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.

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 application discloses a method, apparatus, device, and storage medium for enhancing the power of range-extended vehicles, belonging to the field of vehicle control, and can solve the problem that range-extended vehicles cannot increase acceleration when the battery is low. The method includes: real-time acquisition of the target vehicle's battery charge, accelerator pedal opening, accelerator pedal opening rate of change, vehicle speed, and battery cell temperature; determining a comprehensive power demand intensity index based on the accelerator pedal opening, the accelerator pedal opening rate of change, the vehicle speed, and the acceleration request value; determining whether the target vehicle meets the enhancement mode activation conditions based on the battery charge, the comprehensive power demand intensity index, the battery cell temperature, and the battery health; and, if the target vehicle meets the enhancement mode activation conditions, entering enhancement mode and adjusting the target vehicle's drive power to a first drive power to enable the target vehicle to reach the target speed.

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.
