[0103] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0104] The control method, control device, electronic device and storage medium of the electric power-assisted vehicle according to the embodiments of the present invention are described below with reference to the accompanying drawings.

[0105] Before introducing the control method of the electric power-assisted vehicle of the present invention, the control system of the electric power-assisted vehicle of the embodiment of the present invention is first introduced.

[0106] Figure 1 4 is a block diagram of a control system of an electric power-assisted bicycle according to an embodiment of the present invention.

[0107] like Figure 1As shown, the control system of the electric power-assisted vehicle according to the embodiment of the present invention includes: a power determination module, a vehicle controller, a power output module, a human-computer interaction interface and a motor. Among them, the power determination module integrates a variety of sensors to fully perceive the rider's intentions and external environmental conditions, including: torque sensor, which is used to detect the rider's pedaling force on the pedal in real time. For example, by measuring the torsional torque of the pedal shaft or related components, the torque sensor can accurately convert the rider's pedaling force into an electrical signal and transmit it to the vehicle controller as an important reference for power output; cadence sensor, which is installed on the pedal or related transmission components to monitor the rider's pedaling frequency (i.e., the number of pedal rotations per minute). The cadence data combined with the torque information can more comprehensively reflect the rider's power needs and help the vehicle controller to more accurately adjust the motor assistance level; slope sensor, which is installed at the bottom of the vehicle or near the front wheel to detect the slope information of the current riding road in real time. The slope data is crucial to the control system because it directly affects the driving force required for the vehicle to travel. Through the slope sensor, the control system can automatically adjust the output power of the motor to overcome the resistance when going uphill or provide appropriate braking assistance when going downhill; brake module, which not only includes a physical brake device, but also integrates a brake sensor to detect the brake Whether the operation is performed, once the brake signal is detected, the brake module will immediately send a command to the vehicle controller to quickly cut off the power of the motor and possibly start the energy recovery mechanism (such as the brake energy recovery system), while triggering safety prompt functions such as brake lights to ensure riding safety; the vehicle controller, as the "brain" of the control system, is responsible for receiving various sensor data from the power determination module, conducting comprehensive analysis and processing, and based on the preset algorithms and logic, the vehicle controller will calculate the best motor assist strategy and send control commands to the power output module. In addition, the vehicle controller is also responsible for monitoring the battery status, system safety and fault Fault diagnosis and other functions; power output module, the power output module is mainly composed of a motor and its drive circuit, which is responsible for converting electrical energy into mechanical energy to provide the electric assisted vehicle with forward power. According to the instructions of the vehicle controller, the power output module will adjust the speed and torque of the motor to match the needs of the rider and road conditions; human-computer interaction interface, providing an interactive platform between the rider and the control system, including display screens, buttons or touch panels, etc. Riders can view the vehicle status (such as battery level, speed, mileage, etc.), adjust the power mode (such as economic mode, sports mode, etc.), and even make personalized settings through the human-computer interaction interface.

[0108] Figure 2 It is a schematic structural diagram of a control system of an electric power-assisted bicycle according to an embodiment of the present invention.

[0109] like Figure 2As shown, the control system of the electric power-assisted vehicle in the embodiment of the present invention includes: a hydrogen storage bottle, a hydrogen inlet valve, a fuel cell, a tail exhaust valve, a pressure sensor arranged at the outlet of the hydrogen storage bottle, a vehicle controller ECU, a DC / DC converter, a lithium battery, a battery management system BMS and a motor M.

[0110] Among them, the hydrogen storage bottle is used as a storage device for hydrogen, and its outlet is connected to the hydrogen inlet valve through a pipeline. The hydrogen inlet valve controls the flow of hydrogen from the hydrogen storage bottle to the fuel cell, and is then connected to the hydrogen inlet of the fuel cell through a pipeline. The fuel cell generates electricity and water through an electrochemical reaction between hydrogen and oxygen in the air. The generated electricity is transmitted to the DC / DC converter and the motor M through the power line. At the same time, the generated tail gas (mainly unreacted hydrogen and a small amount of water vapor) is discharged to the tail exhaust valve through the pipeline. The DC / DC converter converts the direct current output of the fuel cell into a voltage suitable for the lithium battery or other electrical equipment, and is connected to the lithium battery through the power line to realize energy storage or supply to other equipment. As an auxiliary power source, the lithium battery is connected to the DC / DC converter through the power line, and is also connected to the battery management system BMS to monitor the battery status in real time and manage its charging and discharging process. The battery management system BMS is responsible for monitoring the voltage, current, temperature and other parameters of the lithium battery to ensure that the battery works in a safe and efficient state, and is connected to the vehicle controller ECU through the control line to realize the transmission of information and the execution of instructions. The vehicle controller ECU is the core of the entire control system. It is connected to various components in the system (such as hydrogen inlet valve, fuel cell, DC / DC converter, battery management system BMS, etc.) through control lines, receives sensor signals (such as pressure sensor, temperature sensor, etc.), and sends control instructions to various components according to preset algorithms and logical judgments to achieve normal operation and energy management of the electric power-assisted vehicle. The motor M, as the power output device of the electric power-assisted vehicle, receives the electrical energy provided by the fuel cell and lithium battery through the power line, and converts it into mechanical energy to drive the electric power-assisted vehicle.

