Problems solved by technology

[0003] In the existing technology, the electronic stability control system of commercial vehicles is often tested. However, since there is no specific evaluation system for ESC function performance in the field of commercial vehicles, it is impossible to conduct a comprehensive and systematic evaluation of the ESC system, resulting in defects in the system that cannot be tested. Discovered in time, making efficient optimization of ESC systems difficult

Abstract

The invention discloses a test optimization method, device and system for an automotive electronic stabilization system. The test optimization device comprises a data acquisition unit, a performance evaluation unit and an optimization management unit. The test optimization system comprises a test optimization module, a data storage module and a user interaction module. A fixed steering wheel acceleration test data set, a fixed radius acceleration test data set, a J steering test data set, a single lane change test data set and a double shift line test data set of a to-be-tested automobile are acquired, and the anti-rollover performance and the direction control performance of the to-be-tested automobile are comprehensively evaluated according to the multiple test data sets. Therefore, the test comprehensiveness of the automobile electronic stability system is improved.

Description

technical field [0001] The invention relates to the field of test optimization of an automobile electronic stability system, and relates to a test optimization method, device and system of an automobile electronic stability system. Background technique [0002] The automotive electronic stability control system is a new type of active safety system for the vehicle. It is a further expansion of the functions of the automotive anti-lock braking system (ABS) and the traction control system (TCS). On this basis, it increases the yaw when the vehicle is turning. The speed sensor, lateral acceleration sensor and steering wheel angle sensor are used to control the power output of the engine and the braking force of each axle through the ECU to ensure the lateral stability of the vehicle. [0003] In the prior art, the electronic stability control system of commercial vehicles is often tested. However, since there is no specific evaluation system for the performance of ESC functions...
