Description

Technical Field

[0002] With the continuous development of economy and science and technology, cars are no longer just a means of transportation for people, but a popular product integrated with cutting-edge technologies. In order to bring users more driving pleasure and technological experience, the All Terrain System (ATS) developed based on various scenarios came into being.

[0003] The ATS system is an electronic control system for a car. When driving a car equipped with an all-terrain control system, the driver can select the corresponding terrain mode according to the actual terrain conditions of the car, such as snow, sand, mud, etc., so that the various subsystems of the car enter the working mode corresponding to the terrain mode. At this time, each subsystem can maximize the stability and safety of the car under the terrain conditions.

[0004] At present, the ATS system is mainly used in fuel vehicles and pure electric vehicles. Although some hybrid vehicles on the market have been equipped with the ATS system, such as snow mode, mud mode, and sand mode, the early software architecture mainly focused on the interaction between the ATS system and the electronic steering power system, making it incompatible with hybrid vehicles of various architectures. As a result, when hybrid vehicles are equipped with existing ATS, they need to redesign the software, resulting in unnecessary waste of resources and costs, which is not conducive to the rapid iteration of software.

[0040] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The all-terrain control method of the present invention is based on the all-terrain control system on the hybrid vehicle, which includes an ATS (All Terrain System) module, a HUT (Head Unit System) module and an HCU (Hybrid Control Unit) module, and the ATS module is connected to the HUT module and the HCU module via a CAN bus. The user manually switches the all-terrain mode by operating the switch of the ATS module, and manually switches the vehicle's driving mode by operating the switch of the HUT module. The user can also automatically switch the all-terrain mode or the driving mode through the corresponding relationship between the ATS module and the HCU mode.

[0042] Figure 1 A flow chart of an all-terrain control method according to an embodiment of the present application is shown. Figure 1 The method is applied to a hybrid vehicle equipped with an ATS module, and the method comprises:

[0043] Step S101, monitoring the all-terrain mode of the vehicle and monitoring the driving mode of the vehicle;

[0044] Regarding the execution subject of the embodiment of the present invention, it can be various controllers or processors suitable for configuration in the vehicle. For example, on the one hand, the controller or processor of the vehicle itself can be improved by corresponding hardware and software to implement the vehicle terrain mode control method in the embodiment of the present invention; on the other hand, it can also be a processor or controller additionally configured on the vehicle to implement the vehicle terrain mode control method as described in this application, and the above implementation modes all fall within the protection scope of the present invention.

[0045] Specifically, in an embodiment of the present invention, the all-terrain control device monitors the all-terrain mode (all-terrain mode signal) of the vehicle in real time; the all-terrain modes of the vehicle include: standard mode, economy mode, sports mode, snow mode, mud mode, sand mode, 4L mode, rock mode, mountain mode, bumpy road mode and mud and sand mode, and each mode can achieve different effects.

[0046] Specifically, standard mode (Standard): This mode takes into account both the power and economy of the vehicle, and the driving style of the vehicle is relatively conventional; economic mode (ECO): This mode improves the vehicle's fuel economy and is suitable for flat and hard roads such as urban roads and paved roads. Sport mode: In this mode, the accelerator pedal is sensitive, the transmission delays shifting, the vehicle's power is increased, and the driving style of the whole vehicle tends to be intense; Snow mode: This mode is mainly used for driving under low adhesion coefficient conditions or off-road driving, and the main roads used include snow, ice, grass, gravel roads, etc.; Mud mode: This mode is mainly used for driving in deep and shallow mud or off-road driving; Sand mode: This mode is mainly used for driving in deserts and Gobi or off-road driving; 4L mode: This mode is mainly used for low-speed escape conditions (such as climbing conditions, stuck conditions), and conditions that require high torque for climbing; Rock mode: This mode is mainly used for climbing wet or dry hard roads; Mountain mode: This mode is mainly used for mountain road driving; Pothole mode: This mode is mainly used for uneven roads; Mud_Sand mode: This mode is mainly used for muddy and deep groove roads with sand.

[0047] It should be noted that in Sport mode, Snow mode, Mud mode, Sand mode, 4L mode, Rock mode, Mountain mode, Pothole mode and Mud_Sand mode, the vehicle's four-wheel drive system is in a low gear (that is, the four-wheel drive system is in 4L mode), at which time it can output large torque.

