Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional technique, since the anti-slip agent is sprayed in response to a switch operation by the driver, the anti-slip agent is not sprayed until the driver notices the slip of the vehicle and operates the switch. For example, when a vehicle stops on a frozen slope, the vehicle may slide down the road surface due to its own weight and slip. Therefore, when slip occurs in a state where the vehicle has stopped on a frozen slope, there is a risk that the moving distance due to the slip becomes long.

[0005] The present invention has been made in view of the above, and an object thereof is to shorten the moving distance due to slip when slip occurs in a state where the vehicle has stopped on a frozen slope.

Means for Solving the Problems

[0006] An information processing device according to one embodiment includes a controller. The controller detects the vehicle's stationary state based on the vehicle's driving information and detects slippage in the stationary vehicle. If slippage is detected, the controller instructs the vehicle to activate the slip suppression device. [Effects of the Invention]

[0007] The information processing device according to this embodiment can activate the slip suppression device in response to a slip, by instructing the vehicle to activate the slip suppression device when a slip is detected while the vehicle is stationary, based on the vehicle's driving information. Therefore, the vehicle can shorten the distance traveled due to the slip, for example, when a slip occurs from a stationary state on a frozen slope. [Brief explanation of the drawing]

[Figure 6] Figure 6 shows an example of a monitor display installed in another vehicle. [Modes for carrying out the invention]

[0009] The information processing device, vehicle control device, and control method according to the embodiment will be described in detail below with reference to the attached drawings. However, this embodiment is not the sole limiting factor of the present invention.

[0010] As shown in Figure 1, the information processing system 1 according to this embodiment comprises a vehicle control device 2 and an information processing device 3. Figure 1 is a block diagram illustrating the information processing system 1 according to this embodiment.

[0011] The vehicle control device 2 and the information processing device 3 are connected via a network N, such as the Internet, to enable communication. The information processing device 3 is, for example, a server device. The information processing device 3 is also connected via the network N to enable communication with other information processing devices.

[0012] The vehicle control device 2 is installed in the vehicle 100. The vehicle control device 2 activates the slip suppression device 4.

[0013] The slip suppression device 4 performs at least one of the following: spraying a slip suppressant and discharging a slip suppression member. The slip suppressant includes sand and de-icing agents. When the slip suppression device 4 sprays a slip suppressant, it sprays the slip suppressant in front of the wheels. The slip suppression member includes tire nets and chains. When the slip suppression device 4 discharges a tire net, it automatically wraps the tire net around the wheel, for example. The slip suppression device 4 may also deploy the tire net in front of the wheel.

[0014] Vehicle 100 can be stopped by the slip suppression device 4, even if it slips, for example, when the slip suppression device 4 is activated.

[0015] Next, the vehicle control device 2 according to the embodiment will be described with reference to Figure 2. Figure 2 is a block diagram illustrating the vehicle control device 2 according to the embodiment.

[0016] The vehicle control device 2 comprises a communication unit 10, a storage unit 11, and a controller 12. The communication unit 10 is a communication interface that transmits and receives information with the information processing device 3.

[0017] The storage unit 11 is realized by a storage device such as a ROM (Read Only Memory), a RAM (Random Access Memory), a flash memory, etc. Various data and various programs are stored in the storage unit 11.

[0018] The controller 12 corresponds to a so-called processor. The controller 12 is realized by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphical Processing Unit), etc. The controller 12 executes the program according to the illustrated exemplary embodiment stored in the storage unit 11, using the RAM as a working area. Also, the controller 12 can be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0019] The controller 12 is connected to the sensor group 20, the camera 21, and the slip suppression device 4.

[0020] The sensor group 20 includes a plurality of sensors that detect driving information. The sensor group 20 includes a vehicle speed sensor, a GNSS (Global Navigation Satellite System) sensor, a brake sensor, an inclination sensor, an illuminance sensor, and a temperature sensor, etc.

[0021] The vehicle speed sensor detects the vehicle speed of the vehicle 100 from the rotational speed of the wheels of the vehicle 100. The GNSS sensor detects the current position of the vehicle 100 based on the signal received from the artificial satellite. The brake sensor detects the operating state of the brake device of the vehicle 100. For example, when the brake device is operating, the brake sensor becomes "ON". When the brake device is not operating, the brake sensor becomes "OFF".

[0022] The tilt sensor detects the inclination of the vehicle 100, that is, the inclination of the road surface on which the vehicle 100 is traveling or the road surface on which it is parked. The tilt sensor is, for example, a G-sensor. The illuminance sensor detects the illuminance outside the vehicle. The temperature sensor detects the temperature outside the vehicle.

