Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

As shown in Fig. 1, the auto parts closing reminder system of the present invention includes an accessory state detection module M1, an ignition state detection module M2, a side door state detection module M3, and an alarm control module M4, wherein the accessory state detection module M1 is used to receive a characterization The auto accessory switch is in the closed state of the accessory opening signal, and is used to receive the accessory closing signal indicating that the auto accessory switch is in the off state; the ignition state detection module M2 is used to receive the key that indicates that the ignition key is pulled out from the ignition lock. signal, and is used to receive the key insertion signal indicating that the ignition key is inserted into the ignition lock; the side door state detection module M3 is used to receive the side door opening signal indicating that the driver’s side door is opened, and is used to receive the side door closing signal indicating that the driver’s side door is closed ; The alarm control module M4 is used when the accessory state detection module receives an accessory turn-on signal indicating that the auto accessory switch is in a closed state (for example, any one of the small light switch K3 and the headlight switch K4 in FIG. 2 is in a closed state) , if the ignition state detection module receives the above-mentioned key pull-out signal, and the side door state detection module receives the above-mentioned side door opening signal, then output an alarm control signal to control the corresponding alarm B1 as shown in Figure 2 to give an alarm prompt, the Buzzer can be selected for alarm B1. Here, as shown in Figure 2, when the small light switch K3 is closed, the body control module BCM will control the small light L1 to light up through the small light relay R1, and when the headlight switch K4 is closed, the body control module BCM will pass the front The headlight relay R2 controls the headlight L2 to light up.

The working principle of the reminder system of the present invention is:

When the ignition key is inserted into the ignition lock to output the key insertion signal, the alarm control module M4 will not output the alarm control signal under any circumstances; when the driver's side door is closed and the side door close signal is output, the alarm control module M4 will not output the alarm under any circumstances control signal;

When the driver pulls out the ignition key to output the key pull-out signal, if the auto parts switch is in a closed state at this moment, if the driver opens the driver's side door and outputs the side door open signal, then the alarm control module M4, for example, outputs a high-voltage pulse signal The alarm control signal is used to drive the alarm B1 inside the cab to act; if the driver does not disconnect the auto parts switch according to the alarm prompt, the alarm control module M4 will output the alarm control again when the driver opens the driver's side door when he gets on the car next time. The signal drives the alarm B1 inside the cab to act again, reminding the driver that the corresponding auto parts switch is currently in the closed state.

The above-mentioned alarm control module M4 stops outputting the alarm control signal if any stop alarm event is detected during the period of outputting the alarm control signal. The stop alarm event may include receiving the above-mentioned accessory closing signal, receiving the above-mentioned key insertion signal, receiving the above-mentioned side door closing signal, and outputting an alarm control signal exceeding a preset alarm time. The alarm time can usually be selected as 10s-50s. For example, it can be further selected as 30s.

The above-mentioned alarm system can be implemented in the body control module BCM as shown in FIG. 2 . In addition, the above-mentioned auto parts are especially small lights, headlights, electric windows and the like.

As shown in Figure 2, the system of the present invention can also include, for example, a normally open push button switch as the key insertion switch K1, the key insertion switch K1 is electrically connected to the ignition state detection module M2 (specifically, the signal input end of the module) and the Between irons, the positional relationship between the button part of the key insertion switch K1 and the key hole of the ignition lock is: when the ignition key is fully inserted into the key hole, push the button part of the key insertion switch K1 to the position where the key insertion switch is closed, so that A key insertion signal is output when the ignition key is fully inserted into the key hole, and a key removal signal is output when the key insertion switch is pulled out of the key hole.

The positional relationship between the key insertion switch K1 and the key hole of the ignition lock can be: the button portion of the key insertion switch K1 is opposite to the key hole in the insertion direction of the ignition key; or, as shown in Figure 3, the button portion 2 The direction of movement is perpendicular to the insertion direction of the ignition key KS, which requires the button part 2 to be provided with a driving slope 21 matched with the ignition key KS to push the button part 2 to move through the driving slope 21 when the ignition key KS is inserted into the keyhole.
