In another embodiment, the ignition and shift actuator includes an engine control unit/motor control unit and a transmission control unit; the engine control unit/motor control unit is used for carrying out ignition operation on the test vehicle under the action of the controller 300; the transmission control unit is used for performing gear shifting operation on the test vehicle under the action of the controller 300. Therefore, in the embodiment, no additional robot is required to be arranged, and the engine/motor of the test vehicle is operated by directly performing ignition operation on the test vehicle through the engine control unit/motor control unit according to the control signal output by the controller 300; and performs a gear shifting operation on the test vehicle according to the control signal output from the controller 300 through the transmission control unit. Because the ignition operation in the embodiment is automatically executed through the engine control unit/motor control unit, and the gear shifting operation is automatically executed through the gearbox control unit, in a vehicle hub test, the gearbox gear and the engine/motor operation condition can be accurately controlled, and the problem that the consistency and the accuracy of a test result are influenced due to the skill of a test driver, an operation method, personnel difference and the like is effectively avoided.
In summary, compared with the prior art, the automatic driving control system for the vehicle hub test provided by the invention has the following advantages:
(1) the automatic driving control system comprises a pedal actuating mechanism, an ignition and gear shifting actuating mechanism and a controller, wherein the pedal actuating mechanism is used for carrying out pedal control operation on a test vehicle under the control of the controller, and the ignition and gear shifting actuating mechanism is used for carrying out ignition and gear shifting control operation on the test vehicle under the control of the controller. Therefore, the automatic driving control system for the vehicle hub rotation test provided by the invention can automatically perform various operations such as ignition, gear shifting, pedal control and the like of the vehicle when the vehicle performs the hub rotation test, can effectively avoid the problem that the speed of the whole vehicle, the gear of a gearbox and the operation condition of an engine/motor are difficult to accurately control in the vehicle hub rotation test, and can also effectively avoid the problem that the consistency and the accuracy of the test result are influenced by the skill, the operation method, the personnel difference and the like of a test driver.
(2) The pedal actuating mechanism is driven by the servo motor, so that the pedal stroke of a test vehicle in a vehicle hub test can be accurately controlled, and the pedal stroke position can be accurately calibrated, so that the actuating stroke is adjustable and the response speed is higher for different vehicles.
(3) The ignition and gear shifting actuating mechanism adopts a six-freedom-degree robot to perform ignition and gear shifting operation, namely the robot can realize the movement in 6 directions in the up-down, left-right and front-back spaces, so the control action speed is quicker, and the position control precision is higher.