[0023] Camera 21 may be installed to capture images of the front of the vehicle 100, for example. Camera 21 may also be installed to capture images of the rear of the vehicle 100, the sides of the vehicle 100, etc. Multiple cameras 21 may be installed.

[0024] The controller 12 activates the slip suppression device 4 when it detects a slip in the stationary vehicle 100. Specifically, the controller 12 activates the slip suppression device 4 when it detects a slip in the stationary vehicle 100 on an icy ramp. In other words, if the stationary vehicle 100 on an icy ramp slides down, the controller 12 activates the slip suppression device 4 to stop the vehicle 100.

[0025] Next, the information processing device 3 according to the embodiment will be described with reference to Figure 3. Figure 3 is a block diagram illustrating the information processing device 3 according to the embodiment.

[0026] The information processing device 3 comprises a communication unit 30, a storage unit 31, and a controller 32. The communication unit 30 is a communication interface that transmits and receives information with the vehicle control device 2. The communication unit 30 can also transmit and receive information with other information processing devices 3.

[0027] The memory unit 31 is implemented by a storage device such as ROM, RAM, or flash memory. Various data and various programs are stored in the memory unit 31.

[0028] The controller 32 corresponds to a so-called processor. The controller 32 is implemented by a CPU, MPU, GPU, etc. The controller 32 executes a program according to an embodiment not shown, stored in the memory unit 31, using RAM as the working area. The controller 32 can also be implemented by an integrated circuit such as an ASIC or FPGA.

[0029] The controller 32 instructs the vehicle 100 to operate if it detects a slip in the stationary vehicle 100. Specifically, if the controller 32 detects a slip in the vehicle 100 while it is stationary on an icy ramp, it instructs the vehicle 100 to operate the slip suppression device 4.

[0030] Next, the slip response processing according to the embodiment will be described with reference to Figures 4 and 5. The slip response processing includes slip suppression processing and slip suppression instruction processing. Figure 4 is a flowchart illustrating the slip suppression processing performed by the vehicle control device 2. Figure 5 is a flowchart illustrating the slip suppression instruction processing performed by the information processing device 3.

[0031] First, we will explain the slip suppression process performed by the vehicle control device 2.

[0032] The controller 12 of the vehicle control device 2 acquires driving information of the vehicle 100 (S100). The driving information of the vehicle 100 includes the speed information of the vehicle 100, the position information of the vehicle 100, the operation information of the brake system on the vehicle 100, the tilt information of the vehicle 100, and the outside temperature information. The driving information of the vehicle 100 is detected by the sensor group 20. The controller 12 can acquire various information from the sensor group 20 for determining slip.

[0033] Next, the controller 12 transmits the location information of the vehicle 100 to the information processing device 3 (S101). Next, the controller 12 determines whether or not it has received freezing information from the information processing device 3 (S102). Freezing information is information about roads that are likely to freeze. For example, freezing information is map data of roads that are likely to freeze. Freezing information may also be map data of roads that are likely to freeze in the area where the vehicle 100 is traveling.

[0034] If the controller 12 has not received freeze information from the information processing device 3 (S102: No), it repeats the process in step S102.

[0035] When the controller 12 receives freezing information from the information processing device 3 (S102: Yes), it determines, based on the driving information, whether or not it has detected a slip in the vehicle 100 that is stationary on the frozen ramp (S103). Specifically, the controller 12 determines, based on the freezing information and the driving information, whether or not it has detected a slip in the vehicle 100 that is stationary on the frozen ramp. The controller 12 determines whether or not a slip has occurred in the vehicle 100 that is stationary on the frozen ramp and is sliding down due to its own weight.

[0036] The controller 12 determines whether the road surface is frozen based on freezing information, the location information of the vehicle 100, and the outside temperature. The controller 12 determines that the road surface is frozen if the area in which the vehicle 100 is traveling has a possibility of freezing according to the freezing information, and the outside temperature is below a predetermined temperature. The predetermined temperature is a temperature set in advance. For example, the predetermined temperature is 0 degrees. However, the predetermined temperature may be higher than 0 degrees. For example, the predetermined temperature may be 3 degrees or 5 degrees.

[0037] The controller 12 can accurately determine whether the road surface is frozen by determining whether or not it is frozen based on freezing information, the location information of the vehicle 100, and the outside temperature.

[0038] The controller 12 determines that the road is an incline if the inclination of the vehicle 100 is greater than or equal to a predetermined incline. The predetermined incline is set in advance. The predetermined incline is, for example, the incline at which a slip will occur on an icy road surface, where the vehicle 100 will slide down due to its own weight.

