技术领域Technical field

背景技术Background technique

例如,当电池电量比较低,此时车的速度就会达不到较高值,因为电池功率受限,如果此时车辆行驶在高速路上,高速路有些地段设置最低行驶车速如60km/h,此时车辆动力受限制,达不到交通法规的车速最小值,会导致被电子眼等监控设施拍照,进行罚款与扣分处理,但是这不是驾驶员人为因素。For example, when the battery power is relatively low, the car's speed will not reach the high value because the battery power is limited. If the vehicle is driving on the highway at this time, some sections of the highway have a minimum driving speed such as 60km/h. At this time, the power of the vehicle is limited and the vehicle speed cannot reach the minimum speed required by traffic regulations, which will result in being photographed by monitoring facilities such as electronic eyes and subject to fines and deductions. However, this is not a human factor on the part of the driver.

然而,交通法规设施无法识别是车辆原因还是人为因素导致驾驶车辆没有按照交通法规进行行驶,驾驶员也不能够实时计算出自己的车辆的动力性是否满足交通法规的车速最低值。However, traffic regulations facilities cannot identify whether the vehicle or human factors cause the vehicle to fail to drive in accordance with traffic regulations, and the driver cannot calculate in real time whether the power of his vehicle meets the minimum speed of the traffic regulations.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and cannot be understood as limiting the present invention.

下面参考图1-图2描述根据本发明实施例的电动车辆功率受限控制方法。The following describes an electric vehicle power limited control method according to an embodiment of the present invention with reference to FIGS. 1-2 .

根据本发明实施例的电动车辆功率受限控制方法,包括:An electric vehicle power limited control method according to an embodiment of the present invention includes:

S11,在电动车辆1000行驶在低速受限的道路上时,获取当前道路的最低限速,并获取当前道路的坡度信息;S11, when the electric vehicle 1000 is driving on a low-speed restricted road, obtain the minimum speed limit of the current road and obtain the slope information of the current road;

S12,获取动力电池的当前最大放电功率,并获取电机的当前最大驱动功率,以及获取电动车辆1000的高压附件的当前消耗功率;S12, obtain the current maximum discharge power of the power battery, obtain the current maximum driving power of the motor, and obtain the current power consumption of the high-voltage accessories of the electric vehicle 1000;

S13,根据当前道路的坡度信息、动力电池的当前最大放电功率、电机的当前最大驱动功率以及高压附件的当前消耗功率计算电动车辆1000的当前最高运行速度;S13, calculate the current maximum operating speed of the electric vehicle 1000 based on the current slope information of the road, the current maximum discharge power of the power battery, the current maximum driving power of the motor, and the current power consumption of the high-voltage accessories;

S14,在电动车辆1000的当前最高运行速度小于当前道路的最低限速时,控制车外提示装置500发出低速行驶提示信息。S14: When the current maximum operating speed of the electric vehicle 1000 is less than the minimum speed limit of the current road, control the vehicle exterior prompt device 500 to send out low-speed driving prompt information.

可以理解的是,本发明提供一种电动车辆功率受限控制方法,主要解决了非人为因素导致车辆不满足城市快速路或是高速要求的最低行驶车速而导致罚款扣分的难题。It can be understood that the present invention provides a power limited control method for electric vehicles, which mainly solves the problem of non-human factors causing the vehicle to fail to meet the minimum driving speed required by urban expressways or highways, resulting in fines and deductions.

