TECHNICAL FIELD

[0001] The present application relates to the field of driving assistance systems and motorcycles, in particular to a motorcycle handlebar heating control method and system, a control device and a motorcycle. BACKGROUND

[0002] When driving a motorcycle in winter, in order to avoid cold hands, the driver usually wears gloves or adds an electric heating system to the handlebar. The former reduces the flexibility of the handlebar operation and also brings inconvenience in carrying and placing the gloves. The latter mainly heats the handlebar, so the driver still feels uncomfortable when the back of the hand is exposed to the wind. To solve this problem, the present application provides a handlebar heating system and a motorcycle to solve the problem of cold hands of the driver in winter. SUMMARY

[0003] The purpose of the present application is to provide a motorcycle handlebar heating control method and system, a control device and a motorcycle to solve the technical problem of cold hands of the rider during driving.

[0004] To solve the above technical problem, the present application provides a motorcycle handlebar heating control method, comprising the following steps: determining whether the heating switch is opened; determining whether the power supply device with a water-cooled radiator is started; determining whether the ambient temperature value is less than the first threshold value and the water temperature value of the water-cooled radiator is greater than the first threshold value; when the heating switch is opened, the power supply device is started, the ambient temperature value is less than the first threshold value, and the water temperature value of the water-cooled radiator is greater than the first threshold value, the electromagnetic valve is opened, and the motorcycle handlebar heating stage is entered, realizing the water circulation between the water-cooled radiator and the heating device; otherwise, the electromagnetic valve is closed.

[0005] Through the above method, the heat of the cooling water in the existing water-cooled radiator arranged inside the motorcycle can be directly used for heating at the handlebar position, without the need to add additional heating equipment, saving costs, and at the same time, the heat dissipation of the cooling water is accelerated through the heat exchange between the cooling water and the air warmer.

[0006] Further, in the motorcycle handlebar heating stage, the following steps are further included: determining the size relationship between the actual temperature and the first target temperature value; when the actual temperature is greater than the first target temperature value, the electromagnetic valve is closed; when the actual temperature is less than the first target temperature value, the electromagnetic valve is opened.

[0007] The actual temperature can be the temperature of the handlebar or the temperature around the heating device.

[0008] Further, the first target temperature value is composed of a first temperature set value and a second temperature threshold value, when the actual temperature value is greater than the sum of the first temperature set value and the second threshold value, the electromagnetic valve is controlled to be closed; when the actual temperature value is less than the difference between the first temperature set value and the second threshold value, the electromagnetic valve is controlled to be opened.

[0009] The second temperature threshold value can prevent the heating system from frequently starting and stopping, reduce energy loss, and increase the service life of system components.

[0010] Further, in the motorcycle handlebar heating stage, the speed of the electronic water pump is controlled to be closed-loop regulated with temperature feedback, including the following steps: A first temperature difference value is obtained by the second target temperature value minus the actual temperature value; The target speed = K P1 * the first temperature difference value + K I1 * the integral of the first temperature difference value + K D1 The target speed is calculated by the differential calculation of the first temperature difference value; The speed of the electronic water pump is controlled to be equal to the target speed.

[0011] Through the above steps, the water flow of the heating system is controlled to achieve the effect of controlling the temperature of the heating device.

[0012] Further, in the motorcycle handlebar heating stage, the following steps are further included: When the value of (inlet water flow-outlet water flow) * time > third threshold value or the difference between the inlet water flow and the outlet water flow > fourth threshold value, the electromagnetic valve is controlled to be closed.

[0013] Through the above steps, it is determined whether there is a leakage problem in the water circulation of the heating system, and the valve is closed in time when the leakage problem occurs.

[0014] Further, after determining that the power supply device is started, the water cooling system control stage is entered, and the specific steps of the water cooling system control stage are as follows: The size relationship between the water temperature value of the water cooling radiator and the third target temperature value is determined; When the water temperature value of the water cooling radiator is less than the third target temperature value, the variable intake grille is closed; when the water temperature value of the water cooling radiator is greater than the third target temperature value, the opening angle of the variable intake grille is controlled to be closed-loop regulated with the radiator water temperature to maintain the radiator water temperature equal to the second target temperature value.

