Abstract: The overall vehicle configuration and design are described,
which include electrical and control system design and mechanism system
design. Electrical and control system design include low-voltage
electrical system design, high-voltage electrical system design, overall
vehicle control and energy management system design. This vehicle
chooses high performance horizon lead-acid battery and the battery box
is designed specially. Steering is electrohydraulic power steering,
which not only minimizes the energy consumption but also turns easily.
Electrical system parameter match is calculated, which includes
parameter selection of motor and battery. Handleability and stability,
passibility are also calculated. In the end the test resuit is provided,
which indicates that the vehicle performance targets all attain the
request of Ministry of Science and Technology and the vehicle
configuration design is reasonable and electrical system parameter match
result accord with the test result.
