[0002] When a car is driving on a low-adhesion road surface, especially on a slope, the wheels are very likely to slip. To address this problem, vehicles are usually equipped with ESP (Electronic Stability Program), which limits the torque output of the power source and controls the wheel speed to maintain the vehicle's stable driving. However, when a vehicle encounters a slipping condition on a low-adhesion slope road surface, in addition to limiting the torque and speed, it is also necessary to ensure sufficient climbing ability, which places higher requirements on ESP control. Although the traditional ESP system can alleviate the slipping phenomenon to a certain extent, when facing high slopes and low road adhesion, if the gearbox gear is too high, it will significantly reduce the vehicle's driving force, thereby reducing the climbing ability and making it difficult for the vehicle to climb.

[0043] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0044] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0045] The main solution of the embodiment of the present application is: obtaining the vehicle speed information, slope and accelerator pedal opening; obtaining the target transmission gear according to the vehicle speed information, the slope and the accelerator pedal opening; and controlling the vehicle to climb the slope according to the target transmission gear.

[0046] In the prior art, when a car is driving on a low-adhesion road surface, especially in a slope environment, the wheels are very likely to slip. In order to deal with this problem, vehicles are usually equipped with ESP (Electronic Stability Program), which limits the torque output of the power source and controls the wheel speed to maintain the stable driving of the vehicle. However, when a vehicle encounters a slipping condition on a low-adhesion slope road surface, in addition to limiting the torque and speed, it is also necessary to ensure sufficient climbing ability, which puts higher requirements on the control of ESP. Although the traditional ESP system can alleviate the slipping phenomenon to a certain extent, in the face of high slopes and low road adhesion, if the gearbox gear is too high, it will significantly reduce the vehicle's driving force, thereby reducing the climbing ability and causing the vehicle to have difficulty climbing. Therefore, how to improve the climbing performance of the vehicle is a problem that urgently needs to be solved.

[0047] This application realizes the control of the automatic transmission control unit over the transmission gear by analyzing the data information of the vehicle during the climbing process to adapt to the driving requirements under different slopes, throttles and vehicle speed conditions, thereby significantly improving the climbing performance while ensuring stable driving of the vehicle.

[0048] It should be noted that the execution subject of this embodiment can be a vehicle climbing control system, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device that can realize the above-mentioned vehicle climbing control function, etc., and this embodiment does not specifically limit this. The following takes the vehicle climbing control system as an example to illustrate this embodiment and the following embodiments.

[0049] Based on this, the embodiment of the present application provides a vehicle climbing control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle climbing control method of the present application.

[0050] In this embodiment, the vehicle climbing control method includes steps S10 to S30:

[0051] Step S10: Obtain vehicle speed information, slope and accelerator pedal opening.

[0052] It should be noted that vehicle speed information refers to various types of vehicle speed information when the vehicle is running, generally including the overall speed of the vehicle and the rotation speed of the wheels. It is understandable that this is because the rotation speed of the wheels plays a key role in determining whether the wheels are slipping. The accelerator pedal opening directly reflects the driver's demand for vehicle acceleration and is an important basis for vehicle power distribution and gear control.

[0053] In addition, it should be noted that in this step, the vehicle speed information, slope and accelerator pedal opening are obtained by sensors and controllers installed on the vehicle. First, the vehicle speed information is obtained in real time through the vehicle speed sensor, which is usually installed on the gearbox or wheel of the vehicle and can accurately measure and output the current vehicle speed data. In addition, the wheel speed sensor will also provide wheel speed information of the wheel at the same time. The slope information is obtained through the angle sensor. The angle sensor is usually installed on the suspension system or chassis of the vehicle, which can sense the slope changes of the vehicle's driving road in real time and transmit this information to the vehicle's control unit. The accelerator pedal opening is monitored by the accelerator pressure sensor, which is installed on the accelerator pedal and can sense the depth of the driver's pedal depression, thereby reflecting the driver's acceleration intention.

