Detection method for motor vehicle loads

Abstract

The invention discloses a detection method for motor vehicle loads and belongs to a load detection method of an electronic controller for performing automatic speed changing transformation on a manual speed changer. Mainly, an angle detection device for detecting different angles is arranged in a vehicle body, the angle detection device is triggered to be opened or closed through vehicle body angle changes of a motor vehicle in the driving process so that the load condition of the motor vehicle can be determined, the load condition of the motor vehicle is provided for the electronic controller of the motor vehicle, and the electronic controller issues a motor vehicle gear shifting command. The detection method has the advantages that the size of the loads can be judged by detecting the vehicle gesture of the motor vehicle, and gear shifting information can be accurately provided.

Description

Technical field [0001] The invention belongs to the technical field of motor lunch load detection, and in particular relates to a load detection method for an electronic controller configured with a manual transmission to implement automatic transmission modification. Background technique [0002] The implementation of automatic transmission transformation on a motor vehicle with a dynamic transmission involves two states of driving on a flat road and driving on a slope. Because the shift points are different in the two states, the load when the vehicle is driving on a slope To increase, it is necessary to delay upshifting and early downshifting to improve the climbing power of the maneuvering. The existing technical solution is to detect the engine speed and throttle opening, and the electronic controller judges the maneuvering by comparing these two parameters. Noon load is used to determine the timing of gear shifting, but this scheme often misconducts the sub-controller in pr...

[0002] The implementation of automatic transmission transformation on the motor vehicle with dynamic transmission involves two states of driving on flat road and driving on slope road, because the shift points of the motor vehicle are different in the two states, and the load of the motor vehicle when driving on the slope road is different. increase, the climbing power of the motor vehicle must be improved by delaying upshift and early downshift. The existing technical solution is to detect the engine speed and the opening of the throttle, and the electronic controller judges the motor speed by comparing these two parameters. However, this solution often misleads the electronic controller in practical applications, because the driver is forced by the road conditions and often loosens the gate when it should be enlarged, causing the electronic control The information obtained by the controller is inaccurate, and an inappropriate shift command is made, which makes the power of the motor vehicle to climb hills insufficient.