[0039] Furthermore, the controller 12 determines that the vehicle 100 is stationary when the brakes are applied and the vehicle speed is zero. In other words, the controller 12 detects that the vehicle 100 is stationary when the brakes are applied and the vehicle speed is zero. The controller 12 determines whether the vehicle 100 has moved based on the vehicle's position information. If the controller 12 determines that the vehicle 100 is stationary and has moved based on the vehicle's position information, it determines that the vehicle 100 has moved against the driver's intention to stop.

[0040] The controller 12 detects a slip if the stationary vehicle 100 is moving on an icy ramp, determining that the vehicle 100 is sliding down the ramp due to its own weight and that a slip has occurred. In other words, the controller 12 detects a slip in the stationary vehicle 100.

[0041] Based on freezing information and driving information, the controller 12 can accurately detect slippage of the vehicle 100 while it is stationary on an icy slope.

[0042] The controller 12 terminates the current process if it does not detect a slip in the vehicle 100 which is stationary on an icy ramp (S103: No). For example, the controller 12 terminates the current process if it determines that the road surface of the road on which the vehicle 100 is traveling is not icy. The controller 12 terminates the current process if it determines that the road on which the vehicle 100 is traveling is not an ramp. The controller 12 terminates the current process if it determines that the vehicle 100 is not stationary. The controller 12 terminates the current process if the vehicle 100 is not moving.

[0043] If the controller 12 detects a slip in the vehicle 100 while it is stationary on an icy slope (S103: Yes), it transmits the vehicle's driving information to the information processing device 3 (S104). By transmitting the vehicle's driving information to the information processing device 3, the vehicle control device 2 and the information processing device 3 can share the vehicle's driving information.

[0044] Next, the controller 12 determines whether or not it has received an operation instruction from the information processing device 3 (S105). The operation instruction is an instruction signal to activate the slip suppression device 4. Specifically, the controller 12 determines whether or not it has received an operation instruction within a first predetermined time after transmitting the vehicle 100's driving information. The first predetermined time is a time set in advance. The first predetermined time is, for example, the time required for the information processing device 3 to perform slip detection, which will be described later. If the controller 12 does not receive an operation instruction (S105: No), it terminates the current process.

[0045] When the controller 12 receives an operation instruction (S105: Yes), it activates the slip suppression device 4 (S106).

[0046] The controller 12 can stabilize the slip that occurs by activating the slip suppression device 4 according to the operation instructions. In other words, by activating the slip suppression device 4 according to the operation instructions, the controller 12 can quickly activate the slip suppression device 4, thereby shortening the distance the vehicle 100 travels due to the slip.

[0047] The controller 12 may also notify the driver of information regarding the operation of the slip suppression device 4 based on the operation instruction. The slip suppression device 4 may also be activated by the driver's operation.

[0048] Next, the controller 12 acquires the position information of the vehicle 100 (S107). Next, the controller 12 determines whether the vehicle 100, which has moved due to slippage, has come to a stop (S108). Specifically, the controller 12 determines whether the vehicle 100 has come to a stop based on the position information of the vehicle 100.

[0049] If the vehicle 100 is not stopped (S108: No), the controller 12 returns to step S107 and repeats the above process.

[0050] If the vehicle 100 stops (S108: Yes), the controller 12 transmits the vehicle 100's stop information to the information processing device 3 (S109). This allows the vehicle control device 2 and the information processing device 3 to share the stop information.

[0051] Next, the slip suppression instruction process executed by the information processing device 3 will be explained using Figure 5.

[0052] The controller 32 of the information processing device 3 determines whether or not it has acquired the location information of the vehicle 100 from the vehicle control device 2 (S200). If the controller 32 has not acquired the location information of the vehicle 100 (S200: No), it terminates the current process.

[0053] When the controller 32 obtains location information of the vehicle 100 (S200: Yes), it obtains weather information and road surface information (S201). The controller 32 obtains weather information and road surface information from other information processing devices 3. The controller 32 obtains weather information for the area in which the vehicle 100 is traveling, and road surface information for the roads in the area in which the vehicle 100 is traveling. The controller 32 may obtain at least one of the weather information and road surface information. Weather information includes information such as weather and temperature. Road surface information includes information such as snow cover and ice. By obtaining weather information and road surface information, the controller 32 can narrow down the areas where road surfaces are frozen.

[0054] Controller 32 generates freezing information (S202). Controller 32 generates freezing information based on weather information and road surface information. For example, if the weather is snowy, the temperature is below 0 degrees Celsius, and there is snow cover, Controller 32 determines that the road surface may freeze. Then, Controller 32 generates freezing information indicating that the road surface may freeze.

