Embodiment Construction

[0031] The sports vehicle emission parameter data acquisition system of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0032] The acquisition of the temperature of the catalytic converter during the vehicle driving cycle is the basic condition for the realization of the bench durability method. Due to the different road conditions and driver habits, the consistency and stability of the catalytic converter temperature data will be affected to varying degrees. The sports vehicle emission parameter data collection system of the present invention forms a unified, standardized and portable temperature collection system, and the sports vehicle vehicle-mounted data collection system solves the problem of means for obtaining real test data. It ensures the driver's standard operation and the working state of the tested vehicle, and accurately records the temperature in the exhaust after-treatment device on th...

Abstract

A data acquisition system for emission parameters of a sports vehicle, comprising a CAN card connected to a host computer, the connector of the CAN card connected to a CAN bus, respectively provided with a vehicle condition tracking unit, a driver A monitoring unit and a temperature testing unit for an exhaust aftertreatment device. A CAN card is a CAN card with two CAN connectors. The vehicle condition tracking unit has a four-channel data acquisition module connected with the CAN bus, and a GPS vehicle speedometer connected with the four-channel data acquisition module. The driver monitoring unit has a driver monitoring display connected to the CAN bus, a four-channel data acquisition module, and the four-channel data acquisition module is respectively connected to a pedal force sensor and a pedal displacement sensor. The invention can not only monitor the driving habit of the driver, but also monitor the state of the vehicle, calculate the acceleration and deceleration of the vehicle running, and provide an operable means for the vehicle to carry out tests strictly in accordance with the operating conditions stipulated by laws and regulations.

Description

technical field [0001] The invention relates to an automobile emission testing system. In particular, it relates to a vehicle emission parameter data acquisition system for light-duty gasoline vehicles under actual driving conditions or operating conditions stipulated by regulations. Background technique [0002] Bench durability test of light vehicle exhaust aftertreatment device is an aging test method that simulates the road durability process with a bench, and reduces the durability time by increasing the temperature of the catalyst. The prerequisite is the accurate collection of the catalyst temperature in the road durability test. Therefore, a vehicle emission parameter data acquisition system is needed. [0003] The existing catalytic converter temperature data acquisition technology only collects the catalytic converter temperature on the engine bench, and the aging time of the catalytic converter is also the empirical aging time, and there is no systematic and stan...