[0048] Specifically, in the embodiment of the present invention, the all-terrain control device monitors the driving mode (driving mode signal) of the vehicle in real time, and the driving modes of the vehicle include: pure electric mode (EV), energy-saving mode (Save) and hybrid mode (HEV). Among them, EV mode: in this mode, the motor provides power and the engine does not work; SAVE mode: in this mode, when the battery power is greater than a certain value, the motor provides power; when the battery power is less than a certain value, the generator charges the battery; when a large torque is required, the engine and the motor jointly provide power; HEV mode: in this mode, the motor and the engine jointly provide power.

[0049] Step S102: when a change in the all-terrain mode of the vehicle is detected, based on the correspondence between the all-terrain mode and the driving mode, the driving mode of the vehicle is controlled using the changed all-terrain mode, wherein the change in the all-terrain mode of the vehicle is triggered by a switch of the ATS module;

[0050] Table 1 shows a control strategy of an all-terrain control system according to an embodiment of the present invention. As can be seen from Table 1, in Standard mode and ECO mode, the driving mode of the vehicle is any one of EV mode, SAVE mode and HEV mode; in Sport mode, Snow mode, Mud mode, Sand mode, 4L mode, Rock mode, Mountain mode, Pothole mode and Mud_Sand mode, the driving mode of the vehicle is HEV mode.

[0051] Table 1 Control strategy of an all-terrain control system

[0052]

[0053]

[0054] Specifically, when the all-terrain control device detects that the all-terrain mode of the vehicle has changed, such as switching the all-terrain mode from Standard mode to Mud mode through the switch of the ATS module, based on the correspondence between the all-terrain mode and the driving mode, the HCU module will automatically switch the driving mode to HEV mode.

[0055] Step S103: When a change in the driving mode of the vehicle is detected, based on the correspondence between the driving mode and the all-terrain mode, the all-terrain mode of the vehicle is controlled using the changed driving mode, wherein the change in the driving mode of the vehicle is triggered by a switch of the HUT module.

[0056] Specifically, when the all-terrain control device detects a change in the vehicle's driving mode, such as switching the HEV mode to the EV mode through the switch of the HUT module, the ATS module will automatically switch the all-terrain mode to the standard mode based on the correspondence between the all-terrain mode and the driving mode.

[0057] Compared with the prior art, the present application performs closed-loop control of the vehicle's driving mode and the all-terrain mode by real-time monitoring of the vehicle's all-terrain mode and driving mode, and by the correspondence between the vehicle's driving mode and the all-terrain mode. When the vehicle's all-terrain mode changes, the vehicle's driving mode will automatically respond to the change in the all-terrain mode; when the vehicle's driving mode changes, the all-terrain mode will automatically respond to the change in the driving mode. According to the above technical solution, the autonomous selection and switching of the all-terrain mode and the driving mode can be achieved, the driving mode switching function of the all-terrain control system is expanded, and the gap in driving mode control when the existing all-terrain control system is applied to hybrid vehicles is made up, so that the all-terrain control system can be compatible with hybrid vehicles of various architectures.

[0058] In an optional embodiment, in step S102, when it is detected that the all-terrain mode of the vehicle changes, based on the correspondence between the all-terrain mode and the driving mode, controlling the driving mode of the vehicle using the changed all-terrain mode includes:

[0059] Step S1021: When the all-terrain mode after the change is the standard mode or the economic mode, the driving mode of the vehicle is maintained;

[0060] Step S1022: When the changed all-terrain mode is other modes, switch the driving mode of the vehicle to the hybrid mode; wherein the other modes are modes in the all-terrain mode except the standard mode and the economy mode.

[0061] Specifically, in an embodiment of the present invention, when the all-terrain mode of the vehicle changes, the driving mode will respond to the change of the all-terrain mode. When the all-terrain control device detects that the all-terrain mode has changed, if the all-terrain mode after the change is the Standard mode or the ECO mode, in the Standard mode or the ECO mode, the vehicle can work in any driving mode, therefore, the HCU module will not switch the driving mode of the vehicle, that is, the driving mode of the vehicle remains unchanged. If the all-terrain mode after the change is the Sport mode or the Snow mode or the Mud mode or the Sand mode or the 4L mode or the Rock mode or the Mountain mode or the Pothole mode or the Mud_Sand mode, since these modes can only work normally in the HEV mode, therefore, the HCU module needs to switch the driving mode of the vehicle to the HEV mode. For example, when the all-terrain mode is switched from the 4L mode to the ECO mode, the driving mode of the vehicle remains unchanged.