[0015] Further, the closed-loop regulation of the opening angle of the variable intake grille with the radiator water temperature includes the following steps: A second temperature difference value is obtained by the second target temperature value minus the actual temperature value; The target opening degree = KP2 * second temperature difference + K I2 * second temperature difference integral + K D2 * second temperature difference differential calculation target grid opening; The opening of the variable intake grid is controlled to be equal to the target grid opening.

[0016] Through the above steps, the temperature of the cooling water in the water-cooled radiator can be quickly raised when the temperature is not high, and the water temperature can be maintained.

[0017] In a second aspect, the application further provides a control device, comprising an information receiving unit, a control unit, and a calculation unit, which can realize the motorcycle handlebar heating control method to control the heating of the motorcycle handlebar position.

[0018] In a third aspect, the application further provides a motorcycle handlebar heating system, comprising a heating device, a power supply device with a water-cooled radiator, a control device, a solenoid valve, a flow detection device, a radiator water temperature detection device, an ambient temperature detection device, an electronic water pump and a heating device temperature detection device, a variable intake grid, and a motor for changing the opening of the variable intake grid. The control device is connected to the solenoid valve, the flow detection device, the radiator water temperature detection device, the ambient temperature detection device, the electronic water pump, the heating device temperature detection device, and the motor. The heating device is used to heat the motorcycle handlebar. The variable intake grid and the motor are arranged on the water-cooled radiator. The water-cooled radiator is connected to the heating device through a pipeline to realize water circulation between the water-cooled radiator and the heating device. The solenoid valve is used to open or shut off the water circulation between the water-cooled radiator and the heating device. The flow detection device is used to detect the water flow in the pipeline. The electronic water pump is used to control the water flow of the water circulation between the water-cooled radiator and the heating device.

DETAILED DESCRIPTION

[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] The core of the present application is to provide a motorcycle handlebar heating control method to solve the technical problem of cold hands of a rider during driving.

[0026] In order to make the person skilled in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0027] With reference to Figure 1 The present application provides a motorcycle handlebar heating system, comprising a heating device, a power supply device with a water-cooled radiator 1, a control device 13, a solenoid valve 6, a flow detection device 7, a radiator water temperature detection device, an ambient temperature detection device, an electronic water pump 9 and a heating device temperature detection device, a variable air intake grille 12 and a motor 11 for changing the opening degree of the variable air intake grille 12. The heating device is used for heating the handlebar of the motorcycle. The variable air intake grille 12 and the motor 11 are arranged on the water-cooled radiator 1, specifically, they are arranged at the front end of the water-cooled radiator 1. The control device 13 is connected with the solenoid valve 6, the flow detection device 7, the radiator water temperature detection device, the ambient temperature detection device, the electronic water pump 9, the heating device temperature detection device and the motor 11. The water-cooled radiator 1 is connected with the heating device through a pipeline, for realizing water circulation between the water-cooled radiator 1 and the heating device. The solenoid valve 6 is used for opening or shutting off the water circulation between the water-cooled radiator 1 and the heating device. The flow detection device 7 is used for detecting the water flow in the pipeline. The electronic water pump 9 is used for controlling the water flow of the water circulation between the water-cooled radiator 1 and the heating device.

[0028] The handlebar heating system can be applied to a motorcycle to solve the problem of cold hands of a rider during driving.

[0029] The heating device can be arranged inside the handlebar to directly act on the handlebar, so that the rider feels the heat in the palm.

[0030] More preferably, the heating device consists of a fan heater 4 and a handle air guide cover 5, with the fan heater 4 located inside the handle air guide cover 5. The fan heater 4 is connected to the water-cooled radiator 1 via a pipe. The handle air guide cover 5 is located at the front end of the handle, and has an air inlet 21 and a handle receiving opening 22 for transferring heat from the fan heater 4 to the handle. Heat can be dissipated by designing heat dissipation fins 41 on the fan heater 4, and the fan heater 4 also has a fan heater inlet 42 and a fan heater outlet 43 for connecting water pipes.

[0031] It should be noted that in this article, the direction of travel of a motorcycle when it is not in reverse gear is defined as forward.

