Embodiment 1

[0052] refer to figure 1 , shows a flowchart of steps of an acceleration control method according to an embodiment of the present invention.

[0053] An acceleration control method provided by an embodiment of the present invention is mainly applied to a vehicle, especially a pure electric vehicle, to optimize the rapid acceleration performance of the vehicle before performing a rapid acceleration operation, which may specifically include:

[0054] Step 101: Obtain an acceleration request of a user, and the acceleration request includes an urgent acceleration request and a non-urgent acceleration request.

[0055] The acceleration control method provided by the embodiment of the present invention obtains the user's acceleration request and performs corresponding operations according to the user's acceleration request, so as to reduce the temperature of the drive module before the vehicle performs a rapid acceleration operation, so as to improve the rapid acceleration of the ve...

Embodiment 2

[0085] refer to Figure 4 , shows a schematic structural diagram of an acceleration control system according to an embodiment of the present invention. Such as Figure 4 As shown, the acceleration control system provided by the embodiment of the present invention is mainly used for vehicles, and the acceleration control system includes:

[0086] The acquiring module 50 is configured to acquire acceleration requests of users, and the acceleration requests include urgent acceleration requests and non-urgent acceleration requests.

[0087] The control module 60 is configured to control the thermal management system to perform a forced cooling operation on the drive module for a preset time when the acceleration request is the rapid acceleration request.

[0088] Specifically, by performing forced cooling on the driving module 10 of the vehicle, the driving module 10 of the vehicle can dissipate heat as soon as possible, so as to achieve the best performance during rapid acceler...

Abstract

The invention provides an acceleration control method and system and a vehicle. The method comprises the steps of obtaining an acceleration request of a user, and under the condition that the acceleration request is a rapid acceleration request, executing a forced refrigeration operation for a preset time, so that the temperature of a driving module is rapidly reduced. The temperature of the driving module of the vehicle is collected to judge whether the temperature of the driving module is lower than or equal to the preset temperature, and the rapid acceleration performance state signal of the vehicle is fed back according to the temperature, so that a user is helped to know the rapid acceleration condition of the vehicle. According to the invention, the acceleration request of the user is obtained, and forced refrigeration is performed on the driving module before the rapid acceleration operation is performed, so that the driving capability of the driving module can be improved, the rapid acceleration performance of the vehicle can be improved, and the user can determine whether rapid acceleration is performed or not according to the state signal to improve the user experience.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to an acceleration control method, system and vehicle. Background technique [0002] With the improvement of people's awareness of energy security and environmental protection, pure electric vehicles have become the development trend of the vehicle industry. Pure electric vehicles have the advantages of no pollution, low noise, simple structure, and convenient maintenance. [0003] For pure electric vehicles, the acceleration performance is the main index to measure the performance of the vehicle and the safety of overtaking. For existing pure electric vehicles, the rapid acceleration performance is generally improved by developing a new electric drive system, and the cost is relatively high. Contents of the invention [0004] In view of this, the present invention aims to provide an acceleration control method, system and vehicle to solve the problem of high cost in th...
