Problems solved by technology

[0002] Electric vehicles will gradually become the mainstream in the future, with the advantages of large torque, fast acceleration, low sound, and environmental protection. At present, the performance of electric vehicles is getting better and better. Some high-end electric vehicles (such as Tesla) start from a standstill to a speed of 100Km / h , as long as it takes less than 3 seconds, this kind of acceleration performance is not inferior to all kinds of supercars currently on the market, and it is a very superior performance for drivers. See figure 1 , is the acceleration curve of the electric vehicle Tesla. The acceleration characteristics of the electric vehicle are adjusted at the factory, fixed, single, and quiet. On the one hand, the lack of blood-pumping and rumbling engine sounds during acceleration greatly reduces the driving pleasure

[0033] see figure 2 , as shown in the legend, an intelligent acceleration and sound control system for electric vehicles, including:

[0034] - Control panel 1, used to obtain driver control mode selection information;

[0035] - Acceleration operating device 2, used to obtain driver acceleration information;

[0036] - The electric motor 3 is used to provide driving force, and it is provided with multiple speed gears;

[0037] -Sound generator 4 for engine sound

[0038] - the main control unit 5, which includes a database 51, a motor controller 52 and a sounding device controller 53, at least one set of acceleration characteristic parameters and at least one set of engine sounds are stored in the database 51, each set of engine sounds is obtained by using a typical vehicle speed Synthesis of lower engine voice samples produces a continuous range of engine running sounds;

[0039] - Power source 6 for providing energy;

[0040] Wherein, the control panel 1 and the acceler...

Embodiment 2

[0053] see Figure 4 , as shown in the legend, an intelligent acceleration and sound control system for electric vehicles, including:

[0054] - Control panel 1, used to obtain driver control mode selection information;

[0055] - Acceleration operating device 2, used to obtain driver acceleration information;

[0056] - Electric motor 3 for providing driving force;

[0057] - sounding device 4 for emitting engine sound;

[0058] - the main control unit 5, which includes a database 51, a motor controller 52, a sounding device controller 53 and a gearbox controller 54, at least one set of acceleration characteristic parameters and at least one set of engine sounds are stored in the database 51, each set of Engine sounds are synthesized using engine speech samples at typical vehicle speeds to generate a continuous range of engine running sounds;

[0059] - Power source 6 for providing energy;

Abstract

The invention discloses an intelligent acceleration and sound effect control system of an electric vehicle. The intelligent acceleration and sound effect control system comprises a main control unit which is connected with an acceleration operation device; under each control mode of the main control unit, the acceleration characteristics and engine sound of the electric vehicle respectively simulate the acceleration characteristics and engine sound of a super car; the main control unit is also respectively connected with a control panel and a sound production device; and the main control unitreceives control mode selection information and then receives acceleration information so as to control the electric vehicle to be accelerated according to matched acceleration characteristics as wellas control the sound production device to produce matched engine sound. Artificial intelligence is utilized for simulating the acceleration characteristics and engine sound effects of various super cars, so that on the one hand, pedestrians can be reminded to find vehicles in time to take care, and on the other hand, high-order electric vehicles have better driving pleasure and market attractiveness can be promoted.
