Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, below in conjunction with embodiment and cooperate attached
Figure is explained.
The most critical design of the present invention is: by separately designing different prompt tones to the driving status of vehicle respectively,
By optimize voice control module input signal, according to the speed of input, transmission gear, brake pedal status signal,
The prompt tone of different type, different volumes is issued to vehicle different direction.
The present invention relates to a kind of low vehicle speeds reminding methods, comprising the following steps:
When vehicle is put into forward gear, in acceleration or the state of advancing, and speed is less than or equal to 30km/h and is greater than 0km/h
When, the first prompt tone is issued to vehicle front, the volume of first prompt tone is directly proportional to speed height；When the speed of vehicle
When greater than 30km/h, the first prompt tone disappears；
When vehicle is put into forward gear, it is in advance deceleration regime, and when speed is less than or equal to 25km/h, is sent out to rear of vehicle
Second prompt tone out；The volume of second prompt tone is directly proportional to speed height；
When vehicle is put into forward gear, when remaining static, prompt tone disappears；
When vehicle is linked into reverse gear, is in static or fallback state, third prompt tone is issued to rear of vehicle.
In above-mentioned low vehicle speeds reminding method, by the way that different prompts is separately designed to the driving status of vehicle respectively
Sound is believed by optimizing the input signal of voice control module according to the state of the speed of input, transmission gear, brake pedal
Number, the prompt tone of different type, different volumes is issued to vehicle different direction, obtains pedestrian and vehicle outside vehicle in time
Information warning and actively avoid；When vehicle low speed is forward at the uniform velocity or when giving it the gun, i.e. gear hangs drive shift, brake pedal not by
When trampling, loudspeaker is arranged by vehicle front, the first prompt tone is issued to vehicle front, reminds front vehicles and pedestrian in time
Evacuation in time, avoids colliding；And when the vehicle is decelerating, i.e., extension drive shift, brake pedal pass through vehicle in when trampling state
Loudspeaker is arranged in rear, issues the second prompt tone to rear of vehicle, reminds the vehicle deceleration at rear simultaneously to maintain safe distance in time, prevent
Only knock into the back；And when vehicle is linked into reverse gear, third prompt tone directly is issued to vehicle rear, front vehicle is reminded to maintain safe distance in time,
And under reverse gear state, without the concern for vehicle speed condition, keep uniform third prompt tone；The present invention is changed by the above method
Into the generation of the safety accidents such as personal injury and vehicle collision can be prevented, so that it is guaranteed that the operational safety of new-energy automobile.
Further, it in above-mentioned low vehicle speeds reminding method, further comprises the steps of: and is mentioned according to vehicle external environment adjusting first
Show the level of sound volume of sound, the second prompt tone and third prompt tone.
Seen from the above description, equipment is acquired by the way that volume is arranged outside vehicle, is automatically controlled by acquisition environmental volume
The level of sound volume of prompt tone avoids volume excessive as far as possible while ensuring that prompt tone is not interfered or covered by ambient noise
And cause goers outside vehicle or the scaring of driver.Level of sound volume can also be by driver on instrument board, steering wheel or console
It is manually controlled.
Further, in above-mentioned low vehicle speeds reminding method, the volume of the third prompt tone is greater than the first prompt
The max volume of sound and the second prompt tone.
The volume of third prompt tone is maximum in the present invention, this is because rear-end collision frequency is higher in traffic accident, when
Vehicle is linked into when reversing gear, it is accordingly required in particular to remind front vehicle that can give warning in advance more at a distance.
Further, it in above-mentioned low vehicle speeds reminding method, further comprises the steps of: when vehicle turning, to vehicle side
Side issues the 4th prompt tone.
Further, in above-mentioned low vehicle speeds reminding method, the pedestrian when front part of vehicle and vehicle are further comprised the steps of:
Distance be less than preset value when, trigger the first prompt tone；When the pedestrian of vehicle rear is less than preset value at a distance from vehicle, touching
Send out the second prompt tone；When the pedestrian of side portion of vehicle is less than preset value at a distance from vehicle, the 4th prompt tone is triggered.
Fig. 1 is please referred to, the invention further relates to a kind of low vehicle speeds prompt systems, comprising:
Advance and accelerate cue module 1: for putting into forward gear when vehicle, in acceleration or the state of advancing, and speed is less than
When equal to 30km/h and being greater than 0km/h, the first prompt tone is issued to vehicle front, the volume and speed of first prompt tone are high
