技术领域technical field
本申请涉及车辆控制技术领域,尤其涉及一种车辆驾驶控制方法、装置和控制设备。The present application relates to the technical field of vehicle control, in particular to a vehicle driving control method, device and control equipment.
背景技术Background technique
随着经济水平的飞速发展,汽车已进入千家万户,逐渐成为每个家庭的生活必需品。汽车在行驶过程中,有时轮胎会出现问题,如爆胎,此时,用户可以将随车携带的备胎替换到汽车上,以继续行驶。With the rapid development of the economic level, cars have entered thousands of households and gradually become the necessities of life for every family. When the car is running, sometimes the tires have problems, such as a blowout. At this time, the user can replace the spare tire carried with the car on the car to continue driving.
目前,市面上的备胎可以分为全尺寸备胎、非全尺寸备胎以及零压备胎。全尺寸备胎,是指与原汽车轮胎规格完全相同的备胎,这种类型的备胎是可以“转正”的,即替换后可一直使用,直至其出现问题为止。非全尺寸备胎,是指比原汽车轮胎的轮胎直径略小、宽度较窄的备胎,这种类型的备胎只能作为应急车胎,不能长时间使用,且行驶最高时速不能超过80km/h。在汽车摆脱困境后,用户需要及时将备胎更换为正常轮胎。零压备胎,是指直接隐藏在汽车轮胎上的备胎,其在遭到刺扎后,不会漏气或者漏气非常缓慢,能够保证汽车继续行驶,但是行驶最高时速不能超过80km/h。At present, spare tires on the market can be divided into full-size spare tires, non-full-size spare tires and zero pressure spare tires. A full-size spare tire refers to a spare tire with exactly the same specifications as the original car tire. This type of spare tire can be "reverted", that is, it can be used until it has a problem. A non-full-size spare tire refers to a spare tire with a slightly smaller diameter and narrower width than the original car tire. This type of spare tire can only be used as an emergency tire and cannot be used for a long time, and the maximum speed cannot exceed 80km/h h. After the car gets out of trouble, the user needs to replace the spare tire with a normal tire in time. Zero-pressure spare tire refers to the spare tire directly hidden on the car tire. After being punctured, it will not leak air or leak air very slowly, which can ensure that the car can continue to drive, but the maximum speed cannot exceed 80km/h .
然而,对于非全尺寸备胎和零压备胎,当其投入使用后,由于其与原汽车轮胎存在尺寸差异,有时会出现诸如超过备胎限制速度、汽车零件磨损加快等问题,降低了汽车的安全性。However, for non-full-size spare tires and zero-pressure spare tires, when they are put into use, due to the size difference between them and the original car tires, sometimes there will be problems such as exceeding the speed limit of the spare tire and accelerating the wear and tear of car parts, which will reduce the quality of the car. security.

本申请的实施方式Embodiment of this application
以下描述中,为了说明而不是为了限定,提出了诸如特定***结构、技术之类的具体细节,以便透彻理解本申请实施例。然而,本领域的技术人员应当清楚,在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中,省略对众所周知的***、装置、电路以及方法的详细说明,以免不必要的细节妨碍本申请的描述。In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图通过具体实施例来进行说明。In order to make the purpose, technical solution and advantages of the present application clearer, specific embodiments will be described below in conjunction with the accompanying drawings.
如背景技术所描述的,市面上的备胎可以分为全尺寸备胎、非全尺寸备胎以及零压备胎。对于非全尺寸备胎和零压备胎,当其投入使用后,车速要限制在80km/h以下,有些用户并不清楚或者忘记了此类备胎的使用要求,而该使用要求只是在备胎胎面上通过业内术语进行提示,并不显眼,且现有车辆的控制逻辑也没有针对备胎更换的相应提示,如此,用户在驾驶更换有非全尺寸备胎或零压备胎的车辆时,很容易出现车速超过备胎限制速度的现象,降低了车辆的安全性。As described in the background art, spare tires on the market can be classified into full-size spare tires, non-full-size spare tires and zero-pressure spare tires. For non-full-size spare tires and zero-pressure spare tires, when they are put into use, the vehicle speed must be limited to less than 80km/h. The tire tread is prompted by industry terms, which is not conspicuous, and the control logic of the existing vehicle does not have a corresponding reminder for the replacement of the spare tire. In this way, the user is driving a vehicle with a non-full-size spare tire or a zero-pressure spare tire. When driving, it is easy to appear that the speed of the vehicle exceeds the speed limit of the spare tire, which reduces the safety of the vehicle.
