传统的车辆能耗的评分方法是通过将车辆中驾驶员的驾驶行为数据,以及车辆所行驶的道路的道路数据,输入能耗评分模型,以计算预设行程内车辆能耗的评分。其中,驾驶 行为数据包括预设时间段内驾驶员加减速的频繁程度,预设时间段内驾驶员加减速的剧烈程度等。道路数据包括道路等级以及道路不平程度等。The traditional scoring method of vehicle energy consumption is to input the driving behavior data of the driver in the vehicle and the road data of the road the vehicle travels into the energy consumption scoring model to calculate the vehicle energy consumption score within the preset trip. The driving behavior data includes the frequency of the driver's acceleration and deceleration within the preset time period, the severity of the driver's acceleration and deceleration within the preset time period, and the like. Road data includes road grade and road unevenness.
然而,随着车辆电子化程度越来越高,影响车辆能耗的因素也越来越多,上述传统的车辆能耗的评分方法仅基于驾驶行为数据以及道路数据进行,使得计算出的车辆能耗的评分并不准确。However, with the increasing degree of vehicle electronics, there are more and more factors affecting vehicle energy consumption. The above-mentioned traditional vehicle energy consumption scoring method is only based on driving behavior data and road data, so that the calculated vehicle energy consumption The consumption rating is not accurate.
为了避免上述问题,本申请实施例提供了一种新的车辆能耗的评分方法,即基于目前车辆中影响车辆能耗的因素,重新调整了能耗影响因子。在本申请实施例中,上述能耗影响因子主要分为五类,下文先对上述五类能耗影响因子进行介绍。In order to avoid the above problem, an embodiment of the present application provides a new scoring method for vehicle energy consumption, that is, based on the factors affecting vehicle energy consumption in the current vehicle, the energy consumption influencing factor is readjusted. In the embodiments of the present application, the above-mentioned energy consumption influencing factors are mainly divided into five categories, and the above-mentioned five types of energy consumption influencing factors are introduced first.
第一类能耗影响因子x
1:环境影响因子,用于指示预设行程内车辆所在的行驶环境对车辆能耗的影响程度。环境影响因子主要包括外温非适宜程度影响参数、天气影响参数、昼夜影响参数或风速影响参数中的一种或多种因子。下文针对上述4种环境影响参数分别进行介绍。
The first type of energy consumption influence factor x 1 : an environmental influence factor, which is used to indicate the degree of influence on the energy consumption of the vehicle by the driving environment where the vehicle is located within the preset trip. The environmental influence factors mainly include one or more of the influence parameters of the unsuitability of the external temperature, the weather influence parameters, the day and night influence parameters or the wind speed influence parameters. The following describes the above four environmental impact parameters respectively.
1)外温非适宜程度影响参数,用于指示预设行程内位于预设适宜温度区间之外的环境温度对车辆中部件的工作状态的影响程度。1) The influence parameter of the unsuitable degree of external temperature, which is used to indicate the influence degree of the ambient temperature outside the preset suitable temperature range within the preset travel on the working state of the components in the vehicle.
通常,外温直接影响是否对车辆中的部件进行冷却或者加热。例如,当外温过低时,为了给车辆中的部件提供合适的工作温度,车辆需要消耗一定能源为车辆中的部件进行升温。又例如,当外温过高时,为了给车辆中的部件提供合适的工作温度,车辆需要消耗一定能源为车辆中的部件进行降温。因此,外温非适宜程度影响参数对车辆的能耗的影响较为重要。Typically, the outside temperature directly affects whether components in the vehicle are cooled or heated. For example, when the external temperature is too low, in order to provide a suitable working temperature for the components in the vehicle, the vehicle needs to consume a certain amount of energy to heat up the components in the vehicle. For another example, when the external temperature is too high, in order to provide a suitable working temperature for the components in the vehicle, the vehicle needs to consume a certain amount of energy to cool the components in the vehicle. Therefore, the influence parameters of the unsuitable degree of external temperature on the energy consumption of the vehicle are more important.
申请人发现外温非适宜程度影响参数对车辆的能耗的影响可以视为线性的,则外温非适宜程度影响参数可以通过对外温非适宜数据进行线性归一化处理得到,其中,外温非适宜程度数据包括预设行程内车辆外部环境温度。The applicant found that the influence of the influence parameters of the unsuitability of the outside temperature on the energy consumption of the vehicle can be regarded as linear, and the influence parameters of the unsuitability of the outside temperature can be obtained by linearly normalizing the unsuitability data of the outside temperature. The unsuitability data includes the ambient temperature outside the vehicle within the preset trip.
