The driving module may be a component such as a motor for driving the vehicle to accelerate.
For example, when the acceleration request of the user is a rapid acceleration request, the temperature of the driving module may be lowered as low as possible before the user rapidly accelerates the vehicle, so as to achieve the best rapid acceleration performance.
In practical applications, the vehicle may be provided with an acceleration button, an acceleration handle, a touch panel, an accelerator opening detector, and the like to obtain an acceleration request of a user. The embodiment of the present invention is not limited thereto.
Specifically, the rapid acceleration of the vehicle may be a change in the traveling speed of the vehicle reaching a preset value in a short time. The rapid acceleration capability of the vehicle may be used to evaluate the performance of the vehicle for rapid acceleration. While non-rapid acceleration of the vehicle may include, but is not limited to: economy mode, sport mode, and terrain-specific mode, among others.
Step 102: and controlling a thermal management system to execute forced cooling operation of a preset time on a driving module under the condition that the acceleration request is the emergency acceleration request.
In the embodiment of the invention, when the acceleration request of the user is judged to be the rapid acceleration request, the forced refrigeration operation is carried out on the vehicle for the preset time length, specifically, the forced refrigeration is carried out on the driving module of the vehicle for a certain time length, so that the driving module of the vehicle can dissipate heat as soon as possible, and the best performance is achieved after the preset time when the rapid acceleration is carried out.
In practical applications, the step of performing the forced cooling operation includes: a heat management system in the vehicle controls heat dissipation elements such as a radiator, a water pump and an air conditioner to dissipate heat of the driving module for preset time.
Referring to fig. 2, a schematic structural diagram of a heat dissipation circuit of a driving module according to an embodiment of the present invention is shown, and as shown in fig. 2, the heat dissipation circuit of the driving module includes: drive module 10, radiator 20, water pump 30, air conditioner 40, first switch K1 and second switch K2, wherein, drive module 10 radiator 20 water pump 30 with air conditioner 40 is end to end in proper order, drive module 10 with be provided with between the water pump 30 first switch K1, drive module 10 with be provided with between the air conditioner 40 second switch K2.
Referring to fig. 3, a flowchart illustrating steps of another acceleration control method according to an embodiment of the present invention is shown. As shown in fig. 3, when the acceleration request of the user is a rapid acceleration request, the forced cooling mode is entered, K1 is turned off, K2 is turned on, and the radiator 20, the water pump 30 and the air conditioner 40 together radiate heat to the driving module 10; when the acceleration request of the user is an emergency acceleration request, the normal heat dissipation mode is entered, the K1 is closed, the K2 is opened, and only the radiator 20 and the water pump 30 dissipate heat of the driving module 10.
In the forced cooling operation, the air conditioner 40 is used to help the driving module 10 to dissipate heat, so as to improve the heat dissipation capability of the driving module 10, and to achieve the best heat dissipation effect of the driving module 10 in a short time, since the driving capability of the driving module 10 is affected by the heat dissipation capability thereof. If the temperature of the driving module 10 can be rapidly reduced within the preset time, the driving capability of the driving module 10 can be improved, and the rapid acceleration performance of the vehicle can be improved.
In the embodiment of the present invention, when the acceleration request is a rapid acceleration request, the step of controlling the thermal management system to perform a forced cooling operation on the driving module 10 for a preset time includes: acquiring the current working temperature of the driving module 10, and determining the target working temperature of the driving module 10, wherein the target working temperature can be determined according to the current environment temperature of the vehicle and the performance of the driving module 10; secondly, determining the heat dissipation amount required by the driving module to be reduced from the current working temperature to the target working temperature within the preset time according to the preset time required by the forced refrigeration, the current working temperature and the target working temperature, and determining the third power required to be output by the heat management system according to the heat dissipation amount; and finally, controlling the thermal management system to perform heat dissipation on the driving module 10 for a preset time at the third power.
Specifically, the step of determining the target working temperature of the driving module comprises the following steps of; according to the time required by the sharp acceleration working condition of the vehicle, the driving force required to be output by the driving module 10 for sharp acceleration is determined, then the torque external characteristic value required by the driving module is determined according to the driving force, and finally the target working temperature can be determined according to the torque external characteristic value.
In practical applications, the specific heat dissipation powers of the radiator 20, the water pump 30 and the air conditioner 40 may be set according to practical situations. In the embodiment of the present invention, the air conditioner 40 may perform the following different operations for dissipating heat of the driving module 10 within a preset time:
in the first case, the air conditioner 40 is controlled to dissipate heat of the driving module 10 with a first power, where the first power refers to the maximum output power of the air conditioner 40, that is, all the output power of the air conditioner 40 is used to dissipate heat of the driving module 10, and at this time, the heat dissipation speed of the driving module 10 is the fastest.
In the second case, while the air conditioner 40 is controlled to radiate heat to the driving module 10 at the first power, the operation instruction of the user to the air conditioner 40 is obtained; and according to an operation instruction of the user on the air conditioner 40, controlling the air conditioner 40 to radiate heat to the driving module 10 with a second power, wherein the second power is smaller than the first power. In practical application, after an operation instruction of the user on the air conditioner 40 is obtained, the power provided by the air conditioner 40 to the driving module 10 for heat dissipation is reduced from the first power to the second power, so that part of the output power of the air conditioner 40 is used for temperature adjustment in the vehicle, and in this case, the heat dissipation speed of the driving module 10 is slower than that in the first case, but the comfort requirement of the user can be met, and the comfort experience of the user is improved.
