Abstract

The invention provides an acceleration and brake pedal signal control device and method for a test vehicle, and the device comprises an upper computer, a pedal control unit, an acceleration pedal control mechanism, and a brake pedal control mechanism. The CAN bus signal transceiving end of the upper computer is connected with the CAN bus signal transceiving end of the pedal control unit, the acceleration pedal control signal output end of the pedal control unit is connected with the control signal input end of the acceleration pedal control mechanism, and the brake pedal control signal outputend of the pedal control unit is connected with the control signal input end of the brake pedal control mechanism. The power input end of the pedal control unit is connected with a storage battery power output end. The problem that the pedal control precision is not easy to control in the dynamic test of the test vehicle is solved, and the test efficiency of related tests is improved.

Description

technical field [0001] The invention relates to test vehicle driving test equipment, in particular to an accelerator pedal and brake pedal signal control device and method for a test vehicle. Background technique [0002] Automobile testing, including benchmarking vehicle testing and vehicle testing under development, is an essential link in the automotive development process. The accuracy of test data and the efficiency of the testing process are very important for the development of new models. For example, in the analysis of benchmarking models, in order to obtain the relevant performance of the benchmarking models, a complex test matrix is ​​generally used to obtain the desired information through experimental testing and analysis of test data, such as driving control strategy testing and braking control strategy testing , single-pedal characteristic test and braking distance test, etc. [0003] During the vehicle dynamic test process, the vehicle is usually controlled ...
