[0057] It should be noted that in the present disclosure, the terms "S101", "S102", etc. in the description and claims and the drawings are used to distinguish steps, and it is not necessarily understood that the method steps are performed in a specific order or sequence. The embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0058] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0059] As described in the background, in a hybrid system, the engine and the battery can simultaneously serve as a heat source for heating the passenger cabin, thereby balancing the engine thermal efficiency and the passenger cabin comfort. However, in the process of heating the cabin of a new energy hybrid vehicle, the engine waste heat cannot be used to heat the cabin preferentially under the premise of meeting the temperature demand of the passenger cabin, which results in a waste of resources.

[0060] Therefore, the present disclosure provides a hybrid vehicle and a cabin heating control method, device and system thereof. In the process of heating the cabin of a new energy hybrid vehicle, the engine waste heat is used to heat the cabin preferentially, which effectively utilizes the engine waste heat and is beneficial to reduce energy consumption and avoid waste of resources.

[0061] Figure 1 is a flowchart of a cabin heating control method according to an exemplary embodiment. Referring to Figure 1 , the cabin heating control method includes the following steps:

[0062] In step S101, a cabin heating request is obtained.

[0063] In step S102, heating parameters of the engine are obtained based on the heating request, the heating parameters including a plurality of sub-parameters affecting the engine to generate heat.

[0064] In step S103, a heating time is determined according to the heating parameters, the heating time being a start time for satisfying a preset heating condition of the engine by using the engine waste heat.

[0065] In step S104, the engine waste heat is started according to the heating time.

[0066] In the above manner, after obtaining the cabin heating request, the present disclosure determines the heating time for starting the engine waste heat heating according to the heating parameters of the engine, and starts the engine waste heat heating according to the heating time, which reasonably uses the engine waste heat to heat the cabin, effectively utilizes the engine waste heat, is beneficial to reduce energy consumption, and avoids waste of resources.

[0067] For the convenience of those skilled in the art to understand, the present disclosure is described in detail below through examples.

[0068] Wherein, because the engine heating parameter includes multiple sub-parameters, when determining the heating time according to the heating parameter, there are multiple cases, such as only one sub-parameter meets the engine waste heat heating condition or multiple heating parameters meet the engine waste heat heating condition, and the determination manner of the heating time is different in different cases.

[0069] In the case that multiple sub-parameters meet the engine waste heat heating condition, the initial heating time corresponding to each sub-parameter meeting the engine waste heat heating condition needs to be determined respectively, the multiple initial heating times are weighted processed to determine the heating time, so as to start the engine waste heat heating according to the heating time.

[0070] In an embodiment, in step S103, determining the heating time according to the heating parameter comprises:

[0071] respectively judging whether each sub-parameter meets the preset engine heating condition;

[0072] In the case that two or more sub-parameters meet the engine waste heat heating condition, determining the initial heating time corresponding to the sub-parameter meeting the engine waste heat heating condition;

[0073] According to the weight corresponding to each initial heating time, the initial heating time is weighted processed to obtain the heating time.

[0074] For example, it is judged whether the engine power, the engine temperature rise rate, the environment temperature, the cabin target outlet temperature, the battery power, the vehicle travel and the power consumption of the electrical device on the vehicle meet the engine waste heat heating condition; in the case that the engine power and the engine temperature rise rate meet the engine waste heat heating condition at the same time, two initial heating times corresponding to the engine power and the engine temperature rise rate respectively are obtained; according to the weight corresponding to the two initial heating times, the two initial heating times are weighted processed to obtain the heating time.

[0075] By weighting processing the multiple initial times to obtain the heating time, the engine waste heat heating can be started more reasonably, and resource waste is avoided.

[0076] In the case that one sub-parameter meets the engine waste heat heating condition, the initial heating time corresponding to the sub-parameter can be directly taken as the heating time, so as to start the engine waste heat heating according to the heating time.

[0077] In an embodiment, in step S103, determining the heating time according to the heating parameter comprises:

[0078] respectively determine whether each sub-parameter meets the engine preset heating condition;

[0079] In the case that only one sub-parameter meets the engine waste heat heating condition, determine the initial heating time corresponding to the sub-parameter, and determine the initial heating time as the heating time.

[0080] For example, respectively determine whether the engine power, the engine temperature rise rate, the ambient temperature, the cabin target air outlet temperature, the battery power, the vehicle travel distance, and the power consumption of the electrical device on the vehicle meet the engine waste heat heating condition; in the case that only the engine power meets the engine waste heat heating condition, obtain the initial heating time corresponding to the engine power, and determine the initial heating time as the heating time.

[0081] Each sub-parameter is in proportional relationship with the engine waste heat amount, and the engine waste heat amount can be determined according to the proportional relationship between each sub-parameter and the engine waste heat amount, and the time corresponding to the engine waste heat amount is determined as the heating time.

[0082] In an embodiment, determining the heating time according to the heating parameter comprises:

[0083] Determining the engine waste heat amount according to the heating parameter;

[0086] In an embodiment, the engine power, the engine temperature rise rate, the ambient temperature, the vehicle travel distance, and the power consumption of the electrical device on the vehicle are in direct proportion to the engine waste heat amount;

[0087] The cabin target air outlet temperature and the battery power are in inverse proportion to the engine waste heat amount.

[0088] For example, refer to Figure 2 Under the same working condition, the engine power 1 is greater than the engine power 2, the heating time of starting the engine waste heat heating at the engine power 1 is earlier than the heating time of starting the engine waste heat heating at the engine power 2, and the resource utilization rate at the engine power 1 is better than the resource utilization rate at the engine power 2, that is, under the same working condition, the greater the engine power, the earlier the heating time of starting the engine waste heat heating, and vice versa, the smaller the engine power, the later the heating time of starting the engine waste heat heating.

