METHOD AND DEVICE FOR CONTROLLING A TRANSMISSION OF A VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17951901 titled 'METHOD AND DEVICE FOR CONTROLLING A TRANSMISSION OF A VEHICLE
Simplified Explanation
The patent application describes a method for controlling the transmission of a vehicle based on certain conditions. Here is a simplified explanation of the abstract:
- The method starts by determining if the controller receives a signal indicating that the driver has lifted their foot off the acceleration pedal, which indicates a shift request.
- It then checks if the position value of the brake pedal, as detected by a sensor, is below a certain reference value when the acceleration pedal off signal is received.
- If the brake pedal position value is equal to or greater than the reference value, it further checks if the gear shifting progressing rate of the transmission is below a certain reference value.
- If the gear shifting progressing rate is below the reference value, the method controls the transmission to hold the lift foot up (LFU) shift.
Potential applications of this technology:
- This method can be applied in vehicles with automatic transmissions to improve the shifting process based on the driver's actions.
- It can be used in various types of vehicles, including cars, trucks, and motorcycles.
Problems solved by this technology:
- The method addresses the issue of improper gear shifting when the driver requests a lift foot up (LFU) shift.
- It ensures that the transmission holds the LFU shift only when specific conditions are met, preventing any potential safety or performance issues.
Benefits of this technology:
- By controlling the transmission based on the driver's actions and specific conditions, the method enhances the overall driving experience.
- It improves the accuracy and efficiency of gear shifting, leading to smoother and more responsive vehicle performance.
- The method helps prevent any unintended gear shifts and ensures the transmission operates within safe and optimal parameters.
Original Abstract Submitted
A method for controlling a transmission of a vehicle includes: determining whether a controller receives an acceleration pedal off signal corresponding to a lift foot up (LFU) shift request signal from an acceleration pedal sensor; determining whether an output signal value of a brake pedal sensor detecting a position value of a brake pedal is less than a brake reference value when the acceleration pedal off signal is received; determining whether a gear shifting progressing rate of the transmission performing a LFU shift in response to the LFU shift request signal is less than a progressing rate reference value when an output signal value of the brake pedal sensor is equal to or greater than the brake reference value; and controlling the transmission to hold the LFU shift when the gear shifting progressing rate of the transmission is less than the progressing rate reference value.
