Description
Technical Field
The present invention relates to the field of mechanical transmissions, such as gear shifters, in particular to the field of automatic control of mechanical transmissions, such as automatic gear shifters, and more particularly to a shift control assembly.
Background
Shifters are a common component in automotive transmissions. In recent years, automatic gear shifters have become increasingly widely used in various types of automobiles of different brands and different models.
Generally, an automatic shift control device in the prior art includes two parts, a shifter and an Actuator Controller (ACM).
The gear selector can be mounted on the surface of the center console of the automobile as an appearance control part, and the actuating mechanism controller is mounted inside the center console of the automobile as a black box part with invisible appearance.
The two parts, the gear shifter and the actuator control, generally require separate power supply means, data processing means and communication means, respectively, i.e. at least two such power supply means, data processing means and communication means, respectively, which makes the overall cost of the gear shifting mechanism high.
In addition, due to the diversification of the models of automobiles, the gear shifter needs to be developed in various models according to the different models of automobiles, and the actuator controller also needs to be adaptive in structure and circuit design according to the different mechanical appearances of the gear shifter, so that the overall design cost is high.
For example, in the case of a bus communication system such as a CAN bus, a Microcontroller (MCU) in the shift-by-wire control unit (SBW) collects and processes sensor signals that reflect the position of the shift unit and converts them into data messages containing shift position information, which are sent to the bus. And a microcontroller in the actuating mechanism controller receives the data message through a bus to obtain gear shifting position information, and sends a gear shifting actuating signal to the gear shifting actuating device to control the gear shifting actuating device after calculating the gear shifting position. In this solution, the shift-by-wire controller and the actuator controller need to be provided with their own respective microcontrollers, which is costly. And the meanings of data messages sent by microcontrollers of different models of drive-by-wire shifters and the expressions of the positions of the shifters in the messages can be different, so that the technical scheme needs to carry out new software and hardware design on the circuit control of the microcontroller in the actuating mechanism controller aiming at different drive-by-wire shifters.
For another example, in another prior art solution, the common bus communication method is dispensed with for the shifting operation, and the functions of the shift-by-wire controller and the actuator controller are integrated by software and hardware design. The solution comprises only one microcontroller. The microcontroller collects and processes sensor signals reflecting the position of the gear shifter, and the sensor signals are converted into gear shifting actuating signals through hardware circuit signal collection and software control logic to be sent to the gear shifting actuating device. This solution reduces the cost with respect to the previous solution, but further enhances the relevance of the shift-by-wire and actuator controls in terms of mechanical and electrical coupling, often requiring redesign of the mechanical structure of the whole system and the software and hardware of the circuit control for different shift-by-wire. And the larger occupied space of the integrated module greatly weakens the flexibility of the technical scheme, and the design and adjustment of the installation space of the integrated module on different control consoles are always required to be considered.
The above-mentioned technical solutions in the prior art do not solve the need for quickly and inexpensively selecting corresponding actuator controls for different types of gear shifters, either the hardware quantity is large and the cost is increased, or the design of the original actuator controls needs to be substantially modified to match the corresponding gear shifters.
