Multi-functional low-speed sound simulating reminder device for pure electric vehicle

Abstract

The invention discloses a multi-functional low-speed sound simulating reminder device for a pure electric vehicle aiming at the problem that the pure electric vehicle is low in motor sound in a low-speed start-up stage and cannot supply corresponding warnings to surrounding pedestrians and vehicles. The multi-functional low-speed sound simulating reminder device comprises a power supply module, a program module, a voice module, a power amplifier module, a speaker module and a CAN receiver, the program module is connected with the power supply module, the CAN receiver and the voice module, the voice module is connected with the power amplifier module and the speaker module, the sound simulating reminder device is also connected with a meter slave module and a meter master module, the program module reads a vehicle speed signal through the CAN receiver, the program module is connected with a reverse signal line, a left turning signal line and a right signal line through hard lines, and after receiving the corresponding signals, the corresponding content is warned by voice. According to the multi-functional low-speed sound simulating reminder device for the pure electric vehicle, when the vehicle is driven at a high speed after the high voltage, or when the vehicle speed is lower than 20 Km / h, or when the vehicle is reversed or turns left or turns right, different voice warnings appear to remind the surrounding pedestrians and the vehicles of collision.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicle safety, in particular to a multifunctional low-speed sound simulation reminder device for pure electric vehicles. Background technique [0002] With the implementation of the policy of vigorously promoting pure electric vehicles by the country, the output of pure electric vehicles has shown explosive growth. However, due to the low sound of motor starting and running, pure electric vehicles at this stage cannot provide effective warnings to surrounding pedestrians, etc. Cause traffic accidents, and the sound prompting device on the car is relatively single, only when reversing, the reversing buzzer sounds, and there is no steering sound prompt, etc., which is very inhumane. [0003] In order to solve this problem, we have designed a multi-functional sound simulation reminder device, which can be used during the idling stage after the high-voltage electricity is installed on the whole...