例如,电动车辆1000可以智能计算出在低速受限道路上的车辆能够达到的最高运行车速,当车辆计算车辆的最高车速值小于当前道路的最低限速即不满足交通法规时,车外提示装置500发出低速行驶提示信息,表明当前形式状况是车辆驱动能力所造成的,这样交通电子眼等交通检测装置2000可以利用车外提示装置500对车辆进行判罚,既可以避免驾驶员非人为因素导致违反交通法规的尴尬,可以避免驾驶员个人的驾照扣分与罚款,也可以便于交通部门获取车辆的真实状态,对涉事车辆进行合理处理。For example, the electric vehicle 1000 can intelligently calculate the maximum operating speed that the vehicle can reach on a low-speed restricted road. When the vehicle calculates that the maximum speed of the vehicle is less than the minimum speed limit of the current road, that is, it does not meet the traffic regulations, the external prompt device 500 sends out a low-speed driving prompt message, indicating that the current situation is caused by the vehicle's driving ability. In this way, traffic detection devices 2000 such as traffic electronic eyes can use the external prompt device 500 to penalize the vehicle, which can avoid traffic violations caused by the driver's non-human factors. The embarrassment of regulations can avoid the driver's personal driver's license points and fines, and also facilitate the transportation department to obtain the true status of the vehicle and reasonably deal with the vehicle involved.

另外,车外提示装置在在电动车辆1000的当前最高运行速度小于当前道路的最低限速时发出低速行驶提示信息,也可以避免驾驶员私自点亮警示灯,有便于交通管制。In addition, the off-vehicle reminder device sends out a low-speed driving reminder message when the current maximum operating speed of the electric vehicle 1000 is less than the minimum speed limit of the current road, which can also prevent the driver from lighting the warning light privately and facilitate traffic control.

由此,解决了目前市面上的电动车的非人为因素导致车速不符合交通法规要求的问题;车辆不规范的驾驶行为是人为因素还是车辆因素,更加合理和安全。This solves the problem of non-human factors in electric vehicles currently on the market that cause the vehicle speed to fail to meet the requirements of traffic regulations; it is more reasonable and safe whether the vehicle's irregular driving behavior is a human factor or a vehicle factor.

根据本发明实施例的电动车辆功率受限控制方法,通过当前道路的坡度信息、动力电池的当前最大放电功率、电机的当前最大驱动功率以及高压附件的当前消耗功率计算电动车辆1000的当前最高运行速度,并在电动车辆1000的当前最高运行速度小于当前道路的最低限速时,控制车外提示装置500发出低速行驶提示信息。由此便于交通部门获取车辆的真实状态,既可以避免驾驶员非人为因素导致个人的驾照扣分与罚款,也可以使得交通部门对涉事车辆进行合理处理,从而可以提升交通管制的便利性和合理性,节约时间成本。According to the electric vehicle power limited control method according to the embodiment of the present invention, the current maximum operation of the electric vehicle 1000 is calculated through the slope information of the current road, the current maximum discharge power of the power battery, the current maximum driving power of the motor, and the current power consumption of high-voltage accessories. speed, and when the current maximum operating speed of the electric vehicle 1000 is less than the minimum speed limit of the current road, the vehicle exterior prompt device 500 is controlled to issue a low-speed driving prompt message. This makes it easier for the transportation department to obtain the true status of the vehicle, which can not only avoid the deduction of points and fines on the individual's driver's license caused by the driver's non-human factors, but also enable the transportation department to reasonably deal with the vehicles involved, thereby improving the convenience and convenience of traffic control. Rationality, saving time and cost.

在一些实施例中,根据当前道路的坡度信息、动力电池的当前最大放电功率、电机的当前最大驱动功率以及高压附件的当前消耗功率计算电动车辆1000的当前最高运行速度,包括:根据动力电池的当前最大放电功率和高压附件的当前消耗功率计算可用功率,并根据可用功率和电机的当前最大驱动功率确定实际驱动可用功率;根据实际驱动可用功率和当前道路的坡度信息计算电动车辆1000的当前最高运行速度。由此,通过动力电池的当前最大放电功率和高压附件的当前消耗功率计算可用功率,能够计算出整车从电池层面来说,可以用来驱动的功率。通过可用功率和电机的当前最大驱动功率确定实际驱动可用功率,可以判定出整车综合电池和电机系统后,整车实际可以用来驱动的功率值。由此。可以使得计算出的最高运行速度更加真实、准确。In some embodiments, calculating the current maximum operating speed of the electric vehicle 1000 based on the current slope information of the road, the current maximum discharge power of the power battery, the current maximum driving power of the motor, and the current power consumption of the high-voltage accessories includes: The current maximum discharge power and the current power consumption of high-voltage accessories are used to calculate the available power, and the actual driving available power is determined based on the available power and the current maximum driving power of the motor; the current maximum driving power of the electric vehicle 1000 is calculated based on the actual driving available power and the slope information of the current road. Running speed. Therefore, by calculating the available power through the current maximum discharge power of the power battery and the current power consumption of high-voltage accessories, the power that can be used to drive the vehicle from the battery level can be calculated. By determining the actual driving power available by the available power and the current maximum driving power of the motor, the actual power value that can be used to drive the vehicle can be determined after integrating the battery and motor systems of the vehicle. thus. This can make the calculated maximum operating speed more realistic and accurate.