[0032] With the above structure, the heat from the cooling water in the existing water-cooled radiator 1 inside the motorcycle can be directly used to heat the handlebars. The motorcycle can be a two-wheeled to a four-wheeled motorcycle, and the water-cooled radiator 1 can be a device for dissipating heat from power-providing equipment (such as the engine, motor 11, power battery, etc., which can provide power to the motorcycle), eliminating the need for additional heating equipment and saving costs. At the same time, the heat exchange between the cooling water and the fan heater 4 accelerates the dissipation of heat from the cooling water. The fixing position of the handlebar air guide 5 can be determined according to the overall shape of the vehicle. Optionally, the handlebar air guide 5 can be fixed to the handlebars by welding, snap-fitting, threaded connection, etc. The handlebar air guide 5 can be a one-piece design or it can be spliced ​​from several plates.

[0033] Reference Figure 2 A protective isolation piece 51 can be installed inside the handlebar air guide 5. The protective isolation piece 51 is used to separate the air heater 4 from the handlebar to prevent the rider's hands from coming into contact with the high temperature air heater 4.

[0034] The shape of the handle air guide shroud 5, the number of ducts, and the structure of the protective isolation component 51 can be designed according to the actual product structure, and are not limited here. The protective isolation component can be plate-shaped, or it can be designed as... Figure 2 The strip structure shown, installed between the handle heater 4 and the handle, optimizes the ventilation area.

[0035] In one embodiment, the air inlet 21 formed on the handle air guide shroud 5 is composed of a combination of multiple small openings, which can effectively prevent larger external objects from entering the air guide shroud through the openings and causing damage to internal components. The shape of the small openings can be designed as needed, and optionally, a combination of small openings can be used. Figure 2 The square design provided in the text.

[0036] Reference Figure 1The handlebar heating system further comprises a solenoid valve 6 arranged on the pipeline for controlling the inflow or outflow of cooling water into the hand warmer 4. The arrangement position of the control device 13 can be determined according to the overall layout of the vehicle and can be installed or integrated in the control device position of the vehicle body. The control device 13 is connected with the solenoid valve 6 to realize the automatic control of the heating system.

[0037] The handlebar heating system further comprises a flow detection device 7 connected with the control device 13 for detecting the water flow in the pipeline. The flow detection device 7 can be a flow sensor electrically connected with the control device 13 to determine whether the water circuit has a leakage problem. The flow detection device 7 can be arranged at the water inlet / outlet port 43 of the water-cooled radiator 1 or the water inlet / outlet port 42 of the hand warmer 4 or any position close to the pipeline. When the solenoid valve 6 is in the open state, if the flow is suddenly and continuously reduced, it is determined that the water circuit has a leakage problem.

[0038] In an embodiment, the handlebar heating system further comprises a heating switch 8 connected with the control device 13 to realize the start / stop control of the handlebar heating system. The rider can turn on or off the handlebar heating system through the heating switch 8 according to the ambient temperature. The heating switch 8 is preferably arranged at a position outside the motorcycle which is convenient for the rider to operate and can be arranged on the handlebar seat switch assembly 10 of the handlebar.

[0039] In an embodiment, the handlebar heating system further comprises a radiator water temperature detection device and an ambient temperature detection device, both of which are connected with the control device 13. The radiator water temperature and the ambient temperature are compared to determine whether the handlebar heating system needs to be started. Both the radiator water temperature detection device and the ambient temperature detection device can be sensors electrically connected with the control device 13. The radiator water temperature detection device can be installed inside the radiator and the installation position of the ambient temperature detection device can be determined according to the overall layout of the vehicle body.

[0040] The water-cooled radiator 1 is designed with a variable air inlet grille 12. The opening angle of the variable air inlet grille 12 is controlled by a motor 11 connected with the control device 13 for adjusting the temperature change speed. When the motorcycle is just started and the internal components are not warmed up, the grille is in a closed state to reduce the ventilation with the outside world to achieve the effect of rapid warming. After warming up, the opening angle of the variable air inlet grille 12 is controlled according to the demand to control the air inlet amount so that the water temperature is maintained within the normal working range.

[0041] The handle heating system further comprises an electronic water pump 9 and a heating device temperature detection device, the cover inside temperature detection device is used for detecting the temperature inside the handle air guide cover 5, the electronic water pump 9 and the heating device temperature detection device are electrically connected with the control device 13. The rotation speed of the electronic water pump 9 is adjusted according to the temperature target reaching condition, so as to realize the control of the water flow of the handle heating system and achieve the effect of controlling the temperature of the air heater 4. Optionally, the electronic water pump 9 is arranged at the connection between the water cooling radiator 1 and the pipeline or on the pipeline, and the heating device temperature detection device is arranged inside the handle air guide cover 5 close to the air heater 4.