[0055] Furthermore, for example, if the weather in the area where the vehicle 100 is traveling is sunny, the temperature is above 0 degrees Celsius, and there is no snow cover, the controller 32 determines that the road surface in the area where the vehicle 100 is traveling will not freeze. The controller 32 then generates freezing information indicating that the road surface will not freeze.

[0056] Next, the controller 32 transmits the freezing information to the vehicle control device 2 (S203). By transmitting the freezing information to the vehicle control device 2, the vehicle control device 2 and the information processing device 3 can share the freezing information. Based on the freezing information, the controller 32 can accurately determine whether the road surface is frozen.

[0057] Next, the controller 32 determines whether or not it has received driving information for vehicle 100 from the vehicle control device 2 (S204). Specifically, the controller 32 determines whether or not it has received driving information for vehicle 100 within a second predetermined time after transmitting the freezing information. The second predetermined time is set in advance. The second predetermined time is, for example, the time required for the vehicle control device 2 to detect slippage. If the controller 32 does not receive driving information for vehicle 100 (S204: No), it terminates the current process.

[0058] When the controller 32 receives driving information from the vehicle 100 (S204: Yes), it determines, based on the driving information from the vehicle 100, whether or not it has detected a slip of the vehicle 100 while it is stationary on an icy slope (S205). The controller 32 detects a slip of the vehicle 100 while it is stationary on an icy slope based on the driving information from the vehicle 100.

[0059] Specifically, the controller 32 detects slippage of the stationary vehicle 100 on an icy slope based on weather information for the area in which the vehicle 100 is traveling, road surface information for the road on which the vehicle 100 is traveling, and vehicle 100's driving information. The method for detecting slippage is the same as the method for detecting slippage in the vehicle control device 2, and a detailed explanation is omitted. The controller 32 also performs slippage detection on the information processing device 3 side.

[0060] The controller 32 can accurately determine when the vehicle 100 is stopped based on the vehicle's speed information and the operation information of the vehicle's brake system. The controller 32 can accurately determine when the vehicle 100 is moving while stopped based on the vehicle's position information. The controller 32 can accurately determine the slope of the road surface on which the vehicle 100 is stopped based on the vehicle's inclination information. The controller 32 can accurately determine whether the road surface is frozen based on the outside temperature information. Therefore, the controller 32 can accurately detect when a vehicle 100 is stopped on a frozen slope.

[0061] The controller 32 can accurately determine whether the road surface is frozen based on weather information for the area in which the vehicle 100 is traveling, road surface information for the road on which the vehicle 100 is traveling, and outside temperature information. Therefore, the controller 32 can accurately detect when a vehicle 100 is stationary on an icy slope and slips.

[0062] If the controller 32 does not detect any slippage of the stationary vehicle 100 on the frozen ramp (S205: No), it terminates the current process.

[0063] If the controller 32 detects that the vehicle 100 is stationary on an icy ramp, it transmits an instruction to the vehicle control device 2 to activate the slip suppression device 4 (S206). In other words, if the controller 32 detects that the vehicle 100 is stationary on an icy ramp, it instructs the vehicle 100 to activate the slip suppression device 4.

[0064] As a result, the slip suppression device 4 is activated in vehicle 100. Therefore, if a slip occurs in vehicle 100 while it is stationary on an icy slope, the controller 32 can quickly activate the slip suppression device 4. Consequently, the controller 32 can shorten the distance traveled by vehicle 100 due to the slip.

[0065] Next, the controller 32 determines whether or not it has received stop information from the vehicle control device 2 (S207). If the controller 32 does not receive stop information (S207: No), it repeats the process in step S207 until it receives stop information.

[0066] If the controller 32 receives stop information (S207: Yes), it transmits slip warning information to other vehicles traveling in the area where vehicle 100 is traveling (S208). In other words, if vehicle 100 stops slipping due to the operation of the slip suppression device 4, the controller 32 notifies other vehicles traveling in the area where vehicle 100 is traveling of slip warning information.

[0067] This allows the controller 32 to alert other vehicles traveling in the area where the vehicle 100, which has detected a slip, is traveling, about the occurrence of a slip. For example, in other vehicles, a warning about the occurrence of a slip is displayed on the monitor 200, as shown in Figure 6. Figure 6 is a diagram showing an example of the display on the monitor 200 installed in another vehicle. The monitor 200 is installed, for example, in a navigation system and a drive recorder. The monitor 200 may also be a monitor of a terminal device such as a smartphone. The warning may also be given by outputting an audible message. Drivers of other vehicles can suppress the occurrence of a slip by, for example, attaching chains or the like to their wheels in advance.

