The electronic parking solenoid valve is a key component used to control the vehicle parking system. Its main design principles are as follows:
Electromagnetic principle: The electronic parking solenoid valve realizes hydraulic control inside the valve body by controlling the on and off of the solenoid coil. When the solenoid coil is energized, the generated magnetic field causes the valve core inside the valve body to move, changing the state of the hydraulic channel, thereby locking or releasing the brake system.
Hydraulic control: The electronic parking solenoid valve controls the hydraulic signal in the hydraulic system to lock and release the brakes. When the solenoid coil is energized, the valve core will open or close the hydraulic channel, allowing the pressure in the hydraulic system to be transmitted to the braking system, thereby controlling the parking state of the vehicle.
Control circuit: The control circuit of the electronic parking solenoid valve is usually controlled by the vehicle's electronic control unit (ECU). The ECU sends corresponding control signals to the electronic parking solenoid valve according to the driver's operation and the status of the vehicle, thereby controlling the parking system.
Key technologies or innovations may include:
Solenoid coil design: Optimize the design of the solenoid coil to improve the magnetic field generation efficiency and response speed to ensure the reliability and stability of the electronic parking solenoid valve.
Valve core structure optimization: By optimizing the design and material selection of the valve core, the inertia and friction of the valve core are reduced, and the movement flexibility and response speed of the valve core are improved, thereby improving the performance of the electronic parking solenoid valve.
Sealing technology: Use high-performance sealing materials and sealing structures to ensure the sealing performance and durability of the electronic parking solenoid valve in different working environments.
Intelligent control algorithm: Introduce an intelligent control algorithm to optimize the control strategy of the electronic parking system based on the vehicle's status and driver's operation, improving the performance of the parking system and driving safety.
Energy-saving technology: Optimize the working mode and energy consumption of the electronic parking solenoid valve, reduce the energy consumption level of the system, and improve the energy utilization efficiency of the vehicle.
Through the application of these key technologies and innovations, the electronic parking solenoid valve can better control the vehicle parking system and improve driving safety and comfort.
