4results about How to "Simplify the wiring harness" patented technology

This invention discloses a plug-in board and adapter, associated electrical components, and an electric vehicle. The plug-in board includes an MCU circuit I, an adapter communication circuit, and a controller circuit. Some models also include a BMS battery management circuit, a vehicle electrical and electronic fuse circuit, a taillight control circuit, a communication line starting power supply circuit, a human-machine interaction circuit, and a battery communication circuit. The plug-in board is soldered to the controller's PCB circuit board via pins, or connected to the pins on the controller's PCB board via a socket. The plug-in board and the controller are housed in a single housing, saving space, material costs, and labor costs. The original controller's MCU chip can be improved to enhance controller performance and enable the application of bus control systems without modification, greatly simplifying the wiring harness and connectors throughout the vehicle.

The invention belongs to the related technology of a vehicle-mounted system, and particularly relates to an intelligent driving control method, a vehicle-mounted device and a vehicle machine system. According to the method, a system mark value is set, a current system is determined according to the system mark value, first configuration information is acquired, connection is established between the current system and idle acquisition equipment according to the first configuration information, and the current system acquires acquisition data through the acquisition equipment; and continuously monitoring the system mark value, when the system mark value changes, re-determining the target system of the current vehicle, and establishing connection between the target system and the idle acquisition equipment. Through the above mode, the vehicle acquisition equipment, such as the image acquisition equipment, can determine different connection systems according to the system mark values, and multiple systems share one acquisition equipment, so that the use of the equipment is reduced, the wiring harness is simplified, and the layout complexity is reduced.

The embodiment of the utility model discloses a combinable modular multi-way proportional valve amplifier and an electro-hydraulic proportional hydraulic system, and the combinable modular multi-way proportional valve amplifier comprises an expansion unit which comprises a plurality of expansion modules which are connected in series and are used for respectively driving and controlling each joint of a proportional multi-way valve; and the basic module is connected in series with the expansion units so as to transmit electric energy and bus signals to each expansion module. Each drive and control structure, namely each expansion module, does not need to be independently provided with a power supply structure part, a parameter configuration module and the like, and power supply, parameter configuration and the like are uniformly performed through the basic module, so that the cost of the multi-way valve amplifier is reduced, the mounting space of the multi-way valve amplifier is reduced, and the wiring harness is greatly simplified; and the comprehensive reliability of the electric control system is improved.

The application discloses a vehicle integrated lithium battery high-voltage power distribution system and a control method. The lithium battery high-voltage power distribution system comprises a high-voltage distribution box, a plurality of battery boxes and a connecting cable for connecting the high-voltage distribution box and the battery boxes and two groups of the battery boxes, which are stacked from top to bottom. The high-voltage distribution box is integrated with a control panel, a filter, a DCDC, a contactor, a fuse, a hard copper bar and a current sensor. The battery box is integrated with a BMS control box. The battery boxes are also connected with liquid cooling pipelines. The system effectively reduces the space occupied by the high-voltage power distribution system on the chassis by using the integrated design of the lithium battery high-voltage power supply and distribution system.
