The shape, number and proportion of each component when actually implemented can be arbitrarily changed, and the layout form of the components can also be more complex.

[0029] The embodiments of the present application provide a care mode control method, which can be applied to a vehicle terminal and can also be software running in the vehicle terminal. For example, please refer to Figure 1 An implementation environment diagram of a care mode control method provided in the present application is shown, and the care mode control method in the present application can be applied to the scenario of care mode control. For example, as shown in Figure 1 The execution subject of the method provided in the embodiments of the present application can be a target vehicle, and the target vehicle 100 responds to user operation or executes the care mode control method provided in the embodiments to communicate with a cloud server 200 through a remote communication terminal (i.e. Telematics Box, hereinafter referred to as Tbox) provided in the target vehicle. The target vehicle includes but is not limited to a pure electric vehicle, a hybrid electric vehicle, a fuel cell electric vehicle, a gaseous fuel vehicle, a biofuel vehicle, for example, also includes a super capacitor vehicle, a flywheel energy storage vehicle, etc., and even a flying vehicle or an aircraft, etc.

[0030] In some embodiments, the cloud server 200 isFigure 1 The provided cloud services, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, and big data and artificial intelligence platform, etc. basic cloud computing services; the software can be an application program generated by a firmware program upgrade, etc., but not limited to the above forms.

[0031] The application will be described in detail below through specific embodiments. Please refer to Figure 2 as shown, Figure 2 The flow chart of the care mode control method provided by the embodiment of the application includes the following steps:

[0032] Step S210, obtaining a mode trigger instruction of the vehicle, the mode trigger instruction is generated by any one of the following modes: face recognition, voice recognition or key pressing;

[0033] Among them, the trigger instruction starts the "(old people) care mode" through the touch screen, physical button, face recognition or voice command in the vehicle, for example, the face recognition of the user face image is carried out by using the camera in the vehicle, the identity information is determined, and it is detected whether there is an old user in the vehicle through the identity information, or the above-mentioned way is adopted, the old user is first recognized by the camera, and then it is determined whether the old user is seated in the vehicle through the pressure sensor on the seat, so as to further judge whether the old user is seated or driven in the vehicle. For example, when entering the care mode, the left upper corner of the center screen of the cockpit system is clearly marked, and the icon can be directly clicked to exit or continue to use.

[0034] For example, the user's sentence is recognized by the intelligent voice recognition system, and when it is recognized that the user's sentence contains the opening care mode instruction, the "care mode" is directly opened by voice trigger.

[0035] Step S220, in response to the mode trigger instruction, controlling the vehicle to enter the care mode to adjust the vehicle configuration, wherein the care mode at least includes driving strategy.

[0036] Specifically, once the trigger instruction is received, the vehicle enters the care mode immediately, which helps to improve the user experience, reduce the waiting time, and make the vehicle more intelligent and convenient through the rapid response mechanism; at the same time, in addition to the driving strategy, the care mode can also provide customized care service according to the specific needs or situation of the user, so as to not only improve the user's satisfaction, but also provide intelligent and humanized design of the vehicle system.

[0037] In some embodiments of the present application, please refer to Figure 3 , the adjustment mode of the driving strategy includes:

[0038] Step S310, obtaining an action signal of a pedal in the vehicle, a load and a wheel diameter, the pedal being an accelerator pedal or a brake pedal;

[0039] Specifically, the action signal of the accelerator pedal or the brake pedal in the vehicle is obtained by a sensor, and the load and the wheel diameter information of the vehicle are obtained, i.e., the load and the wheel diameter information of each vehicle are known.

[0040] Step S320, determining a torque change rate according to a pedal deformation variable generating the action signal, wherein the pedal deformation variable corresponds to a pedal depth and the torque change rate are in a mapping relationship;

[0041] Specifically, the torque change rate is determined according to the pedal deformation variable (i.e., the pedal depth), and there is a mapping relationship between the pedal deformation variable and the torque change rate, i.e., different pedal depths will result in different torque change rates.

[0042] Step S330, determining an acceleration of the vehicle according to an integral of the torque change rate within start and stop times, the load and the wheel diameter;

[0043] Specifically, the acceleration of the vehicle is calculated according to the integral of the torque change rate within the start and stop times (i.e., the total amount of torque change) and in combination with the load and the wheel diameter information of the vehicle, for example, the expression for determining the acceleration of the vehicle is as follows:

[0044]

[0045] In the formula, a is the acceleration of the vehicle, K is the torque change rate of the vehicle, M is the load of the vehicle, R is the wheel diameter of the vehicle, t1 and t2 are respectively the start time and the stop time of stepping on the accelerator pedal or the brake pedal.

[0046] In the above manner, not only the dynamics and kinematics of the vehicle are considered, but also the relationship among the acceleration a, the speed V and the torque change rate K of the vehicle is determined, which is described in detail as follows:

[0047]

[0048] Step S340, if the acceleration of the vehicle tends to zero and the time curve is continuous, and the torque change rate is switched between acceleration, deceleration and constant speed, the torque change rate is adjusted by using a preset smoothing strategy, so that the speed of the vehicle is in a flexible acceleration and deceleration control interval for smooth control.

