This invention provides a vehicle field of view expansion display method, device, vehicle, and storage medium. The method is applicable to the vehicle control center in a vehicle vision assistance system. The vehicle vision assistance system also includes a field of view acquisition device and a field of view display device connected to the vehicle control center. The field of view acquisition device is installed on the vehicle and located in the vehicle's blind spot. The method includes: real-time acquisition of the vehicle's speed, system resource information, the field of view display resolution of the field of view display device, and the field of view image sent by the field of view acquisition device; determining the display frame rate of the field of view image based on the vehicle speed, system resource information, and field of view display resolution; and sending the field of view image to the field of view display device for display at the specified frame rate. This method of expanding the driver's field of view by installing a field of view acquisition device in the vehicle effectively eliminates the driver's blind spot, thereby ensuring safe driving.

This utility model belongs to the field of intelligent connected vehicle safety alarm technology, and particularly relates to an intelligent connected vehicle safety alarm device, including a fixing plate. In this intelligent connected vehicle safety alarm device, limit blocks are fixedly connected to both sides of the fixing plate, a protective frame is provided on the top of the fixing plate, and a dustproof and heat dissipation component is provided on the side of the protective frame. By setting the dustproof and heat dissipation component, a slider first slides inside a groove, thereby driving the dustproof net inside the mounting plate to move up and down. Then, a second movable block moves up and down on top of the first movable block. When the dustproof net is closed, a locking block is engaged in a rectangular groove, and under the action of a spring, a limiting rod is engaged inside the groove, thus fixing it. Conversely, it can be disassembled and cleaned regularly, which can reduce the occurrence of such problems from the source and provide strong protection for the safe driving of intelligent connected vehicles.

A vehicle control method and apparatus, belonging to the field of vehicle technology, are disclosed. During the travel of a first vehicle in a first lane, a second vehicle traveling in a second lane is determined based on the position of the first vehicle at a first moment. The positions of the second vehicle at multiple moments are predicted based on the position of the second vehicle at the first moment. Based on the center line of the second lane and the positions of the second vehicle at these multiple moments, the potential lane-changing behavior of the second vehicle is predicted. If a potential lane-changing behavior of the second vehicle is determined, the first vehicle is controlled to steer away from the second vehicle. This application can predict in advance whether the second vehicle may change lanes, thereby controlling the first vehicle to steer and avoid obstacles in advance, thus improving the effectiveness of obstacle avoidance.

This invention discloses a method, apparatus, device, and vehicle for handling battery temperature sampling disconnection faults. When a battery temperature sampling disconnection fault is detected in the power battery system, the number of disconnected temperature sampling lines is obtained. When the number of disconnected lines is less than or equal to a preset number, the current highest temperature of a single cell in the power battery is detected. When the difference between a first temperature fault threshold and the current highest temperature of a single cell is greater than or equal to a first preset temperature, the current lowest temperature of a single cell in the power battery is detected. When the difference between the current lowest temperature of a single cell and a second temperature fault threshold is greater than or equal to a second preset temperature, it is determined whether the current highest and lowest temperatures of a single cell are within a preset temperature range. When it is determined that both the current highest and lowest temperatures of a single cell are outside the preset temperature range, the charging and discharging current is limited to a first preset current value. This method can ensure the normal and safe operation of the vehicle and balance system safety and operational efficiency.
