Method for obtaining car loading capacity without additional mounting of sensor

Abstract

The invention discloses a method for obtaining the car loading capacity without additional mounting of a sensor. Devices used in the method comprise a car-mounted terminal, a central server and a carCAN bus. The car CAN bus is connected with the car-mounted terminal through a data cable to transmit three CAN parameters of the engine torque, the gearbox speed ratio and the car speed which are generated in real time to the car-mounted terminal. The car-mounted terminal is connected with the central server through a wireless network to real-timely report the collected CAN parameters to the central server. According to the method, the car loading capacity value can be calculated through a reversal estimation model of a car travelling equation by combining with information such as the car tireradius and the rear axle speed ratio according to the CAN parameters collected by the CAN bus, the loading capacity information can be collected without additional mounting of any external device, and the method has important development value when being applied to the technical field of fleet management.

Description

technical field [0001] The invention relates to a load acquisition method, in particular to a vehicle load acquisition method without additional sensors. Background technique [0002] The load problem has always been an important problem for fleet managers. Since the difference in load capacity will involve the settlement of operating costs, the formulation of standards, and the planning of operating routes and separation areas (or loading and unloading points), how to obtain vehicle load information conveniently and effectively is the most concerned by fleet managers. one of the problems. At present, there is no technical solution for automatic load monitoring in the market, and it is necessary to purchase external equipment to realize the collection of load information, such as adding external sensors to each vehicle, or using weighing equipment such as weighbridges, etc. However, both of these solutions involve increases in management costs such as hardware costs, insta...

At present, there is no technical implementation solution for automatic load monitoring in the market, and it is necessary to purchase external equipment to realize the collection of load information, such as adding external sensors to each vehicle, or using weighing equipment such as weighbridges, etc.

However, both of these solutions involve an increase in management costs such as hardware costs, installation costs, and maintenance costs.
