Abstract

The invention belongs to the technical field of automation, and provides a control method and device for an electric vehicle throttle as well as a terminal device. The method comprises the following steps: acquiring a first voltage input by the electric vehicle throttle; performing linear normalization calculation on the first voltage to obtain a first aperture; finding a range of an interval in which the first aperture is located in a preset correction chart according to the size of the first aperture; obtaining an endpoint value of the range of the interval in which the first aperture is located and a growth factor corresponding to the endpoint value; calculating a growth factor of the first aperture according to the endpoint value of the range of the interval in which the first apertureis located and the growth factor corresponding to the endpoint value; correcting the first aperture according to the growth factor of the first aperture to obtain a second aperture; controlling output torque of an electric vehicle according to the second aperture, and controlling a speed of the electric vehicle according to the output torque. An embodiment of the invention make a driver feel thatthe control is easy, thereby improving driving experience and safety.

Description

technical field [0001] The invention belongs to the technical field of automation, and in particular relates to a control method, device and terminal equipment for an electric vehicle throttle. Background technique [0002] The accelerator opening of the electric vehicle corresponds to different voltage signals, and according to the voltage signal, the corresponding torque (voltage, current) output by the motor is controlled to control the speed of the electric vehicle. [0003] At present, when the driver needs to accelerate through the accelerator opening, he directly increases the accelerator opening, and controls the motor to transmit the corresponding torque according to the voltage signal corresponding to the increased accelerator opening to control the acceleration of the electric vehicle. However, the relationship between the existing accelerator opening and the corresponding voltage signal to control the corresponding torque transmitted by the motor is a linear rela...