此外,由于非全尺寸备胎和零压备胎的尺寸,与原车辆轮胎存在尺寸差异,导致在车辆行驶过程中,一些车辆零件将工作在非正常工况,例如四驱车辆的摩擦组器件,如此将加快车辆零件的磨损程度,甚至出现损坏现象,也降低了车辆的安全性。In addition, due to the size difference between the non-full-size spare tire and the zero-pressure spare tire and the original vehicle tire, some vehicle parts will work in abnormal working conditions during the driving of the vehicle, such as the friction components of the four-wheel drive vehicle , This will speed up the wear and tear of vehicle parts, and even damage, which also reduces the safety of the vehicle.
例如,较常见的一些车型的轮胎型号通常为225/55R19,其中,225表示轮胎胎面宽度,55表示轮胎扁平比,R19表示轮胎所适合轮圈的尺寸为19寸。而相应的非全尺寸备胎的型号通常为T135/90R17,可见,非全尺寸备胎与正常轮胎相差较大,经计算可得两者的周长相差168mm左右,左右轮的周长偏差将在7.6%以上。For example, the tire model of some of the more common models is usually 225/55R19, where 225 indicates the tire tread width, 55 indicates the tire aspect ratio, and R19 indicates that the size of the tire suitable for the rim is 19 inches. The model of the corresponding non-full-size spare tire is usually T135/90R17. It can be seen that the difference between the non-full-size spare tire and the normal tire is relatively large. After calculation, the circumference difference between the two is about 168mm, and the circumference deviation of the left and right wheels will be Above 7.6%.
值得一提的是,之所以全尺寸备胎没有占据整个市场,存在非全尺寸备胎和零压备胎的市场空间,是因为如下几方面原因:It is worth mentioning that the reason why full-size spare tires do not occupy the entire market and there is market space for non-full-size spare tires and zero-pressure spare tires is because of the following reasons:
一、节省空间。全尺寸备胎是三种备胎类型中体积最大的备胎,将其放置在后备箱内将占据大量的后备箱空间,不利于再放置其他杂物。而其他两种类型的备胎尺寸较小,放置在后备箱内可以保留较大的后备箱空间。1. Save space. The full-size spare tire is the largest among the three types of spare tires. Placing it in the trunk will occupy a large amount of trunk space, which is not conducive to placing other sundries. The other two types of spare tires are smaller in size, and they can reserve a larger trunk space when placed in the trunk.
二、节约成本。随着平价车型的大量出现,对于汽车厂商而言,汽车厂商为了提高竞争力,通常采用降低成本的方式,而备胎的配置即为一个成本点,当汽车销量极高时,各种类型的备胎之间的成本差价将变得较为客观。Second, cost savings. With the emergence of a large number of affordable models, for car manufacturers, in order to improve their competitiveness, car manufacturers usually adopt the method of reducing costs, and the configuration of spare tires is a cost point. When the sales of cars are extremely high, various types of The cost difference between spare tires will become more objective.
三、减轻车重。全尺寸备胎的整体重量是三种备胎类型中重量最大的备胎。当汽车重量较大时,将会对车身稳定性、操纵性等性能产生影响,对于一些将汽车定位于轻量级汽车的品牌而言,车身重量自然是越轻越好,因此,汽车厂商会尽可能降低车重,故而重量较大的全尺寸备胎通常不在优先考虑的范围之内。Three, reduce vehicle weight. The overall weight of the full-size spare wheel is the heaviest of the three spare wheel types. When the weight of the car is heavy, it will have an impact on the stability and handling of the car body. For some brands that position cars as lightweight cars, the lighter the body weight, the better. Therefore, car manufacturers will Keep the weight of the vehicle as low as possible, so a heavy full-size spare wheel is usually not a priority.
