The intelligent water draining system is arranged under the road surfaces, so that the intelligent water draining system is not damaged by people easily.

This application discloses a method and system for recovering energy from vehicle coasting. The method first calculates the initial feedback torque of the motor according to the current speed of the vehicle and the calibrated coasting deceleration, and then calculates the initial feedback torque according to the temperature and state of charge of the battery. Get the constrained feedback torque of the battery, and then calculate the constrained feedback torque of the motor according to the speed of the motor, and finally select the one with the smallest absolute value among the initial feedback torque of the motor, the constrained feedback torque of the battery and the constrained feedback torque of the motor As the final feedback torque of the motor, and use the final feedback torque of the motor to recover the sliding energy of the car. Compared with existing technologies, this method not only ensures driving comfort, but also maximizes the recovery of coasting energy.

The invention discloses an inter-groove apron board for improving vortex vibration performance of a double-amplitude bridge, the double-amplitude bridge comprises two main beams, each main beam extends along the bridge direction, the two main beams are arranged side by side along the transverse bridge direction, an open groove is arranged between the two main beams, the inter-groove apron board is arranged at the open groove, and the inter-groove apron board extends along the vertical direction. The invention also provides the double-amplitude bridge. The inter-groove apron board is vertically fixed between the upstream main beam and the downstream main beam, vortexes of wake flow of the upstream main beam are prevented from falling off and acting on the downstream main beam, the vortexes are isolated, and vertical excitation of the section of the bridge is reduced, so that the situation that the downstream girder generates large-amplitude vibration is avoided, the pneumatic interference effect between the upstream girder and the downstream girder is effectively reduced, double-amplitude bridge vortex vibration is eliminated, the driving comfort and safety are ensured, the section form of the main beam does not need to be adjusted, the structural cost is reduced, main beams with different sections can be adapted to, and the application range is wide.

The invention relates to a multifunctional automobile seat adjusting handle convenient to assemble and disassemble, which is used for adjusting the front and back of an automobile seat and the inclination angle of a backrest.
