[0027] Embodiment 1

[0028] Figure 1 This is a flow chart of a vehicle control method provided according to the first embodiment of the present invention. This embodiment can be applied to control a vehicle to prevent the vehicle from rolling down a slope. The method can be executed by a vehicle control device, which can be implemented in the form of hardware and / or software. The vehicle control device can be configured in an electronic device. The electronic device in this embodiment can be a vehicle-mounted terminal, a mobile phone, or a tablet computer. Specifically, refer to Figure 1 , the method specifically comprises the following steps:

[0029] Step 110: Obtain the activation state of the target function program of the target vehicle at the current moment, and the target slope of the road surface.

[0030] As we all know, it is very dangerous for a vehicle to roll on a slope, especially when there are vehicles or pedestrians behind in a congested road. Rolling can easily lead to traffic accidents and injuries. Early vehicles were mainly equipped with manual transmissions, and starting on a slope mainly depended on the driver's operating level. Currently, vehicles are basically equipped with automatic transmissions and the automatic parking (AUTOHOLD, AVH) and hill-start assist (HHC) functions in the electronic stability program (ESP). The degree and probability of rolling have been greatly reduced. For AT transmissions equipped with neutral control (N-Control) function, there is a delay in driving force when neutral control is exited. When the automatic parking function is not turned on, there is still a high probability of rolling.

[0031] With the continuous advancement of passenger car technology, in order to improve vehicle drivability and safety, automatic parking function and hill assist function have basically become standard functions of passenger cars. These two functions are currently the main solutions to prevent vehicles from rolling. After the automatic parking function is manually turned on, the wheel end brake will be released only when the driving force after stepping on the accelerator is greater than the rear sliding force, so there will be no problem of rolling. If the automatic parking function is not turned on, the industry standard is that the hill assist function will generally only be automatically activated on a slope greater than 4%, and the function will exit and release the wheel end brake within 2 seconds after releasing the brake. If the driver does not step on the accelerator within 2 seconds, there is a risk of rolling.

[0032] At the same time, vehicles equipped with AT transmissions currently have the neutral gear control function turned on to improve the NVH performance when idling in the forward gear and reduce the noise inside the car, that is, the vehicle enters the neutral gear when the brake is applied to stop the vehicle in the forward gear, and returns to the forward gear to start the vehicle after the brake is released. However, there is a short delay from the neutral gear control function starting to exit to being able to provide driving force, which further increases the risk of the vehicle slipping when the automatic parking function is not turned on.

[0033] For the above working conditions, in the absence of an optimization solution, if you want to completely avoid the vehicle from slipping, you can only rely on the correct and skilled operation of the driver. Through actual vehicle benchmarking, it was found that some vehicles prohibit the activation of the neutral control function on slopes greater than 2% to reduce the risk of slipping. This not only cannot completely solve the problem of slipping, but also leads to the deterioration of NVH performance; some vehicles reduce the risk of slipping by reducing the slope corresponding to the activation of the hill assist function, but this will bring the negative impact of false triggering of the hill assist function on flat roads. After false triggering, the vehicle cannot crawl and start within 2 seconds after releasing the brake. Other solutions include adjusting the torque or applying emergency braking after detecting the occurrence of slipping, which is not a true way to prevent slipping. Based on this, a solution of an embodiment of the present invention is proposed.

[0034] In this embodiment, the target vehicle may be a vehicle traveling on the road, or may be any vehicle parked in a parking lot or on the road, which is not limited in this embodiment.

[0035] In this embodiment, the target function program may be an automatic parking function program or a hill assist function program; the activation state of the target function program may be activated or inactivated, which is not limited in this embodiment.

[0036] In this embodiment, the slope of the road where the target vehicle is located at the current moment can be any slope, for example, 0 degrees, 5 degrees, 10 degrees or 20 degrees, etc., which is not limited in this embodiment.

[0037] It should be noted that, in order to facilitate the explanation of the present invention, the road slope is classified into activation slope, balance slope and maximum slope in this embodiment. The activation slope represents the slope for activating the hill assist function program, which is generally 4% in the industry; the balance slope represents the maximum slope that does not slide down when the vehicle is idle in normal forward gear and the brake is released; the maximum slope represents the maximum slope that does not slide down when the maximum idle torque is in forward gear, and also represents the maximum idle climbing ability.

[0038] It should be noted that the maximum slope can cover the slopes encountered by most users during driving. If an extreme road condition with a slope greater than the maximum slope is encountered, the instrument will remind the driver to manually activate AVH and other operations to avoid sliding down the slope. When the engine torque is determined, the slope balance slope and the maximum slope are calculated based on the vehicle's own parameters, including transmission ratio, transmission efficiency, tire radius and vehicle weight. In most cases, the slope activation slope < balance slope < maximum slope, but depending on the configuration of the vehicle, there may also be a situation where the balance slope < activation slope < maximum slope. In an optional implementation of this embodiment, the activation status of the automatic parking function program or the hill assist function program, as well as the slope of the road where the target vehicle is located at the current moment, can be obtained through ESP.

