Embodiment

[0035] Such as figure 1 As shown, input the analog signal of the throttle opening and the gear position signal into the single chip microcomputer MC9S12G128. The single chip microcomputer has an AD conversion function, and the AD conversion can be realized after the system configuration; the braking signal is a switch signal, through the photoelectric coupling Filter out interference; the engine speed signal is shaped into a square wave signal by pulse signal through a voltage comparator. Since there is a certain functional relationship between the input variable value and the target speed ratio, the target speed ratio is obtained according to the input value of each sensor, and then the duty cycle of the output PWM signal value of the two PWM ports of the microcontroller is changed according to the target speed ratio value. Realize speed adjustment. During the adjustment process of the speed ratio motors, the two speed ratio motors work independently without interfering with...

Embodiment 2

[0044] The electronic control system includes a control circuit, a double-motor double-locking device, a power module, two speed-ratio execution modules, two speed-ratio motors, CAN network communication, an LED display, and a buzzer. The electronic control system mainly consists of a circuit board, a casing and a connector. The throttle opening signal and gear position signal input from the outside are input to the analog quantity of the single-chip microcomputer. The single-chip microcomputer has an AD conversion module inside, which converts the value of the analog quantity into a digital quantity, and then performs AD software filtering to obtain an effective value. At the same time, the vehicle brake signal is input. This signal is a switch value. In order to prevent interference, it needs to be input into the microcontroller through the switch signal circuit; the engine speed signal is input as a pulse signal, which is converted by the pulse measurement circuit, and the s...

Abstract

The invention discloses a dual-motor regulated CVT electronic control system and method. The control system includes a single-chip microcomputer, and the throttle opening signal and gear position signal input from the outside are input to the analog quantity of the single-chip microcomputer, and the single-chip microcomputer has an AD conversion module inside; Input the vehicle braking signal to the single-chip microcomputer, this signal is a switch value; the engine speed signal is input as a pulse signal, which is converted by the pulse measurement circuit, and the speed is calculated by the period method and frequency method and input to the single-chip microcomputer; the single-chip microcomputer is based on the above input signal and target The functional relationship between the speed ratios, calculate the target speed ratio value, the target speed ratio value changes the PWM duty ratio value of the two motor executive modules, and continuously coordinates and controls the speed of the two speed ratio motors, so that the actual speed ratio value is constantly approaching the target speed. Ratio, and finally reach the target speed ratio; through the locking module to lock the motor when the two speed ratio motors are not working, to exert the best performance of the vehicle.

Description

technical field [0001] The invention relates to a CVT gearbox in an automobile, in particular to electronic control in a double-motor CVT gearbox. Background technique [0002] The automobile industry took the lead in developing in Europe and North America. After more than 100 years of development, the automobile industry has matured. However, with the rapid development of automobiles, people have higher and higher standards for automobiles, mainly reflected in comfort and safety. , driving performance and economy. Cars bring great convenience to society, but with the increasing number of cars, energy crisis and environmental pollution follow. [0003] Therefore, technology is still in constant innovation, and cars will develop in the direction of reducing energy consumption and reducing pollution emissions in the future. A continuously variable transmission (Continuously Available Transmission, CVT) is a transmission that can continuously change the speed ratio. The CVT h...
