2) When the vehicle starts and the speed of the pure electric vehicle and the plug-in hybrid electric vehicle is lower than 20km/h, the pure electric vehicle and the plug-in hybrid electric vehicle can give out proper prompting sound to personnel outside the vehicle.

The warning tone control device described in this patent needs to have the following functions:

1) a vehicle right turn prompting function;

2) the low-speed prompting function of the electric automobile;

3) and a vehicle reversing prompt function.

In the prior art, most of the related schemes of the warning tone control device are independent schemes, such as a commercial vehicle turning pedestrian warning system and a control method (CN108263313A) thereof, an electric vehicle low-speed warning tone device (CN207790474U) and an automobile reversing double-flashing-light warning device (CN204586651U), the vehicle is required to be provided with at least two or three warning tone devices, the arrangement scheme is complex, and the system cost is increased. Therefore, how to integrate several warning tone functions into the same control device, and reduce the number of warning tone control devices while meeting the requirements of GB 7258 and functions is a very important issue.

Disclosure of Invention

The utility model aims at providing a multi-function vehicle suggestion sound control device just lies in to above-mentioned prior art not enough, provides a vehicle suggestion function of turning right, electric automobile low-speed prompt facility and the prompt facility integration of backing a car at a suggestion sound control device, has satisfied GB 7258 to the requirement of vehicle suggestion of turning right and electric automobile low-speed suggestion, reaches simultaneously and reminds the pedestrian to notice, reduces the incidence of traffic accident, has improved pedestrian's safety greatly.

The utility model aims at realizing through the following technical scheme:

a multifunctional automobile prompting sound control device is externally connected with a storage battery, an ignition switch, a steering switch, a position lamp switch, a reversing lamp switch and a vehicle speed sensor. The control device mainly comprises a power supply processing module, a switch acquisition module, a vehicle speed acquisition module, an audio processing module, a buzzer and a central processing unit (MCU). The power supply processing module is connected with the anode and the cathode of the storage battery and supplies power to the central processing unit MCU and other modules; the switch acquisition module is connected with an ignition switch ON gear, a left/right steering switch, a position lamp switch and a reversing lamp switch and sends acquired switch signals to the MCU; the vehicle speed acquisition module is connected with the vehicle speed sensor and sends an acquired vehicle speed signal to the MCU; the central processing unit MCU carries out logic processing through receiving input signals of the switch acquisition module and the vehicle speed acquisition module, controls the audio processing module to execute corresponding operation, and controls the buzzer to enter a reverse prompting mode, a right turn prompting mode and a low speed prompting mode according to the instruction of the central processing unit MCU.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the utility model discloses multi-functional car warning sound controlling means has satisfied GB 7258 and has required to vehicle turn right suggestion and electric automobile low-speed suggestion, has realized the prompt facility that backs a car simultaneously, when satisfying the regulation requirement, has reduced the kind of part, has reduced the system cost simultaneously.

Drawings

FIG. 1 is a schematic circuit diagram of a multi-function vehicle warning tone control device according to the present invention;

fig. 2 is a functional flow chart of the multi-function vehicle warning tone control device of the present invention.

In the figure, 1, a storage battery 2, an ignition switch 3, a steering switch 4, a position lamp switch 5, a reversing lamp switch 6, a vehicle speed sensor 7, a power supply processing module 8, a switch acquisition module 9, a vehicle speed acquisition module 10, an audio processing module 11, a buzzer 12 and a central processing unit MCU (microprogrammed control unit).

Detailed Description

As shown in FIG. 1, the utility model discloses multi-functional car warning sound controlling means, external connection battery 1, ignition switch 2, steering switch 3, position lamp switch 4, backup lamp switch 5 and speed sensor 6. The control device is internally composed of a power supply processing module 7, a switch acquisition module 8, a vehicle speed acquisition module 9, an audio processing module 10, a buzzer 11 and a central processing unit MCU 12.

The power supply processing module 7 is connected with the anode and the cathode of the storage battery 1 and supplies power to the MCU12 and other modules; the switch acquisition module 8 is connected with the ON gear of the ignition switch 2, the left/right steering switch 3, the position lamp switch 4 and the reversing lamp switch 5, and transmits acquired switch signals to the MCU 12; the vehicle speed acquisition module 9 is connected with the vehicle speed sensor 6 and sends an acquired vehicle speed signal to the central processing unit MCU 12; the central processing unit MCU12 carries out logic processing by receiving input signals of the switch acquisition module 7 and the vehicle speed acquisition module 9, and controls the audio processing module 10 to execute corresponding operations, and the audio processing module 10 controls the buzzer 11 to enter a reverse prompting mode, a right turn prompting mode and a low speed prompting mode according to instructions of the central processing unit MCU 12.

As shown in fig. 2, the utility model discloses multi-functional car suggestion sound controlling means's working process does:

1) the ignition switch is switched ON, and when the reversing light switch is switched ON, the control device executes a reversing prompt tone control function to remind pedestrians behind the vehicle to avoid.

2) The ON gear of the ignition switch is switched ON, and when the reversing light switch is switched off, the control device exits the reversing prompt mode; at this time, if the right steering switch is turned on, the control device enters a vehicle right turn prompting mode, and executes a daytime right turn prompting tone control function and a nighttime right turn prompting control function according to the position lamp switch state, thereby reducing traffic accidents caused by blind areas of drivers when the vehicle turns right.

3) The ignition switch is switched ON, when the reversing light switch is switched off and the right steering switch is switched off, and the vehicle runs at a speed lower than 20km/h, the control device executes a low-speed prompt control function to remind pedestrians with sound, so that the attention of the pedestrians is attracted, and the safety of the pedestrians is greatly improved.
