Active control method of pedal effort for accelerator

摘要

An active control method of pedal effort for an accelerator comprises steps to actively vary pedal effort. When a vehicle having a controllable pedal effort accelerator pedal runs, the active control method can actively vary the accelerator pedal effort according to accelerator pedal manipulation habits of a driver, thereby improving the accelerator pedal manipulation efficiency of the driver.

1. An active control method of pedal effort for an accelerator, comprising:
a data storing step of storing Accelerator Position Sensor (APS) operation percentages information data at a predetermined time interval while a vehicle having a controllable pedal effort accelerator pedal is being driven; a manipulation habit change determination step of determining whether a present accelerator pedal manipulation habit of a driver when driving the vehicle has changed from a previous accelerator pedal manipulation habit of the driver when driving the vehicle previously by comparing the present accelerator pedal manipulation habit to the previous accelerator pedal manipulation habit based on the stored information data; and a pedal effort control step of determining a present accelerator pedal effort control value based on results of the manipulation habit change determination step, and controlling a present accelerator pedal effort of the vehicle being driven using the determined present accelerator pedal effort control value, wherein, at the manipulation habit change determination step, whether the accelerator pedal manipulation habit of the driver has changed or not is determined by calculating a gradient of a present APS operation percentage and a gradient of a previous APS operation percentage as a function of time and by comparing the gradients of the present and previous APS operation percentages to each other to determine a change in a gradient variation rate of the APS operation percentage by determining a variation in the gradient of the present APS operation percentage from the gradient of the previous APS operation percentage.
