Abstract
The utility model discloses a fast signal adapter of wheel. It includes ABS system, sampling amplification circuit, an amplifier circuit, the 2nd amplifier circuit, left front round of fast sensor of wheel and the fast sensor of off -front wheel wheel, and the ABS system links to each other with sampling amplification circuit, an amplifier circuit, the 2nd amplifier circuit and the fast sensor of off -front wheel wheel respectively, and an amplifier circuit, the 2nd amplifier circuit all link to each other with the sampling amplification circuit, and the sampling amplification circuit links to each other with the fast sensor of left front round of wheel. The utility model discloses when guaranteeing that the vehicle is tested on 2WD chassis dynamometer, the ABS function can normal operating.
Description
Technical field
The utility model relates to automobile technical field, particularly relates to wheel speed signal adapter.
Background technology
Current automobile is generally equipped with ABS (Anti-lock Braking System) module (referred to as ABS), and ABS gathers wheel speed signal for module by 4 wheel speed sensors (referred to as WSS) and provides operational data, when vehicle is tested on 2WD chassis dynamometer, because trailing wheel maintains static, ABS module is fed back to (or for vehicle body stabilizing control system without trailing wheel vehicle speed signal, be called for short DSC, usual integrated ABS function), now ABS can be mistaken for WSS fault, may cause two consequences thus.One, ABS system thinks there is hardware fault, cannot run according to normal condition; Two, other related system, as power train control module (referred to as PCM) thinks that ABS is in malfunction, therefore can allow the function relevant with ABS enter protection operational mode.Above two consequences all can cause on 2WD chassis dynamometer, normally cannot simulating road driving state.Traditional normal vehicle wheel speed signal input circuit schematic diagram as shown in Figure 1.
Therefore, those skilled in the art is devoted to develop a kind of wheel speed signal adapter.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of wheel speed signal adapter, and ensure that vehicle when testing on 2WD chassis dynamometer, ABS function can normally be run.
For achieving the above object, the utility model provides a kind of wheel speed signal adapter, comprise ABS system, amplifier circuit, the first amplifying circuit, the second amplifying circuit, the near front wheel wheel speed sensors and off-front wheel wheel speed sensors, ABS system is connected with off-front wheel wheel speed sensors with amplifier circuit, the first amplifying circuit, the second amplifying circuit respectively, first amplifying circuit, the second amplifying circuit are all connected with amplifier circuit, and amplifier circuit is connected with the near front wheel wheel speed sensors.
As preferably, described ABS system can be replaced DSC module.
The beneficial effects of the utility model:
Front-wheel vehicle speed signal can be copied the rear wheel speed signal adapter inputing to DSC module as trailing wheel wheel speed signal by the utility model, makes DSC module think that wheel speed sensors is working properly.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is the structural representation of background technology of the present utility model;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 2, a specific embodiment of the present utility model, a kind of wheel speed signal adapter, comprise ABS system 1, amplifier circuit 2, first amplifying circuit 3, second amplifying circuit 4, the near front wheel wheel speed sensors 5 and off-front wheel wheel speed sensors 6, ABS system 1 is connected with off-front wheel wheel speed sensors 6 with amplifier circuit 2, first amplifying circuit 3, second amplifying circuit 4 respectively, first amplifying circuit 3, second amplifying circuit 4 is all connected with amplifier circuit 2, and amplifier circuit 2 is connected with the near front wheel wheel speed sensors 5.
It should be noted that described ABS system 1 can be replaced DSC module.
The installation method of the present embodiment is:
1, check vehicles, confirm system failure before changing the outfit;
2, storage battery negative pole is disconnected;
3, harness connector plug is pulled down from DSC module;
4, the two ends of patchcord are connected respectively to wire harness and DSC module;
5, the power line of patchcord is connected to storage battery positive pole, and fixes power line.
6, the negative pole of storage battery is connected with vehicle body;
7, signal adapter is fixed on vehicle body, and is connected to patchcord;
8, storage battery negative pole is connected, full car power supply is connected, waiting system self-inspection terminates (about 5 second), ato unit by twice vehicle ignition switch, on somascope dial plate, anti-sideslip alarm lamp and ABS alarm lamp whether Chang Liang, does not work and then illustrates that DSC system works is normal.
9, after trial test terminates engine misses, the power line on positive pole is taken off, before the energising of formal test vehicle, then line of connecting with the mains.
When the adapter of this embodiment can make vehicle test on 2WD chassis dynamometer, ABS (or DSC) can not think WSS fault.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection range of claims.
