Problems solved by technology

[0004] Since the K&C characteristic simulation test of the vehicle needs to apply braking force to the vehicle for a long time, after a long time test, the test driver may not be able to continue the test due to fatigue. Personnel are also prone to deviations in the stepping stroke of the brake pedal due to lack of experience or operational errors, resulting in long test cycles and low accuracy

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] In the related art, when performing the K&C characteristic simulation test of the vehicle, the test driver usually continuously depresses and releases the brake pedal inside the vehicle.

[0033] Since the K&C characteristic simulation test of the vehicle needs to apply braking force to the vehicle for a long time, after a long time test, the test driver may not be able to continue the test due to fatigue. Personnel are also prone to deviations in the stepping stroke of the brake pedal due to inexperience or operational errors, resulting in long test periods and low accuracy.

Abstract

The invention provides a brake pedal test control device and control method, and belongs to the technical field of automobile test equipment. The brake pedal test control device comprises a driving assembly and a control assembly. The driving assembly comprises a telescopic rod and a fixing support, the fixing support is connected with one end of the telescopic rod, the fixing support is used for being fixedly connected with a seat of a vehicle, and the other end of the telescopic rod is used for being fixedly connected with a brake pedal of the vehicle. The control assembly comprises an electronic control unit and a brake pipeline pressure sensor, the brake pipeline pressure sensor is used for being installed on a brake pipeline of the vehicle to detect oil pressure in the brake pipeline, the electronic control unit is electrically connected with the brake pipeline pressure sensor and the telescopic rod, the electronic control unit is configured to drive the telescopic rod to stretch out and draw back according to the oil pressure. According to different test working condition requirements, the stroke of the brake pedal can be continuously and accurately controlled, the test period of a K&C characteristic simulation test of the vehicle is shortened, and the test accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of automobile test equipment, in particular to a brake pedal test control device and control method. Background technique [0002] The K&C characteristics of the vehicle, namely kinematics and elastokinematics. Among them, the kinematics characteristic mainly describes the change rule of the wheel alignment parameters caused by the suspension movement, which is related to the geometric parameters of the vehicle suspension guiding mechanism. When the car is moving forward, when it encounters uneven roads, the wheels will jump in the same direction, or the wheel will jump in the opposite direction when the vehicle turns. Under these conditions, the characteristics of the wheels when they jump up and down are kinematic properties. The elasto-kinematics characteristic mainly describes the change law of the wheel alignment parameters caused by the force and moment between the tire and the road surface, and is m...
