Electric vehicle with traveling reminder and working method thereof

Abstract

The invention discloses an electric vehicle with a traveling reminder and a working method thereof and relates to the technical field of electric vehicles. The electric vehicle comprises a power drive system (1) comprising a drive-control circuit (3), a speed-governing operating mechanism (4) and a rotation system (5). The electric vehicle is characterized in that the traveling reminder (6) which simulates the traveling sound and / or vibration law of diesel motor vehicle according to the working condition of the power drive system (1) to perform traveling sound and / or vibration reminding is arranged and is provided with a signal sensor (7), a loudspeaker (8) and / or a vibrator (9) which are mutually connected or combined, and the signal sensor (7) is combined with the power drive system (1). During traveling, the electric vehicle can provide relatively quiet acoustical and / or haptical reminding for a driver or passengers, effectively stop traffic and driving potential safety hazard, satisfy the pleasant sensation and enjoyment in driving and is suitable for standardized generalization and application.

Description

Technical field [0001] The invention relates to an electric vehicle, in particular to an electric vehicle with a driving reminding device and a working method thereof. Background technique [0002] Electric vehicles generally include electric bicycles, electric power-assisted motorcycles, and electric vehicles. Due to their obvious advantages in energy saving and environmental protection, compared with internal combustion vehicles, they have a broad future market. The electric vehicle in the prior art includes an electric drive system, the electric drive system includes a drive control circuit, a speed regulating operating mechanism and a rotation system, and the drive control circuit includes a power supply subsystem, a speed control subsystem, etc.; the rotation system includes a drive motor, Drive subsystems and wheels, etc., the driving motor can also be used as a generator. Of course, sometimes the rotating system can also be equipped with a generator or even an interna...

Problems solved by technology

As a result, in these cases, electric cars either move slowly, delaying time and causing more congestion, or just honk, which is firstly against the relevant traffic rules in the city, and secondly in the environment. Cause one after another, harsh noise pollution

Obviously, for an electric vehicle, its quiet driving noise index cannot be truly reflected in the real life where the whistle is constantly honking; and when a quiet electric vehicle suddenly drives past a pedestrian, it is very easy to cause shock or discomfort to the pedestrian. safety factors;

[0005] Secondly, when the vehicle is stopped but the car key starts the internal combustion engine or the electric drive system is energized and ready to move, the internal combustion engine of the internal combustion vehicle runs continuously at idle speed, while the electric vehicle accelerates without touching the speed regulating operating mechanism. The drive motor is almost or stopped running. For electric vehicle drivers, there is no continuous and reliable reminder such as low-frequency, low-volume "hum" sounds or low-frequency, low-amplitude vibrations of internal combustion vehicles. Drivers often It is easy to be negligent and forget that the car is powered on and ready to move. Once the speed regulating operating mechanism is accidentally touched, the car will suddenly rush out and cause an accident;

[0006] Furthermore, when stepping on the accelerator to accelerate or overtake, electric vehicle drivers often cannot immediately and effectively feel the rapid engine roar that rapidly increases in frequency and volume as in internal combustion vehicles, including the accelerated and increased vibration. etc., so that the implementation of the acceleration action is inaccurate, which increases unsafe factors, and what is more unfavorable is that for a considerable number of drivers who pursue individuality or are accustomed to the driving sound and / or vibration rules of internal combustion vehicles, Much of the driving thrill and driving pleasure is lost

[0007] Electric vehicles in the prior art also generally have a key-on light reminder function for the driver, but the driving reminder method is monotonous, and even affects vision, and cannot be safely and perceptually reminded through hearing or touch, and the effect is extremely limited
