Embodiment Construction

[0044]The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0045] The inventor found in the process of realizing the invention that: in the prior art, since the contour map of the accelerator pedal configured in the ECU of the vehicle is fixed, in order to make the accelerator opening expected by the driver and the actual accelerator pedal The opening degree is the same or close, so that the driver's expected vehicle output performance is consistent or similar to the actual vehicle output performance. The driver needs to adjust his pedaling h...

Abstract

The invention provides a throttle opening adjusting method and device. The throttle opening adjusting method is applied to an ECU in a vehicle; and the ECU has a self-learning mode; in the self-learning mode, the vehicle is in a static state. The throttle opening adjusting method comprises the steps of obtaining an actual throttle opening when a driver performs at least one stepping action on an accelerator pedal on the basis of at least one expected throttle opening when entering the self-learning mode, wherein the expected throttle opening is a throttle opening in an accelerator pedal contour map; and on the basis of the actual throttle opening and the expected throttle opening, updating a throttle opening in the accelerator pedal contour map so that the updated accelerator pedal contourmap is adaptive to a driving behavior of the driver. According to the throttle opening adjusting method, the accelerator pedal can automatically adapt to the driver without the driver to passively adapt to the accelerator pedal; and therefore, the user experience is better.

Description

technical field [0001] The present application relates to the technical field of driving, and more specifically, relates to a method and a device for adjusting an accelerator opening. Background technique [0002] Electronic Control Unit (Electronic Control Unit, ECU) is a microcomputer controller dedicated to vehicles, also known as "driving computer". The ECU is equipped with a contour map of the accelerator pedal. The contour map of the accelerator pedal shows the engine speed, wheel The relationship diagram between torque and accelerator opening. When the vehicle is running, the ECU obtains the accelerator opening in real time, and determines the wheel torque at the current engine speed according to the contour map of the accelerator pedal, and further determines the current output performance of the vehicle. [0003] However, in the actual driving process, the expected accelerator opening when the driver steps on the accelerator pedal often has a large deviation from th...
