Abstract

The invention relates to a new energy vehicle vehicle control strategy and a network test platform, including: a digital quantity and analog quantity input module, a test host and a CAN bus analyzer; the digital quantity and analog quantity input module connects the vehicle The demand signal is unidirectionally transmitted to the vehicle controller under test; the test host exchanges information with the vehicle controller under test and the CAN bus analyzer respectively through hard wires; the CAN bus analyzer, the vehicle controller under test, Instruments, motor controllers, battery management systems and chargers exchange data through the CAN network; the CAN bus analyzer will receive the CAN Signals are converted to hardwired signals and transmitted via hardwires to the test host. The beneficial effect of the present invention is that the whole vehicle control strategy and the network function test can be carried out simultaneously on the test platform, which improves the accuracy of the test and reduces the test period.

Description

technical field [0001] The invention relates to a new energy vehicle vehicle control strategy and a network test platform. Background technique [0002] The vehicle control strategy is the core design of the new energy vehicle vehicle control system, which plays a key role in supervising and adjusting the various executive agencies, realizing and ensuring the driving safety of new energy vehicles. In order to verify the correctness and effectiveness of the vehicle control strategy, a hardware-in-the-loop simulation system is usually established to simulate and verify the vehicle controller strategy. When establishing a hardware-in-the-loop simulation system, it is necessary to establish a series of sub- model, and there will be a certain deviation between the sub-model and the actual parts, resulting in a certain difference between the simulation results and the actual vehicle results. [0003] The vehicle network function test mainly refers to the test of the vehicle netwo...
