[0029] 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 content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed 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 explaining the present invention, rather than for limiting the protection scope of the present invention.

[0030] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. The diagrams only show the components related to the present invention, rather than being drawn according to the number, shape and size of the components in actual implementation. The type, quantity and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0031] Such as Figure 1A ramp assist control method shown as follows includes the following steps:

[0032] S100: Obtain the target vehicle information of the vehicle;

[0033] S200: When the target vehicle information meets the first preset condition, turn on or keep on the ramp assist function of the vehicle, and control the brake of the vehicle to prevent the vehicle from rolling back;

[0034] S300: When the target vehicle information meets the second preset condition, turn off or keep off the ramp assist function of the vehicle, and control the torque of the motor of the vehicle to prevent the vehicle from rolling back.

[0035] Adopting the above technical solution, different anti-rolling-back methods are adopted when the target vehicle information meets different preset conditions, which can improve the starting speed and driving efficiency of the vehicle in some driving scenarios. That is to say, adopting the above ramp assist control method can more reasonably determine the opening and closing times of the ramp assist function, so that the opening and closing times of the ramp assist function can better match the actual working conditions of the vehicle, which helps to improve the user experience.

[0036] In specific implementation, the target vehicle information of the vehicle is usually information related to vehicle driving, such as: the road surface information of the current driving road of the vehicle, the vehicle state information of the vehicle, the vehicle component state 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. Some target vehicle information can be measured by the vehicle's on-board sensing device. For example, the road surface information of the current driving road of the vehicle can be measured by the on-board sensing device. Some target vehicle information can be obtained from the cloud server. For example, the weather information of the area where the vehicle is located can be obtained from the cloud server.

[0037] In some embodiments, the target vehicle information includes the road surface information of the current driving road of the vehicle, the vehicle state information of the vehicle, the vehicle component state 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 specific implementation, the road surface information of the current driving road of the vehicle usually includes the slope information of the current driving road of the vehicle. The vehicle state information usually includes the gear information, vehicle speed information, fuel quantity information, vehicle weight information, and configuration information of the vehicle. The vehicle component state information usually includes the power quantity information of the vehicle power battery and the available capacity information of the motor. The driving intention information of the current driver usually includes the driving mode information of the vehicle and the driving style information of the current driver. Adopting the above target vehicle information helps to more reasonably determine the opening and closing times of the vehicle ramp assist function.

[0038] In some embodiments, when the target vehicle information meets the first sub-condition in the preset second preset condition, the vehicle is in the scenario of parking and entering the garage on a slope; when the target vehicle information meets the second sub-condition in the preset second preset condition, the vehicle is in the scenario of turning around on a slope. By adopting the above technical solution, by setting corresponding sub-conditions for the scenarios of parking and entering the garage on a slope and turning around on a slope, the vehicle entering speed of the user for reverse parking and parallel parking on a slope can be increased, and the turning speed of the user on a slope can be increased, thereby alleviating the problem that the user perceives that the overall vehicle response is too slow in the above scenarios.

[0039] 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 current driving road of the vehicle is greater than the first preset value, the gear of the vehicle is in the drive gear and the traveling direction of the vehicle is uphill, the vehicle is in a stationary state, and the hill-start assist function of the vehicle is in a state where it can be activated; otherwise, it is determined that the target vehicle information meets the second preset condition. By adopting the above technical solution, reasonably setting the determination scheme of the first preset condition and the second preset condition helps to more reasonably determine the timing of turning on and off the hill-start assist function of the vehicle.

[0040] In specific implementation, the initial value of the first preset value can be set to 3%. The drive gears of the vehicle include the forward gear and the reverse gear. When the gear of the vehicle is in the forward gear and the front of the vehicle is facing upward, it is determined that the vehicle is in the uphill state. When the gear of the vehicle is in the reverse gear, the front of the vehicle is facing downward and the vehicle is moving backward, it is determined that the vehicle is in the uphill state. When the vehicle speed is less than 0.5 km / h, it can be determined that the vehicle is in a stationary state.

[0041] In some embodiments, the hill-start assist control method includes the following steps: when the target vehicle information meets any one of the multiple third preset conditions, set the hill-start assist function of the vehicle to a state where it can be activated; the multiple third preset conditions include: the slope of the current driving road of the vehicle is greater than the second preset value; the slope of the current driving road of the vehicle is greater than the third preset value and the total vehicle mass of the vehicle is greater than the fourth preset value; the sunlight 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 battery power of the vehicle power battery is less than the sixth preset value; the available capacity of the vehicle motor is less than the seventh preset value; the vehicle is a hybrid vehicle, the fuel quantity of the vehicle is less than the eighth preset value, and the battery power of the vehicle power battery is less than the ninth preset value; the weather in the area where the vehicle is located is rainy or snowy; the current driver's parking style of the vehicle is non-aggressive; the driving mode of the vehicle is the energy-saving mode. By adopting the above technical solution, by setting the state of whether the hill-start assist function of the vehicle can be activated, it helps to more reasonably determine the timing of turning on and off the hill-start assist function of the vehicle.