为了解决现有技术问题,本申请实施例提供了一种车辆驾驶控制方法、装置和控制设备。下面首先对本申请实施例所提供的车辆驾驶控制方法进行介绍。In order to solve the problems in the prior art, embodiments of the present application provide a vehicle driving control method, device and control equipment.

本申请实施例通过车辆各个车轮的轮速,判断各个车轮中是否存在非全尺寸备胎或者零压备胎。当存在非全尺寸备胎或者零压备胎时,可以通过输出预设驾驶控制信息,控制车辆执行相应的驾驶操作或者提醒用户改变驾驶行为,以提高更换有非全尺寸备胎或者零压备胎的车辆在驾驶过程中的安全性。In the embodiment of the present application, it is judged whether there is a non-full-size spare tire or a zero-pressure spare tire in each wheel according to the wheel speed of each wheel of the vehicle. When there is a non-full-size spare tire or a zero-pressure spare tire, the preset driving control information can be output to control the vehicle to perform corresponding driving operations or remind the user to change the driving behavior, so as to improve the efficiency of replacing a non-full-size spare tire or zero-pressure spare tire.

在一些实施例中,预设备胎可以是非全尺寸备胎或零压备胎。由于预设备胎的尺寸与原车辆轮胎的尺寸不同,基于此,预设备胎的轮速和原车辆轮胎的轮速也不同,因此,可以通过各个轮胎的轮速,判断是否存在预设备胎。In some embodiments, the pre-installed tire may be a non-full size spare tire or a zero pressure spare tire. Since the size of the pre-installed tires is different from that of the original vehicle tires, the wheel speed of the pre-installed tires is also different from that of the original vehicle tires. Therefore, the wheel speed of each tire can be used to determine whether there are pre-installed tires.
可选的,步骤S120的一种实现方式可以如下:根据第一前轮的轮速、第二前轮的轮速、第一后轮的轮速以及第二后轮的轮速,计算目标车辆的前轴和后轴之间的速度差值比例;在速度差值比例大于预设比例阈值的情况下,判断第一前轮、第二前轮、第一后轮以及第二后轮中存在预设备胎;在速度差值比例小于或者等于预设比例阈值的情况下,判断第一前轮、第二前轮、第一后轮以及第二后轮中不存在预设备胎。Optionally, an implementation of step S120 may be as follows: Calculate the target vehicle according to the wheel speed of the first front wheel, the wheel speed of the second front wheel, the wheel speed of the first rear wheel, and the wheel speed of the second rear wheel The speed difference ratio between the front axle and the rear axle; in the case that the speed difference ratio is greater than the preset ratio threshold, it is judged that there is a Pre-installation of tires: when the speed difference ratio is less than or equal to the preset ratio threshold, it is judged that there is no pre-installation tire among the first front wheel, the second front wheel, the first rear wheel and the second rear wheel.
在一些实施例中,前轴和后轴之间的速度差值比例,又称为轴间速差。申请人发现,无论是两驱车还是四驱车,对于不存在上述预设备胎的车辆,在行驶过程中车辆的前轴和后轴之间的速度差值比例通常会低于一定比例,而存在上述预设备胎的车辆,在行驶过程中车辆的前轴和后轴之间的速度差值比例通常会高于该比例。基于上述发现,可以设置一个预设比例阈值,例如7.6%,如果速度差值比例大于预设比例阈值,则可以认为存在预设备胎,否则认为不存在预设备胎。In some embodiments, the ratio of the speed difference between the front axle and the rear axle is also referred to as the inter-axle speed difference. The applicant found that, whether it is a two-wheel-drive vehicle or a four-wheel-drive vehicle, for a vehicle that does not have the above-mentioned pre-installed tires, the ratio of the speed difference between the front axle and the rear axle of the vehicle during driving is usually lower than a certain ratio, while the above-mentioned Vehicles with pre-installed tires will normally have a higher ratio of the speed difference between the front and rear axles of the vehicle during travel. Based on the above findings, a preset ratio threshold can be set, such as 7.6%. If the speed difference ratio is greater than the preset ratio threshold, it can be considered that there is a pre-installation tire, otherwise it is considered that there is no pre-installation tire.
