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

Embodiment 1

[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;

[0060] - gearbox 8, for changing the transmission ratio, which is provided with ...

Embodiment 3

[0074] The rest is the same as the second embodiment, the difference is that the motor has multiple speed gears, and the main control unit controls the motor to start at a low speed gear and continuously switch the speed gear according to the corresponding control mode and vehicle speed range. And control the gearbox to start with a low transmission ratio gear and continuously switch the acceleration mode of the transmission ratio gear to control the electric vehicle to accelerate with matching acceleration characteristics.

[0075] The following describes the working process of the intelligent acceleration and sound effect control system of the above-mentioned electric vehicle in this embodiment.

[0076] 1) The driver selects the control mode through the control panel;

[0077] 2) The driver accelerates through the accelerator operating device;

[0078] 3) The main control unit receives the control mode selection information and acceleration information, and controls the el...

Abstract

The invention discloses an intelligent acceleration and sound effect control system for an electric vehicle, which comprises a main control unit connected with an acceleration operating device, and under each control mode of the main control unit, the acceleration characteristics and engine sound of the electric vehicle are respectively simulated The acceleration characteristics and engine sound of a supercar. The main control unit is also connected with a control panel and a sounding device. The main control unit receives the control mode selection information and then receives the acceleration information, and then controls the electric vehicle to accelerate and control with the matching acceleration characteristics. The sound generator emits a matching engine sound. Artificial intelligence is used to simulate the acceleration characteristics and engine sound effects of various supercars. On the one hand, it can remind passersby to detect the presence of a car in time and pay attention to safety. On the other hand, it can make high-end electric vehicles more fun to drive and increase their market appeal.
