[0018] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. The illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0020] like Figure 1 A hill assist control method shown includes the following steps: S100: Acquire target vehicle information of the vehicle; S200: When the target vehicle information meets the first preset condition, turning on or keeping on the hill assist function of the vehicle, and controlling the brakes of the vehicle to prevent the vehicle from sliding down the slope; S300: When the target vehicle information meets the second preset condition, turn off or keep off the hill assist function of the vehicle, and control the torque of the motor of the vehicle to prevent the vehicle from sliding down the slope.

[0021] By adopting the above technical solution, when the target vehicle information meets different preset conditions, different anti-slope methods are adopted, which can improve the starting speed and driving efficiency of the vehicle in some driving scenarios. In other words, the above hill assist control method can more reasonably determine the timing of turning on and off the hill assist function, so that the timing of turning on and off the hill assist function can be more matched with the actual working conditions of the vehicle, which helps to improve the user experience.

[0022] In specific implementation, the target vehicle information of the vehicle is usually information related to the vehicle's driving, such as: the road surface information of the road the vehicle is currently traveling on, the vehicle's vehicle status information, the vehicle's vehicle component status information, the vehicle's current driver's driving intention information, and the weather information of the area where the vehicle is located. Part of the target vehicle information can be measured by the vehicle's onboard sensor device, such as the road surface information of the road the vehicle is currently traveling on can be measured by the onboard sensor device. Part of the target vehicle information can be obtained from a cloud server, such as the weather information of the area where the vehicle is located can be obtained from a cloud server.

[0023] In some embodiments, the target vehicle information includes the road surface information of the road the vehicle is currently traveling on, the vehicle status information of the vehicle, the vehicle component status information of the vehicle, the driving intention information of the current driver of the vehicle, and the weather information of the area where the vehicle is located. In a specific implementation, the road surface information of the road the vehicle is currently traveling on usually includes the slope information of the road the vehicle is currently traveling on. The vehicle status information usually includes the gear information, speed information, fuel information, vehicle weight information and configuration information of the vehicle. The vehicle component status information usually includes the power information of the vehicle power battery and the available capacity information of the motor. The current driver's driving intention information usually includes the vehicle's driving mode information and the current driver's driving style information. The use of the above-mentioned target vehicle information helps to more reasonably determine the timing of turning on and off the vehicle's hill assist function.

[0024] In some embodiments, when the target vehicle information satisfies the first sub-condition of the preset second preset condition, the vehicle is in a scene of parking on a ramp; when the target vehicle information satisfies the second sub-condition of the preset second preset condition, the vehicle is in a scene of turning around on a ramp. By adopting the above technical solution, by setting corresponding sub-conditions for the scene of parking on a ramp and the scene of turning around on a ramp, the user's speed of reverse parking and parallel parking on a ramp can be improved, and the speed of the user's turning around on a ramp can be improved, thereby alleviating the problem that the user perceives that the whole vehicle responds too slowly in the above scenarios.

[0025] In some embodiments, when the target vehicle information meets all of the following conditions, it is determined that the target vehicle information meets the first preset condition: the slope of the road the vehicle is currently traveling on is greater than the first preset value, the gear of the vehicle is the driving gear and the vehicle is traveling in a climbing direction, the vehicle is stationary, and the vehicle's hill assist function is in an enabled state; otherwise, it is determined that the target vehicle information meets the second preset condition. Using the above technical solution and reasonably setting the determination scheme of the first preset condition and the second preset condition is helpful to more reasonably determine the timing of turning on and off the vehicle's hill assist function.

[0026] In specific implementation, the initial value of the first preset value can be set to 3%. The driving gear of the vehicle includes a forward gear and a reverse gear. When the gear of the vehicle is the forward gear and the front of the vehicle is facing upward, the vehicle is determined to be in a climbing state. When the gear of the vehicle is the reverse gear, the front of the vehicle is facing downward and the vehicle is moving backward, the vehicle is determined to be in a climbing state. When the speed of the vehicle is less than 0.5 km / h, it can be determined that the vehicle is stationary.

[0027] In some embodiments, the hill assist control method includes the following steps: when the target vehicle information satisfies any third preset condition among a plurality of third preset conditions, the hill assist function of the vehicle is set to be enabled; the plurality of third preset conditions include: the slope of the road the vehicle is currently traveling on is greater than the second preset value; the slope of the road the vehicle is currently traveling on is greater than the third preset value and the vehicle mass of the vehicle is greater than the fourth preset value; the sunshine intensity in the area where the vehicle is located is less than the fifth preset value; the vehicle is a pure electric vehicle, and the power of the vehicle's power battery is less than the sixth preset value; the available capacity of the vehicle's motor is less than the seventh preset value; the vehicle is a hybrid vehicle, the fuel volume of the vehicle is less than the eighth preset value, and the power of the vehicle's power battery is less than the ninth preset value; the weather in the area where the vehicle is located is rainy or snowy; the parking style of the current driver of the vehicle is a non-aggressive style; the driving mode of the vehicle is an energy-saving mode. The above technical solution is adopted, and by setting the state of whether the vehicle's hill assist function can be activated, it is helpful to more reasonably determine the timing of turning on and off the vehicle's hill assist function.

