Embodiment Construction

[0017] The present invention will be further described below.

[0018] This GPS-based road and vehicle use information collection method comprises the following steps

[0019] The GPS device installed on the vehicle measures the slope information i. The GPS device obtains the current engine torque value T and the current engine speed from the CAN bus information sent by the engine ECU. The GPS device obtains the current engine output shaft speed from the CAN bus information sent by the engine ECU, and obtains the current gear transmission ratio ig by comparing the current engine speed with the current engine output shaft speed. The GPS device obtains the vehicle speed value U from the CAN bus information sent by the ABS , and calculate the current vehicle acceleration value du / dt according to multiple vehicle speed values. The GPS device according to the formula T×ig×i ×ηt / r=G×f+Cd×A / 21.15×U × U +G×i-δ×m×du / dt to calculate the current vehicle weight G, where i Spee...

Abstract

The invention relates to a GPS-based road and vehicle use information acquisition method. GPS equipment is used for measuring the slope information I, the current engine torque value T and the current engine rotating speed, and is used for acquiring the current gear transmission speed ratio ig, the vehicle speed value U<alpha> and the acceleration magnitude du / dt; the current vehicle weight G is calculated and the calculated vehicle weight G is sent to a remote enterprise monitoring platform; designers can carry out strength improvement design according to the vehicle required by a client in the environment for meeting the normal reliable use of the vehicle in the environment; the GPS equipment is used for acquiring the countershaft rotating speed omega1, the countershaft rotating speed omega2 during braking ending and the air pressure value P0 of the whole vehicle; the friction coefficient f of a transmission brake is calculated, the GPS equipment sends the calculated friction coefficient f to the remote enterprise monitoring platform, and therefore, the strength of the transmission brake is optimized by technicians, and the using reliability of the transmission brake under warranty is met.

Description

technical field [0001] The invention relates to the technical field of information collection methods, in particular to a GPS-based road and vehicle use information collection method. Background technique [0002] For heavy-duty commercial vehicles, the requirements for each major assembly vary greatly under different working conditions. For example, the gears commonly used in transmissions on highways are often direct gears or overdrive gears, while the gears commonly used in transmissions in mining areas are It is in the low gear area, and the slope is very large, while the port tractor usually has a large load and the slope is small. Therefore, in order to improve the reliability of the vehicle and collect a large amount of information on the working conditions and vehicle use information, the design and production of the vehicle can be improved, and the reliability of each assembly of the vehicle can be effectively improved. However, the existing vehicle working conditi...