In this case, the multimedia module in the vehicle may prompt the user that "the air conditioning system is limited in function and the air conditioner may be turned on manually" so that the user may perform corresponding operations as desired. The prompting mode can be voice prompting or multimedia text prompting.
In practical application, the preset time can be determined through different working conditions. For example, the preset time may be determined by subtracting the target operating temperature of the driving module 10, which exerts the driving capability, from the current operating temperature of the driving module 10, and combining the heat dissipation amount of the actual output power of the air conditioner 40. Wherein, the actual output power of the air conditioner 40 may be one of the first power and the second power.
For another example, the preset time may be determined by subtracting the operating temperature of the driving module 10, which exerts the driving capability, from the highest temperature of the driving module 10 in the summer environment, and combining the heat dissipation amount of the actual output power of the air conditioner 40. Wherein, the actual output power of the air conditioner 40 may be one of the first power and the second power. The working temperature can be determined according to the time requirement of the sharp acceleration working condition of the vehicle, the driving force required to be exerted by the driving module is determined, the torque external characteristic value required by the driving module is determined according to the driving force, and the torque external characteristic value is determined. The preset time is determined through the highest temperature in the summer environment, the longest time required for the driving module 10 to reach the preset temperature can be obtained, and therefore sufficient cooling time can be reserved for the vehicle, and the driving module 10 is guaranteed to reach the best driving capability within the preset time.
Step 103: and collecting the temperature of the driving module.
In the embodiment of the invention, under the condition that the acceleration request of the user is determined to be the rapid acceleration request, the forced refrigeration operation is started to be executed, and the time for acquiring the temperature of the driving module can be determined in a manner of counting down the forced refrigeration operation, wherein the counting down time can be preset time which is set manually. After the countdown time is over, which is equivalent to the lapse of the preset time, the temperature of the driving module 10 is collected to determine whether the temperature of the driving module 10 reaches the preset temperature, where the preset temperature may be the optimal temperature when the driving module 10 performs the rapid acceleration driving. In practical applications, the countdown prompt may include, but is not limited to, a voice prompt or a multimedia text prompt.
Specifically, a temperature sensor may be disposed on the driving module 10, and the temperature of the driving module 10 may be acquired by the temperature sensor.
Step 104: and feeding back a sudden acceleration performance state signal of the vehicle according to the temperature.
In this step, it is necessary to evaluate the rapid acceleration performance of the driving module 10 according to the temperature of the driving module 10 collected in step 103, and to feed back a rapid acceleration performance status signal to the user, so as to help the user perform corresponding operations according to the feedback.
For example, the rapid acceleration performance status signal may include: a rapid acceleration performance normal signal and a rapid acceleration performance limited signal; comparing the temperature with a preset temperature, and feeding back the rapid acceleration performance normal signal under the condition that the temperature is lower than or equal to the preset temperature; and feeding back the rapid acceleration performance limiting signal under the condition that the temperature is higher than the preset temperature. The preset temperature may be an optimum temperature when the driving module 10 performs the rapid acceleration operation, or may be a preferred temperature set manually.
In practical application, when the fed back signal is a signal with normal rapid acceleration performance, the user can select rapid acceleration operation on the vehicle, and the vehicle can reach the preset speed of the vehicle in a short time. When the feedback signal is the signal with limited rapid acceleration performance, the user can know that the expected acceleration effect may not be achieved even if the rapid acceleration operation is performed, at this time, the user can also choose not to perform the rapid acceleration operation, and perform a rapid acceleration request again for the vehicle, so that the vehicle performs the forced cooling operation again on the driving module 10, and the steps are repeated until the temperature of the driving module 10 reaches the preset temperature, and the user performs the rapid acceleration operation again under the condition that the vehicle feeds back the signal with normal rapid acceleration performance to the user.
In practical application, the maximum required power of the thermal management system can be determined according to practical conditions. For example, when the current ambient temperature is the highest ambient temperature of the vehicle, determining the highest temperature of the drive module 10 according to the highest ambient temperature and the highest operating temperature of the drive module; determining the heat dissipation amount required by the driving module 10 to reduce from the maximum temperature to the target working temperature within the preset time; and determining the maximum required power of the thermal management system according to the heat dissipation capacity. According to the maximum required power, a performance index of the thermal management system can be determined, and a basis is provided for selection of a heat dissipation element in the thermal management system of the vehicle.
In practical applications, the feedback may be in the form of, but not limited to, voice prompts or multimedia text prompts.
In summary, the control method according to the embodiment of the present invention at least includes the following advantages:
the embodiment of the invention provides an acceleration control method for a vehicle, which comprises the following steps: acquiring an acceleration request of a user, wherein the acceleration request comprises an urgent acceleration request and an urgent acceleration request; and in the case that the acceleration request is a rapid acceleration request, performing forced cooling operation for a preset time so that the temperature of the driving module is rapidly reduced.
