What does VCU mean in new energy vehicles?
1 Answers
VCU in new energy vehicles is the core electronic control unit that implements vehicle control decisions. It is generally only equipped in new energy vehicles, while traditional fuel vehicles do not require this device. New energy vehicles are those that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices). Extended information: 1. The working principle of VCU in new energy vehicles: The VCU collects signals from the accelerator pedal, gear, brake pedal, etc., to determine the driver's intentions. By monitoring vehicle status information (such as speed, temperature, etc.), the VCU processes and judges the data, then sends control commands for the vehicle's operating status to the power system and the power battery system, while also controlling the working mode of the onboard auxiliary power system. The VCU has functions for diagnosing, protecting against, and storing faults in the entire vehicle system. 2. The structural composition of VCU: It includes a housing, hardware circuits, underlying software, and application layer software. The hardware circuits, underlying software, and application layer software are the key core technologies of the VCU.