[0054] Step S20: obtaining a target gearbox gear according to the vehicle speed information, the slope and the accelerator pedal opening.

[0055] It should be noted that the target gearbox gear refers to the gear used to control the vehicle to ensure the vehicle's climbing performance on low-adhesion, steep-slope roads under the current circumstances. In this step, after the ECU obtains the vehicle speed information, slope, and accelerator pedal opening, it will pass this information to the ESP (Electronic Stability Program) and TCU (Telematics Control Unit) for processing. The system will determine whether the vehicle is slipping based on the vehicle speed information, and at the same time evaluate the vehicle's current required climbing ability based on the slope, and determine the target gearbox gear required to control the current vehicle based on the accelerator pedal opening.

[0056] Step S30: Controlling the vehicle to climb a slope according to the target gearbox gear position.

[0057] It should be noted that after the system obtains the target gearbox position, the TCU will immediately control the gearbox to perform the corresponding shifting operation and adjust the gearbox position to the target gear (such as 1st gear). At the same time, the system will also adjust its torque control and wheel speed control strategies according to the current real-time working conditions to cooperate with the gear control operation of the TCU to jointly improve the vehicle's climbing performance. For example, after the vehicle enters the target control gear (such as 1st gear), the vehicle's traction is improved due to the increase in the gear ratio of the gearbox, helping the vehicle to overcome the resistance of the slope. At the same time, ESP maintains the adhesion of the wheels and prevents wheel slippage by adjusting the braking force and driving force distribution of the wheels.

[0058] In addition, it should be noted that in the process of controlling the vehicle to climb a slope, the ECU, ESP and TCU will maintain close communication and cooperation to ensure that the vehicle can be controlled promptly and effectively under various working conditions. In addition, various sensors installed on the vehicle will also monitor the vehicle's driving status and changes in the external environment in real time, providing accurate and reliable input information for the control system.

[0059] This embodiment provides a vehicle climbing control method, which obtains the vehicle speed information, slope and accelerator pedal opening; obtains the target gearbox gear according to the vehicle speed information, the slope and the accelerator pedal opening; and controls the vehicle to climb the slope according to the target gearbox gear. In summary, this embodiment realizes the control of the gearbox gear by the automatic gearbox control unit by analyzing the data information of the vehicle during the climbing process to adapt to the driving requirements under different slopes, throttles and vehicle speeds, thereby significantly improving the climbing performance while ensuring the stable driving of the vehicle.

[0060] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , Figure 2 This is a flow chart of the second embodiment of the vehicle climbing control method of the present application, wherein step S20 specifically includes:

[0061] Step S201: Obtain the vehicle speed and wheel speed according to the vehicle speed information.

[0062] It should be noted that vehicle speed refers to the distance traveled by the vehicle in a unit of time, while wheel speed refers to the number of revolutions of the wheel per minute. The two are converted through the circumference of the tire to obtain the actual driving speed of the vehicle. In this step, the vehicle speed information and wheel speed are obtained in real time through sensors installed on the vehicle. The vehicle speed sensor is usually installed on the non-driven wheel of the vehicle, and the vehicle speed is estimated by measuring the wheel speed and the circumference of the tire. The wheel speed is directly provided by the wheel speed sensor, which is usually installed near the wheel bearing. After obtaining this data, the electronic stability program (ESP) will further process this information to determine the current vehicle speed and wheel speed.

[0063] Step S202: Determine the vehicle state according to the vehicle speed and the wheel speed.

[0064] It should be noted that the vehicle status refers to the comprehensive performance of the vehicle under the current driving conditions, including whether it is slipping. Figure 3 As shown in the figure, in this step, ESP will use the obtained vehicle speed and wheel speed data, combined with the preset algorithm, to judge the current state of the vehicle. For example, when the vehicle is driving on a slope, ESP will continuously monitor the changes in vehicle speed and wheel speed. If the wheel speed is significantly higher than the ideal speed corresponding to the vehicle speed, it means that the wheel may be slipping. At this time, ESP will record the current vehicle speed and wheel speed data to determine the vehicle status.