具体的,可以获取第一前轮的轮速和第二前轮的轮速的第一平均值,以及第一后轮的轮速和第二后轮的轮速的第二平均值。之后,可以将第一平均值与第二平均值的差值占目标平均值的比例的绝对值,确定为速度差值比例。其中,目标平均值可以取第一平均值,也可以取第二平均值,这里不对其进行具体限定。接着,对计算得到的速度差值比例与预设比例阈值的大小关系进行比较。如果速度差值比例大于预设比例阈值,则判断第一前轮、第二前轮、第一后轮以及第二后轮中存在预设备胎。如果速度差值比例小于或者等于预设比例阈值,则判断第一前轮、第二前轮、第一后轮以及第二后轮中不存在预设备胎。Specifically, a first average value of the wheel speed of the first front wheel and the wheel speed of the second front wheel, and a second average value of the wheel speed of the first rear wheel and the wheel speed of the second rear wheel may be acquired. Afterwards, the absolute value of the ratio of the difference between the first average value and the second average value to the target average value may be determined as the speed difference ratio. Wherein, the target average value may be the first average value, or may be the second average value, which is not specifically limited here. Next, the magnitude relationship between the calculated speed difference ratio and the preset ratio threshold is compared. If the speed difference ratio is greater than the preset ratio threshold, it is determined that there is a pre-installed tire in the first front wheel, the second front wheel, the first rear wheel and the second rear wheel. If the speed difference ratio is less than or equal to the preset ratio threshold, it is determined that there is no pre-installed tire among the first front wheel, the second front wheel, the first rear wheel and the second rear wheel.
值得一提的是,在同等车况下,由于车辆在转弯行驶过程中前轴和后轴之间的速度差值比例,大于直线行驶过程中前轴和后轴之间的速度差值比例,因此,可以设置两种预设比例阈值,即转弯行驶过程对应的预设比例阈值和直线行驶过程对应的预设比例阈值。如此,可以根据车辆行驶过程的类型,选择相应的预设比例阈值,以判断是否存在预设备胎。这样,可以更精确地对预设备胎进行判断,避免出现误判情况。It is worth mentioning that, under the same vehicle conditions, since the speed difference ratio between the front axle and the rear axle is greater than the speed difference ratio between the front axle and the rear axle when the vehicle is turning, the , two preset ratio thresholds can be set, that is, the preset ratio threshold corresponding to the turning process and the preset ratio threshold corresponding to the straight-line driving process. In this way, a corresponding preset ratio threshold can be selected according to the type of the vehicle's driving process, so as to determine whether there is a pre-installed tire. In this way, the pre-installation tire can be judged more accurately, and misjudgment can be avoided.
具体的,可以根据方向盘转角信号来识别车辆当前的车辆行驶过程的类型,例如检测到左转信号时,可以认为车辆处于转弯行驶过程。Specifically, the type of the current vehicle driving process of the vehicle can be identified according to the steering wheel angle signal, for example, when a left turn signal is detected, the vehicle can be considered to be in the process of turning.
需要说明的是,除了直线行驶过程和转弯行驶过程这两种驾驶场景之外,还可以根据需求,对其它类型的驾驶场景设置相应的预设比例阈值,本申请实施例不对其进行限定。It should be noted that in addition to the two driving scenarios of straight-line driving and turning driving, corresponding preset ratio thresholds can also be set for other types of driving scenarios according to requirements, which is not limited in this embodiment of the present application.
可选的,步骤S120的再一种实现方式可以如下:获取第一前轮的轮速、第二前轮的轮速、第一后轮的轮速以及第二后轮的轮速的方差;在方差大于预设方差阈值的情况下,判断第一前轮、第二前轮、第一后轮以及第二后轮中存在预设备胎;在方差小于或者等于预设方差阈值的情况下,判断第一前轮、第二前轮、第一后轮以及第二后轮中不存在预设备胎。Optionally, another implementation of step S120 may be as follows: obtain the wheel speed of the first front wheel, the wheel speed of the second front wheel, the wheel speed of the first rear wheel, and the variance of the wheel speed of the second rear wheel; When the variance is greater than the preset variance threshold, it is determined that there is a pre-installed tire in the first front wheel, the second front wheel, the first rear wheel, and the second rear wheel; when the variance is less than or equal to the preset variance threshold, It is judged that there is no pre-installed tire in the first front wheel, the second front wheel, the first rear wheel and the second rear wheel.