[0111] Working principle of the control system: When the electric assisted vehicle starts, the vehicle controller ECU sends control instructions to the hydrogen inlet valve, DC / DC converter, battery management system BMS and other components through the control line according to the received sensor signals (such as the pressure sensor monitoring the pressure value at the outlet of the hydrogen storage bottle, the temperature sensor monitoring the temperature of the fuel cell, etc.) and the user's operation instructions (such as acceleration, deceleration, braking, etc.). The hydrogen inlet valve controls the flow of hydrogen according to the instructions so that an appropriate amount of hydrogen enters the fuel cell. The fuel cell generates electricity and water through electrochemical reactions. After the electricity is converted by the DC / DC converter, part of it is directly supplied to the motor M, and the other part is stored in the lithium battery through the power line. At the same time, the battery management system BMS is responsible for monitoring the status of the lithium battery to ensure that it works within a safe and efficient range. When the electric assisted vehicle needs to slow down or stop, the motor M can be used as a generator to convert mechanical energy into electrical energy and store it in the lithium battery through the DC / DC converter to achieve energy recovery. The tail exhaust valve is responsible for safely discharging the exhaust gas generated by the fuel cell. Throughout the process, the vehicle controller ECU is responsible for coordinating the work of various components to ensure the normal operation of the electric assisted vehicle.

If the power-assist command is not actively issued through the human-computer interaction interface, the road surface slope of the current road on which the electric power-assisted vehicle is located is collected through the slope sensor and the user's pedaling frequency is collected through the pedaling frequency sensor; if the power-assist command is actively issued through the human-computer interaction interface, it is determined that the user is in a tired state and requires greater power. At this time, the output power of the electric power-assisted vehicle needs to be increased, such as controlling the power output module to output at maximum power.

[0127] If the actual pressure value is within the second set pressure range, the output power value is determined to be the rated power value of the fuel cell multiplied by a second proportion (such as 50%); wherein the upper limit value of the second set pressure range is less than the lower limit value of the first set pressure range;

[0133] Among them, the first proportion is greater than the second proportion.

[0134] That is to say, when it is determined that the electric power-assisted vehicle is in a climbing state or the user needs a higher speed, the maximum output power P1 of the fuel cell is further inferred based on the remaining power state of the lithium battery and the actual pressure value at the outlet of the hydrogen storage bottle. P1 is mainly divided into 100% PE, 80% PE, and 50% PE in the preferred embodiment of the present invention.

[0145] That is to say, when it is determined that the electric power-assisted vehicle is on a flat area or the user's pedaling frequency is low and a high speed is not required, the output power P2 of the fuel cell is further inferred based on the remaining power state of the lithium battery and the actual pressure value at the outlet of the hydrogen storage bottle. P2 is mainly divided into 50% PE, 30% PE, and 20% PE in the preferred embodiment of the present invention.

[0146] In the embodiment of the present invention, the user can send a shutdown command through the human-computer interaction interface, and the whole vehicle no longer provides power assistance when the user is riding.

[0147] Therefore, the control method of the electric power-assisted vehicle in the embodiment of the present invention actively and passively judges the power demanded by the user by judging the road slope and pedaling frequency of the road on which the electric power-assisted vehicle is located, and comprehensively infers the fuel cell output power P based on the remaining power state of the lithium battery and the actual pressure value at the outlet of the hydrogen storage bottle, thereby placing the fuel cell in the optimal operating condition, and improving the reliability of the fuel cell stack while extending the endurance of the entire vehicle.

[0148] like Figure 4 As shown, the electric power-assisted vehicle includes a heating network and a heating gasket, the heating network is used to heat the fuel cell, and the heating gasket is used to heat the hydrogen storage bottle. The above method also includes: obtaining the current ambient temperature of the electric power-assisted vehicle, and when the ambient temperature is lower than the set temperature threshold, controlling the heating network and / or the heating gasket to work until the output power value of the fuel cell reaches the rated power value of the fuel cell multiplied by the second proportion (50%), and then controlling the heating network and / or the heating gasket to stop heating.

[0149] As an example, the fuel cell and the hydrogen storage bottle can be placed in the same module, and a heating net and a heating pad are placed in the module for low-temperature cold start of the fuel cell and low-temperature deflation of the hydrogen storage bottle. First, before the fuel cell is started, the vehicle controller determines whether the heating module needs to be turned on based on the ambient temperature detected by the ambient temperature sensor. If the ambient temperature is lower than the set temperature threshold K1, the heating module is turned on so that the fuel cell can start normally at low temperature and the hydrogen storage bottle can supply gas stably at low temperature. As the power of the fuel cell increases, the power of the heating module gradually decreases, and the heating is stopped when the output power of the fuel cell reaches more than 50% PE. Because the fuel cell is adjacent to the hydrogen storage bottle, the fuel cell exhaust gas heats the hydrogen storage bottle at this time so that the hydrogen storage bottle can be deflated stably. Therefore, the present invention can greatly improve the low-temperature starting ability of the air-cooled fuel cell and the low-temperature deflation stability of the hydrogen storage bottle by adding a heating module, and the whole vehicle has active and passive power-assist modes, which greatly improves the riding experience of the user when riding.