[0065] In a feasible implementation manner, the step S202 specifically includes:

[0066] Step A10: Obtaining a corresponding standard vehicle speed according to the wheel speed.

[0067] It should be noted that the standard vehicle speed refers to the theoretical driving speed that the vehicle should reach, calculated based on the wheel speed or other vehicle parameters, when the vehicle is not skidding or sliding. Figure 3As shown, in this step, ESP will obtain the rotation speed information of the wheel in real time, and based on the parameters such as the diameter of the vehicle tire and the current load of the vehicle, the wheel speed is converted into the corresponding standard speed using a preset conversion relationship or query table. It is understandable that the main function of this step is to establish a corresponding relationship between the wheel speed and the actual driving speed of the vehicle, so as to analyze whether the vehicle is in a slipping state in the follow-up. For example, when the vehicle is driving on a ramp, if the wheel speed increases sharply, but the actual driving speed of the vehicle (i.e., the standard speed) is not significantly improved, that is, the wheel may be slipping at this time. In order to accurately judge, the ESP system will immediately convert the speed of the vehicle, according to the current wheel speed (e.g., 300 revolutions per minute) and the specific parameters of the vehicle (e.g., tire diameter 27 inches, vehicle fully loaded), by calculating or querying a preset table, it is concluded that the standard speed at this time should be 30 kilometers per hour.

[0068] Step A20: When the absolute value of the difference between the standard vehicle speed and the vehicle speed is greater than a preset deviation threshold, determining that the vehicle state is a slipping state.

[0069] It should be noted that the preset deviation threshold is a value pre-set according to factors such as the specific type of vehicle, usage scenario and performance requirements, and is used to measure the difference between the standard vehicle speed and the actual vehicle speed. It is understandable that a reasonable deviation value setting can effectively avoid misjudgment caused by small speed fluctuations, and can also capture serious skidding in time, ensuring the timeliness and effectiveness of the control strategy.

[0070] In addition, it should be noted that in this step, the system will calculate the difference between the standard vehicle speed obtained in step A10 and the actual vehicle speed (usually provided directly by the vehicle speed sensor). By calculating the difference between the two and judging whether the absolute value of the difference exceeds the preset deviation threshold, it is finally determined whether the vehicle is in a slipping state. The core function of this step is to accurately identify the slipping of the vehicle through quantitative analysis, and provide an accurate basis for the subsequent control strategy.

[0071] Step S203: Obtaining a target control mode state according to the vehicle state and the slope.

[0072] It should be noted that the target control mode state refers to the control strategy determined by ESP based on the current vehicle state and slope information, which aims to achieve the best climbing performance by adjusting the parameters of various vehicle systems. Figure 4 As shown, after the system determines that the vehicle state and slope meet the preset conditions, ESP will decide whether to activate the target control mode based on the preset control strategy.

[0073] In a feasible implementation manner, the step S203 specifically includes:

[0074] Step B10: When the vehicle state is a slipping state and the slope is greater than a preset slope threshold, determining that the target control mode state is an activated state.

[0075] It should be noted that the slipping state refers to the state in which the wheel speed does not match the vehicle speed due to insufficient road adhesion during driving, affecting the normal driving of the vehicle. The preset slope threshold is a parameter set based on factors such as vehicle performance, road conditions and safety requirements. Figure 4 As shown, in this step, the system monitors the state of the vehicle. When the system confirms that the vehicle is in a slipping state and the slope of the slope is greater than a preset slope threshold (for example, a slope of 15%), ESP will send an activation signal of the target control mode to the automatic transmission control unit (TCU) to activate the target control mode state.

[0076] In a feasible implementation manner, after step B10, the method further includes:

[0077] Step B20: When the vehicle speed is greater than a preset vehicle speed threshold, the target control mode state is adjusted to an exit state.