[0042] It should be noted that the control device 13 is not limited to a single controller, and can be integrated into the general controller of the motorcycle, or can be a combination of multiple controllers. In one embodiment, the control device includes a power supply device controller and a heating system controller, and any one or any multiple of the above-mentioned detection devices can be connected with the power supply device controller and the heating system controller, that is, the detection device or the motor is electrically connected with the power supply device controller, and the power supply device controller is communicatively connected with the heating system controller to transmit the detection signal of the detection device to the heating system controller.

[0043] In one embodiment, the handle air heater 4 is provided as two, which are distributed at the front ends of the left and right handles of the motorcycle, and the water cooling radiator 1 and the two handle air heaters 4 are connected by three pipelines. Specifically, the water outlet 43 of the water cooling radiator 1 is connected with the water inlet 42 of the first handle air heater 4 through the first pipeline, the water outlet 43 of the first handle air heater 4 is connected with the water inlet 42 of the second handle air heater 4 through the second pipeline, and the water outlet 43 of the second handle air heater 4 is connected with the water inlet of the water cooling radiator 1 through the third pipeline.

[0044] More preferably, the pipeline is composed of an air heater water inlet pipe 2 and an air heater water outlet pipe 3, and the air heater water inlet pipe 2 and the air heater water outlet pipe 3 are all three-way pipelines. The air heater water inlet pipe 2 is connected with the two air heaters and the water cooling radiator 1, and the air heater water outlet pipe 3 is connected with the two air heaters and the water cooling radiator 1. Through the above structure, the water inlets of the left and right handle air heaters 4 are branched, and the water outlets are converged, so that the left and right handle air heaters 4 can obtain close heat dissipation, and the situation that one handle is hot and the other handle is cold is avoided.

[0045] Meanwhile, the application also provides a motorcycle handle heating control method, comprising the following steps: determining whether the heating switch 8 is opened; determining whether the power supply device with the water-cooled radiator 1 is started; determining whether the ambient temperature value is less than the first threshold value and the water temperature value of the water-cooled radiator 1 is greater than the first threshold value; when the heating switch 8 is opened, the power supply device is started, the ambient temperature value is less than the first threshold value, and the water temperature value of the water-cooled radiator 1 is greater than the first threshold value, the electromagnetic valve 6 is controlled to be opened, the motorcycle handle heating stage is entered, and the water circulation between the water-cooled radiator 1 and the heating device is realized; otherwise, the electromagnetic valve 6 is controlled to be closed. The method can be applied to the motorcycle to realize the controllable heating of the motorcycle handle.

[0046] The above determining steps can be executed in any order, the starting signal of the power device can be provided by the control device of the power device or the whole vehicle control device, or even directly linked with the motorcycle starting key.

[0047] Further, in the motorcycle handle heating stage, the following steps are further included: determining the size relationship between the actual temperature and the first target temperature value; when the actual temperature > the first target temperature value, the electromagnetic valve 6 is controlled to be closed; when the actual temperature < the first target temperature value, the electromagnetic valve 6 is controlled to be opened.

[0048] The actual temperature can be the temperature of the handle or the temperature around the heating device.

[0049] Further, the first target temperature value is composed of the first temperature setting value and the second temperature threshold value, when the actual temperature value is greater than the sum of the first temperature setting value and the second threshold value, the electromagnetic valve 6 is controlled to be closed; when the actual temperature value is less than the difference between the first temperature setting value and the second threshold value, the heating system controls the electromagnetic valve 6 to be opened. Through the setting of the second temperature threshold value, the frequent starting and closing of the heating system can be prevented, the energy loss is reduced, and the service life of the system elements is increased.

[0050] Further, in the motorcycle handle heating stage, the speed of the electronic water pump 9 is controlled as the feedback of the temperature for closed-loop regulation, comprising the following steps: a first temperature difference value is obtained through the second target temperature value - the actual temperature value; a target speed = K P1 * the first temperature difference value + K I1 * the first temperature difference value integral + K D1 the target speed is calculated through the first temperature difference value differential; the speed of the electronic water pump 9 is controlled to be equal to the target speed.

[0051] Through the above steps, the water flow of the heating system is controlled to achieve the effect of controlling the temperature of the heating device. Suitable PID control parameters can be obtained through pre-experiments.

