Embodiment Construction
[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0020] Such as figure 1 and 2 The shown hydrogen fuel cell four-wheel hub motor drive plug-in controller includes a processor 1, an angular velocity measurement module 2, a triaxial acceleration measurement module 3, a digital signal input module 5, an analog signal input module 6 and a digital high-side output module 8. Among them, the processor 1 can independently perform the self-inspection of the CPU unit, the clock unit, and the storage unit. When a failure occurs, a response interruption will be generated and the application program will be notified for processing. The angular velocity measurement module 2 is used to measure the real-time yaw angular velocity and pitch of the vehicle. Angular velocity and rolling angular velocity, the three-axis acceleration measurement module 3 is used to measure the real-time lateral acceleration, longi...

The invention discloses a hydrogen fuel cell four-wheel hub motor drive external controller which comprises a processor, an angular velocity measurement module, a three-axial acceleration measurement module, a digital signal input module, an analog signal input module and a digital high-side output module, and is characterized in that the functions of a hub motor differential torque control TVCU and a vehicle control unit VCU are separated; the requirement for computing resource consumption of a controller chip is reduced, and the cost of the differential torque controller is saved; the functions of the controller are separated, so that the load unbalance risk on the CAN network is reduced; the control containing two control functions does not need to be developed again, and the development period is shortened; and the differential torque control of a hydrogen fuel cell full-power four-wheel hub motor driven automobile and a control function of the seamless integration of a whole automobile controller are realized for the first time.
Description
technical field [0001] The invention relates to the technical field of in-wheel motors, in particular to a hydrogen fuel cell four-wheel in-wheel motor-driven external controller and a control method. Background technique [0002] At present, hydrogen fuel cell full-power in-wheel motor distributed drive new energy vehicles all adopt the design method of redeveloping the vehicle controller and embedding in-wheel motor distributed drive torque vector control. In this design method, in-wheel motor distributed drive Torque vector control involves vehicle multi-body dynamics analysis and complex algorithm development and calculation, which consumes a lot of controller chip resources. In order to improve the chip computing capability of the vehicle VCU (Vehicle control unit, vehicle controller), it is necessary to increase the The cost of the controller; and integrating the vehicle controller and the torque vector controller into one controller increases the load pressure on the ...