[0039] Step 120: Determine the oil pressure acting on the clutch according to the activation state and / or the target slope to control the target vehicle.

[0040] In an optional implementation of the present embodiment, after obtaining the activation status of the automatic parking function program or the hill assist function program, and the slope of the road on which the target vehicle is currently located through ESP, the oil pressure acting on the target clutch can be further determined based on the activation status of the target function program, the target slope, or the activation status of the target function program and the target slope, thereby controlling the target vehicle.

[0041] In an optional implementation of the present embodiment, the oil pressure acting on the clutch is determined according to the activation state and / or the target slope to control the target vehicle, which may include: when the activation state of the automatic parking function program is activated, if it is detected that the gear of the target vehicle is switched from a forward gear to a neutral gear, the oil pressure acting on the clutch of the target vehicle is not maintained.

[0042] Optionally, when the vehicle's automatic parking function program is activated, when the transmission enters the neutral control function, it switches from the forward gear to the neutral state, and the oil pressure on the clutch is completely released, which can reduce the engine load to improve NVH performance.

[0043] In another optional implementation of the present embodiment, the oil pressure acting on the clutch is determined according to the activation state and / or the target slope to control the target vehicle, and may also include: when the activation states of the automatic parking function program and the hill assist function program are both inactivated, and the target slope satisfies a first preset slope relationship, maintaining the oil pressure acting on the clutch of the target vehicle; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope satisfies a second preset slope relationship, not maintaining the oil pressure acting on the clutch of the target vehicle; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope satisfies a third preset slope relationship, maintaining the oil pressure acting on the clutch of the target vehicle.

[0044] Among them, the first preset slope relationship is that the target slope is greater than 0 and less than the activation slope or the balance slope; the second preset slope relationship is that the target slope is greater than the activation slope and less than the balance slope; the third preset slope relationship is that the target slope is greater than the balance slope and less than the activation slope.

[0045] Optionally, when the activation states of the automatic parking function program and the hill assist function program are both inactivated, and the target slope is greater than 0 and less than the activation slope or the balance slope, the oil pressure acting on the clutch of the target vehicle is maintained; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope is greater than the activation slope and less than the balance slope, the oil pressure acting on the clutch of the target vehicle is not maintained; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope is greater than the balance slope and less than the activation slope, the oil pressure acting on the clutch of the target vehicle is maintained.

[0046] In another optional implementation of the present embodiment, the oil pressure acting on the clutch is determined according to the activation state and / or the target slope to control the target vehicle, and it may also include: when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope satisfies a fourth preset slope relationship, the oil pressure acting on the clutch of the target vehicle is not maintained, and a torque increase command is sent to the engine control unit to increase the torque of the engine; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope does not satisfy the fourth preset slope relationship, a slope excessive warning is sent to the user.

[0047] Among them, the fourth preset slope relationship is that the target slope is greater than the equilibrium slope and less than the maximum slope.

[0048] Optionally, in this embodiment, when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope is greater than the equilibrium slope and less than the maximum slope, the oil pressure acting on the clutch of the target vehicle is not maintained, and a torque increase command is sent to the engine control unit to increase the torque of the engine; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope is greater than the maximum slope, a slope excessive warning is sent to the user.

[0049] In another optional implementation of the present embodiment, the oil pressure acting on the clutch is determined according to the activation state and / or the target slope to control the target vehicle, and also includes: when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope satisfies a fifth preset slope relationship, the oil pressure acting on the clutch of the target vehicle is not maintained, and a torque increase instruction is sent to the engine control unit to increase the torque of the engine; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope does not satisfy the fifth preset slope relationship, a slope excessive warning is sent to the user to remind the user to brake in time to avoid slipping.

[0050] Among them, the fifth preset slope relationship is that the target slope is greater than the activation slope and less than the maximum slope.

[0051] Optionally, in this embodiment, when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope is greater than the activation slope and less than the maximum slope, the oil pressure acting on the clutch of the target vehicle is not maintained, and a torque increase command is sent to the engine control unit to increase the torque of the engine; when the activation state of the automatic parking function program is inactivated, the activation state of the hill assist function program is activated, and the target slope is greater than the maximum slope, a slope excessive warning is sent to the user to remind the user to brake in time to avoid slipping.

[0052] It is understandable that when the transmission enters the neutral control function, it switches from the forward gear to the neutral state, and the oil pressure on the clutch is completely released, reducing the engine load to improve the NVH performance. In the present invention, the oil pressure during neutral control is determined according to whether the hill assist function program is activated and the current slope. When the hill assist function program is activated, the oil pressure is completely released because the time for the oil pressure to be re-established when the neutral control is exited is lower than the time taken for the hill assist function program to exit, that is, the oil pressure has been rebuilt when the hill assist function program exits. When the hill assist function program is not activated, in order to prevent the vehicle from sliding backward, the power delay time caused by the exit of the neutral control can only be shortened. On the one hand, the brake pressure needs to be stepped on, which has little effect on NVH; on the other hand, the speed of re-building pressure after releasing the brake is adjusted. When the hill assist function program is not activated, the greater the slope, the faster the pressure building speed. This scheme is called fast pressure building, but too fast pressure building speed will cause the vehicle to shake. On a flat road, the pressure building speed is set according to comfort. The above two solutions for shortening the power delay time should be coordinated with each other and calibrated according to the actual vehicle performance to achieve the effect of preventing the vehicle from slipping and avoid other negative effects. When the slope is too steep, after the hill assist function program is activated, the output torque of the engine is mainly used to ensure that the vehicle does not slip. The required torque increases with the increase of the slope. After releasing the brake, the transmission sends a corresponding torque increase value. The engine responds to the torque increase and the vehicle does not slip after the hill assist function program is exited.