[0052] Further, in the motorcycle handle heating stage, the following steps are further included: When the value of (inlet water flow-outlet water flow) * time > third threshold value or the difference between inlet water flow and outlet water flow > fourth threshold value, the electromagnetic valve 6 is controlled to be closed.

[0053] Through the above steps, it is determined whether the water circulation of the heating system has a leakage problem, and the valve is closed in time when the leakage problem occurs. Specifically, when the difference between inlet water flow and outlet water flow > fourth threshold value, it is concluded that the outlet water flow of the heating system is less than the inlet water flow, and the heating system may have a water leakage problem. When the value of (inlet water flow-outlet water flow) * time > third threshold value, the total amount of leakage can be calculated by (inlet water flow-outlet water flow) * time. When the total amount of leakage is too large, the electromagnetic valve 6 is closed.

[0054] Further, after determining that the power supply device is started, the water cooling system control stage is entered. The specific steps of the water cooling system control stage are as follows: Determine the size relationship between the water temperature value of the water cooling radiator 1 and the third target temperature value. When the water temperature value of the water cooling radiator 1 is less than the third target temperature value, the variable intake grille 12 is closed. When the water temperature value of the water cooling radiator 1 is greater than the third target temperature value, the opening angle of the variable intake grille 12 is controlled to be adjusted closed-loop with the radiator water temperature to maintain the radiator water temperature equal to the second target temperature value.

[0055] The above third target temperature value can be set as a fixed value or the same as the first target temperature value. The third target temperature value is preferably less than the second target temperature value.

[0056] Further, the control of the opening angle of the variable intake grille 12 closed-loop with the radiator water temperature includes the following steps: Obtain a second temperature difference value by the second target temperature value-actual temperature value; Obtain a target opening degree = K P2 * second temperature difference value + K I2 * second temperature difference value integral + K D2 * second temperature difference value differential calculation to obtain a target grille opening degree; The opening degree of the variable intake grille 12 is controlled to be equal to the target grille opening degree.

[0057] It should be noted that, in one embodiment protected by this invention, the second temperature difference and the first temperature difference can be the same. When the water cooling system control is enabled, the calculation of the second target temperature value minus the actual temperature value can be performed only once, and this result can be applied to the subsequent closed-loop regulation of the electronic water pump 9 based on temperature feedback. The aforementioned K... P1 With K P2 The value of K can be the same or different. I2 With K I2 K D2 With K D2 The same applies to the value.

[0058] Through the above steps, the variable air intake grille 12 can be closed when the cooling water temperature in the water-cooled radiator 1 is not high, thereby quickly increasing the internal temperature of the water-cooled radiator 1. When the internal temperature of the water-cooled radiator 1 reaches a better state, the water temperature can also be maintained by adjusting the opening angle of the variable air intake grille 12. The third target temperature value can be the optimal water temperature obtained through experimentation.

[0059] It should be noted that the aforementioned first and second thresholds can be specific values ​​or ranges. For example, when the first temperature setting is 35 degrees Celsius and the second threshold is 5 degrees Celsius, if the actual temperature is greater than 40 degrees Celsius, the solenoid valve 6 will be closed; if the actual temperature is less than 30 degrees Celsius, the solenoid valve 6 will be opened. When the first temperature setting is 30 degrees Celsius and the second threshold is 5-10 degrees Celsius, it can be set so that if the actual temperature is greater than 40 degrees Celsius, the solenoid valve 6 will be closed; if the actual temperature is less than 25 degrees Celsius, the solenoid valve 6 will be opened. Alternatively, it can be set so that if the actual temperature is greater than 45 degrees Celsius, the solenoid valve 6 will be closed; if the actual temperature is less than 30 degrees Celsius, the solenoid valve 6 will be opened. Furthermore, all the aforementioned target values, setting values, and thresholds can be freely set by the manufacturer within the control device according to requirements, or the rider can directly participate in setting specific values ​​through a human-machine interface system. In all the embodiments described above that include an electronic water pump 9, the electronic water pump 9 can be turned off while the solenoid valve 6 is closed. After the solenoid valve 6 is opened, the electronic water pump 9 will resume operation, thereby saving power.

[0060] On the other hand, the present invention also provides a control device, including an information receiving unit, a control unit, and a computing unit, which can realize the above-mentioned motorcycle handlebar heating control method.

