Description

Technical Field

[0001] This invention relates to the field of vehicle testing technology, and in particular to a speed control auxiliary device for vehicle testing. Background Technology

[0002] With increasing societal emphasis on environmental protection, cost reduction, and production efficiency, the evaluation of vehicle control systems has become particularly crucial in the automotive industry. This involves collecting performance test data of the vehicle control system under different engine operating conditions.

[0003] In existing technologies, to collect timely, real-time, and accurate test data of the vehicle control system under different operating conditions, the only method is to use a vehicle environmental test chamber and manually operate the accelerator pedal to determine whether parameters such as engine speed, temperature, water flow, and pressure corresponding to constant engine speeds under different operating conditions meet the evaluation criteria. However, this method can lead to numbness in the driver's feet over time, resulting in unstable engine speeds and inconsistent data with the test standards, thus affecting the overall vehicle performance test results and evaluation criteria. For example, patent CN219996521U discloses an automotive operating condition testing device, which includes a base plate with two L-shaped supports. One L-shaped support is fixedly equipped with an accelerator testing device, and the other L-shaped support is fixedly equipped with a brake testing device; however, the two supports are separate and cannot be linked for control.

[0009] The pedal housing and the bracket cantilever are an integral structure.

[0010] The pedal sleeve is equipped with locking and positioning fastening bolts.

[0011] The bottom of the pedal cover has an opening along the longitudinal direction, and the bottom of the pedal cover has a pair of bottom folds corresponding to the opening.

[0012] The speed-regulating push structure is an electric push rod with a self-locking function.

[0013] The speed-regulating drive structure is a speed-regulating screw, with an adjustment threaded hole on the end of the bracket cantilever. The speed-regulating screw mates with the adjustment threaded hole, and an adjustment handwheel is provided at the upper end of the speed-regulating screw.

[0014] It also includes a connected engine speed sensor and controller, which is connected to an electric push rod.

[0015] Compared with the prior art, the present invention has the following advantages: The speed control auxiliary device used for vehicle testing has a reasonable structural design, is firmly installed and positioned, is simple to operate, and has accurate positioning without the need for other supports for positioning.
