Problems solved by technology
When the braking performance of the vehicle is insufficient, it cannot reflect the value of the braking system pipeline pressure, pedal force, pedal opening, etc., let alone the relationship curve between them; in addition, if the pedal force sensor and pedal opening sensor are added , Negative pressure sensor, not only the cost is high, increase the cost of the vehicle, but also must redesign the pipeline structure of the bra

The invention discloses a data acquisition and application device of an automotive hydraulic braking system. The data acquisition and application device comprises a controller, a power supply, an angle sensor, a pedal force sensor and multiple pressure intensity sensors, wherein the angle sensor, the pedal force sensor and the pressure intensity sensors are respectively connected with the controller. The angle sensor is installed on a vehicle braking pedal rotation arm, the pedal force sensor is installed on the braking pedal surface, the pressure intensity sensors are respectively installed at a brake oil discharge outlet. The controller is further connected with a display device through CAN card. The data acquisition and application device can be carried in virtue of a low-pressure 24DC platform of a vehicle itself to acquire parameters of a braking system, parameter values are automatically output by utilizing the device, curve images are analyzed, and the soft braking cause can be accurately and rapidly locked. The braking performance problem can be automatically solved or the braking performance can be improved under the processable situation if no special device is not needed, for example, a driver manually exhausts air existing in the braking system, and too large gap and the like of a braking cylinder are adjusted by using a changing tool and other simple tools.
Description
technical field [0001] The invention belongs to the field of automobile braking, and in particular relates to a data acquisition application device of an automobile hydraulic braking system. Background technique [0002] At present, vehicles with hydraulic brakes, especially trucks with hydraulic brakes, often have insufficient braking performance, poor foot feel when braking, longer braking distances, and smaller braking decelerations. The performance is that the brakes are soft and the brake pedal travel is too long, which seriously affects the driving safety of the vehicle. In order to quickly and accurately lock the reason for the weak braking performance, it is necessary to check the value of each parameter of the brake system and analyze each parameter value at the same time. The relationship between the parameters to quickly and accurately lock the cause of soft brakes, but currently there is no one that can intuitively reflect the pedal force, vacuum booster negative...
