Method and system for vehicle operation monitoring, parameter measurement and calculation and overload monitoring

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...

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
