Description

[Detailed description of the invention] [Industrial application field] This invention is a test vehicle driving robot, in particular, a test vehicle that controls acceleration and deceleration on a chassis dynamometer and performs tests according to a desired driving pattern. Concerning improvements to robots for driving test vehicles.

[Background Art] As a driving performance test for automobiles, a pattern driving test according to, for example, 10 mode, 11 mode, LA#4 mode, etc. is well known. A meter is used.

Conventionally, such pattern driving tests have been conducted by having a driver accelerate and decelerate a test vehicle placed on a chassis dynamometer according to a predetermined driving pattern.

The inventor has developed a pattern running test robot that can automatically perform such pattern running tests on a chassis dynamometer.
The details will be explained below, taking as an example the case where a pattern driving test is performed on an automatic vehicle.

Robot for Pattern Driving Test FIG. 8 shows a system of such a robot for pattern driving test. The test vehicle 12 has a drive wheel 14 locked and a roller 1 mounted on the drive wheel 16.
The same load as in the actual running condition is applied through the motor 8.

In order to accelerate and decelerate the thus installed test vehicle 12 using the chassis dynamometer 10, an accelerator operating arm 20 and a brake operating arm 22 are attached to the accelerator and brake in the vehicle interior, respectively, and the control device 24 drives the accelerator actuator 26 and brake actuator 28, the corresponding operating arms 20 and 22 are driven via wires 30 and 32, and the amount of depression of the accelerator and brake keys is controlled.

In this case, as shown in Fig. 9, a straight plate is used for the brake operating arm 22, and the thickness of the plate is large enough to cope with the reaction force (30 Kamax) when the brake pedal is operated. Ta.

[Problems to be solved by the invention] However, such a pedal operation jig 34
When trying to use the brake control arm in many vehicle models, the brake operating arm 22 and the brake pedal 40 may interfere with each other, and in order to avoid such a situation, a large number of man-hours are required to install the brake control arm to the vehicle. Furthermore, since the brake operating arm 20 itself is heavy, there have been problems such as the inability to accurately control the pedaling force.

Furthermore, if the fulcrum of the brake key operating arm 20 is not aligned with the center axis of the lifting prevention mechanism 38 provided between the pedal operating jig 34 and the steering wheel 36, when a strong brake reaction force acts on the fulcrum, There was a problem in that the pedal operating jig 34 floated or moved in the left-right direction due to the force couple at that time.

Purpose of the invention This invention was made to solve these problems, and the purpose is to provide a robot for driving a test vehicle that can reliably control the depression of the brake pedal and is highly versatile.

[Means and effects for solving the problem] The robot for driving a test vehicle according to this invention is provided with a lifting prevention mechanism between the pedal operating jig and the steering wheel, and also has a brake operating arm positioned at the position of the brake pedal. Accordingly, it is formed so that its position can be freely adjusted in a direction perpendicular to the rotating operation surface around its pivot position, and its pivot position is aligned with the center axis of the lifting prevention mechanism.

The lifting prevention mechanism prevents the pedal operating jig from lifting from the vehicle body floor due to the reaction force when the brake operating arm depresses the brake pedal, and the required pressing force is accurately transmitted to the pedal.

In addition, the brake operating arm is formed so that its position can be adjusted in the direction perpendicular to the rotational operating surface around the pivot position, so even if the vehicle model changes, it can be easily adjusted to suit different vehicle models. It has the advantage of being highly versatile.

Furthermore, since the fulcrum of the brake operating arm is aligned with the central axis of the lifting prevention mechanism, even when a strong brake reaction force is applied to the fulcrum, the pedal operating jig will not move due to the force couple. There is no fear of it happening.

[Embodiments] Preferred embodiments of the present invention will be described below based on the drawings.

Due to the pulling force of the actuator wires 64 and 66, the accelerator pedal 60 and brake pedal 62 are depressed by the required amount, and acceleration/deceleration driving is performed according to the desired test mode.

Here, the characteristic feature of the present invention is that a lifting prevention mechanism is provided between the pedal operating jig and the steering wheel, and the brake operating arm rotatably attached to the pedal operating jig is connected to the brake pedal. The mechanism is formed such that its position can be freely adjusted in a direction perpendicular to the rotating operation surface around the pivot position according to the position of the mechanism, and the pivot position is made to coincide with the central axis of the lifting prevention mechanism.

That is, an arm shaft 46 supporting an accelerator operating arm 48 and a brake operating arm 50;
A lifting prevention mechanism 68 is provided between the steering wheel 45 and the arm 70, and the lifting prevention mechanism 68 extends from one end of the rod 70, as shown in FIG. A leg 72- serves to press the shaft 46.
