Electrical and control integrated system of electric truck chassis and corresponding control method

Abstract

The invention relates to an electric and control integration system and method of an electric truck chassis. The system comprises vehicle-mounted low-voltage power utilization equipment, vehicle-mounted high-voltage power utilization equipment, a high-voltage / low-voltage power supply wire harness, a communication control wire harness, a pipeline system, a lower-voltage power distribution box, a power supply distribution box and a vehicle controller; the system is provided with an assembling bracket assembly arranged below a cab; the assembling bracket assembly is used for packaging all electric appliance parts and an auxiliary system; the lower-voltage power distribution box is connected with the vehicle-mounted low-voltage power utilization equipment through the low-voltage power supply wire harness; the power supply distribution box is connected with the vehicle-mounted high-voltage power utilization equipment through the high-voltage power supply wire harness; two ends of the communication control wire harness are connected with parts needing to be subjected to communication control, and the communication control comprises connection between the vehicle controller and the vehicle-mounted low-voltage power utilization equipment and between the vehicle controller and the vehicle-mounted high-voltage power utilization equipment respectively. When a car adopts the system, the space of the chassis can be saved, and the parts are convenient to modify, repair and maintain; an assembling process of a complete vehicle manufacturer is simplified in a production process; the production is convenient and the technology and safety risks are reduced.

Description

technical field [0001] The invention relates to the field of electric trucks, in particular to the field of integrated assembly of electric truck chassis, and specifically refers to an electrical and control integrated system and corresponding control method of the electric truck chassis. Background technique [0002] The rational layout of electrical components and auxiliary systems of electric vehicles on the vehicle has always been the core design content of the vehicle design, and there are many technical disputes, which is particularly strict and important for passenger vehicles. On the slightly spacious electric truck chassis, the rational layout of electrical components and their auxiliary systems has not become easier due to the increase in space, mainly due to the increase in the volume of components and wiring harnesses. On the electric truck chassis, there are basically no debates about the layout of the power system and the layout of the battery, because the use ...

AI Technical Summary

Problems solved by technology

The problems brought about by this method are: the installation stations on the production line consume a lot of man-hours, and the efficiency is low; the final debugging and verification before going offline takes a lot of time and affects the flow of the production line, and it needs to be separated from the production line. The line is tested separately and then offline; the technical requirements for on-site software and hardware testing are high, and professional testing workers and equipment are required; troubleshooting is difficult, and it is difficult to find the fault point in a short time without sufficient professional knowledge and experience; when assembling and debugging , there are many safety precautions in the high-voltage system, and professional electricians are required to carry out electrical connection and wiring harness processing, which is inconsistent with the relatively fast requirements of traditional production rhythms; it affects the modification needs of end users, and brings new problems to the modification, maintenance and maintenance of later parts. greater difficulty