在一些实施例中,申请人发现,无论是两驱车还是四驱车,对于不存在上述预设备胎的车辆,在行驶过程中各个车轮的轮速的方差较小,而存在上述预设备胎的车辆,在行驶过程中各个车轮的轮速的方差较大。基于上述发现,可以设置一个预设方差阈值,如果各个车轮的轮速的方差大于该预设方差阈值,则可以认为存在预设备胎,否则认为不存在预设备胎。In some embodiments, the applicant found that no matter whether it is a two-wheel drive vehicle or a four-wheel drive vehicle, for vehicles without the above-mentioned pre-installed tires, the variance of the wheel speeds of each wheel during driving is small, while there are vehicles with the above-mentioned pre-installed tires , the variance of the wheel speed of each wheel is large during driving. Based on the above findings, a preset variance threshold can be set. If the variance of the wheel speeds of each wheel is greater than the preset variance threshold, it can be considered that there is a pre-installation tire, otherwise it is considered that there is no pre-installation tire.
步骤S130、若存在预设备胎,则输出预设驾驶控制信息。Step S130, if there is a pre-installed tire, then output preset driving control information.
在一些实施例中,预设驾驶控制信息可以是用于提醒用户改变驾驶行为的提示信息,也可以是对车辆的控制指令。In some embodiments, the preset driving control information may be prompt information for reminding the user to change the driving behavior, or may be a control instruction for the vehicle.
在一些实施例中,预设驾驶控制信息可以是驾驶速度低于预设备胎速度阈值的提示信息,例如语音播报如下信息,“当前备用轮胎已投入使用,请将车速控制在80km/h以内,以确保车辆行驶安全”,或者在仪表盘上显示相应提示信息。此外,为了提升车辆的安全性,预设驾驶控制信息还可以是将最大行驶速度设置为预设备胎速度阈值的控制指令,以限制车辆的行驶速度,从根本上避免车辆的行驶速度超过预设备胎速度阈值。另外,还可以统计更换预设备胎后车辆的行驶里程,并在行驶里程超过一定里程后,提示用户及时将预设备胎换下,如此,可以进一步提升安全性。In some embodiments, the preset driving control information may be prompt information indicating that the driving speed is lower than the preset tire-installation speed threshold, for example, the voice broadcasts the following information, "The current spare tire has been put into use, please control the vehicle speed within 80km/h, To ensure the safety of the vehicle", or display the corresponding prompt information on the instrument panel. In addition, in order to improve the safety of the vehicle, the preset driving control information can also be a control command to set the maximum driving speed as the preset tire speed threshold, so as to limit the driving speed of the vehicle and fundamentally avoid the driving speed of the vehicle exceeding the preset tire speed threshold. tire speed threshold. In addition, it can also count the mileage of the vehicle after replacing the pre-installed tires, and prompt the user to replace the pre-installed tires in time after the mileage exceeds a certain mileage, which can further improve safety.
在一些实施例中,若存在预设备胎,对于四驱车这一类型的目标车辆,尤其是适时四驱类型,如果使用四驱模式驾驶,由于轴间速差较大,会对传动***零件造成影响,缩短零件使用寿命,造成摩擦组的烧蚀风险,降低了车辆的安全性。考虑到上述情况,当目标车辆处于四驱模式时,可以通过预设驾驶控制信息,提示用户进入两驱模式,或者控制车辆进入两驱模式。In some embodiments, if there is a pre-installed tire, for the target vehicle of the four-wheel drive type, especially the timely four-wheel drive type, if the four-wheel drive mode is used to drive, due to the large speed difference between the axles, it will cause damage to the transmission system components. Impact, shorten the service life of parts, cause the risk of ablation of the friction group, and reduce the safety of the vehicle. Considering the above situation, when the target vehicle is in the four-wheel drive mode, the user may be prompted to enter the two-wheel drive mode through preset driving control information, or the vehicle may be controlled to enter the two-wheel drive mode.
