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, requesting a shift.
- It then checks if the position value of the brake pedal, 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, while performing the requested shift, 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 requested shift.
Potential applications of this technology:
- This method can be applied in vehicles with automatic transmissions to improve the shifting experience and optimize gear changes.
- 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 unwanted gear shifts when the driver lifts their foot off the acceleration pedal, ensuring smoother transitions.
- It prevents unnecessary gear changes when the brake pedal is not pressed firmly enough, avoiding abrupt shifts.
Benefits of this technology:
- By controlling the transmission based on the conditions described, the method enhances the overall driving experience by providing smoother gear shifts.
- It helps to optimize the performance and efficiency of the vehicle by ensuring appropriate gear changes based on the driver's actions.
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.