[0089] For example, refer to Figure 3, the engine temperature rise 1 is greater than the engine temperature rise 2, the heating time of starting the engine waste heat heating at the engine temperature rise 1 is earlier than the heating time of starting the engine waste heat heating at the engine temperature rise 1, the resource utilization rate at the engine temperature rise 1 is superior to the resource utilization rate at the engine temperature rise 2, that is, the faster the engine temperature rise rate, the earlier the heating time of starting the engine waste heat heating, and vice versa, the slower the engine temperature rise rate, the later the heating time of starting the engine waste heat heating;

[0090] With reference to Figure 4 , the outside temperature 1 is greater than the outside temperature 2, the outside temperature 2 is greater than the outside temperature 3, the heating time of starting the engine waste heat heating at the outside temperature 1 is earlier than the heating time of starting the engine waste heat heating at the outside temperature 2, the heating time of starting the engine waste heat heating at the outside temperature 2 is earlier than the heating time of starting the engine waste heat heating at the outside temperature 3, the resource utilization rate at the outside temperature 1 is superior to the resource utilization rate at the outside temperature 2 and the outside temperature 3, the resource utilization rate at the outside temperature 2 is superior to the resource utilization rate at the outside temperature 3, that is, the higher the outside temperature, the earlier the heating time of starting the engine waste heat heating, and vice versa, the lower the outside temperature, the later the heating time of starting the engine waste heat heating;

[0091] With reference to Figure 5 , the target outlet temperature 3 of the cabin is greater than the target outlet temperature 2, the target outlet temperature 2 is greater than the target outlet temperature 1, the heating time of starting the engine waste heat heating at the target outlet temperature 3 is earlier than the heating time of starting the engine waste heat heating at the target outlet temperature 2, the heating time of starting the engine waste heat heating at the target outlet temperature 2 is earlier than the heating time of starting the engine waste heat heating at the target outlet temperature 1, the resource utilization rate at the target outlet temperature 3 is superior to the resource utilization rate at the target outlet temperature 2 and the target outlet temperature 1, the resource utilization rate at the target outlet temperature 2 is superior to the resource utilization rate at the target outlet temperature 1, that is, the lower the target outlet temperature, the earlier the heating time of starting the engine waste heat heating, and vice versa, the higher the target outlet temperature, the later the heating time of starting the engine waste heat heating.

[0092] In an embodiment, the method further comprises: according to the preset priority of the engine power, the engine temperature rise rate, the environment temperature, the target outlet temperature of the cabin, the battery power, the vehicle travel distance and the power consumption of the electrical device on the vehicle, the weight corresponding to the initial heating time corresponding to the engine power, the engine temperature rise rate, the environment temperature, the target outlet temperature of the cabin, the battery power, the vehicle travel distance and the power consumption of the electrical device on the vehicle is calibrated, wherein the preset priority is proportional to the weight.

[0093] The preset of each sub-parameter priority is related to the influence of each sub-parameter on engine waste heat heating, for example, the priority of engine temperature rise rate is greater than the priority of engine power, the priority of engine power is greater than the priority of external temperature and the priority of cabin target air outlet temperature, and the relationship between the priority of external temperature and the priority of cabin target air outlet temperature is determined according to the actual working condition of engine waste heat heating, which is not limited in the present disclosure.

[0094] The heating time is flexibly determined according to the judgment result of whether each sub-parameter meets the engine waste heat heating condition, so that the engine waste heat heating is started according to the heating time, and the more optimized use of resources is realized, and resource waste is avoided.

[0095] In an embodiment, the engine preset heating condition includes:

[0096] whether the engine power is greater than a preset power; and / or,

[0097] whether the engine temperature rise rate is greater than a preset temperature rise rate; and / or,

[0098] whether the environment temperature is greater than a preset environment temperature; and / or,

[0099] whether the cabin target air outlet temperature is greater than a preset air outlet temperature; and / or,

[0100] whether the battery power is less than a first power threshold; and / or,

[0101] whether the vehicle travel distance is greater than a preset travel distance; and / or,

[0102] whether the power consumption of the electrical device is greater than a second power threshold.

[0103] The preset power, the preset temperature rise rate, the preset environment temperature, the preset air outlet temperature, the first power threshold, the preset travel distance and the second power threshold can be preset according to the corresponding relationship between the engine waste heat heating process and the waste heat heating amount, which is not limited in the present disclosure.

[0104] By taking the state of engine power, engine temperature rise rate, environment temperature, cabin target air outlet temperature, battery power, vehicle travel distance and power consumption of vehicle electrical device as engine waste heat heating condition, the more optimized use of energy is realized when the cabin temperature requirement is guaranteed and the engine works in the optimal state, and the vehicle energy consumption is reduced.

[0105] The sub-parameters in the present disclosure are not limited to engine power, engine temperature rise rate, ambient temperature, state of cabin target air outlet temperature, battery power, vehicle travel, and power consumption of vehicle electrical devices, but can also involve other parameters related to starting engine waste heat heating during vehicle travel; The engine preset heating condition can also be determined by combining the judgment results of two parameters, such as battery power and vehicle travel, and the engine preset heating condition is met when the battery power is less than the first power threshold and the vehicle travel is greater than the vehicle travel; Or combine the battery power and the power consumption of the vehicle electrical device to judge, and the engine preset heating condition is met when the battery power is less than the first power threshold and the power consumption of the vehicle electrical device is greater than the second power threshold.
