Title:
SLOPE ESTIMATION SYSTEM AND METHOD FOR ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/092604
Kind Code:
A1
Abstract:
Provided are a slope estimation system and method for an electric vehicle. The method comprises: using a pedal position sensing component (2) to measure a position variation of an accelerator pedal (M1) of an electric vehicle (M), and configuring a vehicle speed sensing component (3) to measure the vehicle speed of the electric vehicle (M); when the change amplitude of the position variation of the accelerator pedal (M1) from an nth second to an (n+k)th second is less than 10% of the position variation thereof at the nth second, and when the change amplitude of the vehicle speed of the electric vehicle (M) from the nth second to the (n+k)th second is less than 10% of the vehicle speed at the nth second, a control component (4) performing a weight estimation program, so as to obtain the vehicle speed of the electric vehicle (M) at the (n+k)th second and the weight of the electric vehicle (M); using a torsiometer (1) to measure the torsion of a motor of the electric vehicle (M); and on the basis of the vehicle speed of the electric vehicle (M) at the (n+k)th second, the torsion and the estimated weight of the electric vehicle (M), the control component (4) further estimating a slope value of the position where the electric vehicle (M) is located. Therefore, the effect of improving the accuracy of estimating the slope of an electric vehicle is achieved.