[0049] Specifically, it is checked whether the acceleration of the vehicle tends to zero and the acceleration is continuous in time. If these conditions are met, and the rate of change of torque is switched between acceleration, deceleration and constant speed, a preset smoothing strategy is adopted to adjust the rate of change of torque. In this way, not only can the vehicle be smoothly transitioned during acceleration and deceleration, but also excessive impact and vibration can be avoided, thereby improving the comfort and safety of the ride.

[0050] It should be noted that the smoothing strategy can be implemented based on PID control, fuzzy control, neural network control, etc. Control algorithm, or / and, the running state of the vehicle and the external environment to develop a suitable control strategy to ensure the smooth output of torque.

[0051] In the above manner, the rate of change of torque is accurately controlled to achieve smooth acceleration and deceleration of the vehicle, taking into account various factors of the vehicle, including pedal action, load and wheel diameter, to ensure stable and smooth vehicle control under various driving conditions, thereby improving the safety and comfort of driving.

[0052] Optionally, in an embodiment of the present application, the adjustment mode of the driving strategy further comprises:

[0053] If a zero-crossing change in torque is detected, and the start and end time corresponding to the pedal is within a preset period, the rate of change of torque is reduced within the preset period to reduce the zero-crossing impact, and a smooth torque is output.

[0054] First, zero-crossing change refers to the process of torque changing from positive to negative or from negative to positive. Such sudden changes can cause the power system of the vehicle to produce impact, affecting the stability of driving and the comfort of passengers. Therefore, it is necessary to detect and identify such zero-crossing changes.

[0055] Secondly, when a zero-crossing change is detected, it is first checked whether the change occurs within the start and end time corresponding to the pedal. If the start and end time is within a preset period, in order to ensure that only those zero-crossing changes that occur within a short period of time and may cause a larger impact are responded to.

[0056] Once the above conditions are met, the rate of change of torque is reduced, which is achieved by adjusting the parameters or algorithms of the torque control system, to reduce the rate and amplitude of torque change; in this way, by reducing the rate of change of torque, a smooth transition to zero can be achieved, avoiding excessive impact.

[0057] Finally, by reducing the rate of change of torque to reduce the zero-crossing impact, a smooth torque is output, which helps to improve the driving performance of the vehicle and the riding experience of the passengers.

[0058] Optionally, in an embodiment of the present application, the care mode further includes at least one of a seat adjustment strategy, an air conditioner adjustment strategy, a cabin adjustment strategy, and a safety adjustment strategy.

[0059] Optionally, in an embodiment of the present application, the adjustment mode of the seat adjustment strategy includes:

[0060] Obtaining the temperature in the vehicle and the identity information of the current driver, the identity information including the height and leg length of the user; adjusting the front and rear position, height, and inclination of the seat according to the height and leg length of the driver; if the temperature in the vehicle is higher than a first preset temperature, turning on the seat ventilation, and if the temperature in the vehicle is lower than a second preset temperature, turning on the seat heating.

[0061] Specifically, by determining the identity information, the height, angle, and support of the seat are automatically adjusted to adapt to the physical needs of the elderly, reducing the fatigue of long-time driving.

[0062] Among them, the seat options of heating and massage are provided to relieve the joint discomfort or muscle pain that the elderly may face, and the specific adjustment control is as follows:

[0063] For example, seat front and rear adjustment: the front and rear position of the seat is adjusted by recognizing the height and leg length of the old people to ensure that the driver's feet can be comfortably placed on the accelerator and brake, and the knees will not be excessively bent.

[0064] For example, seat height adjustment: the height of the seat is adjusted by recognizing the height of the old people to ensure that the driver's eyes maintain an appropriate distance and angle from the front of the car, the dashboard, and the road, thereby reducing the pressure on the neck and back. For example, seat inclination adjustment: the inclination of the seat is adjusted by recognizing the height of the old people to help the driver find the most suitable support angle for the back and neck, and the seat provides sufficient lumbar support to reduce fatigue during long-distance driving. For example, seat heating and ventilation: the ventilation and heating functions of the seat are automatically started according to the temperature and humidity in the vehicle to provide better comfort in hot weather and cold weather.

[0065] Through the above seat adjustment strategy, personalized seat comfort experience can be provided according to the body type of different drivers and the change of the temperature in the vehicle, so that the comfort of driving is improved.

[0066] Optionally, in an embodiment of the present application, the adjustment mode of the air conditioner adjustment strategy includes:

[0067] When the air conditioner in the vehicle is detected to be turned on, the target temperature in the vehicle is controlled to be in a preset temperature range, and meanwhile, the air outlet direction of the air conditioner is adjusted to enter directional ventilation to avoid directly blowing to the user; if the air quality of the fresh air volume of the directional ventilation is detected to be lower than a preset air quality, the air inlet volume is reduced; if the air quality of the fresh air volume of the directional ventilation is detected to be higher than the preset air quality, the air inlet volume is increased.

