Disclosed are an inertial-sensor-based wearable hemiplegia rehabilitation apparatus and a strap-down attitude algorithm. The inertial-sensor-based wearable hemiplegia rehabilitation apparatus mainly comprises an upper computer and an inertia measurement system. Inertia measurement units distributed on different body parts of a patient acquire attitude angle information of the patient moving, through inertial sensors; the attitude angle information is transmitted to the upper computer through a wireless transmission module; the upper computer tracks the rehabilitation training process of the patient in real time according to the attitude angle information of different positions. The invention further provides a strap-down attitude algorithm based on plane constraint. According to the method, a restraint plane is established according to previous-moment motion attitudes of a forearm and a postbrachium during moving, the restraint plane is used to restrain acceleration information, systematic self-restrained measurement is achieved accordingly, and angle measurement is better in stability and accuracy. The inertial-sensor-based wearable hemiplegia rehabilitation apparatus and the strap-down attitude algorithm have the advantages that accurate rehabilitation motion attitudes and accurate amount of motion can be provided according to conditions of the patient with hemiplegia, degree and times of completing each set of moves are recorded for the patient, and a function of simple evaluation on hemiplegia and treatment effect for the patient with hemiplegia is provided.

The invention relates to a vehicle control unit for a pure electric vehicle. A vehicle control board with an ARM9S3C2440 master module and multi-site CAN (Controller Area Network) bus communication are adopted, and a power management system and a motor controller are combined to form a vehicle CAN control communication network. The vehicle body status monitoring, driver intention analysis, energy status monitoring, fault alarm monitoring, and vehicle running guarantee functions and the like are realized. The control unit is integrated with the status information of various parts such as an acceleration pedal, a brake pedal, a vehicle-mounted energy source and a driving motor to decide the currently taken control strategy; the warning forecast of the fault in the movement process of the vehicle is carried out; and when the vehicle decelerates and brakes, the whole power and an energy storage system work in an energy feedback status by control instructions. Meanwhile, the multi-site CAN bus technology is used, so that the stability of the whole control unit is substantially improved, and the cost is effectively saved.