具体地,根据以下公式计算电动车辆1000的当前最高运行速度:Specifically, the current maximum operating speed of the electric vehicle 1000 is calculated according to the following formula:

P驱动可用=[m*g*f*cos(a)+m*g*sin(a)+Cd*A*Vmax*Vmax/21.15]*Vmax,P driver available =[m*g*f*cos(a)+m*g*sin(a)+Cd*A*Vmax*Vmax/21.15]*Vmax,

其中,P驱动可用为实际驱动可用功率,m电动车辆1000的整车满载质量值,g为9.8,Cd为电动车辆1000的空气阻力系数,a为当前道路的坡度,A为电动车辆1000的迎风面积,f为滚动阻力系数,Vmax为电动车辆1000的当前最高运行速度。由此,可以求出当前状态下车辆能够达到的最高车速值。Among them, P drive available is the actual driving power available, m is the full vehicle mass value of the electric vehicle 1000, g is 9.8, Cd is the air resistance coefficient of the electric vehicle 1000, a is the slope of the current road, and A is the windward direction of the electric vehicle 1000 area, f is the rolling resistance coefficient, and Vmax is the current maximum operating speed of the electric vehicle 1000. From this, the maximum speed that the vehicle can reach in the current state can be found.

需要说明的是,车辆在量产前都会进行风洞试验,滚动阻力系数的取值有多种方法,可以是根据车速变化的数值,也可以取一个固定值,车辆在出厂前都会进行测试。It should be noted that vehicles will undergo wind tunnel testing before mass production.

Vehicles will be tested before leaving the factory.

在一些可选的实施例中,根据可用功率和电机的当前最大驱动功率确定实际驱动可用功率,包括:对可用功率和电机的当前最大驱动功率进行取小值计算以确定实际驱动可用功率。可以理解的是,有时候电池输出驱动功率足够,由于电机过热或是电机系统自身故障原因,电机系统也会降低功率输出,所以通过对可用功率和电机的当前最大驱动功率进行取小值计算以确定实际驱动可用功率,可以更加真实、准确地得到用来驱动的功率值。In some optional embodiments, determining the actual driving available power based on the available power and the current maximum driving power of the motor includes: performing a minimum calculation of the available power and the current maximum driving power of the motor to determine the actual driving available power. It is understandable that sometimes the battery output driving power is sufficient, but the motor system will also reduce the power output due to motor overheating or motor system failure. Therefore, the available power and the current maximum driving power of the motor are calculated by taking the smaller value. Determining the actual power available for driving can provide a more realistic and accurate power value for driving.

在一些实施例中,获取当前道路的最低限速,包括:通过ADAS系统与导航系统进行信息交互以获取当前道路的最低限速;或者通过车载摄像头采集路边限速交通标志信息以获取当前道路的最低限速。由此,可以实时地获取当前道路的最低限速,并且也能够得到真实、可靠的最低车速要求值。In some embodiments, obtaining the minimum speed limit of the current road includes: performing information interaction with the navigation system through the ADAS system to obtain the minimum speed limit of the current road; or collecting roadside speed limit traffic sign information through a vehicle-mounted camera to obtain the current road the minimum speed limit.

As a result, the traffic department can easily obtain the true status of the vehicle, and can also enable the traffic management platform to record information in real time, allowing the transportation department to reasonably handle the vehicles involved, thereby improving the convenience and rationality of traffic control and saving time and costs. .
