Problems solved by technology

[0017] Because there are hundreds of possibilities in the operating conditions of the vehicle, and the vehicle is in the switching state of low speed / high speed, light load / heavy load, acceleration / deceleration, uphill / downhill at any time, so the vehicle operating parameters (such as longitudinal speed, Longitudinal acceleration, vehicle mass, vehicle driving force, torque, power, current, etc.) may also change significantly in normal operating conditions; therefore, the existing B-type technical solutions can only be simply performed when the vehicle operating parameters exceed the safety limit Threshold (such as maximum speed limit, maximum acceleration limit value, maximum safe load capacity, maximum power, maximum torque, maximum current, etc.) to respond; before the vehicle operating parameters do not exceed the preset safety limit threshold, it is not easy to realize It is not easy to realize high-sensitivity early monitoring for the monitoring of the safety status of the vehicle operation; usually, it is only possible to wait passively and laggingly for the drive shaft of the vehicle to break, the drive gear to burst, or the tire to burst when there is no tire pressure monitoring system. Only after the occurrence of an incident that has caused a serious safety accident can the warning be given and the aftermath be dealt with

specific Embodiment

[0427] Second part content: concrete invention content of the present invention and specific embodiment are as follows:

[0428] One of the technical problems to be solved by the present invention is to provide a method to facilitate the monitoring of vehicle power transmission abnormalities (including those caused by the vehicle's rotating working power or transmission component failure) when the vehicle's operating parameters do not exceed the safety limit threshold. technical solutions;

[0429] The purpose of the present invention is achieved through the following technical solutions:

[0430] The present invention provides a monitoring method (#1) when the vehicle is controlled by a power plant, and the monitoring method includes the steps of:

[0431] A. Acquiring the joint calculation value of the measurement object of the vehicle, and judging whether the power transmission condition of the vehicle is abnormal according to the acquired joint calculation value and the r...

example 1

[0467] Example 1: If the longitudinal speed of the vehicle is used as the measurement object, assuming that the safety limit threshold value is 200KM / H, assuming that the vehicle is running at a longitudinal speed of 60KM / H, the actual value is usually set to 60KM / H, and the recognition of power transmission status is poor. The value is usually set between 10-20KM / H, the upper limit of power transmission status identification is usually set between 70-80KM / H, and the lower limit of power transmission status identification is usually set at 40-50KM / H between; then as long as the combined calculation value of the longitudinal running speed of the vehicle is greater than the upper limit value of the power transmission status identification or less than the lower limit value of the power transmission status identification, the judgment result of the power transmission status will be abnormal, so that monitoring and protection can be realized; and this When the measured object is fa...

example 2

[0468] Example 2: If the vehicle’s carrying mass is used as the measurement object, assuming that the safety limit threshold is 7 people / 560KG, and when the vehicle is actually loaded with 4 people / 320KG, the actual value is usually set to 320KG, and the power transmission status identification The difference is usually set between 80-160KG, the upper limit of power transmission status identification is usually set to 480KG, and the lower limit of power transmission status identification is usually set to 160KG; If the power transmission status identification upper limit value or is less than the power transmission status identification lower limit value, the judgment result of the power transmission status will be abnormal, so that monitoring and protection can be realized; and at this time, the measured object is far from the safety limit threshold (560KG);

[0469] In the existing technical scheme, only when the combined calculation value is higher than the maximum value (su...

Abstract

The invention discloses a method and system for vehicle operation monitoring, parameter measurement and calculation and overload monitoring. A monitoring method used when a vehicle is controlled by a power device to run is characterized by comprising the following steps of obtaining the joint operation values of a measurement and calculation object of the vehicle; judging whether the power transmitting condition of the vehicle is abnormal or not according to the obtained joint operation values and reference values of the measurement and calculation object, wherein the measurement and calculation object is any parameter selected from the vehicle mass of the vehicle, a source dynamic parameter and a system running parameter, and the joint operation values are obtained through calculation by using vehicle motion balance as a principle; and if the judging result is that the power transmitting condition of the vehicle is abnormal, starting a set power transmitting exception handling mechanism.

Description

technical field [0001] The invention relates to the technical field of vehicles, and more specifically, relates to a method and system for vehicle operation monitoring, parameter calculation and overload monitoring. Background technique [0002] Vehicles running on land are currently one of the most important and basic means of transportation in the world; because the safety of vehicles is closely related to the safety of drivers and passengers, improving the safety monitoring performance of vehicles is always for vehicles the core focus of the technology; [0003] In terms of structure, a vehicle usually has a power system that generates power and a mechanical transmission system that transmits power; the power system usually has an energy supply device, a power control device, and a power device; [0004] According to the type of power system, vehicles include fuel power, electric power, hybrid power system, etc.; [0005] Existing fuel-powered vehicles, including gasoli...