为了更好地理解四驱车,下面对四驱车的驾驶原理进行介绍。In order to better understand the four-wheel drive, the driving principle of the four-wheel drive is introduced below.
分动器是四驱车的汽车动力传动***的重要组件,它的主要作用是将变速器输出的动力分配到前、后传动轴,通过主减速器、驱动轴将扭矩传递至4个车轮,从而实现四轮驱动。分动器通常包括高速驱动模式和低速驱动模式(以下简称4L模式),其中,高速驱动模式包括四驱模式(以下简称4WD模式)、高速两驱模式(以下简称2H模式)、高速四驱模式(以下简称4H模式)。The transfer case is an important component of the power transmission system of a four-wheel drive vehicle. Its main function is to distribute the power output by the transmission to the front and rear drive shafts, and transmit the torque to the four wheels through the final drive shaft and the final drive shaft to achieve four-wheel drive. The transfer box usually includes a high-speed driving mode and a low-speed driving mode (hereinafter referred to as 4L mode), among which, the high-speed driving mode includes four-wheel drive mode (hereinafter referred to as 4WD mode), high-speed two-wheel drive mode (hereinafter referred to as 2H mode), high-speed four-wheel drive mode (hereinafter referred to as 4H mode).
当分动器处于4H模式时,分动器会将摩擦组压紧,按1:1输出动力,用于泥地、沙地行驶。当分动器处于4L模式时,分动器会将变速器的输出扭矩放大2.5倍以上,使前后桥获得更大的输入扭矩,提升车辆的动力性,从容面对非铺装路及地形复杂的路况。而车辆行驶在较平顺的路况下时,则可以使分动器处于高速驱动模式,使车辆具有更好的燃油经济性。因此,通过使分动器模式切换,可以改善车辆在不同路况下的动力性及燃油经济性。When the transfer case is in 4H mode, the transfer case will compress the friction group and output power according to 1:1, which is used for driving on muddy and sandy ground. When the transfer case is in 4L mode, the transfer case will amplify the output torque of the transmission by more than 2.5 times, so that the front and rear axles can obtain greater input torque, improve the power of the vehicle, and calmly face non-paved roads and road conditions with complex terrain . When the vehicle is running on a relatively smooth road condition, the transfer case can be placed in a high-speed driving mode, so that the vehicle has better fuel economy. Therefore, by switching the transfer case mode, the power performance and fuel economy of the vehicle under different road conditions can be improved.
在一些实施例中,对于四驱车,当判断出存在预设备胎时,可以对四驱车辆的当前驾驶模式进行获取。具体的,可以通过分动器控制设备主动采集驾驶模式开关信号、车身电子稳定***信号、变速器档位信号、发动机状态信号等信息,以判断当前驾驶模式是否为四驱模式。In some embodiments, for a four-wheel drive vehicle, when it is determined that there is a pre-installed tire, the current driving mode of the four-wheel drive vehicle may be acquired. Specifically, information such as the driving mode switch signal, vehicle electronic stability system signal, transmission gear position signal, and engine status signal can be actively collected through the transfer case control device to determine whether the current driving mode is the four-wheel drive mode.
之后,在当前驾驶模式为四驱模式的情况下,输出将驾驶模式切换至两驱模式的提示信息,例如语音播报如下信息,“当前备用轮胎已投入使用,请将驾驶模式切换为两驱模式,以确保车辆行驶安全”,或者在仪表盘上显示相应提示信息。Afterwards, when the current driving mode is the four-wheel drive mode, a prompt message for switching the driving mode to the two-wheel drive mode is output, for example, the voice broadcasts the following information, "The current spare tire has been put into use, please switch the driving mode to the two-wheel drive mode , to ensure the safety of the vehicle", or display the corresponding prompt information on the dashboard.