假设T
1表示车辆中部件的适宜工作温度区间的下限,T
2表示上述部件的适宜工作温度区间的上限,如此,该部件对应的适宜工作温度区间为[T
1,T
2]。则外温非适宜程度影响参数x
11可以通过公式
确定,且
其中,Δt
max为预设值,n表示上述预设行程内的采样点的总数,i表示上述预设行程内的第i个采样点,t
i表示在所述第i个采样点采集的所述车辆外部环境温度,i=1,2,…,n,。
Suppose T 1 represents the lower limit of the suitable working temperature range of the components in the vehicle, and T 2 represents the upper limit of the suitable working temperature range of the above-mentioned components. Thus, the suitable working temperature range corresponding to the component is [T 1 , T 2 ]. Then the influence parameter x 11 of the unsuitable degree of external temperature can be calculated by the formula sure, and Wherein, Δt max is a preset value, n represents the total number of sampling points in the preset stroke, i represents the ith sampling point in the preset stroke, and t i represents all the sampling points collected at the ith sampling point. the external ambient temperature of the vehicle, i=1,2,...,n,.
需要说明的是,Δt
max可以在汽车出厂时由厂商为车辆配置。进一步地,厂商可以基于车辆常规行驶环境设定。例如,车辆的常规行驶环境为中国,上述Δt
max可以设定为50摄氏度。
It should be noted that Δt max can be configured for the vehicle by the manufacturer when the vehicle leaves the factory. Further, the manufacturer can set it based on the normal driving environment of the vehicle. For example, the normal driving environment of the vehicle is China, and the above Δt max may be set to 50 degrees Celsius.
还需要说明的是,上述车辆中部件可以指车辆中比较重要的部件,例如发动机等。上述车辆中部件也可以指车辆中的多个或全部部件,本申请实施例对此不作限定。It should also be noted that the above-mentioned components in a vehicle may refer to relatively important components in a vehicle, such as an engine and the like. The above-mentioned components in a vehicle may also refer to multiple or all components in a vehicle, which are not limited in the embodiments of the present application.
若上述车辆中的部件指车辆中的多个或全部部件时,为了提高计算能耗评分的准确性,不同的部件对应的适宜外温区间可以不同。当然,如果为了简化适宜外温区间的配置过程,可以为多个或全部部件配置相同的适宜外温区间,本申请实施例对此不作限定。If the above-mentioned components in the vehicle refer to multiple or all of the components in the vehicle, in order to improve the accuracy of calculating the energy consumption score, the appropriate external temperature ranges corresponding to different components may be different. Of course, in order to simplify the configuration process of the suitable external temperature range, the same suitable external temperature range may be configured for multiple or all components, which is not limited in this embodiment of the present application.
2)天气影响参数,用于指示预设行程内天气对车辆的工作状态的影响程度。2) The weather influence parameter is used to indicate the influence degree of the weather in the preset trip on the working state of the vehicle.
一方面,雨雪天气下车辆中需要启动的部件较多,例如,雨刮器、后窗加热装置等装置。启动的部件越多,会增加车辆的能耗。另一方面,雨雪天气下,路面湿滑导致道路的 附着力下降,车辆的行驶速度较缓慢,导致车辆需要较大的驱动力,也会增加车辆的能耗。因此,天气影响参数对车辆的能耗的影响较为重要。On the one hand, there are many components in a vehicle that need to be activated in rainy and snowy weather, such as wipers, rear window heating devices and other devices. The more components that are activated, the higher the energy consumption of the vehicle. On the other hand, in rainy and snowy weather, the road surface is slippery and the adhesion of the road is reduced, and the driving speed of the vehicle is slow, which causes the vehicle to require a large driving force and also increases the energy consumption of the vehicle. Therefore, the influence of weather influence parameters on the energy consumption of vehicles is more important.
申请人发现天气影响参数对车辆的能耗的影响可以视为线性的,则天气影响参数可以通过对车辆的天气数据进行线性归一化处理得到,其中天气影响数据包括预设行程内车辆的雨刮器所工作的一个或多个档位、以及预设行程内雨刮器处于每个档位的工作时长。The applicant found that the influence of the weather influence parameters on the energy consumption of the vehicle can be regarded as linear, and the weather influence parameters can be obtained by performing linear normalization on the weather data of the vehicle, wherein the weather influence data includes the wipers of the vehicle within the preset itinerary. The working gear or gears, and the working time of the wiper in each gear within the preset stroke.
