Latest Patents

One of his latest patents is a "Motor rotation control method and device." This invention focuses on a technical field of motor control. The method involves conducting inverse Park transformation and inverse Clark transformation to control output results of a position loop, a speed loop, and a current loop to obtain SVPWM signals of a present cycle. It also includes decoupling an interrupt control cycle from a PWM signal reference channel, acquiring present position sampling information of a motor, and predicting the position sampling information to obtain position result information of a motor rotor in predicted cycles. An interrupt function trigger signal is added to realize decoupling from the PWM signal reference channel, ensuring that the SVPWM signal update frequency of motor control remains unaffected when CPU load is reduced by adding an interrupt function scheduling cycle.

Another notable patent is the "Protocol data bit parsing method and device for AK protocol wheel speed sensor." This method involves receiving a current signal sent by an AK protocol wheel speed sensor and converting it into a first voltage signal and a second voltage signal. It captures the time of rising edges and falling edges of these signals, saving them as timestamp sets. The complete set of timestamps of protocol data bits is acquired and parsed to obtain values of the protocol data bits. This method can reduce product costs and ensure the safety of the supply chain, thereby improving the competitiveness of enterprises.
