Description

technical field [0001] The invention relates to a motor vehicle drive assembly, in particular to an adaptive transmission sensor drive assembly. Background technique [0002] In the prior art, electric vehicles, motorcycles, and electric bicycles basically directly control the current or the throttle to control the speed through the speed control handle or the accelerator pedal, or use the manual mechanical automatic transmission mechanism to realize the speed change. The operation of the handle or accelerator pedal depends entirely on the driver's operation, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the engine or motor, and stalling. [0003] Motor vehicles need to achieve intelligent control of current or throttle, and load or torque are important parameters. The measurement of this index generally uses a variety of sensors to obtain relevant parameters respectively, and then make judgments. For...

Problems solved by technology

However, this sensing device is structurally designed to be installed on the wheel hub. Small motorcycles or electric bicycles are light in weight. If they are installed at the center of the rear wheel, the center of gravity will be tilted backward, which will affect the safe driving performance, and structurally quite complicated

[0004] Other transmission sensing devices that are operated and controlled by the rider only based on experience without knowing the driving resistance inevitably have the following problems: 1. When starting, going uphill and with a large load, due to the increase in driving resistance, the electric vehicle Speaking of it, it will force the motor speed to drop to work in the low-efficiency area, causing the motor to stall, heat up, or even stop rotating when the battery increases the supply current.

2. Since there is no driving torque-driving resistance sensor, it lacks "road sense" and cannot reflect the driving torque of the motor, the mechanical efficiency loss and motion resistance of the transmission system, and the change in the transmission inertia of the wheels and the rotating parts of the transmission system, so it is difficult to realize the driving force and driving force. Resistance Torque Balance Control

Can not solve the electric vehicle motor torque-speed characteristics, very incompatible with the driving requirements of the vehicle, often contrary to it, and difficult to achieve scientific problems of precise control

3. The installation space at the driving wheel is small, and it is difficult to accommodate the automatic transmission and other new technologies after the motor is installed;
