The invention belongs to the technical field of vehicle engines, and particularly relates to a start and stop control method and a cooling control device of an engine in a vehicle. The start and stopcontrol method of the engine in the vehicle includes the following steps: acquiring first reunion time of a pneumatic clutch and first separation time of the pneumatic clutch when a gas bottle is in afilled state; acquiring second reunion time of the pneumatic clutch and second separation time of the pneumatic clutch in the use process of the air bottle; and controlling the engine to start and drive a compressor to inflate the air bottle according to the rule that the second reunion time of the pneumatic clutch is larger than the first reunion time and larger than first safety time, and the second separation time of the pneumatic clutch is larger than the first separation time and larger than second safety time. The start and stop control method of the engine in the vehicle judges currentpressure status of the air bottle through the separation time of the pneumatic clutch and the reunion time of the pneumatic clutch, and controls the engine in the vehicle to start and stop so as to inflate the air bottle.
Description
technical field [0001] The invention belongs to the technical field of vehicle engines, and in particular relates to a start-stop control method and a control device for an engine in a vehicle. Background technique [0002] When refitting old new energy vehicles, sometimes some technical data are missing. For example, the protocol version of the instrument is too old, and the VCU (English name: Vehicle Control Unit, Chinese name: Vehicle Control Unit) cannot analyze the instrument or body. The air pressure message sent by the controller, or the model of the air pressure sensor cannot be obtained, and the VCU cannot accurately analyze the signal of the air pressure sensor. [0003] In existing hybrid vehicles, the air compressor is driven by the engine. After the engine is started, the air compressor is driven to fill the compressed air system storage cylinder with compressed air to establish a stable working pressure. In order to ensure the normal operation of the vehicle, t...