[0062] In an optional embodiment, in step S103, when a change in the driving mode of the vehicle is detected, based on the correspondence between the driving mode and the all-terrain mode, controlling the all-terrain mode of the vehicle using the changed driving mode includes:

[0063] Step S1031: When the changed driving mode is the hybrid mode, maintaining the all-terrain mode of the vehicle;

[0064] Step S1032: When the changed driving mode is the pure electric mode or the energy-saving mode, the all-terrain mode of the vehicle is switched to the standard mode, and a prompt is given to exit the 4L mode of the four-wheel drive system.

[0065] Specifically, in an embodiment of the present invention, when the driving mode of the vehicle changes, the all-terrain mode will respond to the change in the driving mode. When the all-terrain control device detects that the driving mode of the vehicle has changed, if the changed driving mode is the HEV mode, since the HEV mode is suitable for all all-terrain modes, the ATS module will not automatically switch the all-terrain mode of the vehicle. When the changed driving mode is the EV mode or the Save mode, since the terrain mode corresponding to the EV mode or the Save mode is the Standard mode or the ECO mode, the ATS module automatically switches the all-terrain mode to the Standard mode or the ECO mode. Since the output of the ATS module must be a certain result when the all-terrain mode is automatically switched using the ATS module, in an embodiment of the present invention, when the changed driving mode is the Standard mode or the ECO mode, the ATS module automatically switches the all-terrain mode to the Standard mode. In the Standard mode, it is not necessary to output a large torque, so the all-terrain control device will remind the user to exit the 4L mode of the four-wheel drive system.

[0066] In an optional embodiment, the all-terrain control method further includes:

[0067] Step S104: When the all-terrain mode of the vehicle does not change, the driving mode of the vehicle is controlled based on a switching request of the user, and the switching request of the user is triggered by a switch of the HUT module.

[0068] In the embodiment of the present invention, in addition to switching the driving mode of the vehicle based on the change of the all-terrain mode, the user can also manually select the driving mode through the switch on the HUT module to switch the driving mode of the vehicle to the best working mode. That is, the all-terrain control device detects that the all-terrain mode of the vehicle has not changed, but it detects that the switch of the HUT module has changed. The all-terrain control device outputs the corresponding driving mode based on the change of the switch of the HUT module. Specifically, the user can operate the switch of the HUT module to generate a driving mode switching request signal DrvModReq_HUT, which is transmitted to the all-terrain control device through the CAN bus. The all-terrain control device transmits the driving mode switching signal DrvModReq_HUT to the HCU module through the CAN bus. The HCU module controls the driving mode of the vehicle according to the driving mode switching signal DrvModReq_HUT. In this embodiment, the driving mode switching request signal DrvModReq_HUT carries the target driving mode. Through the embodiments of the present invention, a control system architecture is proposed that can take into account both manual selection of driving modes and automatic switching of driving modes, which not only improves the intelligence level of the all-terrain control system but also meets various needs of customers to the greatest extent.

[0069] In an optional embodiment, in step S104, when the all-terrain mode of the vehicle does not change, controlling the driving mode of the vehicle based on the switching request of the user includes:

[0070] Step S1041: when the user's switching request is for the pure electric mode or the energy-saving mode and the all-terrain mode of the vehicle is other modes, the driving mode of the vehicle is switched to the hybrid mode, and a prompt is given to exit the 4L mode of the four-wheel drive system; wherein the other modes are the modes in the all-terrain mode except the standard mode and the economic mode;

[0071] Step S1042: when the user's switching request is the pure electric mode or the energy-saving mode, and the all-terrain mode of the vehicle is the standard mode or the economic mode, the driving mode of the vehicle is switched according to the user's request;

[0072] Step S1043: When the user's switching request is for the hybrid mode, the driving mode of the vehicle is switched to the hybrid mode.

[0073] Specifically, in the embodiment of the present invention, when the user manually selects the driving mode through the switch on the HUT module, the switching is based on the user's subjective will, so it is possible to select a driving mode that does not match the all-terrain mode, affecting the drivability of the vehicle. In order to avoid this situation, when the user switches the driving mode of the vehicle through the switch on the HUT module, the all-terrain control device will judge the switching operation based on the correspondence between the all-terrain mode and the driving mode. Only when the switching request is correct, the driving mode is switched according to the user's switching request, that is, the driving mode of the vehicle is switched using the driving mode corresponding to the switch of the HUT module.

