Embodiment Construction
[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.
[0019] Such as Figure 1-5 As shown, the present invention is an automobile idling start-stop system with braking energy recovery, including a BSG motor 1 and a DCDC converter 5 connected to the automobile engine. The BSG motor 1 is a belt-driven starter-generator integrated machine. The BSG motor 1 is connected to the automobile engine through a belt, and the BSG motor 1 is connected to the controller 4 through a three-phase wiring harness 3 for power transmission. The controller 4 receives the vehicle speed, neutral gear, clutch, and temperature through the control wiring harness 2 port In. Signal to determine, control the start and power generation of the BSG...

The invention provides an automobile idle speed start-stop system with a braking energy recovery function. The automobile idle speed start-stop system comprises a BSG motor connected with an automobile engine and a DCDC converter. The BSG motor is connected with a controller through a three-phase wire bundle to conduct electric energy delivery. A control wire bundle is connected between the controller and the BSG motor. The DCDC converter is provided with three ports, namely, the positive electrode port A, the positive electrode port B and the negative electrode port. The positive electrode port A on the DCDC converter is connected with the positive electrode port of the controller. The positive electrode port B on the DCDC converter is connected with the positive electrode of an automobile battery. The positive electrode port of the controller is connected with the positive electrode port of a super capacitor. The negative electrode port of the DCDC converter, the negative electrode port of the super capacitor and the negative electrode port of the controller are connected to the negative electrode port of the battery. By means of the automobile idle speed start-stop system, the starting frequency of an automobile starter is decreased, battery loss caused by large current in the starting process is avoided, the starter and the automobile battery do not need to be enhanced, cost is reduced, and energy can be stored in the super capacitor when the automobile is braked so that energy recovery can be achieved.
Description
Technical field [0001] The invention belongs to the field of automobile control devices, in particular to an automobile idling start-stop system, particularly an automobile idling start-stop system with braking energy recovery. Background technique [0002] With the rapid increase in the number of automobiles, automobile fuel consumption and emissions have attracted more and more attention. Congested urban roads make idling vehicles continue to consume fuel and emit exhaust gas. The existing start-stop system is mainly realized by an enhanced starter. Frequent use leads to a decrease in the performance and life of the starter and battery, and increases the economic cost of the car. The existing start-stop system has limited reduction in fuel consumption and cannot recover excess energy to save energy more effectively. Summary of the invention [0003] In order to solve the above problems, the present invention provides an automobile idling start-stop system with a super capacito...
