Description
Technical Field
The present application relates to the field of automotive technologies, and in particular, to a remote starting method and a remote starting apparatus for a vehicle.
Background
The domestic tractor mostly adopts the diesel engine technology, and the diesel engine is a compression ignition engine, and compresses the mixture of fuel oil and air by utilizing the lower self-ignition point of diesel oil, so that when the temperature rises to reach the self-ignition point, the fuel oil-gas mixture pushes a piston to move to do work.
When the tractor heavy truck is started, besides common manual starting, one-key starting and remote starting are also carried out. For one-key starting, outputting power within a set fixed starting time, then judging whether the rotating speed of the engine reaches a preset rotating speed, and if so, stopping starting; if not, the output is continued, a fixed time is waited, and after the timing is finished, no starting signal is output no longer no matter whether the starting is successful or not. In this mode, the driver can actively interrupt the start-up process by operating the button according to the vehicle state. For remote start, the vehicle receives a start command from the cloud and starts the engine through the one-touch start system described above. At this time, the vehicle performs the start operation according to the logic of one-key start, but the driver cannot know whether the vehicle is successfully started due to the remote operation.
The tractor heavy truck is mostly used for long-distance logistics, so the external environment where the vehicle is located in the long-distance transportation process has large change. However, based on the above-mentioned remote start strategy, the fixed start time cannot meet the start requirement under all environments. For example, building doors belong to a tropical environment and are kept at relatively high temperatures throughout the year, failure to start the building doors within a fixed starting time may be a failure, and the engine may operate in a failure state for a long time, which may cause serious vehicle damage. However, in desert rivers, the weather is often low at about-30 degrees, and the fixed starting time may not guarantee the successful starting, so that the engine is frequently started by trying, and the power loss of the vehicle is caused.
In summary, in the prior art, the influence of the external environment of the entire vehicle on the remote start of the vehicle is ignored, so that the vehicle does not work in the optimal state.

As an example, the second threshold is 10 ℃, and if the ambient temperature is higher than 10 ℃, the start-up base time t0 is taken as the start-up time. If the ambient temperature is below 10 ℃, the start-up time is increased by 1s (first unit compensation time) every 1 ℃ (first predetermined temperature interval). If the ambient temperature is 0 ℃, the difference between the ambient temperature and the second threshold is 10 ℃, and the first quotient is 10, the first compensation time is 10 s.

P3: and judging whether the defrosting is finished or not after the preset time (for example, 10min) is reached. If not, return to P2. If yes, the air conditioning system is closed, and the process is ended.
As one embodiment, the image of the front windshield is collected through a camera in the cab, and whether defrosting is finished or not is judged through an image processing result.