[0053] It should be noted that, in this embodiment, the actions of maintaining or not maintaining the oil pressure on the clutch of the target vehicle and the excessive slope warning are all performed when the driver steps on the brake to stop the vehicle; and the torque increase command sent to the engine control unit is triggered when the driver releases the brake. It should also be noted that the clutch builds up oil pressure, which refers to the process of the clutch oil pressure rising to the target value after the brake is released, with or without maintaining the oil pressure; the speed of the oil pressure rise is adjustable, not fixed, that is, the pressure can be built up quickly, or it can be built up comfortably, that is, the pressure can be reduced slowly, which is not limited in this embodiment.

[0054] The technical solution of this embodiment obtains the activation state of the target function program of the target vehicle at the current moment, and the target slope of the road on which it is located; determines the oil pressure acting on the clutch according to the activation state and / or the target slope to control the target vehicle, thereby solving the problem of vehicles easily slipping on slopes and causing traffic accidents, while also ensuring the overall performance of the vehicle to the greatest extent without causing other negative effects.

[0055] In order to better understand the embodiments of the present invention, Figure 2 is a schematic diagram of the interaction relationship between controllers provided according to the first embodiment of the present invention, with reference to Figure 2, which mainly includes: a transmission control unit 210, an engine control unit 220, a vehicle body electronic document system 230 and a meter 240;

[0056] Among them, the transmission control unit 210 can receive the activation status of the automatic parking function program, the activation status of the hill assist function program and the road slope generated by the vehicle body electronic document system 230; it can also receive the transmitter torque parameters sent by the engine control unit 220; further, the transmission control unit 210 can send a torque increase instruction to the engine control unit 220 based on the received information. When the slope is too large, it can send a slope excessive warning to the instrument 240 to remind the driver to brake in time.

[0057] Figure 3 is a flow chart of a vehicle control method provided according to the first embodiment of the present invention. In this example, the activation slope < the balance slope < the maximum slope. For details, refer to Figure 3 , which mainly includes the following steps:

[0058] Step 310: Whether the automatic parking function program is activated;

[0059] If so, the pressure will not be maintained, but built up comfortably;

[0060] Otherwise, execute step 320.

[0061] Step 320: Whether the ramp assist function program is not activated, and 0<slope<activation slope;

[0062] If so, maintain the pressure and build up the pressure quickly;

[0063] Otherwise, execute step 330.

[0064] Step 330: Whether the ramp assist function program is activated, and the activation slope < slope < balance slope;

[0065] If so, the pressure will not be maintained, but built up comfortably;

[0066] Otherwise, execute step 340.

[0067] Step 340: Whether the ramp assist function program is activated, and the balance slope < slope < maximum slope;

[0068] If so, the pressure is not maintained, the pressure is comfortably built up and a torque increase request is sent to the engine;

[0069] Otherwise, a warning will be given if the slope is too large.

[0070] Figure 4 is a flow chart of a vehicle control method provided according to the first embodiment of the present invention; in this example, the balance slope < activation slope < maximum slope, for details, refer to Figure 4, which mainly includes the following steps:

[0071] Step 410: Whether the automatic parking function program is activated;

[0072] If so, the pressure will not be maintained, but built up comfortably;

[0073] Otherwise, execute step 420.

[0074] Step 420: Whether the hill assist function program is not activated, and 0<slope<balance slope;

[0075] If so, maintain the pressure and build up the pressure quickly;

[0076] Otherwise, execute step 430.

[0077] Step 430: Whether the ramp assist function program is not activated, and the balance slope < slope < activation slope;

[0078] If yes, the pressure is maintained, the pressure is quickly built up and a torque increase request is sent to the engine;

[0079] Otherwise, execute step 440.

[0080] Step 440: Whether the ramp assist function program is activated, and the activation slope < slope < maximum slope;

[0081] If so, the pressure is not maintained, the pressure is comfortably built up and a torque increase request is sent to the engine;

[0082] Otherwise, a warning will be given if the slope is too large.

[0083] The solution of the embodiment of the present invention not only ensures the normal use of the neutral control function on a slope, improves NVH performance and idle fuel consumption, but also avoids the problem of sliding down the slope when starting on a slope, thereby improving the driving safety factor of the vehicle itself.

[0084] In the technical solution of the embodiment of the present invention, the acquisition, storage and application of user personal information (such as facial information, voice information, etc.) are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.
