The invention relates to a control method of an automatic driving vehicle. The method comprises the following steps of when a to-be-driven road section of the vehicle is confirmed to contain a bridgeopening, judging a lane where the vehicle is positioned, and taking the corresponding measures, such as lane changing, deceleration, etc., in advance according to the condition of the lane, so that the vehicle can safely and stably pass through the road section.

The invention discloses a speed bump for a sponge city, which comprises a water storage tank and a speed bump body. The water storage tank is buried in a soil layer, and a contraction groove is opened on the upper end of the soil layer. A plurality of shrinkage grooves are inserted at the bottom of the shrinkage groove The seepage pipe connected with the interior of the water storage tank, the bottom of the contraction groove is provided with a support mechanism for supporting the speed bump body, the upper end of the speed bump body is provided with a movable groove, and the inner wall of the movable groove is slidably connected with a pressing plate, A water spray chamber is opened inside the speed bump body. The advantage is that when the vehicle passes the body of the speed bump, it will squeeze the pressing plate to move downward, so that the hydraulic oil in the squeeze box will be squeezed to push the push plate to move, and then the push plate will push the rainwater pressure in the box. Into the spray pipe, and finally the rainwater in the spray chamber is squeezed by the rainwater in the spray pipe and sprayed out from the spray hole, so as to realize the utilization of rainwater, and can reduce the ground temperature when the weather is hot, thereby improving the environment of the park. surroundings.

The invention discloses a self-propelled chassis with an adjustable transverse wheel tread and an adjustable ground clearance. The self-propelled chassis is composed of a frame, a front axle, a rear axle, a power system, a ground clearance adjusting system, a transverse wheel tread adjusting system and a steady adjusting and controlling system. The power system comprises an engine, a clutch, a pump station, a hydraulic motor, a proportional valve and the like. The ground clearance adjusting system comprises a controller, a servo valve, ground clearance adjusting hydraulic cylinders and the like, wherein the controller adjusts the four ground clearance adjusting hydraulic cylinders through the servo valve to synchronously ascend and descend to change the ground clearance of the chassis. The transverse wheel tread adjusting system comprises a servo valve, a controller, a wheel tread adjusting hydraulic cylinder and the like, wherein the hydraulic cylinder drives a piston rod according to an instruction of the controller, drives an axle shaft connecting piece to move through a connecting flange, pushes wheels to transversely move and adjusts the transverse wheel tread of the chassis. The steady adjusting and controlling system controls flows of the four ground clearance adjusting hydraulic cylinders respectively through the servo valve according to unsteady signals, collected by a gyroscope, of the front axle and unsteady signals, collected by the gyroscope, of the rear axle, and automatically adjusts balance and stability of the chassis.
