Disclosed is a creep control system and method for a hybrid vehicle, which controls the driving of a motor according to the distance to a preceding vehicle in order to provide creep driving when the hybrid vehicle has come to a complete stop. In particular, driving information is detected and a determination is made as to whether the hybrid vehicle is in an idle stop and completely stationary state. Then when the hybrid vehicle is in the idle stop and completely stationary state, a determination is made as to whether a distance from a preceding vehicle is more than a predetermined distance. When the distance to the preceding vehicle is more than the predetermined distance, a motor is driven to perform creep driving.

A wide area surround view monitoring apparatus for a vehicle includes: a camera module installed in an ego (self-driving) vehicle, and configured to acquire a surround image, wirelessly transmit the acquired surround image, wirelessly receive a camera image from a neighboring vehicle to measure RSSI, and transmit the RSSI with the surround image of the ego vehicle and the camera image of the neighboring vehicle through a vehicle network; and a controller configured to receive the surround image of the ego vehicle, the camera image of the neighboring vehicle and the RSSI from the camera module, determine and output a possibility of collision with the neighboring vehicle, configure a wide area SVM view by synthesizing the surround image of the ego vehicle with the camera image of the neighboring vehicle, and generate a local wide area image map by calculating a possible driving space of the ego vehicle.

A tire angle change motor steers a host vehicle according to a tire angle corresponding to the rotation angle of a steering wheel detected by a steering wheel angle sensor. A gear ratio calculating unit of a tire angle control unit changes the amount of steering corresponding to the rotation angle of the steering wheel required for the tire angle change motor to steer the host vehicle, depending on the amount of pushing of the steering wheel detected by the pushing amount sensor. Therefore, it is possible to improve the convenience of a driving operation for steering. A pushing direction reaction force motor changes a reaction force generated against the amount of pushing of the steering wheel by the driver, depending on the speed of the host vehicle detected by a vehicle speed sensor. Therefore, the reaction force makes it possible to prevent the host vehicle from being steered by an unintended operation of the driver in various traveling states of the vehicle.

The invention discloses a vehicle shifting method. The method comprises the following steps: moving a shifting power input component to input a shifting instruction; acquiring gear information input by the shifting power input component which is moved, and transmitting the gear information to an automobile electronic control unit to carry out processing; and outputting the shifting instruction by the automobile electronic control unit, and controlling an automobile power output end to execute a shifting operation. The method is characterized in that two signal acquisition manners such as electromagnetic induction detection and mechanical contact type detection are adopted to acquire the gear information input after moving the shifting power input component, and during the processing of the automobile electronic control unit, the shifting instruction is output after comparing and verifying the two pieces of acquired gear information. The method disclosed in the invention has the advantages of being simple to implement, improving the safety, improving the shifting operation reliability, and improving the driving convenience and facilitating the fault handling under the condition that the automobile safety risk is reduced.

The invention provides a vehicle control method and device, control equipment and a vehicle, and the control method comprises the steps: controlling the vehicle to enter a crawling mode and monitoringthe stroke of a push rod of a main cylinder when the vehicle is started; when the stroke of the main cylinder push rod is changed and the vehicle speed is reduced to 0, the current first moment and the first stroke of the main cylinder push rod are obtained, and the stroke of the main cylinder push rod continues to be monitored; when the main cylinder push rod stroke is smaller than the first stroke, controlling the vehicle to run; when the stroke of the main cylinder push rod is larger than the first stroke, judging whether the vehicle meets the short-term parking activation condition, and when the short-term parking activation condition is met, controlling the vehicle to exit from the creeping mode and enter the short-term parking mode; wherein the short-term parking activation condition at least comprises that an accelerator pedal is not stepped down; the current vehicle speed is 0; the time interval between the current moment and the first moment is greater than a preset first duration threshold; and the main cylinder push rod stroke between the current moment and the first moment is greater than 0. According to the method, crawling and other modes can be started only throughthe brake pedal, and operation is easy.

The invention provides an interval transmission misoperation-preventing device for a commercial vehicle to smoothly shift from a low-speed gear to a high-speed gear during the interval transmission process of the multi-gear manual transmission of the commercial vehicle based on the driving information of the commercial vehicle. The interval transmission misoperation-preventing device for the commercial vehicle comprises a first switching valve 100 provided with a working pressure application port in linkage with an interval switch 54 on a gear-shifting handle 50 to realize the switching of ports; a shut-off valve 110 provided with a working pressure application port to realize the switching of ports during the transmission process shifting in the transmission mode 56 of the gear-shifting handle 50; a second switching valve 120 in linkage with the interval switch 54 to realize the switching of ports; an interval actuator 130 used for realizing the interval transmission based on the working pressure provided by the port of the second switching valve 120; and a safety control valve 140 used for limiting a working pressure signal from the first switching valve 100 to the second switching valve 120 through receiving a blocking signal based on the vehicle speed information.

The invention discloses an LNG (Liquefied Natural Gas) pressurization control system. Liquefied natural gas is stored in an LNG storage tank, and the liquefied natural gas is converted into gaseous natural gas through a vaporizer device and stored in a first gaseous natural gas buffer tank; a pressure sensor detects the air pressure of a second gaseous natural gas buffer tank and sends the air pressure to a pressurization control device; when the pressurization control device detects that the received air pressure is smaller than a preset minimum value, the gaseous natural gas in the first gaseous natural gas buffer tank is pumped into the second gaseous natural gas buffer tank, and when the air pressure of the second gaseous natural gas buffer tank reaches the air pressure for starting the natural gas engine, a natural gas engine is started; and when the pressurization control device detects that the received air pressure is larger than a preset maximum value, the pressurization control device stops working.