[0078] It should be noted that the preset vehicle speed threshold is a parameter set according to the actual vehicle conditions and road conditions, and is used as a basis for determining when to exit the target control mode. Figure 4 As shown in the figure, in this step, when the target control mode is activated, the TCU will continue to monitor the vehicle speed information. When the vehicle speed increases to exceed the preset speed threshold (such as 50km / h), the TCU determines that the vehicle has sufficient stability and driving force and no longer needs to maintain the target control mode. At this time, the TCU adjusts the target control mode state to the exit state and restores the normal transmission gear control logic.

[0079] It is understandable that in the target control mode, after the vehicle successfully climbs a steep slope, as the vehicle speed gradually increases, when it exceeds 10km / h, the TCU determines that the vehicle is in a stable driving state and no longer requires target gear control, so it adjusts the control mode to the exit state and resumes normal driving.

[0080] Step S204: obtaining a target transmission gear position according to the target control mode state, the vehicle speed and the accelerator pedal opening.

[0081] It should be noted that the target gear position refers to the optimal gear position determined by the TCU based on the current target control mode and vehicle status, which aims to improve the vehicle's driving performance and driving experience by optimizing the power transmission path. Specifically, the system determines the target gear position based on the state of the target control mode, vehicle speed, and preset shift curve.

[0082] In a feasible implementation manner, the step S204 specifically includes:

[0083] Step C10: when the target control mode state is an activated state, obtaining a preset shift curve.

[0084] It should be noted that the preset shift curve is the optimal sliding gear strategy obtained by TCU based on the vehicle dynamics and actual road conditions through a large number of experiments and data analysis. It can provide the best transmission ratio under different climbing conditions, thereby optimizing the climbing performance of power output. Specifically, after the system confirms that it has entered the target control mode (that is, the target control mode state is activated), TCU will call the preset shift curve from the internal storage. It can be understood that the preset shift curve is specially designed to cope with large slopes, low speeds, and slippery roads with low adhesion, and is designed to optimize the vehicle's climbing performance through specific shifting logic.

[0085] Step C20: Obtaining a target gearbox gear position according to the preset gear shift curve, the vehicle speed and the accelerator pedal opening.

[0086] It should be noted that in this step, when the target control mode is activated, the TCU will determine the optimal target gearbox gear under the current state based on the real-time vehicle speed and accelerator pedal opening information, combined with the preset shift curve. Specifically, when the vehicle speed and accelerator pedal opening meet the preset conditions, the TCU will determine the gearbox gear to be 1st gear according to the preset shift curve, so as to make full use of the large speed ratio of 1st gear to provide sufficient driving force and help the vehicle overcome the slope resistance.

[0087] In a feasible implementation manner, the step C20 specifically includes:

[0088] Step C201: When the vehicle speed is less than a preset speed limit and the accelerator pedal opening is greater than a preset accelerator opening threshold, determining a target transmission gear position in a current state according to the preset shift curve.

[0089] It should be noted that the preset speed limit is a speed threshold set based on vehicle performance, road conditions, safety factors and other considerations, and is used to determine whether the vehicle is in a low-speed driving state. The preset throttle opening threshold is also a throttle opening threshold set based on vehicle performance and driving needs, and is used to determine whether the driver intends to output strong power to cope with challenging road conditions such as climbing. For example, during the climbing process, if the driver continues to step on the accelerator deeply (the accelerator pedal opening is greater than the preset throttle opening threshold, such as 40%), and the vehicle speed remains at a low level (less than the preset speed limit, such as 20km / h), the system will determine the gearbox gear to 1st gear according to the preset shift curve to maintain maximum driving force and help the vehicle climb smoothly.

[0090] In this embodiment, various types of vehicle operating information are obtained during the vehicle climbing process, and the coordinated work of ESP and TCU is controlled accordingly. At the same time, a preset shift curve is set, so that the vehicle can maintain maximum driving force when climbing, thereby improving the stability of the vehicle when climbing on low-adhesion slopes.