[0061] The information receiving unit is used to receive the detection signals transmitted by the detection devices and the setting information of the manufacturer or the rider, the calculation unit is used to calculate the above mathematical formula and obtain the corresponding value, and the control unit is used to control the closing and operation of the electromagnetic valve 6, the electronic water pump 9, the motor 11 and other equipment. Further, the control device also has a storage function, which can store the setting information of the manufacturer or the rider, the mathematical formula and the related value that needs to be called, and the heating of the handlebar can be realized by configuring the control device.

[0062] Furthermore, the application also provides a motorcycle provided with the above control device, which can realize the heating of the handlebar, and the motorcycle can solve the problem of cold hands of the rider during driving.

[0063] Reference Figures 6-7 In an embodiment, the motorcycle is a fuel type motorcycle, and the water-cooled radiator 1 is used for engine heat dissipation of the motorcycle, and the specific control mode is as follows: When the electromagnetic valve 6 is opened, the cooling water in the engine water-cooled radiator 1 enters the handlebar air heater 4 through the air heater inlet pipe 2, and then returns to the water-cooled radiator 1 through the air heater outlet pipe 3. When the cooling water passes through the handlebar air heater 4, the airflow during vehicle driving enters the handlebar air guide cover 5 through the air inlet opening 21 of the handlebar air guide cover 5 and flows through the heat dissipation fins 41 of the handlebar air heater 4, so as to take the heat in the cooling water to the air guide cover handlebar containing opening 22, thereby realizing the air heating and heating of the hands of the driver. The handlebar air heater inlet pipe 2 and the handlebar air heater outlet pipe 3 are provided with a three-way pipe near the center of the motorcycle handlebar cross pipe, which can divide the cooling water entering the left and right handlebar air heaters 4, so that the left and right handlebar air heaters 4 can obtain close heat dissipation amount.

[0064] After the motorcycle engine is started, the control device 13 can determine whether to start the handlebar heating system according to the detection signals of the radiator water temperature sensor and the environment temperature sensor. Specifically, the radiator water temperature sensor and the environment temperature sensor are connected with the control device 13 through the engine control device, and the detection signals are transmitted to the control device 13 through the engine control device.

[0065] When the following conditions are met simultaneously: The environment temperature is less than the first threshold value; The water temperature value of the radiator is greater than the first threshold value; It is determined that the handlebar heating system needs to be started, otherwise it is determined that the heating system does not need to be started.

[0066] When it is determined that the handle heating system needs to be started, the control device 13 controls the water inlet pipe 2 electromagnetic valve 6 and the water outlet pipe 3 electromagnetic valve 6 to open, and the cooling water in the radiator enters the handle air heater 4 through the water inlet pipe 2 of the air heater, and then returns to the water-cooled radiator 1 through the water outlet pipe 3 of the air heater. When the cooling water passes through the handle air heater 4, the airflow during vehicle driving enters the handle air deflector 5 through the air inlet opening 21 of the handle air deflector 5 and flows through the heat dissipation fins 41 of the handle air heater 4, bringing the heat in the cooling water to the handle containing opening 22 of the air deflector, realizing the air heating heating of the driver's hands. The flow sensor arranged at the inlet and outlet of the radiator 43 judges whether the water circuit of the handle heating system leaks by calculating the flow difference of the inlet and outlet 43, and the control device 13 can close the valve when leakage occurs.

[0067] The difference between the inlet flow and the outlet flow is greater than the fourth threshold value, which can be determined that there is leakage at this time, or the total amount of leakage can be obtained by using (inlet flow-outlet flow)*time. When the total amount of leakage is too large, the valve is closed, and the electronic water pump 9 is closed.

[0068] The rider can turn on or off the electromagnetic valve 6 through the heating switch 8 according to the riding temperature, and more intelligently, the driver can set the heating system temperature target value and threshold value through the vehicle machine interaction system. When the heating switch 8 is turned off, the control device 13 does not open the electromagnetic valve 6 under various working conditions. When the heating switch 8 is turned on, the control device 13 opens and closes the electromagnetic valve 6 according to the actual temperature and the size of the first target temperature value.

[0069] The temperature signal (actual temperature) of the in-cage temperature detection device arranged in the handle air deflector 5 is transmitted to the control device 13, and the control device 13 adjusts the speed of the electronic water pump 9 according to the set temperature target to achieve the effect of controlling the air heating temperature. The speed of the electronic water pump 9 is closed-loop regulated with temperature as feedback.