[0074] Specifically, when the user requests to switch the driving mode to pure electric mode or energy-saving mode through the switch on the HUT module, and the all-terrain mode of the vehicle is Sport mode, Snow mode, Mud mode, Sand mode, 4L mode, Rock mode, Mountain mode, Pothole mode or Mud_Sand mode, the all-terrain control device switches the driving mode of the vehicle to HEV mode; when the user requests to switch the driving mode to pure electric mode or energy-saving mode through the switch on the HUT module, and the all-terrain mode of the vehicle is Standard mode or ECO mode, the all-terrain control device will switch the driving mode of the vehicle according to the user's switching request. If the user's switching request is EV mode, the all-terrain control device switches the driving mode of the vehicle to EV mode; when the user requests to switch the driving mode to hybrid mode through the switch on the HUT module, since the hybrid mode is applicable to all terrain modes, the all-terrain control device switches the driving mode of the vehicle to HEV mode.

[0075] In an optional embodiment, the all-terrain control method further includes:

[0076] Step S105: When the driving mode of the vehicle has not changed, the all-terrain mode of the vehicle is switched based on a switching request of the user, and the switching request of the user is triggered by a switch of the ATS module.

[0077] Specifically, in the embodiment of the present invention, in addition to switching the all-terrain mode based on the change of the driving mode, the user can also switch the all-terrain mode through the switch on the ATS module to switch the all-terrain mode of the vehicle to the best working mode. That is, the all-terrain control device detects that the driving mode of the vehicle has not changed, but it detects that the switch of the ATS module has changed. The all-terrain control device outputs the corresponding all-terrain mode based on the change of the switch of the ATS module. Specifically, the user can operate the switch of the ATS module to generate an all-terrain mode switching request signal DrivingModReq, which is transmitted to the all-terrain control device through the CAN bus. The all-terrain control device transmits the all-terrain mode switching request signal DrivingModReq to the ATS module through the CAN bus. The ATS module controls the all-terrain mode of the vehicle according to the all-terrain mode switching request signal DrivingModReq. ​​In this embodiment, the all-terrain mode switching request signal DrivingModReq carries the target all-terrain mode.

[0078] Through the embodiments of the present invention, a control system architecture is proposed that can take into account both manual selection of all-terrain mode and automatic switching of all-terrain mode, which not only improves the intelligence of the all-terrain control system but also meets various needs of customers to the greatest extent.

[0079] In an optional embodiment, in step S105, when the driving mode of the vehicle has not changed, switching the all-terrain mode of the vehicle based on the switching request of the user includes:

[0080] Step S1051: when the user's switching request is for other modes, the all-terrain mode of the vehicle is switched according to the user's request, and a prompt is given to exit the 4L mode of the four-wheel drive system; wherein the other modes are the modes in the all-terrain mode except the standard mode and the economy mode;

[0081] Step S1052: When the user's switching request is the standard mode or the economic mode, the all-terrain mode of the vehicle is switched according to the user's request.

[0082] Specifically, in the embodiment of the present invention, when the user manually switches the all-terrain mode through the switch on the ATS module, the switching is based on the user's subjective will, so it is possible to select an all-terrain mode that does not match the drive mode, affecting the drivability of the vehicle. In order to avoid this situation, when the user switches the all-terrain mode of the vehicle through the switch on the ATS module, the all-terrain control device will judge the switching operation based on the correspondence between the drive mode and the all-terrain mode. Only when the switching request is correct, the drive mode is switched according to the user's switching request, that is, the all-terrain mode corresponding to the switch of the ATS module is used to switch the all-terrain mode of the vehicle.

[0083] Specifically, when the user requests to switch the all-terrain mode to Sport mode, Snow mode, Mud mode, Sand mode, 4L mode, Rock mode, Mountain mode, Pothole mode, or Mud_Sand mode through the switch on the ATS module, the all-terrain mode of the vehicle is switched according to the user's request, and the user is prompted to exit the 4L mode of the four-wheel drive system. When the user requests to switch the all-terrain mode to Standard mode or ECO mode through the switch on the ATS module, the all-terrain mode of the vehicle is switched according to the user's request. For example, if the user's switching request is Snow mode, the all-terrain control device switches the all-terrain mode of the vehicle to Snow mode, and prompts the user to exit the 4L mode of the four-wheel drive system.