[0028] In specific implementation, the initial value of the second preset value can be set to 15%, and the initial value of the third preset value can be set to 10%. The fifth preset value can be set as needed, and the following conditions need to be met: when the sunlight intensity is less than the fifth preset value, the light intensity is dark enough to affect the current driver's line of sight. The initial value of the sixth preset value can be set to 5%. In specific implementation, the sixth preset value can be determined based on the lower limit of the vehicle's motor's anti-slip ability or considering extending the driving range. The initial value of the seventh preset value can be set to 5%. In specific implementation, the seventh preset value can be determined based on the lower limit of the vehicle's motor's anti-slip ability. The initial value of the eighth preset value can be set to 5%. The initial value of the ninth preset value can be set to 5%. The weather in the area where the vehicle is located is rainy or snowy, considering that the vehicle is more difficult to operate on rainy or snowy days.

[0029] As a specific example, the hill assist control method includes the following steps: when the target vehicle information satisfies any of the fourth preset conditions in a plurality of fourth preset conditions, it is determined that the available capacity of the vehicle motor is less than the seventh preset value; the plurality of fourth preset conditions include: the vehicle motor has a fault of a first preset level or above; the vehicle power battery has a fault of a second preset level or above; the temperature of the vehicle power battery is lower than the tenth preset value; the temperature of the vehicle power battery is higher than the eleventh preset value. The above technical solution can better determine the vehicle status information and vehicle component status information of the vehicle, which helps to more reasonably determine the timing of turning on and off the vehicle hill assist function.

[0030] In a specific implementation, the first preset level can be set to level 3, the second preset level can be set to level 5, the initial value of the tenth preset value can be set to -35°C, and the initial value of the eleventh preset value can be set to 50°C.

[0031] As a specific example, the hill assist control method includes the following steps: when the target vehicle information satisfies any fifth preset condition among multiple fifth preset conditions, the current driver's parking style is determined to be an aggressive style; otherwise, the current driver's parking style is determined to be a non-aggressive style; the multiple fifth preset conditions include: during the process of the vehicle's gear shifting from D gear to R gear, the current driver's time of stepping on the accelerator pedal is less than the twelfth preset value; during the process of the vehicle's gear shifting from R gear to D gear, the current driver's time of stepping on the accelerator pedal is less than the thirteenth preset value; during the process of the vehicle's gear shifting from D gear to R gear, the rate of change of the vehicle's steering wheel angle is greater than the fourteenth preset value; during the process of the vehicle's gear shifting from R gear to D gear, the rate of change of the vehicle's steering wheel angle is greater than the fifteenth preset value. The above technical solution can better determine the current driver's driving style and driving intention, which helps to more reasonably determine the timing of turning on and off the vehicle's hill assist function.

[0032] In a specific implementation, the initial value of the twelfth preset value can be set to 0.25S, the initial value of the thirteenth preset value can be set to 0.25S, the initial value of the fourteenth preset value can be set to 360° / S, and the initial value of the fifteenth preset value can be set to 360° / S.

[0033] More specifically, when the vehicle's gear is switched from D gear to R gear, the time the current driver steps on the accelerator pedal is less than the twelfth preset value; or, when the vehicle's gear is switched from R gear to D gear, the time the current driver steps on the accelerator pedal is less than the thirteenth preset value, it can be determined that the vehicle is in a scene of parking on a slope.

[0034] When the vehicle's gear is switched from D gear to R gear, when the rate of change of the vehicle's steering wheel angle is greater than the fourteenth preset value; or when the vehicle's gear is switched from R gear to D gear, when the rate of change of the vehicle's steering wheel angle is greater than the fifteenth preset value, it can be determined that the vehicle is in a scenario of turning around on a slope.

[0035] In some embodiments, the hill assist control method includes the following steps: when the target vehicle information does not meet all the third preset conditions in the plurality of third preset conditions, the hill assist function of the vehicle is set to a non-activatable state. In specific implementation, it can be determined whether the hill assist function or the torque of the vehicle motor is controlled to prevent the vehicle from sliding down the slope by judging whether the hill assist function of the vehicle is in an activated state, which has the characteristic of being easy to implement.

[0036] In a specific implementation, whether the hill assist function can be enabled can be set by setting the hill assist scene flag. For example, when the hill assist scene flag is activated, the hill assist function is enabled; when the hill assist scene flag is not activated, the hill assist function is not enabled.

[0037] With the above-mentioned hill assist control method, when the vehicle's hill assist scene flag is not activated, the hill assist function cannot be activated, and the vehicle's motor torque can be controlled to prevent slipping. The motor torque control method is not limited here, and the motor torque can be obtained by looking up the table based on the slope information of the current road the vehicle is traveling on. In specific implementation, the motor torque can be closed-loop controlled according to the motor speed, or it can be closed-loop controlled according to the vehicle speed.

[0038] By adopting the above-mentioned hill assist control method, when the hill assist function of the vehicle is activated, the vehicle can be prevented from sliding down the slope by controlling the brake.

[0039] like Figure 2 As shown, as a specific example, the hill assist control method includes the following steps: S1000: Determine whether the hill assist function of the vehicle is in an enabled state. When the hill assist function of the vehicle is in an enabled state, execute S2000; when the hill assist function of the vehicle is not in an enabled state, execute S3000; S2000: Determine whether the hill start assist function of the vehicle is in an on state. When the hill start assist function of the vehicle is in an on state, execute S4000; otherwise, execute S3000; S3000: controlling the torque of the motor of the vehicle to prevent the vehicle from sliding down a slope; S4000: Control the vehicle's brakes to prevent the vehicle from rolling down the slope.

[0040] like Figure 3 As shown, the present invention further proposes a hill assist control system 10 , which includes an acquisition module 20 , a first control module 30 , a second control module 40 , a determination module 50 and a setting module 60 .
