The invention discloses a method for starting a hybrid sedan. The method has the characteristics that the cost is low, the control device is simple, the performance is reliable and the like. The method comprises the following steps that: a sedan control unit is connected with a battery management system, an engine control unit, a motor control unit and an instrument through a communication bus; a mechanical ignition lock is arranged; an automatic combustion control (ACC) gear of the mechanical ignition lock is connected with an assistant electrical appliance part in the sedan, an IG gear of the mechanical ignition lock is connected with electrical parts required during running, a START gear of the mechanical ignition lock is connected with one end of an ignition relay coil, and the other end of the coil is grounded through an output port of the sedan control unit; one end of a normally opened contact of the ignition relay is grounded, and the other end of the normally opened contact of the ignition relay is connected with an input port of the sedan control unit; and power of all the electrical appliances in the sedan is cut off by the mechanical ignition lock on the OFF gear.
Description
technical field [0001] The invention relates to a starting method for a hybrid electric vehicle, in particular to a starting method for a hybrid electric vehicle. Background technique [0002] In a traditional car, the power is provided by the engine, so only by starting the engine can the vehicle be powered. The start of the car engine is mainly controlled by the mechanical ignition lock. When the IG gear is turned on, the working power of all electrical appliances is turned on and is in a working state; when the START gear is turned on, the starting relay is turned on, and the starter works to drag the engine to ignite to start the engine; after the engine starts, the ignition lock The key returns to the IG gear, and the engine starting process ends. [0003] In the current gasoline-electric hybrid new energy vehicles, the power is divided into two parts, one part is still powered by the traditional engine, and the other part is powered by the motor / generator, and the pow...
