Abstract

The invention discloses a current vortex retarder, a generation / start integrated system and a control method thereof in the automobile field. A magnetoelectric machine and a current vortex retarder are arranged in a flywheel casing, an input shaft penetrates through the center of the flywheel casing and fixes the current vortex retarder and the magnetoelectric machine, and a control unit is arranged outside the flywheel casing and is respectively connected with the current vortex retarder, the magnetoelectric machine, a revolution speed transducer, a torque transducer and an accumulator. The control unit monitors the revolution speed of the input shaft to control coils of the current vortex retarder to be electrified so as to start an engine; the control unit also collects the current revolution speed and torque of the input shaft and the wheel speed signals of wheels, calculates the PWM value, and controls the size of the electrified electric current of the current vortex retarder so as to retard the engine. The generation / start integrated system is an intelligentized integrated system which integrates a start system, a generation system and a brake system, thereby reducing the weight. Besides, the produced current vortex brake moment can brake the engine so as to achieve the purpose of recovering the energy, prolong the service life of the accumulator and improve the stability of the brake system.

Description

technical field

[0001] The invention relates to the field of automobiles, in particular to a starting system, a power generation system and a braking system of the automobile. Background technique

[0002] The traditional car starting system consists of a battery, ignition switch, starter relay, starter, etc. When the ignition switch is turned on to the STA gear, the starter relay is connected to the starting circuit to provide a large starting torque, and the battery needs to provide a large current to the starter rotor. The biggest disadvantage of the armature winding is: when there are factors that cause the engine to fail to start normally, if the driver frequently puts the ignition switch in the STA position, it will not only consume a lot of battery energy, but also seriously affect the use of the battery. life, or even damage the battery.

[0003] The traditional automotive power supply system uses an alternator as a power generation device. Due to the limited output...