[0084] In an optional embodiment, the hybrid vehicle is equipped with: an ESP module, an EMS module, a TCU module, a 4WD module, an EPS module, an EDL module and an IP instrument, and the all-terrain control method further includes:

[0085] Step S106, based on the correspondence between the all-terrain mode and the ESP module, EMS module, TCU module, 4WD module, EPS module, EDL module, and IP instrument, respectively control the ESP module, EMS module, TCU module, 4WD module, EPS module, EDL module, and IP instrument to operate.

[0086] Specifically, in the embodiment of the present invention, the ATS module is connected to the ESP (Electronic Stability Program, electronic stability system) module, the EMS (Engine Management System, engine management system) module, the TCU (Transmission Control Unit, transmission control unit) module, the 4WD (FourWheel Driving System, four-wheel drive system) module, the EPS (Electric Power Steering, electronic power steering system) module, the EDL (Electronic Differential Lock, electronic differential lock) module and the IP (Instrument Panel, instrument) through the CAN bus. When the all-terrain mode changes, the ESP module, the EMS module, the TCU module, the 4WD module, the EPS module, the EDL module and the IP instrument will also adopt corresponding control strategies (performed according to Table 1). For example, when the all-terrain mode is switched from the Standard mode to the Snow mode, the ESP module, the EMS module, the TCU module, the 4WD module, the EPS module, and the EDL module will also perform corresponding operations in the Snow mode.

[0087] Figure 2 A flow chart showing a control strategy of a driving mode according to an embodiment of the present invention is shown. Figure 2 , the control method of the driving mode in this embodiment is:

[0088] S201, monitoring whether the all-terrain mode of the vehicle changes, and when the all-terrain mode of the vehicle changes, executing S202; when the all-terrain mode of the vehicle does not change, executing S203;

[0089] S202, detecting whether the changed all-terrain mode is the Standard mode or the ECO mode; if so, maintaining the vehicle driving mode; if not, switching the vehicle driving mode to the HEV mode;

[0090] S203, monitoring whether the switch of the HUT module changes, when the switch of the HUT module changes, executing S204; when the switch of the HUT module does not change, maintaining the driving mode of the vehicle;

[0091] S204, detecting whether the driving mode corresponding to the switch of the HUT module is the EV mode or the SAVE mode; if so, executing S205; if not, switching the driving mode of the vehicle to the HEV mode;

[0092] S205. Detect whether the all-terrain mode of the vehicle is Sport mode, Snow mode, Mud mode, Sand mode, 4L mode, Rock mode, Mountain mode, Pothole mode or Mud_Sand mode. If so, switch the vehicle's driving mode to HEV mode and remind the user to exit 4L mode; if not, switch the vehicle's driving mode according to the driving mode corresponding to the switch of the HUT module.

[0093] Specifically, in the embodiment of the present invention, the all-terrain control device continuously monitors the all-terrain mode of the vehicle and the switch of the HUT module. (1) When the all-terrain mode of the vehicle changes but the switch of the HUT module does not change, the control of the driving mode is performed according to S202; (2) When the all-terrain mode of the vehicle does not change but the switch of the HUT module changes, the control of the driving mode is performed according to S204 and S205; (3) When both the all-terrain mode of the vehicle and the switch of the HUT module change, since the priority of the all-terrain mode is higher than the switch of the HUT module, the control of the driving mode is performed according to S202.

[0094] For example, when the all-terrain mode of the vehicle changes from Sport mode to Rock mode, but the switch of the HUT module does not change, the all-terrain control device will switch the vehicle's driving mode to HEV mode. In this embodiment, since the driving mode corresponding to the Sport mode before the change is the HEV mode, it can be understood here that the driving mode remains unchanged. However, when the all-terrain mode changes from Standard mode to Sport mode, the driving mode corresponding to the Standard mode (EV mode, SAVE mode, or HEV mode) needs to be switched to HEV mode.

[0095] For example, when the all-terrain mode of the vehicle has not changed (the current all-terrain mode is Standard mode), but the switch of the HUT module has changed, the driving mode corresponding to the switch of the HUT module has changed from HEV mode to EV mode. At this time, the all-terrain control device will switch the driving mode of the vehicle to EV mode.

[0096] Figure 3 FIG. 1 is a flow chart showing a control strategy of an all-terrain mode according to an embodiment of the present invention. Figure 3 , the control method of the all-terrain mode in this embodiment is:
