Electric vehicle braking performance tester system

Abstract

The invention provides an electric vehicle braking performance tester system comprising a PLC controller electrically connected with a microcomputer. The PLC is electrically connected with a high-speed A / D collector; the high-speed A / D collector is electrically connected with three front brake handle sensors. The PLC is electrically connected with a pneumatic servo, the PLC is electrically connected with a front wheel servo, and the PLC is electrically connected with a rear wheel servo. The whole process of the computer is automatically controlled, and the computer automatically loads information according to a set program. The control system has a power failure recovery function; under the condition of an external power failure, automatic shutdown protection of the system and automatic saving of the last test result are performed; and automatic shutdown is performed when the required precision is exceeded. Automatic shutdown is carried out when the force value disappears, automatic shutdown is carried out when a sample is damaged, and a test curve can be tracked and displayed at any time, and amplification analysis, sample fracture overload and overcurrent self-protection can be carried out on any section of the curve.

Description

technical field [0001] The invention relates to the technical field of electric vehicle testing, in particular to an electric vehicle braking performance tester system. Background technique [0002] An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source on the basis of an ordinary bicycle, and is equipped with operating components such as a motor, a controller, a battery, a handlebar, and a display instrument system. [0003] Since electric bicycles are widely used in my country and have a large audience base, the detection of electric bicycles is particularly necessary to ensure the safety of their braking performance. However, the detection in the prior art still has the following problems: 1. The operation of mechanical installation samples Troublesome, and low reliability; 2. Software measurement capture and measurement data are not reliable. Contents of the invention [0004] In order to solve the above-mentioned...
