Detection device of inductive sensor, automobile and automobile body height detection method

Abstract

The invention discloses a detection device of an inductive sensor, an automobile and an automobile body height detection method. The device comprises a power supply which charges an inductive sensor according to set charging time; a comparison module which is used for comparing the charging voltage of the inductive sensor with a set reference voltage and outputting a logic signal; an acquisition module which is used for acquiring the time from the start of charging the inductive sensor by the power supply to the output of the logic signal by the comparison module as the effective charging time; and a control unit which is used for determining whether a fault occurs or not according to the effective charging time and the set charging time, issuing a reminding message if the inductive sensoror a sampling unit fails, and determining a detection value of the inductive sensor according to the effective charging time if the inductive sensor does not fail. According to the scheme, only whenit is determined that the inductive height sensor has no fault, the collected automobile body height is used for controlling operation of the automobile, and the reliability of automobile operation can be improved.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a detection device of an inductive sensor, a vehicle and a vehicle body height detection method thereof, in particular to an inductive height sensor acquisition and fault diagnosis device, a vehicle and a vehicle body height detection method thereof. Background technique [0002] There are many sensors and actuators in the electrical system of a car. For example, in the chassis suspension of a car, a height sensor is used to accurately measure the distance between the car body and the ground in real time, so the acquisition accuracy and reliability of the height sensor are particularly high. important. If a height sensor in the chassis suspension system breaks down, the vehicle body height collected by it will be inaccurate, which will affect the reliability of the entire chassis suspension system. [0003] The above content is only used to assist in understanding th...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a detection device for an inductive sensor, a vehicle and a vehicle body height detection method thereof, so as to solve the problem that the vehicle body height collected by the inductive height sensor itself is not accurate. Controlling the operation of the car will affect the reliability of the car's operation. Only when it is determined that the inductive height sensor itself is not faulty is used to control the operation of the car by using the height collected by the inductive height sensor, which can improve the reliability of the car's operation.
