role of passive safety is to reduce the damage of occupants in the car, such as seat belts and airbags as possible when the vehicle has occurred. Whether the seat belt is well promoted and prompts the driving passengers. It has a very critical role in the driver and passengers. When there is no s...
