Abstract
The utility model discloses an electric vehicle noise analog device which is capable of intuitively judging a vehicle state and also reminding foot passengers during driving. The electric vehicle noise analog device comprises a CAN (Controller Area Network) bus for transferring messages, a signal processing system for processing a detection signal, a sound generating device for stimulating various noises, a speed sensor for detecting speed, and an acceleration sensor for detecting acceleration; the speed sensor and the acceleration sensor are respectively connected with the signal processing system; and the signal processing system is connected with the sound generating device through the CAN bus. The electric vehicle noise analog device has the beneficial effects that the vehicle state is intuitively judged by a driver; the enjoyment of driving is enhanced; the foot passengers are can be reminded in time when an electric vehicle is driven; and the foot passengers are prevented from being frightened when the electric vehicle is noiselessly and suddenly driven backwards.
Description
Technical field
The utility model relates to electronlmobil manufacturing technology field, refers in particular to a kind of electronlmobil noise simulator.
Background technology
Development along with electric vehicle engineering, electronlmobil certainly will progressively replace from now on the traditional combustion engine automobile as a kind of environmental protection, energy-conservation new-energy automobile, the large characteristics of one are that noiselessness pollutes, and almost can reach in the process of moving fully quietly state.But along with going deep into of understanding, people recognize that gradually fully quietly driving environment is not meddlesome entirely yet.When electric vehicle drive accelerates, judge the driver of throttle opening for the roar of getting used to hearing engine engine, fully quietly electronlmobil can't provide judgement on the direct sense organ to them; In addition, when the quiet electronlmobil of driving crosses the roadside pedestrian fast, because the pedestrian does not hear in advance that the back has automobile to cross, and tends to make the pedestrian to get a fright.
Chinese patent Granted publication number: CN 1307986A, August 15 calendar year 2001 Granted publication day, a kind of efficient accumulator car without environment pollution is disclosed, it cancels driving engine on original roadlice basis, clutch transmission increases subminiature turbine engine, electrical generator, accumulator group charger, centrifugal type automatic clutch, DC motor forms.The weak point of this utility model is, reduced as much as possible the noise of electronlmobil, so that chaufeur can not be judged the throttle opening by the roar of hearing engine engine, and when the quiet electronlmobil of driving crosses the roadside pedestrian fast, tend to make the pedestrian to get a fright, increased the danger coefficient of electronlmobil.
The utility model content
The utility model is in order to overcome electronlmobil in the prior art because do not have noise so that chaufeur can not carry out intuitive judgment to vehicle-state and be easy to cause the deficiency of scaring to the pedestrian when travelling, and provides a kind of chaufeur can carry out intuitive judgment to vehicle-state and can remind pedestrian's electronlmobil noise simulator when travelling.
To achieve these goals, the utility model is used in lower technical scheme:
A kind of electronlmobil noise simulator of the present utility model, comprise the CAN bus that transmits for information, for the treatment of the signal handling equipment of detection signal, be used for simulating the sound generating apparatus of various noises, for detection of the speed sensor of speed with for detection of the acceleration pick-up of acceleration/accel, described speed sensor and acceleration pick-up respectively connect signal handling equipment, and described signal handling equipment connects sound generating apparatus by the CAN bus.
Described speed sensor and acceleration pick-up connect respectively signal handling equipment, speed sensor is used for the picking rate signal, acceleration pick-up is used for gathering acceleration signal, send signal to comparison that signal handling equipment is carried out speed and acceleration/accel, described signal handling equipment connects sound generating apparatus by the CAN bus, sends the signal after relatively to sound generating apparatus by the CAN bus and sends different sound.When electronlmobil was in acceleration mode, sound generating apparatus sent the roar when being similar to the driving engine acceleration; When electronlmobil does not accelerate but the speed of a motor vehicle when surpassing a certain setting speed of a motor vehicle, sound when sound generating apparatus sends and is similar to internal-combustion engines vehicle and at the uniform velocity travels has so just realized reminding when chaufeur carries out intuitive judgment, electric automobile during traveling to vehicle-state pedestrian's purpose.
As preferably, described speed sensor is installed in the electric automobile gear-box, is convenient to so real-time acquisition speed signal and sends timely signal handling equipment to.
As preferably, described acceleration pick-up is installed in the electric automobile gear-box, is convenient to so real-time obtaining acceleration signal and send timely signal handling equipment to.
As preferably, described sound generating apparatus is comprised of loud speaker, loud speaker can be divided into multiple loud speaker by the frequency difference, can carry out different sounding according to speed signal or the acceleration signal of appointment by combination like this, satisfies the requirement of unlike signal being used alternative sounds.
As preferably, described sound generating apparatus is installed in the electric vehicle cabin, is convenient to like this chaufeur vehicle-state is carried out intuitive judgment.
The beneficial effects of the utility model are, so that chaufeur carries out intuitive judgment to vehicle-state, have improved the enjoyment of driving, and can in time remind the pedestrian during electric automobile during traveling, avoid electronlmobil quiet cross from behind suddenly the time, cause scaring to the pedestrian.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: 1.CAN bus, 2. signal handling equipment, 3. sound generating apparatus, 4. speed sensor, 5. acceleration pick-up.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1, a kind of electronlmobil noise simulator, comprise the CAN bus 1 that transmits for information, for the treatment of the signal handling equipment 2 of detection signal, be used for simulating the sound generating apparatus 3 of various noises, for detection of the speed sensor 4 of speed with for detection of the acceleration pick-up 5 of acceleration/accel, described speed sensor 4 is connected with acceleration pick-up and is connected respectively signal handling equipment 2, and described signal handling equipment 2 connects sound generating apparatus 3 by CAN bus 1.Described speed sensor 4 is installed in the electric automobile gear-box.Described acceleration pick-up 5 is installed in the electric automobile gear-box.Described sound generating apparatus 3 is comprised of loud speaker.Described sound generating apparatus 3 is installed in the electric vehicle cabin.
When electric automobile during traveling, acceleration pick-up 4 on the wheel and speed sensor 5 are passed to signal handling equipment 2 with the speed signal and the acceleration signal that collect, signal handling equipment 2 judges by the processing to speed signal and acceleration signal whether electronlmobil is in acceleration mode or whether the speed of a motor vehicle surpasses a certain setting value.When electronlmobil is in acceleration mode, can trigger sound generating apparatus and send roar when being similar to driving engine and accelerating, the intuitive judgment to the driver provides vehicle-state has also improved Driving simultaneously; When electronlmobil does not accelerate but the speed of a motor vehicle when surpassing a certain setting speed of a motor vehicle (such as 60km/h), trigger sound generating apparatus and send sound when being similar to internal-combustion engines vehicle and at the uniform velocity travelling, electronlmobil just can remind the pedestrian to note dodging when crossing the pedestrian like this; And when acceleration/accel or speed were changed from small to big, the sound that sound generator sends also changed from weak to strong.
