This utility model discloses a mechanical steering gear for preventing abnormal noise. This utility model relates to the field of automotive parts technology. The mechanical steering gear for preventing abnormal noise includes a housing mechanism. The main body of the housing mechanism is a box structure with a one-way opening at the top. A positioning rod is fixedly connected inside the housing mechanism. The positioning rod is arranged longitudinally. This utility model effectively prevents dust from entering the interior through multiple sealing protections of components such as the housing mechanism, cover mechanism, insert plate assembly, plunger, and its sealing ring. This reduces wear caused by dust friction between the rack assembly and gear assembly, thereby reducing the possibility of abnormal noise. The reasonable design of components such as the positioning rod, connecting plate, and positioning pin ensures stable power transmission from the input shaft to the output rod, making tire steering reliable. On the other hand, the good sealing structure reduces component wear and extends the service life of the steering gear.

The application can accurately control the entry time of the neutral and off coasting by predicting the coasting time to ensure the economic benefit, and can realize the maximization of the neutral and off coasting benefit under the premise of guaranteeing the vehicle driving safety and driving experience by combining the multi-dimensional safety state monitoring.

A CVT speed ratio optimization control method and system includes the following steps: Step 1) Using the current speed ratio of the vehicle as a benchmark, calculate the corresponding comprehensive efficiency based on the speed ratio under different search directions, compare the comprehensive efficiency under different search directions, and determine the optimal search direction; Step 2) In the optimal search direction, continue to adjust the current speed ratio according to different search step sizes, and calculate the corresponding comprehensive efficiency value respectively. The speed ratio corresponding to the maximum comprehensive efficiency value is the target optimized speed ratio; Step 3) Determine whether using the target optimized speed ratio affects the vehicle's backup driving force. If it does not affect it, control the current CVT speed ratio to become the target optimized speed ratio; if it does affect it, do not optimize the current speed ratio. This invention can improve the overall efficiency of the vehicle without complex offline calibration, improving energy economy while ensuring the user's driving experience.

This invention discloses an adjustable light-transmitting automotive windshield system and automotive product. This invention allows for a reduction in the light transmittance of only the adjustable light-transmitting area unit within the control area, while maintaining a high light transmittance for the adjustable light-transmitting area units outside the control area. This weakens the intensity of strong light sources observed by the driver, reducing glare and discomfort caused by intense light emitted from external light sources, thus improving the driving experience and safety. Furthermore, this invention allows for the blocking of strong light from all directions, improving the ability to block strong light and reducing adverse consequences such as limited driver visibility caused by improper blocking. Moreover, the adjustable light-transmitting automotive windshield system operates without driver intervention, reducing the possibility of driver distraction and ensuring driving safety. This invention has wide applications in the automotive technology field.

This invention discloses a control method and a control device. The control method includes: entering a first execution gear stage and determining a first target gear at this stage; acquiring execution information of the previous first target gear, including target position, drive duty cycle, and actual position; if the first position difference between the preset optimal position of the first target gear in the first execution gear stage and the actual position of the previous first target gear exceeds a first execution gear threshold, correcting the target position or drive duty cycle of the current first target gear; the previous first target gear and the current first target gear are in different first execution gear stages. In this invention, when the gear shifting control accuracy of the previous gear shifting operation is low, the control accuracy of the current gear shifting operation can be improved by correcting the target position or drive duty cycle of the current first target gear, thereby increasing the success rate and accuracy of gear shifting and ensuring the driver's driving experience.
