Vehicle operation monitoring, parameter measuring and calculating, overload monitoring method and system

Abstract

The invention discloses a vehicle operation monitoring, parameter measuring and calculating, overload monitoring method and system. The vehicle operation monitoring, parameter measuring and calculating, overload monitoring method is a monitoring method when a vehicle is controlled to operate by using a power device; and the power device is a motor. The vehicle operation monitoring, parameter measuring and calculating, overload monitoring method is characterized by comprising the following steps of obtaining a combined calculation value of measuring and calculating objects of the vehicle; judging whether the power transmission status of the vehicle is abnormal or not according to the obtained combined calculation value and a reference value of the measuring and calculating objects, wherein the measuring and calculating object is any one or more of vehicle mass, a source power parameter and a system operation parameter of the vehicle; and the combined calculation value is figured out with vehicle motion balance as principle; and the source power parameters comprise any one or both of a motor driving parameter and rear-end electric power parameter; and if the judging result is that the power transmission status of the vehicle is abnormal, starting a set power transmission abnormality processing mechanism.

Description

technical field [0001] The present invention relates to the technical field of vehicles, more specifically, to a method and system for vehicle operation monitoring, parameter calculation, overload monitoring and 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] Divided from the type of power system, vehicles include fuel power, electric power, hybrid power system, etc.; because fuel power vehicles are likely to cause se...

Problems solved by technology

[0014] 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 undergo substantial changes 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
