A New Energy Sweeping Control Method
Patent Number: CN116540746B
Abstract: This invention discloses a new energy sweeping control method, which includes: setting the working area of a new energy sweeping vehicle and establishing a coordinate system for the vehicle within the working area; obtaining the power consumption (d) and travel distance (l2) of each historical sweeping task; issuing sweeping tasks to the new energy sweeping vehicle, determining the movement trajectory based on the task, and calculating whether the remaining power is sufficient to execute the task. If it is sufficient, the task is directly executed; otherwise, a charging task is performed first, followed by the sweeping task. This solution improves the accuracy of trajectory planning by utilizing historical sweeping tasks, enabling the direct retrieval of trajectories from the task database without the need for complex and long-distance trajectory and obstacle avoidance algorithms, while still achieving high-precision sweeping.
An Electric Vehicle Chassis System and Control Method
Patent Number: CN115593273B
Abstract: This invention discloses an electric vehicle chassis system and control method. The chassis system includes a suspension safety monitoring system, steering control system, braking system, safety system, battery system, driving system, and control system. The battery system comprises a charging module, discharging module, and battery safety and lifespan monitoring module. The battery safety and lifespan monitoring module measures the battery capacity during vehicle entry, exit, and charging, and evaluates the safety and lifespan of the battery. The suspension safety monitoring system includes several deformation sensors installed at welding and support points on the load-bearing suspension to monitor its deformation. The control method for the battery safety and lifespan monitoring module includes steps S1-S11. This invention integrates the battery safety and lifespan monitoring module into the electric vehicle chassis system to comprehensively evaluate the battery lifespan and status.
A Fuel Cell System Power Control Method and System Based on State Control
Patent Number: CN115991099B
Abstract: This invention discloses a fuel cell system power control method and system based on state control. The method includes: S1, vehicle power-on self-check; S2, performing FCU self-check if no abnormalities are found during the vehicle self-check; if a fault is detected, proceed to step S3; if not, proceed to step S4; S3, shutting down the fuel cell and sending a fault message to the vehicle control unit (VCU); S4, starting the fuel cell, determining the current vehicle state based on collected vehicle operating parameters, and adjusting the target power of the fuel cell accordingly. This invention uses a state-based approach to determine the vehicle’s power demand, integrating relevant battery, motor, and electronic control component statuses to ensure that the fuel cell operates in the optimal working range with minimal fuel consumption rate, thereby achieving longer range and greater reliability, and effectively improving the vehicle’s economy and the fuel cell’s lifespan.
A Locomotive Backup Emergency Braking System
Patent Number: CN116080613B
Abstract: This application provides a locomotive backup emergency braking system. The system is connected to three pins of the vehicle control unit (VCU). The first end of the first exhaust relay in the system is connected to the first pin of the VCU, the second end is connected to the power supply voltage, and the third end is connected to the third end of the second exhaust relay, and the relay switch of the first exhaust relay connects its second end and third end. The first end of the second exhaust relay in the system is connected to the second pin of the VCU, the second end is connected to the exhaust port of the parking memory valve, and the fourth end is connected to the power supply voltage, and the relay switch of the second exhaust relay connects its second end and third end. When the VCU fails and no signals are sent through the first and second pins of the VCU, a fault exhaust path is formed, and the vehicle is braked by exhausting through the exhaust port of the parking memory valve. This system can automatically brake the vehicle in the event of a VCU failure, thereby improving the safety of vehicle operation.
New Energy Vehicle Control System, Method, Device, Controller, Vehicle, and Medium
Patent Number: CN116252626B
Abstract: This application discloses a new energy vehicle control system, method, device, controller, vehicle, and medium. It is applied in the field of new energy vehicle technology to address the issues of poor adaptability and low efficiency in existing new energy vehicle control systems. Specifically, when the underlying control system determines that the new energy vehicle is in a low-power state, it puts the data interaction system and application control system into sleep mode. When the new energy vehicle is not in a low-power state, it puts the data interaction system and application control system into wake-up mode. The data interaction system receives vehicle control instructions sent by the overall vehicle control system and forwards them to the application control system. If the application control system determines that the vehicle control instructions are for driving control, it controls the high-voltage system operation and supplies power to the low-voltage system based on the driving control instructions. If the application control system determines that the vehicle control instructions are for operation control, it controls the operation of the upper-mounted system based on the operation control instructions.
Vehicle Driving Control Method and System
Patent Number: CN116605067B
Abstract: This invention discloses a vehicle driving control method and system, belonging to the field of automotive control technology. In the absence of a gearshift lever, accelerator pedal, and brake pedal, the gear information is sent to the Vehicle Control Unit (VCU) via a CAN bus by an external controller. After the VCU interprets the gear information, it matches the corresponding vehicle state and sends the corresponding state to the motor controller via the CAN bus, enabling the motor to operate in the corresponding mode. This invention utilizes a special cruise control function and an Electronic Brake System (EBS) controller to achieve the vehicle’s driving and braking functions. It also employs a gear lock protection mode to protect the motor during direct switching between Drive (D) and Reverse (R) gears. Furthermore, it incorporates an emergency braking mode that utilizes a parking memory valve controlled by the VCU to achieve emergency braking in the event of VCU failure, thus preventing occurrences of vehicle control accidents.
Vehicle Integrated Fusion Thermal Management System and Method
Patent Number: CN116619983B
Abstract: This invention discloses a vehicle integrated fusion thermal management system and method, which belongs to the field of vehicle control technology. The system includes a VCU, a thermal management information parsing module, a thermal management strategy matching module, and a thermal management fault detection module. Through the VCU, this invention controls all thermal management systems to achieve different heat dissipation modes for the motor and controller under different operating conditions, as well as different cooling requirements under different conditions. This system enables real-time fault diagnosis, fault localization, and fault handling for the complete thermal management system. Compared to the previous non-integrated systems that were not fully controlled by the VCU for fault diagnosis and localization, this invention improves the efficiency of fault diagnosis and handling, reduces overall vehicle costs, and enhances market competitiveness.