[0068] Specifically, the air conditioner temperature and air volume are automatically adjusted according to the temperature in the vehicle and the preference of the elderly, to ensure comfort and not too cold or hot.

[0069] It should be noted that the air conditioner adjustment provides a directional ventilation function to avoid directly blowing to the elderly, to reduce discomfort. For temperature, the comfortable temperature of the elderly is usually between 22℃ and 26℃, and the humidity is at a relative humidity of 40% to 60%, and at the same time, the air exchange rate in the vehicle is accelerated to achieve better air oxygen content. Specifically as follows:

[0070] For example, the fresh air volume is controlled: the air inlet fan speed is adjusted through the PM2.5 sensor in the vehicle, when the PM2.5 is lower than the threshold, the air inlet volume is reduced; when the P2,5 is greater than the threshold, the air inlet volume is increased.

[0071] For another example, the air supply mode is adjusted: when the air inlet temperature and humidity are high and low, the air outlet is controlled to avoid directly blowing to the face.

[0072] Through the above air conditioner adjustment strategy, not only the comfort of the passenger is considered, but also the quality of the air in the vehicle is considered; and through accurate control of various parameters of the air conditioner system, the best riding experience can be provided for the passenger in different environments.

[0073] Optionally, in an embodiment of the present application, the adjustment mode of the cabin adjustment strategy comprises:

[0074] Switching the interactive interface of the cabin system, increasing the font, icon and contrast of the interactive interface, and starting the voice interaction function;

[0075] If a voice instruction is received, the voice instruction is responded to and voice feedback is performed; if a touch instruction of the cabin system is received, the touch instruction is voice broadcasted.

[0076] Specifically, the user interface of the infotainment (cabin) system is simplified or switched, large font, high contrast and clear icons are provided to facilitate the elderly to read and operate. For example: voice prompts after selecting each function are increased, commonly used function icons such as window switch, temperature adjustment, seat massage heating, etc. are increased and brightened, and at the same time, a voice control function is integrated, the elderly can operate the vehicle-mounted system through voice commands without complex manual input.

[0077] Through the above cabin adjustment mode, different user needs and scenarios can be more intelligently adapted, and the comfort and safety of driving and riding can be improved.

[0078] In an embodiment of the present application, the adjustment mode of the safety adjustment strategy includes:

[0079] The automatic emergency braking, lane keeping assistance, fatigue driving monitoring and pedestrian recognition are adjusted to an open state, and the physical information of the driver during vehicle driving is collected; if the physical information is monitored to be in an abnormal state (for example, rapid heart rate, high blood pressure or abnormal breathing, etc.), the health status of the driver is determined through voice interaction, for example, the driver is communicated through voice interaction, and whether he feels unwell is inquired, and the specific health status is tried to be determined; if it is determined that the health status of the driver is abnormal, the intelligent driving assistance function is started to take over the vehicle, for example, the intelligent driving assistance function is immediately started, the control right of the vehicle is taken over, the driver is sent to the corresponding hospital according to the preset first-aid strategy, and the emergency is sent to the emergency contact person and the hospital for rescue service.

[0080] For example, according to the preset first-aid strategy, the vehicle is safely driven to the nearest hospital or emergency center, such as preferentially selecting a safe and fast route, and avoiding traffic congestion or dangerous sections as much as possible. During the process of sending the driver to the hospital, the emergency is automatically sent to the emergency contact person (such as family members, friends, etc.) of the driver, informing them of the health status and current location of the driver; at the same time, real-time communication is carried out with the hospital or emergency center, and the detailed information and estimated arrival time of the driver are provided, so that the hospital can make rescue preparations in advance.

[0081] Specifically, the active safety systems of the vehicle are strengthened, such as automatic emergency braking, lane keeping assistance, fatigue driving monitoring and pedestrian recognition, etc., to reduce the potential collision risk; at the same time, a seat belt pre-tightening function is provided to better protect the safety of elderly passengers in emergency situations. For example, emergency response and contact: an emergency call button is provided in the vehicle, so that the elderly can quickly contact rescue services or family members when needed. For example, integrated vehicle health monitoring function (such as heart rate monitoring), automatically contact emergency rescue in abnormal situations. For example, health reminders and customization: provide regular activity and rest reminders to avoid physical discomfort caused by long-term sitting in the same position. Allow the elderly to customize the settings of the care mode according to personal preferences and health status, such as seat position, temperature preference, etc.

[0082] In the above manner, the vehicle can quickly respond when the driver's health is abnormal, ensure the safety of the driver and timely treatment, and prevent various emergencies of the elderly.

[0083] In the embodiment, the adjustment to the care mode through the mode recognition makes the care mode have the comprehensive application of the control methods of the "seat comfort adjustment", the "air quality adjustment", the "cabin system adjustment", the "driving strategy adjustment" and the "safety function adjustment", so as to provide the old passenger with a more comfortable, safe and convenient riding experience.
