Inertia in mechanism is equal；The quality of counterweight 5 is determined, its power of effect in systems is made acceleration caused by system and institute's mould
Acceleration caused by halting mechanism output end under the vehicle car slipping operating mode of plan, by adjusting the mass of counterweight 5, can simulate vehicle
The operating mode of parking on various slope roads；Ensure that the clamping torque of clutch 11 is more than opplied moment caused by counterweight 5.On-test
Before, the gear level of test specimen 2 is in non-P gear states, and clutch 11 is in bonding state.During on-test, actuator is manipulated
16 make the gear level of test specimen 2 enter P gear states, and then operating clutch controller 10 makes clutch 11 be changed into separating shape
State, system can produce motion in the presence of the gravity of counterweight 5, until the halting mechanism of test specimen 2 plays a role and actually entered
Parked state, system motion stop, and complete once to simulate slope road parking experiment.Can be by turning on test specimen 2

Refering to Fig. 2, when simulating dynamic parking experiment, the drag-line 6, gate-type beam 7 and clutch-pedal support 12 in the device are equal
The device is not connected into；Calculating process and the experiment of simulation slope road parking function and releasing parking function experiment phase when stand is built
Together.Before on-test, the gear level of test specimen 2 is in non-P gear states, and clutch 11 is in bonding state.During on-test,
The adjustment of rotational speed of motor 15 is to more slightly higher than predetermined test speed, and now controlled clutch controller 10 makes clutch 11 be changed into point
From state, treat that the rotating speed of flywheel 8 is down to predetermined test speed, manipulating actuator 16 makes the gear level of test specimen 2 enter P
Gear, test specimen 2 is waited completely into parked state, system, which rotates, to be stopped, and completes once to simulate dynamic parking experiment.It can lead to
The rotating speed of power transmission shaft A3 when speed probe measures test specimen 2 completely into parked state is crossed, is entered so as to calculate vehicle
Speed during parked state, judges whether the performance of halting mechanism reaches design requirement.