[0042] 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 so dark that it affects the line of sight of the current driver. The initial value of the sixth preset value can be set to 5%. In specific implementation, the sixth preset value can be determined according to the lower limit of the anti-rollback ability of the vehicle motor 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 according to the lower limit of the anti-rollback ability of the vehicle motor. 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 operation is more difficult on rainy days or snowy days.

[0043] As a specific example, the ramp assist control method includes the following steps: when the target vehicle information meets any one of the multiple fourth preset conditions, it is determined that the available ability of the vehicle motor is less than the seventh preset value; the multiple fourth preset conditions include: the motor of the vehicle has a fault above the first preset level; the power battery of the vehicle has a fault above the second preset level; 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. By adopting the above technical solution, the vehicle state information and the vehicle component state information of the vehicle can be better determined, which helps to more reasonably determine the timing of turning on and off the vehicle ramp assist function.

[0044] In 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.

[0045] As a specific example, the ramp assist control method includes the following steps: when the target vehicle information meets any one of the multiple fifth preset conditions, it is determined that the current driver's parking style is an aggressive style; otherwise, it is determined that the current driver's parking style is 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 time when the current driver steps 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 time when the current driver steps 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 change rate of the vehicle 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 change rate of the vehicle steering wheel angle is greater than the fifteenth preset value. By adopting the above technical solution, the driving style and driving intention of the current driver can be better determined, which helps to more reasonably determine the timing of turning on and off the vehicle ramp assist function.

[0046] In 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.

[0047] More specifically, when the vehicle's gear is switched from D gear to R gear, and the time when 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, and the time when the current driver steps on the accelerator pedal is less than the thirteenth preset value, it can be determined that the vehicle is in the scenario of parking and entering the garage on a slope.

[0048] When the vehicle's gear is switched from D gear to R gear, and the change rate 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, and the change rate of the vehicle's steering wheel angle is greater than the fifteenth preset value, it can be determined that the vehicle is in the scenario of turning around on a slope.

[0049] In some embodiments, the ramp assist control method includes the following steps: when the target vehicle information does not meet all of the third preset conditions among the multiple third preset conditions, set the ramp assist function of the vehicle to a non - activatable state. In specific implementation, it is possible to determine whether to use the ramp assist function or to control the torque of the vehicle motor to prevent the vehicle from rolling back by judging whether the ramp assist function of the vehicle is in an activatable state, which has the characteristic of being easy to implement.

[0050] In specific implementation, the ramp assist function can be set to be activatable or not by setting a ramp assist scenario flag. For example, when the ramp assist scenario flag is activated, the ramp assist function is in an activatable state; when the ramp assist scenario flag is not activated, the ramp assist function is in a non - activatable state.

[0051] Using the above - mentioned ramp assist control method, when the ramp assist scenario flag of the vehicle is not activated, the ramp assist function cannot be activated, and the anti - rollback can be achieved by controlling the torque of the vehicle motor. There is no limitation on the control method of the motor torque, and the motor torque can be obtained by looking up a table according to the slope information of the current driving road of the vehicle. In specific implementation, the motor torque can be controlled in a closed - loop manner according to the motor speed or according to the vehicle speed.

[0052] Using the above - mentioned ramp assist control method, after the ramp assist function of the vehicle is activated, the vehicle can be prevented from rolling back by controlling the brake to brake.

[0053] As Figure 2 shown, as a specific example, the ramp assist control method includes the following steps:

[0054] S1000: Determine whether the hill-start assist function of the vehicle is in an activatable state. When the hill-start assist function of the vehicle is in an activatable state, execute S2000. When the hill-start assist function of the vehicle is not in an activatable state, execute S3000;

[0055] S2000: Determine whether the hill-start assist function of the vehicle is in an active state. When the hill-start assist function of the vehicle is in an active state, execute S4000. Otherwise, execute S3000;

[0056] S3000: Control the torque of the vehicle's motor to prevent the vehicle from rolling backward;

[0057] S4000: Control the vehicle's brakes to prevent the vehicle from rolling backward.

[0058] As Figure 3 shown, the present invention also provides a hill-start assist control system 10, including an acquisition module 20, a first control module 30, a second control module 40, a determination module 50, and a setting module 60.