此外,如果在预设时间内,如2分钟内,用户仍未将驾驶模式切换为两驱模式,或者未输出将驾驶模式切换至两驱模式的提示信息,可以输出将扭矩加载门限值提升至预设门限值的控制指令,例如预设门限值可以设定为轴间速差7.6%对应的扭矩加载门限值,以降低摩擦组扭矩分配,保护传动***及行车的安全。In addition, if the user has not switched the driving mode to the two-wheel drive mode within a preset time, such as within 2 minutes, or has not output a prompt message for switching the driving mode to the two-wheel drive mode, an increase in the torque loading threshold can be output. The control command to the preset threshold value, for example, the preset threshold value can be set as the torque loading threshold value corresponding to 7.6% of the speed difference between the shafts, so as to reduce the torque distribution of the friction group and protect the safety of the transmission system and driving.
值得一提的是,上述多种类型的预设驾驶控制信息,可以采取组合输出模式,如此,不仅可以主动提示用户改变驾驶行为,还可以控制车辆执行相应的驾驶操作,更好地提升车辆安全性。It is worth mentioning that the above-mentioned various types of preset driving control information can adopt a combined output mode. In this way, not only can the user be actively prompted to change the driving behavior, but also the vehicle can be controlled to perform corresponding driving operations to better improve vehicle safety. sex.
下面以执行主体为四驱车的分动器控制设备为例,如图2所示,提供一种具体的车辆驾驶控制流程。In the following, a transfer case control device whose executive body is a four-wheel drive vehicle is taken as an example, as shown in FIG. 2 , to provide a specific vehicle driving control process.
首先,获取四驱车的驾驶模式开关信号、轮速信号、变速器档位信号。之后,分动器控制设备根据“轴间速差超过7.6%”这一判断条件,判断车辆是否使用非全尺寸备胎。如果使用非全尺寸备胎,分动器控制设备继续判断车辆驾驶模式是否为2H模式。如果是2H模式,则请求发动机、变速器将最高车速限定在80km/h,同时仪表盘提示用户谨慎驾驶;如果不是2H模式,则提示用户切换至2H模式。之后,分动器控制设备判断2分钟内是否切换至2H模式,如果未切换至2H模式,则提升扭矩加载门限值。First, obtain the driving mode switch signal, wheel speed signal, and transmission gear signal of the four-wheel drive vehicle. After that, the transfer case control device judges whether the vehicle uses a non-full-size spare tire according to the judging condition of "the speed difference between the axles exceeds 7.6%". If a non-full-size spare tire is used, the transfer case control device continues to judge whether the driving mode of the vehicle is the 2H mode. If it is in 2H mode, the engine and transmission are requested to limit the maximum speed to 80km/h, and the instrument panel prompts the user to drive carefully; if it is not in 2H mode, the user is prompted to switch to 2H mode. Afterwards, the transfer case control device judges whether to switch to the 2H mode within 2 minutes, and if it is not switched to the 2H mode, the torque loading threshold value is increased.
本申请实施例通过车辆各个车轮的轮速,可以判断各个车轮中是否存在非全尺寸备胎或者零压备胎。当存在非全尺寸备胎或者零压备胎时,可以通过输出预设驾驶控制信息,控制车辆执行相应的驾驶操作,或者提醒用户改变驾驶行为,极大地提高了更换有非全尺寸备胎或者零压备胎的车辆在驾驶过程中的安全性。In the embodiment of the present application, through the wheel speed of each wheel of the vehicle, it can be judged whether there is a non-full-size spare tire or a zero pressure spare tire in each wheel. When there is a non-full-size spare tire or zero-pressure spare tire, the vehicle can be controlled to perform corresponding driving operations by outputting preset driving control information, or remind the user to change the driving behavior, which greatly improves the efficiency of replacing a non-full-size spare tire or The vehicle with zero pressure spare tire is safe during driving.
此外,通过轮速判断车辆中是否存在预设备胎的方式,易于开发,具有开发成本低的优点。In addition, the method of judging whether there is a pre-installed tire in the vehicle by the wheel speed is easy to develop and has the advantage of low development cost.
