Embodiments of the present invention provide a method, device, device, storage medium and system for adjusting an accelerator opening signal. By receiving the accelerator opening signal value sent by the accelerator pedal position sensor; if the accelerator opening signal value is greater than or equal to the preset accelerator If the opening safety threshold is set, the change value of the longitudinal displacement of the main driver’s seat sent by the main driver’s seat position sensor is obtained; if the change value of the longitudinal displacement of the main driver’s seat is equal to the preset longitudinal displacement safety threshold, the current control instruction is generated, and the The accelerator opening signal value of the control command is the accelerator opening signal value corresponding to the change value of the longitudinal displacement of the main driver's seat that has occurred closest to the change value of the longitudinal displacement of the main driver's seat and is smaller than the preset longitudinal displacement safety threshold ; According to the throttle opening signal value of the control command, the vehicle is controlled to avoid the phenomenon of "rushing or stalling" of the vehicle, and eliminate hidden dangers of driving safety, thereby ensuring the safe driving of the driver.

The present invention provides a holographic projection method, system and automobile, the method comprising: if a holographic projection start command is received, then acquiring the current driving speed of the automobile; if the current driving speed of the automobile does not exceed a preset threshold, the display data of the preset hologram is acquired and displayed on the preset hologram display. In order to solve the problem that the application of 3D holographic projection in the automotive field cannot be effectively coordinated with driving safety in the prior art.

The embodiment of the invention discloses a vehicle failure detection method, device, vehicle and storage medium. The method includes: obtaining the on-state of the vacuum pump, the state of the brake pedal, the vacuum pressure of the vacuum pump sensor, and the ambient pressure of the environmental sensor; determining a preset pressure change trend according to the on-state of the vacuum pump and the state of the brake pedal, and The vacuum pressure and the pressure change trend detect the failure of the vacuum pump sensor; when the vacuum pump sensor is in a normal working state, obtain the pre-stored limit pressure of the vacuum pump, and detect the failure of the environmental sensor according to the limit pressure and the environmental pressure. The technical solution of the embodiment of the present invention realizes the failure of the vacuum system when the voltage of the vacuum sensor is in the normal range, improves the accuracy of the failure detection of the vacuum pump system, and can enhance the safety of the vehicle.

The present invention provides a car panoramic view system, method and car, the system includes: a system, the system includes: a processor, used to obtain the change value of the car's driving slope, and if the change value of the slope exceeds the preset first Threshold, then send the surround-view image angle adjustment instruction to the surround-view controller; the surround-view controller is used to adjust the angle of the camera unit to collect images according to the surround-view image angle adjustment instruction; the camera unit is used to collect images around the vehicle and send to the human-computer interaction display interface; the human-computer interaction display interface is used to display the surround-view image collected by the camera unit. It solves the problem in the prior art that when the vehicle is driving on a steep road, the driver cannot see the road conditions ahead but only the sky, causing the front view to be in a blind spot and causing safety risks.

The invention discloses a powder metallurgy brake shoe structure and a machining method thereof. The brake shoe structure comprises a back plate, a steel backing, a friction body and a shoe back component. The back plate is fixed to the arc in the shoe back component, the steel backing is located on the inner arc of the back plate, and the friction body is fixed to the steel backing. The shoe back component is composed of a shoe back body, arc check blocks, boss locating pins and a curved shoe nose, the arc check blocks, the boss locating pins and the curved shoe nose are arranged on the shoe back body, and the arc check blocks, the boss locating pins, the curved shoe nose and the shoe back body are integrated. A weld joint formed by welding the steel backing and the shoe back body on a brake block in the middle of a brake shoe is connected with weld joints formed by welding the steel backing and the shoe back body on brake blocks on the two sides of the brake shoe into a whole, the situation that in the frequent brake process of a currently-used shoe brake on a locomotive, weld joints of welding parts crack, and especially weld joints crack and even fall off in the welding process of a shoe brake nose on the brake shoe can be avoided within the service life of the shoe brake, and potential running safety hazards are eliminated.