[0068] Next, a modified version will be described. In the modified version, the information processing system may detect slippage in a vehicle 100 that is stationary on an icy ramp using either the vehicle control device 2 or the information processing device 3.

[0069] The driving information of vehicle 100 may further include at least one of external illumination information and external image information.

[0070] For example, at least one of controllers 12 and 32 may determine whether or not the road surface is frozen based on the illuminance outside the vehicle. For example, if the road is in the shade and the illuminance is low, the temperature of the road surface will be low, making it more likely to freeze. For example, if controller 32 is lower than a predetermined illuminance, it raises a predetermined temperature. Controller 32 sets a predetermined temperature based on the illuminance outside the vehicle and determines whether or not the road surface is frozen based on the freezing information and the temperature outside the vehicle.

[0071] For example, the controller 32 can accurately determine whether the road surface is frozen by determining whether or not it is frozen based on the illumination outside the vehicle.

[0072] Furthermore, at least one of controllers 12 and 32 may determine whether or not the road surface is frozen based on external image information. For example, controller 32 may determine whether or not the road surface is frozen by performing predetermined image processing on external image data captured by camera 21.

[0073] For example, the controller 32 can accurately determine whether the road surface is frozen by determining whether or not it is frozen based on image information from outside the vehicle.

[0074] Furthermore, the controller 32 may predict, for example, an icy slope based on the driving information of the vehicle 100 while it is in motion. Then, for example, the controller 32 instructs the vehicle 100 to activate the slip suppression device 4 before the vehicle 100 travels on an icy slope where icing is predicted.

[0075] The controller 32 predicts whether the ramp surface is frozen based, for example, on the location information of the vehicle 100 and the freezing information. The controller 32 may further predict whether the ramp surface is frozen by making the following determinations.

[0076] For example, the controller 32 determines whether it is morning, noon, night, before sunrise, or before sunset based on time information acquired by the GNSS sensor. The controller 32 also detects the surrounding environmental conditions of the vehicle 100 based on external image information and determines whether the vehicle 100 is traveling in mountainous areas, in sunlight, in shade, or on a bridge. The controller 32 also determines, for example, whether the vehicle 100 has entered or left the shade based on changes in outside temperature. Furthermore, the controller 32 may acquire road congestion information from other information processing devices and predict, for example, road surface freezing on roads that bypass congested roads. The controller 32 may also use these determinations to predict slopes with frozen road surfaces.

[0077] Furthermore, for example, the controller 12 may classify the level of slippage of the vehicle 100 on an icy slope based on the vehicle 100's driving information.

[0078] For example, the controller 12 sets the vehicle 100 to level "1" if the inclination of the vehicle 100 is less than a predetermined inclination, or if the outside temperature is above a first predetermined temperature. The first predetermined temperature is a preset temperature at which the road surface does not freeze.

[0079] Furthermore, the controller 12 sets the vehicle 100 to level "2" if the inclination of the vehicle 100 is greater than a predetermined inclination and the outside temperature is greater than or equal to the second predetermined temperature but less than the first predetermined temperature, indicating that there is a risk of the vehicle 100, which is stopped on the ramp, slipping due to its own weight. The second predetermined temperature is a preset temperature that is lower than the first predetermined temperature.

[0080] Furthermore, the controller 12 sets the vehicle 100 to level "3" if the inclination of the vehicle 100 is greater than a predetermined inclination and the outside temperature is below the second predetermined temperature, indicating a high probability that the vehicle 100 parked on the ramp will slip due to its own weight.

[0081] For example, if the level is "3", the controller 12 will activate the slip suppression device 4 even if the vehicle 100 is not moving. However, the conditions corresponding to the levels are not limited to the above conditions. Alternatively, the controller 32 may perform level classification, and for example, if the level is "3", it may instruct the operation of the slip suppression device 4 even if the vehicle 100 is not slipping.

[0082] Furthermore, for example, even if no slip is occurring in the vehicle 100, the controller 12 may classify the driving information into levels according to the types of driving information that satisfy the conditions that affect the vehicle 100's slip on the icy slope. The more types of driving information that satisfy the conditions that affect the vehicle 100's slip on the icy slope, the higher the level. For example, the more types of driving information that satisfy the conditions that affect the vehicle 100's slip on the icy slope, the higher the level will be in the order of "1", "2", and "3". For example, if the level is "2", the controller 12 will issue a warning to the driver regarding the occurrence of slip, even if the vehicle 100 is not slipping. For example, if the level is "3", the controller 12 will activate the slip suppression device 4, even if the vehicle 100 is not slipping.

[0083] Further effects and modifications can be readily derived by those skilled in the art. Therefore, broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and their equivalents.
